Earth With Dungeon: Saving the World With an Economic Boom

It’s a small room of four and a half tatami mats, but it prevents penetration by skill.

I snap my fingers and use the remaining mana.

[Shadow Room]

Sakimori creates a room with dark walls, so he sneaks in.
He hunches over and creeps around.
I’m an old man who is acting suspiciously, to the point that someone might call the police.

Once inside, the room is small, but I don’t care.
I use all the mana I have left.
That’s zero for today.

[Equivalent Exchange Store]

A thin, translucent greenish monolith-like board about two meters high appears in front of him, and he jingles out a monster core.

The board shows many item names.
But most items are still grayed out.

When he selects one of them, the text becomes larger.

[Chain Store: Remaining number of required items E rank monster core 2/10000]

As he placed the hobgoblin monster core into the board, it created a slight ripple on the surface as it went into the water, and disappeared.

[COMPLETE! The Equivalent Exchange Store now has a chain store feature; it takes 10 mana to install one unit.
The amount of mana maintained is deducted at the time of use and used as fuel].

Then the letters, which had been gray, turned red, indicating that he unlocked it.

As if tracing them, the old man’s touching the inverted letters, the old man voiced his emotion.

“It’s been a long time …….
Ten years to make myself strong.
Ten years to release the chain store function…….
In the meantime, the world changed, and I was afraid that a magic school or an adventurer’s guild would get established, and I would get cut off as an old race.
…… It’s a much worse world now.”

[Let’s let the cream pans go next.
Absolutely, right? You promised a beautiful girl, remember?]

I hear Shizuku’s appetite-coated voice.

“You know, I’m shedding tears of emotion as I remember the last 20 years.
Wouldn’t it be nice if you cared a little more?”

The old man sends a thought that’s supposed to be a scene of tears and rejoices that he did it.

[So I’ve been waiting.
I stopped to ask for chocolate coronets and cream buns.
I’m so sweet, aren’t I?]

“Yes, yes.
You’re gentle, gentle.”

Shizuku sighs that she’s always like this but quickly regains her composure and grins.

“Rejoice, Shizuku.
It’s time for me to be the savior of the world.”

[On that note, can I have some extra melon bread.]

“No.”

Sakimori chuckles as he looks at the Equivalent Exchange Store because he calls the savior of the world such a thing.
