I walked inside the training dimension.
It was a vast green open space...
Similar to the tournament arena.
The air was calm...
And the grassy ground stretched endlessly into the distance.
I stood in the center.
Summoned several blades.
Then...
Tried once more to create the smallest number possible.
The smallest blade I had managed before...
Was five centimeters.
But my current plan...
Required something even smaller.
I continued trying.
Again and again.
Then...
Within a short time, I succeeded in creating a blade only three centimeters long.
"Not enough."
I whispered.
"It has to be smaller."
I kept trying.
An hour passed...
Then another.
Nothing changed.
The smallest size...
Remained three centimeters.
Considering how quickly I achieved the three-centimeter blade...
I had assumed a bit more time would make further progress possible.
So I continued.
Suddenly...
A headache began taking hold of me.
The unmistakable warning sign.
I tried again...
