Let go of that monster girl!

The mouse girls possess excellent hearing and strong disease resistance.

It has cheat-like resistance to poison, a petite figure, and super reproductive ability.

There is a reason for all of this.

Well, of course.

In Morren's opinion, using the Rat Girl like this was a complete waste of her talents.

He withdrew his finger and turned to look at the huge, ugly thing in the center of the workshop.

The blacksmith rats had finished welding the last few joints and were now carrying water jugs to pour water onto each seam.

Squat down and put your round ear to the tube to listen carefully for any hissing or leaking sounds.

A blacksmith mouse drew a round smiley face next to a qualified joint with chalk, and soon all the joints were covered with stick figure mouse girls.

Molen patted Lyme's helmet.

"How many times do you think the rat girls' mining efficiency will increase with this ugly thing?"

Lem thought for a moment, then held up one finger, as if she felt that was already a very large number:

"Twenty-five times?"

Morren held up three fingers.

"More than 30000 times."

What does it mean to cheat?

What kind of cheat is it to painstakingly stack up a 20% increase?

The efficiency of ammonia synthesis is 1000000 times that of natural nitrogen fixation!

One ton of fertilizer can directly increase crop yield by ten tons.

When processed into chicken feed and fed to broiler chickens, they gain a ton of meat for every ton of feed they eat, an efficiency even more astonishing than chickens with six wings and four legs in the new market.

That's just how the world is; you can fill in whatever coefficients you want, without any regard for game balance.

Science unlocks new possibilities, starting with Molen.

The blacksmith rats, wiping the grease from their hands, trotted over and stood in a neat row before Morren, earnestly reporting:

"Your Excellency, we are ready and can be activated at any time!"

Molen waved his hand.

"Power on!"

The valve is turned open, and the knife gate is closed.

The huge, ugly device emitted a hissing sound of airflow, the gas in the pipes began to flow, and the patterns on the runic bronze can glowed with a dark red fluorescence.

The rat girls all hid behind Morren.

Molen stood at the front, arms crossed.

A person, a slime, and a group of rats stood about twenty meters away from the device.

Various clanging and rattling sounds emanated from inside the device, and occasionally a small plume of white steam would shoot out of the pipe, followed by a gurgling and sizzling sound.

The mice waited cautiously.

Waiting for this strange device to explode.

After waiting for a long time, this bizarrely huge mountain of metal waste was still running smoothly, showing no sign of exploding into a flower.

"This time, there wasn't a single explosion!"

"It doesn't seem as scary as the rats."

"If it didn't ignite, did it really start?"

The rat girls peeked out from behind Moren, warily watching the large, strange thing that occasionally trembled slightly.

Indeed, compared to mercuric fulminate that explodes at the slightest touch, ice crystals that burn to thousands of degrees and resemble magma, and airships that can create mushroom clouds with a single spark, there are far superior options.

The Haber ammonia plant is just too gentle.

Even if it explodes, it will probably only fly a dozen meters away, which is considered to be exceptionally weak among the many rat-like creatures in the low hills.

It doesn't even emit toxic gases, which is truly touching.

The principle of chemical ammonia synthesis is very simple.

By mixing inexpensive hydrogen with free nitrogen in the air, a very simple chemical reaction can be carried out to produce ammonia.

Then, by passing ammonia gas into nitric acid, ammonium nitrate can be obtained very easily.

If you bury ammonium nitrate in the soil, it becomes fertilizer; if you mix it with gasoline, it becomes ammonium nitrate explosive.

You have now fully mastered it.

Go and refine fertilizer and high explosives!

The principle is very simple, but the values ​​are just too high.

It requires a high temperature of 500 degrees Celsius, a pressure of 20 atmospheres, and catalysis by iron black ore powder.

Coincidentally, all the low hills have them.

The pressurization device is readily available; you can use the one from the acid train.

20 atmospheres of pressure isn't that high. A Coke bottle can withstand 14 atmospheres of pressure. Using a rune barrel is completely overkill. Just coat it with some slime to prevent hydrogen embrittlement.

500 degrees is not even half the height of the blacksmith rat's furnace.

Simply allow the mixed gas to flow out of the device temporarily for cooling. Since ammonia liquefies at room temperature under eight atmospheres of pressure, separating it is not difficult.

Even on Earth, only a handful of countries possess the technology to synthesize ammonia, and more than half of the production comes from four mysterious nations.

This thing consumes a huge amount of energy; either you need to have oil in your home, or you have to build it on a hydroelectric dam.

