Conquering System: Harem With Infinite Rebirths - Chapter 450: Suck It!

In the depths of a newborn universe, a cultivator takes advantage of the abundant energy to refine himself a treasure. But after 14 billion years of refining and quite a few more to go, he decides to entertain himself by releasing countless systems and watching how the creatures of this fledgling universe handle them.

On Earth, a young man, lost and confused about what to do with his life, sits in a park and looks up at the night sky. A shooting star, a wish and a bang. When the boy finally wakes up he hears a sound, "assimilation complete. Launching System. Welcome to the Midnight Inn. Host Designation: The Innkeeper."

“There are no heroes. In life, the monsters win.”

...

In 2106, [Mayhem Online], a fully immersive VRMMO game, was released. Soon, it dominated the world's economy when people could exchange the in-game currency with real-life currency and vice versa.

In the year 2107, Flynn Grey, a 22-year-old college dropout with an ambiguous history, joined in the fray of billions of people that had already started playing [Mayhem]. Hoping to uncover the game's secret and earn a fortune, he spent months on adventures without fruitful results.

For better or worse, Shura, Flynn's in-game character, ends up in a great Wyvern's den, acquiring a hidden class and a monstrous race. Join him as he defeats his past and paves his way into becoming a true legend in both worlds.

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.
