Local Netizen Elf's Life In Another World - Case 6: Chess prodigy.

In the game Myth2, Klaus Park was already considered a top player at just 13 years old. With his advanced knowledge of the game and methods of adapting to the most varied situations, he became a world champion younger than anyone else. However, due to a tragic incident, he left his team and the gaming world a year later.

Now, 7 years after leaving the professional scene, he returned to play the eminent VRMMORPG called Rise Online, a unique game of unrestricted freedom whose number of players already exceeds one hundred million. This game allows players to use real-world skills such as martial arts, archery, blacksmithing, or reaction time for their own benefit, along with the freedom to explore 7 colossal, mythological worlds.

Planning how to conquer dungeons? Fight against powerful guilds? Slay the Werewolf King? Face hordes of thousands of zombies? Have the power to revive the dead? Or discover unknown battle techniques?

None of this is impossible for Klaus, a legendary player, and holder of the Psych Class, allowing him to see and talk to spirits, copy abilities, cast magic items, and see the signs that no one else can see across the worlds. His real goal is to reach the throne of the paranormal world and the top of the player and guild ranks of Rise Online. No matter what is in front of him, he will be head-on with his best, be it the High Lord of Vampires or the strongest Guild Master.

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”.
