After a pause, Nian Ruyi made another example, "A thread, half broken, is used to use the reinforcing cream, and that thread can grow well, but if the thread is broken and one thread becomes two threads, it is useless even if it is used to use the reinforcing cream."

"So, you can't heal your broken leg?" The emperor said a little disappointed. If the Nanxing Kingdom could produce a miracle doctor who could cure all the broken leg, then the Nanxing Kingdom would not worry about not being strong and enriching the people.

Nian Ruyi smiled slightly and said, "It's not impossible to treat it. If I could tie that thread up again, my legs could still walk. But, Master, think about it, if there is an extra knot in the middle of the thread, it will become shorter. At that time, this walking will be..."

"If both legs are broken, will you walk as usual?"

"No, Master, I'm not a god, how can I tie two identical knots? Besides, if there are two broken left leg and three broken right leg, it will still be inconsistent."

Despite this, the emperor was still very happy, "So, you will still get a broken leg. This is great, Ruyi, it just happened that the prince of the Nanwang Mansion had two legs broken. Why don't you try it and see how it was connected?"

"Criminal of the Southern King?" Nian Ruyi's face was confused, as if she had never heard of this. "The emperor asked Ruyi to come today to pick up the prince of the Southern King?"

The emperor said with a headache, "Early in the morning, Prince Nan came to me and cried. I was so angry that I was so excited. I just went to the Nanwang Mansion. Afterwards, no matter how the Prince Nan was treated, I would be rewarded."

"I want to heal the Prince of Southern Kings. Why do I have the nerve to ask for the Emperor's benefits? That benefit should be given to the Prince of Southern Kings. I heard that the Prince of Southern Kings has a peerless sword in his hand, so I might as well let him use this sword to exchange for two legs. The emperor sent someone to the Prince of Southern Kings' Mansion to ask. If the Prince of Southern Kings agrees, he will send the sword to him. I immediately take action to pick up his legs. If I don't agree, I will pretend that I have never heard of this."

Upon hearing this, the emperor immediately sent someone to the Nanwang Mansion.

Soon, the people sent came back, and the ones who came back with him were also Prince Nan.

Prince Nan came with a sword in person, "Mr. Ruyi, this is the sword you want, and I will hand it over to you."

Nian Ruyi was very happy when she got the sword, but said, "Prince Nan, I will take the lead in saying the ugly words to help the prince of Nan pick up his legs, but I don't guarantee that his legs will be as intact as before. You know, this broken leg is not easy to connect. Even if it is better, there will be some problems when walking in the future."

In order to prevent the Nanwang Mansion from causing trouble for her in the future, Nian Ruyi specifically implied that in front of the emperor, the Prince of Nanwang would become a lame man in the future.

In the eyes of Prince Nan, a lame man is no less than a disabled person who has no legs and ten thousand times stronger.

Therefore, Prince Nan's attitude was very good, and he promised that he would not cause trouble for her in the future.

However, to go deep into the enemy's cave, for his own safety, Nian Ruyi also begged the emperor to send two young father-in-law and two nannies to accompany her to the Nanwang Mansion.

But the emperor sent two imperial physicians to accompany her and said with a smile, "It is their honor to be able to learn from the disciples of Yao Lao."
