When he woke up, Li Zicheng took out the drawings again, he had already decided, crossed the water-powered engine and directly studied the steam engine, but there was no more mature steam engine like Watt on the drawings, they were all old-fashioned, and I don't know if it was good or not, let Wang Zheng study it first.

Li Zicheng copied a copy of the original drawing with a brush, and after preparing Wang Zheng to produce a bicycle, he asked him to conduct research in Lanzhou.

It's hard to write with a brush, and I'm not good at it, I can't help it, and now I don't have a fountain pen gel pen, not even a pencil......

Li Zicheng suddenly realized, since there is none, why not make it? He is ready to vigorously develop Lanzhou, without industrial manufacturing, how can Lanzhou develop? Xining has a variety of manufacturers such as perfumes, distilled spirits, soaps, chiming bells, leather clothes, carpets, wine, woolen sweaters, etc., what does Lanzhou have?

It seems that only the glass factory in Hutou Mountain was relocated, and there was a vanity mirror, but there were only two factories, which was really difficult to benefit the people, and it was necessary to increase the number of factories to benefit the ordinary people, and the people became rich, had spare money in their hands, and their purchasing power increased, which in turn could promote the development of industry and commerce.

Thinking like this, I rummaged through the materials again, and sure enough, I found the production drawings of pencils and a product closely related to people's lives: toothpaste and toothbrushes!

The production of toothpaste is more complicated, but the main raw materials are calcium carbonate, dicalcium phosphate, and silica, which can be found in ores.

According to the instructions on the drawings, toothbrushes are all plastic products, in this era, can not be directly produced, however, according to the level of modern industrial development, the brush head and handle can be made of bamboo, and the bristles are made of bristles, which are washed and cut neatly.

Li Zicheng vaguely remembered that the world's first toothbrush appeared in the court of the eleventh year of Hongzhi (1498 AD), the brush head and handle were bone, that was the court, regardless of the cost, if you want to produce a popular toothbrush, it is better to use cheap materials.

To manufacture toothbrushes, the most cumbersome thing is to drill holes in the brush head, as well as polish the brush head and handle smooth, which is handed over to the business, maybe the drilling machine, grinding machine will appear, the wisdom of the people is infinite, the key is how to guide.

Pencils, toothpaste, and toothbrushes, the three daily necessities, Li Zicheng does not plan to produce them himself, his main energy is still in military affairs, if everything is done by himself, not only time does not allow, but also is not conducive to the development of technology.

Since you don't produce it yourself, who will do it?

Li Zicheng suddenly remembered the banknotes that were about to be put on the market, and had an idea in his heart, Ao, and the Wu family in Jingyuan County, when the Heavenly Mandate Army entered Jingyuwei, the Wu family supported the Heavenly Mandate Army a lot, no matter whether Wu Shen sincerely supported the Heavenly Mandate Army, or was forced to show favor to the Heavenly Mandate Army due to the situation, he always had to give him a chance to really draw him closer to the allies of the Heavenly Mandate Army.

Therefore, Li Zicheng immediately picked up the brush and wrote a long letter to Wu Shen, in order to thank him for his support to the Heavenly Mandate Army, he would reward him with a copy of his important technology, and let him send reliable people to Lanzhou to produce and sell, and ensure that the profits were huge.

Li Zicheng sealed the letter and sent it to Jingyuan County on horseback, and the production drawings of toothpaste and toothbrushes were locked in a drawer and temporarily sealed.

………………………………………………………………

After countless times of publicity, Lanzhou City, for the Heavenly Mandate Army is about to issue paper money, it is already well known, since the Heavenly Mandate Army entered Lanzhou, did not issue an order, the people are looking forward to it, but this time, most of the people are uneasy, they are afraid of the Ming Dynasty's treasure banknote pit, even if there is no money left in the hand to exchange, but still sigh: the world has really changed!

The soldiers of the Mandate of Heaven in camouflage uniforms were almost all over the streets and alleys of the city, and under close surveillance, no one dared to complain in public, and there was no change in the city.

Although facing the possibility of being laundered, but leaving Lanzhou, I am afraid that I will not even be able to eat enough belly, besides, the people do not have much money to spare, and the paper money has little to do with them.

Under the coordination of Guo Shijun, the four largest merchants in Lanzhou, the Huang family, the Li family, the Liu family, and the Zhu family, all expressed their support for the paper money, and according to the strength of each family, the Huang family and the Li family each subscribed 10,000 yuan, and the Liu family and the Zhu family each subscribed 8,000 yuan.

The paper money that Guo Shijun prepared to put on the market in the first phase was only 50,000 yuan, excluding the 36,000 yuan pledged by the four companies, Li Jibu's military salary was 1,200 yuan, and the city officials' salary was 200 yuan, and the remaining banknotes were only more than 10,000 yuan.

Huaxia Bank did not have the pressure of a run, in addition to the 120,000 taels of silver in stock, there were also 36,000 taels of silver subscribed by the Huang family, the Li family, the Liu family, and the Zhu family.

In other words, the 36,000 yuan banknotes in the hands of the four major merchants were exchanged for silver from Huaxia Bank, and when they received the banknotes, they also delivered the same value of silver to Huaxia Bank.

At present, Huaxia Bank has 156,000 taels of silver in stock, which is three times the amount of paper money.

