"Upstairs, upstairs." Simply shouted.

"Where's the arsenal? Did they get the gun? Cheng Jiayi shouted.

"Go upstairs!" Simply shouted again.

Cheng Jiayi ran upstairs with a gun, turned the staircase, and was faced with a black hole muzzle.

Cheng Jiayi almost didn't have time to be afraid, she leaned and fell on her back on the stairs, looked up her back, and saw that the muzzle of the gun was moving down.

Her fingers were on the trigger, and she fell still holding the gun, but the muzzle of the gun was parallel to her body.

She pulls the trigger.

"Da Da Da!" A scorching heat flew out of her face, and the gun almost jumped out of her hand. His hands were shaken as if numb. She collapsed on the stairs and saw the man's pistol fall, and the man leaned back.

Cheng Jiayi turned over and jumped up again, simply rushed up from behind, rushed to the front of her, leaned against the wall of the stairs, pointed the muzzle of the gun at the corridor in front of her, and then turned around and turned the muzzle of the gun.

Cheng Jiayi followed, only to feel that the arm holding the gun was still numb.

She glanced at the fallen man, saw the blood on his chest, and rushed into the hallway in the opposite direction of Simple.

Simply kicked open the door of a room, held a gun and posed for a strafing position, and then kicked forward to open another door, Cheng Jiayi couldn't do that, she knew she couldn't do it, so she stood at the staircase with a gun, guarding the stairs and the other half of the corridor.

A door quietly cracked out, revealing light from the inside, and Cheng Jiayi raised the muzzle of the gun.

With only a dozen paces away, she didn't know if she could shoot.

The black shadow rushed out, and Cheng Jiayi's hand had already pulled the trigger.

His arms and waist shook, and the gun fell to the ground along with the man.

After briefly inspecting all the rooms, he nodded to her as he went through Jiayi.

It is necessary to constantly replenish physical strength and keep it at the peak of physical strength.

Cheng Jiayi took out the dagger tied to her leg, half-squatted down, endured the numbness and trembling of her arm, and stabbed it into the head of the corpse at her feet.

The skull was hard, and this one didn't even open the skull, and the second knife ran everything under the eye socket.

Simply turned his head slightly, and saw Cheng Jiayi's hand reaching into his skull.

With a hint of disgust in his eyes, he kicked the door open.

Cheng Jiayi took out the crystal and held the crystal in the palm of his hand with trembling fingers.

A warm current poured into the palm of the hand, poured into the arm, the trembling of the right arm immediately stopped, the warmth came to the mind, and the warm current quickly poured into the upper body, part of it followed to the limbs, dissipated in the body, and part of it merged with the heat flow in the mind.

Cheng Jiayi grabbed the gun and stood up, and simply finished searching the second floor.

There was also the sound of gunfire outside, and Cheng Jiayi saw through the window of the stairwell that someone had fallen on the checkpoint.

"I don't recognize all of our people, how can I tell the difference?" Cheng Jiayi shouted after Simple.

Simply grab the other person's clothes and reveal the camouflage uniform inside.

Above the stairs, there is a short section of ladder to climb the wall, take a brief look, fly downstairs, Cheng Jiayi didn't know why he ran into the arsenal, and saw that he was holding a big bag, throwing some things in the arsenal in one go, and then ran out and turned upstairs.

Cheng Jiayi stood downstairs stunned for a while, she felt simple disgust with her for no reason.

Because she cut off the man's head to take the crystal?

Cheng Jiayi didn't want to explain, she didn't ask, and she didn't need to explain, but she felt very uncomfortable.

She stood in the middle of the corpses on the ground, and saw Simple jump up the ladder, push open the small door above and disappear to the roof.

What is she going to do?

The small door above suddenly darkened, and a simple face appeared: "Come up!" ”

Cheng Jiayi glanced at it, and jumped up the ladder with the gun behind him as he ran.

As soon as his head appeared, Cheng Jiayi was startled, their building was a second floor, not far ahead, and there was a slightly taller building.

"Hurry up, come here!" Simply shouting without looking back, he was already lying down on the roof, holding a gun at the slightly higher building opposite.

Cheng Jiayi ran over at the risk of waisting, "Get down!" With a simple shout, followed by the sound of bullets in his ears, Cheng Jiayi pounced forward, and saw a head exposed on the roof of the opposite side leaning back and disappearing.

Her heart thumped, and she felt like she was on the battlefield.

"Don't let people come up!" Simple still took the gun and aim, and commanded.

Cheng Jiayi turned her head to look at the small hole she came up from, and then turned her head to see several checkpoints behind her that were almost as high as the side of this building. If there were any more people on the checkpoint......

There were people at the checkpoint, holding guns and firing frantically downward, and the sound of gunfire was deafening. There were gunshots behind him, and Cheng Jiayi lay on the roof and looked around.

In the line of sight, I could only see the place higher than myself, the empty checkpoint, the strafing checkpoint, and the silence on the roof of the opposite building.

What she heard in her ears was the sound of a rain of bullets, and the sound of all the guns in her ears was just a "thump" sound, breaking, continuous, and screaming and screaming.

She suddenly realized that she was useless in such a battle.

On the battlefield of thermal weapons, fists, feet, clubs, and even sharp knives are of no use.

She subconsciously pointed the muzzle of the gun at the small hole in the roof, but she wanted to poke her head out to see the shooting on the ground, and she gradually heard that most of the shots were from the height to the bottom, and she suddenly remembered the weapons they were carrying.

All those are left to the people on the checkpoints?

"Go down." Simple suddenly ran past him, poked his head in front of the entrance of the cave, and suddenly grabbed the floor slab and ran down. Cheng Jiayi didn't have such good skills, so she got up and took a look at the ladder first, and then turned around step by step.

When she got down, she remembered that the gun had been dropped on the roof, and she glanced at the corpse-strewn staircase, and found the iron rod she had left aside in the corridor.

Simple had already run to the gate, turned around and said impatiently "keep up". Cheng Jiayi has never been so disgusted in battle, and she has the idea of hiding in the building and not going out for a while.

But she also just thought about it, and followed closely behind Simple.

Turning around the building, she saw the corpses all over the place, she didn't know where to tell that they were safe now, and no one would snipe at the window of the opposite building?

She followed behind Jane, simply sticking to the wall of the building, standing down at the corner, gesturing backwards, Cheng Jiayi subconsciously turned around, there was no one behind her, and suddenly this gesture was for her, but the embarrassing thing was that she couldn't understand it at all.

Simply exposed one eye slightly, Cheng Jiayi leaned against the wall, and did not dare to make any abrupt movements.

On the opposite side is a large row of open spaces, far in front of which there is some greenery, and then a fence.

If there are people hidden in the greenery, she and Simple are simply the most obvious targets.

Jian Jian suddenly stood back and said: "About one hundred and fifty meters ahead, there is a garage, we rush over, your gun is thrown down, the speed must be fast." ”
