Feng Yong would definitely not admit to picking up the feathers of feudalism in the Han Dynasty.

But the crux of the problem is that if the Prime Minister of the Han Dynasty wants to suspect a country bumpkin, does he need evidence? Does he need the country bumpkin's admission?

Feng Yong looked outside. Autumn has begun, and it is the time when autumn tigers are rampant. The sun is shining, and there is no sign of frost, let alone snow.

He had no choice but to sigh and promised the Prime Minister to give the chicken feathers he collected to the Prime Minister's wife free of charge.

Of course, he would never give away the duck feathers.

"One more thing, Mr. Xi said that you promised her that you would compensate her for a season of autumn silkworms. It's already autumn. Where are your silkworms?"

"Oh, I forgot about this. But before I came out, I had already taught the method to my disciples. Please ask Madam to go to Zhuangzi to get it."

Feng Yong scratched his head and thought, what's the big deal, just a little silkworm seed? I'll give it to you.

At the same time, I despise a certain prime minister in my heart. After all, you are also a powerful prime minister. Thousands of miles away, you still want to secretly collect debts for your wife? Raise your ears!

Zhuge Liang naturally didn't know what Feng Tubiao was thinking.

Although he had been mentally prepared, he couldn't help but raise his eyebrows when he saw Feng Yong so casually saying that he asked his master to go directly to Zhuangzi to get silkworm seeds.

"Do you really think you can hatch silkworms in autumn?"

"It's a simple thing."

If you want to coax silkworms out of their eggs in autumn, you have to put the silkworm eggs in a low temperature environment for a few days.

Refrigeration requires the use of nitrate.

The aged stove soil in the kitchen, as well as the surrounding soil that has been composted for at least one or two years, or the soil scraped from the walls of the compost pile, are most convenient for making saltpeter.

The method of making local saltpeter in rural areas is very simple.

There is often a layer of fluffy white mold at the base of the hut walls in rural areas, which is naturally precipitated nitric acid.

When I was a kid, I would often scrape it off, mix it with finely ground charcoal, and store it carefully.

During the holidays, I would pick up the dead firecrackers, pour out the gunpowder inside, and mix them with the homemade powder. It would be a lot of fun to play with.

Of course, there are also greedy people who mix too little gunpowder and add too much powder, resulting in a fire that cannot be ignited. That is to say, they feel like crying without tears.

In fact, it is the principle of black powder.

Although time travel does not involve gunpowder, it is just a fake rabbit.

But there are not enough materials, and there is no old man with a white beard with him, and there is no system that can be upgraded with a "ding" and then opens up permissions for you to buy and buy. What can you use to make gunpowder?

Only charcoal is not a problem.

As for nitrate, it used to be a problem.

That is to say, only when you have a little power and some manpower can you get a real solution.

Even if the soil saltpeter produced by the aquaculture industry is not enough, there are actually a large number of saltpeter caves in the mountains of Hanzhong, Sichuan, and Yunnan.

With the power and manpower at hand, as long as he is willing to send a large number of people to look for it and spend some time, he should be able to find it.

At most, we can put more effort into it and have someone dig out the saltpeter inside and refine it.

But where to find large amounts of sulfur?

Feng Yong couldn't think of any sulfur mines in the territory of the Han Dynasty today - I remember that the geography books of later generations only said that there were sulfur mines in Daxijiang.

As for the industrial extraction method... Feng Yong could only lament once again that he was not a chemistry major.

And I heard that most industrial chemicals containing sulfur are toxic.

When this kind of thing starts, you definitely have to get started by yourself, and no one else can help at all.

It’s hard to believe that even if I haven’t gotten rid of it after a year or two, my body will develop various abnormalities due to inhaling too much sulfide.

For example, if your hair falls out, your teeth become loose, etc., if you get lung cancer or liver cancer again, you will definitely be the second time traveler to commit suicide because your knowledge is too advanced.

The first one is Senior Wang.

Besides, even if the materials are complete, the black powder produced is not very powerful - the explosive power of commonly used explosives in later generations is more than ten times that of black powder.

Otherwise, would Nobel be too full to develop powerful explosives?

The ordinary explosive bags that are activated by detonators in later film and television works contain yellow explosives, also called TNT, which are not the same thing as black powder.

If you want black powder to have the same power as an ordinary explosive bag, you will probably need a truckload of it, and it will have to be packed tightly.

