My Post-Apocalyptic Shelter Levels Up Infinitely! - Chapter 76

[Chapter 76 Magical saltpeter in exchange for information!]

【Saltpeter (sophisticated)】

Description: The high-purity saltpeter purified by the entry-level artisan “Suma” has a wide range of functions and can be used to make matches, pyrotechnic powder, black powder, glass and food preservatives. For inexplicable reasons, the grade has been upgraded to the excellent level.

Special ability: Make nitric acid (concentration (95%↑)

make gunpowder (energy +50%)

make explosives (energy +50%)

Evaluation: many uses, wide range, quick effect! Is it just hanging? Yan!)

The property page popped up by the system is the first time to be swiped by the special ability of saltpeter.

There are more than 30 uses in various aspects, and they have been strengthened to a certain extent.

But this is not what surprised Sumo the most. ”

It turns out that when the nether energy water is mixed with these things, there will be so many changes?”

Surprisingly fiddled with the saltpeter in the beaker, Sumo still couldn’t see how this thing had so many characteristics.

“But ”

If the system is so powerful, I’m afraid my technology tree will skyrocket!”

Staring at the saltpeter powder, Soma’s thoughts have drifted to the oil well in Refuge No. 2.

Originally this wave After purifying saltpeter and sulphur, and mixing charcoal, the famous black powder can be produced, which directly enters the age of firearms.

But now, an abrupt term pops up in Soma’s mind –

“bitter acid!”

As the famous “” Yellow dynamite” (TNP), also known as “picric acid dynamite”.

Its composition is “trinitrophenol”, which is often confused with Nobel’s “safety dynamite”, “TNT”.

In 1771, Englishman Peter Wolfe synthesized a dye.

He mixed concentrated sulfuric acid, nitric acid and phenol (probably refined coal tar crude phenol or indigo, phenol was not known at the time), and obtained a bright yellow crystalline powder with a strong bitter taste, so it was Given the name “picric acid”.

At that time, people just dyed clothes with bitter acid and made paint.

In the dye world at the time, the name of trinitrophenol was often “yellow”, and people had dyed fabrics with bitter acid for 100 years, but never thought about how to fry it.

In 1871, the guys in a dye shop in Paris, France, encountered a problem. There was a backlog of yellow dye cans that seemed to be rusted and could not be opened no matter what, so the eager guys decided to use the simplest and rude method to open the cans— – Smash!

And the hammer he found was a big hammer for 80 yuan.

This time, the hammersmith made all his strength and went down with a hammer!

Unexpectedly, the jar exploded with a “boom”, and the entire dyehouse immediately took a dirt plane, leaving only a group of colorful survivors moaning in the ruins.

After multiple investigations, people ruled out the factor of unidentified explosives hidden in the jar, and locked the problem on the picric acid jar, and people suddenly realized –

“The yellow pigment was detonated by hammering!!!”

This matter is in the society. It caused a stir, and people were worried about the “yellow color”.

But the French military at the time was bright. This was obviously the best military weapon sent by God. The “yellow color” proved its safety in long-term use, and it can also be easily prepared on a large scale.

Then the French “Eugene Turpin” took the lead in developing the “picric acid pressing method” for shells, and gave it the name of “Mai Ning Dynamite”, that is, “melinite”.

This term is unfamiliar to many people, but everyone is familiar with the 1897-type 75mm field gun, which is Li Yunlong’s “Italian gun”

Now, there is saltpeter to prepare nitric acid, and sulfur and saltpeter can react to generate sulfuric acid, and then add some oil to extract the toluene inside.

“If it is really possible, I am afraid that my bomb technology tree will directly go beyond black gunpowder, nitrified cotton wool, and come directly. To the era of yellow dynamite!”

Thinking about the configuration of dynamite that Dad had been talking about before he came, Soma instantly became excited.

After all, black gunpowder is only propellant, and when it is made into a gunpowder pack, it can only complete the two processes of detonation and combustion.

Different from picric acid, once the shock wave with chemical reaction is detonated, an explosion reaction occurs at the detonation point to generate a large amount of high-temperature, high-pressure and high-speed airflow, which excites the shock wave in the explosive.

The shock wave strongly compresses the adjacent explosive thin layer to cause the explosive reaction, generating a large amount of gas and a large amount of heat to complete the process of detonation-bombing-wave.

Even if you can accumulate enough picric acid, make it into a dynamite bag and throw it into the kobold castle.

Under the detonation wave, as long as one back and forth, the kobold can know what justice is from the sky!

“I’ll try to repair the oil well tomorrow!”

In front of the workbench, Soma stood up and sat down again and again, his inner agitation was hard to calm down.

Pour the purified 500g saltpeter powder into a wooden container and put it in the second bedroom. Soma returned to the workbench again.

“I know the formula for purifying yellow explosives. I have also learned the methods of preparing nitric acid and sulfuric acid in high school. These are not problems. The key lies in the process of extracting toluene in petroleum and the process of mixing and reacting to generate picric acid.”

