w Zheng Lang smiled, Pang Ji may not be so kind. asked, "Brother Yanguo, what does he want to say?" ”

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

"What do you mean?"

"I think it's okay," Fubi said.

About before Fu Bi came, these two people had a detailed discussion, and Pang Ji said that Fu Bi was moved.

On the surface, it is possible, because Jiaozi is exquisitely made, costly, not easy to counterfeit, and quickly circulated throughout the country after printing. Some people also treasure Jiaozi. At the beginning, the cash of the copper coin was strictly one-to-one.

Kejiaozi is far easier to carry than copper coins, and the denomination is not large, not only can be used as a large number of commercial transactions, but also ordinary people can also be applied. The small number of issuances further determines its tension. Under the same amount, are the people willing to carry Jiaozi or heavy copper coins?

Therefore, the price of Jiaozi has risen slightly, and some people even pay a price of 105 to exchange copper coins for Jiaozi.

The policy of the Song Dynasty was to maintain sufficient coin circulation, and adopted the same system as the Tang Dynasty, which allowed the currency to be centralized and concentrated in the Jingshi region. Now Zheng Lang has transferred these coins to Lingnan together.

The currency of the Song Dynasty was still insufficient, resulting in the continued shortage of the Jingshi currency. The metal mined in just one year was far from meeting the monetary needs of the Song Dynasty, so Pang Ji wanted to issue another batch of Jiaozi.

Zheng Lang muttered, "Empty glove white wolf? ”

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

Zheng Lang lowered his head and did not speak.

He was thinking, thinking about the Song Dynasty in history.

The commercial development of the Song Dynasty was a good thing. But the coin is a history of serious suffering, a history of disaster.

With today's technology, it is very difficult to mine metal deposits, and the worst thing is that these metals are not only used for money, but also for foreign circulation. What is terrible is that the people are suffering and have a conservative concept of consumption. Likes to save money. It was stored in the cash cabinet to collect interest, and to prevent the cash cabinet from collapsing, so it was hidden at home. For example, Yang Liuxiu's wife's family has 100,000 yuan of money, ten money houses, and three generations of rich family members in Qingzhou. His ancestors used 100,000 yuan to town the family treasury, and three generations were rich, and the 100,000 yuan has never been touched. Not only Qingzhou hemp, but also Shouchun Wang, Da Jia Jiao, Longmen Li, and countless other famous households, all of which are based on 100,000 yuan. If you don't hide 100,000 yuan, you don't call yourself a wealthy family. The actual property is more than 100,000 yuan, and the liquid capital, houses, fields, workshops, shops, etc., often exceed more than 100,000 yuan. After the bank opened, these people still regarded the hidden money as a treasure in their own homes. I don't take it out. So for more than 100 years, the Northern Song Dynasty issued more than 300 million copper coins, but the money shortage has always puzzled the Song Dynasty.

Later, Cai Jing came up with a solution.

His salt law robbed some big families and businessmen, and the same is true of the money law, knowing the harm of Zhao Zhen's big money and iron money. It also minted a lot of big money and tin money, and carried out a predatory monetary policy. As a result, the Song Dynasty's currency was chaotic, and the money shortage remained unresolved.

Coupled with the fact that the imperial court recovered the money to the north, it was only then that Jiaozi appeared in Sichuan. The bottom is ordinary paper, and the pattern has the words of the house and wood figures, and the issuers of each hand are printed with their own secret marks. However, because it is cheap and easy to make. There are many counterfeiters, which leads to many lawsuits and lawsuits. Liu E is a native of Sichuan, and she doesn't want her hometown to be like this, so she asked Xue Tian to implement the official office. The printing is more exquisite, the impression is confidential, and it is not easy to counterfeit, but the amount of the hand over is huge, and it has always been two denominations with ten times. There were still people who forged it, but the losses were borne by the imperial court. In this process of circulation, the imperial court has suffered a lot of stuffy losses, and it can't be said that the dumb people eat Coptis chinensis, and there are hardships, who makes the country's money insufficient? Then the imperial court thought of a way, the Jiaozi was changed every two years, the front research came out of the printing mold, and the court had replaced the old Jiaozi with the new Jiaozi. and prepared a deposit of 300,000 yuan for Jiaozi, which made Sichuan Jiaozi circulate. But Zheng Lang estimated in his heart that in this process, the imperial court would lose at least more than 500,000 yuan.

But it depends on the fact that the cost of Jiaozi is far cheaper than copper money, a thousand times or even ten thousand times cheaper, and the cost of a piece of paper may not be as good as a copper, which is ten times. So when he arrived in Song Shenzong, he saw a serious shortage of money, and issued Jiaozi on a large scale, which led to the collapse of Jiaozi, and the value of Jiaozi depreciated twenty times during the time of Song Huizong.

