[A vast world of demons, monsters, ghosts, and spirits + transmigration + uncanny power-ups + growth through devouring]
Zhao Wuji transmigrated here from another world after a spirit-summoning ritual. He awakened his shadow's mutated devouring ability, allowing him to devour demons, monsters, ghosts, and spirits to strengthen his body, devour martial artists to gain martial experience, and devour cultivators to gain cultivation experience. Thanks to his unique bloodline, he ultimately became a terrifying existence.
[My surname is Zhao. Wuji means having no scruples.]
[Demons, monsters, ghosts, and spirits, hurry up and let me love you properly.]
[The uncanny things today aren't very tasty, just a little spicy.]
[My recent power-ups haven't been satisfying. Guess I'll just eat another haunted city.]
