Capítulo 163: Body-Strengthening Technique

The practice field was rather wide.

Seiji was unable to see every part of it clearly due to various facilities on it, but even the visible part was in no way smaller than a basketball court. There were at least 20 meters between the ceiling and the floor.

There was such a huge space underground, so how was it created? When was it built?

Seiji had several questions in his mind.

But none of them were really important or necessary to ask.

"You looked over the information I gave you last night, right?"

"I did."

"Can you understand it?" Natsuya blinked curiously.

"Mostly…" Seiji thought back to what he'd learned last night.

The pornography book… cough, the [Body-strengthening Technique] manual was easy to understand. In fact, for an otaku like Seiji, who possessed a wealth of knowledge regarding various mystical 2-D elements that were far more complex, detailed, and mysterious, this was akin to a beginner’s textbook.
