Chapter 644: Laboratory Building Basement

The people in this first tunnel should not be very strong.

He continued walking forward, looking at the tightly closed iron gate in front of him. He reached the door in two minutes.

I raised my hand and turned the door handle, and the door opened after a while. The second tunnel was equipped with an induction light.

As the iron gate opened with a sound, the sensor lights in the tunnel lit up. In this second tunnel, the walls on both sides, up and down, were covered with scratches.

In addition to the scratches, there were some dried bloodstains. He raised his hand and touched those scratches. Some of the bloodstains that had already dried up were accompanied by some debris.

It stuck between his fingers. Xiang Yu chased it carefully. Looking at the crumbs on his fingers, Xiang Yu clapped his hands and continued walking forward.

Every time she took a step forward, the sensor light behind her went out. When she turned her head and looked back, she saw a dark corridor behind her.

The light at the end is at the first tunnel.

As if giving her guidance.

In this second tunnel, Lu Er and his companions must have experienced a long battle, because the bloodstains on the surrounding walls were of varying ages.

These scratches should have been left by the irrational madman in the tunnel.

He walked quickly towards the gate of the third tunnel. The moment he opened the gate, Xiang Yu was stunned for a moment. What appeared in front of him was not a tunnel.

Instead, there was a staircase leading underground, and there was a dim light at the corner below the stairs.

After listening carefully, there was no movement inside. Xiang Yu took a step forward with his right foot, stepped down the stairs, and walked down step by step.

And just as her entire body left the second tunnel, the door behind her slammed shut.

Fortunately, her ears were quite sensitive and she had heard the noise just now. If an ordinary person came here, he would be shocked by the situation.

In the dim light of dusk, Xiang Yu was calm and not at all disturbed by the scene before him.

When I walked to the first corner and looked down, I saw another corner below. It seemed that from this floor, there was a direct route to the basement of this laboratory.

After turning three corners in a row, we entered the basement, which had a floor height of at least fifteen meters.

When his feet stepped on the ground, Xiang Yu turned his head to observe the surrounding environment. It was pitch black all around, and he wondered whether Lu Er and others had installed cameras here.

Xiang Yu gave up the idea of ​​taking the flashlight from the space.

In front of me is a small tunnel that is five meters long. The two sides of the tunnel are all stone walls with traces of excavation on them.

After passing through the tunnel, there is an iron gate in front of you, and above the gate is a green safe passage sign.

When Xiang Yu raised his hand to the door handle and was about to open it, he noticed that there seemed to be a picture on the wall next to the iron door.

After a closer look, I realized that this picture was actually a map of the basement, and there were a total of seven floors below.

No wonder Lu Er and the others knew how many floors there were in this basement. This door was difficult to open and required some force.

After Xiang Yu opened it easily, the door closed automatically without any resistance. There was also a magnetic attraction on the inside of the door.

The door was sucked very tightly. Xiang Yu estimated that it would be easy for her to open it, but it would be difficult for an ordinary person to open it.

It takes at least five adults.

Lu Er and others experienced fierce fighting in this tunnel. The smell of blood still smelled fresh, obviously having been left behind recently.

There were many bullet holes on the walls and many bullet heads on the ground. Before they had time to deal with them, Xiang Yu bent down and picked up a bullet head.

He discovered that there were traces of blood on it, and a strange smell drifted into his nose, so Xiang Yu brought the single head closer.

After comparing the location where the bullet fell, Lu Er and others should have fired at the tunnel gate at that time.

And the madman who had lost his mind was standing here at the time. He squatted down and looked at the bullets on the ground. Xiang Yu discovered that these bullets should have been shot into the opponent's body at that time.

Moreover, these bullets are special. But even after these special bullets penetrated his body, he could still live on.

This shows how strong that person's body is.

When they reached the fourth tunnel, before Xiang Yu opened the door, a strong smell of blood entered his nostrils.

The bloody smell rushed straight to my head, and even a pool of blood flowed out from the crack of the door.

This tunnel is the one that Lu Er and others passed through last week. He said that several brothers died in it.

It took some effort to beat the madman inside to death. Xiang Yu became more and more curious about what the two empires were researching.

It's surprising that there are so many crazy people guarding here.