But it's not serious.

Seriously, in the Southern Song Dynasty, the Northern Song Dynasty perished, which had little impact on copper production, most of the copper mines in the Song Dynasty were in the south, but the money circulated to the Jin Dynasty, although the total economic volume of the Southern Song Dynasty was reduced, it was still very considerable, and the money shortage was more serious. Song Xiaozong's Northern Expedition exacerbated the tension of coins.

Then it was issued on a large scale.

From the end of Shaoxing to the beginning of the eighth year of the main road, 10 million Jiaozi were issued, which was a normal issuance, and the exchange ratio was consistently more than 770 Wen (the actual money of the Song Dynasty was always only 700 tens of Wen, and one Qian was 1,000 Wen). In the early 20 years from the beginning of the main road to the beginning of Chunxi, 20 million jiaozi were issued, and the old jiaozi were still in circulation, depreciating to a consistent value of 750 wen. Later, the scale became larger and larger, and only 24 million Jiaozi were issued in the last three years of Chunxi, and at this time, the Jiaozi circulating in the market reached at least 500 million yuan. The demand for economic circulation in the Southern Song Dynasty must have exceeded 500 million yuan, but there was not enough metal currency to cash, and the credibility of Jiaozi fell seriously. The exchange ratio fell to the usual ratio of 700 Wen.

As the best Ming monarch in the Southern Song Dynasty, Xiaozong still did a very restrained job, one thousand to seven hundred, which was better than the situation in the late Northern Song Dynasty.

During the 20 years from Kaixi to Jiading, the issuance of Jiaozi reached 370,000 guan, which reduced the number of Jiaozi to 500 Wen. But it is not as powerful as Li Zong, only the fifth year of Shaoding, the sixth year of Shaoding, the fourth year of Jiaxi, and the sixth year of Chunyou, and the issuance of Jiaozi in four years is 1.79 billion yuan, and there is no record of other years, or the hard disk in my mind has not been copied, I don't know. However, it is estimated that the total amount of Jiaozi in the Song Dynasty at this time has reached more than 5 billion guan, and may even reach 10 billion guan.

At that time, the copper coins of the Jin Dynasty began to flow back to the Song Dynasty, and the two sides attacked, and Jiaozi fell to seventy Wen, and the old society could only exchange it for four full money, which was equivalent to 1,000 to 60 yuan. But it is already a miracle to be able to maintain this data, and it is estimated that the people of the Song Dynasty have also become numb. So Jiaozi collapsed completely.

Thinking of this, Zheng Lang said: "Absolutely not. The bank is running well, only two words, credibility. A batch of Jiaozi will be issued today, and more Jiaozi will be issued tomorrow, and once Jiaozi is flooded, the banks will collapse in all aspects. This is no small loss. If the banks were to pull apart nationwide, revenues would increase by a factor of four to five. ”

"Four or five times?"

"yes."

"Isn't it just 10% of the deed shares?"

"The further you go, the lower the returns. But those who participate in the future are all hesitants and may re-invest, which is a reward for the first mover. Seek wealth for the imperial court. This matter must not be leaked. As for the lack of currency, even if tens of millions of jiaozi are issued, the currency is still insufficient. There are gold, silver and copper as guarantees. It is money, and without sufficient gold, silver and copper guarantees, it is just a piece of cloth. I am also encouraging the people to raise silkworms and plant hemp on Guangnan Road, although the quality of silk silk is not as good as that of northern silk, it can also be used as quasi-currency. However, it will take two or three years to get through it, and the south can give back to the imperial court. As for the cover-up of the mellow theory, it doesn't matter, there is no need to cover it up, I will write a piece of writing to the court later. Make it clear. In any case, Jiaozi must not allow it to have any tendency to overflow. ”

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

It's baking soda.

It is impossible to work in production, so Zheng Lang still starts from the laboratory.

First, hydrochloric acid is made. This is placed in a laboratory and can react with sulfuric acid with salt to produce hydrochloric acid. However, sulfuric acid is expensive to make, and if you go to the second complicated step, hydrochloric acid will become sky-high. So the second method was changed, and the salt reacted with alum.

But salt is not pure salt at this time. There are even many harmful substances in it, but the people are used to eating them, and the stomach and intestines adapt to it, so they are not poisoned by it. This is especially true of alum.

There is only one way, find the right salt, the right alum, find a way to purify, and then go through the test again and again, which only took several years and cost a lot.

Then use dilute hydrochloric acid to react with limestone to make calcium chloride and carbon digasification, and use carbon dioxide to blow into the alkaline surface diluted with water for carbonization, which may be solved in a test class in later generations, but in the Song Dynasty, a lot of manpower and material resources were concentrated, and almost hundreds of thousands of dollars were smashed before and after, and nearly 100,000 times were tested, resulting in the death of two craftsmen due to mistakes, several injuries, and it took several years to get this baking soda out of the laboratory.

