From a rational point of view, Xu Shao's death is still good for Yuan Yao, and someone will definitely find out the cause of his death, so that Yuan Yao's reputation will spread all over the world, and there is no need to deliberately publicize it.

But emotionally speaking, Yuan Yao still felt very sorry, this was the first celebrity of the Three Kingdoms to die he faced, which couldn't help but make him realize that this kind of thing might happen in the future, especially the high-risk profession of military generals.

I remember that when I played the Three Kingdoms game in the future, if I accidentally killed a famous general, he would re-read the file, or simply abandon the file and replay, otherwise he would regret it until the unification of the Three Kingdoms.

I'm afraid I can't be so willful now......

"Hey, if he is willing to stay in Danyang Academy and reopen the Yuedan Review......" Yuan Yao thought with some regret.

Regret is regret, work still has to work.

The reform of the reform, the expedition of the expedition, Yuan Yao also has to go back to Jing County to get the paper money matter done.

The engraving of the banknote has been made, and the engravers have not dismissed, but have raised the requirements to design the next edition of the banknote engraving.

Paper mills and mints have been built, and printing and banknote technology has been activated, waiting for the first batch of paper to be produced.

With stamps and engraving, and after the popularization of paper, engraving printing was almost a natural technique, so there was no difficulty.

After several days of patient waiting, the first batch of banknotes in history was finally printed in the Jingxian Mint.

Stroking the red banknotes, Yuan Yao was excited, when the implementation of the grain-based currency system is completed, and the grain output in the territory is collected into the grain bank, then these banknotes are equivalent to piles of grain, and what can Cao Cao Tuntian do at that time, the two are no longer at the same level in terms of resource utilization.

At that time, Yuan Yao will not be afraid of anyone, at least from the logistical point of view, it will increase his self-confidence.

The name of the banknote is "grain money", and the main function of the future grain standard currency is now the income and expenditure voucher of the grain bank, and it is used to pay wages to the peasants hired by the farmer, and then let them go to the grain bank to exchange grain freely.

The purpose of this is to save food; Second, it is necessary to gradually establish the credibility of the grain bank.

When everyone knows that they can really exchange grain at the grain store with paper money, some people will voluntarily deposit the grain in the grain store, which can not only reduce the loss of stored grain, but also eat interest.

Grain money or grain can also be exchanged for a kind of "grain stamp" at the grain bank, which is a voucher for regular interest, with reference to the silver stamps of later generations, but with a limited date, it cannot be exchanged for grain until the date on the grain stamp, at least not in the grain bank, and the grain bank does not interfere in private transactions.

As for the arbitrary conversion between regular and current accounts, we will have to wait until later, and we will not consider opening this function directly for the time being.

If we want to turn grain money into a formal grain standard currency, we must decide the amount of grain to be issued and the scope of use according to the stock of grain principal, which requires the grain bank to be established and on the right track, so that grain money can be gradually used in official and controllable channels such as salt, iron, and taxation, and finally pushed to the people in an all-round way.

If there is a sudden and unrestrained full liberalization, and there is not so much food, inflation is a trivial matter, and financial collapse is a big trouble, so it has to be upgraded step by step like playing a game, and Yuan Yao's task is to speed up this process.

The amount of grain money is completely based on the weights and measures of grain use, that is, 1 Hu = 10 buckets = 100 liters.

Fortunately, it is a decimal system, if it weighs 1 catty = 16 taels like the Han Dynasty, then Yuan Yao will be crazy.

The value of grain is based on the current staple food corn, which is the same as the value of rice in the south, and if it is converted into copper coins, it is about 1 liter of grain = 2.2 copper coins.

The face value of the unit is set according to the law of one, two and five according to the experience of later generations - that is, one liter, two liters, five liters; One bucket, two buckets, five buckets; 1 Hu, 2 Hu, 5 Hu, 10 Hu, 20 Hu, 50 Hu, 100 Hu, a total of 13 denominations.

