Among the people in this room, although Su Chan heard his master say a lot about the cultivation world, she knew little about the waidan sect. Li Yundong practiced for only half a year, and her eyes were black, not to mention Zhou Qin.

Zhou Qin listened attentively. She suddenly asked, "what is waidan sect? Is it a sect specialized in practicing pills?"

Ziyuan smiled and explained: "In terms of cultivation methods, the cultivation world is divided into Neidan sect and waidan sect. Neidan sect respects our Zhengyi sect, including Jinshan sect and Danding sect. Waidan sect respects Gezao sect, including Maoshan sect and Qingwei sect. Neidan sect focuses on human inner Dan, while waidan sect focuses on taking immortal pills."

Zhou Qin suddenly heard this, but her face was still a little strange. It was obvious that she had just come into contact with the world of practitioners and was a little uncomfortable.

Zhou Qin looked at Li Yundong and asked, "are you from Neidan sect or waidan sect?"

This sentence stopped Li Yundong. He felt that he began to practice formally after taking Renyuan gold pill. He should be regarded as the external pill school, but his internal pill practice is very solid. It seems that he should also be regarded as the internal pill school.

Li Yundong thought for a while and confused himself. Ziyuan smiled and helped him out: "Li Yundong should be a master of external Dan sect and internal and external cultivation."

With that, Ruan Hongling suddenly snorted and said, "if there is no yuan Jindan and my sister Ziyuan's jiuzhuan Yulu pill, how can you improve so fast!"

This sentence made Li Yundong's heart suddenly move. He looked at Zhou Qin, his eyes twinkled, and his thoughts kept on: if only there were another Renyuan gold pill, it would be good to give it to Zhou Qin, which would also be a reward for her kindness to break down the family and bear the disaster for me.

Ziyuan glanced at Ruan Hongling faintly, with a warning in her eyes. She said to Li Yundong, "I believe you can also understand how much an external pill can help you in your practice. It can be seen that a fairy pill is a treasure that all practitioners dream of."

"Because waidan is so important and can produce huge economic benefits, the sect has a valuable alchemy technology, so in order to control the profits of this industry, they must control the upstream of the industrial chain, that is, all kinds of precious Chinese herbal medicines. Only when they control this piece can they have enough raw materials to refine all kinds of pills. Otherwise, if this industry is controlled by others, Then the waidan sect is not far from extermination. "

Li Yundong suddenly said, "I see. The waidan sect regards this piece as their own forbidden land and does not allow others to touch it, does it?"

Ziyuan nodded and said, "it's true. Because of this, the inner Dan sect and the outer Dan sect have fought secretly for several times. The birth of their predecessor yuan Jindan in a few months has caused a bloody storm in the cultivation world, and even the fox Zen sect has been involved." when she said this, Ziyuan took a meaningful look at Li Yundong.

Su Chan and Ruan Hongling both set their eyes on Li Yundong, and their eyes were complex.

Li Yundong said with a smile, "what do you think I'm doing? You've said so much about Ziyuan. You just want to say that it's not good to make traditional Chinese medicine. It will cause conflict with waidan sect."
