I made the hole at the entrance larger.
Even if the opponent is a rift in space, the iron wall bullet that advances at a slow pace reacts the same as usual.
Firing it in all four corners of the rectangle, and when the time is about to expire, I fire at the same place.
As a result of continuing to shoot iron wall bullets at the four corners, the rift at the entrance became large enough for one person to pass through, about the size of a door.
“I’ll be back” (Ryouta)
“Be careful.” (Nihonium)
Nodding back to Nihonium, I passed through the entrance.
The inside of Carbon is an underground dungeon with a low ceiling, like a pile of stones.
The stone radiates pale light in some places, and it has the quietest and eerie of all the dungeons I have ever seen.
When I went inside, I immediately saw the appearance of Celeste.
She found me and ran up happily.
I also ran to her.
“Are you alright” (Ryouta)
“Yes, nothing especially happened.” (Celeste)
“I see, how about the adventurers—-” (Ryouta)
While I was relieved that Celeste was safe, I looked around and was surprised.
Most adventurers are sitting on the ground and relaxing in the pale light.
Some are having a banquet using ingredients that seem to be dropped from Carbon.
“……What’s going on here” (Ryouta)
“What do you mean” (Celeste)
“I was imagining that everyone would be in hunger.
Why are they so laid back” (Ryouta)
“It’s thanks to Satou-san.”
A young man joined the conversation.
Among the adventurers, he is a relatively small person, but that doesn’t mean he is weak, and as far as the equipment is concerned, he is probably the type of adventurer who makes full use of speed and effort to fight close quarters combat against monsters.
“Who are you” (Ryouta)
“I am Acro from the Elliott family.” (Acro)
“Elliott Family, Acro …” (Ryouta)
It was a name I had heard somewhere, but I couldn’t remember it right away.
Acro continued with a friendly smile, regardless of my doubts.
“That was an emergency, but the one who we had to battle has disappeared.
But the level of the emergency has increased steadily.” (Acro)
“If so, wouldn’t you be more impatient or panicking” (Ryouta)
“That’s right, but someone suggested something.
If it’s so dangerous, Ryouta will come.” (Acro)
“Oh, oh …” (Ryouta)
I will come ……
“If something dangerous were to occur, Satou-san will come, so it’s only a matter of time before we are rescued.
That’s why we were able to fight endlessly with monsters that wouldn’t be killed even if they were defeated.” (Acro)
“The monster suddenly disappeared here.
That’s why everyone was like “Oh, Ryouta-san has came.”” (Celeste)
Celeste explained to take over Acro’s words.
“So that’s it” (Ryouta)
This is a little complicated.
While I was happy that I’m being trusted so much, there was also a feeling that I thought that the inside was in an extreme state in a closed space.
“… Well, at least everyone is safe and sound.” (Ryouta)
“Hmm Oh woops.” (Ryouta)
Celeste said in a hurry, and chasing her gaze, one shot of the iron wall bullet disappeared, the quadrangle collapsed, and it became a vertically long right triangle.
In a hurry, I shot an iron wall bullet to extend the hypotenuse, and also shot an additional iron wall bullet at the corner.
I turned to Celeste and others.
“Let’s go outside for the time being.
Celeste, you can get out first.” (Ryouta)
“I will remain.
Just in case when something happens.” (Celeste)
“No, I rather not.
I’m more than grateful for the possibility that I might be able to use the transportation room at this kind of time.” (Ryouta)
“… I see, that’s true.
I understand.” (Celeste)
While convinced, Celeste looks like she has her back hair pulled somewhere.
While wondering if she really wanted to stay.
“Let’s go, the bullet won’t last forever.” (Ryouta)
“Acro also let everyone know, because I have to keep this entrance open.” (Ryouta)
“I understand” (Acro)
The two started to move respectively.
Celeste passed through the entrance first and was waiting just outside.
Acro ran to the back of the dungeon and communicated to the adventurers relaxing and having a banquet.
