With Zhuge Liang's chance to help get the shuttle ejection structure, Li Su's farming plan to "fully develop the water energy power of Dujiangyan and increase the industrial production capacity in Shu" can be regarded as the last shortcoming that formed a closed loop.

The utilization of water energy involves grinding grain, forging, reeling silk, and textiles. Among them, rice milling is just to liberate female labor force, and is considered a supporting facility and does not generate much additional GDP.

Therefore, the core vision of this plan is about "after the event is completed, the metallurgy and textile industry production capacity in Shu will be increased by two to three times." The implementation process, Li Su, initially calculated with the Zhen family and Zhuge Liang, will be relatively long, and it may take a "five-year plan" to complete.

The main difficulty is the lack of capital needed to "expand reproduction". There are not so many financial tools in this era, and there is no money or enough surplus labor to carry out construction in a crazy way.

A new loom may be able to weave two more wide-width Shu brocades every year without changing manpower investment. However, the cost of the machine itself may also be three or four wide-width Shu brocades or ten old-style narrow-width Shu brocades. In the era of handicraft economy, any machinery is expensive and requires a lot of investment from skilled craftsmen.

In addition, brocades also need to be counted as other raw materials costs, so it is estimated that the cost of each machine will take three years to make a profit. Only in the fourth year can there be "surplus value" to achieve "expanded reproduction". According to Ma Sheng's classic algorithm, it is "the production capacity can be doubled every three years."

This is true for brocade and silk reeling. The recycling cycle of wrought iron and rice milling is almost the same as this speed. The investment of all new production tools itself can be as short as two and a half years to five years.

The fastest return is the mill. The main mill can be almost unattended for twelve hours a day to start milling continuously. Any automated facilities that assist in production must be the longer the start time, the faster the cost is to earn. 996 is faster than the normal working system, and 007 is the fastest.

In contrast, the waterwheel with silk reels is the slowest return because female workers cannot work all night. Even if they work in two shifts, they are not energetic in the second half of the night and are prone to breaking the wire. Moreover, the work of silk reels and calluses has high requirements for lighting, and they have to turn on many oil lamps to start working at night. It is not cost-effective. It is better to waste a few hours of idle time for the waterwheel.

Li Su's planning ability and conscience were not as ill-mouthed as the black-hearted capitalists at the end of the 19th century.

...

After watching the machine, Li Su and Zhuge brothers, and Guan Yu, who was watching the fun, just chatted nonsense and looked forward. The others were full of passion and thought that they were full of soldiers and food, and that the country was rich and strong.

Zhuge Jin was relatively cautious, and after he was happy, he couldn't help asking: "Can this new device be expanded in production like this? After all the people of Shu County use it, can they be promoted to Jianwei and Guanghan?"

Li Su was also a little calmer when asked. After thinking about it, he keenly grasped a bottleneck factor: "Don't be too optimistic. The wide-width crossbow loom can continue to expand production because it does not rely on water conservancy facilities. But the biggest bottleneck of crossbow hoists lies in the national production of beef tendons.

During the Huanling period, cattle were only slaughtered and controlled, and the annual cow tendon was only enough to produce thousands of waist-induced crossbows and slashed crossbows. Our Shu area is located in the south, and there is no large-scale raising of cattle on the grassland, and the people's plowing ox cannot be killed indiscriminately. We can only rely on obtaining supplies from the Yunnan region and other beasts with strong tendons and strong tendons from the south. Or through the Qinling and Shu Road, we can do a lot of beef tendons with Qiang and Hu in the north.

Other wrought iron, silk reels, and rice mills can only be built based on Dujiangyan water conservancy. The upper limit of the future is to set up a large water truck every twenty feet along the coast of the Minjiang River from Du'an to Pi County, including both sides of the straits.

The water flow from Pi County to Chengdu is slowing down and the impact is insufficient. The forty-mile river surface can only be reduced by half, which is equivalent to twenty miles here in Duan. Moreover, there are many irrigation canals separated by Dujiangyan, and several major tributaries can also be used. All of these are included. We calculate that it is equivalent to twice the Minjiang River...

All of them are included, the eighty-mile river bank and the one hundred and sixty-mile tributary bank, and the maximum number of two thousand large water trucks is arranged. Each one is worth 30 people of women, and can continue to work, allowing female workers to take turns, and each car is worth 70 or 80 people of people. Two thousand large water trucks are the labor force of 150,000 peasant women.

According to the current old-style work, the workload of silk reeling and brocade is about one or three, that is, farmers have to produce brocade, one-quarter of the time to reel, and three-quarters of the time to weave brocade. 150,000 bracelets can supply about 400,000 bracelets. In fact, these water trucks have to be divided into several rice mills and forged, and the total production capacity will be lower. To thoroughly digest the production capacity of these water trucks, about 70,000 to 80,000 wide crossbow hoist looms will be built in the future.

