After Selvih arrived, Hikaru took her and Anno down to his secret cave. However, Selvih soon turned his secret cave into an underground palace.
The cave was enlarged by a quarter of a stadium and decorated like an underground palace. The scariest thing was that Selvih could finish a job that would have taken a year in just one day.
Anyway, Selvih possessed a huge mana source, so heavy jobs could be completed easily. Hikaru felt that it was also reasonable, it was like building a territory, even though they didn't have machines to support them, they could use mana so they can get a lot of work done quickly.
Seeing the cave being transformed into an extremely magnificent and beautiful stone palace, Hikaru felt that Selvih not being an architect was a disadvantage to humanity, and a waste of talent.
Hikaru entered the palace, the inside was also decorated with very sophisticated furniture, the arrangement was also very reasonable.
