Finally found the staff of the duty room and the research institute, Zhang Zhiguo was a little relaxed psychologically, and he didn't even react in the face of the sudden change, and he was stunned and stunned.

After subconsciously turning his head sideways to avoid the black water, his brain seemed to be down.

The attendant of the research institute, who had mutated into a zombie, howled, jumped up and pounced on Zhang Zhiguo.

Seeing that the sharp teeth of the mutant zombie were about to gnaw at his throat, the rest of the people scattered one after another, and retreated backwards in a panic.

At the critical moment, Lu Sheng kicked Zhang Zhiguo's leg.

The sudden attack from behind him made his knees weak and he almost knelt on the ground, and Lu Sheng just took advantage of the moment when Zhang Zhiguo's body was lowered, and cut off the head of the zombie on duty with a knife.

The viscous black plasma splashed on the wall, and the head rolled to Lu Sheng's feet, and was kicked away by her at will.

The first thing Zhang Zhiguo saw when he got up was the staggering torso of the headless zombie.

The rough man who was more than one meter eight was afraid for a while, and the thin vest on his body was instantly soaked with sweat.

If someone hadn't kicked him behind him just now, he would have been gnawed to death by this mutant zombie by now!

He turned around in shock and saw the beautiful girl holding a long knife behind him, and almost knelt down on the spot to give Lu Sheng a knock.

"Thank you...... Thank you......" Zhang Zhiguo was stupid, stumbling and wanting to thank him, but he didn't know what to say, so he could only dry and repeat the word thank you.

He is a rough man with no culture, he lived by hard work before the end of the world, and he has lived by a pair of fists after the end of the world.

He has nothing to repay, so he can only silently swear in his heart that he must repay this life-saving grace!

Lu Sheng frowned slightly, put his finger to his lips and made a shushing gesture.

Zhang Zhiguo's face turned red, and he hurriedly covered his mouth, not daring to make any more sounds.

"This guy ate two colleagues, he should be resting when he was full of food and drink, and he was broken into by us." Sun Lu squatted down to check.

In addition to the headless zombie who had just been killed by Lu Sheng, there were also two sets of bloodstained security uniforms and badges in the duty room. There are still some bones with fresh shredded meat in the gap behind the sofa, which should have been thrown behind by the one in front of you.

Sun Lu wiped his hands and looked disgusted, "The quality is really poor." ”

After looking around, Sun Lu began to count the population in the duty room.

There are currently more than 30 survivors in the room, half male and half female. Because there are no ability levels required for this registration, only age and physical limitations, the types and levels of abilities for everyone present are uneven.

Many of them were eighteen or nineteen or in their early twenties, and their childish faces were full of horror. And a lot of them are support-type abilities that have less experience fighting zombies head-on.

There are more than 30 people in total, and half of them are newcomers.

"We have to find a way to get in touch with the people at the institute."

Li Kaixuan was surrounded by seven or eight young girls, and said calmly.

Good looks are a strategic resource at all times. At this critical moment, Li Kaixuan can also quickly gain everyone's trust with a handsome face.

Lu Sheng glanced at him and turned on the monitoring system in the duty room.

Soon, several monitors on the table showed unstable images one after another.

"There is no global monitoring in this duty room, we are on the fourth floor, this set of monitoring can only see a total of three floors of three, four, five and five, it should be that the institute has set up a duty room on every three floors, and is only responsible for monitoring its own area." Zhang Zhiguo came over and stared intently at the surveillance screen.

Sun Lu held her chin, "You understand it very well?" ”

"I was a security guard of the Chita Group before the end of the world, and I am most familiar with the monitoring business." Zhang Zhiguo's face turned red and he scratched his head in embarrassment.

Lu Sheng stared at the surveillance and pursed his lips to consider it.

Judging from the surveillance, the fifth floor has been completely reduced to a zombie paradise, and the people who didn't rush downstairs with them just now have been bitten and infected. In addition to their group of personnel participating in the experiment, the surveillance can also see that there are also some people wearing sterile gowns in the room on the other side of the fourth floor.

But now the identity and origin don't matter anymore, anyway, they have all become zombies.

The situation on the third floor was not much better, and both elevator entrances were blocked by zombies. If you want to go downstairs, you can only go down the stairs through the safe passage on the far right side of the corridor and see if you can rush to the first floor and run out.

"What are we going to do...... Woo woo...... "Chu Jiaojiao cried as soon as she opened her mouth, and she cried with rain without saying a word.

Li Kaixuan couldn't see a woman crying, so he immediately coaxed softly, "Don't cry, don't cry, I have a shielding magnetic field, let's go out together first, if you're lucky, maybe you won't be able to alarm these zombies." ”

"Aren't you a psychiatric?" Xu Bo asked in surprise.

"Harm, after so long in the last days, who hasn't had a secondary ability!" Li Kaixuan shook his head proudly and beckoned everyone to follow him downstairs.

Sun Lu commanded the route, and everyone moved cautiously in Li Kaixuan's shielded magnetic field.

In the safe passage to the second floor, the ever-bright lights flickered on and off, and everyone held their breath nervously, not daring to make any sound.

