The dense gunfire suddenly burst out, not very violently, just like many small drums beating together, forming a continuous clatter. Before the seven demons fell to the ground, they were attacked by dense barrage. Each bullet hit the demon, and the magic power attached to the bullet was strongly repelled, causing a violent burn. The burning demon armor became brittle and was obviously dented. The unprotected monster face and wings were directly exposed to the barrage, and were burned to melt.

The three big succubus rushed in front and were bombarded with the most intense bombardment. The armor collapsed in a thunderous skeleton. The flesh on the head and wings melted, leaving only the charred skeleton. They pounced on the ground on the spot, then burned from the inside out, and quickly withered and disappeared. The possessed demon roared back to the subspace, leaving three incomplete **. The other two big succubus were located in a relatively back position, but they also suffered heavy damage. They roared and retreated repeatedly, hiding behind the obstacles and did not dare to show their heads. Only the last two magical archers suffered very little attacks, calmly pulling out the magic bow and shooting two bright purple energy arrows.

"Kinetic energy barrier." Shuimu shouted immediately.

The mage team held the staff tightly at the same time and rushed hard. An instant translucent light blue energy barrier appeared in front of the door hole. It was very thin at first, but it was soon as thick as a wall. Two beams of demon energy arrows exploded violently, shaking the barriers fluctuated continuously, but failed to penetrate. The Siren's gunmen continued to fire, and the dense barrage passed through the energy barrier like a fog, and violently hit the magic magic archer. One magic magic archer died in the flames, and the other magic lapsed in panic after being seriously injured.

Gu Tie was very impressed. He admired the power of the enchanted bullets and the effect of the kinetic energy barrier. - According to prior knowledge, he already knew that this was a one-way energy protection, which could be shot from the inside to the outside, but could not be shot from the outside. Slow objects can penetrate the barrier, such as slow crawling turtles, but fast objects cannot. For example, rabbits. These siren wizards with melancholy have lost their natural blood magic power, but rely on their own efforts to practice to this level, which is indeed worthy of respect.

When the sirens saw the demons escape, they were so excited that they cheered and screamed. Shui Mo immediately frowned and shouted in a deep voice: "It's not time to celebrate yet. All soldiers change magazines. Reload bullets. The defenders lower the barrier level. The snipers search for the enemy." The gunmen immediately withdrew from the magazine in the air and loaded bullets hard. Now there are more bullets and fewer magazines. They can't shoot empty bullets, throwing the empty magazines aside. The mages also thinned the kinetic energy barrier, making the energy consumption less. The snipers also picked up the telescope to observe the distance. In a blink of an eye, the position returned to its previous rigorous state.

Gu Tie asked curiously: "Is this their first time participating in the war?"

"Simulation combat and exercises have been carried out many times, and the actual combat is indeed the first time," said Shui Mo.

Gu Tie nodded vigorously, knowing that Shuimai was definitely a general. He could actually lead the recruit Danzi to become a veteran. He was like patting Shuimai's butt and praised her loudly, but considering the danger of distracting her, he still didn't say anything nonsense and waited patiently for the next wave of attack. Not long after, the snipers shouted to call the police. Gu Tie quickly picked up the telescope to watch and found a dense range of demons. The leader was a demon-capturing, with dozens of big succubus behind, and there were many phantom demons and illusory demons.

"Sniper shoots freely." Shui Shuan shouted.

The snipers walked to the front row and set up sniper rifles to shoot in succession. Immediately, several big succubus were shot and bright firelights were lit on their bodies. But the other demons quickly formed into dense formations. The big succubus holding the shield rushed to the front, and the demons in the back row shot out a large number of black fireballs. These balls dragged the long tail of smoke and drew conspicuous arcs in the air.

