After all, the time he came to this world was too short, and he didn't know much about the cultivation methods of martial artists, and when he cultivated, he knew that just opening the tendons would take longer than he thought, and not only that, but there were unexpected surprises.

Xueba's best at learning is naturally learning, for more than ten days, he desperately absorbed knowledge in Huya, but unfortunately Huya, this kid is too short-sighted, most of the brain is filled with water, this is less than half a month, Renault feels that there is not much to learn from him.

Huya's understanding of Da Chu is pitiful, Da Chu has been established for 500 years, and the royal family is surnamed Chu. Great Chu has eight states and seventy-two prefectures, eight armies, and the capital is Luocheng. Basically, that's all Huya knows, at most there is a Chongzhou Daimyo Mansion, which is the hometown of the Tiger Gang. If you ask anything else, you can only name a Dingjun city, and don't continue to ask about the rest of the city, but go back and forth, that's all.

As for who the reigning emperor is, it is the emperor! How many people are in Dachu, a lot! Who has the final say in the court, I don't know!

Forget it, don't ask, I'm tired.

Renault knows, the Tiger King and the Tiger Sister must know more, but these two are too cold, talk little, ask a few times, people don't like to answer him, Renault is also a little arrogant in his heart, buddy is twenty years old, already a senior, looking at the master's exam, put it on the earth, that is also a proper scholar Okay, you are a group of express delivery people, and you dare to give Brother Lei a face, don't ask you.

The Tiger Pack Gang is not only the three of them, but also dozens of people, these people are much easier to talk to.

Well, it's easier to talk, but what they know is not as good as tiger buds, sad.

Renaud had read history, but he never imagined that in a technologically backward world, seeing this art would be so precious. On the earth, even if something new happens in a remote mountain village, the whole world will know the next day, and when it is like here, Renault even asked more than 20 people, but he didn't ask who the emperor was.

The promise he received was strikingly unanimous, that the emperor was the emperor.

It took two days for Renault to finally target a man he thought was more reliable, the quack doctor he thought was quite unreliable.

In Dachu, doctors are called doctors, that is a master, if the medical skills are superb, it is easy to become a nobleman, with the title of the court, that is, a loose official.

Of course, not all officials can be called nobles, and only official positions above the fourth rank are qualified to be called nobles. Nobles and ordinary people are said to be two different creatures, can you believe it?

From this, Renault concluded that this was a fairly hierarchical political system.

"Doctor Du, when the kid set up camp last night, he got some good things, just to honor you. Renault said with a smile on his face and a sackcloth bag. This doctor was invited by the convoy in Huangshakou, surnamed Du Mingsheng, and is good at treating external injuries.

These are all good-sounding, after a few days of contact, Renault has already seen through it, this Dr. Du is good at trauma, and as for the medicine he dispenses, the effect is quite ordinary.

This is also because Renault's vision is too high, a person who uses four-leaf red ginseng to open tendons, where can he look down on an ordinary trauma doctor like Du Sheng.

He didn't fancy Du Sheng's medical skills, but for the medical pedigree in his hand, it was not good, just the hand-painted medicinal herbs and plants could save the old nose. Fortuna has an analysis module, and it is extremely prepared, but after all, it is only data analysis, and when it is used, it is completely different.

Like green and red fruits, red ginseng, after all, there are a few people who take them directly as medicine, and the vast majority of medicines still pay attention to medicinal pharmacology, and the monarchs and ministers complement each other, and the medical skills here are not as good as the ancient Chinese medicine in the eyes of Renault.

It's a pity that an engineering man who studies electronics has the same understanding of traditional Chinese medicine as Huya's understanding of Da Chu.

"Oh? "The medical skills of this Du Yijia are not very good, but the spectrum is quite big, not to mention a hairy boy like Renault, even if he is a steward like the Tiger King, he is like this, and only when he faces the steward of Tian and the leaders of the various gangs, he has a little smile.

Naturally, there are no good things in the bag, ten green and red fruits each, and two three-leaf green ginseng. Qinghongguo didn't mention it, there were a lot of things in it, Renault couldn't look at it, and Doctor Du didn't look at it very much, anyway, he couldn't learn martial arts, and he couldn't use it himself, so it was just a hundred coins to give him.

If you dare to take the road of gold, it is appropriate to earn ten gold coins in one trip. Twenty blue and red coins are only two thousand copper coins, which are equivalent to two silver coins and one-fifth of gold coins.

But the three-leaf green ginseng is different, a good thing, the three-leaf color represents this is a thirty-year-old ginseng. Wild ginseng is a thing that grows more valuable the more years it gets. The Tiger Gang is poor, but the Tiger Girl is a gang of masters, and the medicinal materials used in martial arts are only ten years of wild ginseng, so it costs a gold coin.

Ten years of ginseng, the market price is one gold coin, twenty years of ginseng price doubled, one plant is two gold coins, thirty years of ginseng plus one gold coin. The market price of these two three-leaf green ginseng strains in Renault's hand is six gold coins, which is already half of his income from a trip to Dingjun City.

