The "Rampaging" Pure Blue Space

Benjamin could not remember how long was the last time he was in the pure blue space.

Each time, the conditions he met to come here was quite different, but most of the time it was because he achieved a new milestone in his magic training. In this short period of time, he had surpassed the speed limit he could once go when flying, and continued growing slowly in magic, but did not experience much change. Thus, the pure blue space avoided him.

From his estimation, he felt that the next time he entered his dimension of consciousness would be together with the triangular rune.

But, in this totally unknown underground city, he saw a familiar rune, then through this rune, he entered the pure blue space. He totally did not expect this to happen.

With this, he was once again in the pure blue space, he looked around to see his surroundings.
