Naruto: In the Mist, It's Reasonable to Have a Mizukage Warm My Bed

Transmigrating into the Village of the Bloody Mist, Kan Minazuki opens his eyes in an ANBU death-row cell. Awaiting him is the butcher's blade of a great purge.

At the brink of death, he awakens the Imperial Procreation System! By uniting with female ninja who possess kekkei genkai, he can extract their genes, make his Ice Release evolve without limit, and unlock god-tier secret techniques! "Below absolute zero, even space-time and causality will freeze."

He pierces the Fourth Mizukage's heart with frozen chains and draws Mei Terumi into his embrace. He snatches away Pakura, wielder of Scorch Release, fusing ice and fire to command the extremes of heat and cold.

From an isolated island shrouded in bloody mist to an empire of ice and snow spanning the shinobi world, he freezes Madara Uchiha's meteorites with a single thought and drags the gods of the Otsutsuki down from their divine pedestals.

When the Infinite Tsukuyomi descends, Kan sits upon his frozen throne and gazes down coldly. "In this shinobi world, I alone decide who lives and who dies!"
