"I'll try my best...... The personnel of this base were evacuated in an orderly manner, and most of the materials and documents were taken away at that time, and I don't know how many useful things I could find out. ”

Zhang Hong was also very embarrassed by Liu Yuxin's request. More than 100 years have passed, the underground base that lacks normal maintenance has been in a humid and closed environment for a long time, and most of the paper has been moldy and rotten. He had searched the offices as he passed through the first floor, and had not found any valuable clues in them at the time.

Continuing to move along the corridor covered with various warheads and bullet casings, Zhang Hong and the others successively discovered seventeen or eighteen rooms dedicated to the storage of culture tanks, and counted these experimental materials according to 100 people in each room, and the scale of these experiments was staggering.

At the end of the corridor is a large disc-shaped field, with five passages at the edge of the field equidistantly opened, all with etched Chinese marks where they lead; In the middle of the disc field, a lifting platform of more than 200 square meters is tightly embedded in the metal floor, and at each of the four corners of the elevator is a guard robot installed with a base that can rotate 360 degrees. At this time, the automatic guards were all drooping their rectangular heads, and the Vulcan cannons and rocket launchers that had empty ammunition were also hanging limply at the sides of their bodies.

Gong Liang stepped forward to inspect the console, and spread his hands to the others:

"The power supply has been cut off, and there is no way to go down to the fourth floor from here"

"Then let's look elsewhere for a way to the main control room."

Zhang Hong was mentally prepared for not being able to go down from the elevator, he looked around the passages, and whispered:

"The logistics department, the maintenance center, and the experimental center...... Let's go to the experimental center first, shall we? Maybe somewhere to find something!"

Zhang Hong skipped the logistics department and the maintenance center, and directly chose the experimental center. For a secret base for biochemical research, there is no doubt that the most information can be gathered in the experimental center. As for the other comparison observation field, which has been taken care of by various light and heavy weapons, it is obviously the reason for the accident in this base, and I believe that after experiencing the fire, there will be no useful information left.

After a short passage, the rooms on both sides of the metal walls began to multiply, most of them separate rooms with some discarded equipment, and occasionally suites with several small rooms, which were also broken into the door by the xenos.

"Huh?"

Zhang Hong unexpectedly found a good department.

It was a well-protected research suite, with a very thick wall from the outside window, and an alloy closed door to ensure that the things being studied in the room did not have any contact with the outside world, and also kept the house safe from xenomorphs.

Zhang Hong pointed to the closed door:

"Can you open it?"

Liu Yuxin crossed the sterilization room, which had lost its function, and grasped the handle of the closed door with both hands:

"I'll try...... Hey!"

The alloy door slid slightly, revealing a gap.

"It seems that there is no problem. Get out of the way!"

Finding that she had the opportunity to open the door, Liu Yuxin adjusted her center of gravity, pulled the horse step to put herself in a state where it was easier to exert force, and then shouted:

"Open!"

The door to the laboratory was slowly opened, and the first thing that greeted everyone's eyes was an operating table in the center of the table, on which several metal rings held a mutated creature more than 2 meters in place.

The creature bears a resemblance to a human, with a bald head and pointed ears, sharp nails growing from the ends of its fingers, and the soles of its feet several times larger than those of a normal human, with sharp toes like hooks. After more than a hundred years of time, the body has not shown any signs of decay except that it is a little dry and colorless!

Is this what those people in the tank look like when they mutate? Why did Area C study turning humans into aliens at the time?

With a barrage of questions, everyone glanced at the rest of the room.

As the door opened wider and wider, everyone saw more details: this was a place dedicated to the dissection of this creature, in addition to the one on the operating table, there were various organs that had been decomposed soaked in large and small glass jars, and on the other equipment in this room, there were more or less some tissues belonging to this creature.

After the door was completely pushed open, everyone saw a large number of bones and a few rotten work cards with lanyards in a corner of this laboratory, Zhang Hong walked over and picked up one, on which was a middle-aged man with good facial features:

"Nangong Shi?"

After filtering it in his mind, Zhang Hong didn't find his relevant information, Zhang Hong threw the work card in his hand back to the ground and picked up another one:

"Southern Court!"

Zhang Hong's face quickly changed color, and he immediately changed another one, and then the work card slipped off Zhang Hong's finger and fell to the ground.

Professor Sun walked over and silently patted him on the shoulder.

