The design of the “Sewer” had precedents in this world, though it was by no means the perfected modern underground pipeline system of the original world.
In the southern part of the Green Empire, specifically the coastal city of Enor where Latina lived, there existed a prototype of the medieval European-style sewer from the original world.
Frank combined this with the modern underground pipeline network described by Su Yao to design an “Otherworld Sewer” system suitable for inland cities.
Of course, where there’s a sewer, there must also be a “Wastewater Treatment Plant.” The issue of its location was entrusted to Frank, while the design itself had already been solved by Su Yao.
The town’s domestic wastewater and natural precipitation would first settle in the “First Reservoir” here for a period of time before undergoing a simple filtration.
Some of the sediment at the bottom would be manually dredged, then fermented into fertilizer to be sold to nearby villages.
The residue would be handled by a monster called the “Sludge Monster,” a creature resembling the “Stinky Mud” from a certain pocket monster series.
It could convert the excrement and residue it ingested into defensive sludge and magic power expelled from its body.
Su Yao could summon them through the Shop for two hundred DP each; of course, he could also buy them outright. Such monsters were quite common in swampy areas.
After this initial filtration and settling, the wastewater would flow into the “Second Reservoir,” where water hyacinth-like plants and a monster called “Mayfly Water Algae” would perform secondary purification.
It was important to note that if the “Mayfly Water Algae” multiplied excessively, they would generate toxins in their bodies, becoming a disaster much like locusts in the original world.
Therefore, another monster called the “Star Snail” was introduced here to control their numbers.
This treatment turned murky wastewater into something that appeared relatively clean, which was then discharged via waterways into nearby rivers.
By the way, these star-shaped snail monsters needed to be caught regularly, and their excrement left on the reservoir bottom had to be periodically removed by emptying and cleaning the reservoir.
No choice—wastewater treatment was just as troublesome in a magical world as it was anywhere else.
What about the wastewater during reservoir cleaning? Just build more reservoirs and rotate their use, of course! Didn’t I say I’m a genius!
With the “Wastewater Treatment Plant” design completed, the first batch of construction projects was finalized.
The initial works included a “sewer pipeline network” suitable for a small town, a three-story building for the Adventurers’ Guild branch, an inn designed to profit from adventurers, and a trial-version of the “Wastewater Treatment Plant.”
Su Yao couldn’t call upon his own construction team busy building the brick kiln here, so he had to ask Hilvi for some assistance.
She just needed to help him gather some manpower.
After all, it was town development and required close to a thousand workers even with the reduced number of buildings.
There was still a shortage of about three hundred workers.
What went hand-in-hand with that shortage? Undoubtedly, money.
Now he kind of understood why there were so many unscrupulous bosses in the original world.
“Chlorel, how many Gold Coins do we have left now?”
“Just over ninety. By the way, the monthly wage payments to employees cost over twelve hundred Gold Coins.”
“Twelve hundred?”
The intimidating figure wasn’t surprising, considering there were over 150 employees, and she paid them outrageously high wages.
Twelve hundred Gold Coins sounded frightening but was actually about half a month’s revenue for the Maze Tavern.
The reason for such poverty was that Su Yao had many other expenses. Just producing samples for “Manhole Covers” and large “Sewer Pipes” alone had cost a hundred Gold Coins.
Purchasing bulk building materials consumed another three hundred Gold Coins.
There were still many modern products like “Water-saving Valves,” “Filter Nets,” and “Flush Toilets” that had to be specially designed and prototyped, which would require a lot more money.
The blonde little girl’s beautiful ruby eyes flickered with a shape like a “mosquito coil.”
“How about recovering the employees’ wages first? After all, you paid them half a month in advance, and reclaiming it shouldn’t violate the ‘Labor Contract.’”
“No, that would affect ‘Employee Motivation.’”
Although the wages were paid early for easier end-of-month accounting, seeing those people so overjoyed made Su Yao reluctant to disappoint them.
It was better if only the adventurers visiting the Maze Tavern had their wages reclaimed.
Wait! Reclaim wages?
Yes, that’s it!
“Chlorel, could you please go to Moravia and bring Hilvi here? I want to discuss something very important with her.”
Su Yao had come up with a perfect plan to reclaim the temporarily unused “wages” from his employees.
Since the dungeon staff’s meals and accommodations were covered, their Gold Coins just sat idle in their hands without multiplying.
It made more sense to collect them together and let her invest the funds into town development.
With the profitability of her enterprises, paying them back with “interest” would be easy.
This solved the funding shortage, gave employees extra income called “interest,” and accelerated town construction—all in one move!
Although he had said it once before, he really wanted to say it again—he was such a naive fool!
“Hmm? Aren’t you coming with me?”
Why did that question sound odd? Why was Chlorel looking at him with such distrust?
“No, I still need to train a bit more; today’s goal isn’t done yet.”
“Alright, but if I come back and find you’ve seen something you shouldn’t have, don’t blame me if I hang you up next time before you go out~”
Yikes! What did she mean by “hang me up”? I already said that last time with Lilith it was… just a fitting session!
My heart and deeds are as clear as a mirror, all in the name of justice!
That’s right, cuteness is justice!
“Don’t worry, I absolutely won’t make the same mistake twice! You’d better get rid of those weird clothes early.”
“No!”
Su Yao: “???”
“Ahem, those clothes are clearly made with valuable materials and workmanship; throwing them away would be too wasteful. I’ll find the right opportunity to give them away when I get back.”
“Can you send along those strange ropes and props you brought back too?”
“Definitely not! If you mess up again, I’ll need to use them.”
What do you mean mess up again? She must have triggered some terrible XP. She’s supposed to be the master, not me!
“Hmph!”
Su Yao said no more. Anyway, once Chlorel left, he’d dig out all those sexy outfits, ropes, blindfolds, and the like, then use the Dungeon’s abilities to…
“Wait, what are you going to do again? I haven’t done anything yet.”
“I just have a bad feeling you’re planning something naughty, so better safe than sorry…”
Good news: this time she wasn’t wearing anything scandalously embarrassing; bad news: Chlorel had come over with ropes and props again.
“I protest! Mmmph mmm…”
