After inspecting the newly opened experimental area in the fertilizer workshop, Jiang Xinghuo's heart finally relaxed, and the preparations for praying for rain can be said to have reached the stage of fruitful results and results.

Subsequently, Jiang Xinghuo took Zhang Yuchu and Yuan Hui into the palace together to report the phased results to Emperor Yongle.

"If this thing is sprinkled in the clouds, it will rain?"

Zhu Di looked at the silver iodide powder in the glass bottle that Yuan Hui served, and was a little curious.

"Yes."

Jiang Xinghuo replied: "Clouds are formed by liquefaction of water vapor, the role of this thing is to become the condensation nucleus of raindrops, prompting rain in the clouds, hot air balloons fly to a low altitude of 1,000 zhang to 1,500 zhang, artificially sprinkle these powders into the clouds, the powder spreads at high altitude, it will make the water vapor quickly condense around it, and after reaching a certain volume, it will produce rain, these powders seem to be tiny, but in the cold clouds can produce tens of billions of ice crystals." ”

After listening to Jiang Xinghuo's explanation, Zhu Di looked down for a moment, these powders were bright yellow, Zhu Di shook the bottle and asked, "Is it poisonous?" Can you smell it? ”

"Back to Your Majesty, this thing is not poisonous." Zhang Yuchu hurriedly bowed down and replied.

"Okay, you smell it, third child."

Zhu Di nodded, turned around and handed the bottle to Zhu Gaosui.

Zhu Gaosui was stunned, but he was probably used to it by his father, so he took it and pulled out the cork and sniffed it.

"No, you just sniff it, why are you sticking out your tongue and licking your lips?"

Zhu Di frowned slightly and looked at the third child.

"It smells good." Zhu Gaosui replied honestly.

"!"

Well, according to Zhang Yuchu and Yuan Hui's aesthetic standards for pills, chemical fertilizers can give you a bright pill in the color of Zhu Dan, and it is not surprising that silver iodide powder is added with some licorice-flavored spices.

To be honest, sometimes Jiang Xinghuo feels that they are not alchemy, they are stir-frying, or rather, they are engaging in some kind of art, which must be an art that is both beautiful and flavorful.

Taking back the glass bottle, Zhu Di played with it in his hand for a moment and asked.

"How did two real people refine this thing?"

"Taught by the national teacher."

Zhang Yuchu didn't dare to be greedy, and reported truthfully: "First of all, I found a large amount of seagrass that grew well from Yuan Zhenren's hometown in eastern Zhejiang, burned it into seaweed ashes, and extracted white bitter and salty powder (potassium iodide) from it. ”

"And then?" Zhu Di gradually developed a strong interest in this magical alchemy process.

"Then it was diluted with the green alum (sulfuric acid) that His Majesty saw last time, mixed with saltpeter, and refined saltpeter alum liquid (dilute nitric acid)."

"Next, melt the silver into the Dan liquid, and a new light yellow liquid (silver nitrate) will come out, and mix this new yellow liquid with the white bitter and salty powder extracted from the seaweed ash before, and the final product is this in the hands of Your Majesty."

Zhu Di nodded and said, "Well, it doesn't sound complicated. ”

"The national teacher teaches well, otherwise we can't refine it just by relying on it, I'm afraid it will cost a lot of manpower and material resources."

Zhang Yuchu's touting is too obvious, and Jiang Xinghuo is a little embarrassed, but Zhang Yuchu obviously has his purpose, and he has been looking for him recently, whether there is a new "Dan Fang", even if the effect is not as perverted as chemical fertilizers that can increase soil fertility and silver iodide that can make rain rain in the sky.

If you can buy one, you will sell the Great Shangqing Palace to Zhang Tianshi without frowning.

After all, this kind of thing can be passed down as the treasure of Longhu Mountain.

"Still." Yuan Heng said cautiously, "This thing is good, but the cost of the mess adds up to a lot of money." ”

"Oh."

Zhu Di waved his hand and said: "Use it casually, when I defeat Japan, how much silver will be needed." ”

Zhu Gaochi, the eldest prince with two panda eyes next to him, looked up at his father.

Sure enough, the man was about to become rich, and his waist immediately hardened.

Zhu Gaochi couldn't help but pour cold water on him: "Father, the money for cultivating the Yongle Canon/Ming Encyclopedia has already been spent in the early stage, and the Confucians in Jiangnan have responded to the edict, and Rong Guogong has opened up a new place in the Great Heavenly Realm Temple to specialize in this matter." ”

Speaking of this, Zhu Gaochi couldn't help but count with his fat fingers.

"Last year, Zheng He spent a lot of money donated by the Mid-Autumn Festival dignitaries. Of course, the sale of chemical fertilizer is now also a stable income for the imperial court, which is partially offset, and there is even a surplus, but the year-end reward given to the clan cannot be recovered. ”

"We also have to ask for money to fight Annan, we can't expect to directly 'take' how much property from Annan can come back, according to the national teacher, it is to sell textiles and other goods to Annan to earn back, but textiles have not yet been made large."

If you don't know the price of firewood and rice, Zhu Di quickly stopped the bitterness of the eldest child.

"Where's Necuri? Out of money? ”

"No, you can run mice."

Zhu Di just wanted to say something, but looked at Zhu Gaochi's face, and immediately reacted, how did the money in the inner library not exist.

