I am a primitive

As long as you dig deep enough, you can dig water even in the desert.

Instead, I worry about whether the groundwater dug is good or not.

Groundwater is a wonderful thing. Sometimes the water coming out of two wells that are no more than ten meters apart will taste completely different.

Some taste good, and some not only taste bad, but also leave a layer of powder after a little cooking in a pot.

It is precisely because of knowing this situation that Han Cheng appears more disturbed.

If the well dug in the tribe smells bad and there is a lot of sediment after boiling, he will definitely ask someone to fill it up and dig another well.

After all, this is a matter closely related to health.

In this era of lack of medical care and medicine, Han Cheng will try his best to avoid things that are harmful to health.

And water with too many impurities is obviously a kind of existence that is harmful to the human body.

Not to mention the rest, just the kidney stones alone, once you get it, it will be enough for people to suffer.

Compared with the health of everyone in the tribe, spending more energy is nothing at all.

Thinking of kidney stones, Han Cheng suddenly remembered a very strange post he had seen before time travel.

Posts are -- you know what?In fact, human beings have never stopped evolving, but they have all been cured by doctors.

Just looking at the post, I don't think there's anything wrong with Qingqi, the key is that with the reply from God below, everything becomes alive.

To be a netizen who suddenly realized - so the golden core in my body was picked up by the doctor as a stone!

It's funny, but Han Cheng doesn't care about golden pills like stones at all, and he doesn't want them to appear in his body. This thing is really painful, the kind that can kill people when it hurts.

During this kind of waiting, the water in the ladle and the jug could not be cleared. After waiting for a while, when the water in the ladle became a little clearer, Han Cheng finally couldn't wait any longer.

He picked up the muddy water and brought it to his mouth to take a sip.

The well water that has just been extracted from the ground for a short time is cool and sweet after entering the mouth, with an excellent taste.

Han Cheng, who had always been a little worried, was relieved at once.

"Son of God, is it good to drink?"

Surrounded by Wu and others watching Han Cheng drink water, they looked at Han Cheng expectantly and asked impatiently.

Han Cheng didn't answer everyone's words, but spit out the water in his mouth first.

Everyone who watched such a scene was full of anticipation, their hearts sank involuntarily.

This water must not be very tasty, otherwise how could the Son of God spit it out?

"It's delicious! It's very delicious! You all have to try it!"

Han Cheng, who spat out the well water in his mouth, enthusiastically praised the taste of the well water to everyone in the tribe.

It seems that later generations have listened to all kinds of propaganda. After traveling to a so-called A-level scenic spot, they were disappointed. When they came back, faced with the inquiries of colleagues, they immediately felt that the trip was worthwhile, and began to talk happily. It also fools unscrupulous people who have experienced it in the past.

"Just drink it in your mouth and taste it. Don't swallow it. The water has not been clarified, so you can't drink it yet."

Han Cheng added.

After these words were uttered, the surrounding people who were puzzled by this suddenly realized.

It was so!

Dang even took the ladle handed out by Han Cheng, facing the well water that was still a bit muddy, you tasted it one by one.

After tasting the sweetness of the well water with their own mouths, everyone's faces were covered with smiles, and they were beyond happy.

After the well on the kitchen side came out of water, about half a day later, the well next to the barn in the outer courtyard also came out of water, which made everyone in the tribe very excited.

And Han Cheng, while letting people scrape the water out while continuing to deepen the well, he also asked some people in the tribe to transport stones from the quarry to the tribe.

These stones are used to surround the well after the well has been dug thoroughly.

The so-called ring well means that after the well is drilled, a platform that can support stones, bricks and other things is dug out on the wall of the well at a certain distance from the bottom of the well. The behavior of building circles against the wall of the well.

A well surrounded by stones can effectively prevent the soil on the well wall from collapsing and prolong the service life of the well.

Moreover, the well water can also be kept clean to a certain extent.

Under the guidance of Han Cheng, the son of God who only moves his mouth but does not work hard, four days later, the two wells of the Qingque tribe were completely built.

On the top of the wellhead, a large stone slab weighing about seven or eight hundred catties was used for suppression, and the round wellhead was built into a square shape, and a potter's wheel was mounted on the wellhead, which was very similar.

"Bring the fish."

Han Cheng lay on the edge of the well and looked into the well. The water below reflected a small sky and half of his silhouette.

There is already a lot of water in the well, and you can put fish in it.

After hearing Han Cheng's greeting, the second senior brother came over with a water basin, and there were four carp about a bunch long in the water basin.

The color of the carp's tail and fins is reddish, and there are beards around the mouth.

Han Chengcheng reached out to fish out two carps from the water basin, grabbed one in each hand, and threw them both into the water gently at the same time.

When the fish came into contact with the water surface, they made some noises, and circles of ripples appeared on the calm water surface.

As for the two carp that came into contact with the water again, they just swung their tails and disappeared into the water.

After lying here and watching for a while, Han Chengcheng and the second senior brother who was carrying the basin went to the well in the outer courtyard, followed the same pattern, and put the remaining two carp into it.

Looking at the carp that disappeared, Han Cheng smiled.

Of course, this is not expecting how many years later, a few carp will transform into dragons and become the existence of protecting the tribe.

It was because he remembered the effect of putting carp in the well.

On the one hand, carp live in it and can eat the worms and some worm eggs produced in the later years, so that the well water can be kept as clean as possible.

On the other hand, carp can be used to judge whether the water quality in the well is bad enough to eat dead people, and it can also effectively prevent people from poisoning the well water.

Of course, this standard needs to be measured by the life of carp.

As for why two fish were put in instead of one, it was because they were worried that one fish might die in some accident, and one more fish would be more insurance.

In addition, it is too lonely for a fish to live in a well, and it is easy to suffer from depression and autism. How can two fish live happily together.

Of course, as for the two carps that were put into the well together, whether they were a male and a female, or two fish of the same gender, Han Cheng didn't think too much about such details...
