Everyone relaxed physically and mentally, and rested in the room for a while.

Half an hour later, the sound of footsteps from outside the door stopped the noise.

After a while, the door was knocked: "General Bieber, I'm taking you into the fifth district."

Lu Yu walked to the door and looked out through the cat's eyes, and found that it was the lieutenant colonel who had brought them in before.

Without any trace, he returned to the sofa and sat down. Lu Yu dusted his clothes: "Please come in."

Squeak!

The door was pushed open, and the lieutenant colonel walked in with a smile on his face, holding a stack of documents in his hand.

"General Bieber, you and your men will follow me. We will officially enter the fifth zone now!"

Lu Yu nodded and greeted He Chenguang and others to follow.

The group followed the lieutenant colonel into the huge building.

Passing through the long corridor, stopping in front of a thick metal door.

Lu Yu roughly estimated that this metal iron gate is at least about two or three tons.

A password lock is placed on the door.

The lieutenant colonel stepped forward, and immediately shot a laser from the password lock, aiming at the pupil and scanning the side.

Beep!

A mechanized sound was heard, and the metal door slowly opened to both sides.

The wide space behind the door was exposed, and it turned out that this was just an elevator.

Enter the elevator one by one, and the door slowly closes again.

Lu Yu glanced up and found that there were no floor buttons in the elevator.

But the elevator seemed to be able to detect people automatically and slowly descended.

Lu Yu counted silently and roughly dropped to more than a dozen floors underground before he could hold on.

Didi.

The door opened again and a group of mermaids came out one after another.

There was no fluctuation on Lu Yu's face, but he was shocked in his heart.

The lieutenant colonel smiled and turned around, spread his arms to everyone and took a deep breath: "General Bieber, gentlemen, welcome to the fifth district!"

"This is the most confidential and technological place in the world!"

Lu Yu nodded with a smile on his lips: "It's really good!"

But he cursed hard in his heart.

That old guy Hu Guohai is a fucking trick!

The fifth area is actually built underground, why didn’t you say it earlier?

In this way, the difficulty of the task can be increased by several times!

And looking at the underground facilities here, they are more than ten times larger than those on the ground.

Taking a deep breath, Lu Yu could only calm down.

Since you have come, you can still complain no matter how much you complain, think about how to complete the task.

"Let's go!"

Everyone followed the lieutenant colonel and walked towards the fifth area.

Along the way, Lu Yu and the others saw various laboratories, secret institutes, and many rooms that could not be named.

This covers different aspects of weapon research, biological science, genetic science, etc., and almost all cutting-edge scientific and technological fields are involved.

As everyone walked forward, the lieutenant colonel introduced Lu Yu at any time: "General Bieber, you see that the scientific scope of our fifth district is very wide. If you have any needs, you can give us any time..."

As they were talking, the group just turned to a corner, Lu Yu quietly winked behind.

This is a blind spot, no surveillance.

Lu Yu took a step back without hesitation.

Thumb.

He Chenguang and others rushed forward quickly.

Before the lieutenant colonel could finish his words, he knocked him and several staff members unconscious.

There is also a door next to the corner, which is a storage compartment.

"What are these damn ghosts eating every day, so take advantage of it?"

Wang Yanbing complained, and several people worked together to stuff the lieutenant colonel and staff into the storage compartment and destroy the door lock.

Lu Yu walked to a hidden dark place and took out a small computer the size of a palm.

Open it, quickly enter a line of commands, and intrude into the monitoring system to make a little modification.

Froze the screen and then play it in a loop.

In this way, it is equivalent to erasing their figures in the surveillance and never appearing.

After the modification, Lu Yu quietly withdrew, calling He Chenguang and others to come around.

"From now on, everyone starts to act separately!"

Lu Yu shouted in a deep voice: "Remember, we try to control our time within ten minutes, and we must dig out what secrets are hidden here. Don't panic when encountering problems, leave after finishing them, don't stay for too long, do you understand?"

"Yes!" Everyone looked at each other and responded in unison.

"Split!"

Lu Yu spit out a word and everyone scattered.

Then, he also picked up a bend path and rushed out alone.

The places you pass along the way are either all kinds of weapons research institutes or biological research.

Lu Yu walked all the way and didn't find what he was looking for at all.

Um?

Lu Yu, who was racing, suddenly his eyes flashed and he found a huge laboratory in front of him.

The size of this laboratory is more than a few times larger than the ones he had seen before?

"Damn..."

Lu Yu subconsciously swears and slowly walked forward: "Is it an aircraft carrier here?"

The laboratory door was closed tightly, so I had to move to the glass window next to me and look inside.

When he saw this, he was shocked.

Like being struck by lightning!

"This...this..."

Lu Yu murmured to himself for a long time, but couldn't say a word.

Because the things in the experiment were so shocking.

If the outside world knows, it will definitely cause shock to the whole world.

Even a world-class war may be triggered due to the competition for resources!

The huge interior space of the laboratory is as big as half a football field.

Countless scientific researchers in white coats were scattered inside, busy in front of all kinds of top scientific instruments.

This scene made Lu Yu feel as shocked as if he had entered a science fiction movie.

But these are not the key!

I saw countless mysterious objects like wreckage scattered in the center of the open laboratory.

A model similar to a spacecraft is being displayed on the large screen hanging in the center, which seems to be a spacecraft...

Lu Yu's heart was pounding, he carefully hid his good figure and continued to observe.

The spacecraft model displayed on the large screen is completely different from the spacecraft system in the world today.

This is the flying saucer style that only appears in a science fiction movie, which has exceeded human existing cognition.

"Damn it! This is not, it's not really an alien spaceship..."

Lu Yu was shocked and had such a ridiculous idea.

It’s not a big mistake for him to have such a big brain!

It is really the wreckage of the spacecraft in the laboratory, and it is indeed not like the technological product on Earth.

Of course, with human beings now lagging behind, they can't create such a thing at all.
