"Owner, don't go over yet, wait for us to go over to check the safety. Pen, fun, pavilion www. biquge。 info" Liu Yi said when he stopped Liu Haoyu, who was about to go inside.

Anyone who looks at it knows that what they have to face now will be a very dangerous situation, Liu Haoyu is the backbone of everyone, if he encounters an accident here, everyone will not think about anything at all.

"It's okay, the air here has been circulated, and no toxins have been detected. There may be some dangers, but I don't think you would have been more dangerous if I couldn't handle them. Liu Haoyu shook his head.

He had been here for more than an hour, and as long as there was no virus here, he felt safe. Even if there are monsters in the movie here, I am not afraid. Liu Yi was worried about his safety, and correspondingly, he was even more worried about their safety.

After clearing a gap in the pile of bones, everyone continued to walk inside. Bones can be found everywhere in the passages and in the room, and the contents of the room are all scattered on the floor.

"Damn, I don't think there's been a Resident Evil here." Liu Haoyu said depressedly.

With the underground building and the white bones on the ground, as well as the marks of gnawing, he felt that this place was like the Resident Evil he had seen at the beginning, with zombies infested.

At that time, the umbrella company also set up research institutions underground, and they were also business giants, who knows if the forces behind this hope star are also the same as the umbrella company.

He felt that this force had a lot of similarities with the umbrella company, economically, militarily, and technologically, it had this strength.

The more he thought about it, the more he felt as if he had guessed it well, and he became more and more nervous. He's really worried about zombies popping up, this thing is not easy to kill. I have all been resurrected in this era, and it seems that it is not impossible to have a few zombies.

Everyone didn't think much about the "Resident Evil" that Liu Haoyu just talked about, but felt that Liu Haoyu said it very appropriately. There must be something going on here, most likely being infected by a biochemical virus, and then the deranged catches and bites.

There are not many floors of underground buildings here, only two floors, but the area is very large. After careful searching, no trace of the creature's presence was found.

"Owner, there is still a passage over there, but there are too many caves extending out there, and I have arranged for someone to defend over there." Liu Yi came to Liu Haoyu and said.

"Allocate some more vehicles to come over, and if there is danger, it is estimated that they will come from that side." Liu Haoyu nodded.

There was always a sense of danger in his mind, and although it was empty now, the feeling of danger was getting stronger and stronger.

A team of people followed Peng Boyuan here to collect information and see if they could find something useful from the data left behind.

Liu Yi was not idle, although the passage found at the end was not easy to explore for the time being, but it could be roughly observed from above the ground.

"Owner, the place where the passage extends should have been a volcanic crater before, and I don't know when the eruption opened the place connected to the sea, and then the sea water poured in. Now there is a bay diagonally above our heads, and there are many species of marine life because of the volcanic eruptions. After a careful review, Liu Yi came over with the latest data and reported.

"I don't know if they discovered this volcano first, and then opened this passage underground to build it." Liu Haoyu glanced at the display map and said.

Nature is also a very magical existence, and there are many underground passages in the extinct volcano, and there is a natural concealment in building an underground base here.

However, this extinct volcano can also erupt suddenly, and when it erupts, it will destroy all the passages that connect it to the outside world. Judging from the results scanned by the detection robots released by Xiao San, the large and small caves underground are connected to each other, and there are also some rocks after the solidification of volcanic lava.

"But don't relax, I always feel dangerous. There must be areas that our robots haven't explored, and those waterholes don't know where to lead. Liu Haoyu continued.

Or for that reason, this place has always given him the feeling of danger. It stands to reason that now that the investigation is almost complete, there should be no hidden monsters, but his heart has not relaxed.

"Owner, if you don't go back first, I'll just keep an eye on it here." Liu Yi spoke again to persuade.

"It's okay, let's figure it out here, otherwise I'm really not at ease." Liu Haoyu shook his head.

"Owner, owner, we may have found something terrible." At this time, Peng Boyuan's eyebrows flew and he ran over and said.

"How?" Liu Haoyu looked at Peng Boyuan and asked.

"These people are actually here to study how to extend the life span of humans, and judging by some of their records, they have made some breakthroughs." Peng Boyuan said.

