Although Li Su likes to enjoy comfortably, when he really devotes himself to work, he is still very powerful and has extremely efficient work.

The main reason is that he doesn’t have any blind commanding leaders who are a layman who can set a KPI for him.

Liu Bei is a typical fully trusted boss and will not manage Li Su's work at all. He will rest if he wants to do it or not.

This leads to Li Su being completely driven by a sense of accomplishment. As long as he enters the work state, he will never be lazy.

What is there to touch when stumble? If you want to play, you can play with it openly. If you are tired of it, come back to work! Having the opportunity to change the world is a blessing!

Just a few days after arriving at the Dao Road, Li Su brought two thousand guards, thousands of local civilians recruited in winter, and the Tuntian Duwei Guoyuan who came to meet, together along the Lu River, explored more than 100 miles of river surface, and passed two small counties such as Anshang and Mahu on the side of Yueli County, as well as Xindao County newly established this year on the Zhuti County.

As a result of the exploration, there were more than a dozen dangerous shoals with silt accumulation and difficult navigation, and there were three or four reefs and rocks. All of them were marked on the map by the military staff.

If the silt and dangerous shoals can be excavated on the spot, the silt will be dug on site and piled them on the plains of the river beaches on both sides. Then mark them on the map and consider coordinating the farming points nearby in the future. The silt in the river is just dug up to level the fertile fields on both sides of the river.

Because Li Su knew that the mud shallows formed by the river flow were the result of natural erosion, and it was not good if you dig it once. It was because the river flow turned and the flow rate dropped, and when it reached some points, it was easy to accumulate due to the tilt force of the northern hemisphere. It had to be dug every few years to avoid stranding and dangerous shoals, which were easy to sail.

As for the reef, it cannot be handled at once, so I will put it on it first and slowly concentrate my troops to chew it off.

After rectifying the situation, Li Su found that the construction was not difficult and the cost of money was within the acceptable range. He solicited thousands of civilians and soldiers to work, and only needed to raise 10,000 or 20,000 shi of stored grain from the Guanjian of Jianwei County every month, and pay a little iron and tool expenses, and there was not much money.

"Oh, this doesn't seem difficult at all. In a month, even the reefs, it's absolutely no difficulty to rectify the waterways in front of more than 100 miles. If I leave in the first month, you can continue to work. Before the spring plowing, you can work for more than 100 miles to Zhuti County. Why did those predecessors who were officials in Jianwei and Yueli didn't expect to do this? It's really a corpse-positioned meal."

One day in the middle of the twelfth lunar month? After another dangerous shoal was rectified, Li Su stood on the high side of the hillside, giving instructions to the country with emotion.

Pang Xi, the prefect Zhu Ti who followed him to inspect, pretended not to hear it? Anyway, he had just taken office not long ago? He was definitely not talking about him.

Guoyuan, the military field commander, was relatively pragmatic and pointed out some of Li Su's views very pertinently:

"Governor? Don't underestimate this matter. In my opinion, we are doing fast now? It's just because of the glimpse of the silt when cleaning the silt? There was no deep digging. I just dug the silt that floated to the shore. The excavation depth below the water surface will not exceed two feet. This depth cannot exceed a large ship with hundreds of stones at most, and at most it will be sailed. At that time, the large ships will have to unload the cargo pallets and pass by the beach."

Li Su laughed and said, "If it is true as you said, then dig deeper next winter. Anyway, we have time? Can't we do it a year? We'll trade one year later. But I bet that if we dig two feet under the water in the shallows like this, we will definitely be able to navigate the ship in May next year.

The Yangtze River also has a dry and abundant water season. In winter, the ice and snow melt less and rain less in the upper reaches of the river? The water level drops. So we took advantage of the coldest water level in winter to dredge. Now we are digging to the shallowest part of the shallower. The water depth is two feet? In May, it can be at least seven or eight feet deep or even ten feet deep! What big boat can't pass!"

Rivers have water levels gaps between the dry and abundant water periods, which is common sense that later generations think of. But the Han Dynasty obviously didn't pay much attention to these things? Guoyuan had been engaged in military farming water conservancy, and only noticed this problem was reminded by Li Su. Others didn't have this string in their minds.

