mutant biological system

()Zhang Ziying was distracted for the first time while sitting on the roof of the building, her mind was in a mess.

"Why am I so confused? There is no blood on the ground. Even if I jump from the height of the sixth floor, nothing will happen. That guy was so seriously injured by the explosion that he didn't die. How could he be hit by a few shotguns from my bullet and fall?" He died instantly, not to mention wearing a full set of sniper protective clothing. How could he be so careless and be fooled?"

While Zhang Ziying was feeling remorseful, she didn't notice that there were some monsters in the city center in the distance, moving in groups of three or five, moving towards here.

When a series of gunshots sounded nearby.

Zhang Ziying just came back to her senses, picked up the sniper rifle and took a look. She took a breath of air. The ultra-infrared detector showed dense red dots.

"The monster is coming!" he yelled loudly into the miniature microphone on his shoulder.

At the same time, the sniper rifle also opened fire, blowing the head off an E-class monster.

"Is there any mistake? We're here for a sneak attack at night." Xu Qianming muttered and got up.

"The number is really quite large." Hei Tianyuan looked outside with an electronic telescope.

Without saying a word, Zhang Yifei stood guard on the stairs with a power hammer. Xu Qianming set up a sniper rifle and started shooting.

Zheng Yaozu came to the window and fired a mortar with heavy firepower, aiming at the place where the monsters were concentrated below, and it was a bombardment.

Judging from the surrounding situation, the monsters seemed to have launched a surprise attack on all the firepower points guarding the central area of ​​the city, and the number could really be described as massive.

Although everyone tried their best to shoot, there were too many monsters and they could not be suppressed.

Xue Yaqi stood guard at the door and began to fire at the bottom of the stairs. It seemed that the monster had begun to come up the stairs.

Sure enough, it didn't take long before the sound of the power hammer's attack was heard.

Hei Tianyuan also picked up the knife and walked out of the room to help Zhang Yifei guard the stairs on the last floor. With Xue Yaqi shooting at such a close range, the problem was not big for the time being.

After all, the width of the stairs is limited, so the monsters can't rush up all at once, they can only line up to get beaten up.

The battle was fierce and lasted for an hour.

"Captain, I'm almost out of mortar shells, I have the last box left." Zheng Yaozu shouted towards the stairs.

"Save it for tomorrow's attack." Hei Tianyuan slashed a monster to the ground with his sword and shouted with all his strength.

Zheng Yaozu picked up an explosion-proof blaster, walked out of the room, and shot with Xue Yaqi at the crowded monsters on the stairs below.

Some monsters can climb and jump, and most monsters, especially E-level monsters, can jump a considerable distance.

Zhang Yifei and Hei Tianyuan gradually retreated.

Xu Qianming was shooting when he suddenly heard some movement below. He lowered his head and saw the densely packed monsters climbing up along the surface of the building. Occasionally, half of them would only fall down, but most of them climbed quite well.

"The monster climbed up from outside the building." Xu Qianming shouted.

Zhang Ziying on the roof had already used special sniper bullets, the kind that hit Xu Qianming before.

Although it cannot penetrate the skin of most monsters, it will still hurt when it is knocked down. Once it hurts, it will let go and fall downstairs.

Every time Zhang Ziying shoots, she can kill a bunch of monsters.

"Oops, there are still three Tiannu Sanhua left." Zhang Ziying has a lot of special bullets, but the quantity of each type is not very large.

"It's no longer possible. I can't hold it anymore. If the monster climbs to the top of the building and attacks it from above, it will be in trouble." Zhang Ziying ran into the house and shot down from the window with a sniper rifle while facing the others.

"It's time for Nirvana!" Hei Tianyuan was also anxious.

Now the place in front of the door is completely defended by him and Zhang Yifei. Zheng Yaozu and Xue Yaqi have already entered the house to shoot the monsters climbing up the stairs. If the roof of the building is lost again and the monsters capture it from upstairs, the trouble will be really big.

"Yeah." Xu Qianming stood up and moved his body.

"Hurry up and shoot! What are you doing?" Zhang Ziying glanced at Xu Qianming dissatisfied.

"Leave the roof to me."

Xu Qianming left the room with his sniper rifle and walked up to the roof.

"idiot!"

Zhang Ziying whispered and continued to shoot downstairs.

Xu Qianming walked to the top of the building, the blue light in his hand lit up, and the mutated bodyguard creature appeared next to him.

