After getting rid of the salt merchants, Tang Ping naturally didn't stay in Jiangyou any longer.

followed a group of salt merchants to Fuyi County, and Tang Ping also said that it would take a while to dig a well and cook salt, so he asked each family to take advantage of the fact that the price of the stored salt had not been reduced, and quickly deal with it.

It also makes these salt merchants more grateful.

When I arrived in Fuyi County, the handover of the salt well in the past also seemed to be unusually smooth.

Moreover, in the past, the salt wells of each family were not handed over in vain, and the government gave money.

You can collect cash, and you can also wait for the new official salt to come out to get the salt funds.

Then Tang Ping's pepper seeds were divided, and how to plant them was clearly explained.

There are even several varieties of these peppers, and Tang Ping explained them to everyone in different categories.

Coupled with the brewing technology of bean paste, all the Sichuan dishes I ate that day were handed over to the salt merchants.

Now these salt merchants look at Tang Ping, it is no different from looking at their own people.

When the craftsmen brought by Tang Ping started to work, twenty drilling rigs, more than ten salt wells were made in half a day, and the hand-pressed water wells were connected to the windmill.

When there is wind, the salt brine is automatically pumped up, and when there is no wind, it uses manpower or animal power, and the efficiency is not known how many times higher than in the past.

"Ladies and gentlemen, I heard that there is a fire well around here?"

"There is indeed a fire well, not far from there!" Old man An pointed over there: "But that thing is a bit dangerous, in the past, some salt workers accidentally found that the fire was lit, but sometimes the fire well will suddenly spew out a large amount of fire, if there is a fire source nearby, it will hurt people."

In fact, what they are talking about is natural gas, and Zigong is not only a salt producer, but also the main producer of natural gas in Sichuan.

As for the sudden spewing out of a large amount of gas that Old Man An said, it is a blowout, and if a large amount of natural gas is spewed out at once, if it is not used properly, it will indeed cause danger.

"Take me to see it!"

Tang Ping led people to follow Old Man An, and after turning two corners, he saw an area fenced off, with a sign prohibiting the pillar of fire.

The ancients also knew that this thing was dangerous, especially in the presence of open flames.

"There, there's all sealed, and below that is the original fire well."

Tang Ping nodded, and then asked the craftsman to come over and take a look.

In fact, historically, on natural gas

(This chapter is not finished, please turn the page)

The use has been around since the Han Dynasty, and the Linshao fire well has a history of 2,000 years, but the use of natural gas is quite backward and primitive.

The reason why Tang Ping dared to say that the cost of salt mining in Shuzhong had been reduced to one-twelfth of the original was that it was convenient to open wells and mine brine, and secondly, he found someone to make something that could extract natural gas.

Natural gas is used to cook brine from local materials, eliminating the cost of logging for firewood in the past.

After so many toilets were built in Chang'an City, in order to deal with the feces, Tang Ping found someone to try out the biogas digester, which was just successful before he came out, and the thing that pumped biogas was slightly improved, and there was no problem with using it here to extract natural gas.

Soon, the craftsmen installed a pumping device at the location of the fire shaft, and a long closed pipe was connected to the salt boiling plant on one side.

After opening the valve, I heard the bubbling sound of the swelling after a while, and as soon as the craftsman approached with the fire fold, the red and blue flames ignited.

"It's burning, it's burning!" In the past, of course, salt merchants also tried to use it in this way, but either the gas output was unstable or caused a fire.

After trying a few times, the gains outweighed the losses, and it was better to use primitive wood to boil salt, so the fire well was sealed.

Soon, the extracted salt brine was sent here and the brine began to boil.

As the water is evaporated in large quantities, there is coarse salt precipitation.

In this part, there is not much difference from the salt making process of these salt merchants in the past.

The workers then take out the coarse salt and add some fresh water to make a saturated salt solution, and then use the gauze to filter the impurities.

Then the filtrate of plant ash is added, filtered and re-boiled again and again.

Those salt merchants watched Tang Ping's people operate there, these workers were trained by Tang Ping in Chang'an in advance, and I have to say that their operation is much more high-end than the messy salt works in the past.

When the salt works are fully completed, they will become the foremen here and start training new salt miners.

Tang Ping didn't object to them looking here, in fact, there is nothing to keep secret about the purification of coarse salt, even if these salt merchants have learned, they don't have the technology to extract natural gas and well brine, and the price is still much more expensive than buying from the government, so why bother thankless?

Some salt merchants are so interested now, in fact, they mainly want to know where they are losing, and why Tang Ping can make better quality and cheaper salt.

At this glance, I saw that it was almost dark, and finally a batch of fine salt was made.

When the salt that had been made under their noses was served, several people started to use their hands and stuffed a finger into their mouths.

"There's really no sand!"

"Not as bitter as our salt!"

"Hey, I took it, my Wu Laosan really took it, several generations or even more than a dozen generations of us have dealt with this salt well, and I am stunned that no one has made the salt from Pingguogong."

"yes!" Old man An also looked at the salt well in the sunset with some sigh: "It is also the kindness of Pingguo, and he still thinks about us, if the government digs its own wells to make salt, we will lose in terms of price, and I am afraid that it will not take a few years to close the door."

He was forced by Tang Ping to agree to the bid at the beginning, and now he naturally wants to tell everyone that there is nothing wrong with following Tang Ping, so that his behavior at that time was not only not wrong, but also meritorious.

Tang Ping looked at the plate of salt-like snowflakes in front of him, and he was also relieved, before the things came out, no matter how much he planned, he might not dare to say that he was 100% successful.

Now not only has the salt merchants in Shuzhong been subdued, but the new salt factory for the Tang Dynasty government is also considered a success, and it will be good to wait for more salt wells to be drilled here, and then large-scale salt production.

Of course, Tang Ping can't leave for the time being, this batch of steam engines is here to dig wells, he has to follow, and after the reservation is completed, he can return to Chang'an with the steam engine and the drilling rig.

Now there are two things that Datang needs to keep secret the most, one is gunpowder, and the other is the steam engine.

One is a great deterrent militarily, and the other is a huge role in people's livelihood.

As long as you keep these two things and give Datang a little time, Datang will be able to soar into the sky.

In the remaining days, Tang Ping left some Xuanjia to guard the salt farm, and then took everyone to have a good tour of the mountains and rivers in Shuzhong.

I went to visit Mount Emei and Mount Qingcheng, and of course I also went to Chengdu in Jinguancheng.

Compared with his visit to Sichuan thousands of years later, it has a different flavor.
