Every One of These Is a Forbidden Art, Yet You Make Evil Look Righteous!

[Transmigration, a System, no female lead, no cultivation in the later arcs.]

Xiao Yihan accidentally transmigrates to another world and takes over the body of someone with the same name. He also successfully activates a System.

But what on earth is this System? Every ability it gives him is a forbidden technique!

The Forbidden Art of Shifting Forms can mimic anyone's build and appearance.

The Forbidden Art of Weaving Illusions can pull people into an illusory world.

The Forbidden Art of Insect Control makes him the king of all insects, with every bug beneath his command.

The Forbidden Art of Summoning Calamity, the Forbidden Art of Refining Ferocious Beasts...

As one forbidden technique after another appears, Xiao Yihan is left completely numb.

The original owner was betrayed by his girlfriend and eventually pushed off a cliff to his death?

No problem. Xiao Yihan will avenge him!

To build up prestige as quickly as possible, Xiao Yihan sets his sights on the scum of society.

A young man who bullies college girls, an office worker with a violent streak, a killer who preys on people on rainy nights...

As one case after another comes to light, Xiao Yihan's name rises to prominence.

Some call him a rat in the sewers. Others say he's a judge lurking in the dark.

Xiao Yihan has nothing but contempt for being called the Dark Asura.

Since when has there ever been an Asura as upright as him?
