Naruto: AFK System Novel

Yoruha finds himself reincarnated into the Naruto world as a freshly enrolled student at Konoha Ninja Academy. An unprecedented AFK System becomes his greatest asset:

[One day of AFK: Harness and expand your chakra reserves beyond natural limits!]

[One month of AFK: Achieve mastery in taijutsu, unlock the Eight Gates' potential, and become a Taijutsu Grandmaster!]

[One year of AFK: Dominate ninjutsu arts, penetrate ninjutsu's deepest secrets, and breach the Kage-level threshold!]

[Three years of AFK: Command Yin-Yang Release power, transcend illusion into corporeal form, and perfect the Sage Body!]

Chakra control, taijutsu combat, ninjutsu techniques, kekkei genkai activation...

Growth demands no effort—merely AFK and ascend!

When Yoruha finally enters the Six Paths realm, the entire ninja world trembles in his wake.

Even the legendary Jiraiya finds himself bewildered:

"You've never undergone serious training, yet your ninjutsu surpasses all expectations. What sorcery is this?!"

Caution: Rapid protagonist power scaling.
