Just when everyone was chatting, there were three knocks on the door, and everyone's hearts rose to their throats, Xu Yihuan and Cao Boyi clenched their weapons and prepared to open the door.

As soon as the two opened the door, they saw a person with a bloody face, Xu Yihuan and Cao Boyi thought it was a zombie and clenched the baton and smashed it down, only to see a beautiful dodge of the "zombie", one after another, and finally pushed the two away with two palms.

"Li Nanhui, the blood on his face is from the tall muscular zombie, and I solved it, is there any paper?" Except for the original Cao Boyi, the rest of the people present didn't know Li Nanhui, but we knew the tall zombies, and this guy actually solved the tall zombies, it's not simple......

A few minutes later, Li Nanhui cleaned up, "Isn't this school grass?" A girl said.

Li Nanhui smiled embarrassedly, revealing a parenthesis, "Handsome guy, how did you get that tall zombie, that thing has been bothering us for a long time." I asked.

"My family has basically been in the army for generations, and I have also learned some moves, that guy is indeed more difficult than ordinary zombies." Li Nanhui said modestly.

"Hey! Lao Chen, didn't you see it, that Li Nanhui is handsome, dodging and fighting, slashing and splitting, haha, I don't know how to describe it, like a martial arts star, the old handsome, the first time I saw that tall zombie deflated, and he was killed. Cao Boyi blew Li Nanhui's rainbow fart.

"Don't be so happy, if you know that there are undercover agents among us who provide Li Peng and others with my whereabouts and information, can you still laugh?" Jiang Haochuan, who had been silent, spoke.

"Undercover? This is not a police movie, we are just a group of innocent and lovely students, why are there undercover agents? Zhang Xing asked angrily.

"Otherwise, why can they know our whereabouts every time, why is Chen Yu hacked, Yan Xinyu is still trapped in the laboratory, we are attacked every time, and there is such a thing as an undercover agent among us...... It was Li Peng who told me, I met him, to be honest, although he is an enemy, but this is not like a lie, and what we encountered also shows that it is true. Jiang Haochuan continued.

I fell into deep thought, thinking that it really doesn't rule out the possibility of an undercover agent, but why? There's nothing to go undercover, I don't understand the purpose.

"Huh! Xiao Muyi, what are you doing sneakily? Zhang Xing looked angrily at Xiao Muyi in the corner.

"I'm studying the surveillance on this wall, and there's also surveillance on the wall of the studio, and...... It seems to be moving. Xiao Muyi said.

"But I just saw what you seemed to be saying to this monitor, what were you just muttering? Betraying us? Give Du Chengpeng their whereabouts to leak? Zhang Xing said angrily.

"Don't spew blood! Classmates who have been in business for so long, there are people to accompany you in your actions along the way, even if it is me who is undercover, how can I pass on information? Xiao Muyi said a little angrily.

"Who knows what you do, you might throw a small note on the ground, send a message to your phone, talk to the surveillance or something." Zhang Xing said angrily.

"Are you sick? What is my reason for doing this? What do I get? Where have I offended you? At this time, Xiao Muyi no longer had the usual appearance of a quiet boy, and yelled at Zhang Xing.

"Stop arguing! This is not the time for a split, we should think about what to do next. Chen Yu said.

At that moment, the door was slammed, "It's a group of corpses!" I dragged my half-injured body up, "What should I do?" Cao Boyi asked.

"Kill it." Li Nanhui said lightly.

"Dude, we're not you, so good." Cao Boyi complained.

"You guys, the wall here is empty, where can you open it, go to the balcony and hide, I'm here to make a noise and attract zombies." Yan Xinyu on the surveillance spoke, and it turned out that he had noticed.

I made an ok gesture, yes, I noticed it when I came to the studio to help a teacher record a class dubbing, the wall of the recording studio can be opened, and the outside is a balcony, you can hide for a while, and the zombies will not find out.

The crowd began to go to the balcony one by one, and when everyone went to the balcony, the crowd was crowded, and it felt like everyone was going to be squeezed downstairs.

Suddenly, the person on the left side of the balcony suddenly sat back and found that the wall on the left had collapsed, "There's an elevator!" The student on the left said in surprise.

"Okay, everyone goes down one after another, and the one who goes down first will cover well." Chen Yu said.

Yan Xinyu outside began to play music, the door of the recording studio couldn't hold on, the zombies were gradually attracted by the music, we entered the elevator in waves, there was only one button in the elevator, and the destination was very clear, no need to choose.

When everyone went down, they looked around and saw that it was supposed to be a cave, probably an abandoned mine or something.

"Is there a place like this in the school?" Cao Boyi sighed.

"It's not surprising, there are so many strange secret rooms, and Lao Yan's laboratory." Chen Yu said.

"It's not because of some undercover adult." Zhang Xing said angrily.

"You're endless! Okay, I'll go, you're satisfied. After Xiao Muyi finished speaking, he walked directly into the unknown depths.

"Steward Zhang, what do you say you are competing with him! Brother Sao is calmer, it's too dangerous for him to go alone, and it's not necessarily who the undercover agent is, we shouldn't be suspicious of each other, we have come a long way. Chen Yu said.

Zhang Xing thought for a while, "Also, I'm too impulsive, I always think that I can't put everyone in danger, but I wronged Brother Sao without analysis, it's my fault, I'll chase him." Zhang Xing said angrily.

