Xihuan took a look at the situation, and saw that there were no ups and downs in the face of Baili Yan, and then walked straight to the right seat. After sitting down, Xihuan continued:

"Yongxinghou, please take a seat."

"Her Royal Highness the Crown Princess Xie."

"Marquis Yongxing didn't go to the court early this morning, and I don't know what to do when I come to the house."

"It's not a secret, today's shortage of gold and silver is getting worse and worse, so Ben Hou offers a good plan to the king to break this situation."

"Oh, the Marquis of Yongxing has a good policy, shouldn't he discuss it with the Manchu Dynasty civil and military and the crown prince, why do you want to mention the matter of establishing the country and the state with my female liu." Xihuan asked rhetorically, pretending to be indifferent, and it was faintly visible in his eyes that he was staggered with Ji Jinsheng's gaze, which was very secretive.

Bai Liyan ignored it at all and continued to describe his words:

"This law is related to the transactions between countries and our Xianguo, and the Jin State is the upper state of our Xianguo, the king thinks that he must not owe the interests of the Jin State, so he ordered Benhou to come to discuss with the crown princess, hoping that the two countries can advance and retreat together."

Bailiyan opened her mouth to say the word "indebted", what she said was so high-sounding, Xihuan was quite unhappy to listen to. Even though she was extremely unhappy in her heart, but at the thought of losing tens of thousands of gold and silver anytime and anywhere, Xihuan still endured it, and continued to maintain her noble and graceful, seemingly harmless smile, she said:

"Since it is related to the royal brother of the palace, the Marquis of Yongxing may wish to come to the palace to listen to it, if it is a listen, I think my royal brother is also a reasonable person, and he will not be inflexible."

"With Her Royal Highness the Crown Princess, Ben Hou is here today to talk openly and honestly with the Crown Princess."

Bai Liyan took a sip of the teacup, and then explained in detail the stakes of the matter of "leaving enough to give up the shortage".

Of course, Xihuan doesn't understand the economic position, Ji Jinsheng has been cultivating Xianguo for nearly 20 years, and the doorway here is the thickness of a layer of paper, and he naturally figured out everything if he pierced it.

"Your Royal Highness the Crown Princess, if the two countries can advance and retreat together and implement the method of leaving enough to give up the shortage, the situation will be reversed, which will be extremely beneficial to both Jinxian and Shanxi."

"Well...... A female streamer in this palace, where do you understand these truths. But since the Marquis of Yongxing said that it was profitable, the palace thought that the Marquis of Yongxing would not bully me, a woman. However, this matter is very important, and the palace has to discuss it with Yin Yangjun in the long run, and the Marquis of Yongxing will not mind. ”

"Don't dare. This matter involves many yamen, and it cannot be done in a day, and it is not very important to delay it for some time. Ben Hou still has chores with him, so he will leave if it is inconvenient, so he will leave. ”

Bailiyan got up and saluted and wanted to leave, but Xihuan shouted to him:

"Yongxing Hou is slow."

"What advice does Her Royal Highness the Crown Princess have?"

"In recent years, all kinds of schools in the city of Chenling have been taught the method of arithmetic, and the general feeling of this palace Tuo'er and Ping'er is not very useful, and this palace wants to ask, I don't know what is the use of Yongxing Hou Guang's method of arithmetic?"

Bai Liyan was a little stunned when she heard the news, and she didn't think that Xihuan would ask about such trivial matters. After a moment's thought, he said:

"It is not only the method of counting, but of course it is the calculation of all the laws in the world, from the expenses of financial accounts to the cycle of the sun, moon and stars, all of which can be clarified by the method of counting. Since the two sons learned this method in the school, it is always beneficial to learn more, I don't know if Her Royal Highness the Crown Princess is satisfied with the answer of this marquis. ”

"Oh...... Yongxing Hou is bright and fair, this palace will not doubt what Yongxing Hou said, Yongxing Hou please. ”

"That Ben Hou has taken his leave."

Soon after the school was set up in the city of Chenling, Xihuan did not think so, and then the sons of King Xian and the daughters of Bailiyan entered the aristocratic school, which caused Xihuan to be vigilant, so he let Jiang Tuo and Jiang Ping enter the aristocratic school to study.

Children, teenagers, middle school to literacy and hyphenation and basic secondary mathematics education, supplemented by simple and easy-to-understand natural science, to say how much gold, in terms of technical content, in fact, there is not much, the only can be learned and used only basic mathematics, but only stay in life mathematics, does not involve advanced content.

For this reason, Xihuan specially sent the news to the Jin State, hoping to find the true meaning of the Xianguo to enrich the people and strengthen the army.

However, in the past few years, not only has we not found the way to enrich the country and strengthen the army, but the Xianguo mathematics, which has been symbolized, standardized and standardized, has formed a natural gap with the huge thinking gap between traditional Chinese mathematics, and without the guidance of insiders and systematic popularization, it is difficult to transform it, let alone apply mathematics to other fields.

When Baili Yan left, Xihuan asked Ji Jinsheng:

"General Ji, what Bai Liyan said just now is true or false?"

"Your Highness is asking about the shortage of two catties, or the matter of counting."

"Naturally, it's a matter of missing two pounds." Xihuan emphasized.

