It seems to be cost-effective to only allow Deputy Jiang Qianhu to provide saltpeter ore, but Bingjian is only used in summer, which seems not worth it.

Deputy Qianhu Jiang said: "If you need it, I can just sell it to you directly. Saltpeter sounds very expensive, but in fact it is mainly a bit troublesome for transportation and storage. It is not very valuable in itself;

Generally, prices can be increased in summer and the end of the year, one is to make ice and the other is to make fireworks. Except for these two times, the prices are all for transportation;

If that thing is valuable, could the Shaanxi Association be as poor as that?"

Chu Qing understood that Deputy Qianhu Jiang felt that although Chu Qing gave a lot of money, he actually didn't get much money and didn't want to do this.

This is easy to understand.

Saltpeter mines are not valued, because there are too many things, and if there are too many things, they will not be worth it.

Second, this thing is used relatively peacefully and is often used to glaze ceramics and fireworks, which feels less dangerous.

Third, because there are few enemies.

This is interesting, and the concept is a bit big.

War has a huge effect on promoting productivity. There are few hostile countries in Daxuan and there are not many wars in comparison, so the demand for gunpowder is not urgent.

The most important point is that it is difficult for them to solve the problem of the manufactured gunpowder being damp.

The components of saltpeter ore may not be potassium nitrate, but include potassium nitrate and other nitrates such as sodium nitrate.

In the natural environment, the physical and chemical properties of sodium nitrate and potassium nitrate are relatively close. It is difficult to distinguish them in the social environment with low technological level at this time.

Although both sodium nitrate and potassium nitrate are flammable and explosive, salts containing sodium ions have very strong hygroscopic properties and are very easy to absorb water molecules from the air.

Therefore, the gunpowder made is easier to absorb moisture and get damp, so it cannot be used in the military field.

Coupled with transportation, storage and other factors, saltpeter mines are not a shortage of resources.

Thinking about the Qing Dynasty, even every household boiled nitrite soil to supply black gunpowder, Chu Qing felt that the current environment was simply a big advantage for her.

She said to Deputy Qianhu Jiang: "If you find someone to provide me with it, there is no need to do it. You have to give me favors, so I will buy it myself."

Chu Qing pretended that he was not Jiang’s deputy Qianhu, and first refused to introduce the good intention of saltpeter, and then tempted him:

"However, I said that it is not only used for one summer, but also for summer in the north, but not in the south. They can use it for two to three seasons;

Ice made of saltpeter, and saltpeter can be used repeatedly. If you think about it, you have made too many dishes at night, but it’s a pity that you can’t eat them. It’s hot, and it will go bad overnight. Wouldn’t it be better to put them in the ice arc for a night?

?

When we were in the countryside, the leftovers from the village chief’s house had to be hung into the well for storage. We were all envious. Who can afford to drill a well?

But even if it is the village chief, how many dishes can be put in a well?

In the south, even if the scoops thrown away by the wealthy families, they feel that they are wasted, especially when the year is not good, even if it is a wealthy family, they have to save some money, right?

I thought that if you can get saltpeter, I will process the ice cream here and sell it to the south. Wouldn't it be good for us to do this together? I wouldn't have to go to Shaanxihui Mansion from time to time."

After saying this, Deputy Jiang Qianhu felt that this was worth doing, so he hit it off.

With Deputy Qianhu Jiang, who was looking back and working on several saltpeter cooperation projects in the boardrooms of other state prefectures, no one would pay attention to Chu Qing's private work on saltpeter.

As the matter of saltpeter was settled, Chu Qing rushed to Xinlunzhou with great speed.

Before Chu Qing could arrive at the warehouse, Wei Chengyi invited him to the store, saying that there was news from the spies from Voss.

When the door was closed, the only two of them were left in the room. Wei Chengyi brought out a stone as big as a head from the bag for Chu Qing to see.

"What is this?" Chu Qing looked at the stone with his arms, thinking that the stone was very heavy, heavier than an ordinary stone of the same size.

Wei Chengyi didn't say anything, so Chu Qing continued to read. Thinking of the matter of jade mentioned in Xiaobao's letter, Chu Qing was still a little sensitive to stones, and Wei Chengyi brought it up, so he became even more suspicious.

She raised the stone to meet the light and found that the edge of the stone was actually a little translucent. She simply smashed a sharp corner on the ground, and found that it was green!

"Jade?!" Chu Qing asked.

The jade with the size of the head was chiseled with only a thin layer.

Is there something wrong with Xiaobao's jade? Otherwise, why would Wei Chengyi look for him alone?

"Don't be nervous," said Wei Chengyi: "I'm from your side."

"Ah?" Chu Qing was shocked and suspicious.

Her trip to Kyoto has already made her feel in panic. Wei Chengyi is also a veteran of the Secret Investigation Department, so why don’t she think too much?

Wei Chengyi smiled, although there was no difference between his poker face and not smiling: "I said, don't be nervous, this stone was sent by my brother for Xiaobao."

Chu Qing: "Your brother?"

Wei Chengyi's smile magnified a little, making his eyes look softer: "Hou Ze, who has been following my father, I accepted him as his adopted son for my father."

Chu Qing really didn't know about this. Wei Chengyi ran to see his father, and no one told her about what happened next.

Chu Qing stared at her eyes wide and didn't know what to say.

What Xiaobao did there, as long as Xiaobao didn't say it, she wouldn't ask. However, she had seen several people around Xiaobao last time, and Hou Ze gave her a good impression.

But Wei Chengyi belongs to the Secret Investigation Department!

Wei Chengyi: "Are you thinking: Why are Xiaobao and Hou Ze so uncautious? Wei Chengyi is from the Secret Investigation Department?"

Chu Qing blinked several times but couldn't think of how to answer.

Wei Chengyi: "Your son and my father are like one person, and you and I have been through life and death."

Chu Qing: "...That...Xiaobao is young, and there is anything wrong with doing it. Just teach me a lesson as your uncle."

Don’t mention uncle, stay away, be uncle.

Wei Chengyi: "Where is people, they may not be as close as they are blood-related, and they must not be close as they are not."

Wei Chengyi was not very adapted to saying emotional words, so he paused, and he said, "Talk about serious matters, the batch of goods my brother sent is from Meng Chun!"

"What?" Chu Qing was still holding the stone. He was so shocked that he took off his hand and the stone fell down.

Wei Chengyi quickly took it with his eyes and hands, and placed it on the table: "As for that! You sit down and drink a sip of water first, I haven't said anything."

Chu Qing couldn't react while standing, and Wei Chengyi sat down with her shoulder and handed her the teacup: "Drink!"

Chu Qing: "You said."

Wei Chengyi: "You drink first."

Chu Qing had no choice but to take a sip first, feeling a little calmer, and looked at Wei Chengyi.

Wei Chengyi felt that Chu Qing had done a good job in ideological construction, so he said, "They killed Meng Chun."

"What?!" Chu Qing stood up, Wei Chengyi snatched the teacup from her hand, and was about to throw the jade just now, but this time it seemed that the cup could not be kept.

What is the negotiation of the news about the Kingdom of Vos, it turns out to be just an excuse.

"It's so dangerous!" Wei Chengyi said, putting the teacup on the table and shook the tea on his hands: "It's a complete set, don't give it to me!"

Jade is expensive, but this set of tea cups is not cheap either.

The most important thing is that this tea cup belongs to Wei Chengyi.
