Venerable Li Tian has followed Lu Yi for all these years, and he has seen what Lu Yi has done, and Lu Yi sometimes tells his troubles and thoughts to Venerable Litian, so Venerable Litian still knows Lu Yi better, with the knowledge and experience of an old monster like Venerable Litian, why can't he see what kind of life Lu Yi is? Venerable Litian has actually treated Lu Yi as a disciple all these years, and taught Lu Yi his knowledge in the formation path and cultivation without reservation, Lu Yi also respects Venerable Litian, the relationship between the two is more of an inexplicable family affection in the eyes of Venerable Litian, he completely regards Lu Yi as his son, nephew and even grandson, and his care for Lu Yi is far greater than that of Lu Yi's teaching in cultivation. Therefore, when he heard that Lu Yi was going to risk himself, he couldn't help but worry about Lu Yi's safety, and planned to bear the crisis for Lu Yi himself.

Lu Yi was silent for a while before he spoke: "I really understand the kindness of my predecessors, but I still want to use my own strength to open up the second dantian, you also know, only my own things can grow with me, moreover, I just looked at the things in the jade slip, which provides several better physical training techniques than what I am practicing now, including the exercises practiced by the human monks who successfully opened up the second dantian, so the juniors' hearts are a little itchy, and the juniors want to practice those exercises." As for the matter of opening up the second dantian, the younger generation wants not to be in a hurry for a while, and the younger generation is not a reckless person, and if he is not completely prepared, the younger generation will not take this step. ”

Venerable Litian didn't know Lu Yi's careful thoughts, he sighed helplessly and said, "Hmph, you kid won't listen to me anyway, you have your old idea, it's useless for anyone to persuade you." Maybe this time this is also a calamity in your life, I just hope that you are really the person of destiny, and you can be blessed and survive this calamity smoothly. If that's the case, maybe your kid will really soar into the sky. ”

The two finally reached a consensus, and Lu Yi began to tell Venerable Li Tian about the four physical exercises selected by the Psychic Demon Lord in the jade slip, and asked Venerable Li Tian to help him choose two of them to practice, especially the exercises that had helped a Terran disciple of the Psychic Demon Lord successfully open up the second dantian, which was the focus of research by one old and one young.

For three years, Lu Yi and Venerable Li Tian were almost day and night in the practice of practicing the body left by the Psychic Demon Monarch, and finally determined the once successful body practice technique called "Ten Thousand Refining Rebirth Dafa" and another one called "Shaping the Meridian and Expanding the Pulse" as the next cultivation object.

These two exercises are used to build a strong body, and the other is to continuously expand and strengthen one's own meridians through accumulation, but they complement each other.

After some careful preparations, Lu Yi decided to start cultivating the "Ten Thousand Refinements and Rebirth Dafa". As the name suggests, cultivating this method is very arduous, and it needs to go through countless cycles, and each cycle is a process of putting death and then rebirth. In each cycle, the skin of oneself must be completely removed, all the bones are shattered, and soaked in a special medicinal liquid refined for the purpose of body training for nine hundred and eighty-one days, and the pain can be imagined.

In order to practice, Lu Yi spent nearly fifty years traveling all over the Northern Regions, collecting enough materials to refine medicinal liquids and maintain and repair his body, and he also refined a large number of pills, so that he could take a step forward in his Dan skills and successfully achieve the seventh-order Dan Master. After nearly 100 years of preparations, Lu Yi finally decided to take the first step.
