Naruto: Konoha's Kanpu - Chapter 1017: The End of The Immortal Duo

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”.

- Description from Novelupdates

Jiang Yining was transmigrated to a cultivation world and became the master of the Tianyan Sect.

Unfortunately, the sect was broke and he only had three disciples. Just as everything was about to fall even further apart, he received the Golden Finger.

To make it even more interesting, the Golden Finger was an idle cultivation game that Jiang Yining had played in his previous world.

[Welcome back, long-time player. You will inherit your old account that has been idled for a million years.]

From the game, Jiang Yining could receive martial arts, resources, fates, buildings, skills, and even spiritual roots from checking in and completing quests.

He vowed that he would use the rewards to grow his own sect.

In the world of cultivation existed prestigious families, sects, kingdoms, and even celestial sects. Everyone’s goal was to ascend to a celestial being.

However, years later, Jiang Yining and his Tianyan Sect sat on the Long River and looked down at the people still struggling in the celestial realm.

The young man named Kehma who was summoned to another world, and the useless Goddess Laura whose only strong point is having huge breasts.

Gaining a cheat skill that absorbs the abilities of what he eats, he enjoys his new adventurous life eating delicious monsters and playing with the easy to handle Goddess, all while becoming wildly overpowered/peerless in this otherworld fantasy.

My old man pointed to the flower-like woman and said, "Call her mother from now on." He then pointed to a flower-bud-like girl and said, "This is your little sister."