Small packets of black powder are used to explode beautifully and scare people - or they can be used to make thunder and perform miracles.

If black gunpowder wants to produce a certain effect, it can only accumulate power in quantity.

The manpower, material resources, and materials used in this process have increased exponentially. For a big man like this, if he saves up the entire country for a few years, he will basically use it all once to blow up a big city.

And it may not be effective, because you have to bury tons of black powder under people's city walls.

As for making high-power explosives, let alone that.

First of all, Feng Yongyong was born in chemical engineering and did not have that much knowledge.

Secondly, he doesn't think he has the aura of immunity from death like Nobel - when he was experimenting with nitroglycerin explosives, Nobel's brother was killed and several assistants were also killed, but he was the only one who survived.

.

Even in the various explosions that followed, Nobel escaped death every time.

If this isn't a death-free halo, what is it?

In layman's terms, this kind of person has a tough life.

The kind of person who stands under a tree together, and when God thunders, others are struck to death but he remains unscathed.

Therefore, Feng Yong's attitude towards black powder is: just do it if you have the materials, save as much as you can, but don't force it.

"How many silkworms can be hatched?"

Zhuge Liang asked again with concern in his eyes.

Feng Yong glanced at Zhuge Liang and knew what he was thinking.

"As long as silkworm eggs can be hatched, they may not be hatched. This method is currently not popular among the people. At most, it can be used by wealthy families."

Just for several days of continuous cooling, the amount of saltpeter used is not a small amount. This is not just scraping some dirt from the corner of the latrine.

How many people know the process of refining nitrate?

The process of refrigerating silkworm eggs to survive the winter is unique to Feng Yong's family.

Besides, there are no thermometers these days, so cooling depends entirely on feeling.

In later generations, there will be specialized refrigeration equipment such as refrigerators. There is a certain failure rate in doing this! What's more, Feng Yong's extensive approach.

Therefore, the failure rate of hatching silkworms in autumn is unprecedentedly high.

However, as long as you are willing, you can find ways to make the silkworm moths lay more eggs in spring, so you don't have to worry about not having enough silkworm eggs.

But for ordinary people, if this method fails, all the manpower, material resources, money and food spent from making saltpetre to hatching silkworms will be wasted.

How can the people in Guizhou, who have just had enough to eat, afford it?

When Feng Yonggang returned to Jincheng from Hanzhong and promised Huang Yueying to compensate her for a season of autumn silkworms, he had people under him who wanted money and silkworm eggs.

Moreover, in terms of using nitrate, those who followed Feng Yong in farming also piled up fertilizer for more than a year. At the same time, Feng Yong also asked Zhao Guang and others to find ways to help.

Just like that, he worked on it for a long time and recorded a bunch of test conditions before he could barely measure it.

Since the people cannot do this for the time being, it is not considered a major national event, and it can be used to hide personal interests and make money.

Therefore, Feng Yong has no plans to publish this method for the time being.

It is better to cheapen those big families than to cheapen the internal brothers of the Xinghan Society.

When the time comes, we will centrally supply silkworm seeds at one price internally and one externally.

Love or not!

Anyway, the lack of luxury goods like silk and brocade will not have much impact on people's lives, so what are you afraid of?

As for earning foreign exchange from Shu brocade foreign trade - I have contributed so many things, which one is not related to people's livelihood?

Who doesn’t know that the imperial court now has money and food in its hands? Why does it still need to keep an eye on the income from Shu brocade all day long?

And it doesn't mean that the court's income in this area has been reduced, it just hasn't allowed you to increase it.

You can’t always point at me when plucking wool!

It's not easy for me to make some money.

Zhuge Liang obviously understood the meaning of Feng Yong's words.

Although I had heard this statement from my husband a long time ago, when I heard Feng Yong confirm it again, I was a little disappointed at the moment, but I didn't say anything else.

After coming out of Zhuge Liang's place, Feng Yong saw that it was still early, so he went to the place where he used to live in the city and took a look at Eshun.

Eshun's vitality is pretty good. In just a few days, he can throw away his crutches and try to walk two steps on his own.

It seems that his recovery time is faster than estimated and will not delay the plan to pacify Yuejun.

Feng Yong nodded with satisfaction and said to Eshun, "I have good news to tell you. I went to inquire about it. After Gao Ding's wife and children were captured, they were kept in the army by the Prime Minister and were not harmed. You can see them in a few days."