"This is the devil's smoke bomb, they have to charge for forcibly." Xingcai Shi reminded him with the voice of the soul, not only to Gu Tie, but also to inform Ink. Because Ink has been in Xingcai Shi's body, it has established a certain relationship with Xingcai Shi and can accept the telepathy of Xingcai Shi. Ink hurriedly shouted: "Stay, this is the smoke bomb, the devil wants to use the smoke bomb to hinder our vision, and all retreat to establish a deep defense line. The defenders fixed the kinetic energy barrier and retreated, arranged a slowdown trap, and took their place, prepare..."

The black fireball fell outside the kinetic energy barrier and the rumbling explosion immediately spread violently, causing the visibility of the smoke outside the door to zero. "Retreat." Shuimu finally gave the order, and the Siren warriors packed their things in an orderly manner to retreat, establishing a new position more than fifty meters away. The defenders left the kinetic energy barrier, arranged a flat lunch box device along the way, and then established a new kinetic energy barrier in front of the new position. Next, the door opening was extremely quiet, so quiet that the air solidified.

Suddenly, several purple fire giant swords slashed the kinetic energy barrier at the hole, and then several big succubus rushed into the door hole and ran screaming with shields. But their shields were not big enough, they just covered their upper body and their lower body was exposed. "Fire, shoot your legs." Shui Mo called out loudly, lifted the gun and fired at the big succubus' knees. The dense gunshot burst out in the door hole, and the dense barrage bombarded the demon violently, and the arrogant demon forced the barrage. The legs of the demons in front fell down, and more demons rushed into the door hole, stepped on the demons in front and rushed forward, and some were also lifted up to make the second shield.

After a while, the demons rushed to the front of the position, less than ten steps apart. Shuimu shouted: "Start the trap."

The buried devices immediately erupted a thick yellow mist, filling the entire door hole. The demons seemed to be trapped in the mud, and each step was very difficult, and the running slowed down. But the Siren warriors' guns became more rapid, and the dense barrage never stopped. The demons burned one row after another, leaving behind broken and withered **.

In the end, four or five big succubus rushed to the front of the position, but were blocked by the kinetic energy barrier. They waved the purple fire giant sword and slashed in vain for a few strokes, and were beaten to the fire of both legs, kneeling in front of the kinetic energy barrier, and then shot to the fire of the whole body. Gu Tie watched the big succubus withered and degenerated, thinking that the attack had blocked again, so he gave Shuimu a thumbs up: "Good job."

Shuimu frowned and was silent for a while before saying, "The devil's methods should not be that simple."

"Indeed, the scream of the demon is very powerful, and it can shake the roof to the sky." Gu Tie recalled the battle between the demon and the evil spirit guards, and remembered the terrifying scream of the demon. At this moment, an extremely harsh roar broke out in the cave, as if a supersonic plane took off from the narrow cave, and the roar of the turbine engine continued to echo and superimpose.

"Fuck me, I'll do whatever I say. I'm such a crow's mouth." Gu Tie gritted his teeth and cursed.

"Strengthen the kinetic energy barrier." Shuimo shouted quickly.

Xingcai Shi said coldly: "This is a howling sound wave cannon. The kinetic energy barrier is useless. Build a sound silence barrier quickly."

"Silence barrier?" Shui Mo was stunned. Suddenly, he became a little desperate because the defenders did not have this ability.

"Then cover your ears and lower your head, and pray to the God you worship."

This time, Xingcai Shi used telepathy to send the sound to everyone present. The ink and the sirens covered their ears and lowered their heads. The harsh roar suddenly intensified. A purple light ball similar to a comet dragged a thick and long tail through the yellow haze and passed over Gu Tie's head. In this moment, Gu Tie felt that he was being run over his head by a roller, and his headache was almost exploded. The ears that had been buzzing suddenly felt a stinging pain, and then they were completely silent, and no sound was gone.

The ball of light flew past the position and landed on the ground and exploded in the rear, causing a devastating shock wave and scream. Several soldiers in the back row immediately rolled up and flew up, and blood kept flowing out of their eyes, ears and noses. Gu Tie endured the headache and cheered up, released his psychic hand to catch the wounded, and then called on the ink around him. Ink seemed to be unconscious, and he could not hear his voice.

