After a few days of recuperation by Lu Ning, the crown princess's condition has turned critical, and she basically can't die in the fourteenth year of Hongwu.

And the emperor's grandson Zhu Xiongying, after his condition stabilized, Lu Ning, as his master, formulated a set of scientific exercise methods for him, called Huatuo Five Fowl Opera.

After all these foundations are laid, there will be very few places where he is needed.

In addition to coming over regularly every day to give lessons to the emperor's eldest grandson for two hours, the rest of the time can be made in the mansion to make some inventions.

Ever since his reputation as a miracle doctor spread, people have been looking for him to heal his illness.

At first, it was Lan Yu's family, and later Li Shanchang, Li Wenzhong, Chang Mao, Tang and Deng Yu and others took turns to invite, and each visit had a very generous consultation fee.

And these people are all members of the Prince's East Palace, and they have a natural affection for him.

Seeing that the condition of the crown princess and the emperor's eldest grandson was getting better day by day, a stone in the hearts of these people also fell to the ground.

On this morning, just after executing the plan to create a man with Li Xinmin, Lu Ning received a report from Changshi.

"Grandpa, the Yan Mansion has sent an invitation, please go to the palace to treat Princess Xu and the prince."

Speaking of which, Yan Wang Zhu Di is still Lu Ning's brother-in-law, and Yan Wang is married to Xu Miaoyun, but Yan Wang is a brother-in-law, and he is a brother-in-law.

Recently, due to the back and forth adjustment between the two sisters, the estrangement between Lu Ning and Yan Wang has gradually been eliminated.

Since King Yan came to invite, he decided to take his second apprentice Xie Jin with him.

On the way, he whispered to Xie Jin.

"When you arrive at the Yanwang Mansion, there must be a door on your mouth, say what you should say, don't talk nonsense if you shouldn't say it, whether the Holy Sun is good or bad, it has nothing to do with you."

Xie Jin said with an aggrieved face.

"I don't know which emperor you're talking about, how can you talk nonsense? Could it be that the Master will not know the prophet? ”

Lu Ning sneered and said helplessly.

"You listen to me with your ears pricked up, if you don't want to freeze to death in the ice and snow in the future, just shut your stinky mouth tightly for me!"

Xie Jin was still a little unconvinced, and wanted to debate a few words with his master, but was glared at by Lu Ning viciously, and immediately coaxed.

"Every day, you will shake your wit and play smart, this time you can be a little more leisurely for the teacher, don't let you say it, don't say a word, even if it's lucky!"

Xie Jin said directly.

"Master's high style and brightness are really admired by the apprentice, whatever the master says in the future is what it is, I only have to listen, and I will never embarrass you."

When Lu Ning arrived at Yanwang's Mansion, he found that Zhu Di was waiting outside the mansion gate, and when he saw him coming, he immediately stepped forward and greeted him very affectionately.

"Zi'an, you really came, my brother has been waiting for you here for a long time, hurry up and come in."

Lu Ning did not hurry to salute King Yan, but was immediately stopped by King Yan.

"You and I are brothers, so there is no need to talk about these false courtesies, when you go to the fourth brother's house, it's like going to your own home, please go inside."

Listening to him keep saying this, coupled with his father-in-law's arrangement, if he keeps being so cold to him, he will seem to be hypocritical.

Lu Ning got off the donkey and called him the fourth brother.

The two laughed and shook hands. I forgot that I almost got into tension not long ago.

After entering the mansion and sitting down, Lu Ning said.

"I don't know what illness the fourth sister-in-law has committed, have you asked for a doctor?"

Zhu Di smiled bitterly and replied helplessly.

"Your fourth sister-in-law has suffered a lot with me over the years, and her body has fallen ill, and she has long wanted to look for her brother, but she used to use other imperial doctors' medicine, so she could only stop taking medicine and recuperate for a few days before coming to her brother."

Lu Ning didn't dwell on this issue, and asked directly.

"Can you show me the pulse of the other doctors?"

Zhu Di laughed and said.

"I know that my brother has other attainments in medicine, and the prescriptions prescribed by other doctors are not only not beneficial to you, but harmful to you, so call your fourth sister-in-law out later, and you can diagnose him personally."

Lu Ning said.

"Fourth brother, there is a difference between men and women, is this appropriate? After all, this is not quite in line with the etiquette system and the laws of the imperial court. ”

Zhu Di didn't have so much to do, so he directly gave him a reassuring pill and said.

"You and my brother are good at all, and it is not hindered for the family to meet each other, come here, please come over with the princess, mother and son."

Princess Yan Xu Miaoyun looks six or seven points similar to Xu Miaojin, but there is some decisive momentum between her eyebrows, and she is also a woman who does not let her eyebrows go.

Lu Ning hurriedly stood up and saluted Xu Miaoyun.

"Little brother Lu Ning, meet sister-in-law Wang."

Xu Miaoyun bowed slightly and helped him slightly.

"Uncle doesn't have to be polite, please sit down, when you get here, don't be polite, this is my brother's own home."

Lu Ning began his look, smell and ask, Xu Miaoyun was both civil and military, and he was not taboo about secular etiquette, so he directly asked Lu Ning to diagnose his pulse.

After diagnosing it, Lu Ning immediately knew where Xu Miaoyun's symptoms were, so he picked up a pen and brushed a little bit and prescribed a prescription.

"Fourth brother, now some of the medicine supply units of the Domestic Products Division have mixed authenticity and falsehood of the herbs they offer, so you must be careful when picking up the medicines."

When Yan Wang Zhu Di heard this, he was naturally a little surprised.

"Zi'an, the matter is very high, do you have any evidence? If you say that without any evidence, it will be criticized. ”

Lu Ning shook his head and replied.

"Of course, I believe that the fourth brother will not try to make such a small profit, but there are too many people in the management of the Domestic Products Division, and it is inevitable that there will be a few small people who are deceiving them."

Zhu Di's eyebrows were furrowed at that time, obviously he didn't expect this, but Lu Ning's words made him very vigilant.
