Zhao Kang's private house, the flower hall, the treasure tripod, the cigarette, the carpet, and the singing and dancing. There were a group of Western women inside, with their arms and lower abdomen exposed, and they were dancing barefoot, and all kinds of strange musical instruments filled Jia Cong's ears. He finally saw this relatively open side. On the main seat in the north, Zhao Kang and Gan Xuan were side by side. It is said that the two had already become a match.

After King Yu ascended the throne, Zhao Kang then snatched Liu Zhiyuan from outside with the pen of the ritual supervisor. He was not as easy as him. This eunuch who had not received elite education in the inner court finally succeeded.

When the grapes and wine were poured, Jia Cong and them respect each other from afar. On the west side were Jia Cong and Yu Biao, the left governor of the Jinyiwei, and on the east side were only Shan Ziye, the Minister of Works.

It’s not surprising that Yamakono was not from the Academic Academy of Sciences. He was excluded by Shilin and looked down upon him. He was close to eunuchs, which seemed normal?

In fact, many officials, regardless of whether they have done or not, cherish their reputation at the beginning and want to rely on them in the Qingliu aspect. However, many cultural clubs have very serious opinions, and a considerable number of officials are forced to defect to eunuchs.

"Mr. Shanhai..." Yu Biao changed his mouth. Now many civil and military officials have changed their title to Jia Cong. Zili's name is a title of his peers, and he said that he was respectful.

"I found a piece of news below..." Yu Biao lowered his head carefully and whispered: "The Chief Aunt has always been living in seclusion, and has been living a life of simplicity recently. Zhang Ge has many disciples and is famous. This is a big and small matter in the inner and outer courts, such as imperial tombs, talent shows, enthronements, etc.... Therefore, he became proud in front of others. He once said in public: I am the prime minister... and said: The orphan and widowed mother of the saint must not lose me..."

"He really said that?" Jia Cong sneered strangely. Isn't this another Gao Gong?

Xia Yan, Xu Jie, Gao Gong, Zhang Juzheng, there were also Ming Dynasty in this time and space, but it was not exactly the same...

This high arch of time and space was expelled, which was different from another time and space... In this way, I have a way to get rid of Zhang Fenyi...

"Yes, is this matter big or small? There were also some people present at the Imperial Heaven Superintendent Lu Chunliang..."

Jia Cong narrowed his eyes, nodded slightly, looked up at Zhao Kang, Zhao Kang and Gan Xuan on the main seat, and each smiled, but their smiles meant differently. Zhao Kang knew that Jia Cong had weight in the heart of the new emperor, but he could not find out how big it was. Gan Xuan had a charming smile, and Jia Cong quickly looked at him without squinting.

The Minister of Works, Yamakoto, came to talk to him about firearms and gunpowder. When talking about the formula of gunpowder, Jia Cong escaped Gan Xuan's gaze. Yamakoto said enthusiastically: "The preparation of gunpowder is nothing more than sulfur, saltpeter, and charcoal. The officials were originally craftsmen. Although the imperial court had not opened military weapons bureaus in various places for many years, the officials often collected books from all dynasties to read, and were preparing to decree the imperial court..."

The soldiers in each province have military weapons bureaus, but the firearms they made... I really can't praise them. The most important thing is the military battles in the palace, as well as the Ministry of Works and the Ministry of War.

In feudal society, the firearms of military weapons bureaus in each province must be verified, inspected and reported by the Ministry of War. At least a large number of firearms are needed.

"One king and two ministers...ash, sulfur is the minister, and saltpeter is the king..."

After talking inadvertently, Jia Cong understood that Dashun's gunpowder theory was not beyond the Ming Dynasty's plan, and there were even backwards and regressions.

The ancients' thoughts, including medicine and firearms, all like to use the theory of "monarch and minister, yin and yang, and five elements" and use theory to guide practice.

Is this theory correct?

It cannot be said that it is completely wrong. Traditional Chinese medicine cannot say that it is useless, right? The firearms of the Ming Dynasty were the theoretical guidance, such as "Military Records", "Weapons List", and "War Beizhi". Therefore, the types of firearms of the Ming Dynasty were very considerable.

However, in a nutshell, the gunpowder and firearm theory of the Ming Dynasty were only close to science, and it was only modern science... and many places were mysterious and far-fetched, and even could not compare to Jia Cong's only 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 to one on the left and one to one on the right.

Anyone who has studied high school chemistry can calculate it. Through this chemical equation, the optimal ratio of saltpeter, sulfur and charcoal can be calculated: 74.84%, 11.84%, 13.32%.

The gunpowder formula in the Ming Dynasty was relatively similar, roughly seven to one to one, and the proportions of different types of gunpowder were not exactly the same.

However, ancient people did not really understand the principle of gunpowder, which was first fully understood by the British in the 19th century.

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

Mao Yuanyi’s statement in "Wu Bei Zhi" is quite close, but it is inaccurate and vague. Is it OK to use Yin and Yang and Five Elements to cover it?

At this moment, Jia Cong carefully and patiently explained this process to Shan Ziye. Of course, he definitely couldn't understand the chemical equations. Jia Cong described them in words, concise and straightforward. However, the result was that Shan Ziye's momentum became weak and seemed to have been refuted for many years: "How could Mr. Shan Hai know so detailed? According to Mr. Shan Hai's ratio, I have verified several examples, and it turns out that he is perfect!"

"I just like to study things and learn from them. I like to discuss with Teacher Qin at the beginning, but I have never really tried it. This thing can kill people..." Jia Cong asked again how to make it mines. He had seen it with his own eyes in the West Lake in Yangzhou.

"There are some military weapons bureaus in various places, including the underwater Dragon King cannon, the mixed Jianglong and Jiji Lei. According to the description of the gentleman, Jiangbei Daying used the underwater Dragon King cannon, with cooked iron as a shell and filled with gunpowder. The one who prevents water seepage is a cow squid... I thank you very much. Once the gunpowder formula can be perfect, you will not be afraid of not being able to defeat Westerners..."

In ancient China and the West, the formula ratios of gunpowder in different places were different. At this time, the West could not be so accurate. In addition, the environments in different parts of China are different, and the West is the same. The materials of sulfur, saltpeter and charcoal are different, and it also involves methods to remove impurities to the greatest extent.

In any case, Jia Cong's precise principle analysis is useful. As long as the court supports it, technological development can be improved. In addition, if he is in power, he is ready to vigorously support craftsmen. Isn't Chinese craftsmen good? No, the four major inventions are still from the Chinese, mainly how the authorities do it...

Let’s see what Zuo Zongtang said when he excavated a firearm in Xinjiang? Zuo Zongtang said: I didn’t expect that my great firearm would have such a powerful firearm in China!

When soldiers on the coast of the Qing Dynasty saw cannons, they even splashed them with feces, thinking that they were monsters and monsters, and the cannons in the palace were rusted!

The evil Qing Dynasty is worth merciless!
