The airship began to descend, allowing Ron to observe the architectural structure of the school from a closer distance.
The walls of these buildings were made of "living sand coral."
It is a unique material capable of autonomously adjusting the internal environment.
When the external temperature rises, the walls turn to a cool blue, releasing a refreshing aura;
when the temperature drops, the walls change to a warm orange, emitting a comforting warmth.
Moreover, this adjustment is not mechanical but responds intelligently according to the magic power fluctuations of the people inside.
Different magic characteristics for each person mean the walls provide the most suitable environment for them.
"This material..." Ron's researcher's instinct was triggered: "Is it artificially cultivated or naturally formed?"
"Both," Samuel proudly introduced:
"The basic sand coral is a specialty of the Quicksand Lands, but our researchers have significantly improved it.
