Naruto System in One Piece - Chapter 114

The path of immortality is nigh unachievable.Furthermore, the immortal world has been completely transformed by a plague!When immortals contact infected mortals, their cultivation bases fall, or worse, they return to the heavens; thus, the immortal and mortal realms have been eternally separated.Moreover, all immortal arts may only have one practitioner; thus, the world of immortality has become a dark forest.…Although Li Fan had grand ambitions when he first transmigrated to this world, he could only be trapped in mediocrity, slowly wasting away his mundane life.Fortunately, as he was dying, he finally awakened a supreme treasure that could turn truth into lie and reality into dream, reversing time to when he first arrived!Following this, Li Fan embarked on his endless path to immortality!In his second life, Li Fan ascended through politics and ruled the world after 50 years, but after searching worldwide, he found no trace of the Immortal Dao. Only at the end of his life could he glimpse the immortal path.In the third life, despite immense efforts and carefully laid schemes, Li Fan ultimately couldn’t resist a single strike of an immortal’s sword!In the fourth life……I, Li Fan, an ordinary mortal, will harbor no regrets throughout a thousand lifetimes, all for the pursuit of immortality!

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”.

[No NTR]

I got pulled into the NTR game I was going to gift to my pure harem lover friend.

The game has already progressed to the middle, and the heroines seem to have been already stolen away from the hero, in which I was transmigrated into.

Now I just deeply crave for a cigarette, but I can’t even smoke in this world…!

One night a mysterious and unexplained phenomenon occurs in the nine provinces. Five years later Chu Feng, a regular outer disciple of the Azure Dragon school, awakens one of the mysterious nine lightning beasts. And discovers an egg sealed inside him.

From there we follow Chu Feng as he crosses the continent, beating up strongest senior brothers, raiding tombs, destroying sects and of course as he conquers beauties.
