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…

1 Stop the destruction of the continent.

2 Survive until the age of 35.

And the first step for him to achieve this was to leave this crazy family of his.

“Maybe the answer is running away from home?”
