"Be careful, someone is coming." Zhao Jianfei patted Lin Rui, and both of them crouched and hid away.

A secret agency militant came over with a gun. It seemed that he was just patrolling and did not find Lin Rui and Zhao Jianfei. So after turning around for a while, he began to turn around and walk back again.

"It seems that we guessed right, there must be their guards in front. This guy is just a mobile whistle." Zhao Jianfei nodded.

"Yes. But have you discovered that although this underground facility uses ancient ruins, there are some things that ancient ruins don't have." Lin Rui looked at Zhao Jianfei.

"Ventilation ducts." Zhao Jianfei looked at the top of this underground facility. There were large square ventilation ducts just above their heads.

"Yes. These ancient relics used to be surface buildings, of course, do not need any ventilation facilities. But now because they are buried underground. There is no air circulation, which is one of the most fatal weaknesses of underground facilities.

That's why they installed large ventilation ducts, and these ventilation ducts will definitely lead to various locations in this underground facility.

And it will be equipped with a fan room to maintain such a large underground facility and air circulation. This is the basic condition. "Lin Rui smiled.

Zhao Jianfei also smiled, "So, this is our opportunity."

"These ventilation ducts are metal and heavy, so 16mm screws are used..." Lin Rui looked up at the ventilation ducts.

"That is to say, as long as we unscrew the screw of the ventilation duct, we can climb in from the duct." Zhao Jianfei nodded. "Help me take the wind and give me a few minutes."

Lin Rui nodded, and Zhao Jianfei emerged from the dark corner and climbed onto the roof of a truck silently.

Standing on the roof of the truck, he can easily reach the top ventilation duct.

Zhao Jianfei tested the firmness of these ventilation ducts with his hands, and then hugged them with both hands, and the whole person gently turned over and climbed up the ventilation ducts. It moves lightly like a cat.

Lin Rui was below, helping him pay attention to the guard patrol. Although this underground garage is very large, there are not many guards on patrol.

In addition to the patrolman they encountered before, there is also a fixed post at the exit.

So Lin Rui only had to stare at the guard patrolling and directly warn Zhao Jianfei before he walked over.

At this time, Zhao Jianfei had already taken out the tools and slowly turned the screws.

Fortunately, these ventilation ducts are designed to be replaceable. The mechanical connection is made with screws instead of electric welding.

In this case, as long as they can unscrew the screw, they can find a way to get in.

Zhao Jianfei carefully unscrewed the screws and placed them on the top of the ventilation pipe to avoid making too much noise.

These ventilation pipes are all fixed on the top of this underground facility, if one of them is disconnected, it is likely to produce abnormal movement.

Therefore, Zhao Jianfei's actions must be very careful.

Suddenly, there was a knocking sound from Zhao Jianfei's wireless headset. He knew that this was the signal Lin Rui had sent him.

It means that the patrolman turned his head and walked here again, although Zhao Jianfei's position was high above his head, and it was quite dim.

But this underground garage is quite empty, as long as there is a little movement, it will be obvious.

The sound of the guard's leather boots stepping on the ground can be heard clearly.

Zhao Jianfei didn't dare to take risks, so he could only pause the action. But now his situation is actually quite dangerous, because he is lying on a ventilation pipe with most of the screws removed.

Although these vent pipes have a suspension structure on the top, his current weight is completely pressed on the vent pipe connected by only one screw.

It is easy to cause the dislocation of the two vent pipes with the screws removed, causing abnormal noises.

Therefore, Zhao Jianfei didn't dare to move. He could only continue his work after waiting for the guard to leave after a full circle.

But the guard walked quite slowly, and it took almost a minute to get to where they were.

And actually stopped here and didn't continue to go.

This position is indeed quite embarrassing. Zhao Jianfei is now on top of his head, lying on a square ventilation pipe.

And Lin Rui was hiding under the car below. The result is that. The guards of the Red Tide Troops stopped leaning on the truck.

This made Zhao Jianfei a little dilemma. He could only continue to lie on the square ventilation duct.

It won’t work if you continue to screw the screws, it’s even worse if you jump down and hide.

Because of the current situation, any action may alarm the guard below.

However, just lying motionless is not a solution. If the guard raised his head, he might still find the shadow on the ventilation duct above his head.

Therefore, Zhao Jianfei could only move slowly, trying to hide himself completely above the ventilation duct.

Fortunately, the width of this square ventilation duct. It was enough to block his figure.

But when he moved, the pipe that had already removed most of the screws at all, suddenly moved slightly.

Of the screws he put on the pipe, one of them rolled down.

And the guard is now below. If this screw is going to fall, it is estimated that it will fall on top of his head or on his body.

Zhao Jianfei knew that it was not good, so he tried it out, and quickly explored his body, and copied the falling screw in his hand.

Only a little bit, the screw was about to fall off. Zhao Jianfei was also frightened into a cold sweat, especially when he was in this position, most of his body was leaning forward. Outside the ventilation duct.

If the guard looks up, it is estimated that both of them can meet each other.

Zhao Jianfei also pinched a screw in his hand, climbing the ventilation duct with the other hand, and most of his body hung outside the ventilation duct.

Relying solely on the strength of his arms and waist, he kept half of his body suspended.

At this moment, the guard finally moved. He looked around, then adjusted the weapon hanging on his chest and continued to patrol.

Both Zhao Jianfei and Lin Rui breathed a sigh of relief.

Zhao Jianfei watched the guard go farther and farther. It was estimated that he could hardly hear his own voice, and only then did he forcefully flip to the top of the ventilation duct.

His composure and calmness eventually saved their lives.

If Zhao Jianfei just couldn't calm down, he would adjust his posture while the guard was still there. One hundred percent will make a movement, even if he is very careful not to touch the ventilation duct.

However, the friction of clothing still makes a fairly obvious sound.

Lin Rui also helped him squeeze a sweat from below. After the guard left, Lin Rui leaned out and gave Zhao Jianfei a thumbs up.
