After retiring from the dynasty, Win Changsheng ignored these ministers.

He has his own things to keep busy with right now.

Now, he wants to take a look at the pressurized water well he tried to make, has it been completed!

Ten miles outside Xianyang City, Ying Changsheng is located in the salt well at the foot of Baigu Mountain, at this moment, when the latter arrived, he only saw that Gong Lose Shangzao had arrived early, and even his sister Gong Lose Prajna was also waiting there, but he saw that Gong Lose Shangzao said to Win Changsheng with a happy face.

"Nineteen sons, are you here?"

"Well, the casting of the pressure well itself, has the casting been successful?"

Win Changsheng nodded, jumped off the carriage, left Liu Bang behind him, and then walked forward quickly, and asked Gong Shangzao.

The latter hurriedly replied.

"Of course, the casting was successful, and the piston we made with glue was also successful, and it is now being assembled!"

"Oh?"

Ying Changsheng's eyes lit up, his face was happy, and he hurriedly said.

"Then assemble it quickly, install the water pipes and pistons, install them in the well, and try to see if you can get the water out!"

Ying Changsheng said.

A water presser is a good thing.

If it can be successfully produced, it will be a good thing for the benefit of the country and the people.

After listening to Win Changsheng's instructions, he hurriedly instructed the craftsmen next to him to speed up, and after a short time, the water pressure was successfully assembled, and then connected to the bamboo water pipe that was five or six feet long.

Then, I saw Gongyi Shangzao, personally went into battle, and shook the steel handle on the well water vessel by himself, shaking it more than a dozen times, but only saw that there was no water pumped up in the well, which made Gongyi Shangzao frown, and then asked Ying Changsheng next to him.

"Nineteen sons, what's the matter, can't you hit the water? Could it be that this is because, what is wrong with our production? Or is it that this line of thinking doesn't work? ”

The public loses the theory of creation.

Win Changsheng laughed out loud, he remembered the steps he had to take before using the water pressure at home when he was a child, and he couldn't help but explain to his father.

"This water press, that's not how it is used!"

"That's?"

The public loses and makes a confused face.

Is there anything else to say about this use?

Isn't it just the lever of moving up and down back and forth?

What else makes sense?

Gong lost and was puzzled, but Win Changsheng ordered someone to bring a bucket of water.

The people under him didn't know why, and they thought that Ying Changsheng was going to drink water, so they hurriedly asked.

"The nineteenth prince wants clean water, this is not easy to get, we are a salt well, there is a lot of salt water, if the well water is used, the water in the tank is used up, you have to go to the creek a few miles away to fetch water......

"No, no, no, any kind of water is made, as long as it's water, even if it's dirty water!"

Win the Immortal Dao.

When his subordinates heard this, they were immediately overjoyed, and after a while, they brought a bucket of brine to Ying Changsheng from the salt well next to him, but he only saw Ying Changsheng, poured the salt water into the water press, and then went to the next Gong to make a road.

"Try again and see if you can get water!"

"Okay, try it!"

Gong lost and hurriedly said.

Immediately, I tried to press the lever on the water press.

I saw that a far more shocking scene appeared.

In the public transport back and forth to make seven or eight hands, in the water press, there is a large amount of water, each press, a large stream of salt water, will be through the casting of the water outlet, gushing out, just three or two, the water pressure under the interface of the bucket, it is full of brine!

"It's amazing!"

The workers in the salt well on the side exclaimed.

This is truly a god!

The simple lever principle, gently press a few levers, you can pump up the well water, and, looking at the efficiency, it is still quite high!

The public on the side was also shocked, and he exclaimed.

"This, that's too easy, isn't it?"

"The lever of this water pressure can be moved by ordinary children!"

"That's natural!"

Ying Changsheng couldn't help but smile and said.

"The principle of this lever is sitting there, four or two thousand pounds!"

"Nineteen sons are right!"

Gong lost his jaw head, and then, after looking at the water press, he muttered.

"However, people will be tired after all, and after thinking about it, you can get a cow, use it to design an animal power transmission structure, and use the ox to draw water......"

"In this way, you can pump water continuously, and, the minister pondered, the common people, can also promote this thing, this thing is not too troublesome to make, and, with this thing, the people are much more convenient to drink, not only that, usually in the case of drought, you can also use this trick to pump water from the ground to irrigate the farmland......"

"That's right!"

Win Changsheng said, and the public lost to the building, probably attracted by the water press.

At the moment, I'm having fun there.

It's a lot of fun!

And Ying Changsheng saw that the problem of drawing water was solved, and he also began to give an order to try to make refined salt!

The production of refined salt is nothing more than purification.

It's simply very, after Win Changsheng taught, several craftsmen instantly understood the truth in it.

One by one, they quickly began to use brine to extract the refined salt inside.

And while they're doing that.

Win Changsheng set his sights on the production methods they used.

Suddenly, Ying Changsheng frowned.

"What, is it boiled salt? Why not use salt? ”

"Salt?"

Everyone was stunned for a moment, and then, Chao Ying Changsheng smiled bitterly.

"The nineteenth prince doesn't know, if you dry salt, it's too much of a waste of time, and you can't produce a finished product for a while, and if you dry salt, you have to level the land and make a reservoir, our salt, including the Qi country, is also a salt sea for salt......"

"It's easy!"

Ying Changsheng laughed.

"The land for drying salt is very easy to do, and when we wait until the cement is made, let's build a few salt drying fields here?"

Well, the biggest problem with salt drying in the current era is that.

Salt in the mud.

It's so hard to get.

Salt water is likely to seep directly into the soil, causing the soil to become salinized, and the same amount of water cannot be produced with the same amount of salt.

In addition, the salt was dried in the mud to produce a finished product, and the salt inside was very dirty because it was stained with soil.

With cement paving, making cement is different.

The salt water will not seep down.

It's just a little slower.

However, it's okay to be slow!

Compared with boiled salt, the cost of drying salt is very low!

No fuel, no manpower, the cost savings are not comparable to boiling salt!
