A Training Method That Overturns Common Knowledge

The vast deck fell into an inexplicable silence.

Everyone's gaze shifted in unison toward the cabin door.

They were eager to find out what exactly Qin Yu had prepared for the second stage of training.

Creak!

The tightly shut cabin door was pushed open.

Bepo, visibly thinner than before, appeared before them once again.

However, what they saw made their pupils suddenly contract.

"Teacher, aren't those broken Seastone cuffs? Why did you take them out?" Luffy was the first to blurt out.

The moment those words fell, everyone's nerves were stirred, and their gazes fixed on Qin Yu.

Everyone present clearly shared the same concern. Their
