Longshan is the capital of Dongyi, where the products are abundant, the land is fertile, the Ming monarch is diligent in governance, and the people work hard, and it has the unique blessing of admiration from all parties, and it would be better if the flood was less.

This season happens to be the rainy season, and the river flood season is beyond the original imagination, half a month ago, not only Longcheng, but even half of the Dongyi river has burst the embankment.

At that time, huge waves tens of meters high came overwhelmingly, purging most of the cities and villages of Dongyi, collapsing countless houses, and flooding livestock that had no time to escape, displacing people, shortages of food, and banditry.

As the great leader of Dongyi, Gao Tao cared about the suffering of the people, personally inspected the disaster, commanded the flood control on the front line, distributed grain reserves, and did not forget to curse a few words in the upper reaches of the river.

Because of historical reasons such as the Battle of the Deer and the problem of flooding, Dongyi and Huaxia have not been in contact with each other for hundreds of years.

The flood brought disaster to Dongyi, as well as a dying teenager who was lying on a floating plank and unconscious.

As the flood waters receded and the road was muddy, a servant scooped up the water from the pond with buckets and washed the ground, making the bluestone road on the ground show its true color.

Squatting by the pond was a boy who had just woken up, staring at the water in the pond.

Two servants stood not far away and looked at the young man, and one of them lamented, "He can't be stupid, staring at the pool in a daze without saying a word." ”

"Shhhh Another servant stopped him, and all strange people, good and bad, are not to be messed with.

The young man's eyes are double pupils, that is, there are two pupils in one eyeball, and he does look like an alien, but fortunately, he belongs to the heavy pupils, and most of the two pupils coincide, so it is not too terrifying, but when he woke up and opened his eyes, he was still startled by his life-saving benefactor Gaotao.

Yao Chonghua desperately widened his eyes, trying to see his appearance clearly in the rippling and blurred pool water, but no matter how big he stared, the extra pupils in his eyes would not disappear, and he sat directly on the ground in frustration。。。。。。

Yao Chonghua's real name is not Yao Chonghua, nor is he called Yu Shun, but Li Fenghua, a future pillar of the 21st century, but unfortunately this wish died just half a year after graduating in his senior year, and he has not had time to serve the great motherland.

At that time, he entered the society with hope, but he didn't expect the society to give him a heavy slap in the face, because of his unwillingness to integrate, he unfortunately became a scapegoat and added a prison sentence in vain.

On the first night of his cell, he did not sleep well until the second half of the night, when he was already lying on the board, but unfortunately he did not have the strength to struggle and cry for help, and used the last strength of his body to grasp the board, so as not to fall into the raging flood.

When he was in a coma, a person appeared clearly in his mind, surnamed Yao Chonghua, his father's alias was Shun, very thin, a pair of innocent and weird eyes staring at him, he said that he was dead, and asked Li Fenghua to live instead of him, and help him take care of his parents in the future and complete his unfulfilled filial piety.

There is still a little memory of this boy in his body, about ten years old, although he is the son of a tribal leader, he does not seem to be doing well, his mother is a very good person, but his second mother makes things difficult for him in every way with his father's favor.

And the reason why Yao Chonghua fell into the flood was because the flood also washed away his tribe, because he was a heavy pupil and a stranger, so it became an ominous sign, Erniang took advantage of his mother's absence, colluded with Wu Zhu to bewitch his father, so he dedicated Yao Chonghua to the unwarranted river god, the child trembled and grabbed a floating plank, desperately looking at the tumbling water and the hometown that was getting farther and farther away, this Erniang is really ruthless.

According to medical terms, the double pupil is not ominous, but a kind of adhesion distortion of the pupil, generally the four pupils can see the real thing, easy to see the eyes, fortunately, Yao Chonghua's pupils are relatively close, but it does not hinder daily life, this is a point that he is quite satisfied with, but unfortunately there is not even a mirror that can see the face clearly in this era, and he still wants to see how much his appearance has changed.

In primitive society, there is still a little bit of bronze, even less iron, and the mirror is not even to think about it.

Youyu's family was in the upper reaches of Longshan, and Yao Chonghua, who didn't even accept the river god, drifted down the water all the way, and was picked up by Gaotao in Longshan.

In the evening, Gaotao went home, and after coming back, he didn't eat, and a strong man with a long beard paced back and forth in the yard, looking very anxious, so that people couldn't ignore it.

Yao Chonghua took the food that the servant gave him like a nest, but the material was very rough, but at this time, he still cared about what to do, and some of them were good to eat, he just wanted to gnaw, but found that Gaotao was staring at him, did Gaotao think that what he had in his hand was more delicious? This made Yao Chonghua a little embarrassed, if you don't eat, you'll be hungry, let's eat, it's estimated that you will have indigestion if you are stared at all the time.

In the end, Yao Chonghua felt that since he was his life-saving benefactor, he couldn't let the family be greedy, so he divided the nest head into two halves, Yao Chonghua walked into Gaotao, raised half of the nest head above his head, and gave it to Gaotao.

Gao Tao was slightly stunned, took Yao Chonghua's nest head, picked him up, and made it to the steps with a little moss on the side, still with a sad face.

