Martial King's Retired Life - Chapter 110Book 15:

“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!”

I was the awakened on the path to become the strongest, but instead, I became the final boss of an Eroge.Pushed into the body of Eugene Hall who was but a petty villain that somehow spelled the end of the World, I had to live again in a world of demons and gods.Moreover, the main characters were all regressors who wanted me dead.Now I was stuck as a villain with heroes and villains, demons and gods all coming after my life. And even beyond them were the oncoming outer gods that wanted the world gone.And honestly? I didn't care.My path was the path to the strongest! Nothing else could come in my way!!

This is a bizarre and mysterious world filled with various sinister cultivation methods. Once a person begins to cultivate, they will either undergo mild changes in appearance and temperament, descend into madness, or become a great elixir for evil beings to consume...Duan Yun, having transmigrated into this world, unexpectedly comes across a supreme elixir cultivation manual, the 'True Explanation of the Jade Sword.'To his surprise, he is a one-in-a-million cultivation genius who, unwittingly, transforms the manual into something extraordinary. Guided by the Jade Sword, he is able to pierce through everything.Later, as his mastery over various methods grows, Duan Yun, carrying the philosophy of 'the enlightened benefit the world,' never keeps secrets and spreads martial arts across the land.Who would have thought...“Duan the Demon misled me! He said this technique enhances yin and yang, but now I can only squat to pee, boo hoo...”“It was the Demon who taught me this 'Seven Parts Returning Qi'. Instead of blessing me, it brought disaster—I either get killed or step in dung. The fortune-teller said I've lost seventy percent of my luck.”“Don't trust a word of what Demon Duan says! The fairy of the Myriad Wonders Palace was supposed to ascend the whole palace to the heavens, but in one night, she was possessed and turned into a demoness, all due to that old demon Duan's handiwork!”...Duan Yun finds this incomprehensible. All he did was practice martial arts, spread techniques, and occasionally emulate the laws of nature, so how did he become notorious as a demon?This is slander!The same techniques cause no issues for me, so the problem lies with you all, not me!
