The Third Hokage Is So Decisive, Konoha Is About to Turn Upside Down

Konoha's Byakugan has been stolen, and Xia Yi transmigrates into the aged Third Hokage! He thought he could only watch Neji's father meet a painful end, when suddenly, a mechanical, ethereal voice rings in his mind! [Ding! Congratulations, Host, you've bound a daily sign-in System!] [Day One Reward]: Flying Thunder God Technique! [Day Two Reward]: Return to age 25! [Day Three Reward]: Sealing Technique: Adamantine Sealing Chains, plus Uzumaki Clan bloodline! [Day Four: Master the Mystical Palm Technique] [Day Five: Kotoamatsukami x1] ...(After the seventh day, awaken the sub-System: [Earn Points by Getting Under People's Skin]!) “Oh, nice!” Xia Yi eagerly accepts the rewards without hesitation. “Hah! Hiashi Hyuga! As the Third Hokage, I won't let you die before your time!” “Naruto, how about Grandpa adopts you as his grandson?” “Danzo, I'm the Hokage! Starting now, Konoha will immediately end all measures to marginalize and surveil the Uchiha!” In public and in private, Xia Yi takes the name Sarutobi Xia Yi! He is no longer indecisive, and he will no longer marginalize the Uchiha! We're one of the Five Great Nations, after all. Of course we're going to unite the ninja world!!! Years later, this newly risen ninjutsu professor earns a name that shakes the ninja world: Xia Yi, the “God of Slaughter”! [So what if you're Otsutsuki!? Set foot in Konoha and you'll still be forced to your knees]