Coincidentally, there is also a hydroelectric dam on Aishan.

Before we knew it, all the pieces of the puzzle had been put together.

Moren looked at Lyme and the rats, and said with a smile:

"Ladies and gentlemen, I will now demonstrate for you."

"How can a single rat girl produce the equivalent of fifty years' worth of output from an ordinary mine in just one day?"

Chapter 86 Five Hundred Tons of Ore a Day

Several days later, in the wasteland outside the low hills.

The miner squatted on the ground, wearing thick leather gloves, holding a copper pot in its two little hands, and carefully unscrewed the lid.

She turned the jar upside down, and a sticky, opaque, white-green gel slid out.

It lay limply on the ground, with a small bag of quicklime wrapped in cloth lying next to it.

The mine rat picked up the gel, squeezed it with both hands, and found it to be soft and bouncy.

She sculpted a square one, and then a round one.

Finally, he carefully sculpted an ugly doll in human shape, with a big head, a small body, and arms that were different lengths.

She turned around and showed it to the foreman, grinning foolishly.

“Look, Your Excellency.”

Snapped.

The foreman slapped her hard hat, so hard it covered her nose.

"Don't play with bombs!"

"Squeak!"

The miner shrank its neck and quickly put the gel ball back.

In the distance, the rat women stood in a circle, holding hammers and wheelbarrows, a good forty or fifty meters away from the mine entrance.

"Is that sticky, soft thing really a bomb?"

"Yes, it was made by the Baron using the white powder he made a few days ago, mixed with dehydrated acidic liquid."

"The Baron said it's called ammonium explosive, and it's extremely powerful, dozens of times more powerful than black powder."

"Just a small piece, about the size of a fist, shattered the large rock in an instant!"

The foreman rat turned around to face the miner rat, hands on his hips, looking serious:

"The Baron has already set the amount and location of the explosive charge each time. Once the detonation device is set up, run! This thing is no joke."

"All right……"

The mine rat closed the lid, held it in both hands, and took its short legs toward the mine entrance not far away.

The mice's eyes all followed her movement, and dozens of pairs of round ears turned in unison.

The entrance to the mine was dug in the wasteland not far from the low hill, surrounded by barren, dark rocky ground, without any dead trees or buildings.

The Baron said that this new excavation method was too noisy and might collapse the hill, so it could only be left outside.

The surrounding militia rats, spears in hand, stood guard behind the cannons, vigilantly scanning the dark corners of the wasteland, wary of the wandering chimeras.

The mine rat carried the jar into the mine entrance.

This mine is completely different from other mines inside the low mountain.

It was wide and straight, with only one passage that extended diagonally downwards without any branches.

It bypassed the iron ore vein from below and went directly under the vein.

The surrounding mine tunnel walls were square, grayish-white, and smooth and flat, unlike the rough burrows dug by rats.

It was made of hard limestone, poured from a mixture of cement, wood, and iron rods prepared by the Baron and his rats, with a grid inside.

Even artillery shells couldn't damage it.

The mine rat, alone, carried a jar and walked down the minecart track, its fluorite lantern swaying from its waist.

Her own footsteps echoed in the empty slope, pattering.

The deeper you go, the darker it gets.

The miner rat began to feel a little scared.

The slope gradually became gentler.

She looked up and saw a deep hole opened in the limestone roof above, leading straight up to the iron ore vein directly above.

Directly below the entrance to the cave, there was an oversized mining cart parked.

This mine car is ten times the size of a regular mine car, with a bucket made of fungus wood nails and a reinforced frame made of iron plates.

Every seam was riveted with iron nails, making it look exceptionally sturdy.

The mine rat looked up at the dark hole above, swallowed hard, and twitched its round ears twice.

A long wooden ladder leans against the wall of the mine tunnel, extending from the mine cart all the way into the tunnel entrance.

The mine rat put the jar into its satchel, climbed to the top, and opened the jar.

They took out the white-green gel that was no longer recognizable as a doll and stuffed it into the large hole in the rock wall, pressing it firmly inside.

Then she took a wind-up timer out of her handbag.

Is it really possible for even a small piece of this thing to blast apart a large rock?

The miner rat looked at the white-green lump that she had just squeezed into an ugly doll, and her chest pounded.

This place is so big.

She turned the butterfly handle of the wind-up mechanism all the way up, the spring making a clicking sound, and then plunged it into the white and green block.

Shashashasha.

The clockwork started moving.

The mine rat let go, and it slid down the ladder, almost falling into the large mine cart.
