And she once asked Old Mr. Bai about the essence of this realm.
Old Mr. Bai replied to her that it is the fusion of body and soul.
Although the new body is created by the power of laws from imaginary to real, it is incredibly in tune with the soul. Only when the soul and body completely converge, will one reach the Yang Transformation stage!
Thinking of what her grandfather taught her, Bai Zhi couldn't help but contemplate her current situation: Now she has reached the Spirit Ascension stage without wasting her physical body.
However, she clearly hasn't reached the realm of perfect fusion of soul and body at the Yang Transformation stage.
'So... should I now let my soul and body fuse?'
With this thought, Bai Zhi recalled the three stages of Spirit Ascension recorded by her family [Spirit Structure] [Physical Body] [Yang Union] and the order of organ fusion.