Xingcai Shi said coldly: "Your ears are broken. They are all unconscious and take them away immediately."

There were fifty tall and fully armed women here, each of which was not small. Gu Tie had never caught so many people, and the total weight would probably exceed the limit. The situation is urgent now, and he didn't think about whether he could do it. He released a large number of psychic hands to grab each Siren warrior and every piece of equipment. Then he turned around and ran wildly. The position at the door was just the first line of defense, with only fifty people defending, and the second line of defense was in the hall at the end of the door, which was also a real position, gathering two hundred warriors and three hundred mages. When they saw Gu Tie coming back with Shuimu and his sisters, they all screamed and stood up.

"The devil will attack soon, all stay at their posts, and the medical soldiers come."

Gu Tie yelled loudly, but he couldn't hear his voice anyway, so his voice was too loud. The panicked Siren warriors finally calmed down, and medical soldiers appeared one after another. Gu Tie sent Shuimu and others to the back of the defense line, leaving the minor wounded to the medical soldiers, and brought several seriously injured people to the rear. These female Siren were blown away by sound wave cannons at close range, no longer breathing or heartbeat, and strictly speaking, they were dead. After checking, he gritted his teeth and said, "Is it too late?"

"The soul has not left **, and it can be used as a sacrifice in theory. Also, your voice is a little smaller, and you really think that the fool is the smartest, and the deaf has the biggest voice." Xingcai Stone turned into a human form in the light shining light, poking two index fingers into Gu Tie's ear holes, and quickly lowered the spell. Gu Tie's shocked ears quickly rebuilt and quickly restored his hearing. The newly restored hearing is more sharp than before, and many noisy sounds pour in like a tide. His own plop heartbeat, the soldiers' nervous gasps, the wounded moans of pain, the medical nurses' running, and the demon howling from the door hole, all kinds of sounds are clear and chaotic.

Gu Tie was silent for a while and suddenly said, "My head hurts. Can you make me smarter after you repair it for me?"

Xingcai Shi tightened her beautiful brow and patted Gu Tie's shoulder: "Stop talking, sacrifice immediately."

Gu Tie rubbed the painful temples, quickly stripped off the equipment and clothes of the wounded, and stripped them into a barely-smoked Aries and offered sacrifices to Xingcai Shi. After Xingcai Shi accepted these sirens, he released several new sirens. These substitutes were mentally prepared, but after they came out, they didn't say anything nonsense, quickly put on armor stained with their companions' blood, and picked up their companions' weapons.

After the Star Color Stone released a new Siren, it flew quickly between the positions and quickly arranged layers of sound silence barriers. Gu Tie injected a quick healing medicine for a while before coming to Shuimu. Shuimu had woken up, but her face looked very ugly. She was originally very pale, but now she was almost transparent, and there was another dark circle around her eyes, which looked very much like smoky makeup.

When she saw Gu Tie, she took the initiative to ask: "How are they?"

"I'm going back to rest, where are you?" Gu Tie asked.

"The head buzzed and the ears buzzed too. Thanks to the master, otherwise it would be over." Shui Mo said.

"This is what it should be. Xingcai Stone is building a sound-silence barrier that can resist the howling sound-wave cannon, but I hope you have radio." Gu Tie noticed that the noisy battlefield was unknowingly quiet. Three or four meters apart, there were obviously several soldiers talking, but he couldn't hear anything. The sound-silence barrier separated the entire battlefield layer by layer, and divided the positions into "small compartments". The soldiers in the compartments could talk to each other. However, there was no communication between the compartments.

Shuimu shook her head and said, "Psychics usually do not use radios. The army with a large number of mages will not be equipped with radios. The mage's psychic energy will hinder the radio, and there are various precision electronic devices. But this is not a big problem. I will use sign language instead." She patted a soldier beside her and gestured with her hands a few times. The soldier nodded, patted the shoulders of his companions around him, and quickly gestured to tell Shuimu's command. Next, the soldiers quickly passed the sign language, and soon it spread throughout the entire position. Shuimu explained, "I told them to communicate with sign language next, and everyone should pay attention to the commander's gestures."

