One Piece: The Soul Purchasing Pirate - Chapter 61

That day, the breath of the great whale dispersed the fog, and a new era arrived.Chen Qi accidentally transmigrated into the steampunk-apocalyptic game world of 'New Sun,' starting with the monstrous talent “Deep Sea Affinity,” where ancient deep-sea creatures saw him as one of their own.Although he possessed the talents of a monster, as a transmigrator, he still maintained the original intentions of humanity, striving to level up with the firm resolve to become a world-renowned Monster Hunter.Finally, after his relentless efforts, the popular Dove Times sharply commented:“From the ancient deep sea, a scoundrel with evil bloodlines who threatens witches with tentacles, the arrogant lone Emperor of the Fifth, who aims to conquer the Witch Sea!”False news, blatant false news!Even though he grew tentacles, threatened witches, raised sea dragons, collected tolls, and sang the death chorus with sea monsters.He was truly not of any Deep Sea Ancient God's bloodline but a dedicated and responsible Hunter.Chen Qi cut down the fleet before him and earnestly clarified.

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”.

“Zhong Nuannuan, your charges have been withdrawn. The courts have declared you innocent and pronounced you not guilty for murder. You can leave prison now. Your family is waiting for you in the waiting room outside.” Zhong Nuannuan was startled. She pushed the female prison guard to the side and ran toward the waiting room. She did not even bother to put on her shoes. If not for the icy feeling she felt at every step of the way reminding her that this was not a dream, Zhong Nuannuan would not have believed that she had resurrected.
As she burst through the doors and saw him again, she knew in her heart, that this time she would get it right. This time she would cherish him properly and hopefully, just hopefully, turn her own fate around.
