Surviving as a Genius on Borrowed Time - Chapter 18: Recommendation

Celestial Martial Continent, where powerful individuals gather like clouds, and sects are found everywhere.The anger of a strong individual can burn the heavens and boil the seas, overturn the skies with a wave of their hand, and change the sun and moon with a flick of their finger.Huaxia Martial Arts Grandmaster Chu Ming, equipped with the Sword God System, unexpectedly arrives in this world. He becomes an outer disciple of the Cyan Yang Sect, possessing extraordinary comprehension, photographic memory, and the ability to traverse the Violet Micro universe, dominate starry rivers, and conquer the myriad realms across heavens.

In novels with a stud there is always a Senior Martial Brother like this:

In the early stages of the novel, his innate talent is high, his cultivation is good, his appearance is handsome, and he has an intelligent, cute younger Martial Sister as a fiancée.

In the middle stages of the novel, he is caught unprepared and defeated by a young disciple (the protagonist) in the sect who’s hardly remarkable at all. From then on, he falls from his godly altar and loses his brilliance. Even his young Martial Sister leaves him for someone else.

In the late stages of the novel, he continues to turn dark, going down the Demonic Path and becoming the major villainous boss. However, the protagonist still ruthlessly defeats him and his soul is eternally sealed.

Once Qin Mo opened his eyes, he discovered that he had become this Senior Martial Brother.
