I racked my brains to think about it, but I didn't have any clue, and I knew that I would have learned the principle of the ventilator in advance...... Now I can only be a dead horse as a live horse doctor,

I took out an electrician's knife and began to cut the black ventilation pipe, and after cutting for a long time, I only broke a small hole, but it had begun to seep out.

Just when I was anxious like ants in a hot pot, I suddenly heard someone inside shouting: "Who moved the sewage valve, and if the drainage valve is closed, something will happen,"

I knew that the place where the sewage valve was discovered, and I immediately ran over with a flashlight, pretending to see what was going on.

I saw someone restore the valve to its original state, it seems that the choice I made before was right, the valve they adjusted must be beneficial to the casino, and vice versa,

"Master, what's going on with this valve, why can't the stagnant water in the ventilation system be clean," I stepped forward and took the initiative to ask, and took out a cigarette and handed it over.

"I don't know who moved the valve, closed the drain valve, and opened the connecting pipe, it's just nonsense,"

"Where is this connecting pipe connected to, and what is the purpose," I asked again, and saw that the water on the ground was receding.

I knew that this valve must be the switch that controls the sewer, and once it is closed, all the water cannot be discharged, but I don't understand the function of this connecting pipe.

"This connecting pipe is connected to the drainage system upstairs, and as soon as the water on the upper floor comes down, fortunately the sewer pipe is not turned off,"

"What would happen if I turned it off," I asked casually, and my heart was already secretly nervous.

"If you turn it off, the sewage will come out of the floor drain, and all the water will not be discharged, and if you turn off the sewer valve, it will be flooded,"

"I see," I nodded thoughtfully, although I don't understand this, but people do.

What's more, this guy is also a logistics staff inside the casino, he must know the situation here very well, and he will also know how to ruin this place,

"By the way, master, will the water on the ground above come in through the ventilation pipe, and what if it is backfilled?"

"It's okay, the upper ventilation pipe won't leak, even the occasional little rain won't get in the way, because the ventilation pipe is very high above the ground and has special protection,"

As soon as these words came out, I immediately thought of the rows of ventilation pipes disguised as sewer pipes, and I knew where the key problem was.

If you want to let the ground water pour into the underground casino, you have to go through the ventilation system, but the ventilation ducts are very high from the ground and will not be flooded.

"Master, but why can't I put the water clean just now, where does the water in the ventilation duct come from?"

"I don't know which ventilation pipe is broken so it will leak, usually the ventilation should not be affected, and a little rain will not affect it, but today there is water on the top so there must be a leak,"

"yes, yes, then I'll go up and check it out," I nodded my head in thanks, thanking this guy for teaching me how to destroy this place,

In the blink of an eye, this guy went back and continued to tinker with the generator, I quietly closed the drain valve, I knew there was only one chance,

When I left the distribution room, I saw that the vents in the corridor were still dripping, and Li Xiaojing said that the vents on the basement floor were also dripping, so there must be a leak in the ventilation pipe.

The ventilation system is directly connected to the above passage on the ground, there will be no valves and no switches, as long as the water enters the ventilation pipe, it will become a vast ocean.

Now what I'm going to do is to completely destroy the leaking pipes and pour all the water on the ground in.

Flashlight came to the vicinity of the elevator entrance, several waiters were standing with flashlights, and when they saw me, they immediately greeted me.

They saw that I was carrying a kit and my respectful appearance disappeared in an instant, it is estimated that they are responsible for waiting here to evacuate the gamblers, and now the entire casino is basically empty.

"Little teacher, the pipe in the bathroom is broken, you can hurry up and take a look," a waiter called me anxiously, and I nodded pretendingly,

When I came to the door of the bathroom that I destroyed just now, the corridor was already full of stagnant water, and the entire bathroom had been filled with water, and the pipe that had just been smashed open was still bubbling out.

The faucet I opened just now has been turned off, and only the broken pipe is constantly bubbling water, and the water is almost up to my shoes.

"Where is the valve of this pipeline, just close the valve," I asked deliberately, and the waiter's face changed.