"My subordinates thought that the method of 'leaving enough to give up what was lacking' was very profitable. Moreover, the news should be transmitted back to China as soon as possible, and the full amount of gold and silver should be deducted, and at the same time the price of commercial goods should be raised by 10% to 10% and 1/2. ”

"Jin and Xian are advancing and retreating together, how will the other countries react, if they take the opportunity to provoke, with the temperament of Brother Wang, they will never send a single soldier for the interests of Xian. But if you don't help Xianguo, if the shortage of two catties intensifies, if it becomes a foregone conclusion, Xianguo is over, and my Jin Kingdom is over! ”

"Her Royal Highness the princess is extremely worried, I think that Baili Yan must be ready to persuade my king first, and then lobby Zhiguo, and if my king can convince the eldest grandson, the possibility of the four countries joining forces at the same time is very great, if this situation is formed, more than forty percent of the trade in the Central Plains is controlled in our hands, as long as the Liang State is persuaded again, this matter can be done."

"But General Ji doesn't think it's strange, this incident happened at least three years ago, and Liang Guo has countless gold and silver every year, how can he not know. You say, does Liang Guo also have a share of this short catty? ”

Xihuan was suspicious, and Ji Jinsheng was cautious:

"Regardless of whether Liang Guo is involved in this matter or not, but at the moment, if Xian Guo is finished, Zhiguo, Changsun, Jin, Song, Xu, and Weiguo, who are close to Xian Guo, will be implicated. The worst result must be that all countries are angry with the Xian State and join forces to attack Xian, and then the king may turn against him to take revenge, and Her Royal Highness the princess's position is not easy to come by, and she will not be willing to see this result. ”

"Yes, seeing that the old immortal is getting older and older, and he will come out in a few more years, don't go wrong at this time. But how can this palace feel that something is wrong......"

"What does Your Highness mean?"

Xihuan stood up and frowned, thought for a long time, and said:

"Just now General Ji said that Zhi, Jin, Changsun, Song, Xu, Wei, Liang and Xian have close trade relations, and now there is a shortage of gold and silver, although Xian is the most affected, but other countries can not bargain, it seems that everyone suffers, then who benefits!

This is not a decimal, the total amount of gold and silver circulating in the Central Plains is tens of millions, and each one scrapes a tael or two, so how much gold and silver is needed, and these gold and silver must have a place to go.

And such a big deal, how can it be done by one person, there must be a prince behind it, otherwise such a huge wealth can only be taken away by a small number of people. ”

"His Royal Highness's words are reasonable, his subordinates didn't pay attention to them before, His Highness said this, it seems that everyone is victimized at the moment, it is completely unreasonable, or wait for Yin Yangjun to disperse the dynasty, please ask him to cut off the clues."

"My uncle only has money in his eyes, what can he know."

"Otherwise, there are often hidden mysteries in such sharp words, and we cannot see through them. Yin Yangjun has been walking in the mall for many years, and he knows everything about the goods in the Central Plains, and he may really be able to get a glimpse of it. ”

What Ji Jinsheng said is not unreasonable, capital will always flow to profiteering industries, and the higher the profits, the higher the capital enrichment. The capital mining area was found, and the root cause of the problem was found.

Walking out of the prince's mansion, it was still early, and Bai Liyan planned to wait for the end of the court meeting before going to the palace, so as not to be entangled in being pulled by officials at all levels for questioning.

Especially Qing Xijun, who has an official residence in the king's family, runs a lot of business, and lives in the king's family in August and September in a year, this time there is such a big thing, a few days ago he took his son into the palace to toss and ask for an explanation, before he only thought that this person was a little overlord, and in recent years, he has become more and more a heinous scoundrel, and it is nothing good to be entangled by him.

Walking on the street with Wei Qi and other escorts, looking at it as he walked, Bai Liyan was a little absent-minded. He suddenly thought of a question, a question that had been ignored all along.

At present, the composition of precious metals is not pure, whether it is 85 percent of the fineness, or 95 percent, there are some impurities, if the fineness of gold is always set at more than 90 percent, the remaining 89 percent of the impurity composition can make some articles.

Due to their unique stable properties, gold and silver are difficult to oxidize and acidify by conventional means, so they can only be dissolved with strong acids.

With the current means, it is not realistic to coat the surface of gold and silver with a layer of other substances for anti-counterfeiting.

If the texture of the precious metal is not pure, it means that the part containing impurities can be blackened by its oxidation properties.

For example, chemical dyeing is done for parts, using the oxidation characteristics of iron, copper and other elements, using chemical means to cook and dye, and plating a layer of oxide or chromium plating on the surface of the parts, so as to achieve the general anti-corrosion and anti-rust effect.

Because of its stable characteristics, gold and silver will not oxidize under normal conditions, but impurities are allowed, especially the artificially added elements are evenly distributed in the molten liquid after smelting, and one or more surfaces can be made by chemical boiling and dyeing.

It is not easy to clean with water, it is difficult to come off, and the color will gradually fade after a long period of circulation, but this wear process and the damage caused by corrosion can be clearly identified by the naked eye.

The corrosion time of aqua regia and nitric acid is slow and even, and the coloring of the surface is very easy to corrode under strong acid corrosion.

Thinking through this layer, Bailiyan swept away the haze in her heart for many days, and was in a good mood:

"Wei Qi, Ben Hou invited guests to the Xuan Pavilion for dinner today."

"Ahh Wei Qi was surprised, but in a blink of an eye, he thought that he could eat and drink, and he couldn't close his mouth happily.

The group came to the Xuanting Pavilion, and it was not yet noon, and the inside and outside of the Xuanting Pavilion were already full of guests.

The abundance of material life stimulated the development of food, and the way of life spread from the imperial palace and the palace gradually became a new business opportunity.
