The Scum Villain’s Self-Saving System - Chapter 52

In the year 2057, the world has become a corporate-run utopia for the super-rich, and a hellhole for all the rest.

Catherine 'Cat' Leblanc is an orphan that is about as far from super-rich as one can be. When the Incursion alarms start blaring and the sky starts raining hungry xenos, it's just another blemish on an already piss-poor afternoon.

A cyberpunk magical-girl alien-invasion LitRPG.

It’s exactly as wild as it sounds.

Five years ago, Gu Qiqi’s best friend’s boyfriend cheated on her. She helped arrest someone, but she caught her fiancé. When she left, she was dragged into the room by a mysterious person…

Five years later, Gu Qiqi married Yan Haocheng, who had some problems in city A, with twins whose father was unknown. Everyone felt that Gu Qiqi must have married Yan Haocheng by virtue of his “special ability”.

But she didn’t know that it was Yan Haocheng who didn’t want to marry her. She was afraid that he would die alone, so she gave up and married.

Other people’s impression of Yan Haocheng is: cold, scary, and without desires.

Gu Qiqi’s impression of Yan Haocheng is: shameless, shameless, humanoid teddy.

Others rely on beauty to attract men, but Gu Qiqi only needs to wink at the child to turn her man into a puppy.

In this world, orphans or just anyone without any hope for this world can apply to become a “walking target”. Their sole purpose is to be a practicing dummy for the students of the sect who train to become “Demon Hunters”. These students need “walking targets” to test their training on living, walking beings of flesh and blood.
In exchange, they will be provided with food & shelter.
Their existence value is lower than a slave, but if they manage to survive a few years they can receive a life long pension.

Xiao Han is such a “walking target”. One time he witnessed a powerful Demon Hunter disposing a demon. When the demon died, a fragment of the demon that managed to escape entered Xiao Han’s heart. No one saw that, and even Xiao Han himself only felt some discomfort for an instant.

But that thing in his heart soon gave Xiao Han visions, and the first one is of a cultivation method which allows Xiao Han to absorb damage to enhance his body. A perfect cultivation method for a “walking target”.
