The Vampire Cat System - Chapter 348 Bernard?

Chen Han was a genius and hard-working boy. When he defeated a young master of a prominent family, he was attacked in retaliation. His dantian was shattered and he fell into Jianyuan. He was reshaped by a mysterious entity with the true spirit of his life, and he cultivated the techniques of the Peerless Heart and The Emperor.

With peerless mentality and supreme combat skills, he fought fiercely in the world, swept the six lower realms, and galloped across the three higher realms.

When countless treasures of heaven and earth, divine weapons and sharp weapons are in the bag, when countless beautiful women return to the harem, and when countless strong men are completely annihilated, this vast world would be under my feet!

After facing her fiancé’s betrayal, things take an unexpected turn after Tang Mo’er inadvertently gets involved with the Capital’s preeminent magnate, Gu Mohan.

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.
