Like a ride on the Logan Everett express.Which, naturally, leads to a whirlwind of its own: She's his fated mate. Because of course she is.And he rejects her. Because of course he does.Now embroiled in a mystery bigger than her post-breakup hangover, Nicole finds herself the prime suspect in a murder she didn't commit—no matter how tempting the thought might have been.

In the end, Jacob chose it anyway with no way of going back, and it was also the start of his suffering and his icky, brutal journey toward the 'Immortality' he wanted so badly!

Nine Tribulation Immortal Emperor, reborn in the city!One Earth, one Immortal Realm, the difference is as vast as that between heaven and earth!

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.
