Naruto: I Became Tsunade's Disciple and Awakened the Filial Piety System!

Shenyue transmigrates into the Hokage world, in the year 37 of Konoha.

What? The Third Shinobi World War is about to break out?

No need to panic... Fortunately, Tsunade takes him on as her personal disciple.

And he activates the "Strongest Filial Piety System!"

As long as he shows filial devotion to his master, he can grow stronger.

Tsunade: "Good disciple, use your Hunyuan technique to give your master a shoulder massage..."

Shenyue: "Are you telling me what to do??"

The Shinobi World War:

Countless powerful fighters gather and launch a devastating assault on Konoha, leaving it in grave danger.

At this critical moment...

Shenyue: "Master, are you tired? Let your disciple give you a massage."

"Master, your disciple made a box of anti-aging beauty cream, specially as a gift for you..."

Tsunade: "Huh???"

P.S. A thoroughly satisfying power fantasy, absolutely no poison!