"I'll go with you, this is unknown to us, I also want to explore, Brother Sao may not take that path." Chen Yu said.

"Okay, I'll go find Brother Sao too, after all, Brother Sao is my 'girlfriend', haha, just kidding, Brother Hui, stay with me, protect me." Cao Boyi said.

"Yes, I just found a weapon to handy." Li Nanhui found a knife from the car next to him, not long or short, just right.

"I'll go too, I'm also responsible for this." Jiang Haochuan said.

"I'll go too, it's been a long time since I've been active." Jian Dan said.

"Okay, then let's do it, Brother Nan Hui, you should know how to use the knife technique, teach me two tricks? It just so happened that I got a nice knife too. Chen Yu said.

"Okay, then you have a good look." After that, Li Nanhui demonstrated a set of knife techniques that are not flashy but very practical, and the knife is deadly, Chen Yu is talented, and he will follow it two or three times.

"You're very talented, have you practiced?" Li Nanhui asked.

"I've practiced some martial arts, empty-handed, clubbed, and knife-like skills." Chen Yu said.

"Then you should be pretty skilled, do you know how to shoot?" Li Nanhui asked meaningfully.

Chen Yu's heart was shocked, why did he ask me if I could shoot, did he know that I had a gun? But I didn't show it to anyone, so it was just a coincidence......

"I used to be in Hawaii with my dad...... Hahaha, I'm not Conan, I haven't learned to shoot, I can't use a gun, I'm afraid the recoil will dislocate me. Chen Yu dodged jokingly.

"Oh, that's a pity, this kind of place, it's a bit old, maybe there will be guns." Li Nanhui muttered.

"Don't say much, it's time for Brother Sao to go away, everyone, let's go." Chen Yu said.

Yan Xinyu's side.

"Everyone should be out of trouble, and I should continue searching." Yan Xinyu said.

Yan Xinyu walked out of the patient room, continued to search, and found a foreign clothing room, after entering, he found that it was full of similar protective clothing and the like, Yan Xinyu walked to a desk and found a note, which was as follows:

Why is this happening? It's out of control, it's out of control, I didn't agree to do this experiment in the first place, here's ...... It's slowly falling, and it's also outside, and the guys here have also suffered from radiation, it's disgusting, I've been touched by the body fluids of these guys, and there seems to be something wrong with my body, sure enough, do you still want to wear protective clothing, I'm really an incompetent researcher, I don't usually like to wear it, and now I'm guilty, wait, if these guys mutate! That...... Those things! Those things should have mutated too! These places can't trap them at all, it's over, it's all over! Oh no, here they are! Stranger reading this, here are my last words that I wrote urgently, this institute contains the causes and consequences of the outbreak of the virus in this area, as well as some valuable experimental samples, report, you must take it out, this may save all mankind, and beware of something here! This could kill you! I can't make it alive, those guys are here, and besides, be sure to wear a hazmat suit, kill with H-liquid, don't get touched by liquid, and also, there's a revolver and seven rounds of ammunition in the drawer of this desk for you as a gift, and ......

It's gone here, all that's left is blood, and it looks like that guy should ..... There was also a Gleen in the bottom right corner of the note, which must have been the guy's name, and there were guns and bullets in this drawer.

"Huh? There's also a card, I don't know what it's for, it should be useful, take it first. Yan Xinyu said.

Yan Xinyu picked out a protective suit and put it on, but this protective clothing is really uncomfortable to wear, no wonder that guy doesn't like to wear it.

But...... What are the things that the guy is talking about, and this guy's body doesn't seem to be here, is it something terrible?

Yan Xinyu continued to search with questions, there was a very sharp dagger in the other drawer, and there was a tape-like thing, but there was no projection machine here, let's load it first.

"Aren't the zombies here going to be killed with H liquid, why did this guy give me the revolver, this dagger was also left to me by him, these weapons shouldn't be able to kill the zombies here, isn't it useful?" Yan Xinyu was still confused.

Yan Xinyu turned on his mobile phone and looked through the monitoring, trying to see if he could see Chen Yu and them, but he didn't know that Chen Yu and they had already arrived in an underground mine, how could there be surveillance, but when Yan Xinyu was transferred to a classroom, he was startled, only to see that this classroom was densely packed with zombies, which seemed to be artificially controlled here, and there were at least hundreds of them in a classroom.

"Our school...... There won't be any perverted zombies. Yan Xinyu took out the walkie-talkie given by Du Chengpeng before, "Du Chengpeng, Du Chengpeng, are you there?" ”

"You just call your teacher's name like that, doll, although I haven't taught you, I'm your director" Du Chengpeng's magnetic voice came from the walkie-talkie.

"Director Du~" Yan Xinyu shouted angrily, "What the hell is here, I don't understand it anymore." ”

"Don't worry, doll, some mysteries have to be found out by yourself to have fun, you better go play by yourself, by the way, don't worry about your little friends, they went to another place, at present, it's still very safe, it's just that your people are a little contradictory haha, one of your classmates ran away from home haha."

"Who? Hey, hey! Back! There was no sound on the other end, "Damn, another place...... Everyone, you must be good! Yan Xinyu said.

At this time, the mysterious man muttered in front of the monitor: "Don't panic, kid, take your time, you will find that there is a hole here, and I will continue to observe you." ”
