'...I see.'

Ackster didn't know how long he had been practicing his swordplay. But after a while, he noticed that his sword was no longer making whooshing sounds as it tried to cut through the air. His swings were completely silent. They were also frightfully faster than before.

Ackster was no longer trying to cut the air. He was doing it. His sword cut through the air like light. His sword's path was no longer obstructed by something as annoying as air resistance.

'I guess this is what he was trying to show me.'

After more than a year, Ackster finally realized what the Sword God had been trying to teach him. It wasn't something as outrageous as Will. The Sword God really was just cutting quickly. He could probably have slashed slower when trying to teach Ackster, but he wouldn't have cut through the air then.

'I'm a fucking idiot.'
