Naruto: Leading the Ninja World to Conquer the Multiverse!

Also known as: What? The God of Shinobi Is Leading the Hidden Leaf in a Rebellion?! and I, Hashirama, Will Crush Everything!

Li Tiezhu wakes up to find a handsome, white-haired man sitting on his desk, demanding, "Big Brother! Are you seriously going to make that guy Madara Uchiha the Hokage?"

Tiezhu: ??? What? I've taken over Hashirama Senju's body? And I've only got two years left to live?

To survive, he has no choice but to keep playing the part. Only after he kills the daimyo and joins forces with Madara to unite the ninja world does his system finally upgrade:

Congratulations, host, on conquering the ninja world!
Reward: You may open one random portal every year!

Years later, when Urashiki and Momoshiki Otsutsuki attack, Tiezhu sneers, "The Otsutsuki clan? So much for them. Who the hell does Otsutsuki Yashimo think he is?!"

"Akainu! Erza! Esdeath! Kars! Saitama! Vegeta! Get them!"

Esdeath excitedly charges forward atop a Velkhana.

Erza casts Requip Magic-Flight Armor.

Saitama: "But I can't fly!"

Vegeta: "Trash. They're not worth my time!"

Major Anderson: "My Führer, I love war. Please, let me take command!"
