Jessie, still powerless and stunned, can only watch as her life slowly fades.Frustrated by his helplessness and lack of strength, he suddenly hears a sound echo in his mind:[DING!][“Supreme Check-In System initializing... 1%... 100% complete.”]A voice rings out in his head, calm and mechanical—but filled with promise. The Supreme Check-In System has fully loaded. Its ability? Every time Jessie sets foot on a new island, he receives a heaven-defying reward.Stunned and thrilled, Jessie asks, “Do I have a novice reward?”[DING!][“Yes. Claim with your mind.”]Without hesitation, he shouts in his thoughts, “CLAIM!”DING![Congratulations! You have received the Sword God Inheritance (MAX)][Congratulations! You have received the 3-Domineering System (MAX)][Congratulations! You have received the One Fruit: Supreme Resurrection System]Eyes wide and heart pounding, Jessie grins with uncontrollable joy.“System, I love you so much! You’re the best! Hahaha!”With unimaginable power now coursing through him, Jessie sets his sights on rewriting destiny—starting with saving Uta, and eventually challenging the very balance of the seas!

“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!”