"Well, they are all well-trained." Gu Tie exclaimed.

Suddenly, a purple light ball shot out from the door hole. Because of the sound insulation barrier, Gu Tie didn't hear any sound in advance, and was shocked. The same was true for ink, so he widened his eyes and tightened his fists. His teeth were tightly biting his black lower lip. Under the gaze of everyone, the light ball easily penetrated the kinetic energy barrier without weakening at all, but then it continued to weaken. At first it was as big as a basketball, but after a small circle it turned into a football. Then a small circle it turned into a solid ball, then a tennis ball, and then a table tennis ball, and finally completely disappeared. The sound insulation barrier took effect, with a very significant effect, completely absorbing the power of the sound wave cannon.

Gu Tie breathed a sigh of relief and looked at Xingcaishi on the other side of the position and praised: "Dear, you are my angel, come, kiss me." He gave a blowing kiss. Xingcaishi turned his back to Gu Tie, but seemed to know what Gu Tie was doing. She picked up a lid of an ammunition box and waved it back, as if saying: "Catch it back and take back this disgusting thing."

Gu Tie couldn't help laughing. When Shuimi saw it, he suddenly felt that these two were not like warlocks and demons, but more like couples.

A series of energy arrows were shot out densely from the door opening, bombarding the kinetic energy barrier triggered a violent explosion. The sound was isolated from the sound, but the vibration of the ground could be clearly felt. Shuimiao stood up and gestured hard, allowing the defenders to strengthen the kinetic energy barrier and allow the gunmen to continue firing. The machine gunners who were facing the door opening immediately opened fire with all their might, pouring out a barrage of no less.

The door hole was filled with dust caused by explosions. Siren warriors could not see the demons, and the demons could not see the Siren warriors. They fired violently through the door holes. The metal barrage and energy barrage intertwined each other, causing a violent explosion. From time to time, there was a sonic cannon that penetrated the kinetic energy barrier, which scared Gu Tie in cold sweat. However, the sound silence barrier was very effective. The sonic cannon always weakened quickly and disappeared in an instant. Occasionally, the sonic cannon did not completely disappear, nor did it hurt anyone.

Gu Tie looked at it for a while and couldn't help asking in his heart: "Why can sound wave can penetrate the kinetic energy barrier?"

When Xing Caishi heard his voice, he also answered telepathically: "Have you returned your knowledge of high school physics to the teacher?"

"Yes, my dear, do you want to discriminate against illiteracy?" Gu Tie asked shamelessly.

Xingcai Shi was silent for a while before answering: "The kinetic energy barrier only takes effect on kinetic energy. The so-called 'kinetic energy' is the energy of the movement of objects. The warheads flying at high speed have kinetic energy, and the energy arrows flying at high speed also have kinetic energy. Although the energy arrows do not rely on kinetic energy to kill the enemy, they rely on kinetic energy to hit the enemy. There are two conditions for the kinetic energy barrier to take effect. The first is the direction and the second is the size. Only from the outside to the inside and the size exceeds a certain degree of kinetic energy can the resistance of the kinetic energy barrier be stimulated. The killing principle of the sonic cannon is strong sound waves, and the energy attribute is fluctuating energy, which is different from the so-called 'kinetic energy', just like the difference between water waves and water flow."

Gu Tie thought hard for a while before smiling and said, "I understand halfway, my physics knowledge still retains my junior high school level."

Xingcai Shi was silent for a while, and suddenly gritted his teeth and said, "I swear, I will give you tutoring your homework."