“We can go out, but we have to hurry because it’s unstable.” (Acro)
Acro’s tone was really approaching, probably because he was actually watching the entrance closing.
In response to Acro’s call, adventurers came one after another.
“No problem.” (Ryouta)
Every time I passed by, the adventurers gave me a thank-you nod.
Of course not all of them are so, there are many veteran talented people with many ☆, and those people have a correspondingly high pride.
“I will definitely return the debt”
Someone also said that.
While seeing them off, I maintain the entrance with an iron wall bullet.
The entrance is narrow and only one person can pass at a time.
Therefore, a long line of adventurers was created naturally.
“What’s wrong Ryouta-san” (Celeste)
Celeste asked just outside the entrance.
“This might not be enough” (Ryouta)
While saying so, I shot an additional iron wall bullet that was about to run out of time.
In order to maintain the entrance smoothly, 4 iron wall bullets are required in one set.
The number of sets, the duration of the effect, and the remaining line.
“About one-third is likely to be left behind.” (Ryouta)
“It means that you need to divide it into two parts.” (Celeste)
“I want to avoid that if possible.” (Ryouta)
I stretched out my hand and pointed to Nihonium.
“Carbon is quiet now because Nihonium is holding it down, but to get more Iron wall ammunition, I have to go back to Nihonium and defeat the poison zombies.” (Ryouta)
“… Then can’t you have Nihonium put out poison zombies now” (Celeste)
“She can’t” (Ryouta)
I immediately answered to Celeste.
I’ve already thought about it.
“It’s no good here” (Ryouta)
Apparently, Celeste also noticed.
The iron wall bullet is a poison zombie——a drop product from a rogue monster.
The fact that Drop S can also be dropped from Haguremono is a secret within the group.
Some people may be aware of it, but I still don’t want to show it publicly.
Therefore, I would like to leave here once to refill some iron wall bullets.
“If I’m leaving here, it will close this entrance once, but I want to avoid it if possible.
I don’t want to change the situation when it’s stable.” (Ryouta)
I ran a simulation in my head if the iron wall bullet disappeared.
First, go to an unpopular place, replenish the iron wall bullets with the cooperation of Nihonium, and return here.
It’s okay to open the entrance again, but if it doesn’t work, return to the mansion with haste and fly to the first basement floor of Carbon using the transfer gate.
Worst case is when it cannot be used.
Considering such a possibility, I would like to somehow maintain this entrance in this state as it is now.
But I feel like I’m thinking too much.
“Thank you! Thank you!”
A young adventurer leaving Carbon, thank me.
Thank you and trust.
In the current situation where they are escaping, I want to avoid anxiety factors.
“… Should I try it” (Ryouta)
“Take a look” (Ryouta)
In any case, it’s definitely not enough as it is now.
Then one set——no, maybe two sets
It is worth trying even if it is wasted.
Thinking so, I took out Vanadium bullet, put in two iron wall bullets, and then shot it with a revolver.
Double iron wall bullets instead of disappearing iron wall bullets.
“It’s so slow” (Celeste)
“Yeah, it’s not moving at all.” (Ryouta)
The double Iron wall bullet was even slower than the iron wall bullet.
When I looked closely, I had the illusion that it was moving, but when I looked closely, it was so slow that it didn’t move.
The double Iron wall bullet maintained one corner of the entrance.
In the meantime, the other three were about to disappear, so I shot a normal iron wall bullet.
Because of that, the entrance was slightly distorted and became trapezoidal.
One more set, another set.
The Double Iron wall bullets did not disappear even after 4 sets had passed.
The Double iron wall bullet fused with vanadium bullet was much slower and much longer lasting than usual.
This can be done!
I also replaced the other three corners with Double iron wall bullets.
The entrance was stable.
Until then, there was a slapstick feeling for maintenance, but it became stable at once with the Double iron wall bullet.
“Would it maintain” (Celeste)
However, I can’t help myself but worry.
I concentrated to the end and watched the changes in the entrance and the Double iron wall bullet.
And finally, we succeeded in rescuing all the adventurers trapped in Carbon.
