Tang San's Twin Sister - Chapter 61

“Look Left.”Pierre, a professional cynic and amateur MMA fighter, dies in a hilariously ironic argument with the author of a garbage-tier webnovel. His final complaint? The pathetic hero gets stronger by touching women's chests.As a reward for his “passionate feedback,” a bored god reincarnates him into that very world.Now, trapped in a story he loathes, Pierre is given a gift: a leveling system and a power far darker than the hero's “Boobie Boost.” His is called Essence Drain: a parasitic ability to steal power through physical contact, an intimate violation that feels dangerously good.The hero of this world can have the plot armor and the clichés. Pierre will use his intellect, his brutal new power, and his insider knowledge to hijack the story. His first move? Steal the hero's fated beautiful navigator before they can even meet.They call him a menace. A criminal. A terrorist. Fine. If fighting a world run by corrupt Marines and preening nobles makes him a villain...He'll become the greatest villain the world has ever seen.-----------Additional tags:No Incest, No Rape, No Yuri, Harem, No Loli, One Piece, Transmigration, Pirate, Pirates, Princess, Shonen, No NTR

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.