It does not yet mean victory, and it will only be a reluctant success when it can be mass-produced and the cost will be further reduced in the future. But if you want to yellow gunpowder officially energy production, there is one more thing, a detonator. There are no eyebrows at the moment.

However, it is a crucial step to take a step, and the related by-products, such as hydrochloric acid, calcium chloride, etc., have an industrial effect and can also be used as medicines. In the end, the success of the research of these substances one by one will not only degenerate the military, but also bring about a deformation in industrial production, medicine, and other aspects, and the significance is unimaginable.

"Okay," Zheng Lang said, a hint of reverie appeared in his eyes, not knowing if he could see that day.

Fortunately, Fu Bi didn't know where it was, he only knew the significance of the popularization of yellow powder.

Fu Bi and Gao Zhisheng successfully set up an alliance, and the two went to the place where Temo Road and the most Ning Mansion were connected to erect a stone monument. There are still affairs in the back, the covenant came into effect, the road should be repaired, and the road will be repaired, although it will be dangerous to Dali, but it will have a good effect on the economy of Dali, Liangguang, southern Sichuan and southern Tibet.

Zheng Lang handed over the matter of the road to Yu Jing to preside, and Zheng Lang did not participate in the alliance, all of which were presided over by Fu Bi.

There is a kind of love called letting go.

There is a kind of quietness called learning to delegate.

Zheng Lang left a lot of affairs, all of which were handed over to Yu Jing, Sun Kang, Song Xian, and Zhu Shoulong, and he took Zhou Xin to prepare to inspect the states and counties of Guangnan West Road again. However, at this time, Guangnan West Road is also full of talents, and aside from Yu Jing's lack of military and diplomacy, as a local official, it is still okay. The imperial court listened to Zheng Lang's advice again, and let Zhao Xun be the governor of Rongzhou, Guo Kui was the governor of Yizhou, Zhang Yu was transferred back to Shaanxi, but Yang Wenguang and Chong Ge stayed, and successively served as the governor of Guangnan West Road.

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

What to say about Zheng Diezhao, although hateful, is actually a joke, at this time, the regular forbidden army of Liangguang, including the 12,000 soldiers brought by Zheng Lang and Zhao Xun, only eight battalions of the forbidden army, plus the sacrifice of the Southwest Campaign, there are less than 9,000 people left at this time. Don't try to react to the Song Dynasty's 600,000 forbidden troops, even if you deal with the invasion of Jiaozhi, you are not sure of victory. It is necessary to raise the combat effectiveness of the native soldiers.

Another 100 officials were sent to Quang Nam East Road. Assist in the work of Quang Nam East Road, but the main purpose is to observe and learn. The basic conditions for the development of Guangnan West Road are much worse than those of Guangnan East Road. Among them, the ability of officials is the most important. Many officials and officials did not understand water conservancy at all, and Kong Zongdan made a small water conservancy irrigation project, which made the people of Yongzhou grateful to Dade. A winter of observation and study will lay some foundation for these 100 officials.

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

A very clever woman. When Zheng Lang was away, he often came to Zheng's house to take a walk, and when Zheng Lang came back. But he rarely came. As a result, it has not attracted the attention of others with suspicion so far.

Seeing that he didn't move, Zheng Lang's expression was a little sneering.

A Zheng Diezhao. almost caused a big storm, but fortunately, under the conscious suppression of all parties, the situation did not expand. Even so, he had to let Di Qing go back to the court to suffer. But Di Qing didn't seem to believe it, this is the depressing place.

If there is another one who does not move, hurry up and pack your luggage and go back to Zhengzhou.

Although the Wuyi clan is becoming more and more graceful and beautiful, Zheng Lang is close to each other, fortunately, there was no story in Yaoshan last time.

He bowed calmly.

Yue'er looked at her husband. Looking at Wu Yi again, the two of them had no abnormal expressions, and suppressed the suspicion in their hearts, and said, "Official, Sister Mingyue is here." I wanted to say something to the officials. ”

"I didn't move the lady, what's the matter?"

"My family wants to cooperate with the Fan family to develop more barren mountains and grow tea, I don't know if it's possible?"

"How is your family connected to the Fan family?" Zheng Lang asked, and quickly thought of the answer. Why, it hasn't moved, and the mountain still has the title of a national prince. It depends on the change, if he can stand in the Song Dynasty and make contributions to dealing with the Western Xia in the future, he is a family, and he can incarnate into the ranks of the real powerful families of the Song Dynasty. The Fan family has a lot of wealth and power, but it is very weak, so letting Yue'er be his concubine and wanting to join forces with the unmoved family is a mutually beneficial move.

