As soon as the grandfather heard that this was a good thing, he said hello to Ding Cheng, and took everyone back with Nima.

Ding Cheng returned to the cave, knelt down and kowtowed to the man, and performed the master and apprentice ceremony. The man pulled Ding Cheng up with his arm and said: "I teach you martial arts, but it doesn't mean that I want to accept you as an apprentice, the age difference between you and me is too big, and it is not appropriate to call me a brother, you just treat me as an ordinary senior." ”

Ding Cheng saw that the man's tone was resolute, and he knew that this person had a strange temper, so he no longer insisted, and bowed down and asked, "But I don't know how the juniors should call the seniors?"

The man said: "My surname is Tang, and my friends in the rivers and lakes who can afford me call me Tang Gong, you can call me Tang Gong." ”

Ding Cheng remembered the name Tang Gong, as if he had heard his father say that he was a big hero of Yuanmou, and he didn't know how he ended up in this step.

After staying in the ice room for a long time, Ding Cheng was a little unbearable, and he felt that his hands and feet were a little numb. Tang Gong asked Ding Cheng to sit cross-legged on the ground. It doesn't matter if he sits down, Ding Cheng felt a cold air from his ass to his head, and he couldn't help but shiver, and immediately straightened his chest, and his luck fought against the cold.

Tang Gong saw that although Ding Cheng's lips were purple from the cold, he still sat upright, so he couldn't help but nod and said, "I'll teach you a set of exercises to resist the cold, you listen well." ”

Then he recited a large number of martial arts mantras, all of which were acupuncture points, tendons and veins. Ding Cheng recited it silently several times, keeping this mantra firmly in his heart, but the meaning was half-understood and not very clear.

Tang Gong taught from the beginning, including the position and function of the major acupuncture points in the human body, as well as the direction and attributes of the major meridians. Finally, I taught Ding Cheng how to breathe and luck.

The set of exercises given to Ding Cheng by Tang Bus is a set of superior exercises that combine rigidity and softness, and under Ding Cheng's concentrated cultivation, he unconsciously forgot the cold on his body.

Ding Cheng practiced in the ice room for a month. During this period, the snowman will often catch rabbits, fawns and other animals, and sometimes bring back some fruits. The climate in the valley is warm and humid, and the two of them do not have to worry about food.

After some time, Tang Gong took Ding Cheng to a waterhole. Ding Cheng looked at this waterhole very strangely, the radius was no more than a zhang, and the water was waist-deep. There is an outlet and an inlet in the waterhole, and the spring water is always in balance in the two springs.

Tang Gong said to Ding Cheng: "You go into the pool and try it." ”

Ding Cheng took off his robe, tightened his clothes, and jumped in at once. As soon as you step into the water, you feel a great suction force that sucks you into the spring, and another spring has a great momentum that wants to rush you to the surface. Ding Cheng was unprepared, and was stirred up in the water by two forces, but fortunately, Ding Cheng had excellent water ability, and barely stabilized his body in the water, and struggled for a long time before he climbed ashore.

Tang Gong didn't laugh when he looked at Ding Cheng's embarrassed appearance, but said very seriously: "The two forces in this waterhole are also two important forces in nature. The power of water is sometimes extremely strong, sometimes extremely soft. As long as you can overcome these two forces, standing in this pool as if you were standing on solid ground, your strength can be considered small.

After that, Ding Cheng spent half of his days practicing internal force in the ice room, and half of his day fighting against water power in a waterhole. Day after day, more than three months have passed in the blink of an eye.
