Invincible, but You Have to Be a Mortal

New Books Self-Recommended by Newcomers, Traditional Immortality Cultivation, Fantasy, Soul Cultivation, Sword Cultivation, and Gu Cultivation

I want to read a book similar to "Sword Out of the Soul". The male protagonist is very handsome, but also very depressed. He has no spiritual roots but awakens the supreme soul power first. He practices the "Anti-Entropy Soul Art" and gains the ability to control the soul, but what is the purpose of controlling the soul?
