Pending down Nanzhong is the biggest war to challenge Li Su's strategic planning capabilities since his debut.

The reason for saying this is not because of how strong the combat power of the barbarian kings in the southwest Yi is, or how invincible the miasma is, but because the butterfly effect of history has been deduced to the deep water area, Li Su doesn't have many foresight to learn from.

Before, from Zhang Ju and Zhang Chun to Liu Yan, there were all references to the history of the Three Kingdoms. Although the characters and time have changed, the geographical situation and offensive route can be referenced.

However, it was difficult to learn from Zhuge Liang's "Seven Captures of Meng Huo" in Pingnan Middle School. Because the records of Zhuge "crossing Lu in May in the middle of the Three Kingdoms" were too brief, and they only wrote about the fate of the Han prefect and hardly mentioned the barbarian chief. The seven caps of Meng Huo in the Romance are obviously unreliable, which led to Li Su having to completely seek truth from facts.

Li Su estimated that there must be a prototype for the seven-capture Meng Huo, but he would never catch a barbarian king so patiently, and he would release it six times. If he really did that, the morale of the Shu Han army in history would definitely collapse first, and he would feel that Zhuge Liang's rewards and punishments were unknown.

Therefore, the Qi Capture is probably to deal with many barbarian kings, and they are divided and disintegrated and won over. In total, they captured seven times. In order to highlight typical characters in order to make artistic needs, Robben merged and absorbed the targets of the Qi Capture and concentrated them on Meng Huo.

Robben has done a lot of artistic treatments like this. For example, some of Zhao Yun's deeds in the Romance are not fabricated, but they are undoubtedly absorbed from the story. Robben likes to combine similar characters with similar characters to highlight typical examples.

After all, only Ma Su's general program, "Surprising the city is the best, and attacking the heart is the best" has a little reference significance.

Pleasure and induce, these are the main themes of Pingnan.

...

After carefully sorting out all the information provided by Guoyuan, Li Su sincerely discussed with Guan Yu and others:

"Chief Yun, according to my opinion, during this southern expedition, I want our direct forces to completely control Jianning County. Jianning prefect Jing Yi believed that he was ordered by Emperor Ling. He had been guarding the place for more than ten years. The road was dangerous and far, and he never surrendered even during the Liu Yan period. He must be despised. Then destroy it and kill it together with some dead and hard barbarians. In addition, replace people. The fastest update is computer::/

Yongchang County uses tutelage as the main focus and war as the auxiliary order. It destroys several particularly hard-working chiefs and Han officials who instigate right and wrong, and wins over the rest for a long time with mutual benefit. As for this mutually beneficial means? It is definitely not for them to unilaterally pay tribute, nor can we win over and buy it with rewards? In the future, we will develop and form a long-term trade model, and everyone has a profitable trade model.

I think the former Yongchang prefect Li Yong clan could completely win over? They were just a prestigious barbarian arbitrator, but now they do not have official positions. We support their descendants to succeed the county magistrate, but we have many Cao officials we sent to manage trade and produce related civil affairs. The Li family will definitely be grateful for our use. As for the barbarian tribes such as Mengchang? They will definitely not be convinced at the beginning. You can hit them at that time."

Guan Yu was not familiar with trade, but was a little surprised, so he confirmed: "Have you told me about this? I don't understand the trade matters, I'm afraid that the Nanman people will not be able to produce in the future and will not be able to provide too much material for our trade. But if you think it's OK, just do it? Let's do it."

Li Su smiled: "It's really not about production now, so in the future we will send agricultural officials to the local government to help them expand their industries and change all the rare treasures of the Southern Barbarians that are currently harvested by wild woodcutting to human farming and mass production? Isn't this the basis of long-term trade?

Since there is no objection to this, let’s talk about the movement of troops. I asked Zini. Before we cultivated the farm and rectified the waterway, even the barbarians in Jianning thought that Lushui was extremely poisonous. It is not suitable to cross the river in spring and autumn. In summer, it is also poisonous during the day, and the water flows rapidly and cannot be navigated.

