Naruto: The System Thinks I'm Weak, So It Gives Me the Rumble-Rumble Fruit

System + Rumble-Rumble Fruit + Nine-Tails Chakra + Eight Gates + God of War's Six Powers + Chakra Haki + Demon-Slayer Sword Enma

[With a System, break the chaos of the Warring States era with the power of thunder!]

Uchiha Zhanguo had transmigrated to the Naruto world three years ago, but he had never managed to awaken his Mangekyō Sharingan. That was until a ninja cat, transformed from a pirate System, brought him the Rumble-Rumble Fruit.

When a thunderstorm burst from his palm and blasted the roof off the clan leader's house, everyone in the clan saw the ridiculous sight of Fugaku with smoke rising from his head.

"This new jutsu... is a little hard to control." Zhanguo tried to save face, only to see Madara Uchiha's Rinnegan gleam in the shadows.

When the Konoha High Command plotted to wipe out the Uchiha Clan, he had mastered both Lightning Release and Haki, yet suddenly discovered Itachi's kunai pressed against the back of Mikoto's neck.

Heavenly Thunder Prison versus Tsukuyomi. Could the Rumble-Rumble Fruit really be the ultimate move for breaking Kotoamatsukami?

With Chidori Sharp Spear in his left hand, he pierced the Nine-Tails. With three hundred million volts of Thunder Greeting in his right, he flattened the Akatsuki. In this Uchiha civil war, let me, the Lord of Lightning, rewrite the night of the clan's massacre!
