As soon as the words were spoken, Chen Kai was immediately stunned on the spot. Many eggs and radishes were placed in the gunpowder manufacturing workshop. Not only did he know the reason, but he also asked the craftsmen to do this.

.

The composition ratio of black gunpowder in the Ming Dynasty is described differently in various books, but among them, the ratio described in the "New Book of Jixiao" written by Qi Jiguang is actually no different from modern black gunpowder. Zheng Chenggong went to war

During this period, Chen Kai was reading Qi Jiguang's works when he had nothing to do. There were so many shocking things in them that he could read. If Qi Jiguang's book was only used as a textbook explaining the mandarin duck formation, it would be a waste of resources.

Qi Jiguang solved the problem of the proportion of gunpowder for Chen Kai. The rest, in order to further improve its actual power, Chen Kai considered two points, one is granulation, and the other is to improve the purity of the raw materials. But these two

Unfortunately, with the level of science and technology in the late Ming Dynasty, there was no need for him to take action personally.

The existence of granulated gunpowder in the Ming Dynasty is supported by unearthed cultural relics, but many Ming Dynasty civil servants and generals with two swords did not understand it at all. But this problem did not exist in the Ordnance Bureau, at least Zheng Chenggong brought it from Quanzhou

It seems that the gunpowder craftsmen who returned are not that amateur yet.

As for improving the purity of raw materials, such as charcoal, sulfur, and saltpeter, people in the Ming Dynasty had relevant technologies. Even though they seemed unreliable, the actual results were very good. Even in the late Qing Dynasty, the products purified in eastern Guangdong

The power of gunpowder was actually comparable to that of Western black gunpowder at the same time, so much so that even the Manchu and Qing courts were so surprised that they could not help themselves. At that time, the technology used was still the purification technology used in the Ming Dynasty!

In Chen Kai's Ordnance Bureau, sulfur is imported, so there is no need to purify it. In addition, charcoal is relatively simple, only saltpeter. Since it has been self-produced, the purification process must be kept up, and the used

The process requires radish and egg white for filtering.

I remember when the craftsmen first purified the nitrate from the manure piles, Chen Kai watched them add radish and egg whites to it as if they were boiling soup, and then continuously sifted out impurities, and sweat began to pour out.

Chen Kai felt it was necessary to study the chemical formulas and how eggs and radishes adsorb and transform impurities. He just didn’t have the time, but the actual results he obtained were very good. The original soil salt can be purified into white crystal form

, and Chen Kai had to marvel at the wisdom of Chinese working people.

Of course, the more important question is that Chen Kai finally figured out why the two guys looked at him so strangely this morning!

"Damn it, I'm a big eater, I'm a big eater, I'm a big eater, say important things three times."

The reason for the increase in the price of eggs and radishes in Nan'ao Island is that Chen Kai's technology of accumulating manure and nitrate has begun to be practical and mass-produced. However, the nitrate produced cannot be directly used in the manufacture of gunpowder and needs to be purified.

Purification requires a lot of radishes and eggs.

These ingredients are classified as raw materials in the account books, and they go through the accounts of the gunpowder manufacturing workshop alone. The people in the Ordnance Bureau are not very clear about this matter, and there is no record in the account books there. In addition, Chen Kai’s Chaozhou

Okay, on the contrary, he, the general manager, almost directed and acted in a black humorous absurd drama.

"You continue to work and don't need to worry about me."

Wiping his sweat, Chen Kai walked into the office room of the workshop. There was an accountant here specifically. Chen Kai reviewed the account books. This batch of ingredients was indeed recorded, and the quantity was indeed large enough to affect South Australia.

The level of commodity prices on the island.

It was embarrassing, but the problem was found, which made Chen Kai breathe a sigh of relief. Unfortunately, just as he was relieved, he unexpectedly heard the cook talking to him as soon as he returned to the small courtyard of the main town house.

Her man muttered, saying that she heard about the increase in food prices when she was collecting vegetables from the kitchen of the main town hall. She even worried that the rising food prices would not affect those of them who were eating public food.

People feel happy.

"Yesterday it was eggs and radishes, today it's grain. I shouldn't have eaten this."

………………

The Ordnance Bureau's inspection officially ended on the second day of Buda. The workshops and gunpowder casting workshops in the city, the saltpeter factory, charcoal burning factory and weapons testing ground outside the city were all able to operate normally according to his regulations, which indeed allowed

Chen Kai felt relieved.

