"No, no———"

A shrill scream came from the rooftop not far away, so harsh and painful that it penetrated the air barrier and directly passed into the ears of many fugitives who were robbing the road. When they turned and watched in the direction of the source of the sound, they found that it was a man who was chased by a mutant creature to the rooftop and had no way to escape. With the determination to die, he jumped down from the top of the sixteenth floor, but the frog-shaped human being chasing behind him suddenly popped out his tongue, like a frog dealing with flying insects, dragging the prey back from the air with its soft and sticky long tongue, and slowly savoring this rare delicacy.

Every warning tower was shooting wildly, with dense rain of bullets and whistling rockets constantly drilling into the mutant organisms and exploded, which also attracted the attention of these monsters and became new targets of attack.

A ferocious spider-like man climbed up to the top of the tower from the side, threw the bullet supply man out of the tower with his slender legs, and then sprayed out a spider silk with a strong corrosive effect, wrapping the unexpected machine gunner tightly. When the spider-like man pierced the soldier with a needle-like mouthpiece and injected the venom, the soldier tied up by the spider-wire only felt the blood in his body flowing faster and the blood was completely boiling. This pain was simply unbearable. The soldier's eyes turned pale and struggled desperately, but could not break free from the shackles. He could only expand his lips to the limit and let out a fearful howl.

Shouting and struggling have no effect on survival awareness. The toxins released by spiders spread rapidly in the soldiers' bodies along the blood vessels, destroying the platelet structure and tight cellular tissues, causing them to dissolve in a short period of time. The skin, muscles, bones... are not missing at all, and they are all converted into gravy that spiders can absorb with tubular mouthparts.

Dozens of armed helicopters hovered in the air, constantly projecting firepower towards areas with dense mutant creatures. With the lessons of the Hefei Battle, the helicopters maintained a hovering height that could not be attacked by mutant creatures. In addition to counterattacking with machine guns and rockets, there were also airborne cameras to capture this series of tragic scenes, which were quickly transmitted in the form of radio waves.

Yuan Zhicheng sat in the office on the 20th floor of the underground of New Lanzhou Base City, with a pale face and staring at the screen in front of him with his red eyes.

He saw the scene of the soldier being sucked by spiders on the alert tower. Although the picture passed back was not dubbed, Yuan Zhicheng could imagine what a terrible pain it was. The soldier opened his mouth until his death. Although yellow pus seeped out from his cheeks, fear and despair still solidified on his face and could never fade.

All these changes began last night.

The straight line distance between the New Lanzhou base city and the abandoned city Lanzhou is about 20 kilometers. Except for the New Guiyang under construction, New Lanzhou is the closest to the abandoned city among all base cities.

The proximity means danger and also means rich returns. From commonly used materials to essential weapons and ammunition, New Lanzhou maintains a smooth supply between the abandoned cities, and it is also convenient to transport troops entering the city to hunt mutant creatures. Therefore, the speed of obtaining silver bones and crystals from the New Lanzhou base city is very fast and the number is also large.

Living to Yuan Zhicheng's age, being cautious and careful has become an instinct. In addition to normal sentry patrols and electronic monitoring, he also ordered that all abandoned cities in his jurisdiction must be kept on airship alert for 24 hours. This practice is of course based on the strong supply of materials in the northern theater. It is precisely because of this that when the mutated creatures in the abandoned cities have abnormalities, the defenders of the New Lanzhou Base City were able to respond fifteen minutes in advance.

Without any warning, the damn monsters rushed out of the abandoned city and rushed towards the New Lanzhou base. Their goals were so clear that they were even more accurate than the guidance direction drawn by the computer. The twenty-two large and large strongholds and checkpoints set up along the way were swallowed up by the creatures. The surveillance post closest to the abandoned city just released a distress signal, and completely cut off contact.

Fortunately, the airship has been responsible for monitoring over the abandoned city. It records the entire process of this emergency. The mutated creatures inside the abandoned city are not specifically targeting the New Lanzhou base, but are fleeing on a large scale. Just like a red wolf appeared in the camel group living on the Pampas grassland, causing these monsters to flee in all directions. They are aimless and flee from the abandoned city as fast as possible. Among them, the number of this stock that pounced on the New Lanzhou base is about 300,000. With the subsequent and surrounding parts that are attracted, it is roughly estimated that it is about 550,000.

They had no idea what death was, and they were not even afraid of death. The vanguard of the biological frenzy rushed directly into the minefield outside the base city, causing a series of explosions. More monsters who were fearlessly dying stepped on the bodies and flesh of their companions, rushing against the city walls like crazy. The scene was extremely spectacular, as if fireworks were blooming everywhere during the Chinese New Year. The only difference was that in addition to gunpowder smoke, there was also extremely strong blood in the air.

The refugees gathered outside the city were first slaughtered.

