The Immortal Warlock

This is an era where games have invaded reality, a time of talent awakenings. Aiden Xu, a poor high school student, carries a secret: he can heal infinitely. To successfully undergo his Class Awakening, Aiden Xu trades his lifespan for money and awakens as an SSS-class Warlock. However, he is hunted for his extraordinary talent. Relying on his cheat-like ability of infinite healing, he crazily increases his strength and brutalizes his opponents.
