If Minato Namikaze hadn't died in Naruto, and if Bibi Dong hadn't entered the secret room in Douluo Continent...

Unexpectedly transported to a time of human crisis, I become a professional dream interpreter...

New author, new book, synopsis is lacking, thank you all for your support.

He transmigrated to the Ultraman world and became Zagi, the Dark Destroyer. Although powerful, Ye Lian was very unhappy because he had been sealed in a dimensional rift by Noah. He was constantly waking up and sleeping, living each day on a tight schedule, and was almost going crazy. Just then, he received an invitation: "Ding! The Dimensional Chat Group invites you to join. Do you agree?" "Known group members: Toad Mountain Good S Sage, Namase Izumi, I'm very curious, Daigo made into soup."

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.

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..."

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!"

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.

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!
