The Yin-Yang Demonic Path

[No-System Genius Protagonist]

A tome of demonic arts, a volume of ghostly music.

Fate arrives in a rush, impossible to predict.

What different sights will these two Dao seekers, supporting each other along the way, encounter on the road to immortality?

P.S. This is a mortal cultivation story with an invincible villain protagonist.

Later on, the story expands to the Myriad Worlds, taking a different path from the later parts of typical mortal cultivation tales.