There are about 500,000 civilians outside the city of New Lanzhou, which is densely populated in many bases and cities. Yuan Zhicheng never asked about the issue of people gathering, but just regarded them as a source of recruits. When needed, he sent people out of the city to choose, and usually let them develop. He never expected that hundreds of thousands of civilians would be flooded by the biological craze under his nose. Except for some strong people who escaped by chance, the remaining old and weak were killed.

Now, corpses are everywhere outside the city. The refugee areas and minefields that were originally separated are no longer boundary. There are traces of explosions everywhere, and corpses are chewed everywhere. The dense mutant creatures are strolling in the tents and garbage. They hold human heads in their mouths, claws hold their thighs and arms. The huge number of refugees provides sufficient food for the mutant creatures. The hungry monsters are full in just one night. In the scene taken by the air force, some mutant creatures with special appearance are eating while excreting. There are also some guys with special tastes who have become very picky, specializing in cutting human corpses with their claws, eating only the heart and liver, and throwing away other parts of the body as garbage.

Yuan Zhicheng did not have the rich experience of Su Hao from the future world, so he naturally would not understand that this chaos that occurred during the full moon period was called "Moon Tide".

Although the biological frenzy that occurred in New Lanzhou was not as huge as the Battle of Hefei, the power and evolutionary state of mutated creatures had exceeded that of that time.

As the core city of the northern war zone, New Lanzhou is far from comparable to New Nanyang in terms of construction scale and defense capabilities. Taking the data comprehensive assessment by the military as an example, New Lanzhou's various defense infrastructures exceed eleven times more than New Nanyang, and its defense intensity exceeds about nine times.

In addition to the existing defense forces in the city, Yuan Zhicheng urgently dispatched fifteen divisions to siege New Lanzhou from all directions. Just last night, when the airship troops had just received a warning that the biological frenzy had not yet arrived in New Lanzhou, Yuan Zhicheng even felt that this was an opportunity to wipe out hundreds of thousands of mutated creatures in one fell swoop. If you have good luck, you might take the opportunity to recapture the abandoned city of Lanzhou.

The tragedy that happened outside the city, even a ruthless person like Yuan Zhicheng couldn't help but want to tremble.

The bodies of hundreds of thousands of dead refugees were piled up in mountains, and the degree of tragic and cruelty was even worse than that of the virus outbreak. What was even more terrifying was that the mutant creatures did not focus on the prey they had already killed, and they quickly set their sights on the base city.

Like New Nanyang, most of the defense forces in New Lanzhou are concentrated inside and at the top of the two outer walls. Although there are many warning towers in the city, most of them are concentrated in military-controlled areas and their locations are also scattered. Although the outer wall was designed with consideration of firepower concentration and personnel equipment, it was built to create a bastion that can be hit hard by multiple faces, neither the designer nor the builder expected that the evolution speed of the mutated creatures would be far beyond expectations.

Instead of spreading along the city wall as they imagined, they concentrated their efforts to break through the city gate in the south.

Yuan Zhicheng will never forget that scene until his death.

Thousands of pigs, cattles and horses, who were over four meters tall, rushed in front. They used their thick skin and thick bodies as shields to block the bullets shot from the city wall. The skin of these monsters was extremely thick, especially large pieces of connective tissue at the shoulders, knees, joints, etc.... The 7mm machine gun bullets can only cause limited damage to them. Even if they were hit by a 30mm machine cannon, they may not be fatal on the spot. They howled and rushed to the wall near the southern city gate, and hit hard with their bodies and fists. Although they could not shake the city wall, they gradually piled up at the foot of the city wall based on the corpse, forming deliberate "meat mountains".

The soldiers guarding the city soon discovered the problem. Just as they were busy mobilizing flamethrowers and calling for air support, trying to burn out the corpses of the giant mutant creatures piled up under the city wall and exploded, a second batch of attack waves followed.

It was a large number of dogs, cats, blood corpses, and agile mutant creatures with ferocious faces, flexible movements, strong jumping ability, and extremely fast running speeds. Ground obstacles have no effect on them at all, and the hit rate of dense strafing is also extremely low. These extremely flexible monsters climbed onto the dead pigs and cattle people and jumped up to the city walls in three or two. In order to solve these guys, the city guards had to split their manpower and specialize in hand-to-hand combat. Just when loopholes inevitably appeared on the weapon shooting surface, the most terrifying and deadly third wave of attacks began.

Tens of thousands of mosquito-shaped and fly-shaped humans appeared. Although they had wings, they could only glide at a low altitude within a limited distance and could not fly like real insects. Despite this, the gliding distance of tens of meters each time was enough for them to avoid bullets, calmly approached the thick city gate steel gate, and spewed out a bunch of concentrated liquid with a strong sour and rotten atmosphere.

The Black Era has entered its third year. The viruses in mutant organisms are undergoing new changes. Unlike the initial virus outbreak period, the parasitic effects aimed at infecting the human body, they have adapted to new hosts and have continued to evolve towards their own strengthening. The most eye-catching manifestations are the strengthening of the skin, bones, muscles, etc. of the mutant organisms, as well as the emergence of offensive weapons.

