Naruto laughed when he heard this: "Sasuke, I swear to become Hokage. Man, this Hokage... you can do it right or wrong, I, Uzumaki Naruto, said, no one can stop me."After Sasuke heard this, his body began to tremble uncontrollably.I'm shaking with cold, when can I, Uchiha Sasuke, stand up. .........This is a ninja world that doesn't talk about science but only ninja studies.
