Fran asked Adrian to calm the panicked followers and took Hill back to the top floor.
As Hill passed by Boen, he casually tossed him a shell.
He just realized this time that there might be areas near the Royal Palace where storage rings couldn't be used, and the Alchemy Academy was on the side of the Royal School closest to the palace. It would be more convenient for Boen to use the shell when attending classes in the future.
He had originally thought that only the inside of the Royal Palace shielded storage rings!
Although shells were convenient, very few people could get them.
Even Hill, who used to be wealthy, didn't have one.
Moreover, these shells were filled with moisture, making it impossible to take out items like alchemical bombs. Everything had to be stored sealed, and using them required an unsealing process.
So even if the shells could be used within the Royal Palace, there wouldn't be any danger.
