The first and only one (part 1)

Aster's pupils contracted a bit as he observed the inside of the castle, from the outside it looked no taller than 100 meters, but inside… he looked upwards and in a rough calculation he thought that the roof was about 4 or 5 kilometers from the ground.

In fact, after using his spirit sense he noticed this place had a similar design to Lilia's spaceship, there were many floors which could be used for difference purposes, of course they weren't customized yet and were empty.

There were only a couple of exceptions, the training room which was built at ground level and the living area on the second floor which had about ten bedrooms fully prepared.

And that was not all, since he had the master key, he could bypass the formations set to maintain the privacy, and see inside of the rooms, the bedrooms were quite spacious but nothing too crazy, the training room on the other hand… it was more like a city than a room.
