The opening inventory of the top ten young emperors

[Before talking about these three inventions, we need to know a book, which is "Wujing Zongyao" compiled during the reign of Emperor Renzong of Song Dynasty. ]
[In this book "Wu Jing Zong Yao", the proportion of gunpowder and the manufacturing methods of many firearms are clearly recorded. ]

What is the ratio of gunpowder? How to make firearms?
Ying Zheng was looking at the various cannons presented by the craftsmen. It could be said that there were all kinds of shapes and made of all kinds of materials. He had clearly given them the rough sketches that he had decided on!
So when I heard the word "firearms" in the heavenly scroll, I couldn't help but feel itchy.

Obviously, this thing should also be an advanced weapon that appeared because of the emergence of gunpowder. At least for his Qin Dynasty, it is a very advanced weapon.

During these tours, he had become aware of the threat posed by the Huns.
After listening to the story in the Heavenly Scroll and seeing that the dynasties in later times were either troubled by the covetousness of the northern barbarians, or fought endlessly with them, or even destroyed by them, they were even more worried.

In fact, not only in the future, even now, there are foreshadowings of everything that will happen in the future.
Wasn’t the Great Wall of Yan and Zhao built for this purpose?
And now, the hidden dangers of the two countries of Yan and Zhao have naturally become the hidden dangers of his Qin Dynasty. Of course, he must take precautions before it happens.

He had previously thought of connecting the Great Walls built by the former Yan and Zhao countries in the north into one long wall extending all the way to the seaside.
Then he set up beacon towers. If the Xiongnu were to make a move, he would know immediately from thousands of miles away and be able to send more troops to resist in a short time.

Now that he knew about the magical weapon called cannon, he could set up cannons on the wall when the Great Wall was built. Then he could just throw the ignited gunpowder into the Hun army, and he could defeat a hundred of them with one.
He could even use this as an opportunity to penetrate deep into the heartland of the Huns and wipe out all of them, incorporating them into the territory of his Great Qin.

He didn't want to think about it before, nor did he dare to think about it. It was just because the Xiongnu territory was so vast that he might not be able to realize this ambition in his lifetime.
But since he read the Heavenly Scroll, he suddenly felt that this idea was not impossible.

In the Han Dynasty described in that volume, wasn’t there the feat of conquering Mount Langjuxu?
Why can't his Great Qin do that?

In addition to the grasslands, there are also overseas.
It turns out that there are no immortal mountains overseas, but there are countless small countries. I don’t know what these small countries are like now. Even if I don’t conquer them, I’d better go and see them in my lifetime!

"You all need to write it down carefully for me!" As he thought about it, Ying Zheng instructed the clerks around him to quickly record what was said in the heavenly scroll.

The Heavenly Scroll broadened Ying Zheng's thinking, so he was full of imagination about the future of the Qin Dynasty. He did not dare to miss a single word of what was said in the Heavenly Scroll, and every time he asked the calligraphers and painters to stand by his side and let them record the contents of the Heavenly Scroll word for word.

[In addition, this book also records the compass fish, a tool for guiding direction. ]

[Some of you will say that using magnets to guide directions has been around since the Warring States Period. How can it be considered to have been around until the Song Dynasty?]

[What you guys said is correct. Natural magnetic tools for guiding directions have existed since the Warring States Period, such as the Si Nan. And later, more advanced tools were used for military marches, such as the compass car.]

[However, the "Wu Jing Zong Yao" records artificially magnetized magnets. In other words, it was this book that made the artificial magnetization technology widely known. This provided the basic material for the later evolution into a more convenient compass. ]

compass?
This thing sounds very compact and convenient.

But this thing is just to guide the direction. Even if you can make your own magnet, it will be of some benefit to marching and fighting. But why is it included in the four great inventions?
The First Emperor was wondering about this, but then he heard Tianjuan continue:

[The popularity of the compass, and the emergence of the compass based on its manufacturing theory, laid the foundation for the great era of navigation in the future. It allowed humans to identify the direction on the vast ocean and explore new continents one after another.]

