The short videos I watched are from ancient times, and the ancients broke the defense

In the sky.

When the content proceeds to a detailed analysis of the gunpowder configuration method.

The video also thoughtfully shows a demonstration of the power of gunpowder.

Although compared with the power of modern weapons such as tanks and guns.

The lethality of black powder is still very insufficient. but...

How could the ancients understand this?

Something that will also explode.

Isn’t that the gun of later generations?

For a while.

Every dynasty and every generation.

All the ancients were shocked!

They couldn't believe their eyes!

"gunpowder? Is this actually the gun method of later generations?"

"Tianmu actually wants to teach us how to make such a sharp weapon?"

"Be good! The descendants are so cruel! In order to assassinate the emperor, he even taught such things. Is this something ordinary people can see?"

"Ah this......"

"Why are you standing there? Write it down quickly!"

"are you crazy? Do you dare to remember this kind of thing? Did your Nine Clan pick it up?"

"hiss!!!"

The ancients were inexplicably shocked.

A hypothesis of assassinating the emperor was shocking enough.

But now, future generations will actually announce the method of making gunpowder?

Shouldn't this be forbidden?

It should not be accessible to ordinary people. Something?

Why does it seem like everyone can talk about it in later generations?

For a while, everyone couldn't believe it.

And in the sky screen, about how to prepare black gunpowder in ancient times.

It also started to show.

Sky screen:

【my country is the first country to invent and use black gunpowder】

【However, the production of black powder is not very popular.】

【Children who have studied chemistry all know about monosulfide, dinitrate, and charcoal, but do you know where these raw materials come from? How is this one, two, and three ratio matched?】

【In fact, the principle of black powder is very simple. Let’s explain it in detail.】

【First of all, sulfur refers to sulfur in ancient times. Be careful not to confuse it with realgar.】

【Sulfur is not difficult to obtain. Sulfur powder was sold in ancient Chinese medicine pharmacies. In traditional Chinese medicine, it has the effect of clearing away heat and detoxifying.】

【And if you want to produce in large quantities, you can go around the volcano, and maybe you can find natural sulfur mines.】

【The crystals of sulfur are needle-shaped and need to be carefully ground into powder. 】

Datang plane.

When I saw that one of the raw materials for making gunpowder turned out to be sulfur.

Li Er suddenly felt a little incredible

"sulfur?"27

"Isn't this just a medicinal material?"

"Can it be used as a weapon?"

Li Er was surprised.

He was also a little shocked!

The imagination of future generations is unconstrained.......

It’s simply sky-breaking!

It turns out that the method of weapon development can be found from medicinal materials.

How terrible!

【Secondly, saltpeter refers to saltpeter. Its main component is potassium nitrate, which is a colorless or white crystal.】

【In ancient times, there were saltpeter mines that could be mined.】

【The rich or nobles took advantage of the principle that potassium nitrate dissolved in water can absorb heat and took ice in the summer to cool down.】

【Potassium nitrate can also be recycled and used repeatedly】

【Since potassium nitrate will decompose to produce oxygen at more than 300 degrees, it also needs to be carefully ground into powder.】

【As for charcoal, everyone is more familiar with it.】

【This is a raw material that can be found almost everywhere】

【Okay, these are the three raw materials needed to make gunpowder. Isn’t it very simple? 】

After reading the introduction of the other two raw materials.

Li Er couldn't help it immediately. he asked

"Auxiliary machine, I must have heard it correctly, right?"

"Raw materials that are so simple and can be found everywhere can actually make weapons for future generations?"

Rationally speaking.

Li Er is very willing to miss something.

After all, this thing......

It’s so ubiquitous!

Not to mention sulfur.

There are plenty of them in pharmacies.

Not to mention charcoal.

Who in every household does not have charcoal?

And that saltpeter......

Ordinary people may not have it.

But everyone present.

Who doesn’t have an ice cellar at home?

Who doesn’t use saltpeter to make ice in summer?

Just three things.

Can he actually develop a powerful weapon for future generations?

Is this world too crazy?

Still me......Too ignorant?

Li Er was shocked beyond measure.

Changsun Wuji was also stunned.

I couldn't come back to my senses for a long time.

Seeing Li Er's constipated expression.

He sighed quietly

"Your Majesty, since Tianmu has said so, then......Can there still be a holiday?"

Hearing this,

Li Eryi was startled.