Today, Shu County, Jianwei and Guanghan have a total population of 3 million, Shu County accounts for 1.4 million, the middle-aged men are more than 500,000, and women are the same. From this perspective, we can only increase the original production capacity of Shu County, at best, less than twice—

Unless we build more water conservancy in Dujiangyan, the cycle of recovery investment will be even slower. It is a century-long plan and a thousand-year plan. The investment in water conservancy repair may not be able to recover in ten or twenty years, nor may there be enough suitable venues. This is not something you can consider when the war is about to come."

Li Su's words were very good at calculating, which made the Zhuge brothers amazed and thought to himself that Li Boya is worthy of being a good person in the world.

Zhuge Liang's calculations were better than his brother, and he couldn't help but follow Li Su's idea and discuss: "The water conservancy project is too slow to recover the capital. Qin State built Dujiangyan and spent two generations of people to recover the capital, and the subsequent net profit was to make Qin's national strength sufficient to unify the six countries forty or fifty years later.

Zheng Guoqu was also the conspiracy of the Koreans at the beginning. They sent Zhengguo to Qin to repair water conservancy to "destroy its national strength", so that the Qin people had no national strength to destroy Han within a generation. Moreover, Zheng Guoqu did it, which made Han die only twenty years later. The general in the Western Expedition would have to fight the northern expedition for up to five years. It would be better to wait for peace in the world before doing this."

Upon hearing this, Li Su threw a little praise and encouragement to Zhuge Liang.

If it was based on the original trajectory of history, in this troubled Three Kingdoms period, he would have to farm in Shu for more than 30 years before the Northern Expedition, Li Su would consider madly repairing water conservancy and offering map editors. But now it is just a "five-year plan" prepared for the Northern Expedition, and these can only stand aside.

At most, it is particularly urgent to use water energy at the same time, and improve shipping and irrigation conditions. There are benefits in all aspects, so the return cycle may be shortened to less than ten years. If the above three parties do not have major interests, don't think about it.

After understanding this truth, he also reminded Zhuge Liang in a tone of discussion, which was considered to be a saying and deed: "A Liang cannot generalize. If there is a rectification of water conservancy facilities that are best for water energy, irrigation and shipping, it can still be done a little. I looked at Shu County and several counties bordering Jianwei, and Nan'an (Leshan) needs to be rectified.

Nan'an is the intersection of the Minjiang River and Moshui (Dadu River). Now, because the Moshui River is too turbulent, the ship cannot travel. When the ship arrives here, it requires manpower to unload the cargo. It transports the goods to more than ten miles on the ground, and then re-install the ship downstream. This is too expensive. In the future, the goods around Chengdu will be more abundant, and the materials transported along the Minjiang River must pass through Nan'an.

If we build another water conservancy that is slightly smaller than Dujiangyan, block water and control water, and transform the turbulence that hinders shipping into controllable water energy, the three parties will benefit from it at most seven or eight years. At that time, I estimate that there will be a water energy workshop equivalent to 30% of Dujiangyan."

The place Li Su mentioned was the place where Leshan Giant Buddha was built in later generations and needed to rectify shipping stores. Before, Zhao Yun attacked Shu County from the south side, but in Nan'an, he was disgusted by the poor shipping conditions there, so he mentioned it many times with Li Su, and even Li Su remembered it.

Zhuge Liang looked at the map: "But Nan'an is in Jianwei County, and it has been more than 100 miles deep in Jianwei. You are the prefect of Shu County."

Zhuge Jin couldn't get into the conversation at first, but after hearing his younger brother's rebuttal of "upright and unrestrainedness", he couldn't help but laugh: "For Brother Boya, is an official position important? As long as he wants to take care of it, the General of the Western Expedition would let him take care of it everywhere, and he would like to do more."

The future is bright and the process is tortuous.

After counting this plan, the conclusion is that within the "five-year plan", the Jin and iron industry production capacity of Shu County can only be doubled to the current level; after seven or eight years, it will be finally completed and three times the current level. The intermediate process requires the consumption of most of the "surplus value" for "expanding reproduction".

It is impossible to expand greed any more. Due to the limitations of the times, it has reached the ceiling.

However, once this complete body is realized, the benefits are also considerable, and this is easy to calculate.

Li Su transferred out the tax books from previous years and estimated that he could build 500,000 new wide-style Shu County every year out of thin air. Based on six or seven thousand coins per bus, it would be equivalent to more than three billion five-zhu coins.

The country's fiscal revenue per year was only 30 to 4 billion yuan during the reign of Emperor Huan of Han. During the reign of Emperor Ling, the finances collapsed, and the fiscal revenue of the court dropped to 2 billion yuan a year through regular channels, but the money for selling officials and cultivating palaces could be plundered to 2 billion yuan, which was still 4 billion yuan in total.

Li Su is equivalent to directly creating a fiscal revenue equivalent to the Han Dynasty - of course, what Li Su created was only "GDP", which was still very different from fiscal revenue. Among these 3 billion, if the state sells taxes and uses it to enrich the people, only one-third of it can be put into the official pocket.

If the state-owned enterprise is led by chaebols like Li Su and Zhen’s family, and compete for profit with the people, the officials and operators will probably account for more than 2 billion yuan of benefits. There are more than 1 billion yuan for textile workers, silkworm farmers, and mulberry farmers in all aspects, and the wages of ordinary working people are shared.
