W Zheng Lang smiled, Pang Ji might not be so kind. He asked: "Brother Yanguo, what exactly should he say?"

"Pang Chunzhi wants to expand the number of Jiaozi."

"What do you mean?"

"I think that's OK," Fu Bi said.

These two people had a detailed discussion before Fu Bi came, and Pang Ji persuaded Fu Bi.

On the surface, it is OK, because Jiaozi is exquisitely crafted, expensive, and not easy to imitate, and it is quickly circulated all over the country after printing. Some people even treasure Jiaozi. The strict cashing of Jiaozi and copper coins is one to one.

Kaoruzi is much easier to carry than copper coins, and has a small denomination. It can not only be used as a commercial transaction with large quantities, but also applicable to ordinary people. The small quantity issuance further determines its tension. Under the same quantity, are the people willing to take Jiaozi or heavy copper coins?

Therefore, the price of Jiaozi rose slightly, and some people even offered a price of 1005 to exchange copper coins for Jiaozi.

The policy of the Song Dynasty was to maintain enough currency circulation, and adopted the same system as the Tang Dynasty, so that the currency centralization and concentrated it in the capital. Now Zheng Lang transferred these coins to Lingnan together.

The Song Dynasty's currency was still insufficient, resulting in the continued lack of money in the capital. The metal mined in one year was far from meeting the Song Dynasty's currency demand, so Pang Ji wanted to issue another batch of Jiaozi.

Zheng Lang murmured: "Get out of nothing?"

"No, Xingzhi, think about the backward Jiaozi in Bashu, which is indeed a disadvantage..."

Zheng Lang lowered his head and refused to speak.

He was thinking about Jiaozi of the Song Dynasty in history.

The development of business in the Song Dynasty was a good thing. But coins were a serious history of suffering and disaster.

With current technology, it is very difficult to mine metal deposits. What is serious is that these metals are not only used as currency, but also circulate to foreign countries. What is serious is that the people suffer, have conservative consumption concepts, like to store money, and have to collect interest in money, and they also need to prevent the money from falling and quarreling, so they are hidden in their homes. For example, Yang Liu Xiucai's wife has 100,000 yuan in money houses, and the family of Ma Yuanwai of Qingzhou has been rich for three generations. His ancestors have 100,000 yuan in money, and the three generations have become richer, but the 100,000 yuan in money has never moved one son.

Only the Qingzhou Ma, there are also the Shouchun King, Jiao Jiao, Longmen Li, and countless famous big households, all of which are hidden money based on the base of 100,000 yuan. If they do not hide 100,000 yuan, they are not called wealthy households. The actual property is more than 100,000 yuan. The liquid funds, houses, fields, workshops, shops, etc., often exceed one million yuan. After the bank was opened, these people still regarded these hidden money as their own treasures for housekeeping. They did not take it out. Therefore, more than 300 million yuan of copper coins were issued for more than 100 years of the Northern Song Dynasty, but the shortage of money has always confused the Song Dynasty.

Later, Cai Jing came up with a solution.

His salt method was used to plunder some big merchants and merchants, and the same was true for the money method. Even though he knew the harm of Zhao Zhen's big money and iron coins, he also cast a lot of big money and tin coins and implemented a predatory monetary policy. As a result, the currency chaos in the Song Dynasty was chaotic and the money shortage was still not resolved.

In addition, the imperial court recycled the money to the north, Jiaozi appeared in Sichuan. The briefing was ordinary paper, with patterns with wooden characters and shops, and each Jiaozi issuer printed their own secret notes. However, because it was easy to make and there were many counterfeits, it led to many lawsuits and lawsuits. Liu E was from Sichuan and did not want to do this in her hometown, so she let the transfer commander Xue Tian implement the official office. The printing was more exquisite, the impression was kept confidential, and it was not easy to counterfeit, but the amount of Jiaozi was huge during the implementation, and the denominations of Zheng and Shiguan were both forged, but it was damaged.

The court lost the responsibility. During this process, the court suffered a lot of depressed losses, but it was hard to say that the mute eats coptis chinensis and has difficulty saying that the country's coins were insufficient? Then the court thought of another solution, Jiaozi changed every two years, and the printing model was believed to be accepted in the previous study, and the court had already exchanged the old Jiaozi for the new Jiaozi. It was also prepared for Jiaozi, which made the Sichuan Jiaozi circulating. But Zheng Lang estimated that in this process, the court lost at least 500,000 yuan.

But it depends on that Jiaozi's cost is much cheaper than copper coins, one thousand times or even ten thousand times cheaper, and a piece of paper may not cost as much as a copper coins, which is ten cents. So when Song Shenzong came to see a serious shortage of money, and the large-scale issuance of Jiaozi, which led to Jiaozi's collapse. Jiaozi's depreciation during Song Huizong's reign was twenty times depreciated.

