The Hero's son and the ghost of the Demon King are the master and disciple!?

Earth, the son of Hero, the Hero who defeated the Great Demon King, is troubled.

Living every day like this, Earth meets his destiny in the room containing his father's sword.

“Interesting. I will train you. I have only free time now.”

Earth receives special personal training from the Demon King just to get back at his parents and the world.
In the coming days, his parents, the heroes of the past, his first love, his princess childhood friend, the geniuses of the era, and the world will tremble before him.
