When Uzumaki Naruto saw Metkai for the first time, the man was standing on his head facing the sunset, his sweat hitting the soil and blooming into silent flowers.
"Young man, do you want to come and burn together?"
When Naruto became a disciple of Metkai, Naruto, who was no longer obsessed with making balls, practiced the shadow clone technique to the extreme, and learned the Eight Gate Dungeon under Kai's training.
Life suddenly opened the door to a new world - "What if... I let five thousand shadow clones open the door together?"
Then a mushroom cloud rose over the battlefield, and Teacher Kai knelt on the ruins and cried bitterly:
"Is this... The weight of youth multiplied by five thousand times!!!"