Therefore, in history, Cao Cao's attack on the Wuhuan was a sudden move? Only Tian Chou needed to guide the way? Only a geography master like Tian Chou, who was familiar with the local situation, knew that "in the autumn of the Liaoxi Corridor, there was no shallow traffic and horses, and there was no deep boat and oar. It was all swamped, and there was only a detour to Lulong Pass."

There are still too few talents who can pay attention to common sense in their minds in their geography.

Guoyuan immediately realized the truth and said in awe: "I was negligent, but I didn't expect the impact of dry water on the waterway. It turned out that the governor asked us to dredge the cold winter, which had a deeper meaning, saving a lot of people's power, money and food."

When digging a waterway, it is necessary to dig two feet deep underwater or one feet deep underwater. For the engineering and technical difficulty of the Han Dynasty, the latter cost far more than five times that of the former, because the construction cost of deep water increases exponentially, and it is easy to drown the civilians, which is very dangerous. It is already a great merit to save people's strength.

After hearing Guo Yuan's support, the officials and officials nearby also had fewer complaints about Li Su's efforts to recruit people's power, and everyone's morale also rose again. After all, it seems that the new surrendered governor is still very sympathetic and cherish people's power.

The minor officials encouraged the people: "Everyone, work hard, dig a little more now, and you can do three or four times less during the busy farming season in summer and autumn. The governor will not treat everyone badly."

...

After solving the route, method and morale issues, new doubts and contradictions will always be gradually exposed as the construction progresses.

Li Su personally inspected and supervised the work and planned on both sides of the Lushui River. Before he knew it, he was busy for about half a month, and it was about to enter the late twelfth lunar month.

As the waterway rectification gradually approaches Zhuti, the depth of the army and civilians' deep into the unmanned land is getting farther and farther. In this way, not only does the waterway need to be dredged, but Guoyuan's supporting military farm planning is also becoming more and more busy.

Because Guoyuan was reminded by Li Su that he noticed the key point of "the slack water in winter is the shallowest and most suitable for dredging", his subsequent work plan will definitely focus on this technical feature to reduce the "total maintenance cost of the entire life cycle of the project."

The military farming sites were set up on both sides of the Lushui River so that the people of the military farming sites would not have to pay taxes to the court. Instead, they would dig out the silt silt in the new year during the slack season every winter, and use this kind of corvee to replace the taxes. This would save the cost of waterway maintenance to the greatest extent. In the future, the court would not need to allocate funds once and for all. Just feed dozens of farmers every dozen miles on both sides of the Lushui River.

As the workload of planning the military farm site was more, Guoyuan felt that it was under great pressure.

Gradually, Guoyuan led a group of minor officials and one night, he discussed with Li Su about the issue of confidence and feasibility.

"Governor, we are unhappy when we say nothing, so we ask the Governor to answer our doubts, otherwise these people in the military farming industry would not be placed in such a deep mountain by us again.

A few days ago, dozens of residents had become refugees and fled back to the north. Even when we found farmers to move the village from Zhuti County, we had white hair to them and gave them fresh silted river fields, they were unwilling to plant them, and they all wanted to return to their hometown. Even if their hometown was less than two hundred miles away, they were unwilling to stay here to farm."

Li Su was in the tent, and he adjusted his hand. He put down the pen ruler when he heard this, realizing that the problem must be solved: "Why did this come to this? Are they afraid that the system of the imperial court to exempt them from taxes and labor service in the future will not be implemented? I am writing this to the General of the Western Expedition. You see, I have written half of it.

I plan to suggest setting up a set of people in the counties and counties under Yizhou, using counties or townships as units, to implement the "rental and mediocre law" to allow taxes, taxes and labor to be replaced by military service. The land where barbarians send troops will be replaced by military service. The roads along the river are rectified, the military farms are transported, and the form of labor service is replaced by river construction, water conservancy, loading and unloading goods and other corvee services. Everyone must believe me, and the benevolence and righteousness of the Western General will definitely approve the implementation."

