"This was the inspiration Hugo drew from the metro," Isaac explained to Annan in detail. "He used the 'location' function of the pointer ritual, so the buoys marked on the elevators could accurately point to the different floors…"
The pointer ritual was a kind of spirit-summoning ritual. It was roughly similar to a spirit board or a pencil game in this world, using a three-ring dial marked with indications of toxicity, corrosiveness, and explosive potential to pinpoint the general characteristics of an unknown catalyst.
This was a ritual that alchemists had to master in the past.

Before Hugo's time, all the wizards had no choice but to honestly take the stairs. When the cafeteria opened at noon every day, the junior wizards would crowd together—no different from ordinary people in this aspect.
It was only after the adoption of the elevators that wizards avoided the unseemly situation of falling down the stairs.
