The technique of inhaling through his nose and exhaling through his mouth was as simple as eating and drinking to Xu Tui.
What was a little foreign was visualization. This was a little difficult for him.
Other people would really visualize a dried-up lake in their dantian in their minds. However, Xu Tui immediately entered the introspective state the moment he closed his eyes and started visualizing. He saw the state of his body.
In the realistic introspective state, the so-called dantian was at the lower abdomen. There was no dantian in the skin, peritoneum, internal organs, or blood. His consciousness changed slightly and entered the illusory introspective state.
In the illusory introspective state, his lower abdomen was covered in gray, inactivated Genetic Base Points. He did not have a dantian. However, Xu Tui had read most about the concept of visualization in the books that Luo Murong had lent him.
