"Hoy" is full of the power of swords and gods, and "Iao" is developing technology at the speed of light.
The relationship between the two worlds is inextricably linked. Five years ago, Zhizhang, who grew up in "Hoy", suddenly traveled to "Iao" in his room.
Facing the mysteries of the two worlds and driving a large machine, Zhizhang successfully defeated the alien aliens that invaded "Iao" and became a hero in the world.
But when he returned to his original world from Iao, what was waiting for him was not a feast to welcome the hero in triumph.
His own body, his sister who hated him, his fiancée who didn't know why, the scientist from another world who was involved, and the mysterious girl - how will the hero from another world deal with one mystery and another blow?
In fact, the so-called heroes are just mortals when they return to their own world.
