Liu Chun almost wanted to cry, Zhu Yuanzhang saw him once, scolded him once, handed over the most bitter, tiring and offending things to him, and was stingy with rewards, look at those officials from the imperial examination, within a few years of hard work, some people have mixed up with the squire. He's good, it's taken a lot of effort, and he's still a little bit of a homonym, and it's a shame to say it!

"You also said that it was sent to the Imperial Prison, it was done by Jinyiwei, it has nothing to do with me, you know?"

Xu Zengshou rolled his eyes and said, "What are you pretending to be innocent?" What's your dad's position? ”

Liu Chun almost forgot that his father seemed to be a fellow acquaintance of Jinyiwei! Also deputy. The two of them are so pitiful, why don't they make a bet with their father to see who can straighten things out first.

Not bad...... At present, the prefect of Changsha is vacant, and the commander of Jinyiwei is Jiang Xuan. That guy is honest and yin, and he does things without leakage, and with the thick lines of the third master, it is not easy to bring down Jiang Xuan.

So, the odds of winning the game are still big.

Bet!

Liu Chun thought as he retorted to Xu Zengshou.

"My father is a righteous gentleman and will not frame the innocent!"

Xu Zengshou didn't believe it, "Let's tell the truth, no matter how kind the third master is, if someone wants to harm his son, can he let it go?" I can see through it, Zhan Hui will definitely die! Tsk, this guy is the longest-serving official in the Ministry of Heavenly Officials over the years, but I didn't expect it to fall into your hands, I obeyed! ”

Xu Zengshou raised his neck and said very seriously: "Big brother, you can teach me the art of officialdom again!" Little brother wants to learn more from you! ”

Xu Laosi finally remembered that he was still a younger brother!

Facing this younger brother, Liu Chun had only one word: "Phew! ”

……

On the second day after entering Beijing, Liu Chun was called to the palace, and he entered the palace early in the morning, and he didn't even have time to eat.

"Come on, the prince is gone, and there is no one to accompany me to breakfast." Lao Zhu Nian chattered and asked the eunuch to move a pier for Liu Chun. Liu Chun thanked him and sat down.

Zhu Yuanzhang's food has never been very good. White porridge, side dishes, meat steamed buns, spring rolls, just a few old things.

"Would you like a plate of crab roe lion heads?"

Liu Chun hurriedly waved his hand, "Enough, enough." It's already hearty. ”

Zhu Yuanzhang laughed, "Don't coax me, there are many people who can eat tricks!" I have heard that in the homes of some ministers, a casual crab feast can eat ten taels of silver...... If you don't eat crabs, you can be full just by feeding the silver! See, I'll feed them the money in the future! ”

It's full, not only full, but never hungry.

Lao Zhu is as jealous as ever, Liu Chun just eats with his head bored, and Lao Zhu has a match to say.

When he was almost done, Zhu Yuanzhang turned to the topic, "How is the livelihood of Changsha?" Can all the people eat...... Gruel? ”

Liu Chun hesitated for a moment and shook his head, "Your Majesty, there are almost ten percent of the people, and they only eat one meal a day. ”

"A meal?"

"Hmmm! This is especially true when the farm is not working...... The minister calculated that the people of Changsha Mansion only have five or six acres of land per person on average, and some poor families have only ten acres of land, and after paying harsh taxes and miscellaneous taxes, the remaining rice, at most, is five stones, threshed into rice, three stones and five buckets, a pair of parents, plus a few children, spread to each person's head, and only two or three taels of grain a day, boiled into porridge, barely survived. ”

"Fortunately, I relied on water to draft water, caught some fish and shrimp, sold them for money, subsidized the family, and paid taxes. But it's not easy to fish, not to mention those who drowned, just the water Gu disease can make many people miserable, this time in Changsha Mansion, I saw no less than 500 patients, many of them have big stomachs like grinding plates, but they are emaciated and haggard, and their faces are turmeric, like water ghosts! Moreover, most of the sick people are young and strong laborers, who have been in the water all year round and have been contaminated with water Gu, so it is not surprising. Often one person falls, and the family is finished! ”

Lao Zhu took a deep breath and felt that his stomach was a little blocked and he couldn't eat...... He prides himself on working hard, but after all, manpower is limited, and there is always something that cannot be taken care of.

Moreover, as an agricultural society, no matter how much you toss, it is three years of abundance and three years of famine, and there are really not many things that can be accumulated. It is completely reasonable that ordinary people are living in difficulty.

