He is so stubborn, how can he be such a picky person?

Under Li Su's order, a few more pots and stoves were added to cook everyone's rice.

And the pork I bought was also stewed half at a time.

The practice of pork spread quickly, and in less than a year, it has spread from Chang'an City to Yizhou.

This also aroused the enthusiasm of the people of Yizhou to raise pigs.

However, because pig raising requires a cycle.

As a result, many people like to eat pork, but there is not so much pork in the market.

At present, the price of pork continues to rise.

Everyone was left behind by Li Su, even the children and old people in the village were called over.

And these villagers, except for the New Year's festival or when they eat a big feast, are the first time they have eaten such oily and watery dishes.

Even though it's just a big pot of dishes, they also eat with a mouthful of oil.

And the prince Li Su, who was unattainable in their eyes, actually squatted on the ground with a bowl of rice and a bowl of big pot vegetables, and had lunch with them.

This made the distance between them and the Grand Governor much closer at once.

In the afternoon, Li Su also saw how they drilled salt wells.

First, they dug through the upper layer of earth, a meter or two down, to the rock layer.

At this time, it is necessary to start using the crank.

These workers set up the cart with their hands and feet, and then dragged it around with oxen.

Under the crank, a drill bit is hoisted, and the power of the crank is used to smash the rock one by one.

Soon, a hole will come.

What puzzled Li Su the most was that he used the weight of the drill bit to impact the hole, and Li Su could naturally understand this principle.

To Li's surprise, how did they clean up the debris from the well after it was drilled.

And then, Li Su quickly saw their operation.

It turned out that they used a tool similar to the suction wheel of later generations to suck out the debris directly.

And, according to Qiao Qi, this way of digging wells has been around for a long time, and it has been passed down from generation to generation.

It can be seen that before the Sui and Tang dynasties, there was already a lot of drilling experience in ancient times.

The drilling technology used by the people now is actually the same as that of the ancients, but they used more advanced modern machines.

The wisdom of the ancients should not be underestimated.

……

There is a lot of strength in numbers, and the work of digging wells here is going on quickly.

Li Su estimates that he can drill at least five or six meters in a day.

And, on the first day of drilling, the rock begins to get wet, which is a prelude to the water.

I believe that tomorrow, there will be water.

Of course, it's not enough to just get out of the water.

It is necessary to be able to ensure the amount of salt used.

But Li believes that it only takes four or five days to ensure their initial salt production.

And in the past few days, Li Su simply took Xue Rengui and other guards and stationed them in Xiaohe Village.

If you want to open up the situation in Yizhou, this salt production is a breakthrough.

Even if he went back until the salt production was successful, there was nothing to do.

This time, the convoy once again sealed off the village of Little River.

Of course, because Xiaohe Village is remote, the blockade here has not attracted much attention from them, although it has been suspected by several major families.

Five days went by in a flash.

The salt well has already produced water, and at the same time, the initial salt pond has been built.

The villagers also set up several temporary shacks, which allowed Qiao Qi and others, who were guarding the construction site, to live temporarily.

As for the house, it will take a few more days.

In fact, there are so many people, and the wall has already been built.

But they built a mud embryo room, and they had to wait until the mud embryo was dry before they could top it, which was not in a hurry.

The salt well had already produced water, and in order to ensure that the amount of water in the well was sufficient, Li Su deliberately worked for a few more days.

Now, the depth of this salt well is more than 30 meters deep, which is enough for them to use in the early days.

The next time, they will start making salt.

The first step in salt production is to take water out of the well.

Li Su was quite curious, the mouth of the well was only the thickness of a large sea bowl, and this well was so deep, how did they get the water out of the well before?

Soon, Li Su saw how they fetched water.

They used a bucket that was slightly smaller than the wellhead, but several meters long.

What's even more strange is that this bucket is actually a tube, with both ends open.

After the bucket is placed in the well, it sinks to a certain distance, and then a piece of bamboo falls from the side wall of the bucket, and the bucket is full.

Then this bucket of water is enough to boil a pot of salt.

This method of taking water couldn't help but open Li Su's eyes.

The wisdom of the ancients is indeed not to be underestimated.

However, this method of taking water is not very efficient.

Therefore, Li Su directly exchanged for a pressurized water well system in the mall.

Well, it is estimated that the post-80s generation who grew up in the countryside should have seen pressurized water wells.

The principle of pressurized water well is to use a sealed piston, pour water, press it several times, and use the principle of vacuum to press the water directly from the well.

(A brief introduction, don't expand it, so as not to say smoke and rain, if you haven't seen it, you can Baidu it yourself.) ）

And those villagers, after seeing the parts of the pressurized water well that Li Su took out, couldn't help but be amazed, and didn't know what it was for.

And after Li Su ordered someone to pass the long bamboo into the well, and then closed the upper end, Qiao Qi hurriedly stepped forward to stop it.

This is a salt well, you seal it up, how will you fetch water when the time comes?

And Li Qi smiled slightly, and asked Qiao Qi to step back, and he would naturally understand later.

Next, under the puzzled gaze of the surrounding people, they installed the parts of the pressurized water well according to Li Su's order.

After all the assembly was completed, Li Su lifted the pressure handle of the pressurized water well to the highest position, and then poured a scoop of water into the cylinder of the water outlet.

Next, Li Su went up and down and vigorously pressed the pressure handle.

After a few pressures, Li Su felt that water began to come out of the well.

Boom!

Water from the well gushed out from above, which startled the villagers.

Is this the water that the Governor just poured into it spilled?

At this moment, a shiny stream of water began to flow out of the outlet.

It flowed into the bucket where it had been placed beforehand.

Hey?

Could this be the same scoop of water that the Metropolitan Governor had just poured into it?

However, the Metropolitan Governor had only poured a scoop of water into it, so how could it flow so much now?

And with the pressure of the Metropolitan Governor, the water continued to flow out of the water outlet.

A bucket of water, which was quickly filled.
