MMORPG: Divine Monster Transmuter - Chapter 1

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”.

- Description from Novelupdates

This is a rebirth story of a normal girl, Kylie. She was a normal girl, living a normal life. Married and had kids. Nothing outstanding about her, but nothing terrible either. Then she was attacked and left to die.

Her soul screamed in pain at having to leave behind two small children that needed her, yet she couldn't do anything. As she entered eternal darkness ... it took her some time to realise that she was not dead. She was alive, only yet to be born.

And she was a boy.

Living on the streets of Orchard's Reach, Sen never dreamed about becoming a cultivator. He barely even knew what cultivation was, let alone wanted to do it. When fate intervenes, though, he finds himself the disciple of a cultivator. Like all who find themselves on the path to defying the heavens, Sen will have to decide what kind of person he wants to be and what kind of mark he wants to leave on the world.