【Now that the raw materials have been introduced, all you need to do is grind them into powder and mix them directly.】

【Notice! Be sure to pay attention to proportions!】

【I want monosulfide, dinitrate, and charcoal!】

【The one, two, three here does not refer to the relationship between mass, but the relationship between the quantities of matter.】

【According to the chemical equation, its mass ratio should be 32:202:36】

【In the actual mixing process, the impurities in various raw materials must also be considered and adjusted.】

【In fact, black powder prepared according to the proportion of chemical equations reacts fully, has strong explosive power, and generates the highest amount of heat.】

【When black powder explodes, a large amount of smoke is produced. Its component is potassium sulfide.】

【It is because of this smoke that the practicality of black powder is greatly reduced.】

【If we ignite black powder in a small space, we can make explosives】

【There are more ways to do this. You can roll up paper into firecrackers like firecrackers, or you can put them in bamboo tubes and use fuses to detonate them. You can open roads in mountains and fry fish in water.】

【The above is how to make black powder】

【With the magical attack of black gunpowder, our success rate in assassinating the emperor will be doubled.】

【However, it should be noted that this method was best used before the Ming Dynasty, and the optimal situation was before the late Tang Dynasty.】

【Because the use of black powder in military affairs began in the Middle and Late Tang Dynasties】

【The Ming Dynasty was already the peak of black powder】

【If you wanted to use gunpowder to assassinate the emperor in the Ming Dynasty, you would need to make more powerful modern gunpowder】

【Okay, that’s the end of this video. I wish you success in assassinating the emperor.】

——"If black powder is used by chemists to travel through time, that is, just use it for the first month, it definitely does not need to be used on a large scale, or even very pure. The main reason is that the raw materials are convenient and can be obtained in pharmacies. It really wants to show off. Three acids and two bases, just click on the skill tree!"

——"You can just use smokeless gunpowder, which is more powerful [dog head]]"

——"My big one, let me tell you! Regarding the formula, it is probably 75.10.15, but you have to know that it needs to be adjusted due to different uses. Potassium nitrate: saltpeter and solid oxygen help with combustion. Sulfur: Sulfur, flammable substance, oxidizing agent. Charcoal: Controls burning rate. For example, gunpowder has more sulfur and less charcoal. Regarding purification: Just heat it. The higher the temperature, the higher the solubility of potassium nitrate. Because there are other impurities in it, you first heat it to boiling, then add water to 30-40, and this is the crystal that comes out.......Okay, now that you’ve learned how to time travel, go and time travel [Gotou]]"

——"Tell me more about the upstairs, I still need these: home-made cement, home-made steelmaking, home-made penicillin, fire hat formula, Galenic sailing ship drawings, steam engine drawings, distribution of various mineral deposits......"

——"Good guy, you really think you are going to time travel!"

The video ends here.

Li Er didn't pay attention to the last rebellious sentence.

Instead, he focused on the first two sentences.

"Did the use of black powder in military affairs begin in the Middle and Late Tang Dynasty?"

"The Tang Dynasty actually started using gunpowder?"

Li Er was surprised.

Originally, he thought that gunpowder came from later generations.

It was still far away from them.

But now......

"Gunpowder actually appeared in the later generations of the Tang Dynasty?"

Changsun Wuji was also shocked by Tianmu's words.

Gunpowder appeared in the middle of the Tang Dynasty.

What does that prove? It proves that there might already be seeds of gunpowder in the early Tang Dynasty!

After all, the emergence of any new invention None of it happens overnight.

It doesn’t just pop out all of a sudden!

"Your Majesty, I suggest that we conduct a nationwide investigation immediately!"

"Especially for Taoist temples and other venues, strict inspections are carried out!"

"At the same time, he ordered to collect clues from all over the country!"

"A department was ordered to be established within the Ministry of Industry to specialize in the development of gunpowder!"

Changsun Wuji and Li Er thought of going together.

Li Er immediately agreed to the request without thinking.

That's it.

A Datang version of the industrial survey.

It was quickly decided.

Of course.

At this time, Datang was still There is no mention of industry at all.

The dimension of the Ming Dynasty.

Compared with Li Er’s surprise. (To read Baoshuang novels, go to Feilu Novel Network!)

Lao Zhu is much more calm.

"It turns out that the gunpowder of Ming Dynasty was called black gunpowder in later generations?"

"Since there is black gunpowder, is there also white gunpowder, red gunpowder, and yellow gunpowder?"

"Is it more powerful?"

Lao Zhu thought with great interest.

At the same time, he looked at the sky and saw the things mentioned in the comment area. He was even more fascinated.

"Home-made cement, home-made steelmaking, home-made penicillin, fire hat formula, Galenic sailing ship drawings, steam engine drawings, distribution of various mineral deposits......"

"The treasures for future generations are truly countless!"

"And these things are called local methods. They must be the same as gunpowder, and they are also what the ancients like us can do."

There are two words clearly hanging in Lao Zhu's eyes - I want it!

And in other planes.

After recording the method of making black gunpowder in the local method,[]

Other emperors.

I also keep an eye on these local things.

Ying Zheng was curious:"Homemade cement? Water is water, mud is mud, what is this cement?"

Liu Che wanted to see the distribution of mineral deposits:"If I could know the distribution of copper mines in my Han Dynasty, wouldn't there be military spending ? ?"

