MTL - Chongfei Manual - Chapter 163

When Ryujin wakes up in the video game he use to play, Espers of the World, he quickly realizes something terrifying: this isn’t a game anymore—it’s reality.Stripped of his identity and renamed Kaidren, he must now survive as a low-profile orphan with a mysterious past and a future controlled only by power. The world around him mirrors the game’s setting, yet the rules are no longer bound by code. The television works. The phone updates in real time. Events that never occurred in the original storyline unfold before his eyes.The NPCs? They’re real people now—with real emotions, real consequences, and real power.As Kaidren struggles to adapt, he’s haunted by memories of a trauma-stricken life and an overwhelming detachment from emotion.But the deeper he explores this so-called game world, the clearer it becomes—this reality is unpredictable, unscripted, and far more dangerous than he ever imagined. And to stay alive, he’ll have to confront what it means to be human... and what it means to be powerful.Because in this world, the line between player and pawn no longer exists.

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.