[Speaking of this, the up master has to interject. If the compass could be popularized earlier, we Chinese could find our way on the sea earlier. Then high-yield crops such as sweet potatoes, corn, and potatoes could also enter my country earlier. ]

[These are crops that can produce 2,000 kilograms per mu. Even if we only bring back a few seeds and rhizomes from overseas, it can help the Chinese people avoid famine a few times, and save hundreds of millions of people! ]

The crop yield is 2,000 kilograms per mu!
Qin Shi Huang's eyes widened.

How is it possible? How is it possible to have a grain crop that produces 2,000 kilograms per mu?
If there really were such grain crops, then wouldn't his Great Qin and his people never have to go hungry again?
[However, unfortunately, these crops were not brought to the world until the Age of Exploration by explorers after the discovery of America.]
[In China, these crops were not recorded to have been introduced into our country until the middle and late Ming Dynasty.]

[Corn was introduced into the Central Plains and began to be widely planted during the Jiajing period of the Ming Dynasty. Another theory is that it was during the Wanli period. Sweet potatoes were also widely planted in the Central Plains around the Wanli period.]

[In the late Ming Dynasty, there was a man named Qi Biaojia who mentioned the production of sweet potatoes in his book "Yushan Notes: Binpu": "We also got a variety of sweet potatoes from overseas. Each one can be planted on two or three acres of land. Each acre can yield one or two carts of sweet potatoes, which can replace grains and feed a hundred people."]

You can buy a car from just two or three acres of land, which can feed hundreds of people!
All the emperors, especially those before Jiajing, including Emperor Jiajing himself, were shocked by this data.

As an emperor, no matter how absurd his behavior was, he had one common sense, which was "food is the first necessity of the people". As long as the people of any dynasty could have enough to eat, it was a great merit.
That can comfort our ancestors and make us rank among wise rulers.

But if the common people of a certain dynasty couldn't even get enough food to eat, that would be dangerous. The common people would definitely rebel.
Even if this is not the case, the political situation will be unstable, making many people with ulterior motives ready to make moves.

[Potatoes came later, during the Shunzhi period of the Qing Dynasty. Potatoes were not introduced to the Central Plains because of their high yield per mu, but as an ornamental plant. This really makes people feel that it is a waste of natural resources. ]

As the video review reached this point, the screen immediately turned to the vast fields with golden corn and rice ears fluttering. Then there was a shot of a dark-faced old farmer wearing ancient clothes, holding a potato in one hand and a sweet potato in the other, with a bright smile.

God knows how Lei Xiaomeng found this shot, but he did find it, and it was a costume version, so she thought it was a good place to put it. So she edited it in.
However, just as she was looking at the video clip she had worked so hard to find with great satisfaction, she also saw a large barrage of comments appear above the video:
【@Anxious old uncle: Where is this thing? Can I ask Sanbao to find it for me? 】

[@子控凶残老父: Are you sure there is such a thing? The yield per mu is 2,000 kilograms! Where is this magical thing? Where can I find it? ]

[@Pig Man Who Wants to Build a Golden House: Is this thing easy to preserve? Can it be used as military rations? ]

[@心力交昁的代目: Is this thing only available overseas? Is it available in Persia and other places? ]

[V@The Emperor of the Unified World, Long Live the Dragon: If I send someone overseas at this time, can I get this magical object? ]

[@虎头蛇尾李三郎: Our Tang Dynasty is vast, where can we find this thing? ]

[V@鞠躬尽瘁李二郎: Please give me some advice, I will definitely find this item to feed the people! ]

【V@天下只有只有大智慧: I also want this treasure. 】

[V@Super IQ, serious chuunibyou patient: Where is America, can the treasure ship reach it? ]

[@十全老人绘怪: Hahaha, I have all of these. The yield is indeed high, and the sweet potatoes are delicious, especially when roasted over fire, the taste is even more special! ]

……

Under the barrage of comments, Lei Xiaomeng could no longer reply one by one, and could only reply in unison:
[Before this, because the conditions for the great voyages of exploration did not allow it, countries were unable to explore the vast ocean space, and naturally could not discover the new continent of America. ]

[Before the Age of Exploration, only Zheng He's seven voyages to the West during the Yongle period were the most in-depth explorations of the ocean by humans.]

