", you know what! Brother Dick, are you planning to use mechanical nerve implants in your arm? Chen Ziyu asked with bright eyes.

After Liu Di heard Chen Ziyu's words, he finally remembered who the person in front of him was, Chen Ziyu was nicknamed Crazy Doctor, a combination of a mechanic and a biologist, and had super high medical technology. There was a time when Liu Di's teammate was injured and the two worked together, but there was no chance to talk at that time.

"I didn't expect to meet you Lao Chen here!" Liu Di said.

"Brother Di, you're polite, I'll take a look at your arm first, if the implantation of the nervous system can't be too long."

Liu Di nodded, and removed the bandage on his arm, the cleaned arm looked even more terrifying at this time, the flesh on the arm was completely missing, there was nothing except for the bones and basic blood vessels, the back half of the entire arm was empty, and the blood was controlled in the arm, so there was no sign of flowing out.

"Brother Di, where did you put the leftover metal we used last time? I estimate that in two more hours there will be no way to fix your arm! Chen Ziyu looked at Liu Di's arm and said.

"Turn left from the front and go directly to the company, the rest of the things from last time are stored in the abandoned sewer well at the entrance of the company, password 4331." Liu Di put the bandage back around his arm again.

At this time, Liu Di knew the situation of his arm in his heart, originally he wanted to implant the nerves with metal himself, but it took a lot of time, but now Chen Ziyu is here, to be honest, Liu Di is not too worried about whether there will be any problems with his arm, Chen Ziyu is the only doctor who has come into contact with the combination of the installation of mechanical bodies and human heads, and he is also an expert in this area, so Liu Di also relaxed.

Soon Chen Ziyu returned to the car, Liu Di's company was only a few kilometers away from the logistics warehouse, and soon the group returned to the logistics warehouse.

After the disbandment, Liu Di and Chen Ziyu came to the infirmary, where the infirmary had all the equipment, so they quickly began to repair their arms.

Mechanical nerve implantation is to use this metal that can transmit human nerves to connect with the original nerve wires, and then implant human cells into it, and the mechanical nerve implantation is completed. Then there is the repair of the muscles and the sutures of the arm. The hardest part is where the nerves are connected, because if you make a mistake, you have to do it all over again.

Chen Ziyu took a scalpel and tweezers and began to repair Liu Di's arm, Liu Di's forehead has been covered with sweat, this kind of surgery to repair the arm is generally to paralyze the central nervous system and brain nerves, because this paralysis will also be risky, so Liu Di did not inject anesthetic.

The corners of Liu Di's mouth had begun to overflow with blood, he gritted his teeth tightly, the pain was like using an electric drill to penetrate his heart, but Liu Di still persevered to the end, and he fainted on the operating table after the operation.

When he woke up, Liu Di looked at the fingers and muscles of his arm, and he already had a subtle feeling, he knew that the nerves and muscles of his arm had been repaired, and then he slowly recovered.

"Brother Di, you're awake!" Chen Ziyu said with a tablet in his hand.

"Thank you, Lao Chen!"

"Thank you, Kuroko has officially invited me to join, I want to ask what you mean, can you let me join." Chen Ziyu was already nervous at this time, for fear that Liu Di would not let him join by himself.

"Now that you have decided that you want to join, I welcome you, and the rescue and medical treatment of the team will depend on you in the future." Liu Di said with a smile.

"Don't worry, as long as I'm here, I can solve the problem, by the way, I always want to ask you one thing, that is, where did you get the metal in your hand, after all, this metal can make a lot of things."

"Actually, it's under the company building, and that well is the vein of this metal, but it's already my personal property." Liu Di still told Chen Ziyu about this kind of thing, after all, this world is not the same as before the disaster, and I don't know how many survivors there are in this city, survival is a problem, who will get this kind of metal.

"I see, Brother Di, you have a good rest first, I'll go out for a while, and I'll come to see you later." Chen Ziyu said goodbye to Liu Di and came to the command office building.

"Lao Chen, why did you go to see Brother Di?" Heizi saw Chen Ziyu and said.

