'Sea King' Ye Xi was sandwiched by Xie Ning and Pei Hongqing and walked forward, unconscious.

The eye is always looking around.

The passage is three meters wide.

Except for the gray ground under the soles of the feet, the sides and the head. The tops are all made of metal.

There are also vents at intervals of a few meters.

Bursts of aroma emanated from the ventilation ducts.

It's weird.

She frowned, felt that something was wrong, and said to Pei Hongqing: "Can you blow these aromas to the side?" ”

Pei Hongqing snorted.

The wind ability he unleashed rushed to the vent, blowing the scent back.

The smell of the aroma in the passage faded, and gradually, a familiar stench came from the front.

It's the smell of decomposing zombie corpses......

It just took a few turns.

Xie Ning slowly stopped and looked at her: "There are still twenty meters left, and there are several third-level mutant zombies." ”

"Let's go straight to it."

Ye Xi ran over quickly.

Twenty meters is really not a long distance, and soon I saw a glass door, and there were several third-level mutant zombies in white coats standing at the elevator door.

As soon as the three pairs of black and red eyes saw Ye Xi, they became extremely excited.

Ye Xi took the seed out of his bag and threw it at the gap under the glass door.

The seed rolls to the feet of the Level 3 mutant zombie.

The glass door was smashed by them before it was smashed.

Bang!

The thick vines had already wrapped all three of them around their bodies, and they collapsed to the ground.

When Ye Xi walked over, he didn't even need a knife.

Directly pluck off three heads with vines.

Remove the crystal nucleus.

After walking such a long way, I came to the three elevators of the underground laboratory of this Kaizhong Group.

Of course, these elevators are out of service.

Breaking open one of the elevator doors and looking down the elevator shaft, she found that the floor of the underground laboratory was deeper than she had imagined!

Shainin stood next to her and said in a deep voice, "The underground laboratory should have at least five floors, and this is the only entrance at the moment. If we want to go in, we have to go straight down from this position. ”

The main thing is that there is no safe passage here.

Access is by elevator.

Then how did those fourth- and fifth-level mutant zombies stay inside?

From other entrances?

I can't think of this for the time being.

And after coming over from the passage, when I walked here, I could only see the three third-level mutant zombies and the three elevators.

"Aren't there any vents?"

Pei Hongqing looked at it again. top of the ceiling, "you can see which direction it leads." ”

"You mean, wait for the soldiers to split up and enter this underground laboratory from two directions?"

Ye Xi looked at him.

Pei Hongqing nodded, "This underground laboratory has a total of five floors, and it is absolutely impossible to have only one passage. Otherwise, if something happens, it will be the result of everyone dying inside. I have also checked the information of Kaizhong Group, and their group has attracted a lot of scientific researchers. These researchers are so important to a pharmaceutical company that it's impossible not to take their safety seriously. ”

Xie Ning glanced at him, "Then why didn't you find out that Kaizhong Group has bought high insurance for all scientific researchers?" ”

Pei Hongqing paused, "This can only show that Kaizhong Group is indeed researching some very high-risk things, but it is not surprising that many pharmaceutical companies will also buy high insurance for researchers, and the beneficiaries cannot be companies." ”

Ye Xi heard the conversation between the two.

A more in-depth question comes to mind.

couldn't help but look at Pei Hongqing and Xie Ning, and asked them, "Do you know how the zombie virus appeared?" ”

“……”

This question.

Pei Hongqing was stunned, "I don't know, someone suddenly got hit, turned into a zombie, and began to bite other people." ”

Shainin was silent, "The reason is unknown, and the army side is not clear." ”

This is not perfunctory, it is.

Even if in the previous life, the antidote appeared, I don't know how the virus appeared.

His biggest suspicion is this Kaizhong group.

But if it really comes out of the Kaizhong Group, it will only be S City that will fall at the beginning, not a global outbreak.

It can only be said that it may be inseparable from Kaizhong Group.

"It's weird."

Ye Xi touched his chin, also puzzled.

Because in her memories of her previous life, there is no memory of the origin of the zombie virus.

Even if the superbase is built.

The army, the government, did not say where the zombie virus came from.

In the end, what she knew was nothing more than Lu Ye's research on the antidote to the zombie virus.

But knowing how to study the antidote doesn't mean knowing who made the zombie virus.

In short, the source of the zombie virus has been a mystery to her for two lifetimes.

However, Pei Hongqing said that the decision to divide into two teams to go to the underground laboratory was feasible for her.

Because in addition to going down to find the fourth-level spiritual mutant zombie, she also had to find equipment.

Moving the equipment away is the biggest goal of this visit!

"Let's go back first."

Ye Xi said to the two: "Let's plan how to carry out the next actions." ”

Xie Ning and Pei Hongqing had no objections, and walked back after her.

However.

Just after they turned to leave.

The buttons of the three elevators are all lit up!

-

The other side.

Yan Fei and the others also consumed a lot of abilities before they directly broke through from the periphery into this inner perimeter.

A group of ten people, tired and out of breath.

I finally found a place to catch my breath.

There were three or four more mutant zombies rushing towards them.

Although they are all fourth-level abilities, there is no problem in killing these mutant zombies, but they can't stand the large number!

Fortunately, with their captain Yan Fei, in a flash, in less than a breath, the heads of the third- and fourth-level mutant zombies who came over were cut off.

One of them also rolled down in front of Yan Ziming's feet.

Dead eyes stared at him.

was already tired to death, but now he couldn't hold back and kicked that head out.

"Oops! Boy, the crystal nucleus hasn't been dug yet! ”

Liang Lin shouted and went to pick up his head again.

Yan Ziming touched his nose embarrassedly and apologized: "I'm sorry, I didn't expect it, I felt a little annoyed......"

"What's so bothering with the crystal nucleus? This thing in the last days is money! ”

Liang Lin looked at him amusedly, "But your kid behaved well just now, and the captain said that the crystal nucleus of this fourth-level zombie will upgrade you." ”

After speaking, he stuffed the dug crystal nucleus into his hand.

Yan Ziming was immediately flattered, "How embarrassing is this, I didn't do anything." ”

looked at Yan Fei again, "Captain Yan......"

Yan Fei was smoking, swallowing the clouds and spitting fog, looking at the location of the Kaizhong Group Building, and when he heard his words, he said, "Upgrade, don't hold back." ”

“……”

Yan Ziming couldn't cry or laugh, so he could only accept it.

Liang Lin looked at Yan Fei, "Captain, this mutant zombie's attack on us has weakened, could it be that Zhou Hui and the others were discovered and turned back inside?" ”