Li Zicheng was also surprised, between this change of hands, Huaxia Bank's inventory increased by 36,000 taels, what is the difference between this and the white wolf with empty gloves? However, only by maintaining the credibility and value of the banknotes can Huaxia Bank truly become the ATM of the Mandate of Heaven!

Economists are great, they don't create products like scientists, but they can make money work in unexpected ways.

On 5 September, paper money was officially circulated in the market, and at the same time, Huaxia Bank opened the exchange business between silver money and paper money, and the people could exchange their paper money for city silver money, and they could also exchange silver money for paper money.

Guo Shijun estimated that at the beginning, the people did not trust paper money very much, or mainly to exchange silver money, most of the windows of Huaxia Bank were used to exchange silver money, leaving only one window for the people to exchange paper money.

Since about the beginning of the hour, Huaxia Bank has begun to get busy, and the small merchants and vendors who have been exchanging silver money one after another have lined up at the door of the bank, all of which are exchanging the banknotes received today.

In front of the gate of Huaxia Bank, the soldiers of the Heavenly Mandate Army were loaded with guns and ammunition, quiet as iron, and only a small flag officer walked back and forth, "Don't crowd, all line up, the bank has silver......"

Huang Zhang, who was exchanged for copper coins, was smiling, he was the first customer of Huaxia Bank, and he also received a reward of two cents, "Hehe, you can really exchange copper coins, and there are rewards!" He put the copper coin he had just exchanged into his mouth and took a bite, "Well, really, really!" ”

Someone flashed envious eyes, if it wasn't for strolling around the market and coming to exchange it earlier, maybe the two pennies would be their own......

To exchange for silver, basically are ordinary small traders, there are also sell their own vegetables, mutton, eggs, there are not many banknotes in hand, fortunately Guo Shijun has been prepared, not only prepared a large number of copper coins, but also silver into one or two, exchange, very convenient, the speed is also very fast.

An old farmer standing at the end of the line muttered: "Since it can be exchanged, why is it so cumbersome, and it is easy to trade directly with silver money, and you can save queuing here......"

The little flag officer who was in charge of maintaining order heard the voice, glared at him, and said sharply: "This is something that the Metropolitan Governor and Lord Guo are thinking about, what do you know?" If it hadn't been for the Mandate of Heaven army giving you food and distributing the land, I don't know where you would have gone to guard the wheat......

The old peasant was so frightened that he hurriedly turned his wrinkled old face away, not daring to look at the fierce little flag officer.

At lunchtime, the people queuing up outside Huaxia Bank to exchange money gradually dispersed, and the bank was temporarily closed and entered the lunch break.

Vice President Cui Wenxuan immediately reported the morning's results to Guo Shijun.

Li Zicheng happened to be in the Gold and Silver Division, and when he saw Cui Wenxuan coming over in a hurry, he said casually: "Wenxuan, how many banknotes were recovered in the morning?" ”

Cui Wenxuan hurriedly arched his hand and said: "Back to the Grand Governor, a total of 1,328 yuan and six corners and four points!" ”

"More than a thousand? Luckily, not too much! Li Zicheng did not know the daily trading volume of the Lanzhou market, but there were nearly 40,000 yuan in the market, and more than 1,000 yuan was recovered. ”

Li Zicheng himself laughed, if someone came to the bank to exchange banknotes, how could there be a long queue in front of the bank? Wouldn't it be easier for people to exchange directly with each other?

"Back to the Grand Duke, for the time being...... No, so the villain temporarily changed the window where it was originally intended to exchange banknotes to exchange silver coins! ”

"It's good that this can increase the speed of exchange, and the people will have less worries in their hearts!" Li Zicheng looked at Guo Shijun again, "Shijun, continue to strengthen the propaganda of paper money, focusing on the order of the Governor's Office!" ”

"Yes, Metropolitan Governor," Guo Shijun said, "the men sent by his subordinates continued to carry out propaganda at intersections, market squares, and residential areas, and re-posted a lot of propaganda slogans, and silver money and paper money were exchanged freely; No one shall refuse to accept banknotes or money; The price of goods shall not be increased, and those who violate the order will be severely fined! ”

"Hmm!" Li Zicheng nodded, he was not interested in the internal management of the bank for the time being, so he handed it over to Guo Shijun, then got up and left the gold and silver division and returned to the home of the back office.

In the afternoon, Li Zicheng changed into ordinary people's clothes and was about to go to the market, but He Xiaomi came to report: "Metropolitan Governor, Lord Wang Zheng is here from Xining, and he is waiting outside the Metropolitan Governor's Mansion to ask to see him!" ”

"Wang Zheng?" Li Zicheng laughed, "It's not slow!" I changed my clothes first, and then arrived, and Xiaomi led Mr. Wang into the study to serve tea! ”

"Yes, Grand Duke!" He Xiaomi said yes and ran away.

When Li Zicheng came to the study, Wang Zheng was drinking tea, compared with the last time, Wang Zheng looked older, his hair was seriously gray, more white and less black, and the muscles on his face were obviously relaxed.

Li Zicheng knew that during this time, Wang Zheng must have been worried a lot about the bicycle, which was the most meaningful time in Wang Zheng's life, and it was also the most difficult time.
