In a world where magic was abundant and supernatural creatures existed, Jin Valter lived as a fallen genius. Being the son of two A-Ranked Hunters, Jin had inherited his father’s keen eye for martial arts and his mother’s innate talent for magic. Alas, before Jin could reach his full potential, an Outer Demon attack left his soul crippled and his body weakened beyond repair.

Now, Jin lives out his days bound to the hospital bed with nothing but his brains to keep him company. Gone were the days when his peers hailed him as a genius as he struggled to even conjure a spell with his body falling apart.

However, it would all change when on the Night of the Blood Moon, a unique visitor paid him a visit…

In the year 2090, technology has advanced to the point where Simulation Boxes, (Sim Box for short) are common place, allowing for the user to link up their brain's neural network to a full dive Simulation. While initially used for educational purposes, recently a large gaming company, Averon, released a fully fledged immersive MMORPG simulation where users can become anyone they desire, level up, choose their class, and become a hero or a villain. The name of this simulation is The Shattered World Online.

Eli Winters had no interest in playing it. His father, a jobless bum who spent his entire life playing games in the hope of becoming a famous player or streamer, was able to use the release of The Shattered World Online to gain wealth and fame, quickly becoming the number one player and a household name as the game took the world by storm. He immediately abandoned Eli and his mother in favor of being with someone from his guild, despite his mother having worked two jobs to support them and raise Eli by herself. Eli had nothing but spite for his father and the game.

When Eli's best friend convinces him to try out the game, his father's fame begins to interfere, culminating in him being singled out and shunned by his peers, and his father offering to pay for his university tuition in return for Eli hiding their relationship and quitting the game. Instead of complying with his father's wishes, Eli decides to prove to everyone how useless a guy his father is by challenging him that if Eli is able to surpass him in the game world he must delete his account and quit his streaming career. His father accepts the challenge believing his son to be useless at games - but Eli will soon show him just how ambitious a spiteful person can be.

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”.
