World Development System - Chapter 311: 242. This Father in Law of mine is a thorough scammer.

After being abandoned by her long time boyfriend on their wedding day, Rachael lost all her faith in love and relationships. But that changed when she met Andrew again.

With no hope of finding love again in her life, Rachael agreed to marry her father's best friend's son, Andrew Collins. But little did she know fate had different plans for her.

…..

Excerpt:

Holding his drunk wife in his arms, Andrew kicked the bedroom door open.

When he placed her in the bed, Rachael slowly opened her eyes. “Are we home?”

“Yes.” Taking her heels off, he covered her with the quilt. “I'll get you some warm water.” But before he could get up, she grabbed his hand.

“What happened? Do you want something else?”

Kicking the quilt off, she crawled in his lap. Placing one hand on his cheek and the other at the back of his neck, she inched closer. “Andrew—”

“Hmm?”

“I think I am falling for you, what should I do?”

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”.
