Li Yundong intruded into Su Chan's Xuanyin virgin with the body of the boy Yuanyang, which was like the combination of Yang Ding and Yin Ding. The two best Ding furnaces in the world were integrated together.

Men's words were called "Yang root" by the ancients. As the name suggests, they are the root and root of Yang Qi. They are the place with the heaviest Yang Qi in men's whole body. If they are cut off here, they will become eunuchs. Men are not men, women are not women, and there is no masculinity at all; Women's words are called "* * *". As the name suggests, it is the place where Yin Qi converges. It is the place where Yin Qi is the heaviest in a woman's whole body.

It is said in the nine turn golden elixir that the body of a person is formed by the * * of the father's essence and the mother's blood. It is formed by the falling of Dan, heart fire and kidney water. This Qi is also handed over. Therefore, it is said that if the form is combined, people will be born, and if the Qi is combined, it will become a pill.

Li Yundong and Su Chan are both practitioners. At this time, although they are in physical contact, they are also in Qi contact. As soon as their Yang Qi and Yin Qi come into contact, they are shocked all over, like water and fire.

They just feel that their breath is boiling. When the water is burned, it will boil and roll. Similarly, when the fire is watered, it will also make smoke and flame transpiration.

The reason why the practice world prohibits Fangzhong Shu is because Fangzhong Shu is also a kind of "fighting method" in the final analysis. However, this kind of fighting method looks fragrant and beautiful, but it is actually dangerous and amazing. The sinister part is far better than ordinary fighting methods.

According to the Yellow Emperor's Internal Classic, men are like fire and women are like water. According to the plain women's classic, men and women are better than men, just as water is better than fire.

Women are born strong in the art of sexual intercourse, and men are born weak, because from the perspective of the five elements, water conquers fire, so women conquer men. From a physiological point of view, unless men are gifted or trained the day after tomorrow, they will encounter ordinary women. Most of them will not be opponents and will eventually lose.

Even if a woman loses her armor and pleads for mercy in a battle, after a rest, the woman can regain her strength, but the man may not.

Even if a man can regain his power, in the past, for a few months or years, he will "clearly not see his head fall and secretly teach the king to dry his bone marrow".

Therefore, there is a joke about "only tired cattle, no cultivated land" in the market, but although it is a joke, it simply reveals the secret of fangzhongshu.

Since ancient times, women have been weak in marriage, but most of them are strong in sexual affairs, especially if they know how to lock Yin and pick Yang after practicing the art of sexual intercourse, it is really terrible.

If only one of the practitioners is a practitioner, it is a side-by-side slaughter, killing the other party's Yuan Yang out, or Yuan Yin out, and tonifying himself; But if both sides are practitioners, it will certainly be a war. Even if they have no hostility, the Yang and Yin Qi in their bodies will naturally fight together. In this fight, men will be at a disadvantage at the beginning, because fire is conquered by water.

Therefore, it is said in the Sutra of plain women that a man and a woman are better than men, just as water is better than fire. They know and act like broken cauldrons and tripods, can mix five flavors, and can become a soup, know the way of yin and Yang, and know the five pleasures. Those who don't know will die. How can they be happy? It's careless!
