Looking at the back of the open wall, I saw a small room about two tatami mats in size with a small platform in the back that looked like an altar. I think it’s similar to the altar I saw at the end of the beginner’s dungeon in the southern village.

— And on top of the altar, there was a small bag.

Slowly, I approached the wall and saw that it was open to the room.

A door? A wall? It was about 30 centimeters thick and quite bulky.

“… When you enter the room, the door slams and you are trapped! Right? This is it right!?”

You’re not going to have a classic punchline like that, are you? Yeah, I don’t think so… I think I’m just setting the flag myself. Let’s stop…

I never thought I would be able to enter the room, grabbing the bag on the altar I dashed out of the room.

“…It’s not like it’s a trap or anything, is it? “

I was relieved and looked at the bag in my hand.

The bag was made of some kind of brown leather, about 30 cm wide and 20 cm long. There were belts sticking out from both ends of the bag, with some kind of hardware to adjust the length. It looked like a waist pouch in shape.

I unfastened the clasp of the lid and opened it up—

—There was only darkness.

“…this is…”

What is it? …No, I have a vague idea, but I’m not sure yet. I’m sure that the bag that was placed on the altar in the hidden room of the dungeon was not just a bag, but I was surprised by this kind of thing that surpassed my common sense at once, or rather, my mind could not keep up…

I put the bag on the floor, and slowly put the spear in my right hand from the pointy end into the darkness inside the bag. The spear was swallowed by the darkness for 10 cm, 20 cm, and then 30 cm. It clearly exceeded the length and width of the bag. As he continued to sink the spear into the darkness, it disappeared into the bag by 40cm and 50cm, until only the blade of the spear remained. Even if I sank the spear that far, it did not reach the bottom.

So I thought about it for a while.

“Hmmm… should I let go of the spear…?”

Actually, this bag might be a bag that erases what I put into the darkness, and I can never take out what I put in. It’s possible that it is something like that… I’m not sure what conventional wisdom is, but I don’t have enough information to deny such a possibility. These days when I’m not sure what could be considered common sense. It could even be a mimic bag that bites you when you stick your hand in it.

“But you can’t tell until you put something in and verify it.”

When I let go of the spear while saying that, the spear disappeared into the darkness of the bag.

Now, here’s the problem. In order to confirm the effects of this bag, I need to stick my arm into this darkness and try to pull out the spear.

…Well, I think it’s okay because this could be what is called a [Magic Bag], but … I’m not sure.

“Hmm…”

Or do I have to take this risk and verify it? If you take it to the guild normally and show it to the staff, it should be able to determine something. That wouldn’t be a hassle.

“… No, it’s no good.”

I heard that a [Magic Bag] is a valuable item. I’m not sure how valuable it is, I’ve never seen one in person before. It’s precious to that extent. At the very least, it’s not the kind of item that a D-rank adventurer would have. If that’s the case. I want to refrain from taking any action that would make it known that I have such an item in my possession.

In other words, I have no choice but to verify it myself, even if it’s a bit risky.

“I’m sure I’ll be able to… figure it out! I can handle it!”

I put my mind to it and thrust my hand into the bag.

As my hand was swallowed up in the darkness, something cool enveloped my hand, and I felt a strange sensation in my head.

“?”

I could somehow tell by my senses that the spear was somewhere around here. That’s what it felt like. I followed the sensation and tried to search for it with my hand, and the grip of the spear appeared in my hand, so I grabbed it and pulled it up.

Out of the darkness, the tip appeared and then the handle, and then the pommel, and then the spear came back.

“Is this bag a [Magic Bag]?”