But it's not serious yet.

The serious reason is that during the Southern Song Dynasty, the demise of the Northern Song Dynasty had little impact on copper production. Most copper mines in the Song Dynasty were in the south, but the money was mostly circulated to the Jin Dynasty. Although the total economic output of the Southern Song Dynasty narrowed, it was still quite considerable, and the money shortage became even more serious. Song Xiaozong's northern expedition increased the tension in coins.

Then, it is released on a large scale.

The 10 million Jiaozi was issued in the eighth year of Shaoxing to the Gandaochu. This is a normal issuance. The exchange ratio was always more than 770 million yuan (the actual money in the Song Dynasty was only 700 million yuan, and one sausage was only 1,000 yuan). During the 20th year of the Jindaochu to the Chunxichu, 200 million Jiaozi was issued, and the old Jiaozi was still in circulation, depreciating to always more than 750 yuan. Later, the scale became larger and larger, and 24 million Jiaozi was issued in the late Chunxichu. At this time, the Jiaozi circulated on the market reached at least 500 million yuan. The demand for economic currency in the Southern Song Dynasty was definitely more than 500 million yuan, but there was not enough metal currency to cash in, and Jiaozi's reputation fell seriously. The currency ratio fell to always more than 700 yuan.

As the best wise ruler of the Southern Song Dynasty, Xiaozong was still very restrained, one thousand to seven hundred, better than the situation in the late Northern Song Dynasty.

Ningzong began to come to the fore. In the 20 years since Kaixi to Jiaoding, the issuance of Jiaozi reached 37,000 guan, which reduced Jiaozi to Yiguan Dui 500 guan. But it was not as good as Lizong. It was only the fifth year of Shaoding, the sixth year of Shaoding, the fourth year of Jiaoxi, and the sixth year of Chunyou, and the fourth year of Jiaozi was issued in four years. There was no record of other years, or the hard drive in my mind was not copied, which was unknown. However, it is estimated that the total amount of Jiaozi in the Song Dynasty had reached more than 5 billion guan, and it might even reach 1.0 billion guan.

At that time, the copper coins of the Jin Dynasty began to flow back to the Song Dynasty. The two sides attacked each other. Jiaozi fell to 70 ci and could only exchange for four ci and enough money, which was equivalent to less than 1,000 to 60. However, it was a miracle to be able to maintain this data. It was probably a numbness to the people of the Song Dynasty. So Jiaozi collapsed completely.

Thinking of this, Zheng Lang said: "No. The bank is operating well, with only two words, and its credibility. A batch of Jiaozi is issued today, and more Jiaozi will be issued tomorrow. Once Jiaozi is flooded, the bank will collapse in all aspects. This is not a small loss. If the bank is opened nationwide, its income will increase by four to five times."

“Four to five times?”

"yes."

"Is it not only ten percent of the shares?"

"The future will be lower. But those who participate in the future will be hesitant, and may invest again. This is a reward for the pioneers. This is a reward for the court. This matter cannot be leaked. As for the insufficient currency, even if tens of millions of Jiaozi is issued, the currency is still insufficient. With gold, silver and copper as a guarantee, it is a piece of cloth. I am also encouraging the people to raise silkworms and plant hemp on Guangnan Road. Although the quality of silk in the north is not as good as silk in the north, it can also be regarded as a quasi-currency. However, it will take two or three years to survive. The southern convenient can feed back to the court. As for the cover of the melancholy theory, it is okay, and there is no need to cover it. I will write a memorial to the court later to write this matter. In any case, Jiaozi cannot make it proliferate or disaster."

Fu Bi didn't understand this very well, so he said another thing: "This is something that your student Shi Heng brought, and there is also a letter."

It's baking soda.

Working production is impossible, so Zheng Lang still started from the laboratory.

First, make hydrochloric acid. This is placed in the laboratory and can be used to react with sulfuric acid and salt to produce hydrochloric acid. However, when sulfuric acid is expensive, then perform a complicated second step, hydrochloric acid will become a sky-high price. So it is changed to the second method, and salt and alum react.

But at this time, salt is not pure salt. There are even many harmful substances in it, which are only used to people's appetites, and the stomach and intestines are adapted to it and will not be poisoned by it. This is even more so for alum.

There is only one way, find the right salt and the right alum, find every way to purify it, and then go through repeated experiments. It took several years and took a lot of money.

Then, dilute hydrochloric acid reacts with limestone to make calcium chloride and carbon dioxide, and carbon dioxide is blown into the alkaline surface diluted with water for carbonization. It is possible to solve a problem in a test class in later generations. However, in the Song Dynasty, a lot of manpower and material resources were concentrated, and nearly tens of thousands of dollars were spent. Nearly 100,000 times of experiments were tested, resulting in two craftsmen's death due to mistakes and several people were injured. It took several years to get the baking soda out of the laboratory.

