Song Ziyu was guided by his men to the location of the sluice gate. He saw that the water level in the upstream of the sluice gate had dropped due to the previous release of water, which revealed part of the water outlet.

I saw that the river below the sluice was covered with reinforced concrete, and in an inconspicuous position of the concrete river, there was a passage similar to the opening of a ventilation duct.

This is……

When Song Ziyu saw this pipe mouth, he was stunned for three minutes!

If I guessed correctly, this should be a water pipe.

A water pipe with a diameter of about one meter!

Such a big water pipe actually goes underground. Where does it go?

Song Ziyu was stunned for a few minutes before he thought of calling Su Zhen to ask.

"We don't know what the mouth of this pipe is used for. Anyway, this mysterious pipe was there when I was a child." Su Zhen racked her brains and finally left her words without beginning or end.

Song Ziyu asked Su Zhen to call in the oldest old man in the settlement for questioning.

When he learned that the water pipe was older than the old man, Song Ziyu suddenly thought of a question, so he asked: "Are there any supporting facilities near this water pipe?"

The old man is sixty or seventy years old and his eyesight is dim. In this world where the average age is less than forty, the old man is indeed an old man, but his mind is very clear and his speech is clear.

After thinking for a long time, the old man finally reacted and said: "I remember seeing some iron pipes and iron lumps when I was playing here when I was a child, but those things were melted by adults to make iron tools."

As he spoke, the old man suddenly remembered something: "No, I remember that there is still a residual iron lump in the settlement."

"Take me to see it!" Song Ziyi became nervous.

Under the leadership of the old man, Song Ziyu walked around and back to the Shoujiang settlement. After rummaging around, he saw the so-called iron lump in a huge fertilizer factory.

The thing was either square or round, and it was rusty and full of various smash marks, but Song Ziyu still recognized what it was at a glance.

Damn it!

This is simply a motor with an output power!

Song Ziyu has seen this kind of motor before, there is one in the shelter!

It still exists in the form of a crew!

The appearance of this kind of thing proves that water pipes must deliver water to a certain place, and must be matched with machinery such as water pumps.

It's a pity that over time, those things were destroyed by the uneducated survivors.

So, here comes the problem!

Where does this water pipeline go?

Song Ziyu returned to the river again, looking at the water pipeline and thinking.

According to the direction of the pipeline, it goes east...

East?

What's to the east?

Isn’t Longshan just to the east?

Song Ziyu suddenly blinked with inspiration and thought of a possibility.

Song Ziyu called Tang Jian, called two motorcycles and returned to Longshan in a hurry.

Returning to the settlement, Song Ziyu plunged into the shelter base.

Arriving at the central management area of ​​the shelter, Song Ziyu awakened the artificial intelligence Han Meimei and retrieved the map of the shelter.

A complex three-dimensional image map appeared before our eyes, with laminated layers inside and outside each other, and various circuit diagrams making a mess.

Song Ziyu felt dizzy and felt like his Tianling Cap was about to burst.

Sure enough, engineers are the weirdest species in the universe!

Song Ziyu couldn't understand the drawings, but it didn't mean that he had nothing to do.

"Han Meimei, find the underground water pipe for me." Song Ziyu ordered.

If you can't do it yourself, why don't you go to the Artificial Intelligence Headquarters?

Immediately, a section of the pipe was cut out and placed in the void.

"The system shows that the power supply at the water pipe port is damaged and cannot be used normally. The water inflow is only 3%." Artificial intelligence Han Meimei analyzed.

"Where does the water pipe lead to?" Song Ziyu asked.

Han Meimei called up another map and marked the pipelines and ports on the map.

Song Ziyu understood it immediately when he saw it.

This water pipe clearly leads to Shoujiang River.

The truth is revealed!

Song Ziyu became excited.

With this water pipe here, what are you afraid of?

Song Ziyu immediately asked Gao Zhongping to put down all other things in his hands, and then mobilized technical personnel to repair the motor and matching water pump.

For those parts that could not be repaired, Song Ziyu went to the civilized world to purchase and customize them, and replaced all those that could be replaced.

Finally, after a lot of effort, the water pump generator set at the water pipe port worked successfully again after many years!

Along with the roaring sound, a large amount of sewage was pumped out by the water pipes, making the entire negative five floors smell bad.

"It hasn't been used for too long, and this water pipe is silted up," Mr. Chen said.

After three hours of sewage discharge, the water released from the water pipes became clearer.

Seeing the water dredged from Shoujiang River, everyone in the settlement cheered.

Water is life.

Unexpectedly, the sages who built the shelter had already thought of a solution to the water source problem that plagued the development of settlements.

"I should have known that such a permanent shelter must be equipped with a water source that can be used for a long time." Gao Zhongping said after thinking.

"That's not all!" Professor Chen inspected a device on the fifth floor and said, "They even prepared two sets of water purification devices, and a spare set."

"These builders are really full of wisdom!" Gao Zhongping couldn't help but sigh.

Song Ziyu was also very emotional.

How could such a wise human being embark on the road of destruction?

…

The problem of water supply unexpectedly turned around.

Although the work of the port pump is still limited by power, it is better than nothing.

Song Ziyu thought about it and decided to use the idle population of Shoujiang to open a canal!

Beating the mother-in-law on a rainy day is just idle time anyway, so these people might as well do something else.

The work of organizing the canal opening was left to Su Zhen. He would provide the technology and Shoujiang would provide the people. As long as anyone was willing to work, he would take care of the food.

As soon as they heard about being in charge of food, the survivors in the Shoujiang settlement showed their enthusiasm and joined in the labor one after another.

Song Ziyu asked Qi Dachun and dozens of brothers to edit and compile a list of workers, and they would get paid for each day they worked.

So on the first day of construction, one or two thousand people joined the work.

With so many people, they account for four-fifths of the population of the entire Shoujiang settlement.

With so many people, the canal digging project is progressing very quickly. According to the specifications of six meters wide and three meters deep, hundreds of meters can be dug every day!

…

Drainage is in full swing.

At the same time, Chen Lao's career has also entered a new stage.

With abundant and filtered water, Professor Chen brought out his advanced skills as an agricultural expert!

Professor Chen specially deployed a group of skilled and careful survivors from the settlement as trainees to start growing hydroponic vegetables and fruits!

In view of the large-scale soil pollution in the wasteland, hydroponics is the best choice if you want to achieve vegetable freedom.

However, hydroponics requires very high quality water sources, which Professor Chen had not considered before.

Things are different now.

With sufficient water sources and water purification devices, Professor Chen directly opened up a large-scale hydroponic planting industry in the shelter.

Hydroponics is a delicate job!

First, Professor Chen will call on people to use various sealed containers in the evacuation base to create suitable containers.

Foam boxes and plastic boxes are the best choice for these utensils.

Clean the boxes and various bottles and cans before use, and then prepare the fixing ties and fixing plates.

After completing the preliminary preparations, the second step is to select vegetables suitable for hydroponics.
