The legitimate daughter was reborn, and the emperor’s little Jiaojiao went crazy.

There is a very high Niaoyin Mountain in Huizhou, which receives plenty of sunshine and has moist soil.

There is a very beautiful flower growing on the mountain. Its flowers are large and colorful, and are rarely seen at the foot of the mountain.

Liang Yanbing accidentally discovered that the fruit and shell of the flower could relieve pain, so he took some home to use as medicine. After tinkering with it and adding a few other herbs, he finally created a real pain-relieving medicine.

After taking the medicine, he was just like sleeping. Even if someone cut him, he would not feel it.

Shi Anxia nodded, her eyes lit up, "Yes, this is the medicine my husband is talking about."

Liang Yanbing hesitated for a moment, "But this medicine is neither good nor bad. If used improperly, the person may not wake up. Even I cannot guarantee that I can control it perfectly, Princess, please think twice."

Shi Anxia looked anxiously, "Are you not sure at all?"

She knew in her previous life that Madam Gao was an excellent doctor, but she had never heard that she had such a miraculous medicine. It can be seen that this medicine cannot be used casually.

When Liang Yanbing saw Shi Anxia for the first time, she felt that this girl was more profound than someone her age.

Until then, he felt that she was still a little girl who was worried about gains and losses, and a tender feeling rose in his heart, not wanting to refuse her wishes, "Why don't you give me some more time, Princess, so that I can continue to research and develop, and use the medicine when I am more confident?"

Shi Anxia thought that so many years had passed, and there was no need to rush. As long as A Niang no longer suffered, it would be okay to wait.

Besides, Xiyue and Nanyan are taking good care of A'niang now, so she feels a lot more at ease.

She nodded and agreed, "Then I'll leave it to Madam Anguo." After that, she handed a box on the table to Liang Yanbing, "Whether it succeeds or not, I will remember this favor. It's just a small token of my appreciation, and I hope Madam Anguo will accept it."

Liang Yanbing said hurriedly, "No need. It's just a piece of cake."

Shi Anxia smiled slightly and opened the box herself, "Would you like to take a look first?"

As the wooden box was opened, a book was revealed inside. Madam Anguo's face changed and she exclaimed, "The Secret of the Luotu! How can the princess have the Secret of the Luotu?"

Shi Anxia did not hide it from her, "Master Huang Wanqian has a unique copy at home. He lent it to me to read, and with his consent, I copied a few copies."

In fact, she can recite it by heart after reading it once.

Huang Wanqian himself didn't know that there were such good things in his family, and they were all hidden in the bottom of the box. After Shi Anxia reminded him, Huang Wanqian asked his sons, grandchildren and great-grandchildren to look for them everywhere, and finally found them in the box in the warehouse of the ancestral house.

No one in the Huang family studied medicine, so it was useless. Only by letting more people see this medical book can its true value be realized.

So Shi Anxia said that he had memorized it after reading it once, and asked if he could recite a few more copies. Huang Wanqian agreed without hesitation, "If a few more doctors can understand the contents, wouldn't we be able to save a few more people?"

Shi Anxia explained to Liang Yanbing at this time, "We now have a copy in the Imperial Hospital, which is in the hands of Doctor Shen, the hospital envoy. Tong'an Medical Clinic has one copy, and I have another copy, which is this one. Madam, don't feel bad about it. Good things should be kept in the hands of people who know how to use them, so that they can play a greater role."

Liang Yanbing held the "Secrets of the Luotu" in her hand and couldn't put it down. She flipped through it immediately. While flipping through it, she sighed, "Yes, if I had read this book earlier, I might have saved many more lives."

Shi Anxia agreed with a smile, "It's never too late to be kind and compassionate." She turned to Bei Hui and said, "Go get those sets of medical books as well."

Bei Hui followed her instructions and brought over a few stacks of medical books and placed them on the table. "Mrs. An Guo, please take a look at these books."

Liang Yanbing took a look and saw that there were introductory medical books, some more difficult books, and some complicated books, all arranged in different categories. She was surprised, "What is this?"

Shi Anxia said her original intention, "Have you heard of Yunqi Academy?"

Liang Yanbing smiled and said, "Look at what you said. Yunqi Academy is far ahead of others. Both the civil and military examinations surpass the Imperial College and the Duke's Mansion Academy. Even if I am ignorant, I must know that the princess runs a school, which is unique."

Shi Anxia blushed, thinking that she had found a good opportunity. She got to the point, "I want to open a medical course, and I have invited several doctors from the Imperial Hospital to teach. I wonder if I will be so lucky as to invite Madam Anguo to teach?"

Liang Yanbing was extremely surprised. "Me? Teacher Ren?"

This is something that requires you to be in the spotlight!

When she was in Huizhou before, she could still pretend to be a servant and run around with her husband. Now that she is back in the capital, she is worried about how to live in the future when she is locked up at home.

She remembered that women in the capital used to stay indoors, and the daughters of powerful and aristocratic families were not allowed to show up outside. Has the capital changed now?

Shi Anxia saw her concerns and said, "The emperor is open-minded. The restrictions on women in the capital are not as strict as before. Not long ago, I worked as a teacher in the Imperial Examination Hall, and the emperor was there at that time. It can be seen that the tolerance of the capital is very high now. I wonder if Lord Gao minds..."

"He doesn't mind. He also knows that I'm not good at needlework, and I don't know how to take care of my husband and children... Hey, my sons are all grown up and traveling abroad. I don't need to worry about them." Liang Yanbing gently stroked her belly. "This child is also very well-behaved and never makes a fuss. There is no problem on my side."

The two talked for a long time and had a very pleasant conversation.

When Cen Yuan came back in the evening, Shi Anxia repeated what Liang Yanbing had said.

Unexpectedly, Cen Yuan's expression suddenly changed. "The flowers are large and colorful? The fruits and shells can be used as medicine?"

Shi Anxia didn't understand why her husband was so nervous, so she nodded, "That's what Madam Anguo said."

Cen Yuan said in a deep voice, "Then Niaoyin Mountain must be sealed immediately."

Shi Anxia was even more surprised, "Why?"

Cen Yuan rubbed his brows and asked, "Have you forgotten how Emperor Rongguang died?"

Shi Anxia's expression also changed, "That! That! Longevity cream?"

Cen Yuan nodded, "The longevity cream is made of this damn thing. If it's not handled properly, it will lead to the destruction of the country. Before too many people know about it, seal the mountain and control it."

Shi Anxia's face turned pale. She didn't expect that a casual chat with Mrs. An Guo would lead to the topic of longevity cream.

What is that longevity cream?

It can make people feel ecstatic and indulge in illusory pleasure. Emperor Rongguang ate that thing and lost interest in government affairs. He kept saying that he was going to become a god.

Shi Anxia didn't know whether he could become a god or not. But she saw that when Emperor Rongguang was dying, he was skinny and had many diseases. Occasionally, he would be lucid for a short while, and when he was lucid, he would ask someone to bring him the longevity cream.

Then, after taking the longevity cream, Emperor Rongguang felt that he was good enough again and felt proud and ready to unify the world.

Some ministers in the court were influenced by Emperor Rongguang and also took Fu Shou Gao. Some even took their sons, grandsons, and even women in their families to take it.

Cen Yuan's face was very serious. "I don't know what that flower is called in the North Wing, but it has a name called 'poppy flower'. In the earliest times, it was indeed a good medicine for curing diseases and saving lives. But over time, some people discovered other uses..."
