Sato Yu is a 12-year-old boy. He is a deprived person. His life is depriving. His step father has a large amount of debt.

“My daughter will kill me.”A poor man, exhausted and overwhelmed by debt, dies and finds himself in his favorite novel as Arzoth Draven—the character he despised the most. Arzoth Draven is the infamous prince who constantly tries to undermine his brother, Evren Draven, the story's main protagonist. He abandoned his illegitimate daughter in a basement, only to be killed by her years later. Now, having transmigrated into the role of Arzoth Draven, can he avoid this grim fate? And on top of that, he also possesses a system.

Since then, Beiyuan Baiqiu has embarked on the road of being invincible.
