In regards to the MMORPG Cross Reverie, Sakamoto Takuma boasted an overwhelming strength that was enough for him to be called the Demon King by the other players. One day, he gets summoned to another world with his appearance in the game. There, there are two people that insist “I am the real summon master.” Takuma gets slave-turning magic used for summoned beasts cast on him by the girls –

Igor had asked him to die for the world. She would ask him to die for her. Problem was, he didn't really like dying, not for a second time, at least.

“She's back, let's get a divorce.”After three years of secret marriage, he suggested divorce when she faced a family's crisis and was pregnant. He also turned a blind eye to her plea for help. Disappointed, she concealed her pregnancy and signed for divorce.She thought they would be strangers after the divorce, but her pregnancy was suddenly exposed.When he proposed remarriage, she angrily said, “I only want to keep the child with me, and if you want to see them, kneel down!”She thought he would give up when faced with difficulties, but she really underestimated his abilities.Soon, a video of him kneeling and begging for reconciliation was displayed throughout the day on the outdoor big screen in the most prosperous area of the city.

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”.
