"I'll try my best... The staff of this base retreated in an orderly manner. Most of the information and documents were taken away at that time. I don't know how many useful things can be found."

Zhang Hong was also very embarrassed about Liu Yuxin's request. Over the past hundred years, the underground base lacking normal maintenance has been in a humid and closed environment for a long time, and most of the paper has been moldy and rotten. It is undoubtedly a dream to obtain some information on the daily operation of the base from it and then analyze the information of the base! When he passed the first floor, he carefully searched the various offices, and did not find any valuable clues in it at that time.

Continuing to move forward along the corridor covered with various bullets and shells, Zhang Hong and his team discovered seventeen or eighteen rooms that specially placed cultivation tanks. They counted these experimental materials according to 100 people in each room, and the combined scale was astonishing.

At the end of the corridor is a huge disc-shaped site. Five channels are equidistantly located at the edge of the site. The etched Chinese on the above channels indicates where they will lead. In the middle of the disc site, a lifting platform of more than 200 square meters is embedded in the metal floor. Each of the four corners of the elevator has a guard robot equipped with a 360-degree rotating base. At this time, the automatic guards all drooped their rectangular heads, and the Vulcan cannons and rocket launchers that fired ammunition were hung weakly on both sides of the body.

Gong Liang walked up to check the console and spread his hands at the others:

"The power supply has been cut off, and I can't go down from here to the fourth floor"

"Then look for the way to the main control room in other places."

Zhang Hong was mentally prepared for not being able to go down from the elevator. He looked around the passages and muttered in a low voice:

"Logistics Department, maintenance center, and experimental center... Let's go to the experimental center first? Maybe where can I 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, the experimental center can undoubtedly collect the most information. As for the comparison observation site that has been taken care of by various light and heavy weapons, it is obviously the reason for the accident of this base. I believe that after experiencing the catastrophe, there will be no useful information left behind.

After walking through a not-so-short passage, there were more rooms on both sides of the metal wall. Most of them were separate rooms with some used instruments inside, and occasionally there were suites made of several small rooms inside. They also broke into the door and ruined the things inside.

“Huh?”

Zhang Hong accidentally discovered a complete department.

This is a scientific research suite with good protection. From the windows outside, it has a very thick isolation wall. An alloy sealed door ensures that the things studied in the room will not have any connection with the outside world, and also protects the house from invasion by aliens.

Zhang Hong pointed to the closed door:

"Can you open it?"

Liu Yuxin walked past the disinfection room that had lost its function and held the handle of the sealed door tightly with both hands:

"I'll try...hee!"

The alloy door slid for a moment, revealing a gap.

"It seems that there is no problem. You can get out of the way!"

Found that he had the opportunity to open the door, Liu Yuxin adjusted her center of gravity, pulled her horse stance and made her feel more likely to exert force, and then shouted loudly:

"open!"

The door of the laboratory was slowly opened. The first thing that caught everyone's eye was an operating table placed in the center seat. Several metal rings on the table fixed a mutant creature more than 2 meters.

This creature has a somewhat similar appearance to that of humans. It has bald head and sharp ears, sharp nails growing at the ends of its fingers, and its soles are several times larger than ordinary humans, and its toes are as sharp as hooks. After more than a hundred years of time, the body has not shown any signs of rotting except that it is a little dry and has no color!

Is this what those people in the culture tank look like after mutating? Why did Area C study turning humans into aliens at that time?

With a series of questions, everyone glanced at other parts of the room.

As the door opened, everyone saw more details: this is a place that specializes in dissection and researching this kind of organs. In addition to the one on the operating table, various organs that have been decomposed are soaked in glass jars of large and small sizes. On other equipment in this room, there are more or less tissues belonging to this kind of organism.

After the door was completely pushed open, everyone saw a large number of corpses and several work cards with broken lanyards in a corner of the laboratory. Zhang Hong walked over and picked up one. It was a middle-aged man with a well-known facial features:

"Nangong Shi?"

After filtering it in his mind, Zhang Hong did not find any relevant information. Zhang Hong threw the work permit in his hand back to the ground and picked up another one:

"Nan Gong Court!"

