The moment the elevator opened, a large number of zombies gathered at the elevator entrance frantically poured into the elevator, but fortunately, Li Yunfei made sufficient preparations in advance and blocked most of the zombies with his body.

And the two rows of soldiers standing behind him reacted very quickly, raising the 81 bar in their hands at the first time to strafe and kill all the zombies gathered at the elevator entrance.

Li Yunfei shook off the sticky dirty blood on his body vigorously, turned his head and didn't forget to give Chen Fei a thumbs up and praised:

"Brother Chen, your hunch is so accurate! Fortunately, I prepared in advance, otherwise we would have been wiped out by these zombies in such a narrow space. ”

Chen Fei just smiled back and didn't continue on the topic.

The soldiers who came down to carry out the task this time were the squad with the strongest combat effectiveness and comprehensive quality in the entire company, and after they dealt with the zombies at the door, they quickly rushed out of the elevator and filled the magazines on both sides of the elevator to alert the surrounding situation.

Not long after, dozens of zombies rushed over from other locations on the basement floor, and Chen Fei took Wang Yuanyuan's hand and never came out of the elevator.

Just after they went down to the basement floor, Chen Fei found that there were suddenly two more mutant zombies displayed by the zombie radar, and these two zombies were only within a hundred meters of Chen Fei.

This represents two mutant zombies, not attracted by the noise of the generator on the ground, but mutated zombies themselves in the lower area, but for some reason, they are not detected by the zombie radar when they are on the ground.

The basement floor is a large space, except for the criss-crossing passages, which are individual rooms, and the doors of these rooms are numbered differently, exactly the same as the number on the head of the single bed in the room, giving the impression that this is a hospital room.

The hallway was a mess with dried blood everywhere, and the doors to those rooms were mostly open, and in each of the closed rooms there was almost a zombie dressed in orange, and the chest of the clothes was numbered exactly like the bed on the door.

It doesn't feel like a hospital room, but more like a prisoner being held here!

"Captain Li, come here!"

At this time, the soldier squad leader, who had already walked far away, waved and shouted at Li Yunfei and them, and Li Yunfei, Chen Fei and others hurriedly ran over there. Finally reached the door of a large room around the corner.

In the middle of the room were ten large transparent containers, soaked in dark green liquid, zombies bound in chains.

"Brother Chen, why does this place feel so weird! What the hell is this company researching? ”

Wang Yuanyuan asked Chen Fei in a low voice on the side, she really couldn't stand the strange atmosphere in the room.

Chen Fei looked at the other things in the room and guessed:

"The people at Ultron Biopharmaceuticals, after the day of the full-scale outbreak of the zombie virus, should have let all the people who were not infected go into the underground area, and they wanted to develop a vaccine that could resist the zombie virus, or make some serum that could inhibit the zombie virus.

The corridor we walked just now, if you look closely, you will find that the blood on the walls on both sides is not a time period, and the closest thing is probably just the past few days, and there may be some survivors here now!

If I'm not mistaken, the first floor used to be a place to study and observe all kinds of patients, and as a biopharmaceutical company, if it didn't have one or two specific drugs that could make a name for itself, there would be no way to gain a foothold in the highly competitive market, and the people who were observed here may be just ordinary colds, and some may be AIDS or cancer patients."

At first, Chen Fei pulled Wang Yuanyuan to speak, which made the members of the evolutionary team around him very disdainful, but they just felt that Chen Fei was a pickled girl regardless of the occasion, if it weren't for the relationship between the captain Li Yunfei and Chen Fei, they would have spoken ill of each other a long time ago.

But when they listened to half of it, even if they were disdainful in their hearts, they had to admit that Chen Fei seemed to be really a little clever, and the head of the analysis was the Tao, and what he said was indeed a little meaningful.

"Captain Li, do you think there is any equipment we need here?"

The soldier squad leader, who was not smiling, walked up to Li Yunfei's side and asked, Li Yunfei shook his head and replied: Literature is big

"Some of the instruments that are all tested here are not the laboratory equipment we need, and it is estimated that these things are also behind this floor, so let's go directly to the next layer to save time!"

Although Li Yunfei said this, in order to prevent omissions, Chen Fei and the others quickly took a cursory look at the rooms in the depths, and only after doing this did they return to the elevator and go down to the second basement floor.

Compared with the basement floor, the basement floor is more like a hospital ward, and the layout is basically not much different from the basement floor, but the overall space is smaller than the basement floor.

Several large rooms are also the same as the basement floor, full of zombies and the corpses of patients, one of the rooms is even dismembered by a zombie, the zombie is only a head, soaked in an unknown liquid, the mouth is still closed, very weird.

There was a faint trace of worry on Chen Fei's face, if he encountered a mutant zombie on a wide floor like the first or second floor, it would be relatively easy to solve, but if he encountered it on a floor that was gradually getting smaller below, it would be very dangerous if he could not give full play to his advantage in speed.

Chen Fei's keen perception ability allowed him to clearly sense that the third floor underground seemed to be full of cold air, and that feeling was especially obvious after the elevator descended to the third floor.

The moment the elevator door opened, a cold chill hit the face.

Hiss..... It's cold!

At the elevator door, Li Yunfei gasped, and his body subconsciously shuddered.

Boom.... Boom..... Phew

A few zombies closest to the door walked stiffly towards the elevator, and the soldiers just used the military thorns installed at the front end of the 81 bar to easily get these zombies, most of these zombies were wearing white overalls, and on the left side of the chest was a work card representing identity. On the right side of the dress is the embroidery that represents the company, Altron Biotech.

After everyone walked slowly along the passage for three minutes, Chen Fei and the others arrived at the room where the culprit caused all this on the third basement floor.

It's like a huge cold store, and it's like a morgue.

On the periphery are three rows of metal cabinets filled with small squares, and one of the corpses in a special bag is pulled out at random.

In the innermost part of this room, there are freezers in the shape of capsules that are more than one person high, and through the glass above, you can see the corpses covered in frost.

Chen Fei wiped off the layer of frost on the freezer, and saw a sign that recorded the basic information of the people inside.

The five main pieces of information are name, gender, age, cause, and freezing time.

Seeing this, Chen Fei thought of a piece of news he had heard a few years ago, when it was said that some people abroad used flash freezing to freeze some terminally ill and incurable patients.

Wait until a hundred years after the science and technology are developed enough and the medical level is advanced enough, and the method of rapid thawing and resuscitation can theoretically revive this person, and then use future scientific and medical technology to cure these terminally ill patients.

Of course, all this is just a theory that can be realized, and no one knows whether these terminally ill patients will freeze to death and whether they will wake up in the future.

But it has to be said that this business has given many terminally ill people an extra glimmer of hope, and they can also witness how far human society will develop in the future, and even be able to see their children and grandchildren who are separated by several generations, which can be said to kill two birds with one stone.

Of course, these businesses require high management costs, which do not include the cost of treatment after the recovery can really be revived in the future, which is basically the privilege of the rich.

It is often said that time is money and life, and in the near future, money will indeed be able to buy more time and life!

The reason why the temperature on the basement three floors is so low is that four of the capsule freezers have malfunctioned, not only cooling the inside but emitting cold air relative to the outside space, and the temperature of the refrigeration seems to have reached the limit of the minimum of the equipment.

The third basement floor is a relatively confined space, so now the entire floor is like an ice cave.
