Three mornings later.
When Rein once again walked ashore from the sea, the faces of the people practicing swordsmanship on the beach were a mix of different expressions.
Seeing Rein stay underwater for at least fifteen minutes, Bask couldn't help but mutter to himself, "Damn, why does it feel like I'm retarded compared to Rein's learning progress..."
"It's really fucking demoralizing!"
A few young people nearby glanced at each other. They felt the same way but didn't say it out loud because of their vanity.
They were taught by the same teacher, but Rein seemed like an apprentice from an accelerated elite class while they were from ordinary classes; he had completed in one week what took them a month to learn.
No, it was even faster than that. Who could stand this!
The crew-cut man sighed to himself, "It looks like he has mastered it, spending just three days to master the Inner Breathing Technique. It took me a full five days."
"Now, there's one more in our batch."