In addition to teeth and claws, the external structure of some insect-type human-like ejectables comes from acids and venoms in the body, and is also one of the weapons.

The three waves of attacks were connected in time, and the cooperation was perfect. The defenders who were busy dealing with the mutated creatures rushing up the city wall could not form a barrage with dense strafing. They could only watch the large ball of acid corrode the city gate steel gate and emit strong white steam. In the clear "hiss" sound, the thick and strong steel gate gradually became thinner, and small holes visible to the naked eye appeared... Although this process took nearly four hours, Yuan Zhicheng had enough time to draw troops from other areas for support.

But both himself and the officers' corps around him had forgotten one thing--the base city is not just composed of soldiers. Outside the military-controlled area, inside the first city wall, there were as many as hundreds of thousands of paid crystals and silver bones, and they believed that civilians could be obtained forever safe.

From the beginning of the biological siege to siege the base, the situation in the civilian areas in the city became chaotic.

According to the base city management regulations, civilians are strictly prohibited from approaching the city walls under any excuses. However, such requirements for safety and vigilance cannot stop civilians from contacting information outside the city. Especially when refugees outside the city were hit by the craze of mutant creatures and hundreds of thousands of people screamed in despair, almost every civilian in the city looked like a mortal face and was trembling unconsciously.

The experience of refugees outside the city may be the reality they are about to face. Although there are walls and tens of thousands of soldiers guarding the city, no one knows whether these seemingly impeccable defense facilities can really work?

The military will never disclose information to the public, but civilians have many ways to know what they want from various channels. They get bricks, stones, wood and other building materials and build a temporary lookout on the top floor of the building in the base city. In this way, their eyes were able to cross the city wall and see the terrible tragic situation of corpses everywhere outside the city.

"Why, why did this suddenly turn out like this?"

"Why did those man-eating monsters suddenly leave the city? What happened? Could this be another conspiracy that we don't know?"

"We...what should we do now?"

The civilian district in the base city suddenly became chaotic. All kinds of unfounded speculation and news were flying all over the sky. The civilians who were in horror were like ants blowing up their nests, looking for a way out. They began to snatch shops, break into strangers' rooms, and looted all the things worth taking. This chaos and turmoil are no different from when the virus broke out two years ago. The only difference is that the civilians are more sober and calm than at that time. They are very clear about what they need, and understand the difficulties and situations.

What exactly is what you need most in a desperate situation? The targets of robbery are mostly focused on food and weapons. Many people use existing materials to reinforce their doors and windows. Three or two of them are in a group and more than a dozen are in a group. They either attack the "A" area where the rich gather, or choose a spacious enough building in the "H" area to pile up all the robbed items, then seal the entrance with wooden boards and cement, hold various weapons, and become the contents of their own "cans" with fear.

The civilians are very clear about the difference between humans and monsters. Once they leave the base city, they will never be able to escape the hunting of mutated creatures in the wilderness. There is no place safer than in the city. As long as the scope of robbery and chaos does not affect the military-controlled areas, as long as the outer wall defense line can be maintained, they will always have a way out.

However, not everyone thinks so.

Some civilians felt that staying in the city with a siege of creatures was simply a death sentence. They wanted to leave this dead place. Through the observation of the rooftop observation deck, they found that most of the mutated creatures gathered at the city gate in the south. In the other three directions, especially in the north, there was almost no shadow of the mutated creatures. With their latest discoveries and the strong desire to survive, these civilians flocked to the North Gate Guard Area of ​​the base city, shouting, begging, and crying at the soldiers guarding the city gate... There was only one goal - let us go out and let us go now

Of course, this requirement will be rejected by the city guards. When a strong survival psychology collides with the cold reality, and hope suddenly becomes despair, people's thinking consciousness will soon be dominated by anger and rage.

"Why not let us leave?"

"Why should I close the city gate?"

"I'm going out and going out"

I don't know who opened the first mouth, and cursed fiercely at the soldiers guarding the northern city gate. Then, thousands of civilians participated in almost the same time and cursed. The shouting quickly turned into actual actions. People picked up stones and various debris and threw them hard at the city gate ward. However, the reply received was just a machine gun roar and a series of bullets shot at the crowd.

The fugitives dispersed. They did not reduce their deep hatred. Under the control of this painful, hatred and anger, civilians who were unable to meet began to deliberately disrupt the order in the city. They set up obstacles on the road in the base city; overthrow the military vehicles that were parked on the roadside and unattended; or Yu Qian smashed the military checkpoints and warning towers with homemade incendiary bombs...

In normal times, they wouldn't dare to do this at all.

Now, hundreds of thousands of mutated creatures are gathered outside the city. God knows whether this city can be defended? Those soldiers have no time to take care of themselves, so where can they still have the time to take care of us?

Why can only soldiers inject enhancement agents?

Why can only soldiers enjoy food rations?

Since I can't get anything, you won't let me go out, so just stay and die together
