With Du He's understanding of Jia Yi, Jia Yi would never joke about this kind of thing, and looking at the serious expression on Jia Yi's face, Du He suddenly stood up from the chair, looked at Jia Yi deeply, and turned around and walked out of Du Ruhui's room.

Soon Du Ruhui came back, but Du He didn't come back with him, Du Ruhui, who knew that his second son had a temperament, didn't care much, sat on the edge of the bed and said to Jia Yi: "I used to be slightly fat, and I always felt that everything was inconvenient, but now that I have lost weight, I feel that my actions are also a lot lighter, and I still lose weight." ”

"Uncle Du, although the little nephew doesn't understand medical skills, but he has also heard of your disease, although the little nephew can still be sure, but there is also a certain guess, I call your disease diabetes, I have asked Du He to take your urine, and the little nephew will conduct a simple experiment later, if the experiment proves that you are diabetic, you should be careful."

Jia Yi said seriously, but Du Ruhui was full of inexplicability, although he didn't know any medical skills, but he understood the meaning of this disease for the first time with such a direct name as diabetes, but this urine sugar should not be an ending that is too good to eat, how can it still be regarded as a disease?

"Uncle Du, don't dare to underestimate diabetes, although this disease does not directly kill people, but it can cause many other diseases, and those diseases are all fatal diseases, so you must not be careless."

Regardless of whether what Jia Yi said was true or not, Du Ruhui was very satisfied with Jia Yi's concern for him: "Okay, just rush to this filial piety, and do whatever you say today." ”

Soon Jia Yi used ants to verify whether Du Ruhui's urine contained sugar, just look at the ants who were afraid of water, drop a little urine and climb all over the layer, Jia Yi knew that he guessed that Du Ruhui had diabetes.

Diabetes is still very easy to solve without complications, that is, a reasonable diet, eat less foods with high sugar content, and it happens that I have experience in this area when I served my grandfather before, and it is estimated that it will be impossible for Du Ruhui to eat Haisai like before in the future.

Soon Jia Yi gave a method of meal matching, and cherished it in Du He's hands, and told him very seriously that if he didn't want Du Ruhui to die, he must eat strictly according to the food listed on this list.

Du He nodded heavily and put the list handed over to him by Jia Yi in his arms.

There is a folk remedy that saying that eating more fiber-rich things can effectively treat diabetes, although I don't know if this is true or not, but according to Jia Yi's understanding, fiber-rich foods can make people feel full, but they can't absorb fiber, which is a disguised control diet.

At noon, Du Ruhui was about to rest, Jia Yi hurriedly retreated, and walked out of Du Ruhui's room behind Du He, but when he just walked out of the room, Jia Yi's eyes fell on a small map hanging on the wall.

However, this map is really simple, the landform does not have any marking, the place name marking is not very complete, the most important thing, the place name marked on this map is only some common, many places are even blank, which belongs to the largest area of Tibet.

To say that the map of China is deeply imprinted in Jia Yi's mind, this is nonsense, but he still remembers some key place names very clearly, the most important thing is that Jia Yi knows that the knights in the world walk the north and south of the river, and he knows the geography of the Tang Dynasty most clearly, as long as he can find the last more knights, then he will be able to present the territory of the Tang Dynasty on the map.

It just so happens that there is nothing to do when he is idle now, and drawing a map has become the direction that Jia Yi will work on next.

After coming out of Dufu, Jia Yixin walked on the street, pondering how to attract knights to tell him the name of the place, thinking for a long time, before thinking of Pu Songling's way to write a chat, people set up a small tea stall on the side of the road, and listened to the small merchants and vendors from the south to the north to say some strange stories, and then sorted out into a book, Jia Yi can tell the world, as long as he can fill in a place name he does not know on the map he draws, you can get a silver tael, I believe that there will be a lot of people to come.

Just do it when you think of it, in order to prevent those knights from finding some unknown village names to fill up the numbers, Jia Yi limited the place names to the county at a minimum, and before starting, he was going to find some professionals to write out some common ones in the Tang Dynasty.

Now Jia Yi is like a child, with toys, he is naturally in a better mood, and he wanders slowly in the bustling Chang'an, and both sides of the road are full of small merchants and vendors selling all kinds of high-quality products, including Hu people and Tang people.

When Jia passed by a Hu merchant along the way, he was immediately attracted by the fiery red items on the vendor, which was a plant, red, slender and long, with a thick end and a pointed end, what else could it be if it wasn't a chili pepper.

