SpiderGwen: I have a system?! - Chapter 135 - : The Marvel Universe

Luan Hualie is just too pitiful! She was just playing a game when she was suddenly transported into another world to become the Young Miss. Just this is okay, but she actually doesn’t have the slightest bit of power!

However, at this moment she had long stopped being the originally powerless eldest young miss. Mythical weapons and pets in her hand, what is there to fear underneath the heavens?

She rose above the mountains and brought down the oceans, and even more so subdued great amounts of devil beasts and holy beasts!

When she swept away the entire continent with her powerful and imposing manner, who could tell she was originally that ridiculous eldest young miss of Lu Family?

He, the prince of Qin, a black-bellied little shotacon, played the pig to eat the tiger. In the midst of the collisions and crossing of swords, how did his mind and body fall into enemy hands?

He, the spawn of the devil, slaughtered and felled the whole world. Without heart, without emotion, without desire. A long contest, countless fights. Why did a brilliant ray of light start to penetrate that frozen world of his?

He, the beautiful man saved from the slave market, obviously had excellent martial arts. Yet, how was he reduced to the most inferior slave? Faced with her salvation, why were his thoughts in a whirl?

And there was still him!

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.
