Seeing the floating of the rune crystals, Lucius was surprised. He had not thought of them acting like this.
"Hmm… didn't expect the density of these rune crystals to be lower than that of oil. But is this the same for all rune crystals or just these?" Lucius muttered to himself.
He pushed aside his thoughts for now and focused on the task at hand. Once the Rune beast crystals were added, most of the preparation was done and he only needed to wait for the user to appear.
Lucius closed the metal box and waited for Arius.
~CREAK~
The second door of the inner hall was opened and a masked Arius could be seen behind it.
"There you are," Lucius spoke.
"Weren't we going to meet at night?" Arius questioned.
"We were, but the situation changed. Plus, I was able to set up things much earlier than I thought. So it's not really a problem, anyway." Lucius answered.
