The Frozen Fortress is located in the north and has a high altitude. Especially in severe wind and snow weather, the air pressure will become lower. When many people first come here, they will feel that every breath they take is robbing the blood of oxygen.

, the chest is depressed and I can’t breathe.

The howling wind raised the flying snow all over the sky, hitting the face as sharp as a knife. The night before dawn was so dark that even the torches lit with special fuel on the city wall could only illuminate a few meters around.

area, and further away, the light will blend into the endless night, and nothing can be seen in the darkness outside the city wall.

Just as the recruits and veterans were chatting, a sharp sound suddenly came from behind.

"Boom!" Some kind of luminous object rose from the military camp and rushed into the sky. When it reached the top, it suddenly burst out with strong light, illuminating the entire sky. It was as if another sun appeared in the night sky, making the entire frozen sky

The fortress area was as bright as day.

The veteran covered his eyes with his hands and looked at the luminous objects in the sky through his fingers. He couldn't help but feel a little confused.

What is this? I have never seen it before. It seems a bit like the roaring thunder used to convey military information, but it is a little different.

The Howling Sky Thunder will explode directly after it rushes into the sky. It basically only serves the purpose of transmitting signals once and for all. Now this thing falls at a very slow speed after it rises into the sky, as if it is suspended in the air, and it continues to emit strong light, which is extremely weird.

.

If this veteran is lucky enough to have come into contact with "outer space technology", he will know that this is a very common military item in modern warfare, flares.

"Hey" the recruit's voice suddenly sounded, with uncontrollable trembling, "What is that?"

The veteran looked back subconsciously. It was late at night, and it was originally impossible to observe the situation outside the city wall from the city wall. However, due to the flares, the area around the frozen fortress was as bright as day, and things that were originally shrouded in darkness were also exposed.

On the outside surface of the frozen fortress, the stretching flag spread to the end of the horizon. The ferocious saber-toothed tiger flag fluttered in the biting cold wind. Countless tribal warriors stood under the flag. Their eyes were as red as blood. The fervor was so frightening that it made people tremble.

His aura was leaking out without restraint, and his face was full of desire for killing.

"Enemy attack!" The veteran's mouth trembled and he muttered, and the cold sweat on his forehead turned into ice crystals in the cold wind and fell in thin puddles. He opened his eyes wide and roared with all his strength, "Enemy attack! Enemy attack!!!"

"Enemy attack! Attention all! Enemy attack!" The soldiers on the city wall also observed the heavily assembled tribal warriors. There were loud noises. Some of the ordering soldiers rushed to the military camp, some beat the war drums, and the roaring thunder roared again and again.

A wave was sent to the sky, awakening all the sleepers in the frozen fortress.

But what is puzzling is that the military manual is clear and the soldiers are very fast. To launch a surprise attack at night like this, it can be said that every second counts. If you attack a second earlier, you will shorten the reaction time of the city defense troops and catch them by surprise.

However, the tribal warriors gathered outside the city wall showed no reaction at this time. They just watched silently as the Frozen Fortress defenders issued orders to assemble without taking any action, as if waiting for something.

The soldiers on the city wall quickly entered a fighting state. The recruits were preparing to report the situation to the commander with the veterans. He glanced at the strangely silent tribal warriors from the pass and asked with great confusion: "What are these barbarians doing? Why?

at every turn?"

To be honest, the veteran had never seen such a situation, but these things were obviously not what he had to consider, so he said in a deep voice: "Don't worry about it, just do our job!"

The two left the city wall and passed the city gate bearing control room when the veteran suddenly stopped where he was.

The recruit quickly asked: "What's wrong?"

For the defense of any city, the city gate is the top priority. It is the passage connecting the inside and outside, and is the life of the defender.

If the city gate is secure, the enemy will have to spend a lot of money to fight on the wall and pay double casualties.

If the city gate falls, it will be nothing to the enemy, and no matter how tall the city wall is, it will be useless.

The veteran looked blankly at the closed city gate control room and muttered in a cold sweat: "What's going on? There should be elite guards here, why don't you see anyone?"

Only then did the recruits realize that the passage leading to the city gate control room was empty, and the guards did not know where they had gone.

The veteran swallowed hard and said in a deep voice: "Draw the knife."

The two men drew their sabers and cautiously walked towards the city gate control room.

The veteran touched the door handle, tested it gently, and found that the door was unlocked. He exchanged glances with the recruit, coordinated his breathing rhythm, opened the door suddenly, and rushed in.

The veteran found a figure in front of him, put a knife to the opponent's neck, and cursed: "Don't move! If you move, your head will fall to the ground!"

The veteran thought that a sabotage spy had infiltrated here, but when he saw the other person's face clearly, he was stunned: "Lord Ashuma?"

Asuma looked at the veteran with a smile on his face, pretending to be startled, and said with his heart covered: "Oh~ why are you holding a knife against me?"

Facing the superior affairs officer, the veteran quickly put away his knife. His mind was a little confused for a moment, and he stammered and asked: "My lord, are you here? Do you know that the barbarians are gathering troops?"

"Of course I know, otherwise what would I be doing here?" Asuma asked humorously and continued to do his own thing.

The veteran subconsciously focused his attention on Asuma's work at hand, and saw that he was holding some strange squares wrapped with red and blue thin lines, and was sticking them one by one on the bearings connecting the city gates.

The veteran asked blankly: "Sir, what are you doing?"

"As you can see." Asuma said as he placed the strange blocks, "I am planning to blow up this place."

"Blow it up?!" The veteran was shocked, "Why did you do that?!"

The smile on Asuma's face remained as usual, but there was a dangerous signal in his eyes: "What do you think?"

The blood suddenly drained from the veteran's face, and he yelled at the recruit: "This Fagao dog is a traitor, we must not let him destroy the city gate!"

"You know nothing about power." As soon as Asuma finished speaking, the originally thin and powerless affairs officer suddenly turned into a black shadow and rushed forward at a shocking speed.

Two waves of blood.

Before the veterans and recruits could react, the cold feeling from their throats spread to their limbs, and they fell limply to the ground, with blood flowing like a fountain from the severed carotid artery.

At the last moment of his life, they saw Asuma standing in front of them with a smile, his hands and fingers covered in blood. He took out something showing a countdown number and waved it in front of them.

Asuma threw the thing on them and left quickly.