"Seal the entrance to the bottom."

"Yes, Master." The mutated bodyguard creature looked around.

There was a small utility room on the roof of the building, and he dismantled the small utility room in a few steps, and then carried it to the downward corridor.

Then the entire utility room was blocked at the entrance of the corridor, completely sealing off the downward corridor.

"What's the noise upstairs?" Xue Yaqi was a little nervous.

After all, she had been almost killed by monsters twice. Now seeing the dense monsters, she felt a little scared.

"I'll go to the roof to help Xu Qianming." Zhang Ziying held up the sniper rifle and opened the door leading upstairs.

He stared blankly at the blocked corridor outside the door.

Then silently, he came back with the gun and continued shooting from the window.

"What happened upstairs?" Xue Yaqi asked.

"The corridor upstairs is blocked. I can't go up or down." Zhang Ziying replied expressionlessly.

"What about Xu Qianming?"

"Don't worry about this idiot, this idiot!" Although Zhang Ziying said "idiot", she had already bit her lip with her teeth until it bled.

When Xue Yaqi saw it, she didn't ask any more questions, turned around and continued shooting downwards.

Xu Qianming was on the roof of the building, throwing aside the sniper rifle, pulling out the hunting knife on his back, and waiting quietly.

The mutated bodyguard creature activated camouflage mode and stood guard in front of the corridor entrance.

Soon, except for the north side of the building facing the central city, monsters climbed up on the other three sides.

Seeing Xu Qianming standing on the roof alone with a hunting knife, the monsters that climbed up all swarmed towards Xu Qianming.

It got dark two hours later.

There were more than fifty new hunter teams that entered the city from the outskirts of the satellite city. The monsters that besieged each firepower point began to retreat under the fierce attack.

Monster corpses are everywhere around the firepower point buildings.

"Ouch..." A monster's head was completely split in half by Xu Qianming with a hunting knife.

"Huh, you are really underestimated. There is not even a single D-level monster." Xu Qianming looked at the piles of monster corpses around him.

The mutated bodyguard creature devoured these corpses and pushed a large number of corpses downstairs while eating.

"Qian Ming, are you okay?" Hei Tianyuan's voice came from the corridor downstairs.

"I'm fine." Xu Qianming shouted.

"I'll remove the obstacle, Qian Ming, stay away." As Zhang Yifei's voice came out, the small utility room blocking the stairway began to shake.

A blue light flashed in Xu Qianming's hand, and the mutated bodyguards and a group of monster corpses were transferred to the void world.

Putting the hunting knife on his back, Xu Qianming sat on the ground covered in the monster's blood.

"Boom -" Zhang Yifei and Hei Tianyuan pushed the grocery room out.

The members of the team rushed up and looked at the monsters on the roof and Xu Qianming sitting leisurely on the ground.

"You're really good at it." Hei Tianyuan came over and pulled Xu Qianming up.

"It's just a joke, but I really need to go take a nap and rest." Xu Qianming patted Hei Tianyuan on the shoulder and walked downstairs.

Zhang Ziying picked up Xu Qianming's sniper rifle from the ground, touched the barrel and looked at the ground.

"You never used a sniper rifle at all, did you always use a hunting knife?" He glanced at Xu Qianming's back as he came downstairs with doubtful eyes.

Due to the monster's attack at night, the teams stationed at each firepower point suffered heavy losses.

Many teams chose to withdraw from the mission due to the casualties of more than half of their personnel.

Even seven teams with seven firepower points were wiped out.

There is no priority in the monster's attacks. They are all over the place and attack in an all-round way.

Xu Qianming's Mad Lion Squad was one of the three squads that had no attrition in last night's battle. It was also the smallest squad and the one with no advantageous terrain.

The other two teams, a sixteen-man team, were guarding the vault basement and exited an entrance. The surrounding walls were made of super alloy.

The other team's defensive position was also very high, but the team had forty members and a lot of firepower and heavy weapons. They barely managed to hold on, but more than a dozen people were injured.

In comparison, the six members of the Mad Lion Team were holding the top of the building, and there were no wounded who could not fight, which was simply a miracle.

Due to the loss of the team that entered in the early stage, and the serious consumption of remaining ammunition.

The military postponed the attack time and prepared to launch the attack in the afternoon after another group of hunter teams arrived and a batch of supplies were airdropped.

Xu Qianming's team is now in a small building, and everyone is sleeping.

There is also a small team in the small building responsible for security.
