"Anyway, don't you mention gunpowder? Gunpowder is the weapon of governance! Whoever dares to disagree, Lao Tzu will beat you to death! ”

"If the anchor carries a depot of explosives at any time, I will see who dares to touch you! Five surnames and seven hopes? But Erl! ”

"I remember that the big guy said what kind of musket before, is the big guy still there? Let's talk about it! ”

"The most traditional gunpowder is made of sulfur, saltpeter, and charcoal mixed in certain proportions, and these three things are not difficult to find. Didn't the Tang Dynasty still use gunpowder to set off fireworks! ”

"Isn't there still a few items that the streamer can carry? If you can't get it together in a short time, I suggest that the anchor still carry gunpowder to cross, maybe he can save his life! ”

After discussing papermaking and movable type printing, the audience moved on to the other two of the four great inventions.

Gunpowder and compass.

"In 1860, Major E. Erz of the Prussian army made guns and shells from nitrocellulose. Commonly known as cotton gunpowder. At this point, nitrocellulose gunpowder replaced black gunpowder as the firing gunpowder, which is commonly known as smokeless gunpowder. ”

"This is only single-base gunpowder, if you add a part of nitroglycerin on the basis of nitrocellulose, it will become double-base gunpowder, which is more powerful."

"Also, on the basis of double-base gunpowder, if the content of nitrocellulose is reduced, and a part of nitroguanidine is added, it will become a three-base gunpowder, a powerful batch!"

"Single-base gunpowder is generally used to fire bullets, and double- and triple-base gunpowder is mainly used to fire artillery shells, and can also be used to make bombs. Although it is far inferior to a mushroom egg, it is enough to crush all the weapons of the Tang Dynasty! ”

"I didn't expect there to be so many big guys in the live broadcast room!"

"It turns out that gunpowder still has a single base, a second base, and a third base! Knowledge! I thought gunpowder was saltpeter and charcoal! ”

"It's all on Baidu, you just don't bother to check."

"Indeed, there are all on Baidu, and the proportions are all written!"

"I still have a regular trick-or-treating (homophonic word) production method here, do you want the anchor to pull a copy?"

"Punishment, the live broadcast room is getting more and more sentenced! I feel like the streamer has to go in before he crosses! ”

"If you really talk like that, it's really possible......"

“……”

If the audience entered the live broadcast room at the beginning, it was just to ridicule Ning Bei's whimsy.

Well, now they've started to get addicted!

In the live broadcast room in Ningbei, you can not only learn history, but also learn technology!

They love it here, everyone here is talented, everyone has technology!

Although these techniques are more or less punishing!

Ahem...... In short, in the live broadcast room of other anchors, you can't learn this!

For the knowledge of gunpowder, Ning Bei also found the relevant content and wrote it down.

In fact, his original intention was to seek wealth, and he simply wanted to be a rich man in the Tang Dynasty.

But after thinking about it, Ning Bei felt that he still had to have the power to protect himself!

Because ancient times were really dangerous, especially for the common people.

Maybe because you look at the officials more, you will be beaten to death by them when you become a gentleman!

Such examples are common!

Take the real offense of the five surnames and seven wangs, if there is no thermal weapon, he alone can protect himself under the threat of these big families?

The answer is clearly no.

Ning Bei didn't know his identity after crossing over, so he rushed to the system, maybe he was crossing into the Tang Dynasty people.

If that's the case, then he'll have to think more about himself.

Hot weapons, put in the Tang Dynasty, are quacking and killing!

If he could bring a Gatling with infinite bullets, he wouldn't have to threaten them without five surnames and seven hopes, he would be able to break them out!

As a generation of civilians and ordinary people who are still workers, Ningbei naturally has no good impression of the ancient gate lord clan!

In his eyes, these people are all living vampires!

Of course, this is only the most extreme idea.

If he wants to do business, he may have to deal with these big clans.

Unless it is a last resort, no one in Ningbei wants to offend.

Doing business is about making money in harmony!

Solving the problem by force has always been the last resort.

Ning Bei then looked at the barrage, and the audience also began to discuss the last invention.

"As for the compass, it's so simple that I don't think there's any need to talk about it."

"Indeed, you only need to take an iron needle and rub it on the magnet a few times, and the iron needle can rotate according to the earth's magnetic field and identify the direction, which children will do."

"Wasn't there Sinan in ancient times? The principle is the same. ”

"Although the principle is similar, the effect is much worse! Sinan can only determine the general direction, which is not accurate. ”

"I think the compass still needs to be improved, and there are no detailed maps and navigation in ancient times, since the anchor has chosen to do business, he must go to various places to buy, and the accuracy of the compass is indispensable!"

"Indeed, in ancient times, if you got lost, you basically wanted to go home for the rest of your life! I remember that there was a scholar who went to Beijing to take the exam, and he didn't find the capital until he died. ”

"Now there is mobile phone navigation, there are satellites, you can go directly to where you want to go, but in ancient times it was not so convenient, and the compass was the best tool to identify the position."

"Brother Bei, you better improve the compass, and you can use it to explain geography to students!"

"It would also be good to be able to build a compass sooner, if we entered the Age of Discovery early! And what's going on in Europe! Let the iron horses of Datang occupy every corner of the world! ”

"If that's the case, then I don't have to learn English anymore!"

“……”

Looking at the barrage, Ning Bei was thoughtful.

Although the method of manufacturing the compass is placed in modern times, it is really simple.

Children can really do it, too.

It's a magnet plus a needle.

But he doesn't underestimate the compass because of this!

On the contrary, Ningbei attaches great importance to this weapon!

In ancient times when there was no positioning, the role of the compass was great!

As small as rushing home, rushing to the capital to take the exam; From marching to war, sailing and exploring continents.

It can be said that life is inseparable from the compass everywhere!

Although these Sinan can also do it, don't forget!

The difference is a thousand miles.

Not to mention anything else, if his business in the Tang Dynasty became bigger, he would definitely have to go to foreign countries to buy goods.

There are a lot of spices in foreign countries, and this is a must-have.

Ningbei doesn't want to eat boiled vegetables every day!

To buy goods abroad, you must cross the sea, then the purpose of the compass is revealed!

It can accurately locate the position of each continent, and in the vast ocean, precise positioning means that the destination can be reached at the fastest speed and the shortest distance.

Instead of aimlessly photographing around the sea, it is a waste of time and may not always find the destination.

Thinking of this, Ning Bei couldn't help but murmur softly: "It looks like the four major inventions have to be improved!" ”

You have to take your time.