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

Professor Sun came over and patted his shoulder silently.

"Professor Sun..."

"Stop saying anything, go!"

After comforting Zhang Hong, Professor Sun turned around and left.

Everyone immediately followed Professor Sun out of this slaughterhouse-like laboratory, which was filled with evil that people could not look directly at, making people dislike this place from the bottom of their hearts.

Zhang Hong, who was unwilling to give up, led everyone around the third floor, and as expected, he did not gain anything. Except for the cultivation tanks, he learned that the base was using the human body to perform some kind of experiment, the other information was almost destroyed by the aliens who later invaded here.

In addition to the human bones scattered all over the ground and the battle traces spread throughout the floor, it shows that there has been an extremely fierce military confrontation here, Zhang Hong has not found any valuable clues on the floor. The worst thing is that they have not found other roads to the ground.

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

Zhang Li, who couldn't see hope, muttered and sat on the ground, and couldn't care about a skull looking at her quietly. She almost didn't stop today, and she was so tired now.

"Everyone take a break and gather the collected information."

Professor Sun also found a slightly clean place to sit down. The fatigue along the way made him, a person who had entered the old age, feel overwhelmed.

Zhang Hong also found that except for himself and Liu Yuxin, the others were more or less exhausted, so he quickly cleaned up an open space:

"Everyone comes here! Let's brainstorm and talk about our discoveries. Maybe we can find a way out."

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

"I think there must be another passage in this base! I don't know if you have noticed that the entrance to the subway station is not very spacious and seems to be just a personnel passage. Large machinery cannot be driven in smoothly. How can a large project like a construction base not use machinery? So there should be an emergency passage directly to the outside on the fourth floor."

Zhang Hong nodded after Liu Yuxin finished speaking:

"Yes, the base cannot have only one exit. Looking at the structural diagram of this base, the fourth floor of the base is the generator set, the weapon and equipment library and the security center. There should be a safety passage guarded by heavy troops. Large-scale equipment and equipment come in from that entrance."

"But we can't get to the fourth floor?"

When Zhang Li heard that the last path of life was on the fourth floor, she was immediately relieved.

"As an area prohibited by ordinary people, the fourth floor does not have ordinary access except for this lifting platform, but it does not mean that there is no way to lead to the fourth floor."

"You mean, ventilation ducts, sewers?"

Gong Liang instantly understood what Zhang Hong meant. It was also a technology that emerged in recent years that was emerging in important bases using honeycomb structures to divide ventilation ducts and sewers into small spaces that were impossible to penetrate in different species. It included countless bloody lessons. The early base design could not take this into consideration. They could go down to the fourth floor through these channels.

"That's right!"

Zhang Hong looked at his terminal and took out a coat from his backpack and threw it to Professor Sun.

"It's already late at night, everyone have a good night's rest. We will go down to the fourth floor tomorrow morning to find a way out!"

—————

Because the base is relatively large and its ventilation ducts are surprisingly spacious, the group easily walked to the fourth floor. The only thing that was a little uncomfortable was Liu Yuxin. She found the air outlet on the first fourth floor, Zhang Hong kicked the cover open and jumped down the first.

Now he was in a military camp. More than twenty rusty double-layer iron beds were neatly divided into two rows. On the wall near the gate of the barracks, six still shiny alloy explosion-proof cabinets were arranged.

Zhang Hong quickly stepped forward and pulled the lock of the explosion-proof cabinet. What was disappointing was that the weapons on the gun rack in the cabinet were also rusted. Zhang Hong sighed:

"It seems that there have been a surprise attack here, too..."

If something hadn't happened, the soldiers wouldn't have left their weapons here at all.

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

"Everyone be careful! This layer connects to the ground, and there are likely to be alien species."

Although most alien species do not like hard metals and do not build nests in such places, it is difficult to guarantee that there will be no such unique species in the world.

The highly alert group finally arrived at the door of the main control room of the base. The building, like other places on the fourth floor, had very conspicuous signs of fierce fighting. Zhang Hong and others only prayed in their hearts that the equipment inside would not be damaged too seriously.
Chapter completed!
