"Be careful, someone is coming." Zhao Jianfei patted Lin Rui, and both of them squatted and hid aside.
A secret society militant came over with a gun. It seemed that he was just patrolling and did not find Lin Rui and Zhao Jianfei. So after walking around for a while, he started to turn around and walk back.
"It seems that our guess is correct. There must be their guards in front. This guy is just a mobile sentry." Zhao Jianfei nodded.
"That's right. But have you noticed that although this underground facility makes use of ancient ruins, there are some things that ancient ruins don't have." Lin Rui looked at Zhao Jianfei and said.
"Ventilation duct." Zhao Jianfei looked at the top of the underground facility. There was a large square ventilation duct above their heads.
"That's right. These ancient ruins were originally surface buildings, so of course they didn't need any ventilation facilities. But now they are buried underground. The lack of air circulation is the most fatal weakness 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.
It will also be equipped with a fan room to maintain air circulation in such a large underground facility. This is the basic condition. "Lin Rui smiled.
Zhao Jianfei also smiled, "So, this is where our opportunity lies."
"These ventilation ducts are made of metal and are heavy, so 16mm screws were used" Lin Rui looked up at the ventilation ducts.
"That is to say, as long as we unscrew the screws of the ventilation duct, we can crawl in from the duct." Zhao Jianfei nodded. "Look out for me and give me a few minutes."
Lin Rui nodded, Zhao Jianfei emerged from the dark corner and climbed onto the roof of a truck silently.
Standing on the roof of the truck, he could easily reach the ventilation duct at the top.
Zhao Jianfei tested the firmness of these ventilation ducts with his hands, then hugged them with both hands and lightly turned over and climbed up the ventilation ducts. It moves as lightly as a cat.
Lin Rui was below, helping him keep an eye on the guards patrolling. Although this underground garage is large, there are not many guards patrolling it.
In addition to the patrol they encountered before, there is also a fixed sentry at the exit.
So Lin Rui just had to keep an eye on the patrolling guard and warn Zhao Jianfei directly before he came over.
By this time, Zhao Jianfei had already taken out the tools and slowly turned the screws.
Fortunately, these ventilation ducts are designed to be replaceable. Mechanical connections are made using screws rather than 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 one by one and placed them on the top of the ventilation pipe, trying to avoid making too much noise.
These ventilation pipes are fixed on the top of this underground facility. If one of them becomes detached, it is likely to cause abnormal movement.
Therefore, Zhao Jianfei must be very careful in his actions.
Suddenly, there was a knocking sound in Zhao Jianfei's wireless earphones, and he knew that this was a signal sent to him by Lin Rui.
It means that the patrolman turned his head and walked this way again, although Zhao Jianfei's position was high above his head and it was quite dim.
But this underground garage is quite empty, and as long as there is a little movement, it will be obvious.
You can clearly hear the sound of the guards' boots hitting the ground.
Zhao Jianfei did not dare to take risks and could only suspend the action. But now his situation is actually quite dangerous, because he is lying on a ventilation pipe that has most of the screws removed.
Although these ventilation pipes have a suspension structure at the top, his current weight is completely pressed against the ventilation pipes connected by only one screw.
It is easy to cause the two sections of ventilation pipes with the screws to be removed to become misaligned and make abnormal noises.
So Zhao Jianfei didn't dare to move at all. He could only continue the work at hand until the guard walked around and left.
But the guard walked very slowly, and it took almost a minute to reach their location.
And he actually stopped right here instead of continuing.
This position is indeed quite awkward. Zhao Jianfei is now above his head, lying on a square ventilation pipe.
And Lin Rui was hiding under a car below. The result is that. The Crimson Tide guard stood still against the truck.
This puts Zhao Jianfei in a dilemma. He could only continue to lie downAbove the ??-shaped ventilation duct.
? It won¡¯t work if you continue to tighten the screws, and it won¡¯t even work if you just jump down and hide.
Because of the current situation, any movement may alert the guard below.
¡°However, lying motionless like this is not an option. If the guard raised his head, he might still be able to spot the shadow on the ventilation duct above his head.
So 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 also enough to block his figure.
But just as he was moving, the pipe, which had already had most of its screws removed, suddenly moved slightly.
One of the screws he placed on the pipe actually rolled down.
And the guard is below now. If the screw were to fall, it would probably fall on top of his head or on his body.
Zhao Jianfei knew something was wrong, so he tried his best. He quickly reached over and grabbed the missing screw in his hand.
Just a little bit, the screw was going to jump away. Zhao Jianfei was also frightened into a cold sweat, especially in his current posture, with most of his body exposed. Outside the ventilation duct.
If the guard raised his head, they would probably make eye contact.
Zhao Jianfei also had a screw in his hand, and he was holding on to the ventilation duct with his other hand, with most of his body hanging outside the ventilation duct.
Relying entirely on the strength of your arms and waist to keep half of your body in the air.
At this moment, the guard finally moved. He looked around, then adjusted the weapon hanging on his chest and continued patrolling.
Both Zhao Jianfei and Lin Rui breathed a sigh of relief.
Zhao Jianfei watched the guard walking further and further from above. It was estimated that it was difficult for him to hear his own voice, so he climbed over the ventilation duct with force.
His composure and calmness ultimately saved their lives.
If Zhao Jianfei just lost his composure, he should adjust his posture while the guard is still there. One hundred percent it would make a noise, even if he was very careful not to touch the ventilation ducts.
But the friction of clothing will still make a very obvious sound.
Lin Rui also helped him sweat from below. After the guard left, Lin Rui leaned out and gave Zhao Jianfei a thumbs up.
