A month later

<Quest {Conquer a dungeon} is completed.>

<Questline {Hunter's Path} updated.>

After killing the monster, I put the stone into my magic pouch. Then, started walking around to grab other loot in this place.

'There should be a chest behind the coffin.'

And just as I thought, a chest was hidden behind the coffin.

Normally that chest would be opened by injecting a person's mana into it, but since my core was sealed, I wasn't able to do it, well, at least normally.

Directing the lightning mana in the air to the chest, I opened it. 

Inside, there were a bunch of plants, some potions, and a key.

'This key is a pretty important item in the game.'

Remembering that, I put the key into the pouch. 

And then started waiting for the dungeon to be closed while eating my meal containing dry meat with soup.

While I was adventuring and fighting with monsters, I observed quite a lot of things.
