"Unify the Ninja World," "Chat Group," "Multiverse," "Decisive and Ruthless," "Kushina," "Invincible"

Yu Cheng transmigrated into the body of the young patriarch of the Whirlpool Clan. Faced with the impending extermination of his clan, he dared not stop for a moment!

Fortunately, his three adopted sons were transported to the worlds of One Piece, Demon Slayer, and Martial Soul, respectively.

And so—

"Old Cheng! Is the Dark-Dark Fruit any good? Hehe... I want to use the Impure World Reincarnation~"

"Come here! Old Cheng, I'm now an Imperial Beast. Which soul beast do you want as your summoning beast? I'll teleport you there!"

"Uchiha Madara wants to fight you? And the Otsutsuki want to join the fray?! Fine, let's fight!! Behold my Sun Breathing!!!"

Several years later.

Uzumaki Yu Cheng transformed into the Demon King, wielding the Supreme Great Sword, stepping on the Black Dragon Emperor, his Rinnegan lowered, looking down at the dying Allied Shinobi Forces.

"From this day forward, the ninja world will be unified. And I... will stand high in the heavens, becoming an immortal god!"

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..."

[Peerless Tang Sect] + [Anti-Three Abuse] + [Fatherly Love, Daughterly Filial Piety] + [Aizen] + [Unsung Boss] Shrek City. Heartbroken, Moon and Xuanzi stared intently at Aizen, who stood high in the sky. "Aizen! Turn back now, everything can still be salvaged!" Aizen, rising slowly within the anti-membrane, looked emotionlessly at the suffering Huo Yuhao, Wang Dong, and the elders of the Sea God Pavilion below. "This world is sick—history has been distorted beyond recognition, good and evil are blurred. From this moment on, the so-called empire will be wiped out, the so-called gods will be torn down from the altar, and this window of opportunity for the throne of heaven will also end." With this, Aizen removed the black-framed glasses that concealed his ambition. "From now on, I will stand in the sky."
