Call...

Luo Cheng held the steering wheel with both hands and breathed a long sigh of relief, then looked up at the rearview mirror, only to see that his forehead was covered with fine sweat, he raised his hand to wipe a handful of sweat, and then started the car.

After experiencing this scene just now, Luo Cheng no longer had the courage to continue searching, because he was afraid, and for the first time he really felt what it meant to be afraid.

He rushed back to the experimental base as quickly as possible.

Seeing that Luo Cheng drove back, Gu Aotian walked out of it.

"How? What's the catch? ”

Luo Cheng didn't get out of the car, he was still sitting in the driver's seat, and the car hadn't turned off yet.

Gu Aotian reached in and pulled out the car key, and then put it on the center console.

"Hello? Speak, you do. ”

Luo Cheng: "Do you know what I saw? ”

Gu Aotian glanced at him: "Nonsense, how do I know what you see." ”

"In a place less than 200 kilometers away, I saw zombies! A horde of zombies! ”

Luo Cheng's tone trembled slightly when he spoke.

Gu Aotian: "Cut~ Isn't it just a group of zombies?" I've never seen you scared like this before, huh? ”

Luo Cheng's head shook like dice: "No, you haven't seen that the number of zombies in that group is at least hundreds of thousands!" I wonder where all the zombies that disappeared in this place are gathered, and there is a dense crowd, and I almost scared to pee on the spot! ”

Gu Aotian didn't look like Luo Cheng was joking.

"Are you sure? Are there really so many zombies? ”

"It's true! With so many zombies gathered together, my heart was pounding and my legs were weak. ”

"That's weird, according to you, if there are so many zombies, then why are they gathered together? Although it is not uncommon to say that zombie swarms are in this situation..."

Gu Aotian's heart was full of doubts.

"There's got to be something wrong here, there's got to be something that brings it all together."

"Have you ever looked at them closely?"

"Observe the fart! At that time, my brain was about to crash, so I still had the heart to observe, in case these zombies were alarmed... Huh~~ I feel scared when I think about it. ”

Gu Aotian didn't doubt what Luo Cheng said, but... None of these superficial things seemed to make sense, but he wanted to see them with his own eyes.

The top priority is to assist Robert in developing the antidote, and other things have to be put aside for the time being, and it has taken them more than a month to travel all the way to country M.

Inside the laboratory, Robert and Cheng Huan went in early every day and came out late at night, Gu Aotian and Luo Cheng saw that the two of them were already exhausted.

Another month later... At this time, there are still more than three months left in the countdown to the second half of the year, and Robert has gained a lot in the laboratory during this time, he has thoroughly understood the pathogenic principle of the virus, combined with live experiments on mice, and finally determined that this virus is a biochemical virus that is raging all over the world, and next, it is necessary to develop an antidote.

That night, after everyone finished eating, Gu Aotian kept Cheng Huan and Robert.

"Lao Luo, Huan, you have a good rest tonight, go to bed early, you are too tired during this time."

Gu Aotian looked at Cheng Huan and Robert, both of whom already had obvious dark circles under their eyes, and they were in a poor state of mind and needed to rest.

The development of antidotes is not something that can be achieved overnight, it takes a certain amount of time, and if people collapse, everything is in vain.

And Robert and Cheng Huan are also hard enough, they have been gritting their teeth and persevering in the laboratory for more than a month, and the two of them glanced at each other.

Robert yawned: "It's okay, let's get a good night's sleep tonight, when the antidote is developed, I'll sleep for a week!" ”

Cheng Huan smiled and didn't speak, as the only woman, she actually needed to rest more than anyone else.

This night, Gu Aotian and Luo Cheng took turns to stand guard, Robert and Cheng Huan went to bed early, slept very sweetly, and slept until noon the next day, and after lunch, the two of them continued to devote themselves to the research work in the laboratory.

The days of idleness are extremely painful, especially during this very critical time.

More than two months later, Robert sent out a good news from the laboratory, the antidote has been preliminarily synthesized, but the raw materials in the laboratory are limited, so now they need more raw materials and the receptor of the antidote, that is, live zombies, to verify the effect of the antidote.

Robert told Gu Aotian that there is a biological raw material base that provides high-tech molecular materials to major laboratories across the country more than 100 kilometers away from the Maudekaiser Institute in the northwest, and they need to bring out some of the raw materials designated by Robert to develop a large dose of antidote! In the meantime, you need to catch some live zombies!

There is no problem with this raw material, but this capture of live zombies is very tricky, at present, except for the large number of group zombies that Luo Cheng saw before, there is no single zombie in this place, even if it is a small-scale group of zombies, he and Luo Cheng can't go to the territory of hundreds of thousands of zombies to "catch people", that is simply to send people to death.

After the two of them discussed together, they set off together to get the raw materials, and the experimental base was relatively safe.

The two drove back a large number of raw materials according to the address and information provided by Robert, and on the way they also hoped to meet some lonely zombies, but they were disappointed, and the place they passed was like an empty city, perhaps, those zombies really gathered in that riverbed.

On the way back, the two of them discussed a lot of countermeasures.

"Fatty, looks like we're going to have to take a risk in that place."

"Go... It's okay to go again, but the question is how many zombies are going to be kidnapped from those zombies? ”

What Luo Cheng said was also a question that Gu Aotian pondered and meditated on.

"It's useless to talk so much now, let's put down the raw materials and get ready to go to the site to have a look."

Three hours later, two people drove to that riverbed.

The car was parked a hundred meters away in case the zombies heard the movement and spotted them.

Gu Aotian and Luo Cheng found a relatively hidden place to hide, and then used binoculars to observe the zombie group on the riverbed.

Although he had made sufficient psychological preparations before watching it, seeing so many dense zombies from the telescope, Gu Aotian couldn't help but shiver, only to feel goosebumps fall to the ground.

Zombies of this scale, even in the Resident Evil game, Gu Aotian has never seen it.

After observing for a long time, they finally came to the conclusion that it was impossible to start with these zombies, because they were too densely packed, and it would be good if there were some scattered ones, but this group of zombies was really like a "slowly flowing river", it was like sticking together.
