If you want to take it, you must give it to it.

Since Meng Xin and E Shun surrendered, Li Su has already squeezed out a lot of strength from them. It is obviously not an excellent method of controlling the enemy, so at this time, you need to give them blood transfusions and produce some desserts.

Throughout November and twelfth lunar month of 191, the entire Jianning County and the area around the easternmost part of Yongchang County were in full swing in full swing in an atmosphere of "making wealth", rescheduling the army and resuming the people, and focusing on construction.

The military farming Duwei Weishi Road, which has had two years of excellent farming experience in Jiameng and Yudao, was once again transferred by Li Su to the border between Jianning and Yongchang to rectify roads, build terraces, and reclaim hillside tea forests. It was in full swing. As for the subsequent military farming rectification work on the other side of Yudao, it was handed over to the new generation of military farming officials trained by Guoyuan to take over.

Moreover, Li Su was not in vain to call people. The moment Guoyuan arrived in Nanzhong, Li Su had already asked Liu Bei in advance and directly promoted him from Diannong Commander to Diannong Commander.

In name, the commander is only responsible for the military farming affairs of a county at the same time. After being upgraded to the lieutenant, according to the official position of Liu Bei's camp, he can be in charge of the military farming construction affairs of the entire Nanzhong region or the surrendered governor's office. If he is further promoted to the Diannong General, he will be able to be responsible for the military farming affairs of the entire Yizhou.

The southern central area has a warm and humid climate, fertile land, and it is not hard for the people to farm, so the people are rich. On the contrary, because the plants grow rapidly and lushly, there are many wild fruits, birds and animals, the population in Yongchang County is 1.5 million and 600,000, but the land is insufficient, so the per capita ration is very low.

So before Li Sulai presided over the military farming, Yongchang was almost lazy in a state of laziness where "the people had nothing to eat, but they had no work to do, so they just lie down to rest and work less, reducing energy consumption." Therefore, as long as Li Su was willing to teach the barbarian kings to expand production, some of the surplus labor could be built in large quantities.

In just two months, Mengchang and Mengxin brothers witnessed the ever-changing huge changes with their own eyes.

At least several rows of terraced fields were opened on both sides of the mountain roads that were more than 100 miles around Jiandong County, with a total of more than 500,000 acres. They were all repaired with stones, which means that they could store water and plant rice.

In the north, Guoyuan has calculated the cost of developing terraces after two years of experience. It takes about fifteen people a year to build dry fields to produce arable farming land for one person. The paddy fields are twenty-five times because they need to build stones along with water storage.

In other words, the Han system tax collection is calculated based on the per capita of the people who cultivate 100 Chinese mu (30 mu in modern times), and to build 100 Chinese mu of terraced fields, it will cost 15 to 25 people to work for a whole year to open up land.

The terraced fields of 500,000 Chinese mu are enough for 5,000 strong men to cultivate for full amount, and they are all paddy fields for planting rice. Originally, at least 130,000 strong men had to work for a year to open up land, but now they have only been working for two months in winter slack, and the time has been reduced by six times. In theory, the number of people who invested six times is more than 700,000 laborers for land reclamation.

But in fact, the Kunming Heiyi in the entire Yongchang County is only 500,000 to 600,000, accounting for one-third of the population of Yongchang County. There are also 700,000 to 800,000 to 800,000 to 300,000 to 400,000 to 300,000 to 400,000 to 300,000 to 400,000 to 300,000 to 400,000 to 400,000 to 300,000 to 400,000 to 300,000 to 400,000 to 300,000 to 400,000 to 300,000 to 400,000 to 300,000 to 400,000 to 300,

Moreover, the black Yi of Kunming belonged to Mengchang's subordinates, and there were also some small tribes that did not listen to his orders. Mengchang only had more than 300,000 tribes in Yongchang, and more than 100,000 tribes in Qinzang County and other places in Jianning. The total number of Mengchang's subordinates in the two counties was only 500,000.

