The Dread of Damned - Chapter 22: Heart Blood 2

“Blue Star 4.0 will begin its maintenance-free update at 12:00 AM on April 1st. The main content and adjustments of this update are as follows.” “New monthly rule ’Active Talent’ added: All players must converse with others for a total of 1000 sentences every day...” When an abrupt notification sound echoed in the ears of all humans on Blue Star. The world faced its cleansing. In every monthly version update, a new rule would descend, which all players had to obey. ... Chen Yi, who had found a massive loophole before the third version update, looked at the six-figure Points Balance in his account and broke into a grin. “Tuberculosis Rabbit, this time we might just rise to the top.”

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”.
