Let go of that monster girl!

Two small, light green arms, along with a hammer, were spun around and flung away.

Lem stared blankly down at his empty shoulders.

The rat women burst into laughter.

The foreman rat laughed until tears streamed down her face. She jogged over, picked up the hammer and the two severed arms, and handed them to Lyme, watching as Lyme slowly reattached the arms to his shoulders, allowing them to fuse together.

"Miss Lyme, you should come with me."

Foreman Mouse rummaged through the cabinet and pulled out a red hard hat, then stood on tiptoe and removed the white hat from Lyme's head.

"The one wearing the red hat is the safety officer; just follow me."

Lyme followed behind the foreman rat, weaving through the narrow mine tunnels.

The red hat stood out brightly under the dim glowstone light. The rat girls who were digging on both sides of the mine wall stopped what they were doing, wiped the dust and sweat off their faces with their sleeves, and waved to Lym.

"Miss Lyme, how squeaky!"

"Miss Lyme!"

"Thanks to Miss Lyme's acid, those big rocks were much easier to break after being heated with acid."

"That's right, and there's also the Baron's gunpowder, but it's not enough."

The foreman rat explained things to Lyme as they walked.

“In the past, rats would dig vertically under their feet and then dig out to both sides. This way they could dig quickly and didn’t need any support.”

"But if a mouse slips while climbing up, it will fall for a long time."

"These ventilation fans and hoists were added later by the Baron."

She stood on tiptoe and patted the red hat on Lyme's head.

"Even this red hat was added by the Baron later. If you see a mouse without a helmet, go and pull its tail."

"it is good."

The rat women in the mine were busy as bees, wielding picks to chisel at the rock walls.

The little mouse squatted on the ground, picking up the broken ore pieces one by one and putting them into a basket, then carrying the basket and pouring it into the iron bucket of the mine cart.

The mine cart was full, and four or five mouse girls lined up at the back of the cart, shouting as they pushed it together.

"One, two! One, two, squeak!"

"Make way! Screech! The car's coming!"

The minecart's iron wheels creaked as it rolled past Lyme on the tracks.

The tired rat girls gathered in twos and threes at a slightly wider intersection of mine tunnels and sat down against the rock wall.

The mice took their water bottles off their waists, unscrewed the caps, took out a small sugar cube from their pockets, threw it in, shook it, and took a big gulp.

Some of the mice even started singing loudly.

"Dig, dig, dig, squeak, squeak! Dig up ore, exchange it for sugar, squeak! Big hammer, small hammer, smash it all together, after smashing it, go home and eat sweet treats, squeak, squeak!"

The tune drifted to the neighboring mine tunnel, and soon a shovel slapped the singing mouse girl's buttocks.

"oops!"

Lem blinked.

The one singing seems to be the navigation mouse.

She even had a head of hair that was all messed up from being licked by a dog.

The mining rats had already pushed a whole cart of ore to the hoist. The foreman rat walked around the cart, stood on tiptoe to look at the overflowing copper ore, and made a mark on the stone slab with his stylus.

"The container is full; each mouse in this team will be rewarded with a sugar cube."

"Great!"

The other rat girls in the mine tunnels poked their heads out, watching eagerly.

"They're so fast."

"Hurry up and dig, or all the candy will be gone!"

"Ugh, all the candy I saved up for so long was won by that bad fox."

Exhausted, cramped, dangerous.

But the atmosphere was exceptionally cheerful.

Lyme didn't really understand either.

It was completely different from the slave mines that Lyme had seen before.

"I heard that after this batch of ore was refined, the Baron has some new strange things up his sleeve."

"What is it?"

"It's supposedly a super-sized drill bit, rat-a-tat-tat-tat!"

“Moving these useless stones out can be used to build a ramp for the mine tracks.”

Each mouse's eyes shone with anticipation and hope.

As Lyme left, Foreman Rat stood next to the hoist and waved to her.

"Take care, Miss Lyme! Come visit again next time!"

Lyme sat atop a large truckload of copper ore as the hoist hummed and ascended the shaft.

Fluorite lanterns swept past below one by one, making the mine tunnel brighter and the air clearer.

Finally, they returned to the workshop.

In the very center of the workshop stood a gigantic, absurdly large rat device.

The runic bronze jar was placed on the central base, surrounded by copper and iron pipes of varying thicknesses, winding and connecting, and temporarily secured in several places with wire and nails.