Yao Chonghua was very uncomfortable being held just now, he hadn't been held like this for at least 18 years, fortunately he was still a child now, and he also alleviated the embarrassment, looking at the nest head in Gao Tao's hand, his stomach growled, why didn't this person eat the nest head?

Gao Tao also heard the sound in Yao Chonghua's stomach, and felt that children were good, carefree, and could eat enough every day, so he broke a little nest head and gave it to Yao Chonghua: "Now I can still eat steamed cakes here, and the other people don't know if they are eating hot rice and clean water now." ”

Yao Chonghua grew up in a relatively arid place, and even if there would be a flood, his family would not be able to flood, and he only knew roughly that after the flood, he would first save people while fighting the flood, and then give the victims basic supplies to support their lives, and by the way, prevent the occurrence of the plague.

"Is there a shortage of clean water right now?" He looked up and said with a puzzled look on his face.

"Yes, although there is a lot of water now, the mud and wood in the flood have muddied the water, and there are still soaking animal carcasses in some of the water, and there is very little well water left." Gaotao is very helpless, there is little food, but each tribe has its own tun, but clean water is difficult to solve, the only way is to put dirty water into the clay pot, slowly wait for him to settle. However, the volume of the clay pot is very small, the precipitation time is long, the clay pot is fragile, and there are not many people who can move the clay pot out of the flood, which is simply not enough for the entire tribe.

Yao Chonghua remembered that when he was in class, he knew that there were four ways to turn dirty water into rushed water: precipitation, filtration, adsorption, and distillation.

Sedimentation is the most primitive and worst method, can remove large particles of sediment, small particles of it takes longer, now in the living environment, there must be a lot of bacteria and parasites in the water, if you drink such water, you may have a stomachache in the later stage, and even cause a large-scale plague. But Yao Chonghua also doesn't know where to find some substances such as alum and activated carbon that already exist, the cost of ready-made activated carbon and distilled water is too high, and it is obviously not suitable to use it at this critical moment, but if there is really an epidemic, it will be a human life, he can't bear it, so he can only use the simplest way.

Yao Chonghua told Gaotao: "You can filter the water and boil it, so that the water will become clean, most of the bacteria and parasites in the water will die, you can reduce the chance of plague, and drinking more hot water is good for the stomach." ”

"Boil water? Bacteria and what? Gao Tao was puzzled, what were those things.

Yao Chonghua broke free from Gaotao's body, scooped up the water from the pond with a jar nearby, put the cloth on his body to the mouth of another clay pot, poured the pond water into it, so that most of the particles were isolated, and then ran to the kitchen to put the clay pot on the fire, and when the water boiled, it would condense some of the originally more subtle suspended solids, and after filtering it once, it would be almost the same, and most importantly, most of the bacteria in this way must be gone.

Gao Tao has been following Yao Chonghua behind, see his actions are very simple, and when he saw the water that Yao Chonghua gave him, he felt that he was really stupid, usually they drink raw water in addition to cooking, but never knew that heating water can make dirty water clean, he used a pottery cup to take a little Yao Chonghua boiled cooked water, sure enough, there is no granularity of sediment, there is no peculiar smell, a cup of hot water to drink, the stomach is warm.

Gao Tao was delighted: "How do you know that this can purify the water?" ”

Yao Chonghua said, "I...... My mother taught me. ”

"Does this really reduce the number of plagues?"

Yao Chonghua nodded.

"Your mother is really a smart woman, she and you have done a great job for us Dongyi." After praising Yao Chonghua a few words, Gaotao hurriedly went out, as if he wanted to vigorously promote this plan.

Yao Chonghua watched Gaotao go out, continued to squat on the steps and nibbled on the nest head, or steamed cakes, staring at the sunset in the west, falling into deep thought.

He is very grateful to have a chance to be reborn, but it is in ancient times, which is really funny, he is a modern person, adapting to the life of modern people, and in ancient times, even if he has a reserve of knowledge that they do not have, so what? After crossing over, he is still an insignificant ant whose fate is held in the hands of others, and he will be hungry, injured, and afraid of death.

However, Yao Chonghua is not a literary scholar who can only be sad and sad, his temperament is even a little straighter, a little stronger, otherwise he will not go to prison, but he is not arrogant and high-minded, but he is just a little more principled, but in the eyes of those people, he just doesn't know the times, but there is hope in life, he hopes that he can escape from the clutches of fate in this life and create the future with his own hands.

The only thing that the person named "Yao Chonghua" asked him to do was to be filial to his parents, that was a poor man, his last wish must be fulfilled by himself, and then think about himself, his father died when he was very young, and his mother pulled him up alone, and he didn't know how sad his mother should be after he was imprisoned, she should be disappointed in herself, and she can't be filial to her old man in the future, how should she live?

Now the first thing he wants to do is to go back to Youyu's to find his parents, by the way, he will sacrifice him to the river god Erniang, he wants to see, what kind of person can be so ruthless, but he doesn't know where Youyu's is at all, and he doesn't know how to go back, he has to think of a way.
