Datang: The prince of salted fish was overheard by Li Er

Then Li You continued to play: "At that time, the cement road will be repaired, and I will get a luxurious four-wheeled carriage, which will be much more comfortable to keep than the current two-wheeled carriage."

In fact, Li You also knew how huge the project of transforming all the roads in Datang into concrete roads was, but after he said it, he felt that this matter was a new direction of his efforts.

After completing several major events that caused his kindness points to skyrocket, Li You also clearly understood that the points generated by small favors and small benefits can basically be ignored in the face of the massive amount of points needed for the system upgrade time.

Only by completing such a major event related to the people's livelihood can the upgrade time be significantly changed.

In Li You's view, apart from foreign wars, what is closely related to the people is nothing more than basic necessities of life.

Now the construction of garment workshops has begun, and new food crops are also being promoted.

It will be sooner or later that the appearance of red bricks and cement will improve the housing quality of the common people in Datang.

So the remaining major breakthrough is the travel of the people.

In ancient times, traveling far has always been a problem.

At the heart of the problem is the difficulty of walking.

Originally, when Li You and Sakura talked about the road construction, they just changed the subject, but after they really said it, Li You paid more attention to it.

Li You closed his eyes and began to think about where his road construction plan should start.

Starting from the capital city, it is currently the busiest official road from Chang'an to Luoyang, or there are other options.

The matter of road construction is much more complicated than his previous workshops. From the beginning of the design, it involves all kinds of problems, so Li You has to be cautious.

Seeing that Li You was deep in thought, Sakura also obediently closed her mouth, silently added some fuel to the bonfire, sat aside, and stared at the master she was going to serve her whole life.

This time, Li You's thinking didn't last too long. It wasn't that Li You quickly thought of a solution, but that he moved this process into the system space.

In the system space, not only is the time unlimited, but Li You can also get the assistance of many materials.

The help that the graphic video room can provide Li You is not as simple as books, there are also a lot of video materials, including some expert explanations.

By the time Li You exited the system space, he already had a bold plan.

[This time labor and capital not only need to build roads, but also let these aristocratic families pay for it. 】

[Not only do they have to pay for it, but they also have to beg for wages to repair it. 】

After the plan in his mind was roughly completed, Li You remembered that he seemed to be talking to Sakura.

But when he looked back at Sakura, he found that Sakura had fallen asleep with her head propped up.

After a night of nothing, after dawn the next day, a group of people came to the first village on the road to live.

Obviously, this was not the first time for Sun Simiao to come here. As soon as the group entered the village, they were enthusiastically surrounded by the villagers.

"The old god is here to help us heal again!"

"Thank you, old fairy, if it wasn't for you last time, my kid would be gone!"

"The old fairy is here again, this time, you should always stay at my house!"

"Old Immortal..."

Facing the enthusiastic villagers, Sun Simiao also looked energetic, and looked back at Li You from time to time.

That look seemed to say: "Boy, have you seen it? Although your grandpa grandpa's medical skills may not be as good as yours, he still has a solid foundation in the masses."

Next, Sun Simiao ignored the enthusiastic invitation of the villagers, and immediately began to see the villagers in the ancestral hall of the village.

Originally, Sun Simiao wanted to use this visit to improve his glorious image in Li You's mind, but unexpectedly, after seeing the third patient, his face showed embarrassment.

"Master Sun, what is my disease?"

The patient was a peasant woman, and there was a thin teenager in his teens with him.

Sun Simiao pondered for a moment, then let the peasant woman and children rest for a while, while he himself was the kind of Li You who entered the inner hall.

"You'er, what can you tell about this peasant woman's illness?"

This time when Li You went out in micro-clothes, several people also changed their names.

At this time Li You also frowned.

To be honest, when the peasant woman just walked in, Li You didn't feel anything wrong, and thought it was just an ordinary pregnant woman.

However, at this time Li You heard a few gossips.

"This Widow Xue still has the face to come and see a doctor!"

"His husband has been dead for so many years. I don't know which wild man he hooked up with, and he has another evil seed."

"On weekdays, she still pretends to be arrogant, saying that she is sick, with such a big belly, what else can she be except pregnancy!"

After hearing a few words, Li You quickly took another careful look at the peasant woman.

At this glance, Li You saw the problem.

This peasant woman has a dull complexion, yellow skin and sclera, and black moles on her face and neck.

Around these moles, there are visible small blood vessel branches, which are often referred to as spider naevi.

Based on such a sign, combined with her swollen stomach, Li You had already made a judgment in her heart.

Now being asked by Sun Simiao, Li You said, "I think the patient must have a liver problem. As for what kind of problem it is, I can't confirm it just by observation."

Sun Simiao nodded: "It's very rare for You'er to see so much just by observing."

"Judging from the woman's illness, the old man estimates that it is probably a water gu!"

Hearing that Sun Simiao said it was a water Gu, Li You hadn't reacted yet, but the people beside him cried out in surprise.

Taking advantage of this gap, Li You also immediately entered the system space to search for this inexplicable-sounding name.

Soon, the system space gave him the answer he wanted.

The record about water gu is not far from the Tang Dynasty. It comes from the book "On the Origin and Symptoms of Various Diseases" written by Chao Yuanfang, a medical scientist in the Sui Dynasty.

The poisonous gas of water gathers inside, causing the abdomen to grow bigger, shake and make noises, often want to drink water, and the skin is thick and black, as if swollen, which is called water gu.

The situation recorded in it is also consistent with that of the peasant woman.

However, after knowing what kind of disease it was, Li You had the same difficulty as Sun Simiao.

This disease is already very rare in the modern age where Li You lived, and it also has a name called schistosomiasis.

Schistosomiasis, also known as "big belly disease", is an infectious disease caused by schistosomiasis parasitic in the venous system of the human body.

It is mainly transmitted through snails in ditches and rivers, and eggs in the feces of patients and sick livestock hatching into the water. It is very harmful and wide-ranging, which is really rare.

Before [-], schistosomiasis, like a black ghost, spread wildly in the vast countryside of the Yangtze River Basin and more than a dozen provinces to the south, resulting in deserted fields, no human habitation, and overgrown withered weeds.

However, with the strong support of the state, this extremely harmful disease has been effectively controlled through environmental governance.

In the information just now, Li You has already found a specific plan for preventing and treating schistosomiasis.

But for the patients in front of them, these plans are not a solution at all.
