Chapter 925

What Su Chen said.

I mean gunpowder.

He has read a lot of otherworldly farming streams, and gunpowder is simply a magical weapon for traversers!

The source of materials is wide, the production process is simple, and the power... In Su Chen's eyes, it can barely be justified - at least it is not a problem to blow up a fully armed knight to pieces.

There are three raw materials for gunpowder, charcoal and saltpeter. sulfur.

As long as you follow the best mix ratio of 15:3:2, you can make it.

Charcoal and sulfur are naturally present, the only thing that is a little troublesome is saltpeter. That is potassium nitrate.

In fact, making nitrate is not troublesome.

Potassium nitrate exists in a large amount in the soil near the pigsty and the toilet, which is rich in organic matter. After these organic matter decay, it will form nitric acid under the action of nitrifying bacteria, and the nitric acid will further react with arsenic, calcium, and magnesium in the soil to form potassium nitrate. and its calcium magnesium nitrate. This is soil salt.

Soil nitrate can be used to make gunpowder, but what is made is black powder, and its power is greatly reduced.

Generally, the crystallization method is used to extract potassium nitrate with a higher concentration.

But now, Su Chen has Aixi, this little girl can directly extract pure nitrate from soil nitrate, without a series of procedures, it's too heaven-defying!

After making up my mind.

Su Chen asked the servants in the castle to buy some sulfur and some charcoal from the cellar for the winter.

Finally, he secretly took Ashe to the toilet of the castle.

"Come on, Ashe, use your ability on the dirt by the wall to see if you can get some white powder."

Su Chen found a white hooded coat for Ai Xi, and at the same time looked around with his golden eyes, making sure that no one would see him.

"let's start."

"Um."

The blue-haired girl nodded and held out her hands. Aim for the dirt under the corner of the toilet wall.

Close your eyes.

The familiar feeling reappeared.

There are countless surging and interlacing light clusters in front of her. With a slight movement of her mind, these light clusters will be separated in an orderly manner, and a series of mysterious changes will occur.

"Okay, that's fine."

Su Chen's gentle but slightly embarrassed voice came.

Ashe opened her eyes.

She broke down a big hole in the wall of the toilet, and all kinds of gray-black powder and viscous liquid were piled up on the ground, causing Su Chen a headache.

"It seems that some of them have to be dug out and separated separately."

He sighed.

Ashe bit her lip. "...Brother Su, am I not doing well?"

"It's okay, you have just awakened your ability, it's normal that you can't control it well."

"Just a little more practice."

Su Chen turned his head and stretched out his hand, caressing the hair on top of her head a few times, "You must remember, this is not the power of a devil, but the power to contribute to changing the world."

"Um!"

Although she didn't understand the meaning, the little girl nodded vigorously.

At the same time, she lowered her pretty red face.

subsequently.

Su Chen took out an engineering shovel from the ring. A lot of soil was dug around the corner of the toilet and put into a snakeskin bag.

Then he brought Ashe to an attic at the highest point of the castle.

Few people come here, it is a good place to do experiments.

"Come on, try again."

Su Chen poured the pungent-smelling soil out of the bag. piled on the ground.

If it was a lady from an ordinary aristocratic family, she would definitely not be able to bear this smell, and would definitely run away holding her nose.

But Aixi was born in a slum, so she has basically no sense of this smell.

Straight out two pieces of porcelain white hands, displaying the ability——

"Hey, huh."

"Hey, huh."

Some sounds like shaking chaff sieve came.

soon.

The soil piled on the stone slab gradually divided into several piles as if being fiddled with by a pair of big hands.

A large amount of pure soil, various mineral particles. Microbiome, and some moisture.

Su Chen's gaze was like a torch, and he quickly searched for saltpeter inside.

"I...I can't do it!"

"Ahhhhhhhh..."

Ashe decomposed and purified a bag of nitrate soil. He was out of breath, his face was pale, and the magic power in his body was almost exhausted.

Su Chen came over. Patted her on the shoulder, "Are you all right?"

"It's okay, just... just, very tired!"

Ashe propped her hands on her knees, panting heavily.

Looking at the remaining four big snakeskin bags of dirt, she showed a trace of shame on her pretty face: "I'm sorry, Brother Su, I'm so useless."

"Normal, it's already amazing to be able to do this for the first time."

Su Chen smiled and encouraged.

Ashe looked around and saw dozens of piles of various substances on the floor of the attic. Dazzling to see.

"Brother Su asked me to decompose this soil for what?"

"really weird……"

Ashe sat on the spot to rest, with a puzzled expression on her face.

Su Chen took out a bottle of Kang Shuaifu mineral water from the ring, handed it to Ai Xi, then walked to the piles of materials, looking around, looking for something.

"Well!"

"So sweet!"

Ashe grew up drinking river water. When I drank mineral water for the first time, I immediately fell in love with the pure taste.

at the same time.

Su Chen squatted beside a pile of white cotton-like powder.

He squatted down, put his finger on the tip of his tongue, and a bitter taste came along with a slight tingling sensation.

Then he snapped his fingers again, calling out a cluster of flames, burning some white powder, and observing the reaction of the flames.

After seeing the purple flames and smoke, he nodded in satisfaction.

This is what he wants.

saltpeter.

Immediately put this pile of saltpeter into the ring.

Afterwards, after Ash finished her rest, he asked her to decompose and purify a bag of nitrate soil.

This time, the little girl was completely squeezed dry, her limbs were limp as mud, and she couldn't stand up anymore.

Su Chen couldn't force her, so he took her back to her room on the fifth floor to rest, and at the same time asked the servant to bring some pastries and tea.

Under normal circumstances, servants would not dare to break in suddenly, so Su Chen was assured that Ai Xi would stay inside.

However, living under the fence is always troublesome.

Su Chen plans to buy a house in Mithril City in a few days, and then put Ai Xi there, so that nothing will go wrong.

As for the Marquis Mansion bestowed by His Majesty the King, it is still being repaired and will be available for occupancy after a while.

A few minutes later.

In the corridor of the backyard of the main castle.

An elderly servant found Su Chen.

"Master Marquis, I have found the charcoal and sulfur you asked for."

"Quick! Bring it to Lord Marquis."

The older servant beckoned, and there were a few servants doing chores behind them, carrying four large coarse bags, and put them in front of Su Chen with difficulty.

Su Chen opened the mouth of the bag and took a look.

Half of it was black and thick charcoal, and the other half was light yellow powder. These servants moved really fast.

"Thanks for your hard work."

Su Chen casually threw a few golden eagles over, telling them not to tell Galen and Lacus.

The servants all smiled, nodded and left.

"God!"

"Six golden eagles!"

"Master Marquis is really generous!"

"That's it, my uncle, but the Marquis of Lucifer personally appointed by His Majesty the King, it's amazing!"

"Totally worthy of Her Majesty Lux!"