"Well, you don't have to go on a mission for the next two days, I need you to help me get something, I'm going to make some robots here, if there are no serious machines here, we will soon be exhausted."

Everyone in the command office building quickly got busy, and Liu Di slept for two days, in the dream Liu Di dreamed of many people, and his mind kept recalling everything that happened to him, but he didn't know why that person would say that he was involved in this disaster.

After waking up, Liu Di could already use his arm to do some basic movements, Liu Di walked to Meng Xuanchen's room, which was completely isolated when Liu Di did not wake up, and it can also be said that Meng Xuanchen had no chance to contact people outside at all.

Meng Xuanchen put down the pen in his hand after seeing Liu Di coming, and could see that Meng Xuanchen might have wanted to write something.

"Are you feeling better! Liu Di. Meng Xuanchen looked at Liu Di and said.

"It's much better, and your arm is basically left to recuperate, so are you going to go back? I'll send you a car. ”

"If I don't go back, I still have more important things to do!" Meng Xuanchen said with a smile.

"But my brother said let me get you out safely, if you don't go back to him, where are you going?"

"I'm going to the blockade on the edge of the city, and I have proof of my innocence, so you don't have to worry."

After Meng Xuanchen finished speaking, Liu Di looked at him and asked, "How do you say I'm going to send you out!" ”

"It's not very far from the nearest evacuation point, you can send someone to send me out in a moment."

Liu Di and Meng Xuanchen chatted about some other topics, and then he left the logistics warehouse, Meng Xuanchen got in the car and walked out of the gate not long after, he saw Chen Ziyu running to Liu Di from a distance with a report and said: "Brother Di, we may be in trouble this time, I saw that the third-level mutants are rushing to our side!" ”

"It's not a matter of urgency to speak slowly, you can make it clear what a third-level mutant is." Liu Di looked at Chen Ziyu, who was very anxious, and asked.

"Actually, even those infected people outside, they also evolve. Ordinary infected people are humans who have just been infected, and they don't have much attack power at that time, and after sucking the nutrients in the body of the same kind, ordinary infected people begin to evolve. Immediately after that, he evolved to a first-level mutant, and it was just a little bit of evolution. So far, I've only studied three levels of mutants. Chen Ziyu hurriedly explained to Liu Di.

"What the hell is a third-level mutant, can you see if you can see it?" Liu Di knew the seriousness of the matter at this time, and asked with a serious expression.

"I can't see it clearly, but it's about three meters high, and it looks like there may be a lot of second-level mutants and a lot of first-level mutants behind me." Chen Ziyu said very anxiously.

Liu Di knew the big picture of the matter and said, "Notify everyone immediately." Assemble at the command office building in a moment. ”

After hearing this, Chen Ziyu hurriedly ran to the command office building, while Liu Di was waiting for Tang Fan to come back at the gate.

About 15 minutes later, Tang Fan drove back to the warehouse.

"Digo. What's going on, I just heard Chen Ziyu call us from the pager and said that we were going to have a meeting. ”

"I feel something is wrong now, do you remember the warehouse we just went into? There's an infected person about three meters in there.,It's the person who doesn't have a ghost or a ghost.,At first, you said it was the test subject.。 Liu Di said.

"I remember that guy was the tallest at the time, and it was the one who smashed the door later, could it be that guy came." Tang Fan said in surprise.

"I feel that what Chen Ziyu said just now should be this guy, but I have a feeling that something is wrong." Liu Di's heart was extremely chaotic at this time, because he already felt uneasy.

"Let's go up first, I guess they'll all be there in a moment." Liu Di said after glancing at the door.

When Liu Di came upstairs, everyone had already arrived, and everyone's expressions were different.

"Chen Ziyu, let's talk about what's going on first, briefly introduce the situation this time and the situation you just saw, I need detailed content." Liu Di sat on the main seat and said.

Chen Ziyu was ready early, and after hearing Liu Di's words, he hurriedly got up and said, "Just now when I was about to go out, I saw a guy about three meters tall with the remote telescope in the warehouse. Because I've been studying infected people for so long, I can come to the definitive conclusion that the guy who is about three meters tall should be a Level 3 mutant. ”

"Mutants, what is a mutant?" The Black Shadow asked a little puzzled at this time.

