Chapter 60 Extraordinary Means
Back in the small courtyard, Li Anxian finally had time to think about his own affairs.

The raw materials that Du Hu helped to buy are still piled up in his hut, but within a dozen days, most of them are no longer needed.

When mentioning this matter, Li Anxian was not usually depressed.

Copper blue in this world is bile vitriol; pyrite is pyrite. His original idea was to prepare sulfuric acid by calcining these two things, then use sulfuric acid and saltpeter to obtain nitric acid, and finally soak cotton to obtain nitrated gunwool and press it into tablets Cutting is smokeless pellet gunpowder.

As for the primer, there is no way to solve it for the time being. Let's get the gunpowder out first.

But after being promoted to the fourth level, his spiritual consciousness improved a little, and he recalled carefully when he had nothing to do, and he remembered a lot of the chemical knowledge that he had given back a long time ago.

As a result, Li Anxian found that this method was not only time-consuming, but also made many detours!

What is nitric acid?Isn't it the result of the reaction between nitrogen dioxide and water?It can be regarded as an aqueous solution of nitrogen dioxide!

It is too simple to prepare nitrogen dioxide, isn't it just the lightning that breaks through the air?
Li Anxian can't create lightning for the time being, but the arc should have some effect, right?

So, he completely overturned the original plan and re-formulated a new plan.

He had already made a lot of preparations and refined a batch of glassware in advance.

The ones that can be used are kept for use, and the ones that cannot be used are re-melted. In a few days, the beakers, flasks and various glass accessories needed for the experiment are collected.

He doesn't know how to fire glass, but this problem is easy to solve, just heat up a batch of crystals and shape them.

For the sake of safety, he didn't dare to put the experiment site in his own room, but set up an array in the corner of the small courtyard, carefully connecting the required glassware, and when everything was ready, he excitedly found Dongfang Heron.

The owner of Dongfanglu Pavilion had already changed out of his strong attire. He didn't know what Li Anxian wanted to do, but he was dragged into a corner by Li Anxian purely out of curiosity.

This kid often does amazing things, he has long been used to it, and he is also looking forward to the new gadgets that Li Anxian will come up with.

In case of inspiration, and epiphany!

However, Li Anxian's actions were far beyond his expectations - this kid put a pair of curved copper electrodes in a sealed crystal barrel, and then energized the electrodes through a transformer, and a winding and zigzag line appeared between the electrodes immediately. arc.

Dongfang Heron's face is black, why don't you just show me this?

Although he didn't practice Leifa, he had never eaten pork, and he always saw pigs running. He watched a lot of them on weekdays, and he had already grasped that bit of electrical knowledge clearly.

However, there was no obvious change in the crystal bucket, Dongfang Lu looked at Li Anxian suspiciously: "What are you doing?"

Li Anxian's face turned even darker, and he thought he couldn't. Lightning produced a large amount of nitrogen dioxide, and it was nitrogen fertilizer that fell with the rain. He was confident that he would never remember it wrong.

Exactly which step went wrong?
Li Anxian, who didn't believe in evil, increased the output, raising both the voltage and current to the current acceptable limit.

After waiting patiently for half a minute, a slight change finally appeared in the airtight crystal barrel. The originally colorless gas gradually appeared a little yellow.

As the experiment progressed, the yellow became deeper and deeper, gradually turning a little brown.

Dongfang Lu's eyes widened: "What is this?" There was nothing, why did it suddenly change color?And this thing gave him a very familiar feeling, as if he had seen it somewhere before!

After successfully extracting the nitrogen dioxide, Li Anxian stopped the experiment with a smile: "Dare to ask Master, do you see the extra gas?"

Dongfang Lu nodded: "I see clearly, what's the matter?"

Li Anxian smiled even more happily: "I don't know if Master Uncle can refine this thing?"

"Ah?" Dongfang Lu was stunned, "My boy, are you waiting for me here?"

"There's no other way!" Li Anxian smiled brighter, his eyes full of anticipation.

At first, he really planned to use scientific methods to make smokeless gunpowder, but after thinking about it, this is the world of cultivating immortals. The monks are just obsessed with cultivating and have no interest in researching things other than cultivating, not because their methods are inferior to scientists.

It is no exaggeration to say that many chemical experiments require extremely harsh conditions, but in the hands of monks, it is just a matter of moving fingers.

His brain has never been kicked by a donkey. Since there are such convenient conditions, why not use them?

Therefore, Li Anxian decided to only conduct experiments, and after letting Dongfang Lu know what he needed, he wanted to produce a large amount of what he needed through practice.

When there is nitric acid, then make nitrated gun cotton and show it to Dongfang Lu. Maybe he can make a lot of it with a wave of his hand!
Dongfang Lu thought for a while and said, "It shouldn't be a problem, but we have to think about how to do it!"

"Don't think about it!" Li Anxian was waiting for these words, and he immediately gave his own answer: use high-temperature-resistant metal to make a closed container, fill it with air by means of cultivating immortals, form a high-pressure environment, and then energize it under high-temperature conditions.

To put it simply, it is to use high temperature and high pressure to improve the efficiency of discharging nitrogen dioxide.

After all, he doesn't need 01:30.

Comrade Xiao Li beamed with joy and foamed at the mouth.

Dongfang Lu was confused and didn't know what to say, and finally got really impatient, and quickly interrupted with a wave: "No, you have said so much, what exactly do you want?"

"That's the thing!" Li Anxian pointed to the discolored gas in the bottle.

"Then what do you want this thing for?" After getting along for more than a year, he already knew that no matter what he did, this kid liked to go around in circles.

This question really hit the point, Li Anxian smiled embarrassedly: "I just want to make something."

Dongfang Lu sighed: "What to do, just say it!"

"Gunpowder is a kind of powder that can burn. After it is ignited, the gas produced instantly expands by more than [-] times, at least [-] times!"

Dongfang Lu knew what gas meant, and immediately grasped the key point: "Expanded ten thousand times, right? If you said otherwise, it would be over!"

Li Anxian was a little dazed, what does this mean?
Dongfang Lu took out a blank piece of talisman paper, drew with his fingertips in the air, and laid down layers of restrictions. There was no trace of ink on the paper, but within a very short period of time, it was refined into a magic talisman.

A gust of wind suddenly blew around the body around the talisman paper, and it seemed that a large amount of air was poured into the talisman paper.

Li Anxian's heart trembled inexplicably: "What is this?"

"Wind talisman, no name." Dongfang Lu said, "Draw it according to your requirements, both true energy and spiritual consciousness can be activated, and it will expand ten thousand times immediately, at least ten thousand times!"

Li Anxian's whole body was not well, his eyes darkened, and he almost fainted on the spot.

impossible?This is not true, is it?ah?
