The deep storage unit was a useful item from YGGDRASIL that could store a near infinite amount of a single type of material. They were textureless metallic spheres that could be changed to any size for convenient storage and access.

Genjiro was currently walking down the hallways of the 9th floor of Nazarick in his human body, twirling two of these storage units in his hand like a pair of baoding balls.

It's strange to think that metric tons of urine and feces could fit into two tiny balls, and even stranger to think that they're light enough for me to carry in one hand. He brought his other hand up and rested his jaw on in. In order for this to not go against everything I know about the conservation of mass and energy, it must work in the same way our pocket dimensions do. The sphere itself must just be a gateway to its own pocket dimension where the urine and feces is stored in earnest, which is why we can freely alter its size and weight.

He looked at the sphere that was labeled "Urine", Still, to produce so much urine in only three days… They must have been drinking tons of extra water to try to please me. He chuckled a little underneath his hood, I'm only interested in the urine for it's nitrates, you're all defeating the purpose of producing more urine if you're just going to end up diluting it.

He reached the Pleiades's quarters and was about to open the door but stopped when he heard voices from the other side. Girl talk? Don't mind if I do. He focused his tracker skills and put his ear to the door.

It was Lupusregina speaking, "En-chan, you're such a naughty little girl~ I still have three day old web in my hair, su~"

There was a cute and juvenile voice in response that must have been Entoma, "With all do respect nee-san, I know you liked it."

Ha! Way to go Entoma, that sounds like something I would say. Genjiro scrunched his eyebrows a little, Wait, that is the exact immature and condescending response I would say

Genjiro shook his head and wrote it off as a coincidence, deciding it would be best to stop his eavesdropping.

He opened the door to see that it was just Lupusregina, Entoma, and CZ in the room. They were all in very relaxed positions, probably enjoying their free time, they saw him in the doorway and stood up and bowed.

"At ease, I need to borrow Entoma for a while."

"Hai!" Entoma bounded to the area near the door where she kept her shoes and socks, visibly happy to be of use to her creator.

Genjiro was watching her put her shoes and socks and started to say "Hehe, if you put them on like that, you're going to get scol-", then suddenly his eyes went wide. D-Did she just…! No, there's no way! I'm literally the only person I know that does it like that!

He had just witnessed Entoma put on her right sock then right shoe, tying her right shoe, then her left sock and shoe, then tying her left shoe. I know for a fact that I didn't put such an oddly specific thing in her character description. Did she hear of me doing it like that and is mimicking me? No, no one should have seen me putting shoes on like that.

He recalled Ainz's words in his head, "I think you'll quickly find out that their character descriptions aren't the only thing that influence their personalities."

This isn't just a matter of personalities Ainz! This is just too precise! Exactly how much do the NPC's take after their creators!?

Entoma saw that Genjiro was shaking and making a scary facial expression "Genjiro-sama? Is something wrong?"

He did all he could to suppress the shakiness in his voice, "N-No. I'm fine, please follow me"

He turned and walked out the door with Entoma close behind him. That's right, there was that comment she made earlier as well. This needs to be investigated further.

Genjiro calmed himself down and focused on his walking. I'll do everything I can to figure out what's going on later, we have a job to do right now.

.

.

Genjiro and Entoma had just arrived by gate and were walking through the Great Forest of Tob. It was a beautifully sunny morning and light was filtering through the leaves above.

"Might I ask where we're heading Genjiro-sama?"

"We're going to the safehouse that Aura has been constructing, I've been having her and Mare prepare something for me on the side."

He arched his neck as if he was trying to see down the path ahead of them a little clearer. "What we're doing needs to be kept secret from the humans of this world, so normally we would just do it on the 6th floor of Nazarick. However, what we're doing is also quite a smelly process and I don't want to stink up Mare and Aura's home too much."

Entoma's voice came from next to him "Does it have to do with the waste you've been collecting?"

He smiled and patted her head, "You're correct. Look, we're here."

Ahead of them was a large complex of battlements and wooden stockades. Goblins and other monsters of the forest were totaling logs around and countless other errands. They seemed to building some grand wooden statue of a certain undead magic caster.

Aura spied the pair from atop the battlement and jumped down, making a 'V for victory" as she landed. She ran giddily towards them

"Welcome to my fortress Genjiro-sama!"

"Thank You for having us, where's your brother?"

"Mare! You're being rude to lord Genjiro! Hurry up and get down here!"

There was a sheepish reply from up behind the battlements "I-I can't, onee-chan..."

"Mare!"

"O-Okay.." A gender confused dark elf child dropped down from the battlements and ran toward them

"Hurry up!"

