Generally speaking, since the defeat of the Zhao family, the land inventory and household registration statistics, and the work of splitting have been carried out very smoothly, and the local powerful forces in Dai County do not dare to openly confront the plateau, and the vast majority of peasant households do not dare to conceal the number of their land properties, and they have truthfully reported their land properties to the officials of the Qing Cha, which has also brought a lot of convenience to the inventory work, so the work of land inventory and household registration statistics and splitting has also progressed very quickly, and the counties and villages near the county town of Dai have quickly completed the statistics. It is expanding like an area like the edge.

Of course, Gao Yuan knew that the local powerful forces would not be willing to suffer their own interests, and would definitely collude in secret to plot a plan to drive him away, but Gao Yuan was not worried, because now he had the support of the army, and there was also a lack of a powerful person among the powerful forces in Daijun, so it was difficult to organize the powerful forces and confront him. And after a long time, the powerful forces are completely dispersed, and it is even more unlikely that they will pose a threat to themselves.

In fact, there are still some hopes that there are a few powerful forces on the plateau who can jump out against him like the Zhao family, because in this way, he will be able to destroy them justifiably, and then confiscate their family property, not only to fight the powerful forces, but also to enrich their own materials and talents.

However, this is just a matter of thinking, and the plateau is also very clear that relying on the way of fighting local tyrants and dividing property is not a long-term solution, and only by cultivating more fields and developing production is the right policy to govern the country. More than 100,000 professional troops were also placed on both sides of the Zhishui River on the plateau, reclaiming wasteland, planting grain, and cultivating more than 500,000 mu of land at once. Houses were built along the river, villages were organized, and canals were dug to divert water for irrigation.

After a period of work, the plateau has also successively arrested four or five thousand people to serve as soldiers, and there are more than 3,000 men, which is a rare batch of free labor, all of which have been sent by the plateau to build houses and dig canals, which has also saved a lot of labor. If this force continues to develop, after two or three years, Daijun will be able to reclaim at least one million mu of land and become completely self-sufficient.

In March, the defenders of Yunzhong, Yanmen, and Shanggu counties surrendered to the Wu'an army, and all the lands of the three counties were included in the control of the plateau.

In fact, after the invasion of the Qin army, although the defenders of Yunzhong and Yanmen surrendered to the Qin army, the Qin State did not send troops to these two counties, so the three counties of Yunzhong, Yanmen, and Shanggu were actually a semi-autonomous state, and the defenders of each county were not many, only three or four thousand people. And Li Mu was very prestigious in these places during his lifetime, and the Wu'an army was originally the remnant of Li Mu, so as soon as the Wu'an army arrived, the defenders of the three counties all surrendered in Kaicheng, expressing their willingness to obey the rule of the plateau.

At this time, the place where the plateau controls zhì is roughly along the south of the ancient Great Wall, in an east-west direction, starting from Huailai in Hebei Province in the east, reaching Yulin in Shanxi Province in the west, spanning the two provinces of Hebei and Shanxi, with a length of about 600 kilometers from east to west, and a maximum width of about 120 kilometers from north to south, but the narrowest is only 60 or 70 kilometers of slender strip-shaped territory. The population is about 1.2 million. It was only then that the plateau really took shape as a nation.

Of course, it is a good thing that the territory is expanding and the population is increasing, but Gao Yuan ordered Sima Shang, Yuan Xuan, Chen Shi and other three people to temporarily garrison them in the same place, and wait for the end of the land survey of Dai County, and then implement the new decree in the other three counties, because as early as the time of the formation of the army, the tasks of each army have been assigned, so each army is also ready to be stationed in the local area for a long time.

And at this time, Gao Yuan also officially sent an envoy to Yan State. Because the plateau is very clear, relative to the Qin State, Zisi is still very weak, relying only on its own development, it is difficult to confront the Qin State, only by forming an alliance with its country, can we gain time and space for development, and now the Yan State is currently the only neighboring country on the plateau in addition to the Qin State, so the Plateau also hopes to form an alliance with the Yan State to jointly fight against the Qin State.

Moreover, Gao Yuan also knew that in another time and space, it was the Tai Xiao Dan of the Yan State who sent Jing Ke to the Qin State to assassinate the Qin Wangzheng, so it seems that there is still a great possibility that he will form an alliance with the Yan State. In addition, Gao Yuan also hoped to open the trade routes of the Yan Kingdom, and use the road to Guò Yan Kingdom to trade with the Qi State.

However, if you want to trade with Qi, Daijun has to come up with competitive products, and Gao Yuan chooses between several items that are out of time and space, glass, porcelain, and paper, and finally chooses paper as his current main commodity.

