Among the five paranoid male protagonists, who do you want me to choose?

A sudden journey through time, Yu Zhao finds herself locked in a desperate battle for survival in the Ten Thousand Demon Caves, ready to re-start. Finally returning to the human world, she finds her parents unloved and her brother doting on her adopted daughter. She's been stranded for ten years, starving and freezing. Without the sword bone her master gave her, she would have been utterly destroyed. After escaping, Yu Zhao encounters the protagonist of a suave novel, a pure-hate warrior who seeks revenge after his master dug out his sword bone. The two are a bitter enemy, each with a grudge against the other. One day, Yu Zhao discovers his secret! This guy is the reincarnation of a sword immortal, a backstabbing scoundrel who sharpens his sword out of sight, seeking to undo the regrets of a past life. Her childhood sweetheart, the little demon shark, is actually the Demon Lord of the Demon God Ruins, even the one she casually worships...
