Infinite Mana Exorcist - Chapter 18: Guild

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

Kai was a 17-year-old dropout. A NEET. A background character in real life with nothing to his name but bitterness, novels, and guilt. After his parents died, he gave up on the world. People were fake. Dreams were pointless. And that one novel he kept reading? He hated it especially the main character, June. Perfect, noble, always standing tall. Everything Kai wasn’t.Then, one night, a voice asked: “What if you did meet June?”He said yes, half-asleep and half-mocking.Now he’s trapped in the novel. Isikeid. But he’s not June. He’s not a hero. He’s not even in the main cast.He’s an extra in the background of a world he knows too well and he’s had enough of watching things play out the same way. This time, he’s going to change everything. Whether the world likes it or not.

Lin Xuan transmigrated into a world where demon beasts rampaged. He became one of the lowest ranking wasteland reclaimers in the Germinal Organization to explore the mystic realms.

The Zero Realm mystic realm was the Giant Rock Cave. The First Realm mystic realm was the Demon Ant Nest. The Second Realm mystic realm was the Tree King Sea.

Lin Xuan’s eyes were wide open. He was well-versed in how this worked. This was similar to the AFK games that he played in his previous world.

As such, he began his comfortable journey of becoming the strongest.

Up until one point, the Germinal Organization discovered that he was abnormal and decided to deal with him. It only then did Lin Xuan realize that even Seventh Realm fighters and the managers of the organization were inferior to him.
