"This door is so heavy, I can't open it, I may have to find the key."

"The key, except for my father, is on Uncle Lee."

"Where is he?"

"Right in that office, didn't you say there's a zombie in there?"

"Probably it's him." After listening to Dongfang Ao's words, Xiao Yi nodded, and then everyone turned around and came to the door of Uncle Li's office.

"Xue Xin, you float the zombies inside first."

As Lu Xuexin opened the door with her mind. The next moment, Xiao Yi had already turned into lightning and rushed in.

Xiao Yi condensed a lightning ball in his hand and threw it directly.

The zombie entered a trembling state, the axe fell, and the zombie's head had been split, and the red and white flowed all over the ground.

The brain nucleus has been taken into Xiao Yi's hands at this moment. All this was done in a split second.

"Another blue brain nucleus, Xuexin will give it to you."

"I'm going to eat it right now." Xiao Yi nodded.

The next moment, Lu Xuexin directly stuffed into the end, and after closing her eyes for 5 seconds, Lu Xuexin opened her eyes.

"I don't think I feel anything."

"That's it for the ability, if you want to find out what's changing, you need to use it more often, and experiment a lot." As Xiao Yi finished speaking, Xiao Yi's gaze turned to Dongfang Ao again.

"Dongfang Ao, where is the key?"

"Do you see if he has it around his neck?"

"Is this it? Xiao Yi looked at the pendant in his hand with some confusion. ”

"That's it, I saw it last time."

Xiao Yi looked at the key in his hand with some confusion, a little speechless, this is completely a cylinder, a bit like the material of jade.

The only strange thing is that there is a snail on one side, and Xiao Yi doesn't know what it does, but Dongfang Ao has already said that it is the key. So what else.

The next moment everyone set off again for the passage.

Come to the hidden door.

"How do I use this key?"

"I saw my father and they used this key, just insert the snail directly into it."

Xiao Yi took a look, the keyhole that didn't have a keyhole at all.

"Are you sure this thing can be plugged in?"

"That's what my father did.

As the key was inserted, there was a white light, and the next moment the key disappeared.

The moment the key disappeared, the hidden door was reflected, and the door suddenly moved backwards.

In a short time, a tunnel was created that everyone could pass through.

"This is what you call the elevator?" Xiao Yi was a little speechless.

It's actually a huge space, with a track laid downward, and on the track, there are elevator-like things, parked there.

"Which elevator are we going to?" Lu Xuexin asked suspiciously.

"Take your pick."

The next moment, Xiao Yi chose an elevator and walked up.

As the four of them walked up the elevator, Xiao Yi looked at the control panel around him.

"It seems that it can be connected to an identity watch."

The next moment it shows that the connection is successful, and the destination that the elevator can reach is projected on the watch.

"Underground Research Institute No. 1, Underground Research Institute No. 2, Underground Research Institute No. 3, Underground Research Institute No. 4."

Xiao Yi was a little puzzled.

"Dongfang Ao, do you know that Murong Qingqing's parents are in that research institute?"

"I guess it's number one."

After Xiao Yi confirmed, he immediately pressed the button to go to the No. 1 Underground Research Institute.

With the sound of the buzzing motor starting, Xiao Yi found that his body had become heavier, and Xiao Yi didn't know if this was an illusion. The elevator is sliding down at an incredible rate. It's so fast, it's like a free fall.

"What's going on?" All four were a little nervous.

And everyone's eyes are on Dongfang Ao.

"Don't look at me, I don't know."

What Xiao Yi and the others don't know is that at this moment, this underground traffic track has lost its energy maintenance, and it was able to start the elevator before, with all the backup batteries, but after starting, there is no track power supply, resulting in the failure of the brake system.

In other words, the car can only accelerate, not slow down.

"What are we going to do?" If this elevator doesn't slow down, we will definitely fall to our deaths, or crash to death. Dongfang Ao was also anxious at the moment.

Xiao Yi looked at the navigation map on his watch.

At this moment, the elevator that everyone was riding was rapidly approaching the No. 1 Underground Research Institute.

"What's that?" At this moment, Lu Xuexin seemed to have discovered something.

Xiao Yi also looked in the direction pointed by Lu Xuexin through the glass window of the elevator.

"It's ants, how can there be so many ants here."

"That's the ecological testing ground of Biological Research Institute No. 2."

"Then how can there be so many ants?"

"I don't know. I've never seen so many of them before. ”

Xiao Yi suddenly thought that this should be under the playground.

Those ants, where did they run out? Xiao Yi was a little puzzled, did these ants eat something in the research institute and mutate? Or did the apocalypse cause the mutation?

At this moment, the elevator was still moving rapidly, and Xiao Yi saw that he was almost at the No. 1 Research Institute.

Immediately said: "Okay." It's almost time to Lab 1, and you're all holding hands together.

Hearing Xiao Yi's words, Lu Xuexin Murong Qingqing immediately held his hands together, Xiao Yi grabbed Lu Xuexin's hand, and grabbed Dongfang Ao, who was still stunned on the side, and the next moment Xiao Yi performed elementalization.

Suddenly, the four of them turned into a flash of lightning and disappeared in place, and when they reappeared, they had already reached the top of the orbit.

The inertia that should have been borne by the four people did not appear, and in this way, the four of them appeared safely on the platform of the No. 1 Research Institute.

"Is this an ability? It's amazing. At this moment, Dongfang Ao looked at Xiao Yi with bright eyes.

Xiao Yi suddenly had a shuddering feeling, and looked at Dongfang Ao suspiciously.

"That's not right!"

"Xiao Yi, look at the direction we are coming from. What is that? ”

As Xiao Yi's gaze turned, Xiao Yi suddenly noticed that groups of ants were crawling towards this side quickly.

Xiao Yi suddenly shouted: "Run!" Then the crowd began to run quickly.

Research Institute No. 1 was blocked by an iron door, and Xiao Yi didn't have time to try whether he could open the iron door, so he directly asked everyone to pull their hands up, and suddenly Xiao Yi used the elementalization again, and passed through the iron gate in an instant.

There is no light inside the iron gate, it is very dark, and you can't see your fingers.

"Xue Xin, you're okay!"

"I'm fine."

The next moment, electric sparks appeared in Xiao Yi's hands from time to time, and as the electric sparks fluctuated faster and faster, he finally found a balance value, and the sudden electric light stabilized, illuminating everything around him.

It's a passage, and weirdly there's a lot of blood around it.

"What the hell is going on here?"

"Someone should have turned into a zombie, but why didn't I see a zombie?"