Being able to do it without starving to death is already a peaceful and prosperous world.

"Liu Chun, you mentioned the water Gu disease, many of my subordinates also died of this disease back then, some people say that this is the evil ghosts in the water to harm people, but is there such a thing?"

Liu Chun smiled and shook his head, "I don't know, but I know the origin of the water Gu. ”

"Oh? How did it come about? ”

"Quite simply, it's a parasite that is found in aquatic organisms like snails...... People often go into the water, they will come into contact with it, and this insect will enter the human body, live in the intestinal blood vessels, and suck blood. As a result, the abdomen will be swollen, and the person will become emaciated and even die. ”

Lao Zhu was quite surprised, this was the first time he had heard this kind of speech.

The ancient Chinese liked to use "qi" to explain everything, they believed that the poisonous gas in the water condensed and entered the human body, making the abdomen gradually enlarge, so it was called Shui Gu!

Suffering from water Gu, some people will die quickly, and there are many more people, although they do not die, but they have a big belly, their bodies are emaciated, they can't work, and they become a burden to the family.

Zhu Yuanzhang still remembered that among his brothers, some people were infected with water Gu and died a very miserable death.

"Liu Chun, how do you know that what you say is true?" Lao Zhu said very seriously.

"This ...... Naturally, it was taught by the minister's teacher, but the minister verified it in Changsha and found that it was indeed true, and according to the minister's method, the water Gu disease was reduced! ”

"Really less?" Lao Zhu asked with surprise.

"Well, that's right."

Water Gu disease is indeed a trouble, Jinling is by the river, every year the water division of the imperial court, the surrounding people, and even some officials will be infected with water Gu disease. Once sick, even the most brilliant imperial doctor is helpless.

Zhu Yuanzhang still remembered that before the Battle of Poyang Lake, thousands of sailors all suffered from water Gu disease, and they were almost defeated by Chen Youliang.

"First of all, we must identify the cause, which is a disease caused by very small parasites, after a person is infected, the worms will lay eggs in his body, and with the feces are excreted outside the body, these eggs need to grow and develop in the body of the snail, and then parasitize the human body again when they grow up."

The principle of schistosomiasis is not complicated, but people have not understood it for thousands of years, so they suffer from the disease. In some serious water towns, more than two or three percent of the people are infected, and even in some villages, more than ninety percent of the people are infected with schistosomiasis.

Taking the current Ming Dynasty as an example, there are millions of infected people, and along the Yangtze River, almost all patients suffering from schistosomiasis can be found.

"I don't have a cure for this disease, so I can only start with prevention, and the most important thing is to eliminate snails...... We've made a lot of efforts. ”

Liu Chun's so-called us naturally refers to the people who went to Changsha with him. They originally planned to reform the tax system, but the problem was that they found that they could not get the local people to accept them, and there were many misunderstandings between the two sides. Faced with a predicament, Liu Chun decided to open the impasse with schistosomiasis, which all the people cared about.

He used the land rent of the Tan Wangfu as a reward to collect snails from the people.

Then, he put in the effort to overhaul the toilet...... That's right, it's what Modi did the old immortal.

The patient's feces are treated, composted intensively, and fermented.

It's hard to imagine how a group of students can do such a thing? It's just sven sweeping!

But Liu Chun did it, and the result was that the number of new schistosomiasis infections in Changsha Mansion dropped greatly, by as much as 50%!

The common people saw the effect, and almost all of a sudden, Liu Chun and those students were regarded as living bodhisattvas who rescued the suffering, and they had to survey the terrain and clear the acres of fields, all of which went smoothly...... No, it is possible for Liu Chun to give Lao Zhu a complete topographic sand table within half a year.

The data he recorded above is absolutely accurate, because no ordinary people are willing to deceive them!

"I see!"

Lao Zhu finally suddenly realized!

No wonder Liu Chun can do things that others don't do, it looks beautiful, and the hardships behind it, only he knows that a group of students who have almost stepped into the threshold of scholars with one foot actually want to help the people repair toilets and dispose of feces!

"Liu Chun, Liu Chun, how can you give it up?" Lao Zhu roared and asked.

Liu Chun was speechless, Lao Zhu, you still have the face to ask me!

"Your Majesty, when the big guy started, he didn't want to. The minister told them that you are protégés of the Son of Heaven and cannot disappoint the master...... Therefore, they are obedient, and this is also the way His Majesty taught! ”
