“Hello, have you ever been in a relationship?”“Of course not.” Tenkuji Yuu shook his head, “I genuinely have never had a girlfriend. If you don’t believe me, ask my system. If anyone has memories of being my girlfriend, I’ll admit defeat, okay?”“Then who are they...?”Yuu turned and saw Yukinoshita Haruno, Yuuki Asuna, Natsukawa Masuzu, Yukinoshita Yukino, and Kasumigaoka Utaha walking towards him, with expressions as if they were ready to confront him.“Yuu-chan, I’ve remembered you just abandoning me at the hotel.”“Yuu-kun, I told you, I won’t forget, I will definitely remember you, and I definitely won’t forgive you!”“Yuu, boyfriends can be ‘Ora Ora’-ed for three pages... are you ready?”“Tenkuji-kun, as long as we haven’t broken up, you and I are still a couple.”“Heroine with amnesia, hero leaves... I don’t like these old-fashioned, stomach-churning plots, Yuu-kun.”“...You guys are weird.”Yuu maintained a calm expression, but inwardly he was panicking and getting ready to run.“System, get out here and explain this to me!”System: [Meow]Author: A Passing Chūnibyō Youth

Now, traveling a continent where strength is law and gods play with mortals like pieces on a board.Leo faces a simple question: how strong can you become when dying just makes you harder to kill?

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.
