Sword Among Us - Chapter 22: Mini Storyline

A former sporting rifle shooter genius transforms into the ‘Juvenile Butcher’. While originally supposed to have received the death penalty, he was instead fortunate enough to have entered a secret and highly regarded armed force, throwing himself into the ‘Nirvana Project’.

The consciousness of a Great Magus suddenly returned to his original body on earth, just before he transmigrated into the magic world.

Nothing has changed, it's still the same earth.

However, when he looked at earth once more as a former great magus, he discovered earth was not as simple as he knew it to be.

Hidden magus, legendary races such as vampires and werewolves, they do exist, ruling the world through the shadows.

Faced with a former great magus, who possessed as many spells as libraries, would the earth that had been ruled by a few people be able to remain calm?

Qingyun was probably the only villain who suffered this much.

For hundreds of years, a protagonist has always been barking at him and attempting to harm him, but just couldn’t kill him.

When he spent his days bedridden like a dying man, his life was no better than that of the dead.

People respected him, feared him, secretly cursed at him, but he just wouldn’t die!

But he, the ultimate BOSS, has become an insignificant cannon fodder only to be manipulated and destroyed?

That’ll never happen.

A certain green-eyed man: Cutie, come into my arms.

Qingyun: Heh heh, Lao Zi will teach you how to behave.

*Ding* the world’s most ferocious little cutie has come online~
