Soon, a pattern of strange birds in the fire attracted Lin Feng's attention.

Lin Feng stopped and looked at it, and saw that the strange bird in the turbulent fire looked very much like the shape of a modern fighter. However, under the exaggerated style of prehistoric humans, this "strange bird" has a mouth and eyes, and seems to be roaring.

Lin Feng's stopping also attracted Martha's attention. She leaned against Lin Feng's arm outside, looked at the pattern of the firebird, and said incredible, "It's really funny that the ancients painted the plane like this."

"This is normal. After all, the ancients' cognition is different from ours. Even if they are fighters, they will think that they are living divine birds."

Lin Feng smiled and said.

Then, everyone continued to move towards the depths of the quiet passage.

Not long after walking, everyone entered a ring corridor, which was composed of a stone house. Although nearly ten thousand years have passed, the stone house is still intact and even clean and spotless.

Judging from the situation on site, the order to stop work must have come very suddenly, because the stone houses were all open and the angles of the doors opened were different.

Some stone doors have been carved with carvings and paintings full of imagination by the ancients, while some stone doors are still blank and have not been processed.

Because Lin Feng and Martha were watching the murals along the way, they gradually fell to the end of the team.

After the leader Gasol entered the ring corridor, he stopped and stopped leaving, while Martha learned from the previous lessons and walked obediently behind.

Lin Feng was walking and stopping.

At first, Lin Feng's face was quite calm, but when he walked in and finally came to Gasol's side, his face had become very serious.

Because there was a faint sour smell floating in the air.

It tasted exactly the same as the strange caveman they encountered on the road.

Lin Feng held the gun handle of his arm with his backhand and listened carefully to the movements in the corridor. You must know that at this time, he had already penetrated more than 4,000 meters underground.

The heat emitted from the center of the earth makes the ring corridor slightly stuffy. Fortunately, the air here is abundant and there is no feeling of being stuffy.

Lin Feng calmed down and felt the air in the corridor, felt the gentle breeze, and said simply "two systems."

Gasol immediately understood these stupid words.

He knew that Lin Feng meant that the outside hall and the underground ring corridor air exchange system were completely different, and even the energy supply in the two places was completely different.

After the lobby outside lost its energy, the lobby here still maintained an independent, fully enclosed constant temperature environment.

This is also the reason why the murals in the passage are still in a new state. It is also why Lin Feng and others couldn't smell the sour smell in the air before entering the corridor.

Energy is the key to everything.

If this underground flight laboratory still retains an independent energy supply system, it is likely that it will retain an independent security system and continue to operate.

The energy that Lin Feng carries with him has to be connected to the control room, support the operation of the hall, and open the underground passage.

Now, the strongest weapon carried by Lin Feng and others is Gasol's laser gun, but the most important point is still energy.

Although laser guns are powerful, if they want to become weapons, they must also charge them! What is the difference between laser guns that are not fully charged and fire sticks!?

This is why Gasol brought this thing but never took it out.

The "official box" brought by Lin Feng has been left in the control room above to power the entire system, so Gasol has only a laser gun but cannot charge it.

"Maybe we're a little too anxious."

Lin Feng pondered and said, "We still have many details but haven't figured out, so we hurriedly entered here. Now should we reconsider how to carry out the next action?"

"I agree, you can talk about it first."

Gasol skillfully took out his pistol, pulled the bolt, and said while alerting.

"Because the information we have is not complete, there are several issues that must be clarified first, so let's sort it out one by one."

Lin Feng thought for a while and continued, "First point, where are the people here? Look at the rooms, this place can accommodate at least hundreds of thousands of people.

How did such a huge number of people disappear?”

Gasol held the gun in both hands and thought for a while, "What do you mean? Do you have any ideas or speculations?"

"Hundreds of thousands, or even hundreds of thousands, it may take decades or even longer to train them to become qualified workers.

So I suspect that the workers here are not completely humans, or half of the general human machinery. They may have received only some simple training, but some kind of chip is implanted in their bodies.

Therefore, they have the knowledge beyond that era and are greatly inspired to their imagination and creativity.

But this is not a natural evolutionary ability, so when they disappeared, human knowledge level instantly regressed for thousands of years.

Only under such assumptions can everything in front of you be explained.

If this place was destroyed because humans had spyed on the power of the "god", then under this assumption, there are two possibilities.

First, some wise men in humans awakened and stole chips made by "God" and installed them for their companions. This workflow operates completely according to the program set by "God".

They built a large number of underwear and began to research and make ‘artifacts’, namely the chariots of the gods and the aircraft.

But the "God" discovered all this and modified the program, which led to the prehistoric human beings triggering the "God" trap, such as unplugging the axis of time and activating the security system in the base.

But prehistoric humans did not know the danger of doing this. They still followed the process and came into contact with the light network one by one in a daze, disappearing one by one.

In the end, the "God" launched and attacked, triggering a magnetic storm, destroying the energy system here, and playing a role in destruction. However, the "God" did not expect that after spending five thousand years of evolution, human beings entered the realm of "God".

This is the first possibility.”