"Mutants actually evolved from the infected, and the original infected were not aggressive, only infectious. However, from the evolution of infected people to mutants, they began to have obvious aggression, and this aggression increased significantly. Level 1 mutants are physically stronger and more powerful than ordinary infected people, and are not as weak as ordinary infected people. Level 2 mutants are a step more evolved than equals, their bodies are more strengthened, and their automatic speed is much faster than that of Level 1 mutants, and their strength is also very strong. Then there were the Level 3 mutants, and everything began to change further from the Level 3 mutants. As far as I know, there are only two kinds of third-level mutants that I know now, one is the kind of stupid person who is very big, and the other is the kind of mutant who has an independent mind and can command. But there are also many second-level mutants who do not have an increase in speed, but have increased their strength and height. Chen Ziyu took a sip of water from the glass and handed the information in his hand to everyone.

"From the beginning, the second-level mutants and the third-level mutants formed a watershed, and this watershed was an insurmountable chasm, like a chasm between a child and an adult. Level 3 mutants can now control both Level 1 and Level 2 mutants, but they can't control ordinary infected people. What I just saw was a Level 3 mutant, and he was heading in our direction. ”

Liu Difan looked at the information and said, "Night Shadow, you immediately send five reconnaissance drones to check, and the others immediately enter the combat readiness position." ”

Liu Di knew very well in his heart that if this thing was true, and those mutants were coming in the direction where they were, they would soon be here, just the current logistics warehouse, and there was not much combat power to resist the attack of those mutants.

Suddenly, the ghost head said: "Brother Di, someone at the door of the warehouse said that I knew you and wanted to come in and catch up with you!" ”

"Know me? You post that person's appearance on the home screen! Liu Di said puzzledly, because after he woke up, he had not seen anyone who knew him and who was looking for him.

Soon the appearance of that person appeared on the screen, and Liu Di quickly got up and said after seeing it: "Everyone go down with me, our rescuers are coming!" ”

Everyone present was puzzled, rescuers? Where are the rescuers at this time? Liu Di and the others soon came to the door of the warehouse. When I opened the warehouse entrance, I saw a truck and the person I saw on the screen just now, and after the truck drove into the warehouse, the person in the car jumped down and said, "Brother Di, I guessed that you would be here, so I came!" ”

"Yan Zhiwen, how did you guess that I was here?" Liu Di asked with a smile.

"Actually, it's not very difficult, when I went to the company to get something a few days ago, I saw someone enter the place where we were originally digging metal, I knew it was the team's car, so I found it!" Yan Zhiwen said happily with his big teeth.

"Let me introduce you to you, this is my classmate, and I am also the designer of our company's weapons and equipment department!" Before Liu Di could finish speaking, he was interrupted by the night shadow standing aside.

"Brother Di, the reconnaissance drone has sent back the photo, it is indeed a large man close to three meters, and there are many mutants, and it is still 15 kilometers away from us." Night Shadow didn't deliberately sell Guan Zi because of Yan Zhiwen's existence.

Yan Zhiwen also heard it and then said: "This time I came to defect to you, I designed a rifle in the early days of the outbreak of infection, this rifle can deal three times the damage of ordinary bullets, and the sound is greatly reduced, I experimented with this gun a few days ago, and the experiment feels very good, do you want to try it?" ”

Except for Liu Di, everyone stared at Yan Zhiwen and did not speak, and the unanimous reaction in everyone's hearts was "Is this brother sick in the brain, and the gun he said is hanging!" ”

Liu Di was surprised when he saw everyone, and then said with a smile: "I just told you that the rescue has arrived, and I am right." Suddenly, Liu Di's voice turned into a serious voice: "Everyone obeys the order, immediately go to the car and get a gun to experiment on the wall!" ”

Yan Zhiwen and Liu Di walked at the end of everyone and took each hand, everyone came to the wall, and on the other side of the street, there were still many infected people wandering around, and after aiming, Liu Di pulled the trigger in his hand.