It can't be said that it is wrong, in history, because the Fan family was a little weaker in strength and the wealth they obtained, they let other powerful people swallow all the properties of Fan Lou.

"The development of Guangxi and Guangzhou, there are mulberry hemp, commerce, and cane sugar, why only fancy Chashan?"

"The concubine heard about the covenant between the imperial court and Dali, and overhauled the ancient tea horse road, and the demand for tea must be very large. Moreover, if the two Guangzhous are successfully developed, the number of boats coming to Guangzhou will inevitably increase, and the boats will also carry more tea to sell to the big food. ”

"It's not a big food, it's sold farther away, but in the far west."

"Far West?"

"Byzantium, England, France, the Holy Roman Empire, Italy, etc."

"Are they big?"

"It's not easy to say, the countries stand side by side, there are several countries as strong as the Western Xia, small as Jiaozhi, such as my dynasty and the Khitan people are almost none. The civilization and economy are even worse than those of our dynasty, the advanced ones are similar to the Khitans, and the backward ones are similar to the Tibetans. Zheng Lang said lightly. However, he did not underestimate this Western country, and immediately began to have a drastic deformation. If history does not change, it will catch up by the time of the Ming Dynasty, which has left the Central Plains civilization far behind.

However, thinking of the bag of baking soda and the more than 200 students who studied physics in Taixue, Zheng Lang did not have a sense of urgency.

smiled and said, "You didn't move the lady, you are very smart." ”

Indeed, the expansion of the ancient tea horse road is successful, and the southern tea planting has great prospects, although if you want to achieve results, you must wait for a long time, from cultivating the mountains and mausoleums, to carrying the planting, to officially taking the tea, at least more than five years, if you want to be prosperous, it will take more than ten years.

The two said something lightly, didn't talk about anything else, and didn't take advantage of Yue'er's lack of attention, and looked at Zheng Lang with resentful eyes. Zheng Lang just lowered his head and drank tea, so he didn't see it.

Zheng Lang left Guizhou the next day, although it was still hot in the south, but it was much better than the inspection on Guangnan East Road, when it was really hot. In autumn, not only does the heat decrease, but the humid air also becomes refreshing.

Make this line less hard.

But this trip will be very long, in addition to Qiongzhou, Zheng Lang will inspect all the states and counties of Guangnan West Road, and even some of the prefectures.

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 deficiencies, with Guangzhou as the dividing line, there are many good ports along the way from Dengzhou to Guangzhou, which has nothing to do with the market shipping division, and many places do not have a city shipping division, but there are ports. In case of high winds, you can quickly evacuate to the port. This is also a constraint on the backward technology of ships, although the seafarers sailed far, and even the footprints of the Song people reached East Africa, but the ships could only sail along the coastline, fearing typhoons. This is also the reason why there are more supply points after the development of Ping An Supervision, and it is this supply point that makes the Song Dynasty successfully step into Oceania. Without these supply points, shipowners would not have dared to sail as far away as Oceania.

However, starting from Guangzhou to the west, there are few harbors that can shelter from the wind, which is one of them. Compared to sailing in the open sea, the distance of the safe haven is still better than that of the open sea. Not only are there few sheltered bays, but there is also a lot of sand on the coast in the North Bay area of Quang Nam West Road, which often leads to stranding. The Beibu Gulf area is not only sandy, but also has many sharp reefs under the sea, so there are relatively few sea boats.

In fact, it is still an economic problem, Qinzhou is relatively backward, the population is small, the profit is not large, and further north, there is Yushui instead, so the maritime trade can not develop. But the fact is that Qinzhou has a good delta, and the development prospects are very good.

However, one of the biggest drawbacks is that it is close to the cochin and is easily invaded by the cochin.

Just as he was thinking about Jiaozhi, the scout of the special service battalion quietly sent a message that Jiaozhi was preparing troops to move some troops north.

Since the departure of the Jiaozhi envoy, Zheng Lang mobilized more than 40 scouts from the special service battalion to infiltrate Jiaozhi to spy on intelligence.

Seeing this news, Zhou Xin asked worriedly: "Zheng Xianggong, it's not good." ”

Moving to the north, either to deal with Dali, or to Liangguang is not treacherous. Dali had just fought several small wars with the Song dynasty and was forced to sign three unequal treaties. Jiaozhi did not have to fight with Dali, so only Liangguang was left, and Di Qing was transferred back to the capital, and the timing 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 brings about his own destruction. If they dare not be tricky, I don't mind teaching them a hard lesson! "To be continued. If you like this work, you are welcome to vote for recommendation and monthly passes, and your support is my biggest motivation. m