A round gas cylinder was welded to each side of the copper can.

Several pipes extend from the top, leading to a diversion valve hanging from the roof beam. The diversion valve is connected to more pipes, the ends of which are connected to several nozzles.

The nozzle is inserted into a covered copper tank, but no liquid has been added yet.

No two tubes in the entire device are parallel; where the strength is insufficient, the thickness is used to compensate.

The various wires were haphazardly arranged, looking like a pile of metal scraps that had been gnawed by rats.

It's ugly, with a style reminiscent of a low hill.

Several mouse girls were working together to pull a rope, lifting a pumping device, just like the one used in the sour train, from the ground and wobbling as they tried to attach it to the connector on top of the copper can.

"A little to the left!"

"Too left-wing!"

The air pump swayed in the air, while a bunch of blacksmith rats chased after it below.

Lem silently walked behind Moren.

Molen was writing and drawing in his notebook, his eyes fixed on the air pump being hoisted.

He turned to look at Lyme, amused by the little red hat on her head, and casually asked:

"Lyme, what did you see?"

"Rat girls, you've worked so hard."

Lyme answered in a low voice.

Of course, Aishan is a mine.

Such a thing has always been synonymous with arduousness, danger, and a greasy, unpleasant experience in any era.

Lem added another sentence.

"But they were very happy."

Molen nodded in satisfaction.

Little Slime Girl had only seen Mouse Girl on the surface and in the shallow mine tunnels, but the underground mine tunnels were the foundation of the dwarf mountain.

He continued:

"The rats are very good at mining, and they are always happy to do what they are good at."

"Many noble ladies would even drive carriages in their spare time, enjoying the pleasure of dragging a lot of things along."

"But if you pay them to help you carry your luggage, then you're just asking for trouble."

The mouse girls are very hardworking.

People can enjoy hard work.

But it's best not to enjoy being praised for your hard work.

Molen is very lazy.

So he had to be lazy to the point that even the mice could be lazy.

Moren turned back to look at the ugly, large monster that was being banged around by the blacksmith rats.

Chapter 85 Synthesis of Ammonia

Foreman Rat, carrying the stone slab in both hands, trotted up to Morren, stood up straight with his feet together, and loudly reported to Morren:

"Baron! All the rat girls in our class are on duty, and the amount of ore collected exceeds 10000 kilograms. There have been no rat casualties!"

Moren took the stone slab and glanced at it. It was covered with the names of the rat girls, and attendance and special circumstances were marked with an iron pen at the back.

Although plant paper had long been widely available, each sheet still cost about 3 copper coins. The rats wrote their notes on stones, carving long-term notes and scribbling short-term ones.

Morren nodded.

"Well done, each mouse gets an extra candy."

There were about fifty or sixty female rats in the group, led by a foreman rat.

After installing an electric hoist and using acid fire and gunpowder, a shift of rat girls can mine about ten tons of ore in an eight-hour work cycle.

Ten tons, that's not a lot.

Metal ore has an extremely high density; one cubic meter weighs more than four tons, and ten tons is only a little over two cubic meters. A pile of these ore is smaller than the size of the rats themselves.

But if you're talking about few, then there are quite a few.

Moren turned to look at Lyme, who was standing quietly behind him.

"Lyme, a dwarf mountain rat girl can mine 160 kilograms of ore in eight hours. How much ore do you think a beast girl in a slave mine can mine in eighteen hours?"

Lyme stretched out his translucent little finger, counted for a while, and finally held up three fingers.

"360?"

Morren held up one finger.

"10 kilograms, a total of 10 kilograms."

That's why they say science and technology are the primary productive force.

Mining, death, and animal-eared girls.

In the Middle Ages, a miner would dig with deadly intensity all day and produce less than a tenth of what a dwarf mountain rat could produce.

Walking, digging by hand, carrying on shoulders.

Those poorly managed noble ladies often only managed to mine about ten tons of copper ore a year.

Those aristocratic ladies who were good at managing their affairs knew that mining one ton of copper ore required the consumption of one rat girl.

A rat girl worth 3 silver coins can be exchanged for copper ore worth 20 gold coins.

In the Mouse Girl Kingdom, 1 gold coin is equal to 20 silver coins, and everyone knows how to do that.

The slave rat girls of the new market were sent to the north in groups for this very reason.

Dust, poisonous gas, darkness, narrowness.

Plague, collapse, flood, famine.
