MTL - The Big Brother’s Daughter Has Become the Favorite of the Wealthy Group - Chapter 52 I seem to have seen the doorkeeper's guinea pig again

Noir, third son of a “beggar noble,” lost his job and was at a loss, but fortune struck just as he was contemplating becoming an adventurer.

I became a scientist for an evil organization.…But I’m too competent.

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.
