As we entered June, the rain was getting heavier and heavier, and the wind was blowing outside, and the windows and doors of the storage room were beaten.

No wonder the kitten didn't come.

Cats hate water and are probably more sensitive to the weather than humans, so it is now estimated that the cat is sheltering from the rain.

These days, Chen Du has become accustomed to having a cat accompany him when he is working, the difference is only that he is inside, and the cat is outside, the cat scratches the door from time to time and meows twice, and Chen Du will knock on the door if he is interested, although the sound is small, but it is estimated that with the cat's acuity, he can hear a little.

Thereupon.

Occasionally, a person and a cat communicate in this way.

The rain that I have been waiting for for several days has finally arrived, and God is very generous, this time the rain is very abundant.

After only a minute or two, the outdoor storm sewer was already draining.

And their newly built aqueduct also clearly emitted the movement of water flow.

"And it worked!"

The sound of the water flowing in the pipe made everyone feel high, after all, before this, even Tang Jing was not 100% sure that this big guy could run perfectly.

But now only a small part of it is running.

The other end of this pipe leads directly to the outside, but there is an additional opening in the middle of the pipe.

For this water outlet, Chen Du was embarrassed for a long time at that time.

Apparently.

A screw-on cap that resembles a mineral water bottle cap is still difficult for him now.

This has always been a headache for Chen Du.

He's now able to do a lot of incredible things with his abilities, and even Iron Man's armor is getting more proficient, and he can even manipulate a piece of plastic into a human form and make it dance, but he can't do anything about a bottle cap.

The reason is simple.

This kind of thing requires precision, not imagination.

It doesn't even have much to do with mental power.

This is not difficult to understand.

Humans can paint the Mona Lisa's beautiful paintings, but without the help of tools, the average person can't even draw two parallel lines.

And precisely.

But it is one of the cornerstones of industrial civilization.

Chen Du has always been using some qualitative things to replace quantitative ones as much as possible, such as this water connection, he originally planned to create a flip cover and buckle pattern to replace the threaded opening.

Although the airtightness will be poor, it is still sufficient, after all, even if there is a small amount of leakage, it will soon flow out through the crack of the door.

But on second thought.

The so-called promotion of strengths and avoiding weaknesses is actually not a compliment here.

If you want to revive human civilization, his ability is obviously a shortcut, but if you can't even make things like threaded gears, then the so-called revival of industry is a joke at all.

Therefore, Chen Du immediately decided to try no matter how difficult it was.

He has seen a lot of inspirational stories of getting up early in China to overcome technical difficulties, and now it is barely appropriate to put it on himself.

So, even though the work had been overloaded in those days, and the body and mind were very tired, Chen Du still insisted on making a threaded cap.

The process is actually quite boring.

It's nothing more than trying over and over again.

Every day, he would make threads when he had the most energy, and when he was tired, he would switch to other simple tasks until the whole diversion project was finished.

The screw cap is finally made.

This is a 1 cm diameter, white plastic threaded cap, because of the lack of rubber ring as a sealing material, the inside of the lid part, and a groove is carefully made.

This may be the first real industrial product since the end of mankind, and it immediately attracted everyone's attention.

Everyone went up and stroked a few times.

And Tang Jing was full of praise, but then there were some difficult words, such as "check valve" and "Y-shaped filter", which caused everyone to open their mouths.

……

It rained heavily for about a minute.

He Ying said, "I'll go open the water outlet." ”

The location of the water outlet is more than ten centimeters high, although Chen Duan made a ladder, but this kind of climbing, He Ying usually volunteers.

"Wait." Tang Jing said.

"Why? What if the rain stops in a while? ”

"Look at the way this rain looks, it won't stop for a while and a half, and the initial rain can't be used, at least after ten minutes."

"What's the point of that?"

"Because it's dirty, let the rain wash the roof first, and after a while, the water will be relatively clean."

"And that said?"

"Initial rainwater is a very important concept, some enterprises such as iron and steel chemical industry, the first ten minutes of rainwater is to be collected and treated, can not be discharged indiscriminately." Tang Jing explained.

"Okay."

In fact, people don't understand it very much, but they are also used to not digging deeper.

Listening to the sound of rain that was even more majestic than the last time, ten minutes passed quickly.

"Okay, it's OK." Tang Jing pinched the time and said.

"I'll go." He Ying nodded.

"I'm also together, the lid is too big, and there is the impact of water, and it is estimated that it is difficult for one person to operate."

After Chen Du finished speaking, he climbed up with He Ying.

In order to facilitate the operation, Chen Du made a platform at the place where the water connection is located, which can be enough for three or five people to stand.

The two of them stood on each side, holding the round lid with both hands.

"Turn!"

One lap, two laps......

As the lid was unscrewed, the water was rushing out.

"Be careful, get out of the way."

When the lid was completely removed, the two of them couldn't hold it at all, so they could only let it be washed away by the current, splashing and wetting both of them.

"Damn, forget about that."

Chen Du watched the huge plastic lid being washed to the ground, feeling a little helpless.

However, the flow of water from the water inlet was accurately shot into the sedimentation tank, which made everyone breathe a sigh of relief.

The two hurriedly came down, and together with everyone, retreated a distance, and watched the water diversion project run.

The water begins to flow slowly into the sedimentation tank, the water level slowly rises, and when the water level reaches its highest level, the water follows the overflow and enters the reservoir.

A few more minutes passed.

The water tank is also slowly filled, and the excess water is drained to the outside through the overflow into the drain.

Because it was the first time to use it, all the containers needed to be rinsed several times, Chen Duan opened the drain pipe at the bottom of the water tank, and soon, the drainage speed was faster than the incoming water, and the water level dropped again.

After a few times, close the drain.

"That's it." Tang Jing clapped her hands.

Everyone looked at the water tank that was filled in front of them, which seemed to be three stories high, and they couldn't tell with joy.

The days of not being able to take a shower may soon be gone.
