Naruto: The Strongest Kakashi - Chapter 417 - Swords Fight

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”.

The beautiful Blue Star tragically fell victim to an invasion by enemies from the Otherworld. The globe was left riddled with wounds, but it also presented an opportunity for the Awakening of the Blue Star people—a chance to choose something other than hot weapons. Individuals could use their own strength to slay enemies, amass wealth, and reach the pinnacle of their lives.Ye Nai was lucky enough to awaken in advance, releasing energy spores that could decompose organic matter. He had planned to make a stunning debut during the mass Awakening at school, but results showed he hadn't awakened?!What the hell?I haven't awakened?Then what's this Fungal Mycelium I have that can decompose abnormal creatures?Ye Nai gave a devilish smile.Haha, everything that happens is to my advantage. Whether it's the enemy or abnormal creatures, obediently fall into my hands and become nourishment for my mycelium!
