Make the hole in the broken entrance bigger.

Iron wall bullets that go on at my pace slow, unusual, whether the opponent is a rift in space.

Shoot that into the four corners of the square, shoot and relay in the same place when the time is about to run out.

As a result of the continued shooting of iron wall bullets in the four corners, the entrance rift was large enough to allow each person to pass through, about the size of the door of the room.

"I'm coming."

"Be careful."

I nodded back at Nihonium, and I crept through the entrance.

It's a low-ceiling underground dungeon, like a pile of stones in carbon.

That stone emits a blue and white light by the way, drifting through the quietest creeps of the dungeons I've ever seen.

"Mr. Lyota."

"Celest!"

When I went inside, I saw Celest quickly.

She finds me and rushes over happy.

I ran over to her too.

"Are you all right?

"Yeah. Especially not"

"Right. The other adventurers..."

I was horrified at Celest's safety, while looking around - I was surprised.

Most adventurers in the blue and white light sit on the ground and relax.

Some use ingredients that appear to have been dropped in carbon for a banquet.

"... what is this?

"What?

"I imagined I was stuffed with more feathers. Why are you so relaxed?

"I owe it to Mr. Satoh."

A young man has joined the conversation.

Some adventurers are relatively small, which is why they don't seem weak. As far as gear goes, they're probably the type of adventurers who use speed and maneuvers to flirt with melee monsters.

"What about you?

"I am the acrobatic of the Elliott family"

"Elliott Family, Acro......"

It's a name like I've heard somewhere, but I couldn't remember it right away.

The acro keeps people grinning, no matter what my doubts.

"That was an emergency. I'm sorry, but the one who got hit disappeared. The level of emergency has risen."

"Then wouldn't you be in more of a hurry or panic?

"I don't know what to do with that, but once someone's blurry, Lyota said she'd be here if she didn't make it this far."

"Ooh...?

I'm coming...?

"If it's a bad case, Mr. Satou's coming, so it's only a matter of time before we're rescued. So if you knock them down, if you knock them down, if you don't knock them down, you can fight monsters."

"The monster suddenly disappeared. So, guys, oh, Mr. Lyota's here."

Celest explained to take over Acro's words.

"I see."

It was a little complicated.

On the other hand, I'm glad they trusted me that much, and some shoulder blushes I guessed were extreme inside in confined spaces.

"... but it's not important."

"Mr. Lyota!

"Hmm? Oops."

Panicking celest, chasing her gaze, one of the shots of the iron wall bullet had disappeared, the square had collapsed and had a long right angle triangle vertically.

He hurried to shoot an iron wall bullet to stretch the slope and also shot an additional iron wall bullet in the corner.

First aid, turn to Celest and the others.

"Let's just go outside. Celest, come out first."

"I'll stay, too. to the power of war when something happens."

"No, Celest needs to go outside. I would be more grateful for the possibility that I might be able to use the transfer room at times than the force of war"

"... I see, that's true. Okay."

While convinced, the celest has the look of being pulled backwards somewhere.

I was wondering if you wanted to stay that much.

"Let's go, this glue won't last forever"

"Yes."

"Acro, too, let everyone know. I keep this entrance."

"Okay."

Each of them moved out.

Celest is first creeping through the entrance and waiting right outside.

Acro ran behind the dungeon to convey to the adventurers who were relaxing and feasting.

"I can go outside, but it's unstable, so I'll hurry."

Acro's tone was truly imminent, either because he was actually looking at the entrance being closed.

In response to that call of Acro, the adventurers came one after the other, sloppy.

"Thank you."

I missed you.

Every time you pass beside me, the adventurers say thank you.

Of course not all of them are, a lot, lots of veteran prowess people are in here, and those people are appropriately prized.

"I'll always pay you back what I owe you"

And I also said.

Maintain the entrance with an iron wall bullet while dropping it off.

The entrance is narrow and only one person can pass at a time.

Therefore, the long line of serpents of the adventurer was naturally raised.

……

"What's wrong, Mr. Lyota?"

Celeste asking right outside the entrance.

"Maybe it's not enough"

With that said, I shot an extra iron wall bullet that was about to run out of time.

It takes four iron wall bullets in a set to keep the entrance smooth.

That set number and effect time, and the rest of the human column.

"About a third of them are going to be left behind."

"So you need to divide it into two parts."

"I want to avoid that"

"Why?

I reach out and point to Nihonium.

"Carbon is quiet now because Nihonium is holding it down. But to buy extra Iron Wall Bullets, you have to go back to Nihonium and defeat Poison Zombies."

"... no, you just need to get Nihonium to serve poisoned zombies now"

"No."

I argued no time with Celest, who had one breath free to argue.

I've already thought about that.

"I can't be here."

"... ah"

Apparently, Celest noticed, too.

Iron Wall Bullets are Poison Zombie drops.

The fact that you can also drop from Haglemon by Drop S makes it a secret within your peers that Drop S is in the first place.

Some of you may feel it, but I still don't want it to look clear.

So I want to get away from here once I buy the iron wall bullets.

"I'm leaving here, which means I'm closing this entrance once, but I want to avoid that if I can. I don't want to change the situation when it's stable."

I saw the simulation in my head if the iron wall bullet disappeared.

First, we go to an unpopular place, get Nihonium to help us refill the iron wall bullets and get back here.

So I hope to open the entrance again sooner or later, but if it doesn't work, I'll quickly get back to the mansion and use the transfer gate to fly to the carbon basement first floor.

Sometimes it sucks, if you can't use the transfer.

Given that possibility, I still want to somehow maintain this entrance in its present state.

Too much thought though.

"Thank you! That was helpful!

Thank me, young adventurer leaving Carbon.

Appreciation, and trust.

I want to avoid the current situation, the anxiety element that is being sent them.

"... you want to try"

"What?

"Look."

Either way, it's never enough as it is.

Then one set - no, two sets.

It's worth a try, even if you waste it.

That's what I thought, I took out the vanadium bullet, put two iron wall bullets in it, and then I shot him with a gun.

Double iron wall bullets instead of vanished iron wall bullets.

Then.

"You're late."

"Oh, you're not moving at all"

W iron wall bullets were even slower than iron wall bullets.

When I stared, I had the illusion that it was moving, but when I looked closely, it was still slow enough that it wasn't moving.

W iron wall bullets maintained one corner of the entrance.

Three other things nearly disappeared in the meantime, so I shot a regular iron wall bullet.

Keep an eye on it, the normal iron wall bullet almost disappeared again, so add - but there was no change in the W iron wall bullet.

Three horns advanced slightly with two regular sets of iron wall bullets, but the W iron wall bullets do not move at all and do not disappear.

The entrance was slightly distorted and trapezoidal because of it.

One more set, another set.

After 4 sets of conveniences, the W iron wall bullet does not disappear.

Double iron wall bullets fused with vanadium bullets were much slower and lasted much longer than normal.

I can do this!

I switched the other three corners to the W iron wall bullet as well.

The entrance stabilized.

Until then there was a sense of doozy to maintain, but it stabilized at once with W iron wall bullets.

"Should I?

"Oh."

Nevertheless, I can't lose my mind.

I concentrate until the end, staring at the change in entrance and W iron wall bullets.

Successfully rescued every adventurer trapped in carbon.
