We… can’t do this!” I jolted back when he pulled up my skirt.As if to retaliate, he grabbed my wrist and yanked my body to his. “We can do whatever I say we can do, María José.”“I’m your brother’s reject. Do you even hear yourself right now? He didn’t want me, Axel. What does that make me to you?”“I don’t care about Álvaro’s foolishness. It's his loss for losing a woman like you.”“Okay, I must confess. I'm not worried about him either. It's Rosa… you're getting engaged to my sister in a month!”“Let me remind you, María José—I don’t give a fuck about that, either.”No matter how hard I jerked, he wasn’t letting me go.

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.