"Where did you see it?"

"Not far outside the camp last night, when I was relieved, I was right at my feet, so I picked it with my hands. What Renault said was sincere, he felt that if he was in this world for a few more years and had the opportunity to return to Earth, he would be able to act directly.

"This ...... It's too precious. "Doctor Du doesn't feel good about it, it's worth more than six gold, which is a lot of money, and he has a hot hand. Renault is a member of the Tiger Gang, and the hairy boy has no knowledge, but the Tiger King is an understanding person, and the leader of the gang, Tiger Sister, is not short of knowledge.

If you really accept it, people will come back to the door, and it will be ugly. No ...... My heart is itchy, and my hands are even more itchy. Green ginseng is in the hands of a warrior, it can only be used as a tonic for martial arts, it is called martial medicine, but in his hands it is different, he is a doctor, he can use green ginseng as medicine, which can better reflect the value of green ginseng.

Even if his pharmaceutical skills were a little weaker, he was confident that he would turn this green ginseng, which was originally worth six gold, into a medicinal pill worth eight to nine gold.

"Doctor Du, you're welcome, this is what I picked myself. Renault looked at Du Sheng's eyes, and understood what he was afraid of, and sighed in his heart, being a man really has roots. If it's just him, as long as he is willing to take it out, people will dare to grab it.

Now he already knew how high the value of the six gold was. The purchasing power of a copper coin is about the same as one yuan on the earth, one silver is one thousand copper, and one gold is ten silver. Converted, one gold is equivalent to 10,000 copper.

It doesn't seem like much, but this is not the earth, the level of productivity is very low, and the value of coins is relatively high. In many places, bartering is still being used. If you don't take the road of gold, you can save five to eight silver coins at home all year round, then you can do a good job. If you can earn a gold, then you can have a fat year.

Six gold, enough to buy a murderer, and it is still a martial artist.

Traveling to this world, when Renault knew that the God of Wealth had also crossed over with him, he never thought about making money again.

"Lei boy, what do you want to do?" Doctor Du asked vigilantly, is this to apprentice to the teacher? If you are in Huangshakou, this kind of restraint is enough, but for such an apprentice, he is used as half a coolie. Renault is a Tiger man, so naturally he can't be treated like that.

With less than ten gold coins, he wants to buy his ability and beauty, and he will not make such money. Medical skills are the foundation of his life, even if it is a hundred gold, it must be carefully considered.

This is not Dr. Du's boasting, he is stationed in Huangshakou, and he really can't make a lot of money from pharmaceutical treatment, but he goes to Dingjun City once a year, but the real ten gold coins, as long as he survives for ten years, is it difficult to earn a hundred gold?

"I don't want anything else, I want to see the medical pedigree in the hands of Dr. Du. "The people who walk the golden road are very sincere, and Renault doesn't go around in circles.

Doctor Du was about to turn his face when he heard it, and the medical pedigree of each doctor is a secret that cannot be passed on. It's good to say that the part of the illustrated book is not much different from what everyone has in their hands, and the difference is in the number of the illustrated book. The medical spectrum is amazing. On the earth, the medical spectrum consists of two parts, one is the treatment case, and the other is the prescription of the medicine.

Not to mention in Dachu, which is backward in science and technology, even on the earth, prescriptions are the lifeblood of pharmaceutical factories. As for the treatment case, it's not an autobiographical disciple, who will show it to you, I want to learn to read the textbook by myself.

"Don't worry, Doctor Du, I'm not asking for anything else, just for the hand-drawn drawings of medicinal plants. "Renault understands the trick more than Dusheng, so naturally he doesn't think that six gold can buy a prescription. As for the treatment cases, he was not interested in looking at them at all, and he was not ready to become a doctor.

"Oh, it's just a medicinal plant guide, it's not impossible. "Doctor Du knows in his heart, he is just a more famous doctor in Huangshakou, and there is no comparison with the famous doctor in Luodu, the illustrated book in his hand is not said to be a popular product, and it is not much better.

"Exactly. ”

"Okay, those medicinal materials, Du Mou accepted them. "Both parties feel that they have earned it and the deal has been reached.

This old thing, the illustrated book is actually made of animal skin, no wonder the God of Wealth hasn't scanned it in the past few days. As a scholar, Renault's brain is still quite useful, he found that the number of papers in the team is extremely scarce, and he has always thought that Du Yijia's illustrated book is hand-drawn on paper, but he didn't expect it to be animal skin.

This is the difference in science and technology, the level of papermaking in Dachu is backward, ordinary paper is difficult to preserve for a long time, finely ground animal skins can be stored for hundreds of years, and the medical pedigree illustrated book is such an important knowledge inheritance, naturally it will not be painted on paper. Not to mention that water and fire are ruthless, it is carefully preserved, and for more than ten or twenty years, I am afraid that the text on the illustrated book cannot be saved.

Renault was excited and was just about to start the scan, when his body stiffened and he was in trouble.
