In the past month or so, the nine vassal states of the Zhou Dynasty, including the Yan Kingdom, have gradually entered a period of economic prosperity, and the rise of hundreds of industries led by the player power, agriculture, handicrafts, mining, animal husbandry, commerce, transportation, etc., are basically controlled by the player power, and the trade between the adjacent walled cities has also become common and frequent.

Although the player forces have dominated the development of the economy, it is not so simple to rebel and become the king of the kingdom.

From the Son of Heaven of the Zhou royal family, to the monarchs of the nine major vassal states, to the great chiefs of each local walled city, and even the important officials of the walled city, they all have several common surnames - Ji, Jiang, Ying, Zhao, Wu, etc., they respect their common ancestors, marry each other internally, form a family, and rely on blood ties to stabilize the regime. That's how the so-called family world came about.

From the blood general, the Zhou Dynasty ruled the world by a huge NPC family, fathers, sons, brothers, uncles and nephews passed on power, monopolizing the power from the central to the local. It is not so much a state as a large family power - this is the prototype of the formation of the state. It was not until the later Qin Dynasty that this situation was completely reversed, and the state system of county power was fully established, and the local governors were usually no longer relatives of the royal family.

If the player now wants to gain the right to rule a certain walled city, then the direct result is to challenge the entire vassal state, and even the entire Zhou dynasty. A large-scale rebellion in one vassal state will inevitably provoke a fierce reaction from the other vassal states. Jointly carry out the killing.

As long as the players are a little more clear-headed, they won't be playing this kind of bad idea now.

This difficulty is the ultimate challenge at the SSS level, and it is not so easy to complete without a strong enough player force to rise. Most player forces are currently more interested in gaining an economic monopoly than a political monopoly.

The commerce of Zhoushui Walled City has entered an orderly track, and the trade between it and Jicheng, the capital of Yanguo, Bohai Walled City, and Liaoxi Walled City, has gradually entered a prosperous period.

In particular, obtaining a large number of war horses and ordinary horses from the walled cities of western Liao, and forming more bronze cavalry armies of the Zhoushui Alliance, is an important part of the display of military force. Whereas, the bandits of the Lingzhi have some magical effects. Qin Xiaobai did not encourage them to be wiped out, just maintain enough deterrence against them.

Qin Xiaobai stayed in Zhoushui City every day. Or in the fields outside the city, riding horses to inspect the Zhoushui River, etc. He is now at Anxin Zhan Agriculture. and intensify research on agricultural technology.

Agriculture is the weakest link in Zhoushui City. Without food, there would be no way to feed enough slaves, peasants, and soldiers, let alone war. When there is a war, food is consumed as quickly as a fire. After the battle, it is estimated that the various walled cities are also dying.

"Grain seeds, farm tools, cattle ploughing, and water conservancy" are the four major items of agriculture. Choose good food crops. Popularization of agricultural implements, plough tools, irrigation waterwheels, water mills, etc. The popularization of these technologies can significantly increase food production.

Qin Xiaobai asked "money not life" to serve as the technology investment department of Zhoushui University. Lost in money. Concentrate on the work of the shipyard. Asking for money and not life has taken his place, and now the technology investment department is a veritable technology investment.

There is a nice advantage to asking for money and not dying. I only recognize the money, and I don't mind what kind of technology I buy and sell. After he took charge of the technology investment department, he invested in research on various technologies with potential for development, and after the results were obtained, he went to Zhoushui Walled City to find various bigwigs to sell money, and in exchange for money to continue research. As a result, the technology investment department has developed rapidly and has become an important department of Zhoushui University. The more money he earns, the more and more technology accumulation of Zhoushui Academy.

At present, Zhoushui University and University have hundreds of elementary, intermediate and senior NPC teachers, and have established a number of natural disciplines to study basic knowledge; the Institute of Science, with more than three or four hundred full-time researchers; The technology investment department, with thirty or forty players, specializes in finding valuable research projects.

Players in Zhoushui Walled City, who need a technology for any purpose, usually go directly to the Technology Investment Department. Then the technology investment department invests money to make the NPCs of the scientific research institute research and sell them to these players.

