When the last Law reached the standard, Du You felt a special state enveloping his own being. It was a mystery beyond mysteries, which brought Du You into a strange realm.
If Du You could feel his own body now, he would find that it was undergoing a unique transformation.
This transformation began with his soul. Originally, his soul was but an illusory thing, perceptible yet indistinct even upon introspection. Later, as he grasped the rules, the soul began to slowly coalesce. Previously, the soul had gathered into a sphere until he started comprehending the Law.
As the lines of the Law were outlined, the soul itself became a materialized orb, which was the prior form of Du You's soul.
Now, the soul orb started to change, twisting bit by bit as the Law lines grew and then began to circulate. This circulation appeared to be polishing and processing the soul itself.
Under this polishing, Du You's soul began to twist and change shape bit by bit, becoming more solidified.
