Soul, a unique existence for each person.
But Bai Xin has two souls and consciousnesses, one good and one evil, that share and integrate.
Ghosts and souls mutate, causing them to stay and harm people.

But as the strength becomes stronger and stronger, he explores the essence, breaks the shackles based on his own everything, and reaches infinite existence.
Intention: good and evil