For the first time, several Sichuan recipes appeared in Jia Yi's mind, such as spicy chicken, spicy hot pot, etc., all of which were full of delicious food.

"How did you sell this thing?"

"Always a pound of money."

Damn, robbery, Jia Yi's eyes widened and he looked at the bearded Hu people squatting behind the stall, and immediately found that these Hu people also had black hearts.

"It's too expensive, cheaper, cheaper, I'll buy it."

"It's not cheap, it's always a pound of money, these things are hard to come by, if they are sold cheaply, our pay is not proportional to the return."

Who taught this Nima, and learned it in proportion, so the culture of the Tang Dynasty can't be hidden and tucked away, so it has to be very generous to make the whole world all over the world, and then let them study and excavate, and finally form knowledge to enrich themselves, strengthen their technology, and finally use these to attack the Tang Dynasty?

"Okay, it's always been consistent, and you'll put it all up for me."

In fact, it turns out that Hu Ren has only learned to be shrewd verbally, as for calling this magical thing, they have not yet learned how to use it, and in the end it is a small sack full of several catties of chili peppers, which was actually regarded as a catty by him, and all of them were stuffed into Jia Yi's hands, and only Jia Yi was always charged.

Jia Yi, who went home with chili peppers, has already begun to calculate how to plant chili peppers, hot pot has been promoted the year before last, but the hot pot at that time due to the lack of chili peppers This magical thing has led to only one kind of clear soup, and now with chili peppers, then the hot pot can also add a spicy hot pot.

As soon as I got home, I heard my son's loud cry, handed the chili pepper in my hand to the housekeeper aunt and asked her to keep it safe, and hurriedly walked in the direction of my son.

As soon as he came to the small courtyard where he lived, half of the smile on Jia's face disappeared, there was no way, a little old man stood in the courtyard, which made Jia Yi happy.

Wei Zheng estimated that he had finished dealing with Wei Shuyu, and his mood had changed a little better, and he was happy to play with Jia Lu at this time.

"The kid has seen Zheng Guogong."

"You're back, what have you been doing for so long, I thought you kept coming back today." Wei Zheng held Jia Lu in his arms and snorted coldly at Jia Yi.

"The kid just walked around casually outside, I didn't know that your old man was coming, otherwise I would have come back early."

"Okay, today's incident is my ignorant son, it's not right, the old man will take him to compensate you."

Wei Zheng is this good, admit his mistakes directly, and never beat around the bush, he is a dignified Zheng Guogong, and he apologized to Jia Yi, a little baron, and said it simply, and he didn't even have any uncomfortable expression on his face.

"You've been tormenting the kid for a long time, and the kid was too serious about it before, and he always caused trouble for you."

As soon as Jia saw that Wei Zheng was soft, he also got off the donkey down the slope and directly revealed the matter.

"Boy, you can make a deal in the army, don't tell the old man, what you did yesterday was really for the good of the farmers in my village, even if you say it, I don't believe it."

Wei Zheng's words are equivalent to seriously doubting Jia Yi's character, although Jia Yi's thoughts are not simple, but the farmers have really benefited from it, which is also an indisputable fact.

"It can only be said to be a win-win situation, and it can't be said that it is good for anyone and bad for whom."

Farmers get chickens and ducks for no reason, and can also lower the eggs produced by chickens and ducks to sell to Jia Yi for money, no matter from what point of view, these farmers are earning, although Jia Yi began to lose some chickens and ducks, but with the continuous expansion of sales of salted duck eggs and tea eggs, his demand will become more and more, although these two kinds of eggs have not yet been listed, but the situation that can be popular in the entire market has been expected by Jia Yi, it is unlikely to make a big profit, but there is no problem at all to make a small profit.

After explaining this win-win situation to Wei Zheng clearly, the first thing he thought of was how Datang should achieve a win-win situation with farmers, it stands to reason that Jia Yi's attempt is very good, but the treasury can't take out so much money at all, and the upfront investment for doing this kind of thing is very large, and it can't be done by saying it.

"Alas, this is also a solution, and I will report it to His Majesty the Emperor in the near future, and ask him to consider it."

Listening to Wei Zheng's meaning, it seems that Li Er gave all of them this kind of order to fill the treasury, it stands to reason that this has just repelled the profits, it is a quiet and peaceful time, the treasury is slowly filled, there is no need to worry, since it is not for war, then he can't use money to give people away?

What Jia Yi didn't know was that in the near future, the hundred countries would not come to the court to give Li Er things, as a big country, Li Er would give them back, but now that the treasury is empty, take chicken feathers as a gift.
