Sitting in the room, Bai Liyan thought a lot, so she asked Zong Botai first:

"Mr. Zongbo has a great talent, why didn't he go out back then, he had to wait until now, and wasted six years in vain."

Zong Botai smiled lightly and said:

"It's not a secret, in the next year, I traveled to various countries by practicing medicine for several years, and was invited by the Marquis of Lu when I passed through Zhiguo, so I came to Lingling to be a guest at the home of the Marquis of Lu, and asked for the pulse of Lian Hui, the concubine of the prince's side."

"Oh...... I remembered that it was the infertility of the prince's concubines. Why, is it still the case? ”

"Yes, but Uncle Zong is powerless, I thought that Master Hou was a skilled doctor and should be able to see the clues, but I didn't want to do it so far. Therefore, in the past few years, only Xihuan has given birth to two sons in the prince's mansion, and none of the other concubines are pregnant. ”

In the six years since the discovery of the infertility of the crown prince and concubine, only Xihuan has given birth to two sons, Jiang Tuo and Jiang Ping, and none of the other concubines are pregnant.

Now it is completely true that Xihuan poisoned it, but Guan Longxiang, Zong Botai, Luhou, and Xianwang secret agents have been tracking for six years, and neither found any medicine, nor poisoned or beaten, and the prince's several women are infertile, this probability is very low, and they can only use undetectable means.

"Since the Marquis of Lu is invited, why doesn't Mr. join the Hou of Lu, and have to dedicate his plan to the next and wait for six years?"

"Huh...... There are many people who are subordinate to the Lu Hou, and most of them are people who love money and have little righteousness, they can only be used to use their strength, not to be effective, and their words and deeds are neither beneficial nor beneficial.

As for Hou Ye, Hou Ye is pragmatic and frivolous, promoting agriculture and advocating industry and commerce, how can Hou Ye believe my three-inch tongue. ”

"Oh...... I understood that Mr. was worried that it would be useless to learn in his life, so he threw bricks and stones to wait for an epiphany. ”

"Don't dare, don't dare, I don't have any ambitions in this life, I just want to learn to be used by the master. When he heard about the life of the Hou Ye, Uncle Zong expected that the Hou Ye would be able to do a lot, so he worked hard here, just to be able to serve the Hou Ye. ”

"Sir, this is true!" Bailiyan said earnestly, quite moved in her heart.

"If Hou Ye does not give up, Uncle Zong is willing to calm the world for Hou Ye."

"With Mr.'s words, I, Bailiyan, will never live up to Mr.'s expectations." Turning his gaze to Zhao Anling, Bai Liyan said again: "But I don't know what Brother Anling's plans are." ”

Zhao Anling saluted and said:

"Anling is also willing to follow the Hou Ye and set the country and the country."

Baili Yan was overjoyed and instructed Guan Longxiang to get rice wine and wine utensils:

"Okay, if you can get the help of the two, why can't Xianguo try to be strong, please drink this cup with the two of you!"

"Master Hou, please!" Zongbo Taidao.

The three of them drank the wine in the bowl, and Zhao Anling said:

"The situation in the country, can Master Hou know?"

"When I was in Chenling, I have heard King Xian and Zhao Shuai say, yesterday night and just now I got the news of your uncle and Mr. Guan Long, there is a big difference between inside and outside, I came to Yongxing, but also to inspect the local and surrounding Tuntian, and I will rush to Zhongxing City to inspect in the near future, and then I have to clarify the treasury and taxes in various places, how to deal with it, and make careful arrangements, in addition, the new annexed people are the most tricky, and they should be given priority to resettlement."

"Then what is the Hou Ye going to do with the treasure he brought back this time."

Zong Botai asked, and Bai Liyan asked rhetorically:

"What does Mr. Zongbo think?"

"I think that if you can do without it, you don't need it first, once you start, if the countries raise the price of goods and raise the toll tax, it will do all kinds of harm to the salty country and not benefit."

"Sir is indeed very knowledgeable, the king has promised to seal the treasure after the gold and silver are recast, and only use part of it for reward, so that the Xianguo will not fall into the realm of tigers and rabbits. It's just that the current treasury is empty, and in the past few years, the king has aggressively promoted the new law, resulting in the four counties of Beihai, Dongyuan, Jiangdong, and Suidang, where the local heroes and strongmen have risen together, and the nobles cover the sky, and the treasury is becoming weak.

