The pacification of Nanzhong is the biggest challenge to Li Su's strategic planning ability since his debut.

The reason why I say this is not because of how strong the combat power of those barbarian kings in the southwest is, or how invincible the miasma is, but because the butterfly effect of history has been deduced to the deep water area, and Li Su doesn't have much foresight to learn from-

Before, starting from Zhang Ju and Zhang Chun, until Liu Yan, there was a war history of "Three Kingdoms" that could be used for reference, although the characters and time had changed, but the geographical situation and offensive route could be used for reference after all.

And Ping Nanzhong, if he wants to learn from Zhuge Liang's "Seven Captures of Meng Huo", it is very difficult. Because the record of Zhuge "crossing Lu in May and going deep into the hair" in the "Chronicles of the Three Kingdoms" is too brief, only the fate of the Han people is too shou, and there is almost no mention of the barbarian chieftains. And the seven captures of Meng Shu in the romance are obviously not credible, which leads to Li Su having to completely seek truth from facts.

Li Su estimated that there must be a prototype of the seven captures of Meng Shu, but he would definitely not catch a barbarian king so patiently catch seven times and release 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 seven captures are estimated to be against many barbarian kings, divided and disintegrated, and they have been captured seven times in total. And Robben, for the sake of artistic needs and highlighting typical characters, merged and absorbed the objects of the seven captures and concentrated them on one Meng Huo-

This kind of artistic treatment of Robben is not less, such as some of Zhao Yun's deeds in the romance, it is not said to be made up, but it is undoubtedly absorbed from Chen, Robben likes to merge similar characters with similar characters to highlight the typical.

After doing the math, only Ma Tan's general program of "attacking the city is the bottom, and attacking the heart is the top" still has a little reference significance.

Appeasement, seduction, this is the main theme of Pingnan.

……

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

"Yun Chang, in my opinion, this southern expedition, I want our descendants to completely control Jianning County. Jianning guarded Jing Yi because he was ordered by Emperor Ling, and he had been guarding the place for more than ten years, and the roads were far away and he had never surrendered even during the Liu Yan period? Will you despise us? Then destroy it, and kill it along with some die-hard brutes? Another substitution.

And for Yongchang County, it is mainly used to Fu and supplemented by war? Destroy a few particularly die-hard Hao chieftains and Han officials who instigate right and wrong, and win over the rest for a long time with mutual benefit. As for this mutually beneficial means? Surely it can't be a unilateral tribute, nor can it be that we buy it with a reward? In the future, it is necessary to develop a long-term trade model that is profitable for everyone.

I think the former Yongchang Taishou Li Hao clan can be completely wooed? They are only a prestigious barbarian arbiter, but now they have no formal official position, and we support their children and grandchildren to succeed them to the post of county guard, but we have more Cao officials we sent to manage civil affairs related to trade and production, and the Li family will definitely be grateful to Dade for our use. As for Meng Wei and other barbarians? Surely you won't be convinced at first? When the time comes, you can knock it out. ”

Guan Yu was not familiar with trade, but he was a little surprised, so he confirmed: "Did you tell the eldest brother about this?" We don't understand the matter of trade, so we are afraid that in the future, Nanban will not be able to produce and will not be able to supply too many materials for us to trade. But Boya, do you think it's okay? Let's do the knife thing. ”

Li Su smiled: "It's true that there is no production now, so in the future, we will send agricultural officials to the local government?" Help them expand their industry and change all the treasures of the Nanban that are currently harvested by wild wood into manual cultivation and mass production? Isn't that the basis for long-term trade?

Since there is no objection to this, let's talk about the use of troops. Did I ask Zini? Before we tuntian and clean up the waterway? Even the local barbarians in Jianning think that Lushui is highly poisonous? It is not suitable to cross the river in spring and autumn, and it is poisonous during the day in summer, and the water is turbulent and unnavigable.

In previous years, when Zhu Ti wanted to enter Jianning, he would take the land route of Zhu Ti, Hanyang, Cunqi, and Weixian, so we might as well take advantage of their unpreparedness and still take an army from Zhu Ti to Cunqi to the south. Jianning is too guarded by Jing Yi to know the geography of the road for a long time, and will definitely station a large number of troops at the dangerous points of the mountain road between Zhuti and Cunqi.

Then we ordered a detachment of troops to take the Lushui and Tushui waterways to go around to Mumahuan south of Wei County and then attack by surprise. It is best to be able to directly take the county of Zhiwei County, even if you can't take it, first take Guchang and Dianchi Lake in the hinterland of the enemy, and occupy the rich land around the Dianchi Basin. When we sent our troops, it should be the autumn harvest in August, and when we arrived, it would be September at most, and the autumn grain had just been put into storage, and the rich farming counties in the Dianchi Basin were occupied, so we could lose the grain to the enemy. ”

The land mountain road from Zhuti (Zhaotong) to Kunming, the most dangerous is between Cunqi (Xuanwei) and Weixian (Qujing), because there is a watershed concave waist mountain in the middle.

The warm water flows into Qujing to the south slope, and the stored water flows to the north slope to Xuanwei, and the river valley scouring road is easier to walk. Only over the watershed ridge, where there is no river to wash and level, is steep and difficult to walk, and a checkpoint is built at the highest point. Although it is not a famous Xiongguan, it was not easy in the past.