Of course, it is not greedy for ink, at this time, the emperor's inner treasury and the Tai warehouse of the household department are not very separated, and there are no eunuchs in the inner treasury, and the low-level officials of the household department take turns to supervise, and they change once a year. The money in it was all burned by Jianwen to beat him.

Zhu Di slowly looked at Jiang Xinghuo.

The meaning is also obvious.

- National teacher, make money.

Of course, Jiang Xinghuo can't conjure up money for Emperor Yongle, unless he starts the money printing machine again, but that is undoubtedly digging his own grave.

As for other methods, perfume glass and the like that are common to traversers are also luxury goods sold to the rich, how much money can Daming really make at the moment, there is still a question mark, and it is about the first batch to make more money, and it will return to normal later.

Therefore, if you want to avoid internal friction and really put the economy on another circular path, you still have to build large-scale textile handicraft workshops, use new textile machines to make textiles high-quality and cheap, and then make money from foreign countries through export trade.

After all, the population of neighboring countries in this era is quite large, and the purchasing power is not bad, the Ming Dynasty has a population of 66 million, Japan has a population of more than 10 million, Annam has a population of more than 3 million, North Korea has a population of more than 6 million, plus Champa and the like, just in the traditional tributary trade circle, there is about one-third of the purchasing power of the Ming Dynasty.

Further afield, although there is no exact population data, it seems that there are more people in the entire Pantianzhu region than the Ming Dynasty at this time, although there must be poor Dalit pariahs (untouchables) who cannot afford to wear clothes, but other Shudras and Vaishyas can always afford clothes, and these are all potential customers.

In such a big market as Tianzhu, in Jiang Xinghuo's previous life, Yingge Lan didn't finish eating until the end.

In general, as long as the product is of good quality and low price, the quality of the local cloth is better than that of foreign countries, and the cost is cheaper than the local cloth after deducting the sea transportation fee, then the textile industry really does not have to worry about the market.

"The establishment of a new manufacturing method depends on the Songjiang Prefecture, I wonder what the officials sent out are doing?" Jiang Xinghuo looked at Zhu Gaochi.

"There is a lot of resistance to the establishment of a textile handicraft workshop in Songjiang Prefecture."

As the person directly responsible for the reform of Nanzhili, the eldest prince Zhu Gaochi replied vaguely.

In fact, it is no longer a problem of great resistance, it is simply impossible to carry it out, and the officials of Songjiang are about to write a collective blood letter, but a while ago, the Guozijian made too much trouble, and the limelight of this matter was temporarily suppressed.

If you want to effectively promote the reform, it is inevitable to engage in a large-scale handmade textile industry, which can absorb a large number of employed people and create a lot of income.

But since ancient times, the population has been inseparable from arable land, and even more so in a place like Songjiang Prefecture, where it is impossible to snatch people from the gentry without using any means, expecting them to hand them over and send them to the handicraft area for weaving.

Although Matsue Prefecture is now rich, it has not sprouted to the point where a large number of people have been freed from the farmland and come to work in the city.

Moreover, it is true that Nanzhili is the first experimental field for law change, and Songjiang Mansion is also a selected key pilot area, which is the top priority and the most difficult bone to gnaw.

Jiang Xinghuo was silent for a moment, everything was difficult at the beginning, for these, he had already expected it.

Therefore, now things have become a link and a link, if you want to change the law, if you want to ignite a large-scale handmade textile industry, you have to settle the public opinion at the center first, and you can't let Jingqing's blood oath come true, if God doesn't rain, then help it rain artificially.

Fortunately, the two necessary conditions for artificial rainfall, hot air balloon and silver iodide, the latter has been solved, the former should not be too much of a problem, when the time comes, take a saturation lift-off, each hot air balloon carries a bottle of silver iodide powder, a few more hot air balloons at a time, a high probability is possible.

"So I asked the national teacher one last time, can artificial rain be successful?"

"It will definitely work out." Jiang Xinghuo cut the railway.

At this time, there must not be any hint of retreat, and Emperor Yongle must not feel that he is not confident enough.

Zhu Di got the letter from Jiang Xinghuo, and after confirming that if it really didn't rain, he could artificially rain, and asked Zhu Gaosui: "Third brother, how is public opinion?" ”

Zhu Gaosui replied: "In terms of public opinion, with the preliminary work of Rong Guogong presiding over the Yongle ceremony, those Confucians are no longer making trouble, the script of "Journey to the West" compiled by the national teacher, Sun Wukong and Che Chi Guoshi fighting and praying for rain, are now widely circulated among the people, and then the Shilin side dominated by Guozijian, the methodology of Gewu proposed by the national teacher in Taiping Street has also caused a lot of controversy. ”

"In short, public opinion has now been fully mobilized, and it can be said that everything is ready, just waiting for the rain."

Zhu Di sighed: "Artificial rain is always risky, if only God could rain on his own." ”

"It's not necessarily a good thing, you have to be careful of flooding."

Jiang Xinghuo reminded: "After years of war, the Yellow River, the Huai River, the Yangtze River, the Wusong River, and the water conservancy projects have not been taken care of for several years. ”

Hearing this, not only Zhu Di, but even Zhu Gaochi frowned, bad things, one after another, seemed to have a chain reaction with an omen.
