Entering the Seoul University subway station, they kept absolute silence this time. They walked through the zombies and came to the ground.

There were some scattered zombies on the campus of Seoul University. They also continued their previous practice. Without disturbing these zombies, they came directly to the door of the laboratory mentioned by Han Youlin.

The laboratory is built underground, the entrance is in the experimental building, and there is a separate elevator leading to the laboratory.

According to Han Youlin, the power supply of the laboratory is independent, and the elevator can still be used, so Guo Lingfeng is ready to press the elevator button.

Han Youlin stopped him and said with a smile, "not everyone can use this elevator!"

Guo Lingfeng was a little confused. Therefore, Han Youlin walked to the elevator, stretched out her left hand and pressed it on the wall next to her. She just heard a "click", and a panel suddenly appeared on the wall.

Han Youlin approached her face and saw a red light sweeping her beautiful eyes. A line of words appeared on the panel: "recognition error, no entry!"

Han Youlin was stunned, then tried again, but she still couldn't. She couldn't help but wonder, "what's the matter? How can my iris recognition be wrong?"

Han Youqi went to the front and said, "let me have a try?"

She did the same action as Han Youlin just now. This time, the elevator door opened.

Han Youlin said strangely, "what's the matter? Why my iris recognition authorization failed, but yours is OK?"

Han Youqi stretched out her tongue and said with a smile, "how do I know? Who knows what happened in this laboratory after we left Seoul?"

Han Youlin thought for a moment and said, "that's what you said! Anyway, it's already open. Let's go in!"

Guo Lingfeng couldn't help sighing: "this time it's a rising posture. I've only seen it in the film before. I didn't expect to see iris recognition with my own eyes!"

After entering the lift lift, Guo Lingfeng looked at the elevator panel only two buttons on the floor above, one was "1", the other was "B18", and he couldn't make complaints about it.

It's understandable that the laboratory is built deeper, but why does it have to be this floor?

Lower 18th floor? Why didn't your mother just say it was 18 layers of hell?

Did the architect read too many ancient Chinese myths?

I don't know if those people who did research in this laboratory felt that there were any problems with Feng Shui here. Would some supernatural events often occur?

Han Youlin didn't know his wishful thinking. She raised her hand and pressed the button of "B18".

The elevator ran very fast. They came to the lower 18th floor, the laboratory floor, in less than half a minute.

As soon as the elevator door opened, there was only a short corridor in front of me. The walls of the corridor were made of steel plates. There is a gate at the end of the corridor, which seems to be a thick iron gate.

Han Youqi went to the door, verified her identity again, and finally opened the iron door ten centimeters thick.

This time I finally entered the laboratory. The space here is so high and large. Guo Lingfeng is afraid that it will not be smaller than a standard football field, and the ceiling is at least 30 meters.

It definitely costs a lot of money to establish such a laboratory. If it is not for cooperation with the government, how can it have such financial resources?

The iron door closed automatically and made a dull sound of "Dong".

Han Youlin said, "now we should be safe!"

Guo Lingfeng said with a smile: "not necessarily. I think you'd better not relax your vigilance so soon. I'll go and have a look first, but don't suddenly jump out of a zombie later!"

Han Youqi said with a smile, "even if a zombie suddenly comes out, I'm not afraid. It's not a small idea to destroy them with Brother Guo?"

Guo Lingfeng smiled proudly and said, "that's a zombie. I'll kill him in seconds!"

As soon as the voice fell, I heard a roar in the distance, and a zombie with a height of more than two meters and five jumped out.

"T3?" Guo Lingfeng couldn't help but get a big head. "I'm in a groove! Don't you play with me like this? I just said to kill the zombie in seconds. Will you really get one for me?"

The Han sisters had a deep understanding of the horror of T3. They rushed behind Guo Lingfeng.

Guo Lingfeng quickly took out the RPG from his backpack and loaded it with a rocket. Looking at the approaching T3 step by step, he couldn't help smiling: "I used to have Tucson broken, but I would fight with you. This time I won't be so stupid!"

After he aimed, he pulled the trigger decisively, and the rocket "whew" flew out, directly hit T3's chest and blew the behemoth into pieces.

Although the explosion was very strong, the Han sisters shrank behind Guo Lingfeng and didn't feel any impact.

After solving this T3, Guo Lingfeng ignored the smoke of gunpowder and took an automatic rifle and looked around, which relieved him.

"Well, there are no other living creatures in this laboratory except the three of us!"

Originally, Guo Lingfeng thought there would be other zombies here, but he found nothing. The whole laboratory, including the living area, was empty.

But they were going to use it as a base in Seoul. There were no zombies.

Han Youlin found a white coat and put it on her. She looked at Guo Lingfeng with infinite tenderness. She only listened to her gentle way: "Mr. Guo, come and draw blood quickly?"

Guo Lingfeng: "

What a beeping dog!

I finally brought your sisters to this laboratory. The atmosphere hasn't breathed well. Are you turning your face and refusing to recognize people?

draw blood? draw blood? Kill me!

Confucius really said the right thing: "it's hard to raise women and villains!"

Han Youqi said with a smile, "don't be afraid, Brother Guo. I'll draw blood for you to eat this later!"

As she spoke, she also shook a sugar in her hand that she didn't know where to find.

My slot! What do you mean? Am I a child? Do you still need candy for an injection?

After drawing 200 ml of blood, Guo Lingfeng felt no feeling. He was afraid except for the needle. After drawing blood, he took the sugar and thought it tasted really good.

The Han sisters all sat at the laboratory table and began to do the experiment. Guo Lingfeng had nothing to do, so she first found a room to lie down and rest.

For him, the physical exertion for one or two hours is not small, but the mental pressure is not small. He was afraid of an accident with the Han sisters all the way, and always kept a high degree of concentration. At the moment, he was really a little tired.

In his sleep, he vaguely saw that he had killed all the zombies in Seoul. Just as he wanted to celebrate, he saw a huge zombie twice as big as T3 suddenly appear.

Guo Lingfeng bombarded continuously with RPG. The huge zombie was unharmed. In a hurry, he quickly took out the Italian gun and hit the target, but the zombie was only blown out of a hole about a foot in his chest, but he was still not dead.

When the zombie rushed forward and punched him in the face, Guo Lingfeng suddenly woke up with a cold sweat on his back.
