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

Transmigrating into the Bloody Mist Village, Mizutsuki Kō wakes up in a dark prison cell of the ANBU, awaiting the executioner's blade of the Great Purge. At the brink of death, he awakens the [Empire Reproduction System]! By fusing with female ninjas possessing bloodline limits, he can extract genes, allowing his Ice Release to evolve infinitely and derive god-level secret techniques! "Under absolute zero, even time-space and causality will be frozen." He pierces the Fourth Mizukage's heart with ice-forged chains and pulls Terumi Mei into his embrace; he intercepts Pakura of the Scorch Release, blending ice and fire, mastering extreme cold and heat. From a blood-soaked isolated island to a snow empire spanning the ninja world, Madara Uchiha's meteor is frozen by his will, and the Ōtsutsuki gods are dethroned. When the Infinite Tsukuyomi descends, Kō sits on his frozen throne, looking down coldly: "In this ninja world, only I decide who lives and who dies!"
