On the night of the genocide, Uchiha Kai saw his parents lying in a pool of blood.
Stimulated by extreme grief, anger and fear, he broke the limits of the Uchiha clan, skipped the magatama stage, and directly awakened the Mangekyō Sharingan!
Left Eye [Tianting]: Across time and space, connect to the highly technologically advanced Blue Star Dragon Kingdom in 2222!
Right eye [Divine Luck]: Build channels, transport items, and exchange resources between the two worlds!
Facing Uchiha Itachi approaching with a sword, Kai, who was exhausted of chakra, shed tears of blood in his eyes and sent a distress signal to that future civilization:
"I am Uchiha Kai, and I apply for... Fire coverage!"
Limited by chakra, he could not summon the Gundam, but the Dragon Kingdom sent [Individual Anti-Material Grenade] and [Nano Cutting Line].
Itachi: "Is this your Mangekyou Eye Technique? Why is there no chakra fluctuation?"
Kai raised the palm-sized silver creation in his hand and sneered: "Stupid brother, this is called technology. Art is not an explosion, it is a dimensionality reduction blow!"
From exchanging "Chakra Extraction Method" for "Gene Enhancement Potion" to exchanging "White Zetsu Cells" for "Individual Mecha".
Let's see how Uchiha Kai uses the tiniest supplies to move the entire ninja world!
It's a lot of mess, messing around