"H-hai!"

He arrived before them and curtsied "I-I am sorry for making you wait, lord Genjiro"

"Don't worry about it, did you complete that project I had you do?"

"Y-Yes, please follow me."

Mare led them to a clearing behind the fortress. As they walked they drew gazes from the various goblins and forest monsters that were working, but they saw the two impossibly powerful elves and decided it would be best to stay out of their way.

In the middle of the clearing was a ditch roughly the size of a football field and two meters deep. Standing next to it was a massive pile of dried cut straw.

Mare spoke up as they were arriving "I made the ditch just like you asked, I covered the walls and floor with clay like you said as well.

Getting closer, Genjiro could see that the ditch was lined with a thin layer of brownish tan clay.

"Oh! And I also collected all the straw into that pile" He indicated the pile of straw next to the ditch.

"Good work Mare, this will work perfectly to keep the nitrates from leaching out into the soil"

"Genjiro-sama!" They turned around to see Aura leading a caravan of various heteromorphs

"Here's the 2 elder liches, 2 basic fire elemental, and 24 skeletal workers you asked Ainz-sama to send here!" (Note: I was really unsure what I wanted to make the basic fire elementals to look like, so for now, just think of the primal fire elemental from the anime but much smaller)

Everyone lined up and bowed before Genjiro "Excellent, I need one of you Elder Liches to step forward"

One of the Elder LIches stepped out of the crowd

Genjiro nodded, "Your name is now Peter, glad to have you on the job site"

Peter talked in hollow voice and bowed "I bow before the supreme one"

Genjiro nodded again, "Okay, Aura, take the other Elder lich, one of the fire elementals, and 6 of the skeletal workers to the other job site I told you to make earlier."

Aura bowed and left with the heteromorphs, leaving behind 18 skeletal workers and a basic fire elemental

"Okay, Entoma, Peter, Mare, gather around" Genjiro gestured for everyone to huddle around him

"I'd be more than happy to explain all the chemical processes that you're about to undertake, but It is quite complex and I don't want to be here all day, so I'm just going to give you the rundown on what you need to do."

He looked at their faces and saw that there were no objections.

"The ultimate goal of this exercise is to get a small white crystal called Potassium Nitrate, or if you want to use its archaic name, Saltpeter"

He opened his pocket dimension and pulled out a small metallic sphere labeled "Feces" and handed it to Peter. "I want you to fill the ditch full of straw and feces, and once you're done.." He pulled a second sphere labeled "Urine" and handed it to peter "I want you to moisten it until it is completely saturated with urine"

"After a while it's going to evaporate so keep spraying it with urine to keep it moist, have your skeletal workers continually turn the pile to keep everything mixing well."

"Mare, whenever you have time, come down here and cast a few growth spells, It may speed up decomposition. Peter have your fire elemental constantly keeping the temperature warm, this will quicken evaporation and decomposition"

"This is a process that would normally take around seven months in this kind of climate, but with Mares magic and the fire elemental, I think we can achieve complete saturation in seven days"

"Once seven days have past, or until you notice that decomposition isn't taking place anymore, switch from moistening it with urine, to moistening it with water. This will allow the salts to rise to the top of the bed as the water evaporates"

"After a while you should see a whitish crust appear on the surface. Contact me when this happens"

Genjiro looked around at everyone's faces, they seemed to be focused and deep in thought "Trust me on this, It'll work"

Mare looked up and smiled "Of course! This is coming straight from a supreme being after all!"

Genjiro smiled and nodded, "That's the spirit. Alright get to work you two."

Both of them bowed and went to their separate duties

Mare walked off and started to prepare for a growth spell.

Peter jogged over to where the fire elemental and skeletal workers were and began giving the orders. He put the two spheres he had just been given on the ground and stepped back, suddenly they grew to the size of dump trucks.

Genjiro stood off to the side with Entoma watching this "Oh, you may need this" He reached into his pocket dimension and pulled out two simple looking silver amulets, "This amulet should protect you from the stench"

After putting one on himself, he made a fatherly motion of putting the second amulet around Entoma's neck

"T-Thank you, Genjiro-sama"

Is she blushing? I didn't realise the mask bug could do that. Actually, on second thought, does her arachnid biology even permit her to be disgusted by the smell of feces?

Just then a torrent of chunky brown liquid spewed from a hole in one of the spheres into the ditch and skeletons began shoveling in straw after it. All just more things to be investigated.

Watching the heteromorphs work, he nodded in satisfaction, "They seem to have everything under control here, let's go find Aura for the next stage of the plan"

.

