Lee Junghoo died in a car accident. He braved each and every hardships in Jaiden’s body in hopes that he would survive once he cleared the game of the gods but just when the Empire’s strongest family was about to fall and killed by the monsters…

He meets a passerby who is enlightened by him and becomes an immortal sage who leads an entire generation.
