In 2030, an anomaly transpired, and aliens invaded the earth! At this age where the world was about to be destroyed, the top talents of mankind gathered from all over the world to develop a holographic game called Miracle. All humans on Earth would enter this game and battle against foreign invaders through holographic simulation. After Mike entered this game, he unexpectedly discovered that he could actually see all kinds of hidden information.

[Beginner-tier Exotic Beast, Level: 1, Status: Weak…]

[Boss-tier Exotic Beast, Level: 10, Status: Berserk...]

[Overlord-tier Exotic Beast, Level: 15, Status: Idle. Will drop a piece of SSS-grade weapon when killed... ]

[Old wooden crate with hidden SSS-grade equipment...]

From then on, Mike used the system to quickly level up in Miracle. Gradually, when he looked back, he had become the world’s greatest existence!

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!
