Ruan Hongling said angrily, "if sister Ziyuan didn't let me see you, would you think I'd like to come and see your dead face!" she said, throwing the plastic bag heavily on the table.

Li Yundong raised his eyebrows and was about to speak, but he saw that the aster also flew over from the balcony. Li Yundong couldn't help smiling bitterly: why don't these two women have the habit of going to the front door?

Ziyuan whispered angrily, "Hongling, practitioners should pay attention to self-cultivation. You have such a big temper. How can you practice?"

Ruan Hongling snorted angrily, pointed to Li Yundong and said, "if he wasn't angry with me, would I be so angry?"

Li Yundong didn't look at her either. He snorted coldly, "you asked for it yourself."

Ruan Hongling stamped her feet angrily: "sister Ziyuan, look, look!"

Ziyuan said with a wry smile, "you two should say less!" then she looked at Li Yundong and said, "look, you've been watching it all day and night. Do you understand what the truth is?"

Li Yundong immediately brightened his eyes, nodded excitedly and said, "I understand a lot of things. For example, what you said before."

Ziyuan smiled and said, "Oh? Explain?"

Li Yundong explained: "the Yellow Emperor's Internal Classic" It is believed that the five senses belong to each other. The eyes belong to the liver. Once the eyes are closed, it is equivalent to closing the liver valve in the body. The blood flow of the human body will slow down and the consumption of essence and Qi will slow down. In other words, the metabolism will slow down, so the excess strength and energy will be stored. This is the meaning of closing eyes and nourishing the mind. "

Ziyuan smiled and said, "well, you go on."

Li Yundong added: "As for shopping, it comes from the corresponding five elements of gold, wood, water, fire and earth in the East, West, North and south. Among them, the things correspond to wood and gold. In the gold, wood, water and fire and earth, in ancient times, wood and metal can be made into things and used as commodities for exchange, while the north and South correspond to water and fire. Water and fire can't be bought and sold, but gold and wood can. So it's said to buy things instead of North and south!"

Ziyuan nodded admiringly: "well said, is there anything else?"

The more Li Yundong said, the brighter his eyes were. He felt that a strange but very familiar door of practice was slowly opening to him. The world inside was not unknown to him. On the contrary, it was all familiar to him, but he had to understand these things from another level.

He said, "as for why we say essence, blood, sperm and essence instead of Qi, blood, son and yuan, it is because of the Yellow Emperor's Internal Classic." It is believed that essence is the most important thing in the human body. It is the essence of human being. It is essential to have essence, talent, essence, blood and intelligence. Therefore, it is the first thing to be ranked in the forefront of words, not to be followed by it.

Ziyuan immediately asked, "do you know the difference between essence Qi, essence blood, sperm and essence yuan?"

Li Yundong also immediately said without hesitation: "essence refers to the relationship between the kidney and the meridians. If the kidney can't hide essence, the Qi in the meridians will weaken. Once this Qi weakens, people will have no strength, so there will be a lack of energy and essence. This person is listless."