In previous years, when Zhu Ti wanted to enter Jianning, they all took Zhuti, Hanyang, Cunqiu and Weixian by land. We might as well take advantage of their unpreparedness. On the surface, they still led an army from Zhuti to Cunqiu. Jianning prefect Jing Yi had been familiar with the geography of the road for a long time and would definitely have a large number of troops stationed on the dangerous mountain road between Zhuti and Cunqiu.

Then we ordered a army to go to Lushui, and the Tushui River route was to Muma, south of Wei County, and attacked in surprise. It is best to directly capture Wei County. Even if we can't take it, we will first take Guchang and Dianchi Lake in the enemy's hinterland, and occupy the rich land around the Dianchi Lake Basin. When we sent troops, it should be the autumn harvest in August, and at most it was September when we arrived. The autumn grain had just been in storage, so we occupied the rich farming counties in the Dianchi Lake Basin, so that we could get the enemy because of the grain."

The most dangerous thing about the land mountain road from Zhuti (Zhaotong) to Kunming is to save the sacred mountain (Xuanwei) to Weixian (Qujing), because there is a watershed in the middle.

Warm water flows into Qujing to the south slope, and stored water flows into Xuanwei to the north slope. It is easier to wash the river valley roads. Only when you cross the ridge of the Divide Hill, there is no river erosion, it is steep and difficult to walk, so you can build a checkpoint at the highest point. Although it is not a famous pass, it was not easy in the past.

After hearing this plan, Guan Yu thought for a while, and said in a general way: "Since that's the case, I will make a big fuss and lead five thousand soldiers to attack and lure the enemy from the front. Boya, you will take your third brother and those barbarians and go around the back."

Zhang Fei had subconsciously wanted to refute the merits, but when he heard that the second brother actually gave him the opportunity to attack, he immediately punched him on the cotton. He felt embarrassed:

"Second brother, why are you so embarrassed? Then I'll thank you. Hi, I didn't say anything. Take Dianchi Lake and pick the best spoils to send a few cars to your place. We won't thank you."

Li Su was also a little surprised. Guan Yu looked at their expressions and then smiled proudly: "Since Jing Yi will know that I am the leader of the Southern Expedition, of course, where is my banner? Only then will he believe that he is the main attacker.

Moreover, it was not convenient to fight around the enemy's battle, and the local infantrymen with heavy armor were trapped in the camp and the heavy armor, and they were unhappy to attack. The Banyan Man in Yide led the army was like flying, and he should use his troops to do his best."

Heavy infantry lure the enemy head-on, while light infantry crosses mountains and ridges and attacks in a roundabout way, with a standard combination.

Seeing that their generals did not compete for their merits, Li Su felt more relaxed and was more confident in the follow-up actions.

"Then let's prepare for each of us. After the autumn harvest, we will send troops to the south when the weather is not so hot. In the past two months, you will be responsible for rectifying the soldiers. As for me, I will think about what materials to use to win over the Southern Barbarians for the first trade. Although the tea is good, I am afraid that they can't afford it, so it is not necessary.

In addition, if we want to formally attack Jing Yi without causing other tribes to share the same hatred with Jing Yi, we have to create some excuses. I think of setting up a caravan, bringing some of the most necessary supplies of the South Man, pretending to go to Guanqiu-Weixian business road to sell to Yongchang. As long as Jing Yi cannot withstand the temptation of property and dare to rob our caravan, then we will have the excuse of only beating Jing Yi without offending other barbarian tribes."

Because that is equivalent to Jing Yi blocking Liu Bei from selling cheap goods to people from other counties farther away than Jianning County. Other counties and divisions will also share the same hatred and allow Liu Bei to clean up the thorn that cut off the trade route.

When Guan Yu and Zhang Fei heard this, they felt a little sinister, but they didn't say anything: it was clearly because you wanted to take the initiative to invade others, and they also created excuses for trouble...

