Liu Jiahao transmigrates to the world of Hokage and becomes the worst dead-last in Konoha.
He can't use ninjutsu, is hopeless at taijutsu, gives away genjutsu for free, and can't even perform the Clone Technique.
The whole class laughs at him, and Iruka sighs.
Until the day the Six Paths of Pain descend from the sky.
“A bag of rice weighs how many floors?”
Everyone falls, and only Liu Jiahao steps forward.
Clutching an ordinary sword, he carves a streak of sword light through the pouring rain.
[Jiahao System alert: Mastery of One Sword Opens Heaven's Gate is full.]
The sky splits open.
Pain is stunned. “What kind of ninjutsu is this?!”
Liu Jiahao grins.
“This isn't ninjutsu. This sword strike is called Opening Heaven's Gate.”
From that day on, the shinobi world gains a new legend:
A good-for-nothing who can't form hand signs, has no Kekkei Genkai, and possesses pitifully little chakra.
With nothing but a sword, he cuts a god down to earth.