Because it is the same number as the thirteen states of the Han Dynasty, the design of the banknote is based on the theme of the thirteen states.

As for the face value of the regular food stamps, the same as the cheques of later generations, the amount is written on the spot, so it is not in this category.

Of course, the banknotes at this stage are still very rough, but because of the technical monopoly of paper, there is no fear of being imitated.

Xuan paper must be sold as a commodity, but the paper used to print banknotes is a special paper, and this Yuan Yao will never make more, let alone sell it.

The paper mill is still clone in production, so there is no need to worry about technology leakage.

A total of 13,000 pieces of grain money were printed in the first batch, with 1,000 pieces of 1,000 pieces in each of the 13 denominations, with a total value of 188,880 yuan, which can be taken by one person with one hand. This is the production of mint banknotes in one day, and only more than 30 catties of paper are used.

Yuan Yao planned to print for a month, that is, the face value of more than 5 million hu, and the consumption was less than 10 stone paper, but it was enough for Lu Su to use for a long time.

In this way, the monthly output of 3,000 stones of the paper mill is almost useless, and Yuan Yao plans to use these papers in the Danyang government first, and by the way, advertise them first, and then put them on the market according to the progress of the establishment of the grain bank.

Of course, you have to have food money to be eligible to buy it.

After getting the banknotes, the rest was handed over to Lu Su, and Yuan Yao left Jing County to find Liu Ye for the sake of Chasang.

After activating the "Xuan Paper" technology in Jing County, Yuan Yao once wanted to experiment with whether he could activate the silk weaving technology of Nanjing Yunjin and the roasted tea technology of Huangshan Maofeng.

But after understanding, he found that the tea mulberry industry in Danyang County is now almost zero, which means that there are no basic raw materials for silk and tea, and even if the technology is activated, it is useless.

So Yuan Yao found Liu Ye, a newly appointed worker, and asked him to promote the tea mulberry industry in the vicinity of Moling and Huangshan respectively, and at the same time cooperate with the reform work of Lusu.

To this end, Yuan Yao also handed Liu Ye a later generation of production technology - mulberry fish pond.

Mulberry fish pond is an efficient artificial ecosystem created to make full use of the land, dig deep fish pond, raise the base field, plant mulberry at the pond base, and raise fish in the pond.

Starting from mulberry planting, through silkworm raising and ending in the production cycle of fish farming, it constitutes a close relationship between mulberry, silkworm and fish, forming a relatively complete resource circulation production system of mulberry planting, mulberry leaf silkworm raising, silkworm cocooning, silkworm sand, silkworm pupa, silk reeling wastewater fish farming, fish manure and other mud fertilizer and mulberry.

In this industrial system, the quality of any production link will also affect other production links.

There is a fishing proverb in later generations that "mulberry mao, silkworm strong, fish fat, pond fertilizer, good foundation, silkworm cocoon", which fully illustrates the connection between the various links in the circular production process of mulberry fish pond.

Sankey Fish Pond is a conceptual industrial circulation chain, there is no technical difficulty, Yuan Yao feels that there should be no problem directly handing it over to Liu Ye, it is really not possible to let the clone do it, and then arrange someone to paint the scoop according to the gourd.

There is nothing to change in the rest of the tea industry, that is, the wild tea trees are domesticated and planted, and the key is that the tea-making technology of tea after picking tea needs to be upgraded, which must be planted after the tea is planted.

After explaining Liu Ye's work, Yuan Yao wanted to go back to Lujiang to return the Taishou seal to Liu Xun, and said that he would return it after crossing the river, and now it has been a month since he crossed the river, and Danyang has all received it, so there is really no reason not to give it.

In addition, the clones in the dock have almost completed all the work, and the ships that should be built have been completed, and Yuan Yao is ready to bring these clones back to Jiangdong, with a total of 1,200 people, and their last job in Lujiang is to build 20 shippers of the Stern class catapult battleship.