Because the production process of glass and porcelain is too complicated, with the current level of technology in this era, it is difficult to make more exquisite glass and porcelain items, and even if it is made, the cost will be extremely high, and it can only be sold as high-end goods, and it is difficult to produce and sell in large quantities. And whether it is glass or porcelain, it is not a necessity of life, people can buy it or not. However, if you want to be the main commodity, it must be a popular and popular daily necessities, so glass and porcelain are not suitable choices at present.

In this regard, the advantages of paper are very obvious, because the manufacturing process of paper is relatively simple, and the raw materials are also very cheap, and the manufacturing cost is much lower than that of glass and porcelain. In addition, although paper is not a popular necessity of life, it is much more widely sold than glass and porcelain.

Compared with the main writing of this era, silk has a much greater advantage than wooden and bamboo slips. Because paper is certainly much easier than silk, and after mass production, it will not be more expensive than wooden and bamboo slips, but it is much lighter than wooden slips and bamboo slips, and it is easier to carry and store, and the weight of a wooden book is at least a dozen paper books.

Therefore, as long as it can be made into paper that is easy to write, the amount used is still quite large. In addition, it is possible to develop a peripheral product for papermaking, that is, printing. Books can be printed, then the children of nobles, scholars, and officials from various countries will be potential customers, and the sales will definitely not be a problem.

In the four great inventions of ancient China, only papermaking and printing are complementary to each other, one is indispensable, it can be said that without papermaking, printing is impossible, and printing in turn promotes the progress of papermaking, requiring better quality paper. Therefore, it is the best choice to develop papermaking, make paper the main commodity of Daijun at present, and develop printing technology in the future.

Gao Yuan still remembers that it was said in the history textbooks of middle school that papermaking was invented by Cai Lun, a eunuch in the Eastern Han Dynasty, in fact, according to the research of historians, the earliest papermaking technology should have been in the Qin and Han dynasties, and at the latest it was only produced in the early years of the Western Han Dynasty. On the basis of his predecessors, Cai Lun was to transform papermaking, and his main achievement was to use bark, linen, fish nets and other plants as raw materials, reducing the cost of papermaking, and using some new processes to improve the quality of paper, to create paper that can really be used for writing, and to replace silk, wooden slips, bamboo slips and other things, and finally as a writing plant.

However, there is no doubt that papermaking originated in China, and the origin of papermaking is actually related to silkworm raising and weaving. In ancient China, the working people used high-grade silkworm cocoons to draw silk and weave silk very early, and the remaining evil cocoons and sick cocoons were made of silk cotton by bleaching method. And after each bleaching, there will be some residues left on the rafting mat. When the number of bleaching is too much, the residue on the mat will accumulate into a layer of fiber sheets, which can be used for writing after drying. However, although the cost of the by-product of this bleaching is not high, the quantity is not large, and it is impossible to use it in large quantities, and this product is not called paper, but is called Hewan or square flocculent. The plateau has used this kind of Heyan, and it feels good, and it is much more convenient than bamboo slips and wooden slips.

Although Gao Yuan does not know much about the process of papermaking, he can also know some of the knowledge he has learned in the past and the process of bleaching in this era, and he can also know some in general, first of all, the raw materials are cut and mashed, of course, the more crushed the better; It is then soaked in water and sometimes steamed; After beating hard, these raw materials are beaten into a paste, and the paste is poured on a flat plate, and then pressed, dewatered, dried and other processes, and after all are dried, they can be removed to become paper.

Although the process of papermaking has been continuously improved and matured later, these steps have basically not changed, even in modern society, in mechanized papermaking production, the main production process is still no fundamental difference from the ancient Chinese papermaking method. The development of papermaking technology is mainly reflected in two aspects: in terms of raw materials, Ju Gao Yuan knows, the papermaking raw materials of modern society are mainly wheat stalks, rice stalks and wood, and even bamboo, and different raw materials make different papers. On the other hand, printing and dyeing technology can be used to produce paper of various colors.

Of course, now the plateau does not need colored paper, the focus is on low cost, the process is not too complicated, more large-scale production, and the color of the paper, even does not need to be pure white, gray, yellow, as long as the background color is light, easy to write on the line. As for the raw materials for papermaking, first of all, it is still made of tree bark, linen, fishing nets, or wheat stalks, rice stalks, etc., to try which raw material makes better quality paper. As for whether it can be used for printing, let's wait until the paper is made.

Therefore, Gao Yuan immediately summoned a few craftsmen who were drifting and told them what they thought. And he set them a great prize, and if they could make paper that could be used for writing, they were to be rewarded with a hundred gold medals, and they were also given official positions.

After listening to the idea of the plateau, these craftsmen were also very surprised, I didn't expect the plateau to understand the process of these drifting, and after hearing the heavy rewards promised by the plateau, these craftsmen also had their eyes shining, and immediately said to the plateau that they would do their best to make paper that meets the requirements of the plateau.
