Reyhan Alther died at the age of 20 and was reincarnated… as the wind. Formless and directionless, he drifted through a new world filled with wonder and cruelty. But from that breeze, everything began. With a mysterious power called the Divine Spirit System, Reyhan slowly rose—guiding spirits, gathering followers, and changing the course of the world. From a lonely gust, he became a figure known as Father… even to the gods.A battle of fate awaits. But before that, there's still time for the wind to whisper… and maybe crack a small joke or two.

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.
