Ziyuan saw Li Yundong looking at the book in her hand and her face full of questions. She smiled and said: "the Yellow Emperor's Internal Classic is Chinese, which is too exaggerated!

Li Yundong couldn't help asking, "don't you also say that this is a medical book? Why is it the supreme treasure of practice?"

Ruan Hongling, who was on the other side, easily caught another chance and tried to bury him and said, "fool, idiot, haven't you heard the saying that medicine shows the way and medicine carries the way?"

Li Yundong glanced at her: "I haven't heard of it, but I've heard that only women and villains are difficult to support!"

Ruan Hongling shouted angrily, took Ziyuan's arm, pointed to Li Yundong and said angrily, "sister Ziyuan, look at our kind intentions to help him. He also said such words!"

Ziyuan looked at her helplessly and said, "can't you two stop?"

Then Ziyuan explained to Li Yundong in detail: "you must think it's incredible. Why is such a medical skill regarded as the supreme book of Taoism in the practice world?"

Li Yundong nodded.

Ziyuan said, "do you know the origin of our practice school?"

Li Yundong shook his head.

Ziyuan said: "as early as the spring and Autumn period and the Warring States period, Lao Tzu founded Taoism based on the Tao Te Ching. This school spread to the Eastern Han Dynasty, and gradually formed a religion, mainly Zhang Ling, believed in Lao Tzu's Taoism, and then created Taoism. This is the source of Taoist cultivation schools in the world."

Li Yundong suddenly said, "ah, I see. It's the five Dou rice teaching!"

Ziyuan said, "yes, but do you know how Zhang Ling founded Taoism at the beginning and how to make many people believe in him and worship him?"

Li Yundong's heart moved: "practice medicine?"

Ziyuan nodded slightly: "that's right! This is the way to show by medicine and carry the way by medicine! Although there are thousands of cultivation methods, any method can become a fairy and a God when it reaches the extreme, there are only two methods to become a fairy and a god fastest, one is the way of medicine and the other is..."

Li Yundong didn't wait for her to finish. He quickly answered, "the other is Wu Dao!"

Ziyuan looked at Li Yundong with appreciation: "that's right! Medicine carries the Tao, and martial arts defend the Tao! Let the world respect you, fear you, and dare not offend you. If martial arts is not strong, it is absolutely impossible. But let the world love you, believe you, and worship you. Force alone can't do it. Only practicing medicine and charity can do it!"

With Li Yundong's voice, he suddenly felt that the things that the little fox had told him before had suddenly become integrated: "no wonder the little girl said Sun Simiao was an immortal! It turned out that he really entered the Tao with medicine! So sun Lutang became an immortal?"
