What if one could defy death and, instead of perishing, be reborn?

Such a situation happened to Kieran Silver after succumbing to his circumstances caused by wicked superiors.

After being reborn, Kieran's desires changed and he considered the many routes.

The route that resonated with him most was Zenith Online, the MMORPG that changed his life initially.

In his past life, he was a bare minimum kind of guy, using the least at its maximum potential. However, his current outlook changed.

Accomplishing the bare minimum? No, he would go above and beyond!

On his path to greatness, creating an immortal legacy that resounds throughout the universe, dethroning his former guild, and other grand feats will become his stepping stones.

To ensure his aspirations become reality, Kieran must walk a path where he becomes an entity prime for destruction.

Magic, destruction, and ancient practices are just a few of the factors that mold his ultimate power. What began as one of the Hidden Classes would ultimately evolve into a one-of-a-kind entity!

The ultimate power isn't given or born, it is manifested.

“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.

Before going to college, an ordinary high school student went to celebrate and got drunk. When he woke up, he found himself in a completely different world. There was a big sect, the approaching sect entrance examination, a slum where his body’s previous owner lived, and a shared memory about a missing young girl.

When he got tangled in a fight with a few punks in this different world, he fell off a cliff and miraculously found himself still alive, with two more voices ringing inside his head. They were Sword Master and Saber Master. In the company of them, he continued to find out more about this whole new world. He took the sect entrance examination, entered the sect, met a strange man in black, and even participated in a major competition of the sect to have a chance to win over his peers!
In this whole new world, he was born again and got to explore the fantastic martial world!