Cao Cao wanted to see steelmaking:"Since local steelmaking can be mentioned by future generations, the steel produced by it must be far harder than ours!"

Liu Bei stared at the three words penicillin:"Military advisor, this penicillin What is it?"

Zhuge Liang shook his head:"Liang doesn't know either."

Zhang Fei shook his head.

"Damn, what's so hard about this?"

"Later generations must have made a mistake and wrote green plum as penicillium. It must be some kind of food!"

Hearing this,

Guan Yu couldn't help but have a black line.

If it is food, will future generations think of taking it to ancient times!!!

The dimension of the Tang Dynasty.

Li Er finished instructing the Tang Dynasty to find out the details. At this moment, he was also focused on the sky. As for those indigenous inventions mentioned

"Treasure!"

"This canopy is truly a treasure!"

"It turns out that there are so many indigenous inventions in later generations that we can use today.......I wish I could take a look at the local method of making steel!"

Compared with other cement penicillins, local steelmaking is the simplest and clearest.

And better quality steel is undoubtedly what Li Er needs most now.

Why?

Better steel means better Weapons!

And the improvement of weapons is the improvement of military strength!

But at this moment,

Li Er was yearning for it.

The moment that all emperors hoped for. A video was refreshed on the sky screen. And the title of the video appeared. It immediately caught their eyes. It lit up. Because the title was: [Travel Book: Several local skills you must master!

】

【The Book of Time Travel: Several local skills you must master! 】

As soon as these words appeared.

All the emperors were shocked immediately!

Not local cement.

Nor is it local steelmaking.

Not the one they wanted to see.

But several kinds!

Ying Zheng was shocked:"Is there local cement? What is this cement?"

Liu Che wailed:"Where is the distribution of mineral resources? Why don't you let me see the mineral distribution!"

Cao Cao and Li Er were all excited:"Steelmaking using local methods!"

Liu Bei also became interested:"What exactly is native penicillin?"

Under the curiosity of the emperors.

In the sky.

The video slowly unfolds

【Time travel is a word mentioned in modern scriptures】

【337 I believe that many people in front of the screen have thought about it more than once, what would happen if one day they encountered such a thing as time travel and returned to Kudat?】

【So, inBefore you encounter time travel, you might as well learn some local crafts】

【It will allow you to live a life as comfortable as a fish in water after traveling through time.】

【Without further ado, let’s get to the point】

【First, the first type: local glass】

【As we all know, glass is a must-have money-making tool for most travelers】

【Jewelry made of glass has existed since ancient times】

【Until the Qing Dynasty, although Western European glass manufacturing technology had been introduced, a piece of high-quality glassware was still a luxury item in society, worth thousands of gold.】

【This was true in the Qing Dynasty, and in other dynasties before glass was introduced, it was even more valuable than gold.】

【In fact, the manufacturing of glass is also very simple.】

【First of all, the raw materials for producing glass are generally quartz (a mineral mainly composed of silicon dioxide, chemical formula SiO2) and soda ash (sodium carbonate, chemical formula Na2CO3)】

【Of course, if you don’t have that condition when you travel, you can simplify it appropriately.】

【First: Crush the sand and soda ash to dry the wet raw materials】

【Second: Melting, the glass batch material is heated to high temperature in a pool kiln or crucible kiln to form liquid glass】

【Third: Then you can tinker with it and sell it to earn some money to upgrade the craft.】

【......】

In the sky.

The first thing that comes up is a word that is unfamiliar to almost everyone.

And Tianmu’s introduction to it is also very bold.

"Glass?"

"Priceless?"

At this time, the true appearance of the glass was not shown on the sky screen.

Instead, some scenes of firing in the workshop were edited.

So Li Er was very puzzled.

"Judging from the introduction of this process, this glass thing is just made of burning paper with sand and other raw materials."

"How can something so cheap deserve to be so valuable?"

"Even comparable to gold?"

Li Erda had some doubts about the authenticity of this statement.

Coincidentally, he was not the only one who doubted it. The people in the streets, villages, and mountains and forests of various dynasties also had some doubts.

"How expensive can something made from a pile of sand be, no matter how expensive it is?"

"That is, if we don’t have gold, how can we not have sand?"

"People in later generations will look down upon us too much. If we bring such a technology from later generations and burn it with a pile of sand, will it drive us crazy?"

"Is it possible that gold can still be burned? Hahaha."

The people pointed and pointed.

Almost no one would think that something made by burning sand would be so precious.

After all, it is just a pile of sand.

What good can be produced by burning it again?

Can it still fascinate us?

Everyone Discussing with gusto.

During the discussion, the introduction to the glass manufacturing process in the canopy ended.

Immediately afterwards, a modern glass handicraft appeared.

Suddenly!

Everyone was dumbfounded!

Transparent!

This is actually transparent!.
