I Picked up the Ancient God of War at the Beginning and They All Called Me the Savior.

Psychic awakening? No, you inherited the last words of the ancient god. When the resurgence of spiritual energy is proven to be the "mass graveyard" of ancient civilizations, every super power you control is the unfinished obsession and memory of a departed soul. In this ruins composed of human spiritual bones, the protagonist awakens a silent god of war - he is an ordinary college student on weekdays, but in critical moments, he takes the initiative to fight and displays the lost god-slaying martial arts. It wasn't until forces from all sides came to his door that he was shocked to realize that the tenant in his body was actually the sealer himself who sewed up the "Crack in the Sky" a hundred years ago. And that crack began to disintegrate for the second time because of his awakening - the hundreds of millions of dead souls of the old civilization will soon claim everything they have from the new world through his body.
