Ghost Hunter: I Swallow My Companions and Turn Them into Ghosts

In the 298th year of the Spiritual Age, human beings were hiding in seven giant cities to survive. The Thunderfire Association rules over all hunters, Twelve ghost moons await extinction in the misty forest. And I gained the power of devouring in the trial of blood and fire—— Devouring ghosts can inherit their abilities, But the effect of devouring hunters is ten times that of ghosts. I kill teammates who trust me, Betrayed the female instructor who admired me, Flirting between the association and the ghost realm, Just to climb to the top of power.
