A man reborn, more interested in his next meal than clan politics, finds himself caught in a power play that could reshape Konoha.Uchiha Masashi has seen it all before - literally. With memories of his past lives and abilities that shouldn't be possible, he'd rather perfect his combat skills than deal with clan drama.But when the newly appointed Fourth Hokage shows up with a proposal to unleash the Uchiha's power beyond their traditional police role, even Masashi has to pay attention. The clan sees opportunity. The village sees profit. Masashi sees the threads of fate that once led to his clan's destruction starting to weave again.As the Uchiha rush to prove themselves “ten times better than the Hyūga,” Masashi walks a fine line between duty and survival.He knows too much - about the Nine-Tails incident that could destroy his clan's reputation, about young Shisui's tragic destiny, about the wheels already in motion.The question is: will he bother trying to change any of it?After all, in a world where even the strongest must sometimes bend to fate, sometimes the smartest move is to grab some dango and watch it all unfold.

The world had been in chaos for over three hundred years.In the Central Plains, singing and dancing never ceased, foreign tribes sharpened their weapons and fed their horses, Sword Immortals roamed the Martial World, and famed generals quelled unrest in all directions.Five years before the great upheaval, the young Pharmacist Li Guanyi committed murder on a rainy night.At last, he opened his eyes and saw this chaotic human world.Underneath the hooves of horses lay piles of bleached bones – famed generals, beauties, the Martial World, Divine Weapons, commoners, Dharma Forms.Since ancient times, only white bones and yellow sand remained on the fields!Confucian Scholars, crushed beneath iron hooves; Buddhas, swept away by long spears!“I, Daoist Li Guanyi, invite this world to its death!”

[Special Containment Procedures]Calamity neared, and a special Containment Subject known as “Bonfire Company” awoke from its slumber, sending out invitation after invitation to join its ranks—“When The Night comes, there ought to be someone to light a fire, to illuminate in all directions.”At the same time, it also brought forth a prophecy.In the year 2044, at the end of a year, a dark disaster would descend from the heavens.
