From the Start, I Swallowed the Yamata No Orochi Whole and Conquered Japan

[Devouring evolution + ruthless decisiveness + no saintly heroics + global catastrophe + domination of Sakura] Global catastrophe struck, and mutant beasts invaded! Sakura Country presented a national treasure to the world: the Eight-Headed Serpent! “This is the first mythical creature ever discovered on Blue Star, proving that the people of Sakura Country are the ancestors of humanity!” “The culture and history of Sakura Country are the origin of human civilization on Blue Star!” “All humans on Blue Star are descendants of our ancestors!” The whole world watched the livestream. Lin Jian, reborn, slaughtered the Eight-Headed Serpent on the spot. In front of everyone, he devoured the national treasure and awakened a supernatural ability! Sakura Country went ballistic, threatening to reduce him to ashes! But Lin Jian remained completely in control, awakening new powers by devouring one creature after another. His incredible strength made him unstoppable throughout Sakura Country! A week later, global catastrophe struck! Mutant beasts invaded! Standing on top of every Sakura Country leader, Lin Jian smiled like a snake. “So, what do you call me now?” “You are the king of Sakura Country!”