[It is said that Zheng He had reached America on his sixth voyage to the West, but only rumors remain. The information about Zheng He's seventh voyage to the West, and even the information about the construction of the treasure ship he used for sailing, suddenly disappeared inexplicably.]

[Some people say that after Emperor Yongle, the Ming Dynasty once again started a strict maritime ban policy, and the information about the treasure ship was shelved. Later, some people said that it was destroyed in a fire in the palace, and some people said that it was deliberately burned by officials who supported the maritime ban.]

【The treasure ships that Zheng He used to sail to the West were no longer in repair and could no longer go out to sea. Therefore, since the Yongle period, China has never seen large-scale maritime activities. It is both infuriating and a pity.】

[You know, our treasure ships, according to conservative estimates, had a displacement of at least 2,500 tons, hundreds of years ahead of the world. But we just gave away the sea power! ]

As if responding to Lei Xiaomeng's reply, at this moment, the voice in the video also slowly sounded:
[To go a step further, if the Chinese nation had realized the importance of the great voyages earlier and discovered the New World before the Europeans, in addition to land power, we would have noticed the importance of sea power earlier than they did.]

【Perhaps two hundred years ago, we would not have had our country opened to the world by those robbers, and would not have experienced a century of humiliation that almost led to the destruction of our nation and our race.】

The treasure ship was destroyed?
Hand over sea power!
It was only at this time that many emperors noticed that in addition to land power, there was also sea power.

In their opinion, the sea is vast and full of dangers, and what they can get are just some fish, which is not as important as expanding territory on land.

But if what Tianjuan said was true, they were destroying their own martial arts.
This is something that no ambitious emperor would allow.

After seeing Lei Xiaomeng's reply, many emperors forgot to even post comments and fell into deep thought.

When Zhu Houzhao saw Lei Xiaomeng's reply, his expression became more serious, and he ordered: "Go, immediately find the blueprint of the treasure ship for me, immediately!"

He had never thought that sea power was so important, and he did not think that there was anything extraordinary about the eunuch Sanbao's voyage to the West. He just brought some interesting gadgets from foreign countries. Now it has been nearly a hundred years since the eunuch Sanbao sailed to the West. His Ming Dynasty has indeed not sent out a fleet, and can only allow the Japanese to harass the coastal areas, let alone find potatoes, sweet potatoes and corn far overseas.

The earliest corn entered the Ming Dynasty during the reign of Emperor Jiajing. He remembered that Emperor Jiajing was his good cousin!
If that's the case, maybe he can get the other two crops to grow quickly in his Ming Dynasty...

Zhu Houzhao wrote down a few more words on the paper in front of him.
Soon he had a few more questions to ask Tianjuan!
[The book "Wu Jing Zong Yao" includes two parts: military theory and military technology. It is a new type of military book after "The Art of War". It has extremely high academic value.]
[The "Wu Jing Zong Yao" consists of two volumes, each with 20 volumes. The first 20 volumes cover the military system of the Song Dynasty, including the selection of generals and the use of troops, basic military knowledge, military tactics and battle formations, etc.]

[The last twenty volumes also collected many battle examples. The book is rich in illustrations, especially the various bows and crossbows, which are clearly drawn, allowing learners to understand them at a glance. It is a completely systematic military textbook.]

[Later, the authors of this book, Zeng Gongliang and Ding Du, wrote "Seven Martial Arts Books", which became a compulsory course for martial arts.]

In addition to "Wujing Zongyao", Zhu Houzhao also wrote down the name of the book "Wujing Qishu".
Zhu Houzhao thought for a moment and said, "I remember that these two books did not seem to be included in the Yongle Encyclopedia of my great-great-grandfather!"

"I will ask the officials of the Hanlin Academy to check it out. However, the Yongle Encyclopedia contains countless books, so it may not be possible to check it out in a short time." Qian Ning nodded and bowed.

