The Ming Dynasty started with caution

The Zhou brothers, Duke Ningguo and Earl Changning, had just heard that the Queen Mother was unwell, so they came to visit her late.

The Queen Mother did not like the two of them to come to the palace often: "I am in good health. The prescription of the Yan family is useful. I don't feel so much pain after using it. Don't worry."

Zhou Yu's eyes turned: "Sister, are you talking about the prescription of the Earl of Anding?"

The Queen Mother seemed to know what he was thinking: "Don't have any crooked ideas. The emperor has ordered the prescription to be announced to the world."

Zhou Yu was sullen, and no one knew what he was thinking. But Duke Ningguo Zhou Shou and his sister started chatting about family matters, and they forgot the time while talking.

Zhou Shou and Zhou Yu held hands and came out of Renshou Palace. Zhou Yu suddenly covered his stomach: "Brother, I have a stomachache. I need to find a side hall to relieve myself. You go back first."

Zhou Shou did not say much. This younger brother was always abnormal like the Zhang brothers.

Yan Mansion,

After finishing his duty in the evening, Yan Chengjin returned to the mansion and saw a familiar figure, Changning Earl Zhou Yu, wandering in front of the mansion with his hands folded.

Seeing him, Zhou Yu showed a cunning look and walked up to him cordially: "My dear nephew, I have an urgent matter. I heard that you have a recipe for winter melon frost?"

Yan Chengjin's face was covered with black lines: "My dear nephew has a mouth ulcer, just go to the imperial physician. I am a civil servant, not a medical officer. Civil servants work in the Hanlin Academy, and medical officers work in the Imperial Hospital."

Zhou Yu looked resentful: "I don't have a mouth ulcer, I just want a prescription."

Zhou Yu followed Yan Chengjin into the mansion: "My dear nephew, you don't know that this new prescription needs medicinal materials. It will take a lot of time to promote it to various departments. I will take the initiative and send this prescription out before the court. Selling it to doctors in various places, wouldn't it be possible to make a lot of money?"

The imperial power does not extend to the county, and the counties below are all self-governing.

The imperial decree was probably not as fast as the trade when it reached the various departments, especially in the areas governed by the chieftains in the south, where they resisted the imperial decree, and merchants were more likely to be accepted.

In the Ming Dynasty, you could still make a lot of money by taking advantage of the information gap.

It is easy to get involved in gossip when you have dealings with relatives.

Yan Chengjin didn't want to pay attention to him: "The prescription is in the Imperial Medical Office, just go get it, sir."

Zhou Yu stared: "That Liu Yongyi? When he came to see me, he said that I was dying and asked someone to take care of my funeral. I scolded him as a dog-skin plaster doctor and said that I would never have any dealings with him. I would not go even if I had to lick a dog."

He is quite courageous.

If Zhou Yu could promote winter melon frost to the departments as soon as possible, it would be a blessing for the people.

Yan Chengjin entered the main hall to prepare for dinner, and Zhou Yu followed him in. It seemed that he wanted to eat a meal of running chicken and sat down at the table.

Unexpectedly, at this moment, there was a clang outside the door, followed by a delicate cry of pain.

Zhou Yu was startled and shouted, "Who ruined my dish!"

Qian Jin was even more at a loss after being frightened by Zhou Yu. She cut her hand while picking up the broken porcelain pieces and was afraid of being scolded: "Master, deduct it from my wages."

Yan Chengjin said with a stern face: "Stretch out your hand!"

Qian Jin lowered her head and stretched out her hand in fear, thinking that she would be scolded and dared not look at Yan Chengjin.

Yan Chengjin took out a bottle of medicine from his arms and poured it on her wound, and the bleeding stopped quickly.

Yan Chengjin had lived in the countryside. There are many ways to stop bleeding in the countryside, including spitting on the wound, sprinkling soil on the wound, applying puffballs, and spreading boy urine...

He often practiced archery in the yard. Even though he was as steady as Lao Gou, he still prepared trauma medicine for use.

The main ingredients of this medicine are Panax notoginseng, Aconitum kusnezoffii and puffballs.

The goal is to make a low-end version of Yunnan Baiyao.

Yan Chengjin remembered that Aconitum is one of the ingredients of Yunnan Baiyao.

He Neng tried it many times, and the wound of normal size was sealed when bleeding.

Looking at the wound on Qianjin's hand, Yan Chengjin secretly remembered in his heart, the 101st test, test subject: female, wound length: about two centimeters, effect: can stop bleeding, no abnormality found.

Qianjin's eyes moved, gratefully said: "Thank you, young master."

Zhou Yu looked at the bottle of medicine in Yan Chengjin's hand, his eyes were about to pop out.

If this medicine is sent to the front line, wouldn't he be rich?

I heard that there is a war in Yunnan, Guizhou and Milu now.

"My dear nephew, what kind of medicine is this? Can you lend it to me to have a look?"

Yan Chengjin glanced at Zhou Yu again: "Before my father left, he specifically told me that if anyone dared to take the secret recipe of the family, he would break his three legs first, and then tell His Majesty, so that His Majesty can judge justice."

Zhou Yu's head shrank: "Oh, nephew, where did it go? I just wanted to borrow it to have a look."

"My Lord is not sick, it's useless to look at it."

Zhou Yu hit the doorpost hard and bled: "Oh, why didn't I see this pillar just now? It's bleeding, haha, nephew, I'm going to die, give me some medicine quickly."

Yan Chengjin was confused: "Changning Bo... Is there something wrong with your brain?"

People are bleeding, and suddenly they feel that this is not good.

Zhou Yu smiled and said: "Hurry up and apply medicine to me, I... seem to be a little drunk."

Yan Chengjin pulled out the cork and was about to pour the medicine.

Zhou Yu called out urgently: "Don't pour it on the wound."

"???" Yan Chengjin.

"If you don't pour the medicine on the wound, where should you pour it?"

"Just pour it on my palm."

Yan Chengjin poured the medicine on his palm. Seeing that he had lost so much blood, he poured more for him. In the blink of an eye, the whole bottle was finished.

Zhou Yu was angry. Why didn't you give me the bottle earlier?

But he was happy again in a blink of an eye. The powerful doctors in the capital can tell the ingredients of the medicine after tasting it. When the time comes, he will sell this medicine to the military households and earn a lot of money.

Yan Chengjin did not dare to keep him: "My Lord, remember to see the doctor."

"What about the winter melon frost recipe?"

"I wrote down the winter melon frost recipe in Renshou Palace and asked the eunuch in Renshou Palace to read it three times until he memorized it. Then I went to the Imperial Medical Hall to get the medicine. If you want to know, just go to Renshou Palace to find the eunuch."

The next morning,

the morning light was shining, and the Forbidden City was like a palace emitting glory. The shadow of the sundial was slowly turning towards the hour of Chen. In front of the palace gate, the guards who had been guarding for most of the night yawned.

The dismounting monument in front of the Meridian Gate, four sedan chair bearers carried the sedan chair and stopped here. When the guards saw the shabby sedan chair, they knew it was Yan Chengjin, the Imperial Academy lecturer.

As soon as he got off the sedan chair, Yan Chengjin saw Li Dongyang's sedan bearers walking quickly towards the Meridian Gate not far away, so he waited for him.

"Good morning, Lord Li."

Li Dongyang looked normal: "Before dawn, His Majesty summoned the Earl of Changning to the palace. After hearing that Zhou Yu went to your house, he beat up the eunuchs in Kunning Palace and broke his head. It has nothing to do with you, right?"

Yan Chengjin's face froze. Maybe it had something to do with it.
