An unexpected event transports a young Chinese man to the world of Tokyo Ghoul, making him Kaneki Ken's older brother. Awakening a system, his purpose isn't to complete its tasks, but to change each world, shaping it into the world he desires. —————————— First World: Tokyo Ghoul Second World: Tentatively Titled: Demon Slayer

[Multiple female leads + semi-invincible + slow-burn, hoarding type + rejects bloodline dependence]

When Gu Yuan woke up, he found himself transported to the Naruto world. Due to a traitor's betrayal, he was now the only surviving member of his family. Fortunately, his parents and his senior sister, Kurenai Yuhi, had a close relationship, and Kurenai took him in. She discovered his special ability as a transmigrator—the ability to enumerate all possibilities. As long as he could set variables and conduct practical deductions, he could obtain the desired result.

As he gradually calmed down, he forgot the cruelty of the ninja world. It was only when the night of the Uchiha massacre approached that he realized he was about to lose his friend Uchiha Ryūna. In order to find a way to save her, he overexerted himself and fell into a coma while performing mental deductions. When he woke up, it was too late, and he didn't even get to see her one last time.

Worse still, the overdraft caused problems in his ability-advancing mind lab. Only when he experienced a complex emotional state that resembled both romantic love and familial affection could he utilize his computing power to the fullest extent and complete the unfinished blueprint for the life ninjutsu...

He had no choice but to target his childhood sweethearts, planning one confession after another, but all of them failed due to unforeseen circumstances. Just when he was feeling disheartened, he discovered that the girls actually had quite a few feelings for him...

The world has always been a place of survival of the fittest, and he chose to do his best to pursue his goals, leaving the rest to fate.

Self-defense accessories, tactical units, automated puppets, ninja life forms...

The desire to protect everything pointed him in the right direction, and the fusion of emotions fueled his inspiration, gradually giving him the power to challenge the entire world.

Gu Yuan: To hell with bloodlines and eye transmission! As long as I can set variables, I own the whole world!

Xiao Xuan transmigrated into the Whitebeard Pirates and awakened the dungeon system.

You can get generous rewards as long as you clear the dungeon.

[Imperial Capital Dungeon: Iron-tier dungeon, come...]

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 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!"

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!