They found Aura in another clearing not too far away from where the saltpeter bed was. She was sitting around a pile of wooden scraps along with the fire elemental, elder lich, and the remaining skeletal workers.

When they saw Genjiro and Entoma approaching they stood up and Genjiro gestured for Aura and the Elder Lich to approach them.

Genjiro looked at the Elder Lich, "Your name is now Charles, glad to have you on the job site"

Charles talked in hollow voice identical to Peter's and bowed "I bow before the supreme one"

Genjiro nodded and began just like how he had done earlier with Peter "Our goal here is simply to make charcoal. But we're going to be making it the right way. This is much simpler than what Peter and the others are doing so I'll give you a quick chemistry lesson"

Genjiro stuck out his hand and extended his finger like a professor giving a lecture "You see, when we burn wood, we're not actually burning the wood itself, but gases given off by the wood when it's subjected to heat. Those gases immediately react with the oxygen in the surrounding air and the result is a flame. What's left behind after that is a useless piece of ashen char"

"So the idea behind charcoal making is not to burn the wood, but to heat enough so that it undergoes pyrolysis. Basically, we're using heat to break certain chemical bonds in the wood so that turns into a much more combustible and useable form."

"However, the temperature required for pyrolysis to take place is very high, and any piece of wood would have long since combusted by then. So then how could we get the wood hot enough without burning it?"

Genjiro looked at the three of them. He couldn't read Charles's face for obvious reasons but Aura and Entoma seemed completely lost by all the words they had never heard before. He couldn't help but feel a little disappointed.

He decided to just get to the point "The answer is to remove all the oxygen. All you have to do is cover up all your wood scraps in a mound of dirt and use the fire elemental to heat it. After you've done this for a while you can remove the dirt and you should see that the wood has turned black and very weak"

"Thats charcoal, that's all we're after. It's okay if a little air gets in, it'll just create a little ash, It's no big deal, we'll have use for those ashes later. Okay, you guys think you can handle it?"

Aura and Charles bowed deeply, "Of course."

Genjiro nodded, "Good, then get to it"

Aura and Charles turned and jogged to their respective duties, Charles to organize the skeletons and fire elemental, and Aura to get the wood from the fortress.

He called out as Aura jogged away "We don't need too much charcoal, any leftover wood scraps from making that huge fortress of yours should be more than enough. Once you're done you can return to your normal duties."

Aura turned and bowed once more "Understood."

Genjiro stood with Entoma and watched Aura's back retreat into the fortress. He then put his hand on Entoma's head.

"Alright, time for stage three of the plan, and the reason why I'm currently in this body."

.

.

It was just past noon and Genjiro and Entoma were nearing Carne Village

Genjiro put his hand on his chest, "Now remember, I'm the traveling scientist and brother of Momon, Zen"

He then moved his hand to on top of Entoma's head "And you are?"

Entoma trotted alongside her creator, happy to be his hand rest "I'm your assistant, Ellie"

"Correct, Ellie dear. Oh, that reminds me, stop here for a second" They stopped on the path and Genjiro took off his grey cloak, revealing the black leather armor he wore underneath.

"Here, take this, It would be bad if too many people saw your face" He extended the cloak towards Entoma

Entoma put her hands up in panic "Wha!? I couldn't possibly do something like wear your cloak!"

The hell girl? It's just a cloak

"Look, it's fine, here" Genjiro took a step toward Entoma and flung the Cloak around her, catching the other side after it wrapped around her. As this was happening, its size changed to match Entoma's height.

"See, It's not going to kill you" He finished tying the front of it together. "I'd say it even looks quite good on you."

"It's true that The Mantle of The Silent Pigeon is one of the better cloak items in YGGDRASIL, but it isn't exactly hard to come by" He pulled an identical looking gray cloak from his pocket dimension and put it on.

"Alright then, let's get a move on, Ellie dear"

"Understood, Zen-sama", Unbeknownst to Genjiro, Entoma was smiling like a school girl underneath her new cloak Aww~ It smells just like Genjiro-sama

After walking up the path a little further, they reached the wooden gates of Carne Village.

A troop of goblins sprang from the brush around them with weapons drawn, "Halt! No one gets into this village without the boss's approval!"

"Do not worry, we mean no harm. I'm Zen, the humble traveling scientist, and this is my assistant, Ellie" Zen put his hands up to show he meant no harm.

"Yea! Well why don't you just wait right there until boss gets her, Mr. Scientist, whatever that is." The goblin made a point of mockingly emphasising the word "scientist".