"No need to check, I remember now. When I was still the crown prince, I saw this book in my father's inner study. My father must have read it often. But it is definitely not in the Yongle Encyclopedia."

At this point, Zhu Houzhao couldn't help but complain in his heart: With such an ordinary name, no wonder he had no interest in opening it when he saw it, and it was hard for his father to notice it.
If he had known that the content was so rich, he would have opened it and read it long ago.

"Go, help me get this set of books." After saying that, he thought for a while, "It should be on the second shelf on the right hand side when you enter the door. I can't remember whether it's the third or fourth row, but it's in these two rows. I think I glanced at it two years ago."

[In addition to the two major inventions mentioned above, this book not only lists close combat weapons, but also records the production methods of various weapon mechanisms and various firearms. ]

[Especially firearms like cannons. This book records no less than a dozen types of cannons, and the simplest one even has a hand cannon that can be operated by two people.]

What about the methods of making weapon mechanisms, various firearms, and the dozens of different types of cannons?
Zhu Houzhao felt even more itchy and felt that he had really missed a good book.

But he couldn't be blamed. He remembered that he had only flipped through a few pages of the first volume when he found that it was about the military system of the Song Dynasty. It was also said to be used as a textbook for military commanders and soldiers, so he lost interest.

The Song Dynasty was so weak, what good were their military books? The ancestors who founded the Ming Dynasty, just one of them, could crush a large number of generals in the entire Song Dynasty.

It was for this reason that he was so dismissive of the Song Dynasty's military capabilities that he stopped reading the book. He really didn't know that the following content would be so exciting.

Although he was already used to the emperor's extensive knowledge and strong memory, Qian Ning still couldn't help but marvel at it. He quickly sent the eunuch to get the book, and then he didn't forget to flatter him: "Your Majesty's memory is so good that I'm afraid few people in the world can compare with it."
"Compared to your majesty, I am a fool!"

Zhu Houzhao pretended to kick him and scolded him with a smile: "Stop flattering me. There are many things to do today. Are you ready for the things and people I asked you to prepare?"

"Ouch! All right, I'll go call them in right away."
Qian Ning pretended to cry out in pain twice and hurried to call for help.

Qin Dynasty.
There are actually no less than a dozen types of artillery weapons recorded!
Qin Shi Huang was very jealous. He had tried many times since the last Heavenly Scroll ended, and had just finalized the style of the cannon. He then sent craftsmen to try to make them, but the results were still in different shapes, and he didn't know if they would work well.

But this book actually records more than a dozen forms!
He really wanted this secret book.

[As we all know, the earliest prototype of artillery originated from the stone-throwing machine. This weapon already existed in the Spring and Autumn Period and was mainly used for siege. In the following dynasties, the stone-throwing machine also played a significant role in wars, such as the Thunderbolt Chariot, etc.]

[However, it was not until the Song Dynasty that the stone-throwing machine really evolved into various forms of artillery. This book "Wu Jing Zong Yao" summarized, summarized, and determined the style of artillery, and it became an important long-range weapon for a long time afterwards.]

[This was undoubtedly extremely advanced in the military warfare eight hundred years ago.]

Stone throwing machine!
Ying Zheng suddenly understood!

He immediately looked at the "cannons" in front of him, pointed at the one that looked most like a catapult, and ordered, "Use it and throw the gunpowder bag!"

"Yes!" The soldiers took the order and immediately pushed the "cannon" to the center of the parade ground, and then placed the gunpowder barrels prepared in advance on the stone launcher. They were ready to start firing when His Majesty the First Emperor gave the order.

While looking at this "cannon", Qin Shihuang was still thinking about the corn, potatoes and sweet potatoes that the old lady had mentioned before.
If he can really make the cannon this time, does it mean that he can go out to sea to look for these crops?

