[No System, Hard-Core Power Fantasy | Possessing and Observing | Reborn to Change Fate | Protecting and Healing His Child | Overpowering the Entire Shinobi World] Hatake Sakumo, Konoha’s White Fang, spent his life protecting Konoha and fighting across the shinobi world, only to be betrayed by his comrades, vilified by the entire village, and driven to take his own life! The world believes he died by suicide out of cowardice, but no one knows that his lingering soul survived his death, clinging to his own White Fang tanto and remaining trapped there for decades!
For decades, he watched from the sidelines, silently witnessing every tragedy and joy in the shinobi world! He saw his young son Kakashi grow up lonely and live half his life in gloom; he watched Obito fall into darkness and Rin die a tragic death; he witnessed the Uchiha Clan Massacre and Konoha’s endless internal strife. He lived through the Battle of the Valley of the End and the ceaseless wars of the shinobi world, seeing all the suffering and injustice in the world!
Having witnessed the shinobi world’s final outcome and carrying decades of memories and boundless regret, he finally defied fate and was reborn on the eve of his suicide! This time, he has no System and no cheat powers. Armed only with peerless strength at his peak, a lifetime of political experience, and an all-seeing perspective on the entire future of the shinobi world, he returns in force to cut off every tragic destiny!
In his previous life, foolish kindness and forbearance left him disgraced, bereft of his family, and consumed by regret at the end. In this life, he lets his sharp edge show and protects his own to the very end! Who dares plot against him or harm him? Danzo, the ambitious schemer, makes one move after another? Sakumo counters and crushes him outright, tears his schemes to pieces, and uproots the cancerous Root organization! The corrupt Konoha High Command is locked in internal power struggles? He forcefully sets things right, restores order, and sweeps away every shadow!
Foreseeing the Uchiha Clan Massacre, he lays his plans early and works behind the scenes to save the clan’s bloodline and end Konoha’s internal strife! When he takes part in the Third Shinobi World War, he overwhelms Hanzo and surpasses the Legendary Sannin, deterring the Five Great Nations single-handedly and restoring the White Fang to unparalleled glory
Write Konoha White Ga as a good politician. The whole article is about the struggle for power and does not focus on improving one's own strength. I came here specifically to search for White Fang, but I regretted abandoning it.