Guoyuan waved his hand: "It's not that we are afraid that corvee and taxes cannot be replaced by each other. The more we cultivate, the more we are, we are almost at the uninhabited land. These people who have been moved to maintain river workers are afraid that from now on, they will live in deep mountains and valleys isolated from people. Every day, they will either face the mountains behind or the Lushui in front of them, and they will also miss their homesickness.

What's more, the Lushui River has always been considered to be prevalent in the hearts of local people, especially in the beginning of spring every year, in March and April, the miasma can poison all those who cross the river until May. If they are moved to these places, there is no land to go out, and only the Lushui River waterway communication, they are afraid of being trapped here and abandoned by the court."

Li Su realized the key point and immediately refuted: "Why did they have such an idea? Of course, the court would not abandon them. We worked hard to dredge the Lushui channel in order to allow goods to be passed through the South China Sea in the future and a steady stream of business travel. At that time, the villages where they farmed will grow into a dock ferry and become rich.

How could they think that Lushui is a dead river that can only be used in war? This is the main source of the Yangtze River, with a surging river that stretches for thousands of miles and is developed along the river. How likely is it to be waiting for them?"

To be honest, Li Su had noticed this problem before, but he never understood why the Han Dynasty was so resistant to continuing development along the middle and upper reaches of the Lu River. Even locals who were accustomed to tropical climates were resistant.

It was not until Guoyuan's answer came to this point that Li Su realized another crux of the problem:

"What? Governor, although you have a high position and power, you can't talk nonsense with your eyes open... The source of the Yangtze River is well known to be the Minjiang River. Lushui is just a poisonous miasma water coming from the south. Isn't it necessary for the people to be afraid of it?"

Li Su was stunned.

No wonder the Jinsha River has been called "Lu Shui" and "Lu Shui". Although he felt awkward before, why is the only "Minjiang" called "River" from the upstream of Wudao County, and the "Lu Shui" representing the Jinsha River is just "water".

In conjunction with the ancients, they did not know that the Jinsha River was the source of the Yangtze River, and they thought that it was just a poisonous water from the southern barbarians, but they thought that the Minjiang River was the orthodox source of the Yangtze River.

Li Su laughed at himself: "It was me who neglected. Since ancient times, I have been doing things with justice. First of all, I have to dispel the people's doubts about "Lu River is the poisonous water of the Nanman", so that I can talk about governing the people and let them use them for my own use. You must listen to me first, do it well, and I will take the time to write a book "The Examination of the Dajiang Zhengyuan".

Of course, I will never work behind closed doors. If anyone of you is willing, you will ride a horse along the riverside and go up the river. We are down-to-earth and see it is true. The nonsense about the source of the river in "Shangshu. Yao Dian" and "Records of the Grand Historian. Xia Bian" are all put aside first. If you dare to follow me to go a thousand miles and pass Yueli County, you will definitely find that the Lu River will turn north again and come out of the snow-capped mountains.

There are at least thousands of miles of Lushui, and we can't walk it. However, as long as we walk out of Yuezhi County, we can prove that Lushui is definitely longer than the Minjiang River. It is the main source of the Yangtze River. How could it be poisonous? How could there be no dense business trips in the future? I have thought about it, and when I prove this, I will change the name of Lushui to Jinsha River in "The Great River Zhengyuan Catalog". Why is the Minjiang River only called Jiang!"

After all, Li Su was a great scholar of the world and was known for knowing the destiny of heaven.

Guoyuan, Pang Xi saw that he was very confident in his words, refuted the records of the geography knowledge part in "Shangshu". The records of the geography knowledge in "Records of the Grand Historian" were made up. He said so well and he believed it for a moment.

Even if Li Su himself could not do this with the geographical expedition team, he could still do it by sponsoring an expedition team with public funds to go over and take a look, draw a map, and fill the blanks on the map.

Guoyuan thought for a while and ordered his subordinates: "Li Zhonglang is a great wise man in the world and is well-versed in the world. When he said this, we will explain it to the people first, stabilize the hearts of the people and let them continue to build construction, reclaim land and dredge. Let's talk about the others slowly."
