Just as the laboratory was slowly ascending, Professor Li's mobile phone suddenly rang, and everyone present instantly looked at Professor Li.

When Professor Li took out his mobile phone and looked at the screen, his expression instantly became serious.

"Professor Li, has something happened?" Wang Lung immediately noticed the change in Li Xiangbin's expression.

I saw Dr. Li's mobile phone showing a call from Wei Zhongtian.

"Who's the Professor?" Wang Lung asked Li Xiangbin.

"I'll tell you later, I'll answer the phone first." After speaking, Li Xiangbin pressed the connect button.

An anxious voice of a middle-aged man came from the other end of the phone, "Teacher, I'm Wei Zhongtian..."

Li Xiangbin walked behind the mutant dog while listening to the phone, deliberately avoiding the others. After a while, he finished listening to the call and walked to Wang Lung's side.

"Didn't I tell you in the lab before that the mutant dog has a control chip in its brain, which was jointly developed by me and my two students, this Wei Zhongtian is one of them, and the other is called Gu Xiaoyun is also Wei Zhongtian's wife." Li Xiangbin continued to introduce to Wang Long, "The husband and wife are my proudest protégés and the top scientists in the field of electronic engineering. ”

"Then did this Wei Zhongtian say something to you just now?" Wang Lung asked.

"Come here, I'll tell you something." Li Xiangbin beckoned Wang Lung to come over and speak.

Li Xiangbin whispered something in Wang Lung's ear.

After 10 minutes...

The huge laboratory rises to the highest level of the floor.

"Lab reaches the top floor" The voice of an artificial intelligence system can be heard in the room.

The door of the laboratory opened, and what appeared to everyone was no longer a white passage, but an empty platform, and the warm sunlight shining on the platform gave people a comfortable feeling. Suddenly, there was a burst of gunfire outside.

"Oh no, Lieutenant Colonel Maggie they're fighting." Jia Xingguo shouted anxiously.

"Let's go out and support Maggie." Professor Li Xiangbin picked up the controller of the mutant dog and ordered everyone to get out quickly.

5 minutes ago...

On the staircase from the basement floor to the first floor, forty people were crammed into a narrow space. Only the first ten people had guns in their hands, and the rest were some unarmed scientific researchers. Along the way, they didn't use weapons, and only relied on Li Siqiang to destroy more than 10 living corpses with his bare hands.

"Sister Maggie only needs to open this door, and we will go to the first floor, but I don't know how many living corpses there are behind the door." Li Siqiang said to Wang Meiqi, who was on guard with a pistol next to him.

"Da Han, you will listen to my orders in a while, and I will open the door when I ask you to open the door. If there aren't many living corpses on the other side of the door, you'll be left to deal with them. Wang Meiqi said to Li Siqiang.

"It's okay, Sister Meiqi, all the soldiers are ready to fight, all the assault rifles are bayonets, in case the bullets are finished covering and reloading, it's really too late to prepare for hand-to-hand combat with the living corpses, the target's head, is it clear?" Li Siqiang gave an order to the soldiers behind him.

"Clear." Behind him, voices replying to him came one after another.

"Very good, although my father is not here, but since I am the commander of this team, please believe me and please cooperate with me, these people behind you are the hope of the Federation, and may even be the hope of all mankind, and they will die in front of them." After speaking, Wang Meiqi bowed deeply to the nine people holding weapons behind her.

At this moment, all the soldiers felt Wang Meiqi's sincerity and the importance of her mission, and they were all ready to face the next fierce battle.

"Open the door!" Wang Meiqi gave the order to break through.

Li Siqiang, who received the order, held the doorknob in his hand and pushed it hard, and the door at the staircase opened. The moment the door opened, the light entered the staircase, and everyone's expressions were noticeably nervous.

The 10 fighters led by Wang Meiqi rushed out first, followed by the scientific researchers in white clothes, and when they all rushed out, the sight in front of them made all of them tingle their scalps. The hall on the first floor was littered with mutilated corpses and blood stains all over the floor. Not far away, more than a dozen living corpses were sitting on the ground, enjoying a delicious meal.

"I'll it, it's purgatory on earth." Li Siqiang looked at the scene in front of him, and a chill ran down his spine, and a cold sweat appeared on his head.

Wang Meiqi looked at the scene outside the window, gently tapped Li Siqiang's shoulder with her index finger and said, "It's a big mistake, it's purgatory on earth outside." Then she pointed out the window.

Everyone present looked in the direction of Wang Meiqi's guidance, and the scene outside the window at this time could no longer be described as terrifying, and the square outside was densely packed with living corpses in action, and the number was at least five hundred. These more than 500 living corpses are all dressed in soldiers' clothes, and some of them are carrying assault rifles on their bodies, you can imagine how tragic a fierce battle took place in the square before, even if there are weapons in their hands, they are still swallowed up by the group of living corpses with superior numbers, the reality is really cruel.

