Listening to Others Bragging, I Became the Strongest Person in the World

[Decisive killing + no pressure on the realm + high excitement + revenge that does not last overnight] Yang Kai traveled to the dangerous world of Gaowu. There were cracks in the sky and ferocious beasts in various wilderness areas on the ground. After the awakening ceremony at the age of eighteen, he discovered the real reason for the death of his parents. It was all because of a mysterious combat skill, and he was assassinated and robbed by the local powerful Zhao family. Just when Yang Kai fell into despair of being unable to avenge his parents, the rumor materialization system that had been delayed for many years arrived. Just hearing someone bragging can make you stronger. Since then, Yang Kai has been invincible all the way, reaching the ninth-level martial artist realm in one day and the ninth-level martial master realm in three days. Before entering university, he was already a strong warrior in the general realm. Passerby A: "Have you heard? Not long ago, senior Ye Fan broke through the Wuzong realm at the age of forty. He can be said to be the youngest grandmaster in China and even the entire Blue Star." Passerby B: "Tch, what is the Martial Saint Realm? In other words, Master Lin Yan is the most powerful. He broke through to the Martial Saint Realm at the age of fifty. Compared with him, Ye Fan is also a little behind." System: "Ding! Two rumors that can be realized have been detected and are being optimized for host deduction. They can realize the first-level Martial Sect Realm and the first-level Martial Saint Realm." Yang Kai: "What? What are you talking about? Go on, don't listen. If you brag a few more times, I can destroy the vicious beasts of Blue Star and the cracks in the cave alone. A forty-year-old Martial Sect? A fifty-year-old Martial Saint? Have you ever heard of the eighteen-year-old Martial Emperor Realm?"
