By the afternoon.
Igarashi's students had changed from the children to Xia Xi, Persimmon, and Kazami.
Naturally, what he taught changed as well.
He moved from the basics to more profound subjects.

It was what the ears heard, what the nose smelled, what the mind's eye observed...
To put it in more mystical terms.
It meant mobilizing every organ and every cell in the body to continuously receive signals from the outside world.
In theory.
Even a blind person who could not see anything could "see" that more real, clearer world after mastering this skill.
So the training process was not simply about exercising one's eyesight.
It was about gathering information from every direction and processing it at high speed in complex environments.
To emphasize this point.

And in the courtyard.
A dragonfly that happened to fly past was precisely pinned to a tree trunk by those needles.
The tips of its four transparent wings were lightly held in place by the needles.
Without injuring the dragonfly itself.