Mr. Zongbo and Brother An Lingxian have lived here for a long time, and they should be more transparent about the current situation, and they don't know if there are countermeasures to teach them to deal with emergencies? ”

At this time, Zhao Anling said with a smile:

"Uncle Zong has three dedications to Hou Ye, but I don't know if Hou Ye wants to hear it."

"As long as you can solve the current predicament, you can say it, and please ask Mr. Zongbo to give advice."

"Hehe, Master Hou has extraordinary knowledge, how dare he teach. In the lower upper middle and lower three strategies, the corresponding three results, the upper policy can be once and for all, the middle policy can solve the chronic disease, and the lower policy can solve the urgent need. ”

"What's the best policy?"

Bailiyan asked sincerely, and Zong Botai said categorically:

"Remint!"

"Shhh...... Re-minting is not trivial, and if you are not careful, not only can you not stabilize the copper coin, but you may also put it in with more gold and silver goods. ”

"But did the Hou Ye ever think of injecting gold and silver into the copper coins to forcibly boost the value of the copper coins of the Xianguo Kingdom."

"This ...... It's doable. But Mr. Zongbo didn't know anything. Copper coins have always been lead six copper four, the purpose is to prevent too much copper, some people smelt money to take copper, wait for the price of copper to rise, and sell copper to earn the difference.

Therefore, in order to improve the fire consumption of copper smelting with money, it has always been lead six copper and four coins. If you add gold and silver instead, if it is less, it cannot play a role in boosting the value of the currency and stabilizing copper coins, and if it is more, it can be used by traitors to refine gold and silver, so although this method is good, the disadvantages are obvious. ”

"Hou Ye is very knowledgeable and thoughtful, and what Uncle Zong wants to say is precisely this ratio of lead and copper. Only lead is usually added to coinage, but lead and copper are fusible and only need to be smelted once, so they can be separated by the introduction of air through the molten lead, which floats on top of the molten lead.

But if gold, silver, and tin were added to it, the cost of separating them would be multiplied, and it would be very easy to mint money, but it would be very difficult to extract gold, silver, and bronze, so it would be feasible! ”

"Well, that makes sense!" Bai Liyan nodded in affirmation of Zong Botai's suggestion.

At present, the alloy of lead and copper is separated, usually charcoal powder is used as the smelting agent, and the air is passed into the furnace by the aeration method, so that the molten liquid reacts with the air to form copper and lead oxides, and then charcoal is put into the charcoal to reduce the copper oxide and charcoal.

Since the density of lead is heavier than that of copper, the oxides of lead precipitate, and the reduced copper floats on the lead water, separating copper from lead, so that copper can be extracted.

Of course, the reaction between copper oxide and carbon produces carbon monoxide, and carbon monoxide and lead will also undergo a reduction reaction to form pure lead, and actually enter the process of repolymerizing copper, but the temperature required for this reaction process is much higher than the temperature of smelting copper-lead alloys, so there is no such problem.

In order to fully melt the two metals into a uniform alloy, it is necessary to fully smelt copper and lead, and the cost of such coinage is actually higher than that of copper obtained by smelting copper coins, so copper coins are often maintained in the ratio of lead six copper and four copper, so that the people can not take advantage of price fluctuations by extracting copper, and exchange copper coins to earn the difference.

The melting point of gold is equivalent to copper, silver is slightly lower, and the melting point of tin is lower than lead, and the cost of extracting gold, silver and copper through the above methods will become very high, and there is no technical basis for smelting and separating this alloy at present, and the chemical agent required will be more complex, there is no such acquisition of chemical smelter and industrial base, and every soil method separation means a fire consumption and more complex chemical smelting cost.

Moreover, the melting point of gold, copper and silver is similar, the inertness is stronger, there is no perfect chemical system, and it will be very difficult to separate the metals one by one if you want to use carbon as a reducing agent, which will inevitably produce a large amount of alloy slag. This undoubtedly increases the difficulty of smelting and makes it unprofitable to melt money and extract gold.