In the next few days, Chen Kai focused on inspecting the other three towns on Nan'ao Island except Shen'ao Town, where Nan'ao City is located, to explore the specific situation so as to facilitate governance. This work did not last long, because Nan'ao Island was so

Da, he had no intention of going down to various villages. However, with Zhu Yao's arrival, the visit to Long'ao Town had to end early.

"I have an unkind request. I would like to ask Chen Canjun to tell us how you led Master Wang to outwit Chaozhou City and kill Che Renzhong?"

He was not here for a martial arts competition. Chen Kai was very lucky and happy. Especially this sentence of outsmarting always made him feel like a feather fan. The explanation was just a light talk, and Chen Kai didn't think he had done anything remarkable.

If he had entered Liaoyang City during the Tianqi Dynasty and killed Nurhaci, he might have boasted about it once or twice. It was really not a big deal for a small car to carry a heavy responsibility.

However, such things are not that simple in the eyes of others. At least Zhu Yao admires Chen Kai's courage, especially when he sees that Chen Kai has no martial arts at all.

Regarding this matter, Chen Kai simply proposed a visit to Haishan Island. Zhu Yao welcomed this very much and even seemed proud that Chen Kai could visit his hometown. But unfortunately, he was doing this

There was no need for a tour guide, because he had met Chen Bao and was about to leave for Chaozhou to meet Zheng Chenggong and complete his official surrender to Zheng Chenggong's command.

"This man is quite kind."

"Well, this person is indeed much more trustworthy than Huang Hairu, Xu Long and the like."

The next day, Zhu Yao set out for Chaozhou, while Chen Kai took the guides, several officials, and guards left by Zhu Yao and boarded Haishan Island. This place is only four nautical miles away from Nan'ao, and it took half a day to get here.

It's no use for an hour.

On Haishan Island, there are some scenic spots such as the Tomb of the Song Dynasty Prime Minister and the Longfu Ancient Temple. Chen Kai really does not have the time or inclination to visit them. The main task of his trip is to conduct a preliminary survey of the topography and landforms of Haishan Island and the production of local people.

During his life, he stopped by to take a look at the tiger-kicking stone at Liyu Village in Elephant Trunk Mountain. When he went to Zhu Yao's hometown, he stopped by and took a look. However, it also aroused confusion among the attachés and local people because of this tiger-kicking stone.

Although the historical events behind it are related to Zhu Yao, they are far from happening, and it is difficult for him to predict whether they will even happen.

After leaving Haishan Island, Chen Kai did not return directly. Instead, he rushed to Dongshan Island and walked around before returning to Nan'ao Island. The overall situation in these two places left Chen Kai speechless. At least there was a salt field in the latter.

Intensify development efforts, but the former seems to have nothing worth mentioning except for fishery. Even the Sanbaimen Port that he has longed for for a long time did not give him too many illusions about the bustling ships.

Fortunately, the islanders of Haishan Island have no resistance to joining Zheng Chenggong's command. However, if they want to use something like people's support, it is a bit exaggerated. They are nothing more than Zheng Chenggong's command.

With the momentum of sweeping the tide, I chose a way to continue to maintain a normal livelihood, that's all.

This is not because they ignored their old masters of their homeland. The Ming court imposed exorbitant taxes and miscellaneous taxes everywhere. Like many Chaozhou local tycoons, they had already formed a stronghold to resist taxes when the Ming court ruled this land. What changed was only the government, not them.

. Just like the famous saying in Su Qier: "If you are really wise and powerful and make the country peaceful and the people peaceful, who would be willing to be a beggar?"

The Chinese people are good at governance. Unless they can't survive, few of them are willing to fight against the government. Since they have already chosen this path, Chen Kai is not so optimistic that Zheng Chenggong can easily conquer Chaozhou if he takes it.

The people of Chaozhou. After all, this is not a real-time strategy game!

In charge of the civil affairs of Nan'ao and Dongshan Islands, Haishan Island will probably soon be added to the post. Chen Kai is not in a hurry. Deepening the roots is the key. When he returns to Nan'ao Island, he will return to the main town as soon as possible.

He went to the small courtyard of the government to formulate relevant development plans based on the actual conditions of these three places, especially for the Arms Bureau. However, as soon as he stepped over the threshold of the small courtyard, Chen Kai heard a soft female voice speaking out.

His call.