"Don't even look at it, let's find a way to get rid of the living corpses in the hall first." Maggie Wang said to everyone.

Li Siqiang gently placed the Gatling machine gun on the ground, picked up a chair from the ground next to it, and walked towards the more than a dozen living corpses in the hall.

The chair dragged on the ground and made a "sizzle" sound. The living corpses in the hall turned their heads slowly, staring at Li Siqiang with blank eyes, and let out a low moan.

When Li Siqiang dragged a chair to the first living corpse sitting on the ground, he looked at the living corpse for a few seconds. Then I saw Li Siqiang lift the chair in his hand high and smash it down violently, and in an instant, the living corpse's brain collapsed and fell to the ground, twitching a few times, completely dead.

After seeing their kind being stoned to death by the tall human in front of them, all the living corpses in the hall instantly turned into angry roars, and they all immediately stood up.

The scene in front of him made Li Siqiang shout: "It's not good, everyone hurry up and retreat to the stairwell." ”

Then Li Siqiang quickly retreated, picked up the Gatling machine gun on the ground, raised it, and prepared to strafe. Wang Meiqi also stood beside Li Siqiang with a pistol, and then several soldiers also stood up with assault rifles.

"Sister, you take the scientific researchers into the stairwell, it's too dangerous here to use you, and the living corpses outside will definitely break through the window in a while." Li Siqiang blocked Wang Meiqi next to him with his left hand and pushed back.

"I don't want it, I'm going to fight with everyone!" Wang Meiqi, who was unwilling, looked at Li Siqiang and said.

"Sister, your pistol can only protect itself, killing a living corpse is not practical, but will increase unnecessary trouble." Li Siqiang looked at Wang Meiqi with firm eyes.

"You..." Wang Meiqi couldn't say anything angry at this moment. But she knew very well that Li Siqiang was there to protect her.

"The private obeys the order, and the lieutenant colonel will be dragged down for me." Li Siqiang said to the two soldiers on the right.

As soon as Li Siqiang's words fell, two privates came up, and one of them dragged Wang Meiqi down.

"Li Siqiang, you bastard..."Wang Meiqi scolded loudly.

After a short half a minute, more than a dozen living corpses opposite Li Siqiang had already stood up, raising their hands and slowly swaying towards him, roaring angrily as they walked.

"Are you all ready?" Li Siqiang asked the soldiers behind him.

"All set!" The soldiers replied in unison.

"Very well, listen to my orders and prepare to shoot. Remember that when the gunshots go off, the living corpses outside will break through the windows, and we must resist them. If we were forced back into the stairwell, we wouldn't be able to get out, and in order to be fast, accurate, and save ammo, we targeted the heads of living corpses, using the burst fire mode, and trying not to waste ammo. When changing bullets, everyone covers each other, and when the living corpse gets close, they fight hand-to-hand with bayonets. Li Siqiang turned his head and smiled slightly at the soldiers, and then shouted, "The brave are fearless!" Choose your target freely and fire! ”

At this moment, a burst of automatic rifle gunfire suddenly rang out, worthy of the soldiers led by Wang Long, even the privates' marksmanship was very accurate, and within a few seconds, more than a dozen living corpses in front of him were all headshot and fell to the ground, and the Gatling in Li Siqiang's hand did not shoot. Soldiers, you look at me, I look at you, smiling at each other.

Just as they were rejoicing for each other, all of a sudden all the glass windows on the left side of the hall shattered, and from outside the windows there were living corpses pouring in and falling to the ground. Before these living corpses could get up, something even more terrifying happened. The glass door of the hall was crushed by the hordes of living corpses outside, and hundreds of living corpses outside the square kept pouring into the hall.

"Full fire, block them!" Li Siqiang gave the order to shoot.

For a while, the whole hall resounded with a roaring gunshot, why is it a roar, because the Gatling machine gun in Li Siqiang's hand began to strafe. The terrifying rate of fire and lethality of the Gatling machine gun instantly impressed everyone present. The group of living corpses opposite them was swept down again and again by Gatling in Li Siqiang's hands, stood up and was swept down again and again, until all the guns and holes were completely dead from all over the body. After a few short seconds, it was already difficult to see the living corpses on the other side, because only a thick layer of blood mist could be seen in front of them. But what is certain is that the living corpses outside the door are still pouring in.

After a burst of strafing, Li Siqiang's Gatling was out of ammunition, and he threw the machine gun to the ground and then raised the assault rifle at his waist. Even without the suppression of heavy weapons, all the living people present still did not give up hope of survival.

After a few moments, the gunfire grew weaker and weaker, until the last few pistol shots were heard, and Maggie Wang finished her last bullet.

"We don't have a chance, Dahan." Wang Meiqi pressed one hand on Li Siqiang's shoulder and comforted.

Li Siqiang smiled at Wang Meiqi, and then shouted to the soldiers behind him: "Bayonet hand-to-hand combat, death must die in front of scientific researchers, and death is worthy of General Wang Long's expectations of us." ”