It cannot represent victory. In the future, it must be able to produce large-scale products and further compress costs. Only then can it be said to be a barely successful success. But if you want to produce the official energy of yellow gunpowder, there is one thing, a detonator. You still have no idea at the moment.

However, taking a critical step, and related accompanying products, such as hydrochloric acid, calcium chloride, etc., have industrial effects and can also be used as medicines. In the end, these substances were successfully studied one by one, which not only caused military degeneration, but also caused industrial production, medicine and other aspects to be degeneration. The significance is unimaginable.

"Okay," Zheng Lang said, with a trace of reverie in his eyes, wondering if he could see that day.

Fortunately, Fu Bi didn't know what was going on, he only knew the meaning of the popularization of yellow gunpowder.

Fu Bi and Gao Zhisheng successfully set up an alliance agreement. The two went to the junction of Temo Road and the Sining Mansion to erect a stone tablet. There were affairs behind it, and the alliance took effect. The road was to be built. Although it would pose a danger to Dali, it would have a good effect on the economy of Dali, Guangdong and Guangxi, southern Sichuan and southern Tibet.

Zheng Lang handed over the road to Yu Jing, and Zheng Lang did not participate in the alliance, and Fu Bi was all hosted.

There is a kind of love called letting go.

There is a kind of quietness called learning to delegate power.

Zheng Lang left a lot of affairs and handed over to Yu Jing, Sun Kang, Song Xian, and Zhu Shoulong. He took Zhou Han to inspect the prefectures and counties of Guangnan West Road again. However, at this time, Guangnan West Road was also full of talents. Apart from Yu Jing's military shortcomings and diplomatic shortcomings, it was still possible to be a local official. The court followed Zheng Lang's opinions and asked Zhao Xun to be the governor of Rongzhou, Guo Kui as the governor of Yizhou, and Zhang Yu was transferred back to Shaanxi, but Yang Wenguang and Zhong Yan stayed and served as the commander of Guangnan West Road one after another.

These generals stayed not only to plan the Meishan barbarians in the future, but also to prevent Jiaozhi and preside over the winter training of the local soldiers in Guangnan.

Although it is abominable, it is actually a joke. At this time, the regular imperial guards in Guangdong and Guangxi, including the 12,000 soldiers brought by Zheng Lang and Zhao Xun, were only eight battalions of imperial guards. In addition to the sacrifice of the Southwest Battle, there were less than nine thousand people left. Don’t make a reaction to pay the 600,000 imperial guards of the Song Dynasty, even if you deal with the Jiaozhi invasion, you are not sure to win. The combat effectiveness of the local soldiers must be improved.

Another hundred officials were dispatched to Guangnan East Road to assist in the work of Guangnan East Road, but the main purpose was to observe and learn. The basic conditions for Guangnan West Road were much worse than those of Guangnan East Road. Among them, the abilities of officials were the most important. Many officials and officials did not understand water conservancy at all. Kong Zongdan had a small water conservancy irrigation project, which made the people of Yongzhou grateful. One winter observation and study would lay some foundation for these hundred officials.

Just as he was about to leave, he came to his house as a guest.

A very clever woman. When Zheng Lang was away, she often came to Zheng's house for a walk, but when Zheng Lang came back, she rarely came. Therefore, it has not attracted the attention of others so far.

Seeing that the family was not moved, Zheng Lang's expression was a little embarrassed.

Zheng Diezhao almost caused a big storm. Fortunately, under the conscious suppression of all parties, the situation did not escalate. Even so, he had to let Di Qing return to the court to suffer. But Di Qing seemed to not believe it, this was the place of depression.

If another person is not moved, pack your luggage and get back to Zhengzhou.

Although I didn't move my family became more and more graceful and beautiful, Zheng Lang felt unhappy. Fortunately, there was no story in Yaoshan last time.

Wuyi gave a bow calmly.

Yue'er looked at her husband and looked at Wu Yi again. Both of them had no abnormal expressions. They suppressed their suspicion and said, "Officials, Sister Mingyue is here. I want to tell someone something to the official."

"What's wrong with my wife?"

"My family wants to cooperate with the Fan family to develop more barren mountains and plant tea. I wonder if it is possible?"

"How did your family connect with the Fan family?" Zheng Lang asked, and soon thought of the answer. Why did you not move to Jishan still have the title of Duke? It depends on your change. If you can stand up in the Song Dynasty and make contributions to Xixia in the future, he will be a family and become a real powerful family in the Song Dynasty. The Fan family has a lot of wealth but is very weak, so they let Yue'er be his concubine and want to join forces with Wuyun's family, which is a mutually beneficial move.

It cannot be said that it is wrong. In history, the Fan family has become a little weak and has gained great wealth, allowing other powerful people to swallow all the industries in Fanlou.

