Zhao Kang's private house flower hall, Baoding, cigarettes, carpets, a burst of warblers singing and swallow dance, there are a group of women in the Western Regions, their arms and lower abdomen are exposed, jumping barefoot, all kinds of bizarre musical instruments, filling Jia Cong's ears, he finally saw this relatively open side, on the main seat in the north, Zhao Kang and Gan Xuan side by side, it is said that the two have already become a pair of food.

After King Yu ascended the throne, Zhao Kang used the pen of the celebrant to supervise the Jinyi Guard, and Liu Zhiyuan, who was scavenged back outside, was not as good as him, this eunuch who had not received elite education in the inner court, finally came out.

On the grape wine, Jia Cong and they each respect each other, on the west side is Jia Cong and Jinyi Weizuo Governor Yu Biao, and on the east side there is only one person in the Ministry of Industry Shangshu Shanziye.

It's not surprising to say that Shan Ziye was not born in Kejia, and he was excluded and looked down upon by Shilin, and it seems normal to be close to the eunuchs?

In fact, many officials, whether they have done something or not, cherished their reputation and wanted to rely on Qingliu at the beginning, but the views of many literary societies are very serious, and a considerable number of officials are forced to take refuge in eunuchs.

"Mr. Shanhai......" Yu Biao changed his words, and now many civil and military officials have changed their names to Jia Cong, and the word Zili is the title of his peers, and Mr. Shanhai is a sign of respect.

"I found a piece of news ...... below" Yu Biao cautiously lowered his head and whispered: "Lord Shoufu has always lived in a simple place, and he has been able to get by recently. Zhang Ge has many old protégés and great fame, and most of the affairs of the inner court and the outer court are handled by him, such as the imperial tomb, the draft, the canonization and so on...... Therefore, he was proud in front of others, and said in public: I am also a prime minister...... And he said, "Holy fathers and widows, shall not lose my ......."

"That's what he said?" Jia Cong sneered weirdly, isn't this another high arch?

Xia Yan, Xu Jie, Gao Gong, Zhang Juzheng, the Ming Dynasty of this time and space also existed, but they were not exactly the same......

The high arch of this plane is banished, and it is not the same as the other plane...... In this way, I have a way to get rid of Zhang Fenyi......

"Yes, this matter is not big, it is not small, and there were several ...... of Qin Tianjian Lu Chunliang who were present at that time."

Jia Cong narrowed his eyes, nodded slightly, and raised his eyes to look at Zhao Kang on the main seat, Zhao Kang and Gan Xuan, each of them smiled, but the meaning of their smiles was different. Zhao Kang knew that Jia Cong had weight in the new emperor's heart, but he couldn't find out how much weight it was, Gan Xuan was smiling charmingly, and Jia Cong hurriedly didn't squint.

The Ministry of Works, Shangshu Shanziye, happened to come over to talk to him about firearms and gunpowder, and when it came to the formula of gunpowder, Jia Cong escaped Gan Xuan's gaze, and Shanziye said with great interest: "The preparation of gunpowder is nothing more than sulfur, saltpeter, and charcoal, and the lower official was originally a craftsman, although the imperial court has not opened the ordnance bureaus in various places for many years, but the lower officials often collect books from the past dynasties to read, and are preparing for the imperial decree......"

The battalions in each province have armory bureaus, but they have made firearms...... I really don't dare to compliment, and the most important thing is that the military bureau in the palace, as well as the Ministry of Industry and the Ministry of War, have an ordnance bureau.

In feudal society, the firearms of the provincial ordnance bureaus must be verified, inspected, and reported by the military bureau and the military department before they can be used, at least a large number of firearms.

"One monarch and two ministers...... Ash and sulfur are ministers, and saltpeter is the king's ......"

After casually talking about it, Jia Cong figured out that Dashun's gunpowder theory did not exceed the Ming Dynasty, and there were even backwardness and regression.

The ancients' thoughts, including medicine and firearms, liked to use the theories of "monarchs and ministers, yin and yang, and the five elements", and used theories to guide practice.

Is this theory correct?

It can't be said that it is completely wrong, and Chinese medicine cannot be said to be useless, right? The firearms of the Ming Dynasty are this kind of theoretical guidance, such as "Records of Soldiers", "Weapons Spectrum", and "Martial Records", so the types and quantities of firearms in the Ming Dynasty are very considerable.

However, in a word, the theory of gunpowder and firearms in the Ming Dynasty was only close to science, and it was only modern science...... And many places are pretentious and far-fetched, and they are not even as good as Jia Cong's only little modern scientific knowledge......

To put it bluntly, the chemical reaction process of sulfur, saltpeter, and charcoal is as follows: potassium nitrate reacts with carbon and sulfur to produce potassium sulfide, nitrogen, and carbon dioxide.

The ratio is two to three on the left and one to three on the right.

Those who have studied high school chemistry can calculate it, and through this chemical equation, you can calculate the optimal ratio of saltpeter, sulfur, and charcoal: 74.84%, 11.84%, and 13.32%.

The gunpowder formula of the Ming Dynasty was relatively close, roughly seven to one to one, and the ratio of different types of gunpowder was not exactly the same.

But the ancients did not really understand the principle of gunpowder, which was first fully understood by the British in the nineteenth century.

Through the above equations, the principle is introduced: the more carbon dioxide and nitrogen, the greater the heat, the higher the temperature, the greater the lethality. The reverse is true, that is, potassium nitrate must be the most, that is, saltpeter.

Mao Yuanyi's statement in "Wu Bei Zhi" is relatively close, but it is inaccurate and vague.

At the moment, Jia Cong carefully and patiently explained the process to Shan Ziye, of course, the chemical equation, he must not understand, Jia Cong is described in words, concise and straightforward, but the result is that Shan Ziye's momentum has weakened, and it seems that many years of persistence have been refuted: "How could Mr. Shanhai know so much, according to Mr. Ratio, the old man verified a few cases, and it was seamless!" ”

"Where, where, I just like to learn about things, I just like to discuss with Mr. Qin, but I have never really experimented, this thing will blow up people's ......" Jia Cong asked it how to make mines, in Yangzhou Slender West Lake, he has seen it with his own eyes.

"What the Ordnance Bureaus in various places have are the Underwater Dragon King Cannon, the Mixed River Dragon and the Jiji Thunder. According to Mr. Wang's description, the Jiangbei camp used an underwater dragon king cannon, wrought iron as the shell, gunpowder inside, and ox belly to prevent water seepage...... The lower officials are very grateful to my lord, once the gunpowder formula can be refined, he is not afraid that he will not be able to defeat the Westerners......"

In ancient China and ancient West, the formula ratio of gunpowder in various places is not the same, at this time in the West, it is impossible to be so accurate, in addition, the environment in China is different, the West is the same, sulfur, saltpeter, charcoal materials are different, but also involves the maximum removal of impurities method.

In any case, Jia Cong's precise principle analysis is useful, as long as the imperial court supports it, the development of science and technology can come up, in addition, if he is in power, he is ready to vigorously support craftsmen, can't Chinese craftsmen? No, the four major inventions are still Chinese, the main thing is how the authorities do it......

See what Zuo Zongtang said when he unearthed firearms in Xinjiang? Zuo Zongtang said: I can't imagine that I have such a powerful firearm in Shenzhou for a long time!

And the soldiers along the coast of the Qing Dynasty saw the cannons, and they had to splash them with dung, thinking that they were demons and monsters, and the cannons in the palace were rusty!

The evil Qing Dynasty, it is not a pity to die!

War changes history, technology can give birth to another civilization, but it's a pity that they don't understand, and when they do, it's too late.
