On paper, I finally feel shallow, and I never know that I have to do it.

If you haven't done some things yourself, you really don't know what strange difficulties will suddenly pop up at the implementation level.

For example, if Li Su were to sit in the yamen of Chengdu and imagine behind closed doors the reason for "the slow progress of the development of shipping in the Jinsha River basin from the late Han Dynasty to the Tang and Song dynasties and the Han civilization", he would probably only think that there were constraints in terms of technical and commercial interests.

Even if he wants to break his head, he won't feel that "the Han people think that the Jinsha River is just an insignificant Nanban poisonous water, and there is no value for in-depth exploration" can also be one of the important reasons.

Because before coming, the reason why Li Su was full of confidence in his plan and dared to pack the ticket in front of Liu Bei was because he knew a little bit of relevant history:

Later, in the Ming and Qing dynasties, with the development of the cause of reclaiming the land in the southwest, the shipping in the middle and upper reaches of the Yangtze River, after a little rectification, could have been unimpeded to reach Laojuntan in Qiaojia County, Zhaotong, Yunnan. The section below Laojun Beach can be solved without any technical difficulty, and the technical equipment and mobilization capacity of the feudal natural economy can be solved.

What the people of the Ming Dynasty can do, Li Su will definitely be able to do it with a little bit of technology.

As for the navigation from Zhaotong Laojuntan to the upper reaches, Li Su never thought about it, because he had read the history of the Anti-Japanese War and knew that even in the 30s of the 20th century, modern engineering technology could not overcome this kind of project.

On the eve of the Anti-Japanese War, the troops of the positive side passed through Laojun Beach on the Long March, but they could not cross the Jinsha River here. As for the troops of the local warlords in the southwest, during the Anti-Japanese War, they originally wanted to develop shipping above Laojuntan to meet the US aid materials brought in from the Yunnan-Burma Highway and realize the water transportation from Yunnan to Sichuan, but they also failed.

Even in the era when such an awesome project as the Yunnan-Burma Highway could be built, Laojuntan shipping could not pass, and it was better to take the 100,000 mountains of Guizhou on the east line and "24 turns" to Chongqing by road transportation.

Li Su didn't have a map editor, so he wouldn't waste his energy.

However, after personally going to the front line and conducting in-depth research among the masses, Li Su is also more confident in his plan: since he knows that the crux of the problem lies in people's hearts and not in technology, it will be easy to solve.

After half a month, Li Su summed up a few experiences in his heart: "It turns out that people from the Tang and Song dynasties are not skilled enough, but they have no motivation to come." The ancients' desire to explore geography was so low, and they didn't have the desire to conquer the outside world at all.

It is no wonder that during the Ming Dynasty, Xu Xiake traveled all over the north and south of the Yangtze River to verify that 'the Min River is not the source of the Yangtze River', but Xu Xiake could not verify how far the source of the Yangtze River is.

It is also basically starting from Xu Xiake that later generations attach importance to the direct development of Southwest Yi - because in the eyes of the Han civilization, the civilizations in the Yangtze River basin are all part of China, and the upper reaches of the Yangtze River are the main source, how can they be regarded as unworthy of conquering? ”

Ignoring geographical development and lacking the spirit of exploration are harmful to others. Since Li Su is here, of course, he must take advantage of his claim to know the destiny of heaven and write foreign exploration and adventure into the cultural spirit.

At this moment, Li Su was thinking about more than just developing Yunnan's native products and agate jadeite, which was a major national spiritual issue.

……

It is a pity that because Li Su himself is thin and weak, although he has the intention to personally stabilize the morale of the army and persist in exploring, his inspection road only went more than 100 miles south of Tanglang County, and he had to turn back.

That place is roughly equivalent to the Qiaojia and Huize counties in Zhaotong in later generations, because after Qiaojia Laojun Beach, you can't take a boat upstream.

And after crossing the southern boundary of Tanglang, the two banks of the Yangtze River belong to Yuewang County and Jianning County respectively, and a hundred miles upstream, the south bank enters Yongchang County from Jianning County.

