Toaru Majutsu no Index SS - Volume 1, Chapter 1: Pot with Meat and the Appetite for Great Tactics. A_Required_Thing.

Humanity achieved dominion over the galaxy long ago.Once that was accomplished, they turned their ingenuity inwards. With their prowess over biological engineering, they transformed themselves into deific beings now called the Gene Tyrants. For centuries, the Gene Tyrants terrorized the galaxy, designing and abusing their genetically engineered servants and serfs as their whims took them.No tyranny can last forever, though, and the Gene Tyrants were eventually overthrown. The rebels discovered a strange light of the mind called Aether, which gave them the strange and fantastical powers they needed to eradicate their creators. Once that was done, however, that by no means meant peace.In the thousand years since, the face of the galaxy has changed. The most powerful human civilization is called the Supremacy, the homeland of 'might makes right'. In the Supremacy, a crime committed by the strong is no crime at all. With their military strength and mastery of Aether, the Supremacy has spread across the galaxy -- with the other powers able to do little but stall their advance. This struggle has developed into a cold war, and that cold war has frozen over for years now.Dragan Hadrien, a low-level administrator in the Supremacy, cares nothing for any of this. Dragan's primary concern is getting himself a promotion and taking it easy for the rest of his days. When a mysterious prisoner is brought aboard his ship, he thinks he has found the means to do just that.How naive of him.

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!

The first time Yan Zhaoge crossed worlds, he landed in a martial warrior civilization that was at the peak of prosperity. He ended up in the book storage building of the the Divine Palace, which collected and preserved the classics of the entire world from all fields of knowledge. However, a world class calamity struck soon after and even the Divine Palace was destroyed.

Yan Zhaoge’s soul once again crossed over, but this time he arrived in the same world, except countless years have passed.

With his brain full of rare books and classics from the era of peak prosperity, Yan Zhaoge’s second crossing over to the present era was like a gamer who was used to playing hell mode suddenly finding himself playing the game on easy.

That was just way too awesome.

But before that, he needs to fix a certain problem.