"This is a sewer, there is no valve at all, and all the dirty water upstairs is flowing down,"

"I see,"

I know that this pipe is a sewer pipe on the ground, and all the sewage stored in it is the sewage that cannot be discharged from the upper floor, and it is flowing violently at the moment.

"Such a big hole, I have to go back and get tools to fill it, and I have to change the pipes,"

"Little teacher, I'm annoying you, you have to hurry up, or you're going to flood here,"

"Okay, take me to the stairs, I'll go up and talk about it,"

The staircase is very narrow, and I don't think anyone thought there would be a power outage here, but it was hard to guarantee that there would be no natural disasters or anything like that, so I reserved such a staircase.

I went up the stairs to the basement level, and I shone a flashlight on the vents where the water was still dripping, and there was a foul smell in the air.

I groped my way to the bathroom on the basement floor, the whole bathroom was smelly, and it was estimated that the toilet that was blocked by me was not opened.

There is a layer of stagnant water on the ground when I enter the bathroom, and I shine a flashlight on it, and there is also a PVC pipe here, which is estimated to be a pipe connecting the drainage on the ground.

I took out the claw hammer and broke the pipe directly, and the muddy water with rotting leaves immediately flowed out, and I shone it with a flashlight and felt that it should be stagnant water on the ground.

Judging by the speed of the flow of water, it will take a few hours or even more than ten hours to fill this place, and it is estimated that it will not take that long for this place to be repaired, so I turned on the faucet in the bathroom......

After leaving the bathroom, I returned to the ground, and at this moment there were a lot of people gathered near the door, some jumping to scold my mother and some were constantly apologizing......

There was a mess at the whole entrance, there was water outside, the car couldn't start and leave, I lowered my head and pulled down the brim of my raincoat to cover my face as much as possible.

I walked quickly through the crowd and saw that it was still raining outside, but the raindrops had become much lighter, and it was already past eleven o'clock in the evening.

I squatted down and touched the stagnant water, the water on the ground was almost twenty centimeters, and it had overflowed the middle of the car's tires, and I thought that the water should be enough to pour into the casino.

On one side is a row of ventilation pipes disguised as greenhouse drainage pipes, all of which are flooded with water.

I don't know which of the pipes is leaking, so the vents on the first and second floors of the basement are leaking slightly, but I'm going to break the bottom of these pipes,

Behind him is a group of people gathered here, if you want to break these ventilation pipes, you have to be in front of all of them, it seems dangerous but you can take it by surprise,

At this point, I decided to take a risk, pretending to be overhauled, no one should find the clues, the water leakage below is a matter below, and it will be too late for them to find out.

I took out a cigarette and lit it, then rolled up my pants and walked into the stagnant water with my toolkit, behind me were dozens of pairs of eyes, and I was going to do this under everyone's gaze,

This time, I bet on people's blind herd mentality, under the gaze of more than a dozen pairs of eyes, they will not think that I will do sabotage, but think that I am doing normal maintenance.

I've gambled countless times, but never once was I doing things in plain sight, I waded through the stagnant water step by step to the side of the ventilation pipe, and there was a crowd more than ten meters behind me.

I squatted down and pretended to inspect it, but I didn't dare to destroy the nearest ventilation pipe, and instead walked forward to check them one by one.

At this moment, I don't have to look back to know that there are dozens of pairs of eyes looking at me behind me, and my groping one by one will create an illusion for them, and it will also create an illusion for them psychologically.

When I found the third ventilation pipe, I took out a screwdriver, stabbed into the PVC pipe in the water, and then pulled hard to expand the broken hole.

I felt that the strength in my hand was not enough, so I simply took out the claw hammer and began to knock on the screwdriver, and knocked the PVC ventilation pipe in a few clicks.

I put away my tools and groped in the water with my hands, and then swung the broken place so hard that I could clearly see the water pouring in.

I stood up and took my tools to the next ventilation pipe, and at this moment my heart was extremely calm, because I knew that the dozens of pairs of eyes behind me couldn't see anything, because there was no crazy person like me in the world,
