The Scum Villain’s Self-Saving System - Chapter 21

In the Province of the Nine Skies, far above the heavens, there exists Nine Galaxies of Astral Rivers made up of countless constellations interwoven together.

For Martial Cultivators, they could form an innate link with one of the constellations, awaken their Astral Soul, and transform into a Stellar Martial Cultivator.

Legend has it that, the strongest cultivators in the Province of the Nine Skies, were beings that could open an astral gate every time they advanced into a new realm. Their talent in cultivation was such that they could even establish innate links with constellations that existed in a layer higher than the Nine Layers of Heavens, eventually transforming into the heaven-defying and earth-shattering power known as the War God of the Nine Heavens.

Qin Wentian is the MC of this story. How could a guy, with a broken set of meridians, successfully cultivate? There were countless Stellar Martial Cultivators, as there were countless constellations in the vast starry skies. What he wanted to be, was the brightest constellation of all, shining dazzlingly in the vast starry skies.

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.
