After entering the palace, Aren met with their uncle and looked at him for a few seconds as a flash of surprise flickered in his eyes.
The two brothers, Jin and Konish, requested their uncle to let Aren use the Elemental Zones, the facility they spoke about.
Afterward, Aren was led by a butler towards another hall in the palace.
This hall was mostly empty as it only had six doors in it and two sets of tables with four chairs at each of those tables.
Each of those six doors had a different name-plate on top of them.
[Demonic]
[Fire]
[Water]
[Darkness]
[Blood]
[Metal]
Aren first entered the [Fire] door and arrived in a thirty square meter room but...the room was wreathed with blazing flames flowing everywhere.
However, he was not feeling any heat or anything but could feel how hot it was. Basically, he was not negatively affected by the heat and flames since he had fire affinity.
