Ziyuan and Ruan Hongling looked at each other and secretly praised the boy's understanding and transparency. Ziyuan nodded and said, "good, continue!"

Li Yundong was encouraged, and he became more and more aware in his mind. The things he knew before were hooked with the seemingly ethereal things, and he became more and more excited.

Li Yundong said: "as for blood essence, this refers to the relationship between the liver and kidney. The kidney stores essence, and the liver stores blood. Although the liver ranks higher than the kidney in the five zang organs, if people want to produce essence, the liver will produce a lot of fresh blood, so as to convert these blood into essence. Therefore, there is a saying that one drop of essence and ten drops of blood, which shows that essence is higher than blood."

Ziyuan smiled and nodded.

Li Yundong added: "sperm refers to the relationship between the causal logic of reproduction. There is sperm first, and then children can be born. The causal logic can not be reversed, so the word can not be reversed."

Ziyuan said with a smile, "what about Jingyuan? It's not easy to explain."

Li Yundong thought for a moment and said: "This is actually easy to explain, because essence refers to the causal logic of practice. People must have essence first, so they can have Qi, blood and God! If the human sperm is constantly consumed, then the person must consume a lot of Qi and blood to produce sperm, which will cause loss and weakness in the human body. That's why it is said that people are hollowed out by women The reason for this. "

"According to the theory of practice, if people consume sperm continuously, then Qi and blood will also be consumed. The essence of Qi and blood, the three essence of the human body, will naturally be greatly depleted. This loss will not achieve the goal of" Sanhua ", and it is impossible to turn three great essence into God. Without essence, there is no God. It can be seen that there is a causal logical relationship between essence and yuan! The order of the two can not be reversed! "

When Ziyuan heard this, he couldn't help but applaud: "wonderful! I didn't expect you to understand so much after only watching it for one day!"

Ruan Hongling also stared at Li Yundong and said in her heart: this man is really talented. No wonder he entered the country so quickly. He can understand so many principles in just one day. It's amazing. It's really amazing!

Li Yundong listened to Ziyuan praise himself. He smiled and said, "in fact, these principles are very simple. It's like only a layer of window paper. You can understand them with a gentle poke. Once you understand them, it's nothing great."

Ziyuan smiled, looked at the plastic bag on the tea table in the living room and said, "here's the food for you. You haven't eaten all day. Eat it first."

Li Yundong only felt excited and didn't feel tired and hungry at all. He said, "I want to see it again. I'm not hungry at all."

Ruan Hongling couldn't help but say angrily, "Hey, I've worked hard to buy you rice, but you don't want it!"

Ziyuan shook her head slightly and said softly, "it seems that you still don't understand the Yellow Emperor's Internal Classic and what is practice."
