Armed with future lore knowledge; full potential in Magic, Combat and Voice; Overpowered Parents and a Cat; the Nord kid will set out from Riften to find himself becoming a Hero way before the start of the game events.

Everyone said that Yi Qing was the number one Sword Cultivator in the world, with a swordsmanship and cultivation that no one could surpass. Whether it was when he was cultivating in the Lower Realm, or when he was in the Ten Heavens of the Upper Realm, he has always been undefeated.

Yi Qing laughed and said: “That is because you do not know of my Master. If we speak of cultivation, I am not as good as she by a long mile. Thinking about it, at the start, out of the ten Heavenly Emperors of the Upper Realm, my Master beat up nine, and the one left was myself.”

“Master? You actually have a Master! Who? How come we never heard of it?”

“My Master is…. Eh? Master? Master! And my Master? Has anyone seen my Master?”

A person next to them quietly raised her paw. “I am here!”

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.
