Lin You sighed and ran after him. The two walked along the corridor for about ten minutes. Suddenly, they came to a large round room.

There is no way to go in this room. It is empty all around. There is only a futon of yin and Yang in the middle. The walls are full of characters carved from ancient seal script. These characters are chiseled into the walls one by one. The handwriting is elegant and natural, and the strokes are strong and powerful. Although Li Yundong doesn't understand calligraphy, he still feels a rush of momentum of walking around.

Lin Youfa walked into the room and was stunned: "there's no way? How is this possible? There are so many magic weapons and secrets of fox Zen? Where are they hidden?"

He was surprised and anxious. After holding the oil lamp to light up all the oil lamps on the walls of the room, he frantically looked around for exits and mechanisms, but he looked around, but he never found any abnormality.

Lin Youfa said angrily, "how could it be! How could there be no way! It's impossible. There must be a room! The fox Zen gate can't be so poor!"

Li Yundong looked at Lin Youfa and walked around in such a big stone room. He said in a deep voice, "don't look for it, there will be nothing else!"

Lin Youfa turned fiercely, looked ferocious, and said loudly: "impossible! This news will never be wrong, otherwise why did the six sects siege fox Zen gate! So many sects want to pick up bargains! Fox Zen gate must have hidden these Dharma treasures when it learned that the six sects were siege. Damn, it must be so!"

With that, Lin Youfa punched the ground angrily, shaking the ground gently.

Li Yundong looked at him and shook his head secretly. His only worry was that he couldn't get to the fox Zen gate in time.

But he looked left and right. He couldn't see any exit, so he turned his attention to the words on the wall. He recited silently in his heart.

At the beginning, he found that the text could not be read smoothly, but after reading it several times, he found that the text should be read from right to left and from top to bottom, which is the oldest way of reading.

I saw the larger text on it saying: "the power of one turn is like a pearl, and the mountains and rivers are transparent to the soul. The red lotus leaves hide the Dan cave, and the red water flows through the nine waiting beads."

Li Yundong silently recited the poem once in his heart. Some didn't understand the meaning, so he continued to look down and saw notes written in smaller characters below.

It says: the skill of internal alchemy starts from one and becomes nine. One is the birth of all things. The heaven generates water, the earth generates fire, the heaven generates wood, the earth generates gold, and the heaven generates earth. The sequence of the five elements starts from one. Therefore, the skill of internal alchemy also starts from one and turns into nine. Nine is the pole of the number of Yang. As for the number of nine, the Tao is successful.

Seeing this, Li Yundong felt a sudden shock in his heart. He unconsciously opened his mouth and shouted to himself: it's actually an ancient book of practice!

Li Yundong hurriedly looked down again. Sure enough, he saw that the following wrote: human beings are formed by the * * of father, essence and 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.