Liu Bei's current sphere of influence only controls the Zhuti County divided from Qianwei County, so it is very dangerous after leaving the Zhuti realm, and they are all enemy-occupied areas that do not obey the king.

However, Li Su still sent a small expedition team to let them continue to travel by land to make geographical discoveries, and promised that everyone who came back alive would be upgraded to a higher level, and before leaving, he would give his family an additional 30 acres of Yongye field along the Lushui coast as a settlement fee.

There must be brave men under the heavy reward, and there is really a team of dozens of people, under the leadership of a tun commander, with enough dry food and herbs to continue to move forward and draw all the way. Li Su asked them to go at least five hundred miles along the river to the no-man's land—

It doesn't need much, because as long as you walk another 500 miles, then the length of the Lushui that has been discovered is already longer than the Minjiang River, which can prove that this is the positive source.

At the same time, Li Su knew that if he walked two or three hundred miles ahead, it would be about the junction of Yuewang County and Yongchang County, that is, the Panzhihua area in later generations. After walking 300 miles, you will go out of the border of Yongchang County and enter the area that has not been ruled by Han civilization at all, which is roughly equivalent to Lijiang in Yunnan in later generations.

Moreover, before arriving in Lijiang, the Yangtze River will turn north, which is enough to prove that Lushui is not from the poisonous water of the Southern Barbarians, but from the orthodoxy of the Kunlun Snow Mountains in the west.

Adding these materials to "Yangtze River Zhengyuan Examination" is enough to completely stabilize the hearts of developers.

Li Su made an appointment with the expedition team for 15 days, and he himself would stay in Zhuti County to continue to inspect and supervise the work, and he would not even return to Chengdu on the eve of the Chinese New Year. If the expedition does not return after fifteen days, then report to Guoyuan.

The expedition team was lucky, except for five or six people who died of poisonous insect and snake bites on the way, and were eaten by the barbarians of Daliang Mountain, the others came back alive, and also brought Li Suyao's hydrological and geographical information.

Li Su gave generous condolences to the victims, and in the future, he will be included in the preface of "Dae Zhengyuan Examination" and listed as "those who have contributed to this book". The reward for the promotion of the living.

……

When the expedition team returned, most of the waterway improvement work on the Guoyuan side was almost completed.

Seeing that Li Dudu's prophecy and command were fulfilled one by one, Guoyuan was also full of admiration, and couldn't help but praise it:

"It is all up to the governor to override the opinions of the people, and not to be moved by the rumors of the wavering. Our army was able to go to Lushui, which was regarded as a forbidden place by the barbarians, and went directly to Tanglang County, and then transferred to Tushui, and in the future, it went straight to Muma and Guchang, and surrendered to Jianning Man, wouldn't it be like divine help and divine soldiers descending from heaven! ”

Guo Yuan's remarks are definitely not bragging, because Li Su's rectification of shipping is not only of commercial development significance, but also of military surprise attack significance.

Since ancient times, people went to Jianning County, and they all went from the Yandao into Yangguanshui, to Zhuti County, and then Zhuti County to the south is the land route, and it is necessary to pass through Cunqi (Xuanwei) and Weixian (Qujing) to reach the Kunming Basin around Dianchi Lake.

It is precisely because this road was very important in the original history that Liu Bei's residence in the original history was chosen in Wei County, Jianning County. When Zhuge Liang crusaded against Meng Shu, Meng Shu had to guard the dangerous mountain passes, and he also used Wei County as the gateway to southern Yunnan to guard the heavy troops.

After Li Su opened up the Lushui shipping, in the future, he would fight a war, and he would directly enter the Kunming Basin without passing through Wei County, and the surprise attack effect would definitely be better than Deng Ai smuggling into Yinping and blocking Jiang Wei in the Jiange Road.

