"Big brother! I know what is bothering you the most right now? I'm sure I want my Liuyi to form an alliance with you Dafu, so that our brothers can see each other often, so I'll definitely argue with my father in front of him. Tuoba said earnestly.

Yang Yun didn't expect that Tuoba Du actually knew about their troubles and offered to help, which made him overjoyed.

"Thank you, second brother, you are really my lucky star, if you can help me complete this matter, it will be really a blessing for the people of my two countries." Rao is Yang Yun has a calm personality, and he can't help but smile happily.

"But big brother, don't be too happy! Our sons can't influence our father's opinion, and in his eyes, we will always be children who will never grow up. If you want to make this happen, there is another person, if you get her help, then the possibility of success is very high, and that is my imperial grandmother, my father has always listened to her since childhood. Tuoba said.

"What, the thirteen princes of Fuguo have studied medicine with famous teachers since he was a child, and he can treat the old lady's eye disease?" Khan King Tuoba Ye listened to Tuoba Du's report and couldn't believe it. He is a filial son, and his mother has loved her the most since she was a child, so when he became an adult, he was very filial to his mother even when he became the king of Khan.

King Khan's mother, Empress Dowager Xuanyuan, suffered from an eye disease a few years ago, and invited many famous doctors to treat it without any effect, and now it is getting worse and worse.

Listening to Tuoba Du talk about the symptoms of his imperial grandmother, Yang Yun can be sure that the Empress Dowager Liuyi has cataracts, which are very common among the elderly, and if cataracts are not treated in time, they will lead to permanent blindness once they cause other complications. And Tuobada's imperial grandmother, Empress Dowager Xuanyuan, has reached a very serious point and is on the verge of blindness.

This cataract was an extremely difficult disease to treat in ancient times, but it was not a difficult thing for Yang Yun, who concentrated on Western medicine, although the medical conditions in this era were a little poor, but Yang Yun also had the confidence to treat it. So he applied to the King Khan to treat the eye disease of the Empress Dowager Xuanyuan.

Originally, the credibility of a teenager who was just fifteen years old was very low. But the last time Khan King Tuoba Ye met Yang Yun, he had a very good impression of him, and felt that this young man had a calmness and maturity far beyond his age, and he should not talk nonsense.

"Father, I have been in contact with these thirteen princes a few times, he shouldn't talk nonsense, besides, let him come and take a look, if he can cure it, it will have no effect if he can't be cured." Tuoba said to his father.

"I can't see with this eye, it's worse than death, my wife is over seventy years old this year, I am willing to give it a try if I have the opportunity, even if I fail, there is nothing to die, and I can live enough." Empress Dowager Xuanyuan saw it more thoroughly, and her words helped King Khan make up his mind.

"Okay, you go and tell the prince of Fuguo, let him get ready, and let him go to the palace tomorrow to show the queen mother." The Khan pondered for a moment and said to one of his attendants behind him.

Yang Yun finally entered the palace as he wished, and saw the Liuyi Empress Dowager Xuanyuan, a graceful and luxurious, but very kind old man.

"Come on, you can help me see, there is a way to treat it, don't be nervous, even if it can't be cured, no one will blame you." The old lady looked at Yang Yun and said with a smile.

After careful examination, Yang Yun determined that the old man was indeed suffering from cataracts, and he raised his head and said to the old man: "I can treat this, but I need surgery." ”

"Surgery, what is surgery?" The Khan asked in amazement, and when he heard that the cataract in the old man's eyes was to be removed with a knife, the Khan hesitated. There were even princes and princesses who accused on the spot, saying that Yang Yun was trying to murder the old man, and only the fourth prince Tuoba Du was fighting for Yang Yun.

"Alright, alright! Don't fight, I believe that this kid will be blind if he doesn't heal me, and I'm willing to gamble. "The Empress Dowager Xuanyuan finally finalized the matter.

In this era, it is a very troublesome thing to do an operation, and the equipment is not a problem, Yang Yun drew the drawings as early as when he was in Dafu, and asked Tie Feng to create a set of surgical equipment for himself. The problem of anesthesia is also well solved. There is an incense in the palace of Liuyi that can make the old man fall into a deep sleep, which can fully support the completion of such a minor operation.

The most troublesome is the problem of disinfection, which can only be smoked with vinegar and sterilized at high temperatures. The last anti-inflammatory problem, according to the existing conditions, Yang Yun took the method of taking anti-inflammatory Chinese medicine to solve it, although the effect is not very good, but there is no better way at present.

As for the operation itself, it is not too big a problem, Yang Yun was a well-known surgeon in his previous life, and he has done countless such surgeries, so it can be said that he is familiar with it. It took a day to make all the preparations, and Yang Yun successfully completed the operation.

The Empress Dowager Xuanyuan, who had been asleep for several hours, woke up from her sleep and had no other adverse reactions except for some pain in her eyes. The next step is to wait for the gauze to be removed and the effect of the treatment to be tested.

According to the request of the King of Khan, Yang Yun has been staying in the palace for the past few days. According to King Khan, it is convenient to take care of the Empress Dowager Xuanyuan nearby. But Yang Yun understands that he doesn't want him to run away, if there is any accident, I'm afraid he won't even be able to save his life!

Three days have finally passed, and it is time to untie the gauze on the eyes of the Empress Dowager Xuanyuan. The princes and princesses in the palace, as well as some ministers who had received the news, came to the bed of the Empress Dowager Xuanyuan early. They were eager to see if the strange treatment of the prince of Fu Guo really worked.

"Close all the doors and windows, pull down all the curtains, and don't light the lights. After growing up, this eye was wrapped for a few days, and it took a process of adaptation, and too strong light would damage her old man's eyes. Yang Yun arranged all this in an orderly manner, he had done this kind of minor surgery countless times, but this time he felt a little nervous.

Under the watchful gaze of several pairs of nervous eyes, a maid gently untied the black cloth from the old lady's eyes. The old man slowly opened his eyes and slowly looked at everything around him.

"I see, I see!" After a long while, the old man suddenly cried out. At this moment, the entire dormitory was happy. One by one, they happily came to the old man to see if he could see himself clearly.

The prince of Fuguo really cured the eye disease that the Empress Dowager Xuanyuan had not cured for many years, allowing her to see again. The news quickly spread inside and outside the palace, and Yang Yun's popularity quickly increased in Liuyi.

"Your Royal Highness, you told the king yesterday that you can still use your surgery to turn eyelids like mine into charming double eyelids like Sister Xiangfei, is this true?" The operation was successful, and Yang Yun was bidding farewell to the Khan King and preparing to leave the palace, when one of the Khan's concubines suddenly came in and asked Yang Yun.

"Of course it's true! It's not a complicated surgery. Yang Yun replied. Double eyelid surgery, also known as blepharoplasty, is one of the most common procedures in plastic and cosmetic surgery. For Yang Yun, this is another very easy little operation.

"That'...... Then can you make me also become the beautiful two-layer eyelids of Sister Xiangfei? The princess was a little hesitant and a little expectant.

"As long as His Majesty the Khan agrees, I have no problem." Yang Yun said lightly.

In the end, the king of Khan did not resist the princess who pursued beauty, and two days later, Yang Yun came to the palace again and performed this "double eyelid plasty" on the princess. ”

The operation was very successful, but it caused problems for Yang Yun. No matter what era a woman is, the pursuit of beauty is always very much expected. Seeing that this princess had become beautiful, some concubines and princesses in the palace, and even the wives and concubines of some ministers in the court, came to beg Yang Yun to turn them into double eyelids. So much so that for nearly 20 days after that, Yang Yun was doing these eyelids almost every day.
