Chapter 21 Trial Dungeon.
"Dungeon?!".
Dungeon, which used to be called a Disaster, was a phenomenon where a subspace was created where strong Miasma or 'grudges of monsters' accumulated in one place for years. It is not only a subspace, but it can also give birth endlessly to numerous dangerous monsters that would cause calamities if it's not addressed properly.
It can cause tremendous damage to the surrounding area, spewing hundreds to thousands of monsters in a single day, killing every living being in sight.
In some nations, including the Eira Kingdom, the state usually manages dungeons, using them as a source to farm a huge amount of mana stone, which can then be used as an enchantment weapon or magical tool like the one Jin owns, the bracelet.
"Have you tried it, Mrs Iris?".
"Well, yeah, in some place...". She nodded her head and looked at Jin in a probing manner.
As someone who reached Gold rank as an adventurer, Iris had filled herself with experience diving into a dungeon somewhere.
"Well, it was good then. Can you help me with something?".
"What is it?".
Jin took out the golden key he obtained from completing the quest from his bracelet and showed it to Iris. However, contrary to Jin's expectation, Iris only tilted her head in wonder and stared at the item completely blankly.
"What is this?".