(Note: When Yongchang County was registered in the Eastern Han Dynasty, the population of Yueli County was different from that of Jianning County and Jingli County. Yongchang Yueli counted all the Yi people in the households, and Jianning only counted the Han people, so there were very few Jianning people, only 130,000 to 140,000, but in fact, there were still 300,000 to 400,000 to 150,600,000 to 150,600,000 to 150,600,000 to 150,600,000 in Yongchang, and all the Yis were counted in it, because when Ailao State surrendered, it was "presented the household registration book", which means that the Barbarian King himself had a established place to count the population.)

Among the 500,000 people in the Mengchang tribe, the elderly and children were not allowed to do labor service to build terraces, so in fact, only about half of the average yield of manpower was used to build so many terraces. This almost doubled efficiency made Li Su shocked at the beginning, and the Meng barbarians who were not aware of the profession were even more moved by Guoyuan's efficiency in getting rich.

For this reason, on the day of the twelfth lunar month, Li Su once asked Guoyuan personally: "Zi Ni, the rice fields in the south are all paddy fields. Why is the difficulty of repairing and manpower consumption far lower than that of the paddy fields in Wudao, and are almost the same as those in Jiameng's dry fields that can only grow radishes and wheat. What are your wonderful methods?"

Guoyuan did not hide his own private matters, and he revealed it proudly: "After garrisoning the land for a long time, he was good at observing the environment and taking advantage of the situation. Although the land in Nanzhong is paddy field, it saves a project than the road and Jiameng, so it is faster."

Li Su: "Oh? I have something to say clearly, what is saved."

Guoyuan: "I also observed the weather for a while after I asked the local old people about it. The local old people said that Yongchang and Jianning all seasons are like spring without winter, so there is no dry autumn and winter freezing. All seasons are full of spring rain, and there is no sunshine for three days.

So I decided to save the irrigation waterways and water trucks of terraced fields. Even the edges of the water storage stones can be slightly worse, and water seeps downwards slightly, but it can satisfy the irrigation throughout the year due to rain. It is precisely because the consideration of irrigation can reduce the project volume by 40%.

Li Su suddenly realized when she heard this, and she felt very moved: the climate in the tropical rainforest is so cool, so there is no need to consider the problem of "irrigation". Just throw a handful of seeds on the ground and wait for it to grow on its own. No wonder those tropical ethnic groups in Southeast Asia can be lazy, but still eat full.

In Yunnan, it seems that the rainfall in just a little less in the twelfth lunar month and the first lunar month, but in the middle of the month and a half, we could have rested and not farmed. The rainfall in the crop growth period is always sufficient for more than ten months.

However, the 500,000 acres of terraced fields were only an additional 5,000 strong men to find farm work, or to feed an additional 20,000 to 30,000 people (one strong men corresponds to a family of five). At first glance, it is not a very unsightly benefit.

In a short period of time, the cultivation of tea trees, pepper and pepper was really allowed to see the effectiveness of Han military farming officials.

There was originally wild tea in Yunnan. In the process of organizing the terraced fields, Guoyuan directly planned the hillsides on both sides of the river valley, which were higher than the planned terraced fields, into tea fields and pepper fields.

The workload of leveling the hillsides required for planting tea trees is much smaller, because as long as you follow the trend of the mountain, each row of tea trees is enough to be at one height, and you don’t have to flatten large flat land like planting rice. A mere tens of thousands of people can burn the wasteland and log the wood to renovate hundreds of thousands of acres of tea gardens in just two months.

The cultivation of pepper and pepper is actually easier after breaking through the technical difficulties - peppers are all vines, and they grow in wild conditions, and very few peppers (peppers) will grow along the stone walls of the rocks.

Later generations who have planted peppers and peppers know that as long as a rack is built to induce the pepper plants to wrap around, artificial planting can be achieved.

Although there are no ready-made pepper racks for sale now, there are many bamboos in the south. You can cut bamboo to build racks casually. Once the local natives learn how to build racks and guide the climbing to initially wrap them up. After teaching these technical details, it is easier to plant on a large scale than to open a tea field - because building a bamboo rack does not require any link to level the land. Even if the ground on the mountain is uneven, cut the bamboo poles on the racks and smooth the tops, so that pepper can be planted anywhere.