"Professor Sun......"

"Don't say anything, let's go!"

After comforting Zhang Hong, Professor Sun turned to leave.

Everyone immediately followed Professor Sun out of this slaughterhouse-like laboratory, where there were evils that people couldn't look at directly, and people hated this place from the bottom of their hearts.

The undying Zhang Hong led everyone around the third layer, and sure enough, as he expected, he didn't gain anything, except for knowing through those culture tanks that this base was using the human body to do some kind of experiment, and the other information was almost destroyed by the xenomorphs who invaded here later.

Except for the human bones scattered all over the ground and the traces of battle scattered throughout the floor, which showed that there had been an extremely fierce military confrontation here, Zhang Hong had not found any valuable clues in the level, and most importantly, they had not found any other roads to the ground.

"I'm going to die! I'm going to die! ”

Zhang Li, who couldn't see hope, sat on the ground with a mutter, and couldn't care that a skull was looking at her faintly, she had hardly stopped today, and she was really tired now.

"Let's take a break first, and gather the information gathered by the way."

Professor Sun also found a slightly clean place to sit down, and the fatigue of the road made him, a man who has entered old age, feel unbearable.

Zhang Hong also found that except for himself and Liu Yuxin, the physical strength of the others was more or less exhausted, and hurriedly cleaned up a vacant land:

"Everybody, come here! Let's brainstorm and talk about our findings, and maybe we can find a way out. ”

Liu Yuxin was the first to respond to Zhang Hong's call, bounced out of his mecha, and sat next to Zhang Hong:

"I think there must be another passage to this base! I don't know if you have noticed it, the entrance in the subway station is not very spacious, it seems to be just a personnel passage, and large machinery cannot be driven in smoothly at all. So there should be an emergency passage in the fourth floor that leads directly to the outside. ”

Zhang Hong nodded after Liu Yuxin finished speaking:

"Yes, there can't be only one exit from the base. Looking at the structure of this base, the fourth floor of the base is the generator set, weapons and equipment depot and security center, there should be a safe passage guarded by heavy troops, and large equipment and equipment are entered through that entrance. ”

"But don't we have no way to get to the fourth layer?"

Zhang Li was immediately deflated when she heard that the last way to survive was on the fourth floor.

"The fourth floor is an area that is forbidden to ordinary people, except that this lift platform does not have an ordinary access passage, but it does not mean that there is no way to lead to the fourth floor."

"You mean, the ventilation pipes, the sewers?"

Gong Liang instantly understood what Zhang Hong meant, the use of honeycomb structure to divide ventilation pipes and sewers into small spaces that are impermeable to different species in important bases is still a technology that has emerged in recent years, which contains countless bloody lessons. And in the early design of the base, it was simply impossible to take this into account, and they could go down to the fourth floor through these passages.

"That's right!"

Zhang Hong looked at his terminal, then took out an overcoat from his backpack and threw it to Professor Sun

"It's late at night, everyone have a good night's rest, and we'll go down to the fourth floor early tomorrow morning to find a way out!"

——————

Because the scale of the base is relatively large, and its ventilation ducts are surprisingly spacious, the group easily walked through the fourth floor, and the only one who was a little uncomfortable was Liu Yuxin. Finding the first air outlet on the fourth floor, Zhang Hong kicked the cover open and jumped down first.

Now he came to a barracks, with two dozen rusty double-layer iron beds neatly divided into two rows, and on the wall near the barracks gate, six alloy explosion-proof cabinets were lined up.

Zhang Hong stepped forward quickly and tore open the lock of the explosion-proof cabinet, disappointing that the weapons on the gun rack in the cabinet were also rusty. Zhang Hong sighed:

"Looks like this place has also been raided......"

If it weren't for the accident, the soldiers wouldn't have left their weapons here at all.

After several other people got out of the vent one after another, Zhang Hong took the lead out of the door:

"Be careful, everybody! This level is connected to the ground, and it is likely that there will be xenomorphs. ”

Although most xenospecies don't like hard metal and don't nest in places like that, the world is so big that it's hard to guarantee that there aren't such maverick species.

The group on high alert finally arrived at the door of the main control room of this base, this building had very conspicuous traces of fierce battles like the rest of the fourth floor, and Zhang Hong and the others only prayed in their hearts that the equipment inside would not be damaged too badly.

Zhang Hong opened the door of the main control room and walked in lightly.
