Rebirth 1978, Wife, I won't go back to the city

"The director said no money is needed!"

"That won't do! Let's put it this way. The price should be the same as the price!"

Under Li Jingshen's insistence, the other party had to state a price.

The price is indeed a bit expensive, but Li Jingshen is very satisfied and feels it is worth it!

"Then I'll go back first!"

The other party took the money and drove away in a hurry.

It took a full three days to dig a well of fifteen meters, which had already met Li Jingshen's psychological expectations.

During this time.

Jiang Guoli couldn't sit still either, so he ran to the well to help, pouring out the mud and so on!

After the construction of the well was completed and the water settled for a night, Li Jingshen pulled the water pressurizing device and arrived next to the well.

Jiang Guoli saw what Li Jingshen had brought and asked with a puzzled look on his face, "What did you get here?"

Li Jingshen said with a smile: "A water pressure device used to pressurize water!"

"What?"

Jiang Guoli became increasingly puzzled and shook his head, saying, "I've lived for so many years, and this is the first time I've heard of a water pressure device. What exactly is this thing used for?"

Li Jingshen smiled mysteriously and said, "Wait until I put it on, and you'll know what's going on!"

"Install it? Where to install it?" Jiang Guoli looked confused.

Li Jingshen didn't respond to Jiang Guoli's words. He turned to look at Jiang Shu and said, "Third brother, come over and help me put this thing into the well!"

Jiang Shu ran over happily and cooperated with Li Jingshen to insert the steel pipe into the well.

When the steel pipe entered the well, there was still about one meter of space left, so Li Jingshen used a sledgehammer to pound it down.

Only after the steel pipe completely sank below the wellhead did Li Jingshen let out a breath and wiped the sweat from his forehead.

Jiang Guoli became increasingly confused and asked, "What on earth are you trying to do? How are we supposed to get water if this thing is blocking the well?"

"Don't worry! I haven't finished yet!"

Li Jingshen took out the well pressure head, which consisted of a handle and a pressure plate. It was already formed and very easy to operate.

After everything was ready, Li Jingshen began to fill the soil and completely secure the steel pipe.

Jiang Guoli couldn't understand Li Jingshen's actions and couldn't help but ask, "What on earth are you trying to do? We finally dug a well, why are you blocking the wellhead?"

Li Jingshen didn't know whether to laugh or cry, and said patiently, "Dad, just believe me! How can I really be so hard on myself?"

"Okay! Take your time and try it yourself. I want to see what you can come up with!"

Jiang Guoli rolled his eyes, too lazy to say anything more, and just watched silently.

Seeing Jiang Guoli's angry look, Li Jingshen was even more amused and said, "Dad, I'll show you what a water pressure well is!"

He immediately grabbed the handle of the water pump and squeezed and shook it up and down.

A sound soon came from inside the steel pipe!

Li Jingshen increased his speed and strength. As the sound in the steel pipe became smaller, a stream of water gushed out.

"Huh? This..."

Jiang Guoli was stunned.

How come water came out after just pressing it a few times?

When Li Jingshen saw the shock on Jiang Guoli's face, he laughed secretly in his heart.

In fact, water pressure wells are not a high-tech invention. They were developed in ancient times.

However, due to problems such as casting technology, the use of water pressure wells was very limited in the past.

This kind of niche place cannot be spread on a large scale, so many people don’t even know about the existence of water pressure wells.

Although the casting technology of this era can already meet the needs of large-scale distribution of water pressure wells.

But the materials and prices of pressurized wells alone deter most ordinary people.

When the price of steel dropped, cities started to have running water again, and rural areas had various water pumps to pump water, there was no need for this kind of artificial water pressure wells, so this kind of water pressure wells were naturally gradually eliminated by the times.

But it must be said that for Jiang Guoli, who had never seen such a thing, this thing was definitely novel enough.

He quickly took a bucket, placed it in front of the flowing water, and tried it himself.

Seeing that he had filled a bucket with water with just a few pushes, Jiang Guoli was surprised and said with a smile, "This is so easy! It saves a lot of effort compared to just using a bucket to draw water!"

"But how does this thing work? Why can I pump up water from a depth of over ten meters just by pressing this handle a few times?"

Li Jingshen explained with a smile on his face: "It uses the principle of air pressure to pump the water directly from the well!"

Jiang Guoli couldn't understand such profound words at all. He said, "You must be the educated youth from the city! You speak so profoundly. We illiterate people can't understand a word."

"Dad, what don't you understand?"

At this moment, Jiang Xue came over with Tuantuan in her arms. Seeing the water pump in front of Jiang Guoli and Li Jingshen, she asked in surprise, "What is this?"

Jiang Guoli laughed heartily and said, "This is some kind of water pressure well that Depth of Field made. Just press it a few times and you can fill a bucket with water. Come over and try this good thing!"

Jiang Xue handed Tuantuan to Li Jingshen, and then pressed the handle a few times according to Jiang Guoli's instructions.

as predicted!

It only takes a little effort to fill a bucket of water, which is very easy.

"Bah, bah, I want to try it too..."

Tuantuan was also very curious when he saw such a novel thing.

"Tuantuan is also okay?" Jiang Guoli frowned.

"can!"

Li Jingshen put Tuan Tuan down and signaled Jiang Xue to let Tuan Tuan try.

It’s true, this little girl is young but very strong.

Although every time you press the handle, you need to use all your strength.

But Tuantuan can indeed use the water pressure well to draw a full bucket of water!

"I'm so tired..."

Tuantuan fetched a bucket of water and was extremely tired. He opened his arms and threw himself into Jiang Xue's arms.

Jiang Shu also tried it excitedly, and then he and Li Jingshen filled the water well completely.

"Dad, if you need water in the future, you can come here to get it. The well I dug is deep enough. It is enough for the small pig farm now. When the pig farm grows bigger in the future, we can get a water pump to pump water, which will be more convenient!" Li Jingshen said.

Jiang Guoli nodded, looked at Jiang Shu, and reminded him, "Third brother, don't show this thing off. Although it is indeed very useful, you can't tell others, otherwise you will definitely get into trouble!"

Jiang Shu shrugged and said nonchalantly, "Dad, what's the problem with this? The pig farm was built with the approval of my uncle, and the well was built after getting approval. Can the village take it back?"