A female voice came from behind the goblin that was just speaking "You're always so serious and busy-wisy Jugmen-chan ~"

A brown-skinned maid with two long braids of red hair stepped out in front of Jugmen, "I know them. You'd be dead by now if they wanted to hurt you~"

"Good afternoon Lupusregina-san, we're looking for the residence of a Mr. Nfirea Bareare, could you show us the way?" Zen made sure the goblins saw his pleasant smile.

"Of course, right this way, Gen-... Zen-san"

Lupusregina led them into the village much to the chagrin of the goblins, but they knew better than to mess with that sadistic servant of Ainz Ooal Gown.

She led them to a small wooden house with a thatched roof "You'll find Nfi-chan inside~"

"Thank you Lupusergia-san, we'll take it from here"

Lupusregina did a bow out of habit and left them to return to her normal duties.

Zen walked up to the door and was confronted with a very strong scent of medical herbs. If I didn't know any better I'd say we have a pot head on our hands.

He knocked on the door after chuckling silently to himself. There was a sound of locks being undone and the door opened to reveal a young man with light brown bangs long enough to cover his eyes.

"Hello, Mr. Nfirea Bareare I reckon?"

Nfirea talked in a soft voice "Yes"

"Excellent, my name is Zen and this is Ellie, might we have a moment of your time?"

He stood aside and gestured to come in "Yes, please come in and sit anywhere you like."

"Thankyou, this won't take anytime at all." Zen and Ellie sat down on the only couch in the room. After closing the door, Nfirea grabbed a chair out of a storage closet and sat across from them.

"I am what is known as a scientist, you can think of me a a scholar of sorts. I was searching for a talented young alchemist and so my brother Momon sent me here. I'm just here to ask you a few simple questions."

Nfirea nodded trying to internalize everything he just heard, especially now that he knew the person before him was the brother of the great Momon. "Ah! I see your resemblance to Momon, you both have the same foreign looking face."

Seeing this nodded and Zen continued, "Yes, we both come from the same country. First and foremost, have you heard of the word 'Chemistry' before?"

Nfirea racked his brain but couldn't recall any time he had heard the word before, "No, I'm sorry Mr. Zen, it sounds a little bit like 'Alchemy', but I don't remember hearing anyone say it like that."

"Hmm, I see." Zen brought his hand up and rested his jaw on it, "In that case, I'm going to name a series of words. Stop me if you recognize one."

Zen cleared his throat, "Okay then, here I go. Hydrogen, periodic table, atom, gravity, electron, potassium, uranium, quantum physics, nuclear fission, ion exchange, hydrolysis, electricity, triglyceride, cation, anion, gunpowder, dynamite, sulfur..."

Zen stopped when he saw that Nfirea was completely clueless about everything he had just said. Nfirea realized Zen had stopped and put his hands up in apology "U-Um I'm sorry Mr. Zen but I haven't heard of any of those. Maybe a couple of them sound like some spells I've heard mages use before, like "electricity", but I really have no idea about the rest of those."

He bowed in his chair, "I'm sorry I couldn't be of more use to you Mr. Zen"

"No, that's quite alright, I wouldn't have expected you to know much if any of those." Hmmm, so it seems this world really does have no inkling of science

"Alright then, on to another matter."

Zen leaned in a little closer and recalled what he had heard the first day he arrived in the new world, "Do you have anything here that resembles 'stinky yellow brimstone'?"

Nfirea's eyes lit up a little, "H-Hai! Please wait here for a second"

Nfirea disappeared into a back room and re-emerged holding a chalky yellow rock, "You must be talking about Jaunded Brimstone. It isn't very useful for alchemy or really anything for that matter. I like its color though and people like to keep them around as knick knacks." as he was saying this he handed the stone to Zen.

Perfect, this is definitely sulfur, let's hope he knows where to find more of it. "Do you know where I could find more of this 'Jaunded Brimstone'?"

Nfirea looked up like he was trying to remember something "I think it comes from this place right outside of Moot village called the Devil's Maw, I can give you directions if you want."

Jackpot! It seems like I won't have to get sulfur the hard way after all. "Thankyou Nfirea-san, that would be wonderful".

After receiving the directions Zen and Ellie stood up "Oh, one more thing. Do you have any books on alchemy that I can borrow?"

"Of course! Anything for Momon's (and Ainz Ooal Gown's) brother" He disappeared into the back room again and returned holding two worn looking books.

"They're a little worn, but they're good books, I've already memorized all the words on every page" He handed the books to Zen.

"Please have a safe journey you two." Nfirea bowed as Zen and Ellie were leaving through the doorway.

"And you have a good day as well Nfirea-san" Zen said before closing door.

He stood outside with Ellie next to him and then put his hand on her head, "Alright then, next stop, the Devil's Maw"