Guoyuan brought at least hundreds of farming technicians to teach these illiterate Kunming Heiyi farming skills, and they all learned them in less than two months.

After Mengchang and Mengxin brothers inspected their territory, they slightly asked the Han people's accounting office to do some calculations and found that in just one year, they could achieve reverse export of pepper to the northern region, and they could develop into selling tea within two or three years. At that time, as long as the pepper is mass-produced, they can be exchanged for salt that is not produced locally. There is no need to exchange it with grain or animal skin.

Resources such as animal skins and raw paint can be exchanged for Shu brocade in the north, so that the upper classes among the barbarians can improve their lives. After all, the southwest barbarians do not have the ambition of nomadic peoples, and they do not resist the wariness of breaking through Shu brocade, nor are they afraid of being economically controlled by others. Moreover, the hot and smooth silk in the south is so hot and smooth, even from the perspective of practicality, it is very comfortable to wear.

...

Guoyuan spent hundreds of thousands of acres of terraced fields and more tea forests in two months. While the vine and pepper plantation was planted, there was also a bigger unexpected harvest. Li Su did not expect, that was that Guoyuan actually leveled the mountain road from Qinzang County to Jiandong County.

This will allow future business travelers to travel more easily. Some road sections that were originally used to carry goods with cattle and horses due to rugged bumps can finally be upgraded to cattle and horse pulling carts. In this way, land transportation capacity has been increased by several or even twice as much as the original basis.

Li Sulai knew before that he wanted to open up the new generation of "Shushen Potato Road" commercial route. Only Chengdu to Kunming, Buwei to the Indian Ocean can be transported by water, while most of the two sections between Kunming and Buwei can only be transported by land.

The loss of land freight for these 900 miles will definitely be greater than the sum of the 1,800-mile Yangtze River waterway from Chengdu to Kunming, and the 2,200-mile Nujiang River waterway from Buwei to the Indian Ocean.

Generally speaking, even if there is cargo on land, it is normal that the freight is five times more expensive than driving a ship. A 900-mile land cart can be deducted from 4,500 miles of waterways, and the above two sections of waterways are only 4,000 miles in total.

What's more, Li Su has also seen it in Jianning and Yongchang in the past two months. He knew that although there is no ridge between Kunming and Buwei, he could always find easy hilly roads, but the uneven roads are definitely very serious. Locals carry loads or carry goods.

When Li Su first saw Guoyuan farming on both sides of the valley, even the roads were leveled. He was very surprised at why Guoyuan could complete such a large amount of work so quickly. Although it seemed that when he was only repairing a few narrow terraces, he also built the lowest road in the middle, but after all, he had so much more leveling workload out of thin air.

But Guoyuan quickly told Li Su: "Standing the lowest land is not as hard as high-level terraces, because it can be used to rely on heavy livestock. I think that in addition to domesticating cattle and horses, the southerners can also domesticate giant beasts such as elephants.

I followed the flat faders of the ground with cattle and horses when I was in the north, and then magnified them several times, and let the elephant drag them away. As long as the elephant eats a few trees every day, a giant elephant weighing 20,000 pounds can level the dirt road two miles. After the giant elephant passes, I will manually use a hoe shovel to level it and then pass the car."

Li Su didn't believe it at first, but later he went to the construction site to personally see the elephant grader displayed by Guoyuan, and was stunned: "Zi Ni, you are really a talented person! Since you can even think of using elephants to level the ground, let's make another enlarged one, with several rows of plowshares, so that Kunmingyi can learn to use elephants to cultivate the land. Wouldn't it be nice?"

Guoyuan touched the rubber and thought for a while: "Governor's clever trick, but it's dark under the light. It's not yet the spring plowing season. I haven't thought that elephants can still cultivate the land, but I just thought that terraces can level the road. If we can really use elephants to cultivate the fields, these barbarians will definitely be more in awe of the ingenuity of our Han people."
