Terdungeon, basement level.

　He held his hand over the slime that had appeared.
　Not a gun, a hand.

"Repetition.

　Newly learned magic, magic that forces a monster to be defeated once it has been defeated.
　The slime disappeared and a sprout dropped.

　I picked it up and put it in the magic cart.
　It was the easiest thing I've ever done. Guns no longer missed at the level of slime, but I still had to focus on it in a certain way when aiming.

　In contrast, Repetition's magic doesn't require that, it just reminds you of the person you're casting it on.
　And--

The MP consumption is low.

　I only shot this one time yesterday, to help Margaret out, and I shot at the Dungeon Master in Nihonium.
　At the time, I felt weak, like I had used up all my MP. It was just one shot.
　But today it was fine, it didn't happen when I used it on the slime.

　Another slime appeared, and I used the repetition in the same way.
　The slime was killed instantly and the sprouts were dropped.

　I still don't feel like I've consumed MP.

　Repetition, a spell that instantly kills a monster once it has been defeated, and the MP consumed depends on the strength of the monster.
　It seems that a slime or so consumes very little.

'In a way ...... no, it's different. It's usually the strongest magic in this world.

　It's a magic that instantly kills monsters once they've been defeated, I suppose it's only useful in games, but I think it's the strongest in this world.
　In a world where everything is dropped from monsters, dungeon circling is "production".
　Production is a repeatable process, and the ability to run around monsters consistently is more valuable than anything else.
　It's not an exaggeration to say that the strongest monster you've defeated is the one that dies for sure, just by using magic.

The question is, how many times can this ...... strongest one be used?

　The consumption is low, but not zero, against a slime, it's a feeling, but it definitely feels a little bit MP consumed.
　How many times can it be used ......

　I used Repetition against the weakest slime.
　I used magic to defeat them and drop sprouts into the magic cart. When the cart was full, I'd hit the switch to collect the drops and send them home.

　I repeated the process.
　I kept repeating the process single-mindedly.

'...... style,'

　Eventually, my MP ran out, and after repeatedly killing enemies immediately, my MP ran out in half the usual time - around 3:00 in the afternoon laps.
　Even though my MP is S, as expected, it would run out after using magic non-stop for nearly three hours.

　Well, what's the result?

　　　　　★

　Back home.
　I've never been back at such a high hour of daylight on a day when I'm entering the tellurian.

'I'm home.'
Welcome home, Mr. Lyota.

　A three-story house, an open part of the first floor.
　There was only Erza there, which was now completely like a store.

　She was being dispatched from the buyer, Tsubame's gratitude, and greeted me with a smile.

''What's going on, you're early today.''
I just wanted to know how much we made today.
Oh, yeah.
What do you mean "still"?

　He tilted his head at Elsa, who smiled at him and asked back.

'Lyota-san, you've started something new.
Do you understand?
'I understand. There's a difference in the way you send it around as usual and the way you send it when you're doing something different from what you normally do.
I see.

　Maybe even a third party would be surprised by what they see.

So, here's the bank book.
I'll give you a minute.

　Elsa takes the passbook and writes down my earnings for the day.
　I was nervous and excited while I waited.

　After a while, Elsa finished her bookkeeping and handed me the account book with a smile on her face.

Here you go.
Let's see: "Let's see: ...... 3 million piro!

　The number on the bankbook was three million if you round down the fractions.
　I believe this amount is .......

''That's almost exactly the same as the previous day's record high.

　It's the same as when I pushed the envelope by sticking it out to show Margaret a good point.
　The same amount of money I spent when I pushed myself to the limit, and half the time I spent this time.

''That's great, Lyota-san, you've done your personal best in half the time, that's practically your personal be-''
It's a new kind of magic.
You learned?　The New Magic.
With a magic fruit.
Oh yeah, ...... awesome.

　I looked at the bank book while receiving Elsa's respectful gaze.
　The money that went out yesterday, the money that came in today.
　New magical abilities, and the time left until I earn my usual amount of money.

''I'm going to go to the dungeon one more time.''
Are you still going?
Yeah.

　He nodded, opened the bank book and showed it to Elsa.

'With just under two million to go, we'll be on the ten million mark in total.
Ah!　You'll arrive on time!　At today's pace.

　Elsa, who huffed, smiled at her and smiled at her.

'That's what I mean. I'm off.
'Good luck!　I'll do my best too!

　Encouraged by a small, gutted and enthusiastic Elsa, I headed back to Telldungeon.

　I ran out of MP, but no problem.
　I loaded my gun with recovery bullets and shot myself like a syringe to recover all my MP.

　The result of entering the dungeon again with a full tank of MP at S and going around the dungeon.

　On this day, I never saw one in the original world.
　He had created an account balance of 10 million.