“Nobel made explosives back then. He killed his younger brother. Although this picric acid is not as difficult as nitroglycerin, it may explode when it encounters high temperature, friction and impact, and it can react with iron, like mercury fulminate to form mercury salt. Generate picric acid metal salt, causing accident and explosion danger”

“Maybe I can get the preparation method of picric acid through transaction intelligence, and get a better and safer way through system upgrade!”

Having figured this out, Su Mo did not hesitate to call out the game panel to find a contact person.

After swiping through all the friend lists, Su Mo finally focused on the line marked Shen Ke.

Focus, open the chat panel.

[Su Mo: Hello Shen Ke, do you have time to chat? I want to make a deal! 】

After the news was passed, Soma continued to sit in front of the workbench and waited quietly.

Sure enough, after less than five seconds, the video of Shen Ke on the opposite side popped up.

When the video was connected, the screen squeaked, and Shen Ke’s slightly tired pretty face appeared on the screen.

“Wow, Mr. Soma, your shelter is developing so fast, it doesn’t look like a wasteland at all, but a bit like the brick house of my hometown!”

Bright lights.

Clean and tidy partitions.

In the distance from the camera, the big and small sparks and Oreos are still playing on the ground.

Looking at myself.

The dilapidated wooden house was still lit with homemade smoke torches, and it was pitch black through the window.

From time to time, a headwind blows, blowing black smoke into the room, causing people to cough.

“Where, I’m also lucky, I made some achievements, and it’s not worth mentioning compared to you.” With a wave of his hand, Soma quickly ended the courtesy time and went straight to the topic.

“I want to make a deal with you. Yellow dynamite, you know, is picric acid. I think some of you should know the formula and preparation method?”

“I know, this is not a problem, if it is not enough raw materials, we It’s all made, do you have any ingredients near you?” Shen Ke said it without further thinking.

After all, this thing is not difficult, compared to the following tnt and black suojin or cloud bombs, as long as there are raw materials for yellow explosives, there is basically no difficulty.

But what this thing lacks is the raw material!

Back then, Guhuaxia failed to develop explosives, and the reason was that oil was difficult to exploit.

Not all places have petroleum. As a top-level strategic material, it is obvious that there is no exploration near Shen Ke’s shelter.

“Cough, this ingredient, I opened it from the treasure chest, and I just want to make some explosives for self-defense because I have a little storage now

.”

However, there is no need to explain too much, everyone is just trading, so far.

On the opposite side, Shen Ke nodded: “What about the trade item this time? Is it still nether energy water?”

“No, this time I will exchange the information with you, there is information about alien creatures!” Sumo smiled confidently, posing wave.

“This. I’m afraid I can’t be the master. I need to ask the above for instructions.” Shen Ke was embarrassed, and after receiving Soma’s answer, he hung up the phone.

After a while, when the phone was connected again, there were two middle-aged men with dignified faces sitting across from them. There were also four recorders sitting behind the men, looking nervously at the camera.

“Hello, Soma, we have passed your transaction. You just need to tell us the information about otherworldly creatures. Whether we know it or not, we will give you the complete recipe and preparation method afterwards.”

Nodding, Soma did not Afraid of running away from the opposite side, he bluntly told the information about the warrior kobold, the warlock kobold, and the white-robed kobold who hadn’t figured it out yet.

In the process, Soma concealed some details of the battle, and only told the spellcasting method of the warlock kobold, the combat power of the warrior kobold, and the information that the kobold brought supplies when he came.

The four recorders worked hard to write, and Soma could observe from the video the shock on their faces as more and more information came out.

Even the serious middle-aged man sitting on the left asked several details over and over again during the process.

“Okay, Soma, thank you for your contribution to mankind. Your information is very useful. This information will be gradually distributed to the Huaxia Refuge. Do you have any opinion on this?”

“No no.” After speaking, a few People hurriedly stood up, and Shen Ke sat back again.

While the other side was preparing for bitter and sour, the two also began to chat with each other.

“By the way, Shen Ke, what’s the identity of the person sitting on the right just now? It feels a little weird.” After changing the topic for a few waves, Su Mo changed the subject and asked the doubts just now.

The man on the left was vigorous and resolute, sitting upright, while the man on the right was still a little bit at first, but after a few minutes he sat loosely.

“The biggest doubt is that when I mentioned the kobold information just now, although he looked shocked, his micro-expression seemed to be already known.”

“Oh? You said President Ying? Ying Tianlong He is the president of the folk self-rescue association, and their family is relatively large. When they came here, more than 20 people were thrown together, and he is the main force of our “tundra” refuge!” Shen Ke smiled naively, without concealing it. said.

“Tunda?”

“Well! This is the name of our refuge. Of course, if we can get the first disaster resistance next time, we will still use the name Huaxia. This title can only be used by the number one refuge. Other times We all call it tundra.”

“Is that so?” After getting the news he wanted, Soma immediately changed the subject and talked about some aspects of life.

After a while, Shen Ke’s trade request bounced.

Looking at the flow chart of the yellow explosives in the transaction items, Soma smiled under the light.

In a flash of light, two sheets of paper filled with words appeared in front of the work table!

Dear readers! Happy weekend duck! Hahahahaha~