"Why do you only look at Tea Mountain in Guangdong and Guangxi, including mulberry, hemp, commercial, and sugar?"

"I heard that the court had a pact with Dali and overhauled the ancient tea-horse road, and the demand for tea must be very high. Moreover, if Guangdong and Guangxi are successful in development, the number of foreign ships coming to Guangzhou will inevitably increase, and the foreign ships will carry more tea and sell them to Dashi."

"It's not big food, but the place where it sells farther, but the place that is far west."

"The extreme west?"

"Byzantine, England, France, the Holy Roman Empire and Italy."

"Are they big?"

"It's hard to say that all countries are united. There are several countries that are as powerful as the Western Xia, as small as Jiaozhi, and almost no one like our dynasty and the Khitan. Civilization and economy are even less than our dynasty. The advanced ones are similar to the Khitan, and the laggard ones are similar to the Tubo." Zheng Lang said lightly. However, he did not underestimate this Western country and immediately began to undergo drastic changes. If history did not change, it would catch up in the Ming Dynasty, and the Qing Dynasty had already left the Central Plains civilization far behind.

However, when thinking of the pack of baking soda and more than 200 students studying physics in the Imperial Academy, Zheng Lang did not feel urgency.

He smiled and said, "You are very smart if you haven't moved your wife."

Indeed, the expansion and renovation of the ancient Tea-horse Road has been successful, and tea planting in the south has great prospects. Although it is necessary to wait a long time to achieve results. From the cultivation of mountain mausoleums to the carrying of planting, to the formal collection of tea, it will take at least five years. If you want to produce a lot of food, it will take more than ten years.

The two said something lightly, without talking about anything else, and Wuyishi looked at Zheng Lang with resentful eyes while Yue'er was not paying attention. Zheng Lang just lowered his head to drink tea and pretended that he didn't see it.

The next day, Zheng Lang left Guizhou. Although the south was still hot, it was much better than the inspection on Guangnan East Road. It was then that the heat was really hot. After autumn, not only did the heat decrease, but the wet air also became refreshing.

This makes this job less difficult.

But this journey will be very long. In addition to Qiongzhou, Zheng Lang will inspect all prefectures and counties on Guangnan West Road, and even some restricted states.

In mid-October, Zheng Lang came to Qinzhou.

Qinzhou can also be used as a good port, and some sea ships come to trade. However, there are many shortcomings. With Guangzhou as the dividing line, there are many good ports along the way from Dengzhou to Guangzhou, which have nothing to do with the Market Shipping Department. There are no Maritime Traffic Department in many places, but there are ports. If there is strong wind, you can quickly enter the port to take refuge. This is also the constraint of backward ship technology. Although sea passengers sail far away, even the footprints of the Song people arrived in East Africa, ships can only sail along the coastline and are afraid of typhoons. This is also the reason why there are more supply points after the development of Ping An Supervision. It is these supply points that have successfully made the Song Dynasty sea ships step to Oceania. Without these supply points, the ship owners would not dare to sail to such a faraway place in Oceania.

However, starting from Guangzhou to the west, there are fewer harbors that can shelter, which is one of them. Compared with long-sea navigation, the distance of the shelter is better than that of long-sea navigation. Not only are there fewer shelters, but there are more sand and soil on the coast of the North Bay area of ​​Guangnan West Road, which often leads to stranding. The Beibu Gulf area not only has sand and soil, but also many sharp reefs under the sea, so few sea boats come.

In fact, it is still an economic problem. Qinzhou is relatively backward, has a small population, and does not make much profit. Going northward, it is replaced by turbulent water, so maritime trade cannot develop. But the fact is that Qinzhou has a good delta and its development prospects are very beautiful.

However, one of the biggest disadvantages is that it is close to Jiaozhi and is prone to Jiaozhi invasion.

While thinking about Jiaozhi, the scout from the special agent camp quietly sent a message saying that Jiaozhi was preparing troops and moving some troops to the north.

After the self-selected messenger left, Zheng Lang mobilized more than 40 scouts from the special agent camp to sneak into Jiaozhi to spy on information.

Seeing this news, Zhou Heng asked worriedly: "Mr. Zheng, it's not good."

Moving northward, either dealing with Dali or being unkind against Guangdong and Guangxi. Dali had just fought several small-scale wars with the Song Dynasty and was forced to sign three unequal treaties. Jiaozhi did not have to get into evil with Dali, so only Guangdong and Guangxi were left. Chacha Di Qing was transferred back to the capital, and the time was good.

Zheng Lang suddenly thought of Di Qing's words, Zheng Xianggong, think about how the Tang Dynasty defeated Goryeo. Thinking of this, he was full of confidence and said, "Yelang is arrogant and destroys himself. If they dare not be weird, I don't mind giving them a harsh lesson!" To be continued.