This is a virtuous circle, and the NPC researchers of the Research Institute of Science are strong, with solid technology and strong research capabilities. Players can get technology without risk by spending a small amount of money, which is much less risky than spending money on research themselves. And the technology investment department also makes a profit from it. With the money in the university, the research in basic disciplines has gradually deepened.

Take, for example, the "irrigation wheel" of agriculture.

Irrigation water wheel: the shape is similar to a wheel, the diameter of the wheel width is about 20 meters, the small one is more than 10 meters, and it can lift water up to 15-18. There are wooden buckets around the circumference of the waterwheel, and the small buckets below are filled with water, which is rotated by the impact of the water flow, and the water is lifted up, and then poured into the sink to form a stream of water, which flows from the ditch to the farmland.

This waterwheel tool is very suitable for use in the farmland near the Zhoushui River, saving a lot of farmers from diving in the river to irrigate the farmland. Generally, large waterwheels can irrigate 6 or 700 acres of farmland, and small ones can also irrigate 1 or 200 acres. The waterwheel saves labor, effort and money, and can be regarded as the most advanced irrigation tool. Not to mention the farmland in ancient times, many places in modern times also use this thing.

The development of water wheels requires craftsmen who are proficient in wheel hub technology, and it can only be successful after many experiments.

The technology investment department has invested 50,000 yuan to study three types of waterwheels: large, medium and small.

After letting the water-making wheel technology be sold, a player boss in the walled city spent a large amount of copper money to buy the technology of the water-making wheel, specializing in the production of waterwheels. Zhoushui City Walled City immediately added an irrigation waterwheel production industry, and vigorously popularized irrigation waterwheels by the Zhoushui River.

At the same time, the University Physics Department of Zhoushui University has also added three physics research directions: the principle of gears, the principle of levers, and the principle of fluid mechanics, and invested funds for university teachers to study. The NPCs of the Academy of Science went to the university to learn these basics, and then continued to prepare for the research of the second, more advanced irrigation wheels, and even the third generation of irrigation wheels. There is no end to the research of technology, and the development of a primary waterwheel will not stop the further research on the waterwheel. This research will continue until the watermill is phased out and replaced by a better pumping tool.

In Zhoushui City, many players know that Qin Xiaobai monopolizes a large part of the technical research, but they don't have too much dissatisfaction. A very important reason is that the Zhoushui Academy mastered by Qin Xiaobai has brought them too many benefits. In Zhoushui Academy, the latest technology is developed almost every day, and the latest manufacturing industry is born, which is quickly transferred to the players to produce. In this case, most of them were happy to see that Qin Xiaobai was in charge of the Zhoushui Academy alone, rather than being controlled by others, which would bring confusion to this kind of fast research.

At present, there are hundreds of irrigation trucks along the Zhoushui River, pouring water into the farmland on both sides and flowing further along the ditch. In the fields, all kinds of crops are growing well. In the river, many light transport boats transport supplies back and forth, and the whole river is busy and peaceful.

Including the latest irrigation water trucks, these light transport ships were transported to other walled cities farther afield, and sold at high prices in exchange for all kinds of raw materials needed by the Zhoushui walled city.

Qin Xiaobai, the dean of Zhoushui Academy, basically went around the city, outside the city, by the river, and by the lake every day to see the progress in all aspects. He seldom cares about specific matters, and just lets his brothers manage them, but only grasps the direction of the overall progress, thinks about strategic issues, and tries not to make loopholes and mistakes in major policies.

He needs to settle down and lay a solid agricultural foundation for Zhoushui City. It is not enough to rely solely on purchasing grain from other places, but it is necessary to ensure that the grain production and reserves of our own cultivated land are sufficient.

He planned to spend half a month basically popularizing bronze farming tools in the various player tribes in Zhoushui Walled City. In this way, the local food production can be increased by at least 100% to meet the daily consumption of slaves, farmers, and soldiers, and there is a surplus, which gradually fills the player's warehouse and the government warehouse.

During this time, he did not want war or any other major change, and nothing was more important than a calm accumulation of strength. His hope, though beautiful, was utterly impossible.

The fierce competition between the walled cities soon exploded again. This time, the intensity of fierce confrontation is far stronger than that of previous trade disputes. The ships produced by the shipyard of the Mi Cai Qingniu encountered an extremely strong opponent when they walked out of the Zhoushui River system and entered the Bohai Sea.