But who made Li Su stand on their side?

Li Su asked Guoyuan, who was waiting for the dispatch, casually: "Zi Ni, you have been farming here for more than half a year. You should tell me, for those southern barbarians, what goods are the most popular and necessary, and the best thing is the kind of good thing that 'I won't sell it to him, I just want to pass by his territory and sell it to a third party, and he will be jealous and can't help but want to rob'."

This question is not considered from the "value of the goods", so Guo Yuan thought for a while: "The Southern Barbarians are not as good as those of the Hu people in the north, and even if there is no tea, they will not have much impact. If you really want to say that, I think the "pepper and salt" invented by the governor in recent years is the most valuable and worth grabbing.

There is little Sichuan salt in the southern barbarians. It is difficult to transport the well salt in Jiangyang over the mountains and transport it. The local people cannot bear the high price of salt and are all light food. When I was in the Central Plains, I couldn't figure out how the people in these salt-free places survive so that they would not have swollen necks and become sick.

Later, I asked many natives and found out that they were like cows and horses. They were not clear when drinking water, and directly drank dirty water to replenish salt gas, or burned the remaining ashes with plants and trees, or the toilet soil and white salt on the wet wall bricks to prevent the disease of salt deficiency. It was as hard as cows, horses and animals.”

Li Su was also quite shocked when she heard this, but then she knew that what Guoyuan said was true.

Why do humans have to eat salt while animals do not eat salt specifically and rely on natural diet to supplement minerals?

The main reason is that animals drink natural sewage and have a high mineral content, and cows and elephants will eat soil directly. The natural diet of humans is first of all, "meat does not drink blood" and "vegetarian food does not eat soil". These two points block the intake channels of most animals inorganic salt.

But unexpectedly, the natives of Yunnan and Guizhou in the Han Dynasty would really take in the mineral components of salt like cattle and horses in nature. Who made it far away from the sea and the well salt and the salt lake?

Scrape the white nitrile cream on the toilet wall tiles to eat... Is this a life for people?

"I've decided. At that time, we will send some clever soldiers first and escort a hundred carts of pepper and salt to pretend to sell them to Yongchang County. When passing by Jianning, we won't sell them even if Jing Yi wants to force him to buy them!"

This clearly tempts Jing Yi to rob, so that he can force the people of Yongchang to come over while fighting Jianning to prevent them from joining forces with Jianning.

Considering that people in Yunnan and Guizhou have lacked seasonings since ancient times, they like to be heavy-mouthed, and believe that the temptation of pepper and salt is infinite.

However, Li Su's big hand immediately made Guoyuan a little embarrassed, and Chen Shi, the prefect of Jianwei who had never spoken, was also embarrassed: "Governor, you are not planning to trade well with those barbarians in the future, to sell large amounts of pepper and salt, right? However, the production of well salt in Jiangyang County is already tight.

According to the old man in Shu, the well salt was slightly surplus during the generations of the two emperors of Mingzhang. Later, the population of Shu increased, and the well salt in Jiangyang was to be eaten by four million people and nearly one million people near Jianwei in Nanzhong, which was already in short supply.

If trade is opened on a large scale, the well salt will not be able to hold on. After all, we are not in Xu Yang's place. How much salt is needed in those places around the sea, and the amount of salt produced in each well here is a fixed number and cannot be changed."

Li Su was stunned. He really didn't expect this problem.

Because he remembered that Zigong well salt lasted for a thousand or two years. When Hong Xiuquan broke out in the Qing Dynasty, it blocked the westward entry of Huaiyang materials, and "Sichuan salt to help Chu". Not only could Yunnan, Guizhou and Sichuan eat well salt, but even the two lakes could eat it.

How could such a large salt-rich mine be so difficult to raise five million people?

"Let's discuss this matter again. In a few days, I will go to Jiangyang County with Chang in Jiangyang. What's your Jingyan?"

Guan Yu was going to Jiangyang County, Jianwei County, to train troops, and it was just the way.
