Ah, there is a promotion crystal as Argus said there would be.
I could wait till I exit the realm and then take the promotion mission at the Magic Association branch in Winter City. I mean, this is what I should but the pressure is picking my brain.
I got a weird promotion mission. Now my brain was thinking what kind of shit hole I would find myself in. So after the bonding with the Nexus was over, I took the guidebook and searched for the promotion room that he had mentioned.
Though he only said that there is a promotion crystal present here, he never said where it is.
The Nexus is huge, much larger than what appeared outside. If not for the guidebook, I might have got lost.

The room where the promotion crystal was present looked very simple. This was probably so that the elements present in the room wouldn't cause any disturbances during the connection.
