It's good to exchange marriages. My sister eats coarse food while I wear gold and silver.

The emperor, who had been expressionless at first, smiled with satisfaction when he heard Mu Qing's words: "Do you know how many people are trying their best to do things for me? Moreover, I can promise you that after the matter is completed, I will order you to marry Lu Sui."

Mu Qing raised his head and looked at the emperor with disbelief.

"Why don't you believe what I said?"

Mu Qing hurriedly shook her head: "It's not that I don't believe it, but I shoulder the future of the Mu family, and I absolutely cannot be a concubine."

The emperor snorted and laughed: "Then find a way to gain Lu Sui's favor and make him want you. Then he will divorce Yuan Buwei for you and marry you as his legal wife."

"But……"

Seeing Mu Qing's hesitation, the emperor said, "Mu Qing, you said that you are the one who shoulders the future of the Mu family, so you must not hesitate. You must have perseverance and be ruthless."

Mu Qing stared at the emperor in a daze.

"I don't want anyone else to know about this. If you understand what I'm saying, please kneel down and pay your respects."

Mu Qing quickly came back to his senses and kowtowed: "Thank you for your grace, sir. I will take my leave."

It was not until he walked out of Yanying Palace that Mu Qing realized that his back was already soaked with sweat and he was staggering when he walked.

"Qing'er."

The moment she saw her granddaughter coming out, Old Lady Mu hurried over and looked at her with a worried look on her face: "What did the emperor say to you?"

Facing his grandmother's concerned eyes, Mu Qing recalled the gloomy face of the emperor when he warned her: "He just asked me some questions about the Swift Wind Camp. Because it involves the internal affairs of the Swift Wind Camp, the emperor asked grandma to leave."

"Then why do you look so pale?"

"Grandmother, this is the first time I faced the emperor alone. When he asked me questions, my mind went blank." Being able to return to the Gale Camp would also put Mu Qing's mind at ease. As for the things the emperor told him to do.

She can do it.

After Eunuch Liu was sure that the two had gone far away, he turned back to the palace and said, "Your Majesty, they have left."

"Ah."

The emperor placed the four formation diagrams he had obtained earlier on the table together, and then placed the ones given by Old Lady Mu together.

Then he stopped talking.

Seeing the emperor's thoughtful expression, Eunuch Liu took a look and said, "Your Majesty, you were still worried about the fifth formation diagram a while ago. Look, it's here today. The remaining five will surely be gathered in the blink of an eye."

Hearing this, the emperor smiled and said, "That's right, this matter cannot be rushed."

"Your Majesty, you haven't dined with the Empress Dowager for a long time. Some fresh seafood has arrived in the imperial kitchen today. Would you like some..." Eunuch Liu hurriedly brought it up while the Emperor was in a good mood, so as to avoid being blamed by the Empress Dowager when he saw her.

"Well, I haven't seen my mother for a long time, so I'll go to Shoukang Palace."

In Changle Palace.

The third princess, Nangong Fu, the daughter of the imperial concubine, came hurriedly.

"Your Highness has met the Third Princess."

"You are the junior sister that mother often mentions. It was mother who taught me all my medical skills. Should I call you aunt-in-law?"

"You can call me whatever you want, Princess Three. It's always me who is taking advantage of you."

In the previous life, because of the imperial concubine, Yuan Buwei had close contacts with the third princess. Later, she simply followed me to learn medical skills. Every time, she would follow me and call me "Master Aunt", which was very cute.

"Oh, mother, I brought Aunt Jinghe's medical records, but they are not original. I copied them secretly when no one was paying attention, so I guess there will be mistakes."

"Why did you think of copying medical records?" The imperial concubine was a little curious.

"Aunt Jinghe has always been in good health. Even when she suddenly became seriously ill, the Imperial Hospital used all the good medicines, but not only did she not get better, but her condition became worse. I felt something was wrong, so I secretly copied the medical records, but combined with each consultation and prescription, I couldn't figure out what was going on."

"Let me see."

Yuan Buwei took the medical record, walked to the desk and read it carefully. After a moment, she found out: "It's a problem with the prescription."

"prescription?"

The lady and her daughter came over, took a look, and were very confused: "The symptoms described are consistent with the prescription, what's the problem?"

"All medicines are poisonous. Although the prescription is correct, you can see that every time the medicine is prescribed, the dosage of some of the medicines in the prescription will be adjusted. Although the dosage adjustment is not much, Princess Jinghe has been taking medicine every day since she fell ill three years ago. The toxins will accumulate in her body. Moreover, the vessels for boiling medicine, the bowls for holding medicine, and the meals she eats three times a day are all non-toxic when verified separately, but what about when they are combined together?"

The mother and daughter's faces turned pale instantly.

"To be able to arrange it so meticulously..." The imperial concubine suddenly stopped talking.

"Mother, why are you silent? Are you feeling unwell?"

The imperial concubine shook her head and glanced at Yuan Buwei.

No wonder she told me that she came here today for Princess Jinghe.

As the emperor's favorite concubine, she had heard a little about what happened between the emperor and Princess Jinghe, but she never expected...

"Bu Wei, have you thought about this matter carefully?"

Everyone kept their mouths shut. Apart from the emperor's order, who else would have such great power?

Yuan Buwei nodded: "Senior Sister Wei, I have already thought about it, so I decided to come to the palace to find you, and now that I have the medical records, I want to see Princess Jinghe in person!"

Although Nangong Fu didn't know the whole story, one was her mother and the other was her master's aunt.

As a junior, there is no reason for me not to help.

"Mother, you can let Master Aunt pretend to be my maid. As a niece who knows medicine, it is normal for me to visit my aunt." Nangong Fu looked at Yuan Buwei and said, "Everyone always says that Aunt Jinghe's style of doing things is high-profile and flamboyant, and she doesn't have the dignity of a royal princess at all, but I just like Aunt Jinghe. Unfortunately, I am not well-educated and can't even understand the medical records."

"Don't say that, Third Princess. You have only been exposed to medical skills for a few years, but I have been trained by my master and uncles since I was a child. I spend at least ten of the twelve hours a day dealing with medical skills. In Medicine King Valley, I have to see many patients every day. As the eldest sister said, it is better to practice than to talk about it on paper. So the reason you feel that you are not strong enough now is because you have not seen enough patients."

Yuan Buwei's words greatly comforted the Third Princess: "Perhaps because of my status as a princess, the Imperial Hospital did not allow me to see patients, and instead asked me to stay in the study and sort out various medical books."

"There are many books in Medicine King Valley. My master asked me to finish reading a book before going to bed no matter how late it is. He will test me the next day, so the third princess can use this opportunity to memorize all the knowledge in the book so that she can apply it flexibly when she encounters it next time."

Nangong Futing's eyes lit up: "Master, I understand."

"Oh no, Madam Imperial Concubine..."

At this time, the palace maid ran in from outside and said, "The emperor is dining with the queen mother. Because the seafood that arrived today is very fresh, the queen mother was greedy and got burned. Now she suddenly has difficulty breathing and her face is purple. You should go and have a look."
