Library of Heaven's Path 2: Eternal Fate of the Heavens - Chapter 446 - 81: Peak of Galaxy 9-dan

Kenichi Yamada was a 35-year-old salaryman. As a hardcore game enthusiast, he was saddened by the modern trend towards casual games.

So, when a site claimed to be “for people who like to do things the hard way,” he just couldn’t resist. Thus, he was reincarnated into another world as Allen, playing on Hell Mode.

This is fantasy light novel about Allen’s journey as a summoner.

Reincarnated as a serf, he starts from nothing.

His journey begins with absolutely no knowledge of the world around him, just like those games he played 10, 20 years ago.

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”.