After a while, the demon energy arrow stopped shooting, and Shuimu raised his hand to signal the ceasefire, staring at the door opening without blinking. The door opening was filled with explosion dust, which was difficult for the naked eye to see clearly. After a while, the dust gradually dissipated, revealing the doorway that was riddled with holes by the barrage. There was no demon outside the door opening. A huge giant bulldozer that was almost filled with the entire door opening was slowly driving into the doorway. It was not fast, but very stable. After the heavy bucket as thick as a city wall, countless mutants were following.

Gu Tie was stunned and asked in amazement: "Can the kinetic energy barrier resist this thing?"

"It's ok, but... its thrust is too strong, and the defenders will be exhausted." Shuimu gritted his teeth and gestured continuously. The soldiers replaced the bazooka and shot at the bulldozer. Explosions occurred again and again on the bulldozer, but the bulldozer was still advancing steadily. This cannot be blamed for the weak power of the bazooka. It is okay to use the bazooka to attack helicopters and armored vehicles, but it is already difficult to fight tanks. This bulldozer is too big, bigger than any tank, so of course the bazooka cannot be driven.

Under the noses of Gutie and the Six Hundred Siren Warriors, the bulldozer slowly drove into the hall and easily crushed the kinetic energy barrier. It was not until this time that the Siren Warriors found an opportunity to destroy the bulldozer from the side with a rocket launcher. However, this was useless. A large group of mutants following behind the bulldozer roared into the hall, followed by the Great Successor wielding the Purple Fire Sword.

Shuimu jumped up with a gun, gestured and shouted: "Standing your position."

……………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………

The mutants screamed and rushed to the position, and were torn to pieces by gunfires in a blink of an eye, but before they died, they had attracted enough fire. The great succubus rushed into the position of the sirens warriors, wielded their giant swords and rushed forward. In the blink of an eye, the fire was blown by the machine guns. But before they died, the purple fire-burning sword blade was stained with black blood. The illusion demon fired energy arrows in the air, triggering explosions one after another, and were shot down by the snipers in a short while, but before they landed, the explosion energy arrows had blown away many soldiers... This is a microcosm of the battle, the two sides were constantly exchanging lives, and the soldiers were just a string of numbers that were constantly consumed.

Another energy arrow fell not far ahead of Gutie, and the two soldiers were blown up and rolled up. Gutie saw a splatter of black, not knowing whether it was soil or their blood. He hurried over and found that the armor on their backs had been exploded, and black blood kept flowing out of the cracks. This was not the first time he had seen this situation, so he knew what to do - quickly peel off their equipment with his psychic hand and then sacrificed it quickly. After a while, the two wounded disappeared, but there were two explosions ahead and on the left. He had no time to pack up the equipment on the ground, and he should hurry to look for the seriously injured in these two places.

Suddenly, a big succubus landed in front of him and waved his giant sword to slash. Gu Tie opened his eyes wide and stared at the giant sword that was getting closer and closer. When he was about to be hit, he turned around to dodge. The blade flew over his head, and a few purple fires splashed on his face, leaving a uncomfortable burning pain. He gritted his teeth and snorted coldly, turned around and pulled out the energy-gathering sword, and inspired the sword blade to penetrate the ribs of the succubus. The black sword blades all penetrated into the gap of the armor of the succubus. He shook the blade left and right a few times before pulling it out. The burning blood spurted out from the wound. The great succubus knelt on the ground in pain. He raised the energy-gathering sword again and cut off the great succubus' neck with one sword.

"When I was a soft nurse, I dared to come to me."

Gu Tie cursed and kicked the big succubus away, and continued to recover the wounded. Four more wounded men were taken back, and then there were three, five, four.... There were fewer and fewer Siren warriors left on the battlefield, and the ground was covered with black blood, like oil sprinkled all over the ground. But there were also many mutant corpses, densely packed on the ground, like a carpet of human flesh. The demons would definitely not be able to continue to sacrifice like this. The more troops they consumed in this battlefield, the more difficult it would be to another battlefield.

The question is whether the Siren warriors can hold on until the demons can't hold on.
