"The first realm of the Yin Nine Dharmas is naturally necessary to understand. Even if you enter this first realm, you can become famous in China. If you can practice the third needle, you will definitely be qualified to become a master of national medicine."

"At that time, I studied hard for many years. At the age of ninety, I finally comprehended all the Yin Nine Methods! Therefore, this is the confidence that I can stand out in the world with my medical skills."

Hearing this, Bai Yi couldn't help but be confused and asked, "What? A person like you who can be arrogant in the world has only been practicing until he was 90 years old. You have learned all the Yin Nine Methods? Then what level has the Yang Nine Methods... been practicing to??"

"well……"

Old Man Li shook his head gently and said, "If I talk about the Nine Yang Methods, I will be extremely helpless! Because at the age of ninety, after I comprehended the Nine Yin Methods, I began to constantly explore the mystery of the Nine Yang Methods!"

"But no matter what method I use, no matter how hard I practice! During the whole five years, I actually had no understanding of the first realm of the Yang Nine Methods and could not understand it!"

"So, just to live a little longer, I understand now that this fucking Yang Jiu method is definitely not something for people to practice! In the thousands of years since our Tianji Sect was established, only the ancestors have practiced it, and others have no idea of ​​being involved in it!"

"After all, I have now cultivated the Yin Nine Techniques to great success and have become the number one medical master in China! In this way, I have given up the idea of ​​practicing the Yang Nine Techniques! Otherwise, if one day someone can't think about it and will be frustrated to death, then he would be unjustly!"

Seeing that Old Man Li was so indignant, Bai Yi felt even more curious at this moment!

He couldn't help but say, "I really didn't expect that there is such a difficult medical technique in this world! I'm really eye-opening. It's the first time I heard it!"

Old Man Li also looked emotional and said, "This world is the world! Even if an ordinary person spends his whole life, it is absolutely impossible for him to understand too many things! However, these Yin Nine Techniques can actually be practiced."

Speaking of this, Old Man Li's eyes flashed with disdain and said with a smile: "But, at your current level, I'm afraid you want to practice to the first level. After twenty or thirty years, I guess you won't make any achievements! I think you'd better give this book back to me earlier!"

"Are you making fun of me? I'm very talented!"

Bai Yi tightly protected the ancient books, a look of determination flashed in his eyes, and said, "You can show me yourselves! I might have an enlightenment that day and practiced the Nine Yang techniques! By that time, you will kneel down and call me to be the ancestor!"

"Ho! He is really an arrogant and ignorant junior!"

Old Man Li and Ling Wanzi confirmed their eyes, and then continued to remind: "This is the treasure in our Tianji Sect after all! You must not lose it! And don't let anyone take it away!"

Bai Yi nodded and smiled and said, "Don't worry about this! I will memorize all the contents in this book later! Then I will return the book to you for custody, and then I will understand it slowly. Isn't that a problem?"