The treasure ship mentioned by the master has a displacement of 2,500 tons. Although he doesn't know what this measurement will be in the future, a ship that can sail overseas must be quite large.
Can his Great Qin build such a ship?
[You would have never thought that the Song Dynasty, which had been coveted by northern nomadic tribes since its founding, actually had such a book. ]
[It is such a systematic, comprehensive, advanced, encyclopedic martial arts classic. ]

[However, since the Song Dynasty had such a magical book, why was it finally destroyed by the Jin people? ]

Dear Emperors: That’s right. How were they destroyed?
[In fact, the birth of this book is also derived from the founding characteristics of the Song Dynasty from the beginning, emphasizing culture over military power. ]

Zhao Kuangyin: Isn't it wrong to emphasize civil affairs over military affairs? Now that we have conquered the country, what are we still looking for military generals for? Are we waiting for them to rebel?
Zhao Kuangyi: Of all the things my elder brother did, except for wearing the yellow robe, I think this is the most right thing!

Zhu Yuanzhang: Emphasize culture over military power? Haha... But it would be better for military generals to use their brains less.

Zhu Di: Emphasize culture over military power? Humph, it's almost like giving up your own martial arts! Unless you become a general who conquers the north like me.

Zhu Houzhao: That's right! That's why I almost missed this good book.

[Since Emperor Taizu of Song, Zhao Kuangyin, rose to power through a military coup, he was very wary of military commanders.]

Zhao Kuangyin: ...How can you speak of me like that!

Zhao Kuangyi: Tianjuan really knows everything.

Zhu Yuanzhang: There is some truth in your concerns, but too much is as bad as too little!

Zhu Di: It is most reassuring if you can fight by yourself like me!

Zhu Houzhao: What's wrong with military generals? They are so powerful. I will become a general to protect the country in the future, just like my great-great-great-grandfather, who drove the Mongols out of the grasslands. Now I have to drive the Japanese pirates and Westerners out of the sea!

【After Zhao Kuangyin disarmed his old subordinates, he naturally could not relax the manufacture of weapons and strengthened the centralized management of weapons manufacturing. This is how the Xingguofang in Bianliang and the North and South workshops for weapons manufacturing came into being.】
[It is precisely because of centralized management that there are unified regulations and requirements, and that there is an opportunity to provide data and theoretical support for this martial arts book. ]

[Song Renzong had just ascended the throne. In order to prevent the Song Dynasty from slacking off in military preparation, he called together people and asked them to enrich their knowledge of battle examples and theories based on the achievements of their predecessors. It took them five years to compile this encyclopedia of martial arts.]

【After the book was completed, Emperor Renzong of Song personally reviewed it and wrote a preface for it, which shows his emphasis on the military preparations of the Song Dynasty and his foresight.】

Just then, another barrage appeared.
【@十全老人绘怪: This is natural. Apart from my grandfather, Emperor Taizong of Tang, only Emperor Renzong of Song can be compared with me. 】

This barrage of comments naturally belonged to Emperor Qianlong. He felt very superior after reading the barrage of comments about potatoes, sweet potatoes, and corn. Now that he heard that his idol was recognized by Tianjuan again, of course he had to come out and show his support.

This shows that he is very good at judging people!
[During the reign of Emperor Renzong of Song, the compilation of this book and the military thought it embodied had actually undergone very positive and different changes compared to the reign of Emperor Taizu of Song.]

[Although the policies of Emperor Taizu of Song Dynasty could control the system of military governors that was popular in the Tang Dynasty. For example, during the reign of Emperor Xuanzong of Tang Dynasty, the An-Shi Rebellion caused the Tang Dynasty to decline from prosperity.]

[This method can keep military power firmly in the hands of the emperor himself. It has its positive side.]

Jiedushi?
The emperors of the Tang Dynasty, especially those after Emperor Xuanzong, all had solemn expressions on their faces. Even if they didn't say it out loud, their expressions had already betrayed their thoughts at this time, and they all looked like they agreed deeply.

But when Emperor Xuanzong of Tang heard Tianjuan's words, he was stunned.

What is the Anshi Rebellion and what is the decline from prosperity?
Is this referring to the Tang Dynasty under his rule?
Wasn’t his Tang Dynasty called the Kaiyuan Prosperity by foreign nations, and were they also saying that he was the great Heavenly Khan who was on par with Emperor Taizong?

What is the matter with the Heavenly Scroll?
What nonsense is it talking about!