I can only say that the people here are really crazy and really dare to think. Those transformed warriors are actually the by-products of their research, and the main research here is to see if they can make humans immortal.

In the interstellar age, many species have been discovered, and many of these species have a lifespan of more than a few hundred years.

Immortality has always been a dream of human beings, and it is a wish that all powerful people look forward to fulfilling, and these people here are to study how to live forever.

Judging from some data, some of the natural life forms they cultivated can theoretically live to about 200 years old.

This is not a joke, because there have long been studies that have shown that the lifespan of human beings is limited at birth, even if you are free of disease, your brain cells are also dying, and eventually the whole body dies.

The direction of research by these people here is how to delay the rate of death of human brain cells and how to improve the physical fitness of the human body. They have done experiments on some small animals and have verified their theories.

Don't look at the average life expectancy of human beings now with the support of advanced medical technology, it has exceeded 120 years, but who doesn't want to live longer?

"Don't be too happy just yet, it's obvious that something is wrong with their research, otherwise there wouldn't be such a result now. No matter what era it is, it's balanced, and if you want to get extra returns, you have to pay a certain amount. Liu Haoyu frowned and said.

"Uh, yes. It seems that there is something wrong with the sanity of these subjects, but there is no detailed description, and they also had an accident shortly after the human test was conducted. Peng Boyuan said with some embarrassment.

Just now, he was also attracted by experiments that could extend human lifespan, and he wanted to carry out this experiment according to the current experimental results and some data, and even he naturally ignored the potential dangers brought by this experiment.

"Did you hear anything?" Liu Haoyu frowned and asked.

Liu Yi listened carefully and shook his head.

Liu Haoyu closed his eyes and carefully searched for the strange noise he had just heard. After listening for a while, his brows furrowed, could it be his own delusion? But just when he wanted to give up, he heard the not-so-heavy sound again, as if someone had accidentally touched something while crawling.

"Liu Yi, have you checked these air-conditioning channels?" Li Haoyu looked at Liu Yi and asked.

"I've checked it, but the air-conditioning tunnel here is too large, and if there is anything hidden inside, I'm afraid it will be difficult to find it." Liu Yi frowned and said.

Since Liu Haoyu asked so, he must have suspected that there was something in the air-conditioning passage. However, the area here is too large, and the air-conditioning passages are also criss-crossed, so it is not so easy to check.

Hearing the conversation between the two, the guards who brought them naturally aimed their guns at the air conditioning outlet in this room.

The creatures in the passage were also cautious, as if they smelled danger, and did not continue on.

"Captain, there seems to be a creature in the waterhole." After a stalemate for a while, Liu Yi's intercom system came with a report from a team member.

As soon as Liu Yi touched his hand to the walkie-talkie, the baffle of the air conditioner outlet was knocked open, and a gray shadow jumped out of it, targeting one of the guards.

The gray shadow was agile, and even if these people fired together, they still didn't hit it with the help of aiming.

The people who can be brought over by Liu Yi are the best in the defense force, and their main task this time is to protect Liu Haoyu's safety, and they don't know what kind of danger they will encounter, so they naturally have to bring the best. But even then, instead of knocking the Grey creature down, it allowed it to trick the defender into the side.

"Ah" A scream came from the mouth of the guard, and when everyone saw it clearly, they were not scared into a cold sweat.

The gray creature was biting the team member's throat with its mouth open, but its mouth couldn't close because Liu Haoyu's hand was inserted into its head entirely. If Liu Haoyu is even half a minute at night, this team member will die.

The danger of this team member was lifted, but there were many screams in Liu Yi's intercom system.

"The squads are on emergency alert, looking for cover, and waiting for our rescue." Liu Haoyu said directly.

Judging by the speed at which the creature had just attacked, it was far from what these defenders could handle. They move too fast, and they are very fierce.

Even with the reminder, the screams continued to sound. In just a few moments, 34 people have lost their vital characteristics.

"Little San, cut off the power supply to the outside and drop the gate." Liu Haoyu commanded Xiao San.

Although there are no super viruses here, there are very dangerous unknown creatures here. If they are released, I am afraid that it will be even more harmful than the virus. (To be continued.) )
