call!

Seeing each other's looks clearly, both of them breathed a sigh of relief.

"Kerla, what's the situation on your side?"

"Nothing was found."

The person who came was really Kerla, and when she heard that she squeezed into the dark, she whispered: "I went to the navy colonel’s room to search. There are quite a few things about the branch on the island, but nothing about this laboratory. of."

This result is not unexpected.

Sabo nodded, then said.

"The door is no longer available, we must find other ways to get in."

"Did you find any other entrances on the way?"

Kerla frowned upon hearing this.

"No!"

"That's really troublesome"

Suddenly, Sabo's eyes lit up with a headache, "Wait, if Earl Black's men have searched the laboratory, do you think they will let go of the third underground floor?"

Kerla's eyes lit up.

"Certainly not!"

"Moreover, the exterior wall of this building is made of steel. Even Deyur can't conceal a passage from the outside world."

Digging through soil and digging through steel are two different things!

"Yes!"

Sabo nodded and began to patrol around: "So their people must have been here, and there is an entrance to the underground!"

"This location must be secret enough so that it cannot be discovered by the navy during excavation, and it is safe enough after leaving, so there is no need to worry about being found suspicious by the navy."

After speaking, the two turned their eyes to the machinery that was wrapped in huge oilcloth behind Sabo.

The empty space in the warehouse can be directly ruled out, and the greatest possibility is undoubtedly hidden in these stacked machinery.

With oilcloth as a cover, as long as the navy is not boring enough to disassemble and inspect one by one, the passage is 100% safe!

The two stopped talking, they divided into two groups, and began to search one by one.

After meeting other companions in the middle, and being even more sure that there is no second entrance, everyone looked for them.

soon.

In front of a square nearly ten meters high, Sabo pressed it with his hand. The tarp was pressed down and stretched about 20 centimeters, but it still didn't touch it to the end.

His eyes lit up and he fumbled around the edge of the square.

Sure enough, in the inner corner, above the rope that tightened the tarp, an inconspicuous hole appeared. Sabo gave it a try, and it just happened to fit a person through it.

"This is a cage?"

With the help of the dim yellow light on the ceiling outside, Sabo got in and found that the space inside was not so big.

The thing covered by the tarp is a cage-like thing, not a sea tower and stone prison. That thing has no research value at all. The cage is made of steel. Sabo speculated that Begapunk wanted to make something that could It is a work that replaces Hailou's stone cage to hold capable people in prisons.

Unfortunately, it was not completed.

The entrance and exit of the cage were wide open, and through the holes that were not welded, one could see that the iron fence was hollow and filled with dense metal wires.

In the center of the cage, a pile of gravel and soil was piled beside a hole about half a meter in diameter. The unique smell of old, rotten and moldy in the basement came from below, faintly accompanied by the sound of the wind.

"found it?"

Kerla, who was searching in the distance, raised his head, quickly communicated with his companions with his eyes, and hurried towards Sabo's location.

Soon, a group of people came here.

Looking at the dark hole on the ground, Kerla shuddered.

"Give me the flashlight, I'll let it down first!"

Sabo took off his coat and went into battle, wrapping the rope around his waist.

The others hesitated for a moment without saying much.

It is undoubtedly dangerous to go down first.

The ghost knew if there were any undead squatting down below, and once there was a disturbance, they would have enough space to hide and escape, but Sabo did not.

But no way.

If there is any danger that Sabo can't deal with, it's no use for them to go.

Kerla pulled the rope in her hand and nodded towards Sabo.

Sabo smiled at this, did not say much, bit the flashlight, and gently jumped into the cave.

Humph!

Confirming that it won't affect the above, Sabo turned on the flashlight, and was stunned by everything in front of him.

A chill instantly enveloped him, leaving his scalp numb and cold sweat on his face.

There is no danger, it's just creepy.

Click!

When he reached the bottom, Sabo looked at the glass jar in front of him. After a while, he gathered up his energy and began to check the surroundings, then shook the rope.

This is a signal of safety.

Leaving one person to continue to let the wind go, Kerla and another companion jumped down one by one, and then, like Sabo, their pupils tightened.

"what is this?!"

Kerla covered her mouth, feeling a little at a loss.

Sabo was stunned, and replied with a bit of emotion.

"Probably, it is a failure!"
