Naruto System in One Piece - Chapter 507

It’s the 3rd of March of the Immortal Martial era.Under the Sect Leader’s unremitting efforts, the Qingyun Dao Sect finally welcomes its eighth disciple, Ye Ping.In order to make Ye Ping stay and to earn his respect, everyone in the sect resorts to all sorts of tricks to deceive him.They boast and pretend to be peerless Sword Dao experts, geniuses in cultivation, alchemy, refinement, divination, alchemy arrays, treasure appraising, and sons of destiny.For the sake of maintaining the image of geniuses, they teach Ye Ping all sorts of nonsensical things.They make Ye Ping try to gain an epiphany out of a random sword mark.They take out a random big pot and make Ye Ping refine supreme-grade pills with it.They take out a random copper coin and make Ye Ping deduce the ultimate heavenly secret.They initially hope to just delay the time that Ye Ping discovers the truth so that he would stay in the sect for a while longer.However, to their surprise, their new little Junior Brother… manages to learn everything.

This is a bizarre and mysterious world filled with various sinister cultivation methods. Once a person begins to cultivate, they will either undergo mild changes in appearance and temperament, descend into madness, or become a great elixir for evil beings to consume...Duan Yun, having transmigrated into this world, unexpectedly comes across a supreme elixir cultivation manual, the 'True Explanation of the Jade Sword.'To his surprise, he is a one-in-a-million cultivation genius who, unwittingly, transforms the manual into something extraordinary. Guided by the Jade Sword, he is able to pierce through everything.Later, as his mastery over various methods grows, Duan Yun, carrying the philosophy of 'the enlightened benefit the world,' never keeps secrets and spreads martial arts across the land.Who would have thought...“Duan the Demon misled me! He said this technique enhances yin and yang, but now I can only squat to pee, boo hoo...”“It was the Demon who taught me this 'Seven Parts Returning Qi'. Instead of blessing me, it brought disaster—I either get killed or step in dung. The fortune-teller said I've lost seventy percent of my luck.”“Don't trust a word of what Demon Duan says! The fairy of the Myriad Wonders Palace was supposed to ascend the whole palace to the heavens, but in one night, she was possessed and turned into a demoness, all due to that old demon Duan's handiwork!”...Duan Yun finds this incomprehensible. All he did was practice martial arts, spread techniques, and occasionally emulate the laws of nature, so how did he become notorious as a demon?This is slander!The same techniques cause no issues for me, so the problem lies with you all, not me!

Traveling through the world of Naruto, he is just a four-year-old boy who has no talent, no family, no blood, and no tailed beast.

Unexpectedly, after completing the Jain test, the system suddenly awakened.

Since then, he has drawn the glittering fruit, the shaking fruit, the dragon-killing magic crystal of fire, the magic eye of death, Geass, the blood of the ancestor giant, the eye of reincarnation, the eternal kaleidoscope writing wheel eye…
