MTL - Battle Emperor - Chapter 7 One year of penance

In 2077, the gods sent potential successors across the cosmos to Earth for the God Trial. The result: the apocalypse and the rise of history’s most unlikely Harem God candidate.

Leon Traxler was a sociopath that faked his emotions and had a phobia of using women for sexual desires. Yet he chose the power to build an overpowered harem because finding strong, loyal companions during the apocalypse was unlikely.

It was a calculated decision, but he got something he hadn’t bargained for.

Emotions.

With a power that leveled him up through emotional milestones and a system that made him feel them for members, he quickly amassed power and decided that the apocalypse was a blast.

Driven by a desire to make his violent yanderes happy, a love for animal ears on women, and a narcissistic wet dream to be the only man on earth, he decided to partake in the God Trial.

His strategy? To raise an army of women, build a city for his harem, and start a cultured civilization that would naturally end when he died.

Join Leon as he becomes a celebrity on god social media, rises to power on earth, and lives life as a playboy in the apocalypse.

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.
