The Imperial City of Beorant is beautiful, and on a civilized level, the sewer is maintained and clean.

From what I hear, measures on environmental and hygiene aspects were actively taken from the previous generations of His Majesty the Emperor, thanks to which no plague or other epidemic has ever spread.

I will, however, be stunned at the southern tip of the imperial capital, which I have tried for the first time.

There are several rivers flowing into the imperial capital, all of which are upstream to the north.

As a result, downstream of the river, which is serviced for sewage, there will be massive flows of debris and other filth that flow and accumulate from upstream.

Inevitably, there was a bad smell coming in from the sewer at the southern tip of Teito, and years of accumulation had snubbed something dos black on the surface of the sewer that made me feel sick just watching.

Sometimes emperor citizens of the lower classes and servants of lower standing are driven out in each house to work on cleaning the sewer...

Well, you can't think normally and take it that seriously, can you? Nobles will never look at sewers.

... and well, for that reason, I went out of my way to clean you up.

I had a pretty clean habit of this, and even if I make a mistake, I touch dirt directly. Oh, my God. I'm an absolutely nasty type of person. No, I don't think humans like to touch dirt.

But I have magic. If you don't like to touch it directly, we're just talking about processing everything without touching it.

This is nothing, I'm not doing it because someone ordered me to, it's simply volunteering.

If the plague is an epidemic, catastrophe is a good place.

Exactly with my magic, I don't know if I can get rid of the virus in my body. So we need to strike measures before those damages occur.

I'm sure His Majesty the Emperor doesn't know the horrors of plagues such as Black Death (Pest) either. Simply because the aim was to keep the Imperial City clean.

Fortunately, or hatred, it seems that there has never been a massive plague spread in this world. I don't know a long time ago, but even if I asked Chancellor Cellard, who would at least have in-depth knowledge in many respects, he said I had never heard of such an example.

Yes, I mean, I'm the only one in my previous life who knew about the threat of a serious plague. Thank you, Dr. Kinoshita of Social Studies!

For not fighting on the front lines, why not contribute to people as a force under these edges.

When I break in from upstream of the sewer, I activate the magic of blowing strong winds from behind me first. Spray the smell of intense sewage. Then light magic for lighting is also activated.

Subsequently, 'air', 'water' and 'rock walls', which make up the sewer, are given their names respectively.

And give a name to the 'space' in the sewer to multiply all matter quantities other than the one you just named by zero… that is, zero matter quantities and “extinguish” them.

Immediately after the magic activates, the stubborn and persistent dirt that was creeping into the sewer disappears and is reborn shiny. Well, nice.

Now I'm wearing this diamond sharpener for 19,800 yen! Cheap!

Keeping motivated by such a solo play, I walk through a series of magic as I come through a dim sewer.

If you want to inadvertently mistake the magic effect range, there is also a risk that the sewer will collapse. We concentrated properly, carefully cut the area and let the dirt disappear one after the other.

Also, care should be taken not to wear dirt coming down from the top. If you eat something like that, you won't be on that level wanting to die or anything.

The sewer was strewn underground like a maze, and although I started with a light feeling, I was gradually losing my mood.

Still, I'm getting used to it from the middle of nowhere, and when I continue my cleaning activities while also using spells that speed up travel or greatly expand my magic range, I finally see light forward. Apparently, it's an exit.

There may still be some leftovers, but we focused on the polluting south in particular, so, well, we'll be fine.

I'll give you a break around here for today.

I finish cleaning the basement and get out of the sewer exit satisfactorily. Then the exit was surrounded by people who didn't recognize it.

Surprised to observe them closely, they are apparently knights belonging to the Southern Guardian Service of Central Command.

When they looked at my face, they came up with a very bewildered look and talked to me.

"Oh, um... it's Sir Sephilia, isn't it? In the sewer, what the hell...?

"Hey, I was an uncle"

Hearing my response, several of the knights peered into the sewer. And to so much beauty, I said, "What!?" I raise my voice of consternation.

Hehe, you must be, you must be. I couldn't help but be surprised if the dark space where everything up, down, left and right was covered with hedro until just now was so shiny.

... my clothes, they're not dirty, are they? I don't like the smell. Reggie is going to look disgusted.

Confirming the smell of the cheap clothes they were wearing so they could get dirty, that's what they've been asking me again.

"Heh, is it an order of His Majesty? I haven't heard of any such plans."

"I was going to do it. Because I didn't want to."

To my answer, all of you knights who come looking at incredible things.

Wasn't it very nice for the aristocrats to clean their own sewage? Well, even if I say noble, I'm a window clan.

Nevertheless, the fact that they were waiting here seemed to have been noticed that I was doing something underground. Why not?

Oh, could there have been a bad smell coming from the sewer exit because I've been letting the wind blow in the basement all this time?

I still have something to say. As I fled them, when I activated the weight manipulating magic 'Stand Up (Moonwalk)' and weighed a sixth, I jumped straight up and landed on the roof of a nearby building.

"Make this a nightmare."

I left them alone for once, but I followed the scene.

If I had a 'Sir Dirt Handling' or some weird alias later, I'd just bust it......

After that, when I finally went to see the downstream of the river that flowed out of the Empire City, it seemed like there was an accumulation of evidence, raw waste, so I magically wiped them out, too.

Hmm, magic is handy after all. Excellent.

Science in previous life was great, but there are things that science can't do.

Conversely, is there something magic can't do, etc., so is it a long, short time around?

Science...... if there is an appliance or something, will chores be easier?

Is that it? But if I were you right now, wouldn't I be able to afford as much as reproducing appliances?

Ha......!? An overwhelming sense of money making! Kikupi!

If you want to make real money by making this a business, you're not going to have any trouble with the money for the rest of your life.

Well, with my skill, I'll increase it, whether it's gold or gems.

... If you find out because the law prohibits you from doing that, besides being troublesome due to magical constraints, you're guilty of summary death.

All right, I'll stop by the Imperial Library's library library for a little while back and see you in magic research. What if...!
