I Awakened the Reincarnation Eye from the Start and Rewrote the Rules of the Ninja World

[No System + Satisfying Battles + Planning Ahead + Mastermind Boss] In Konoha Year 27, tensions between the nations of the ninja world were growing, and the Second Shinobi World War was brewing. The clans of the ninja world, seeking greater profits, sent their members to the battlefield to earn military honors. Dust Release, Scorch Release, the Sharingan, the Shikotsumyaku… The kekkei genkai clans dragged their ninja villages into one war after another! Dark red blood stained every corner of the Naruto world. After transmigrating into the Naruto world, Hyuga Haoyu became a member of the branch family. It took him eight years of struggle just to barely make it to genin. But in the end, he was still ruthlessly sent to the battlefield on a suicide mission! The young man recalled the Will of Fire he had learned at the Ninja Academy. His bloodstained face held nothing but a cold sneer. He opened the textbook on the Will of Fire once more. Every crooked page was filled with the words “benevolence, righteousness, morality.” But looking closely, he found two words written between the lines: “devour people”! This was, in the end, a world that devoured people! At the crucial moment, the Tenseigan awakened… And from then on, a mysterious force emerged on the battlefields of the Shinobi World War! This sick world needs to be healed! And it all starts with making Kirigakure great again! This is the story of a man who rose from a caged bird to become the God of the Ninja World. But what does any of this have to do with Hyuga Haoyu, a merchant with only genin-level strength?
