Yue Xiuzhi played the most hated villain in Q*dian for the sake of resurrection—— The master of the protagonist, who abused the protagonist in various ways in the early stage, was finally killed, but he couldn’t go back.

In order to compensate, the system sent him to the second world of this book, where Little Protagonist was only five years old, and Yue Xiuzhi could OOC casually, ignoring any plot.

So, Yue Xiuzhi happily spoiled the wolf cub.

But he didn’t know that the protagonist of the body world who was abused by him in various ways would occasionally possess the Little Protagonist in this world.

This Son of Heaven was surprised to find that the hypocrite master, whom he hated so much, actually pampered the “self” of this world.

He had been tortured in various ways because of his demonic nature, but the master of this world, after discovering that “he” in this world had demonic nature, said: “Demon qi and spiritual qi are just a form of energy. Spiritual cultivation and demonic cultivation are just a way of pursuing the Dao. In spiritual cultivation, there are people with human faces and animal hearts, and there are demons who have clear grievances.”

He became jealous but did not want to admit it, in the step by step fall, he found out that the person who died for him, his best friend, his first love, and his most hateful master, were actually the same person!

An extra with no screen time, no future, and worst of all… no real strength.His so-called Talent Ability—Command—doesn’t make him stronger. Instead, it grants a 300% boost to the abilities of those who are bound to him and follow his orders. A powerful buff, but utterly useless when he is weaker than even the lowest-ranked students at Zenith Hero Academy.Thrown into a world where strength is the only law, Severin quickly learns that if he can’t fight, he’ll be crushed. Refusing to accept the fate of an extra, he turns to manipulation, deception, and blackmail, using his intelligence to twist the battlefield in his favor. If he can’t be the strongest, he’ll control the strongest.With the looming threat of world-ending catastrophes and prodigious heroes destined to take center stage, Severin must navigate the deadly hierarchy of the academy. He will recruit, betray, and outwit both heroes and villains—because in a world where power is everything, strategy is his only weapon.And one thing is certain: he refuses to die a nameless extra.

Aoki’s resolute face was indifferent. “If the sun doesn’t shine on me, please let me be surrounded by darkness!”
