Overrun by monsters, humanity was on the brink of extinction. But at its darkest hour, something miraculous happened—those who died returned, awakening strange new powers that allowed them to fight back.Vale knew that story well. Maybe that's why he wasn't surprised when he heard the voice of the system speak to him.[ Congratulations! You have died. ][ Your First Trial of Death begins now. ]What truly shocked him, however, was the question burning in his mind:“Who would dare to assassinate the Second Prince of Verythmia?”

«Farming wives in the apocalypse.» Getting a wife is possible. Getting Wives is hard. And in the apocalypse, it’s impossible. But what if you have superpowers that allow you to do anything? I mean everything!

Shaojin’s piercing gaze lingers on An Yin, his brother’s “girlfriend,” as she trembles under his scrutiny.

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”.
