After Reincarnating, the Ice-Cold Prince Won't Leave Me Alone - Chapter 404: exchange

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.

Cen Shuang used to be the daughter of a wealthy family. After she fell from grace, she was forced to bend her back just to make sure she had enough food. She was sold by her uncle for 10 million to the wealthy Zhuang family as the bride that would counter the bad luck in the Zhuang family.

She married Young Master Zhuang, who went into a comatose after a car accident. Everyone viewed the marriage between the fallen daughter of a once rich family and the comatose young master as ridiculous.

Zhuang Hong, “Nothing about my wife concerns you!” From necessities to food and accommodation, the man did everything himself and spoilt Cen Shuang to the extremes.
