The Mischief-Making Demon King of Konoha, a Genius in the Anbu

Five-year-old Uchiha Yan was a transmigrator who had arrived in the Naruto world.

He became the younger brother of a distant relative of Sasuke Uchiha.

At this time, the Uchiha Clan had not yet been massacred. With the clan's fate and the dangers of the Shinobi World looming, the stage was set for the most eventful era.

After awakening the [Troublemaker System], all he had to do was keep stirring up trouble and causing chaos to earn rewards and grow stronger.

Third Hokage Hiruzen Sarutobi was tearing his hair out over the chaos at the Ninja Academy, hoping this demonic genius would hurry up and graduate.

Danzo made up his mind: The Uchiha Clan must not have another genius. Uchiha Yan had to die, and the Uchiha Clan had to be wiped out!

With Danzo pulling strings, Uchiha Yan joined the Anbu and became the youngest ninja.

Orochimaru: "Uchiha Yan says you can distill nitrogen from the air, then compress it to change the form of Wind Release and make something called liquid nitrogen? I've never heard of it, but it sounds pretty impressive!"

Madara Uchiha furrowed his brow: "A little brat blew up the moon...?"

Uchiha Yan: "I didn't mean to at first. Who knew I'd accidentally become Naruto? That's how things ended up like this!"
