However, it takes 200 points of soul energy to upgrade from [Level 0 to Level 2] to [Level 0 to Level 3]. Bai Yuqi's remaining 78 points of multi-soul energy are obviously not enough to upgrade.

Fortunately, Yang Tieniu slaughtered another sheep at this time, and the soul energy he absorbed was just enough for him to level up again, which once again increased the upper limit of mana by 320 points. As a result, his upper limit of mana directly exceeded the 800 point mark!

But when he wanted to upgrade again, he saw that Yang Tieniu had already called the villagers for help, hung up a pig and a sheep, and was about to start disemboweling them.

Bai Yuqi asked strangely why he didn't continue killing.

Yang Tieniu was stunned and said that one pig and one sheep were enough to feed everyone in the village.

When Bai Yuqi looked at the lean pigs weighing hundreds of pounds and the sheep weighing dozens of pounds, he felt that the meat could not be divided into a pound per person, so he asked him to kill a few more pigs. He wanted to have a good meal, right?

But the old villager was crying and rushed over, hugging the sheep dragged by the villagers, and refused to let go as if it were his own. He even beat and kicked the villagers who caught the sheep away.

At any rate, the old villager disagreed and said he was killing sheep to eat meat, but there was no reason to eat only meat. What kind of fairy life was this?

You must know that in the past, even during Yuanchen, that is, during the New Year, there was no meat or fish. The villagers, including Yang Tieniu, were scolded and wanted to go to heaven after only living a good life for a few days!

Well, Bai Yuqi, who couldn't resist Lao Cunzheng, retreated. Considering that it was not easy to preserve meat without refrigerators these days, he could only kill it another day.

Bai Yuqi, who had more than 800 mana points, was not stingy with his mana. He used [Water Making Technique] to create several large vats of "fairy water" and kept them for making soup when cooking meat.

Then he summoned his mount and asked Gouzi to take him to the Bitter Spring Salt Field behind the hill.

While Bai Yuqi was busy building a villa for herself, the villagers were not idle.

In addition to taking care of the few acres of thin farmland in the village, the rest of the time, under the leadership of the old village leader, the whole village boiled salt day and night.

Not only did they knock out all the brine on the rock walls around the Bitter Spring, they even dug up the mud around the Bitter Spring to wash and filter the salt, which expanded the area of ​​the Bitter Spring a lot, making it look a bit like a small pond.

Yeah, that's a lot of energy.

But Bai Yuqi can also understand the enthusiasm of the villagers.

A village that can cultivate some thin fields, collect some mountain products, and hunt some wild animals, but its only output is a carbon kiln that is laborious and does not make any money.

Suddenly having a pillar industry like salt mine, why don't the villagers work hard to make a good life?

The spring of Bitter Spring is actually very small, and the salty brine gushes out slowly.

Being fucked like this by the villagers, not only all the accumulated salt brine and salt mud were used up.

The gushing brine has only half filled the bitter spring that has expanded several times... No wonder the old village is taking the villagers to rest today.

After thinking about it, Bai Yuqi decided to improve the way of making salt.

First use [Turn Mud into Stone] and [Stone Shaping Technique] to build the saline-alkali land around the bitter spring into a regular pool.

Then, a series of stepped reservoirs were built along the mountain below the bitter spring, and "fossils are sand" were used to fill them with thick fine sand for filtration.

Immediately below the "sand filter", several connected "charcoal filters" and a "salt water pool" were built.

In this way, a large number of manual processes can be omitted, and only the charcoal in the "charcoal filter" needs to be regularly replaced, and the salt water must be taken from the "salt water pool" to boil salt.

Since filtering salt requires a large amount of charcoal, Bai Yuqi simply built several tandem carbon kilns under the salt water pool.

At that time, a thin iron pool for boiling salt will be installed on the top of the carbon kiln, and a fire will be made to suffocate the carbon below to avoid wasting heat, killing two birds with one stone.

The only problem is that it is not easy to build a large enough iron pool. At least it cannot be built with the iron-smithing skills of the villagers in Kushui Village. They can only use [Steel Rock Technique] and [Solid Rock Mass] to strengthen the thin pool first.

Slate instead…

System projection: [Recommended activation spell: [Metal Dissolution]]

"..."

Bai Yuqi was just thinking about it.

The Eternal Endless System appeared unwillingly and recommended a spell to him that could solve the problem.

Bai Yuqi was speechless and said: Thank you! This spell is not cheap, right?

As expected, activating [Metal Dissolution] requires 100 points of faith.

Although Bai Yuqi has more than 500 points of faith saved, it is enough to activate this magic skill.

But the Eternal Endless System was so attentive and recommended a large number of skills to him, but it still made him feel like he was being forcibly sold insurance.

The carbon kiln hasn't been built yet, and there aren't that many iron materials in the village, so there's no rush to activate it.

Bai Yuqi thinks that the spring under the Bitter Spring should be expanded to increase the output of underground brine.

In addition, he estimated that the creek from which Kushui Village draws water should be affected by the brine overflowing from the Suffering Spring over the years, causing the nearby land to contain a large amount of salt brine, so it becomes bitter.

If the stream can be diverted so that it no longer passes through the salt brine land in the Bitter Valley, the water should not be bitter.

Therefore, Bai Yuqi asked the dog to carry him upstream along the creek for a while, and tasted the water along the way.

Sure enough, starting from a few hundred meters away above the bitter spring, the water of the small stream flowing out of the mountain began to become extremely sweet.

According to Gouzi, this stream actually flows from a small cave a few miles away.

Bai Yuqi deduced that the groundwater connected by the creek should not be in the same branch as the groundwater below the bitter spring.

Or there simply is no salt deposits that may exist deep underground, formed after the ancient underground sea dried up.

That's why in the same mountain, some water is bitter and some are sweet.

In order to solve the water problem in Kushui Village, Bai Yuqi asked his dog to carry him several miles up the mountain road and found the cave where the water came from.

After some exploration, I found that the cave was not deep. The so-called cave was actually just a small hole that was eroded by water and was only half a person's height.

Taking advantage of his small size, Bai Yuqi got into the cave and confirmed that the water source did come from an underground water outlet in the cave. Then he used [Fossils to Mud] and [Mud to Stone] to expand the cave into a storage tank.

pool.

The entrance to the cave was sealed, leaving only a stone water pipe made with [Stone Shaping Technique] to lead to the outside, thereby protecting the spring water from being polluted during its flow.

Then, the stone water pipes were shaped along the way, taking a straight line to the direction of Kushui Village. Along the road, mountains were dug and bridges were built at every ditch, creating an elevated water channel to divert the water.