There were mutated zombies scattered in the safe passage, and everyone shrank in the shielded position and quietly brushed shoulders with these vengeful zombies screaming.

Li Kaixuan's mental power is limited, and it costs a lot to maintain the shielding position that envelops and tortures many people. He had barely reached a third of the way and was sweating profusely and panting.

Whenever his spirit slackened slightly, the wandering zombies would stop and face the direction of the others.

The gray-white eyeballs showed large whites of the eyes, and the fresh carrion on the body swayed with the movement. With each step, black plasma like ink splattered onto the floor.

"." Li Kaixuan cursed in a low voice, not daring to relax for a moment.

Click.

A crisp impact instantly tightened everyone's tense nerves!

A metal commemorative coin fell from the crowd to the ground, making a series of crunching noises as it rolled.

Like a stone stirring up a thousand waves, the crisp sound of landing immediately attracted the attention of all the mutated zombies in the safe passage.

"I'm sorry...... It's my lucky coin...... I was holding it in my hand, but I was so nervous just now that I accidentally fell out......" Chu Jiaojiao sobbed intermittently.

"Lucky mom! I'm going to be killed by you! Someone next to him broke down emotionally, grabbed Chu Jiaojiao's hair and yelled.

"Ho-ho!"

Several hideous and strange figures let out a roar of excitement, and the sound of chaotic footsteps poured up from far and near into the safe passage.

"it!"

Li Kaixuan didn't catch his breath nervously, and the scope of the shield instantly shrunk a part.

The smell of the new human is like a barbecue on the street during a night run, exuding a deadly temptation for the smell of a zombie with a keen sense of smell.

Just as everyone's attention was focused on the approaching zombies, a low roar suddenly came from the exit of the safe passage.

Everyone subconsciously turned their heads, and they almost lost their souls at a glance.

At the exit, several mutant zombie dogs with a length of nearly two meters drooped their fishy tongues, and their cloudy eyes rolled excitedly.

The fur on their bodies has evolved to be as sharp as bone spurs, and the rotting wounds reveal the white bones of the forest.

The long blood-red tongue trembled with excitement, and the sharp canine teeth emitted a terrifying cold light in the dim light.

"Seventh Order...... Seventh-Order Mutant Beast! Xu Bo was so frightened that his throat broke.

was caught in front and back at close range, and a huge sense of crisis was instantly enveloped in the safe passage.

"Whew!"

The roar of the zombie dog was like a knife, instantly cutting off everyone's nerves that were tense all the way.

The Survivor Alliance was in chaos in an instant, and some of them had poor endurance, and even collapsed on the ground on the spot.

The two zombie dogs struck first and pounced with a low roar.

Lu Sheng's face sank, and the long knife had already slashed cleanly.

The sharp snow blade was covered with high-voltage arcs, and the head of the dog had been cut off in the palm of his hand.

The body of the zombie dog still maintained a forward posture under the action of inertia, and was kicked by Lu Sheng into the swarming zombie group.

"What are you doing? Waiting to die? Sun Lu threw out a big fireball, and turned around and scolded with hatred.

At this time, Lu Sheng had already grabbed the blood-red long tongue of the zombie dog with his bare hands and pulled the behemoth out of the window of the corridor.

The four zombie dogs, three times and five divided by two, were wiped out by Lu Sheng's group.

The vicious dog blocking the exit was cleaned up by Lu Sheng. The rest fled in a hurry. One by one, like wild dogs on the loose, they rushed towards the door of the first floor with all their strength.

The oil bottles that affected the play all ran away, Lu Sheng narrowed her eyes, and a dazzling ball of electricity burst out from her fingertips.

The originally dim safe passage was instantly illuminated as day by the huge light that erupted from the electromagnetic cannon.

When the light dimmed, all that remained in the hallway was the meat-smelling remains.

Lu Sheng and Sun Lu adhered to the principle of not wasting when they came, dug out all the crystal nuclei, and then slowly walked out of the door on the first floor.

"Twenty-five."

As soon as the two of them appeared, they heard Meng Rui whisper, and then made a few notes in the notebook.

Xu Jing was the first to charge up, and nervously checked Lu Sheng and Sun Lu, "Are you two okay?" ”

Lu Sheng was about to speak, but Deng Ran stopped everyone's discussion with a cold face.

"Congratulations, you passed the second round of testing."

When his voice fell, the crowd was in an uproar.

"What do you mean? Is this pedal a test? ”

"Testing a vaccine is going to cost your life?"

"Rinima, Lao Tzu is not participating!"

The crowd was excited, and they all surrounded Deng Ran to express their emotions.

"I'm quitting! I did not participate! If I continue to play like this, even if the vaccine research is successful, I will not be able to enjoy it. Xu Bo's face turned pale, and he stopped Deng Ran and said angrily.

Bang.

Deng Ran calmly took out his gun and shot through Xu Bo's abuse.

"Does anyone else want to quit?" Deng Ran's expression was natural, and the muzzle of the gun shook at the crowd.

"None of the words, stats, preparing for the next stage of testing,"
