King of Kung Fu in School - Chapter 499 William Made a Pass at Her

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.

Upon traversing through time, Divine Doctor Qi Yu became a foolish Princess, the kind doomed to be entombed alongside her husband. Fortunately, her medical skills were exceptional. With a unique secret technique, she fished a certain Prince out of his coffin and performed a spectacle of raising the “dead.”Everyone said that after dying once, the Qi Family's useless Second Miss seemed to have transformed into someone else. Not only did she punch pure lotuses and kick duplicitous teas, but she also possessed the Resurrection Technique and mastered all sorts of martial arts, turning the entire capital city upside down.All the civil and military officials of the court begged the Prince to divorce his wife, yet the Prince, with an expressionless face, retorted, “The one spoiled by this Prince, if you can't stand it, just suck it up.”

An Hao leaped, thinking she had died, but to her surprise, when she opened her eyes, she found herself back in the year 1985. To live a second life, did she have to endure the abuse of her stepmother and stepsister again, the dislike of her mother-in-law and disdain from her sister-in-law, and the betrayal of her best friend who bravely became the other woman just to slap her in the face and climb the social ladder? Was she supposed to end her miserable life in poverty again? An Hao's answer was, “Eat! Shit! No!” She was determined to make something of herself, to get rich by capitalizing on her knowledge and aim for a well-off life. This time around, she was going to be the protective big sister who reformed her worthless little brother who had died a wretched death, and the virtuous wife to make up for her past neglect of her husband! She wouldn't let this life go to waste in despair! A malicious best friend? Coveting her man? Not a chance! Go hang out wherever it's cool! Cough cough, how did she not realize in her past life that this “Stoic King of Hell” was so indecent. Decent? You've had your fill of decency during the day.

Despite being the ruler of a nation, nobody was willing to marry the vicious man with a bloodlust.