Of course, Guoyuan still doesn't know where to go around Tushui, because no one has walked this road since ancient times. But this did not prevent him from admiring Li Dudu's great courage.

But now everything still has to be kept secret, anyway, there are no barbarians to stop the river here, and I don't know what they are doing, and they won't associate it with the military arteries hundreds of miles away, and the barbarians don't have this IQ.

As long as the Han army officials who repaired the river were tight-lipped about their motives and kept it secret until the autumn harvest and used the troops, it would not be a problem, anyway, Guoyuan himself knew that it had to be kept secret.

Li Su's praise of Guoyuan is also very modest:

"Don't tout too much, we're just trying to benefit the people. It is better to teach people to fish than to teach them to fish, and the key to making the southwest Yi Sinicized is to let them make a living, learn to produce the needs of the Han people, and communicate whether they have enough food and clothing.

Once they have to do business with the Han people to live well, the ghosts will rebel and stand on their own, which can be supplemented by official conferring and indoctrination in the future. This year we are just doing the first step, I should almost go, you can do the things here, there are uncertain messengers to Chengdu. ”

"Subordinates obey." Guo Yuan dutifully agreed, and then sent a boat down the river to send Li Su back.

On the way back, Li Su did not forget to inspect the work and gave guidance from time to time.

Not to mention, Guo Yuan's work experience accumulated last year was just moved to Lushui, and he was really uncomfortable, and there were several jokes at the beginning. In the past few days on the return trip, Guoyuan has often reviewed with Li Su.

For example, when they first returned to Tuntian, a newly established county town at the intersection of Tushui and Lushui, the people complained bitterly and demanded that Guoyuan be exempted from the rabbit tax, saying that the method he taught did not work.

"What's going on? Go find out. "Li Su is very Qingtian and personally takes some time to ask about these disputes.

So some representatives of the tunmin came to complain: "Governor, the governor let us release rabbits to breed, and set traps to catch and make dry rabbits in the coldest time of winter." For every 10 rabbits we were given, 50 rabbit jerky would be levied as a tax to subsidize military rations after the winter.

But we put the traps, and the rabbits that were raised out of the range could not be caught at all, or they caught very little, and they were not enough to pay taxes, and we didn't have a bite of meat left behind! ”

Li Su hurriedly went over to investigate in depth, only to find the crux of the problem, and couldn't help but laugh dumbly: "Guoyuan! Are you a rubber pillar drummer, the tricks I used when I was in Daba Mountain, can you directly use them to Daliang Mountain? It's not the same thing at all, okay!

Daba Mountain is close to the Qinling Mountains, and it is considered northern, and it will be covered by heavy snow in winter! The rabbits released in the wild can't find anything to eat, so they will be caught by the little radish bait of the tun people. This Daliang Mountain is at least more than a thousand miles south of Daba Mountain, how hot is the weather?

In winter, there is no snow at all to cover the mountains, and of course the rabbits you let out will not be caught! You don't even know if it snows in the winter here, so you dare to go wild and raise rabbits? Forget it, the account of the rabbit's loss is recorded on the head of the government, and it is listed separately, and the people cannot be asked to bear it. If you have a lot of bushes and grass on the hillside here, you should raise goats, because sheep are not as good as rabbits. ”

Guoyuan was quite ashamed: "I also came in a hurry, and I didn't have time to investigate." ”

Li Su: "It's good to pay attention next time, don't make the same mistake a second time, write down the lessons, and communicate with other colleagues and subordinates to learn whether they have or not." This time is also pressed for time, and I don't blame you. ”

Li Su knows very well that he should grasp the big and let go of the small, and for setting unreasonable KPIs, he must give his subordinates a reduction or exemption at the end of the year, so that the morale of everyone will be high.

Although he gave up the income of rabbits and changed to goats, Li Su found many problems during the run-in period during his return trip in the following days.

