History live broadcast: My audience is the ancestors

Chapter 108 Four Great Inventions ()

汉朝
Liu Che also asked Sang Hongyang to copy it. After all, even the big men lacked these things. Although Cai Lun was said to be from the Han Dynasty, he didn't even know what Lao Shizi was from the Eastern Han Dynasty?

Who can tell him why his Han Dynasty cracked?
Was Wang Mang really summoned just because of his great-grandfather's lie? Speechless.

Liu Che was speechless.

Su Yue looked at the comment area and said, "Okay, now let's take a look at the last four great inventions, which is gunpowder!"

As soon as they heard this, the ancestors before the Song Dynasty were excited. This is gunpowder!

When I talked about Zhu Di and Zhu Zhanji before, there were some videos where you can see their lethality. Although they may not be that powerful, they will definitely get better and better over time!
They are ready to carve knives! Please tell me later!

Su Yue did not let them wait too long and said: "Okay, now let's see how it is made. But this, we can't go too far, we can just mention it a little! Otherwise my live broadcast room It’s gone.”

My charming and short-lived ancestor: Agreed! And the inspections have been strict recently, so we must pay attention to it.

Fuling: Agree! I am always here! Please pay attention.

I send my love and the bright moon: I am just a chestnut!
Wan Ning can't sleep: Yes, our management will be on guard 24 hours a day, so be careful.

Qin Dynasty
Ying Zheng looked at Li Si with some confusion and said, "Who is that administrator?"

Li Si was still frantically carving words. When he heard this, he was obviously stunned for a moment, and then he came to his senses and said: "Administrator? He should be the person who manages the speech of these people. Wei Chen remembers that someone was kicked. He probably just couldn't see it. This anchor’s live broadcast room.”

Ying Zheng nodded, agreeing with Li Si's statement.

Tianmu was peeking at the screen secretly, but when he heard this, he realized that he did not display the administrator's tag, and corrected it immediately!
The sky flickered slightly, and several people had suffixes after their names.

Fuling (Guan): We won’t kick people for no reason, don’t worry!
I can’t sleep at night (Guan): Agreed! Although we have been watching the live broadcast, we will not play casually.

My charming and short-lived ancestor: Well, now let’s get to the next invention!

Yun Xi: Yes! Let’s change the subject! If we continue chatting, super management will come.

Don’t let the world grow old: I agree! Yueyue, your time is up, hurry up and play!

Yingxing of the Ming and Song Dynasties, "Tiangong Kaiwu·Gunpowder": "All gunpowder is mainly saltpeter and sulfur, supplemented by plant ash.

The nature of nitrate is extremely yin, and the nature of sulfur is extremely yang. The two divine objects of yin and yang meet in a seamless space, and when they come out, the characters are stunned, their souls are scattered, and their souls are shattered. "

Su Yue looked at a bunch of professional nouns and said, "Let's just say, I don't know how these proper nouns are made. I remember there is a formula, which is monosulfide, dinitrate, three charcoal, add some sugar, Da Yiwan."

My charming but short-lived ancestor: I don’t understand why sugar is added to gunpowder?

I send my love and the bright moon:? ? ? Sugar is a strategic resource. Adding sugar to gunpowder will make it more powerful.

Fuling (Guan): Yes, I remember that we still have to limit the amount of sugar we sell here.

Not allowed to see white hair in the world:? ? ? So outrageous? Zundu and fake toot?

Fuling (Guan): Zundu, I also thought it was outrageous at the time.

My charming and short-lived ancestor: It’s the same with us, but most families don’t use so much, so they don’t know.

Yun Xi: That’s right, so most people won’t know or care.

Su Yue looked at the PPT and sighed: "That is to say, if I can, I would like to send two copies of "Tiangong Kaiwu" to Zheng'er and Cheer! I can't even imagine how much this book will change the Qin and Han Dynasties!"

My charming and short-lived ancestor: Yes! I want to give it to them too! It would be better if it comes with a world map.

Fuling (Guan): Agreed!

I send my longing to the bright moon: I want it too! It's a pity that I can only think about it.

Tianmu looked at the situation in the comment area, then looked at his own little treasury, and suddenly felt that it was not impossible to give them some money.

Tianmu quietly bought a few books and maps, and then sneaked over to Ying Zheng. Looking at the busy group of people, Tianmu put the things in Li Si's hands.

There is no way, Brother Zheng keeps looking at the sky and doesn't pay attention to him!

Li Si was shocked when he saw the book that suddenly appeared, but when he saw the name, he became happy inside!

It was clearly the Qin seal version of "Tiangong Kaiwu". Li Si immediately reported it to Ying Zheng. Ying Zheng looked at the content and was overjoyed. He immediately handed it to Li Si and said, "I leave it to you. Be sure to do it well." .”

Li Si immediately agreed. He knew the importance of this, and it seemed that his workload was about to increase again.
