The Demon Prince goes to the Academy - Chapter 1

“I can’t accept this! I can’t! Even as a ghost, I’m going to spend eternity cursing that your relationship will shatter like glass! Break apart like a pair of mandarin ducks that fly away from each other!” With such a persisting obsession, it would be difficult for the vengeful departed spirit to move on.

“Shameless Xia Ping, not only did you steal my martial arts manual and medicinal pills, you even took my fiancée! We’re not finished!”

“He’s the embarrassment of the Martial Way and a parasite of the human race. A complete scumbag.”

“There’s nothing that he won’t do. Not only would he not help an old person cross the road, he would even steal the lollipop of a three year old.”

“He causes problems everywhere. All of the geniuses of those big families have been beaten up by him before. Now, he’s no longer tolerated by either humans or gods!”

Countless martial arts experts of Yanhuang Star hated Xia Ping down to the very bone. They were just itching to completely crush him into pieces.

As for Xia Ping? Facing the hatred of so many people, he just calmly pulled up the interface of the “Grand Hatred System” and looked at all the wonderful things there. He rubbed his chin, “I’ve already saved up so many Hatred Points. What should I exchange for now? Saint-grade medicinal pills? Or perhaps that Primordial Pill? The peerless martial art skill, Tathagata Palm also seems pretty good too. But then there’s that divine weapon, the Cosmic Cauldron. It really is too difficult to choose!”

Kyle woke up in a land of fantasy and magitech. The usual 'I died and woke up' bullshit, skip all that.

Except he used to be a crime lord, and society here is missing that extra kick.
