Finally, a Treasure!
After a few minutes of power nap, I felt refreshed.
Burning the clothes and cushions I slept on that were soaked with my blood, I further changed into a new set of clothes and continued my exploration.
I didn't think of checking out the insides of the coffins anymore as there was no more important need like previously. They were already dead long ago, and it would be distasteful of me to disturb their rest.
Though, there would have been no issues if they were my enemies.
Going upstairs would have been a better decision, but I still decided to check the other end of the crypt, now that the hidden enemy was gone.
And luckily, my decision was right, and I didn't have to waste any time as after crossing a few rows of sarcophaguses, I found a very imperceptible change in the taste of air.
Instead of the stale but iron-like taste prevalent in the crypt, I could feel a little fresh but moss-like taste that was common inside the dungeon.
