The two men looked at the rotating exhaust fan, which was one person tall enough for people to climb through, and the two men worked together to remove the barbed wire fence above.

The fan is still spinning, and you can't get in until you stop it.

Ryuuji found a spear here, and stabbed it directly at the center of the fan, the fan blades and the spear were combined into one, Ryuuji grabbed the spear and stopped the fan for half a second.

In just half a second, Bai Yilong immediately used his shield to card out the corner of the fan blade.

Two people, apparently only one can go down.

Bai Yilong and Ryuuji looked at each other, and Ryuji spoke: "I'll go!" ”

Bai Yilong twisted his head: "My plan, don't you forget what you should do?" ”

As I said before, Ryuuji is only responsible for recording.

Helplessly, Ryuuji stepped forward and pressed the shield, and could see that the fan began to smoke, apparently the fan was overheated due to the lack of wind to inhale and the motor was starting again.

Bai Yilong immediately rushed into the pipe with a cat pounce, and Ryuuji removed his shield.

I thought in my heart that when the time came, something would happen, as long as I found that Yilong would drill down by himself.

Bai Yilong felt the sound of the wind behind him, and followed the strong wind all the way down, which was a straight downward path. While pumping the wind into the training room, it also sweeps the wind into the ground.

Bai Yilong's feet were propped up on the passage, and there was a fan frantically sucking in inwards below.

I should have thought that there were two of them, and Bai Yilong was in a dilemma at this time.

Vertical pipes, constantly falling.

Helpless, Bai Yilong could only take out the gunpowder in his pocket, this thing is very expensive. Each special operator has only one shot a year. Montenegro was short of all supplies, and only a small amount of gunpowder existed from the only mine.

Wood can only be used for training, and it is not allowed to be used in non-combat environments.

Gunpowder cannot be taken away, but it is easy to be stolen by guards when stored in an arsenal. Therefore, the soldiers generally stored it close to their bodies, used to kill themselves or kill the enemy.

But in the current situation, if you don't use it, you're dead.

Helplessly, Bai Yilong broke the cover, then rubbed it on the back of his shoe, and then threw it down.

The gunpowder fell, then smashed on the blades, and the powder and blades exploded, and the entire blades fell.

Yawen Library

The gunpowder rushed upward, and the heat swept through Bai Yilong's body.

Reluctantly let go of his hand, and the whole person fell down.

As soon as it fell to the ground, someone quickly followed the sound of the explosion.

This is a tunnel that extends in all directions, and I have no choice but to move backwards.

There was smoke coming from his body, and he hid in the corner and covered his mouth, letting his breath down as much as possible.

Bai Yilong was squatting in the corner at this time, and there was a door behind him.

There is a corner here, which just hides Bai Yilong.

Sure enough, there is a basement, and it is very large.

"Why did it explode?"

"The fresh air system is broken!"

"It stinks, it smells burnt."

"This one is broken, I guess it's overheating, call someone to repair it."

"Smell it carefully, it seems to smell of gunpowder!"

"Burnt smell, huh? Where is gunpowder? Ask again when the repair comes! ”

After ten minutes of waiting, the repairman arrived.

"Look what's going on? There is no smell of gunpowder. ”

The repairman looked around, then stared at the damaged fan and said, "It's not the motor that was damaged, it's the fire that damaged it." See the shards? Not a fan. ”

"This?" Thought the guard reached out.

From a piece of fan debris, the repairman found the fragments embedded in the fan blades that did not belong to the exhaust system. The shard, the remains of a powder tube, was immediately picked up by the guards.

"I think it's time to report it, someone might have broken in." The repairman said as he began to replace the exhaust system.

The two of them discussed it, and then went to report it together.

This was a period of meritorious service, so the repairman was left to start repairing the fresh air system with tools.

At this time, Bai Yilong knew one thing, and it was not appropriate for him to run anywhere. But as long as you can change into the clothes of a repairman, you can go anywhere.

Bai Yilong began to sneak behind the repairman, aimed a knife at his neck, covered the other party's mouth and nose and pulled it back, making him lie down on top of him.

Bai Yilong began to drag the repairman and pulled him into the pipe.

There is a ninety-degree fold that places the repairman in the fold. Then he took off the other party's clothes and changed them with himself.

and tied the repairman's mouth, hands and feet with his own clothes, so that he could not speak.

After that, climb down the pipe again, install the fresh air fan, and tighten the screws.

I don't know when this repairman will wake up, and even if he does, he will be trapped in the pipe.

When the other party is found out is a matter of later story, after all, he has been exposed.

Now it's this time to rely on this repairman's clothes, hurry up and see what's going on here.

Packing up his tools, Bai Yilong walked in the underground corridor with his head down.

This is the basement of the White City.

Who would have thought that a large area had been dug up below, and that there would be electricity for it 24 hours a day.

What to study here? There seems to be a more exaggerated technology.

Bai Yilong walked around the corner and saw a group of soldiers training.

It's the same elite, but the content of the other party's training is completely different.

The weapon in his hand also shoots bows and arrows, but the speed of firing and the number of bows and arrows are something that Bai Yilong can't understand at all.

Looking at the faces of every training soldier, there were no dragons and dragons seven.

I can only go to the next room, the next room is a laboratory across the glass, a group of people are tied up here, and there is something like a black mushroom on their bodies, and their facial features are distorted as if they are screaming in pain, but they can't hear each other's voices through the glass.

Fortunately, I didn't find the dragon seven and the dragon, and at this time I heard the sound of footsteps.

Bai Yilong could only keep his head down and pretend to pass by, and a soldier guard around the corner smiled at Bai Yilong with a weapon: "The exhaust has been repaired, right?" ”

Listening to the other party's voice, he knew that it was the guard just now, Bai Yilong immediately nodded and did not speak.

"The lights in the front C1 area are broken, please go for a while. I'm going to inform the trained soldiers and search the whole area to see if I can find the intruder. After speaking, the guard smiled and walked to the training camp a few meters away, pressed open the gate with his palm to enter it, and called out to the soldiers who were training inside to come out, indicating that there was a new mission to be distributed.

The other party only recognized the clothes, and did not find Bai Yilong at the first time.

Bai Yilong leaned over and walked slowly, looking down to see the soldiers passing by him. Looking at their new weapons, to be honest, I was a little envious.

The area here seems to be the same as the above, so the road of C1, Bai Yilong will understand how to go if he makes up for it.

Immediately calm down and walk towards the C1 area.

There is also a downward passage in the corridor, and the rope around the waist of the clothes is hung on a hook to go up and down.

That is, this place is far larger than Bai Yilong imagined, similar to an underground secret base that is not open to the public.

There are about 1,000 people in the research and development of science and technology and scientific research here, which is the real core secret of Baicheng! So even if it was a real black mountain, it would be attacked by the Flying Fire Dragon, and the city lord was not afraid to find the reason.
