Chapter 990

Seeing here, Li Yundong couldn't help but applaud the case!

Since he succeeded in building the foundation, he has read many ancient books of practice, but none of them explained Neidan very clearly. Either they explained it very deeply, covered with clouds, mountains and fog, or they explained it very astringently, making people confused.

But this sentence clearly explains what's going on with people and what's going on with Neidan!

How do people come? It's very simple. Men and women come from sex. This is behavior mating, so it's called line intercourse. How does Inner Alchemy come from? It's made of heart fire and kidney water in the breath of the five internal organs, so it's called Qi intercourse!

LV Dongbin also wrote a poem saying that there is heaven and earth in his own universe, and his heart is more than heaven, and his kidney is more than Earth. It can be seen that the combination of heart and kidney qi is the cultivation method of the combination of heaven and earth!

As soon as Li Yundong wanted to understand this truth, it seemed that a valve was opened in his mind. With a roar, all his knowledge was integrated. It seemed that there was a basin of hot water pouring down his head from head to foot, just like refreshing, which made him very excited!

Li Yundong shouted loudly in his heart: who is the great overhaul pedestrian who wrote this? He explained the word of practice so clearly and incisively! Great, that's great! This must be a Taoist book. This book must be the supreme Scripture of practice!

Li Yundong's eyes widened with excitement and continued to look at the words on the wall. He saw the words with larger characters engraved below, which wrote: "two turn Yang into Yin, and the kidney light heart liquid combines Ding Ren. When the divine pearl ran to the East China Sea, it burst into spiritual light and illuminated purple gold."

Then the following is the explanation in small font. When Li Yundong saw jiuzhuan all the way, he wrote: jiuzhuan is carefree, daoguoquan, and three thousand skill lines are immortals. The Golden Book and jade slips proclaim the imperial edict, and the auspicious clouds stop the nine days!

Seeing here, Li Yundong's last eye is the words written by a line of engravers.

This line of words was written with wild grass. Li Yundong saw it, and he only felt a momentum of defiance, arrogance and arrogance.

It says: in the 15th year of emperor Xi Zong of the Tang Dynasty, Mr. Ni Wan Chen Pu created the nine turn golden elixir technique. This technique captures the creation of heaven and earth. It is a secret treasure of practice. I yearn for it, but I don't want it. However, I spent a lot of effort and traveled to China for more than ten years. It was recorded here in the third year of Qianhua of the Later Liang Dynasty.

After these words were written, Li Yundong finally saw the signature of the engraver. He saw that the signature was flying like a dragon and flying like a Phoenix. He wrote four words: Secret of heaven and xuanhu!!!

Seeing the last four words, Li Yundong was completely shocked. He didn't expect that the writing in front of him was written by xuanhu, the strongest but most controversial secret of fox Zen!

Li Yundong couldn't help walking to the wall and stretched out his hand to touch the wall. He just felt that the tentacle was very hard. It was the hardest granite!

He reached into the chiseled writing groove and touched it, but he was surprised to find that it was engraved by people's fingers!

This is a big surprise!

Li Yundong couldn't help but be shocked: is this carved by human flesh hands? Well, how is this possible?