Of course, Zong Botai would not know such a detailed theory, most of them are based on the knowledge obtained from referring to classics and life practice, and with the convenience of Yongxing City's industry, it is not difficult to master basic metallurgical knowledge.

A variety of metal alloy coins can not only increase the value of the currency, but also eliminate illegal criminals, but the cost of the initial investment is extremely large, so the biggest problem of the best policy is the investment cost.

The central policy is relatively compromised, open sources and reduce expenditure, continue to expand the scale of the imperial court's tuntian, increase productivity, stabilize basic prices, reduce the circulation tax on daily necessities, and appropriately increase taxes, so as to feed half of the country west of the capital county.

This method has been effective for at least one year, and the main way to improve productivity is technology, without technology, you can only pile up manpower, and at present, there is neither enough education, talent, time resources to promote the technological industrial capacity, but also lack of manpower to expand the basic scale, so it is not urgent, far less than the first one.

As for the next policy, it can have an immediate effect, but it only delays the problem and cannot completely eradicate it.

It has been five years since the policy of supporting the people has been implemented in the western part of the prefecture, and the resumption of taxation has been immediately abolished, and the basic taxation has been resumed in Xianxi and Qiunan for next year's subsidy, and the taxes in various localities have been raised, and customs duties and transit taxes and fees have been imposed to forcibly replenish the national treasury.

This Fa Baili Yan obviously would not agree, so he could only choose between the upper and middle strategies. The middle policy is slow to work, but the analgesia is a lot, and the upper policy has strong instantaneous analgesia, but it is also the most problematic means.

The depreciation of copper coins in Beihai, Dongwon, Suidang, and Jiangdong was much worse than that of the capital, because the high productivity of agriculture and handicrafts in the capital county supported the market supply and currency value.

However, on the one hand, the magnates and magnates tightened the gold and silver, and on the other hand, let the Xianguo copper coins depreciate without going offline, and then they used the copper coins they obtained to exchange gold and silver for gold and silver in the capital counties where the copper coins were relatively strong, so as to earn the difference in price.

After the use of alloy coins containing gold and silver, the official treasury can use the alloy coins containing gold and silver as the benchmark to forcibly exchange copper coins from the hands of the powerful to squeeze out the water of malicious depreciation in the four counties, and at the same time, before the annual closing and settlement, the new currency will flow into the local markets one after another to replace the old currency.

The new currency will be more popular than the old currency because it contains gold and silver, and there will be no situation where the new currency is difficult to replace the old currency due to the change of the Qin currency, which will be conducive to the rapid expansion to the whole country in a short period of time, and stabilize the currency value and market sentiment.

But where did this huge amount of gold and silver come from?

If the ransom and dark money of the southern war are used, it will inevitably increase the supply of gold and silver in the market, and even depreciate, because the market and productivity are so large, and a sudden increase in the money supply will only lead to inflation, and more precious metals will be lost out of the country.

"The best strategy is good, but where can we raise so much money to mint coins without using our treasures?" Bailiyan asked.

"The treasury is empty, but the salt lord headed by the Marquis of Lu is not short of gold and silver, if it can get the support of the Marquis of Lu and the Marquis of Xuanting, the deficiencies can be lent out first."

Bai Liyan was also taken aback when he heard the news and borrowed money from Xuan Tinghou, Xuan Tinghou was a human spirit who only entered and could not be borrowed, and if he could lend it, he was not Qiao Lian.

"How can such a huge amount of money be easily lent out."

"Or you may pledge the treasure with gold and silver, and then withdraw it from the cash after the money is returned."

"This can't work, no, the treasures have all entered the Xianwang Tax Undertaking Division and the Inner Government, how can it be taken out as collateral."

It is impossible for King Xian to use his own money as collateral. The treasury is the treasury, the small treasury is the small treasury, the public and the private are different, and the king of Xian finally got a windfall by himself, where can he take it out.

Bai Liyan even thought that Zong Botai would also use the pearl as collateral to lend silver taels from Xuan Tinghou. If you can't pay back on time, Xuan Tinghou will not enthusiastically take away the pearl cultivation process.

But when I think about the details, there are really two sums of money to use.
