After being struck by lightning and transported to the world of One Piece, Lin Hai merged with the Rainbow Mist, with one part being absorbed into his body and the other drifting away with the wind.

Lin Hai, who had planned to live a peaceful life, never expected that his body would become uncontrollable and allow him to travel to other worlds. Being too weak and too afraid to go alone, he had no choice but to join the Straw Hat crew, whom he could trust, for a world adventure.

What he didn't know was that each time they traveled through time, another rainbow mist would open, bringing people or things from other worlds into the world of One Piece.

What kind of future will these changes create...? Let's wait and see!

Starting from chapter 332, you can return to the worlds you visited together!

These days, without a system, even your life isn't guaranteed when you transmigrate. Fortunately, while there's no system, there's a cheat code… Ye Yu has transmigrated to countless worlds simultaneously, able to share and feedback his power with others. In the Naruto world, he faced Six Paths Madara head-on, with five thunder dragons roaring to the sky behind him. In the One Piece world, he escaped from Impel Down and shocked the world at Marineford. In the Bleach world, he ascended the throne of Heaven before Aizen. In the A Certain Magical Index world, he's a legend in Academy City, hailed as the man most likely to become a Level 6 esper. In the Detective Conan world, he possesses special abilities and is a guest of honor for many conglomerates. In other worlds, he's also a pinnacle of existence… In all these worlds, Ye Yu humbly stated that without the “strong support” of his colleagues, he would have been in a difficult situation. What…

Lu Gang suffered an accident during his transmigration, his soul was copied into ninety-nine parts, and he was transported to different worlds! His memory and talent were shared! Lu Gang, a cannon fodder war god who was besieged by a level-three rat horde at the start, thought it was the beginning of his rise, but then everyone else died! [Naruto Lu Gang]: Starting as an Uchiha, you try fighting Itachi. [Covering the Sky Lu Gang]: A mortal body undergoing heavenly tribulation, you come and you'll fall too. [Warhammer Lu Gang]: Four-armed emperor above, this must be Tzeentch's conspiracy. [Curse of the Law Lu Gang]: Transmigrated into Shunping, what can I do if I'm being targeted by a real person at the start? [One Person Lu Gang]: Started by becoming sworn brothers with Wugensheng, what's the use of me saying I'm not familiar with him? [Goblin Lu Gang]: Aba aba aba... Facing countless Lu Gangs staring at him, [Devouring Lu Gang] was on the verge of tears! Fortunately, Lu Gang could enter other...

Tianji transmigrated to the world of Bleach. Knowing Bleach well, he originally thought he could make a name for himself, but fate played a joke on him. Tianji transmigrated to 1,500 years before the main storyline. At this time, there was no Shinigami Academy, and even the Gotei 13 had not yet been formed. The only one protecting the Soul King was the Zero Division, which only had two members.

That's not all. I thought I could finally enjoy life after defeating the Grim Reaper, but then I was transported to another world.

Uchiha Shimei has transmigrated.

The good news is that he transmigrated into the Uchiha clan; the bad news is that the system has a bug, insisting that he is Hashirama Senju.

[Ding! Detected that Lord Hashirama has appeared among the Uchiha clan. Lord Hashirama, please show your hospitality as Hokage and shake hands with 10 Uchiha clan members!]

[Mission Reward: Unmarked Healing!]

[Ding! Detected. Huh? Hashirama-sama has awakened the Sharingan? Looks like it's his younger brother Tobirama's doing. Mission issued: Correct Itachi Uchiha's misconceptions!]

[Mission Reward: Mangekyou Sharingan!]

During the Third Shinobi World War, looking at Uchiha Shinobu, who was even more skilled in using Wood Release than himself, Senju Hashirama fell silent: "Damn it, I feel like he's more like Senju Hashirama than I am!"

Naruto Uzumaki, who suffered bullying from the villagers since childhood, always longed for friends. Until one year, a training system bound itself to him, telling him, "Only the strong deserve friendship. Train hard, Naruto, and you will have many friends." Half-believing, half-doubting, Naruto began his training journey. Later, "Naruto, will you be my friend?" On the ground, a bruised and battered Sasuke Uchiha asked Naruto in humiliation. Hearing this, Naruto loosened his fist, warmly helped Sasuke up, and smiled slightly...

"Awakened the incredibly powerful genjutsu Kotoamatsukami, and then just died like that? Uchiha Shisui, do you even know how to play games?" "They just decided to rebel, and then they surrendered after seeing their son slaughter the entire clan. Uchiha Fugaku, are you kidding me, clan leader?!" "And Uchiha Itachi, your son... well, mentally ill people can kill without consequence. You're mentally ill, so what!" Having transmigrated into the Uchiha clan, right after the Nine-Tails' attack, Uchiha Shuichi felt a bit overwhelmed. He searched for his cheat ability for ages, only to be told it couldn't be used for ten years. But he did the math: at most seven years, and the Uchiha clan would be wiped out. "Whatever, the Third Hokage could fool Uchiha Shisui and Uchiha Itachi, I can still play the role of the Fire Intent..."

He transmigrated to Konoha Village, becoming a cannon fodder genin. The Second Shinobi World War raged on, and Natsume's ninjutsu consisted only of the D-rank Three Body Technique and the C-rank Earth Release: Wall. His superiors were utterly inhumane, always using him as cannon fodder, forcing him to narrowly escape death on almost every mission. Natsume felt he could die at any moment. Fortunately, the "Good Boss System" activated. By sacrificing his direct superior or seizing their position, he could gain a chance to win rewards. Sacrificing a Chunin captain granted him the Kagura Mind's Eye. Sacrificing a Special Jonin captain granted him a Jonin-level chakra. ...When the death rate of Natsume's direct superiors became extremely high, he finally faced questioning from Konoha's higher-ups, "Natsume, we need you to explain why your superiors' casualty rate is so high?" "Because they deeply understood the Third Hokage's..."

He was transported to the Naruto world by accident and discovered that he had gained the ability to absorb energy. So he went further and further down the path of searching for and absorbing others.

He absorbed Uchiha Shisui's corpse, gaining some chakra and some ocular power, and acquired the Mangekyou Sharingan, Kotoamatsukami!

Absorb Hashirama's cells to gain a large amount of chakra, and unlock the Wood Release bloodline limit!

He absorbed Naruto's blood and gained the Uzumaki physique and Ashura Chakra!

When he absorbed everything and achieved the title of strongest, the ninja world finally ushered in true peace.