For example, when Li Su walked to Xindao County and was about to return to Yandao and leave the mountainous area, a group of people came to complain, saying that the breeding sheep distributed by the Tuntian official had been harmed by wild beasts, and they were all fenced and repaired sheepfolds in accordance with the construction specifications required by the Tuntian official, but they were still broken through by the beasts, killed a few sheep, and the rest scattered a lot, asking the government to give up retroactive loss tax reduction.

This little should not have been handled by Li Su, but it is still necessary to inspect once or twice once in a while to assess systemic risks.

Li Su set aside half a day to personally inspect the tuntian site. As a result, when I arrived at the place, I saw that the sheepfold was very strong, and it was all tied with bamboo.

Qiongzhu is a kind of bamboo that is a specialty of Nanzhong, because the plants of the tropical rainforest are relatively tall, the distance between the best Qiongzhu bamboo and the bamboo can be more than one zhang, very solid, and the cane can be made to do not see a bamboo knot on the whole cane, so "Qiongzhu cane" is one of the foreign trade fist products of Southwest Yi since ancient times.

Even the fence made of thick bamboo was actually broken through by the beasts, and it seems that the villagers of Tuntian should not be blamed for poor management.

But Guoyuan had just made a fool of himself in front of the governor two days ago, and he was still a little unwilling, and wanted to isolate a few people and torture him: "Who knows if there was a loophole here when you repaired it, or if you cut the fence with a sharp blade, let the wolves kill the sheep, and want to make profits in the chaos to deceive the fat sheep of the government!" ”

In the end, a resident who was familiar with the local geography came out to complain and complain: "Captain, we can't think of this kind of crooked brain, but the damage to this sheepfold is by no means cut by a wolf or a sharp blade." If it is injured by a sharp blade, there should be a lot of fragments of bamboo fences scattered, and the fractures will not be so staggered.

Now there are not even fragments left, I'm afraid it won't be harmed by the iron-eating beasts that are special to this place! Iron-eating beasts can even eat bamboo, and in the cold winter without bamboo season, there are iron-eating beasts that will go down the mountain to eat the fence first, and then break the fence to eat the sheep. If you want me to say, your method of persuading the people to raise sheep is not right in the first place.

Either organize the people to hunt and kill the iron-eating beasts, or use the tender bamboo to surround another circle, and put one or two sheep and winter bamboo shoots that feed the monsters in it, so that when the beasts go down the mountain, most of them will eat the tender bamboo circles and lambs and winter bamboo shoots, and let go of the others when they are full. It's that you don't know how to raise sheep in this southern land, so what do you have to do with us! ”

It can be seen that the person who spoke was also a local native, so he didn't have much respect for the officials, and he dared to choke on Guoyuan, a layman, like this, maybe he was prepared to "offend the government and run away again to be a savage in the mountains".

However, Li Su listened to it next to him, and realized very fairly that maybe Guoyuan had made the mistake of not understanding the local situation again.

Li Su touched his beard and thought for a while, and asked, "The beast you are talking about, but it is black and white?" That is, the body is white, and the limbs and ears are black? ”

When Qu Tunmin heard that the governor was in charge of him, his eyes immediately lit up: "The governor is really well-informed, and he even knows the appearance of an iron-eating beast that is rare among our locals, and it is true." If the governor wants, we will be able to catch it by the blood of the sheep if we have the opportunity in the future. ”

Li Su nodded: "That's right, they shouldn't be lying." Guoyuan immediately asked the nearby sheep farmers to rectify according to what they said. Sun Tzu said: Those who can win but do not win will win, and we must use professional people to do professional things. How to implement it in the local tuntian, we must first listen to the opinions of the locals. I'm leaving, you can think about it later. ”

Guo Yuan was quite ashamed: "It was my negligence, thank you for your advice." ”

Li Su also knew that this was a small problem in the development process, and he did not blame him, and two days later, he returned to Chengdu from Yandao with the jade agate, a specialty of Nanban, given by Wudou Pang Xi, and the two beasts sent by Guoyuan as evidence.

After the autumn harvest, when the southern expedition to the South Barbarians, let's accept the results again.