Guan Yu listened to this plan, thought about it for a while, and actually said very generally: "In this case, I made a big show and led 5,000 troops to attack and lure the enemy in Cunqi frontally. Boya, you take the third brother and those brute soldiers, and go around the back. ”

Zhang Fei originally subconsciously wanted to refute and steal the credit, but when he heard that the second brother actually gave him the opportunity to attack the main attack, he suddenly felt embarrassed as if he had punched cotton:

"II...... Second brother, how embarrassing is this, then I will thank you, hey, I didn't say it, take Dianchi Lake, pick the best loot and send a few cars to you, let's not thank you. ”

Li Su was also a little surprised, Guan Yu looked at their expressions, and then stroked his hair and smiled proudly: "Since Jing Yi will know that I am the main general of the Southern Expedition at that time, of course, it is where my banner is, and he will believe that it is the main attack."

Moreover, it is also inconvenient to go around the battle behind enemy lines, trapping camps and heavily armored Qianwei local infantry, and it is not fast to rush. The board of the winged virtue belt is barbaric, but the march is like flying, and the soldiers are used to the best of their ability. ”

The heavy infantry lures the enemy head-on, and the light infantry sneaks up the mountains and mountains.

Li Su saw that the cooperation between the generals did not take credit, and he also felt more relaxed, and he was more confident in the follow-up.

"Then we will prepare separately, and after the autumn harvest, when the weather is not so hot, we will send troops south. In the past two months, you will be responsible for rectifying the soldiers, and I'll think about what materials to use for the first trade to win over the Nanban - although Shu brocade and tea are good, I am afraid that they will not be able to afford it, and it is not necessary.

In addition, if we want to officially crusade against Jing Yi without causing other tribes to share the same hatred with Jing Yi, we have to create some excuses. I want to get a caravan at that time, bring some of the most necessary and in-demand materials in Nanban, and pretend to go to Yongchang to sell them on the Cunqi-Wei County trade road. As long as Jing Yi can't withstand the temptation of wealth and dares to rob our caravan, then we have an excuse to only fight Jing Yi and not offend other barbarians. ”

Because that would be tantamount to Jing Yi blocking Liu Bei from selling cheap and good goods to people in other counties farther away than Jianning County, and the other counties and departments would also join the enemy and allow Liu Bei to clean up this thorn in the thorn that cut off the trade route.

When Guan Yu and Zhang Fei heard this, they all felt a little sinister, but they didn't say anything: It's obvious that you want to take the initiative to invade others, and you also create an excuse for incidents......

But who let Li Su be on their side?

Li Su casually asked Guo Yuan, who was waiting for the dispatch next to him: "Zini, you have been here in Tuntian for more than half a year, but you can tell me that for those Nanban, what goods to transport used to be the most popular and necessary, and the best thing is the kind of good things that 'I don't sell to him, but just want to pass by his territory and sell it to a third party, and he will be red and can't help but want to rob it'." ”

This question is not considered from the "value of goods", so Guo Yuan thought for a while: "The southern barbarians are not as meat-eating as the northern Hu people, even if there is no tea, it will not have much impact." If you really want to say that it is necessary, I think that the 'salt and pepper' condiment invented by the governor in recent years is the most valuable and worth grabbing.

There is little Sichuan salt in the land of Nanban, and it was difficult to transport the local well salt from Jiangyang over the mountains in the past, and the local people could not bear the high price of salt and were all light food. When I was in the Central Plains, I couldn't figure out how the people in these saltless lands could survive so that their necks would not become swollen and sick.

Later, I asked many local people, and I learned that they were like cattle and horses, relying on drinking water that was not clear, directly drinking dirty water to replenish salt gas, or burning the remaining ashes with grass and trees, or white nitrate on toilet soil and damp wall tiles, to prevent the disease of salt deficiency, which was as hard as cattle, horses, birds and animals. ”

Li Su was also quite shocked when he heard this, but then he knew that what Guo Yuan said was true.

Why do humans have to eat salt while animals can eat minerals from their natural diets instead of eating salt?

The main reason is that animals drink natural sewage, which has a relatively high mineral content, and cattle and elephants will eat soil directly. The natural diet of human beings is first of all "meat does not drink blood" and "vegetarian food does not eat soil", which blocks the intake channels of most poultry and animal inorganic salts.

But I didn't expect that the natives of Yungui in the Han Dynasty would really ingest mineral components instead of salt just like cattle and horses in nature. Who made this place far from the sea, from the well salt, from the salt lake?

Scrape the white nitrate frost knotted on the wall tiles of the toilet to eat...... Is this the life of man?

"It's decided, when the time comes, let's send some clever soldiers first, escort a hundred and ten carts of pepper and salt to pretend to go to Yongchang County to sell, even if Jing Yi wants to buy it when passing by Jianning, we won't sell it!"

This is to clearly tempt Jing Yi to rob, so that when Jianning is attacked, the people of Yongchang will be forced over to prevent them from joining forces with Jianning.

Considering that people in Yunnan and Guizhou have been short of condiments since ancient times, they like to eat heavily, and I believe that the temptation of pepper and salt is infinite.

However, Li Su's big hand waved a little embarrassed, and it also made Qianwei Taishou Chen Shi, who had never spoken, also very embarrassed: "Dudu, you don't plan to make friends with those barbarians in the future, the first step is to sell a lot of salt and pepper, right?" However, the output of well salt in Jiangyang County is already tight.

Listening to the old legends of Shudi, the well salt was also slightly surplus in the generations of the second emperor of Mingzhang. Later, the population of Shu became more and more, and the salt in Jiangyangjing was already stretched thin to feed four million people and nearly one million people near Qianwei in Nanzhong.

If the trade is opened on a large scale, the well salt will not be able to hold on. After all, we are not a place of Xu Yang, and the amount of salt and salt that is needed in those places that rely on the sea is a fixed number for each well here, and it cannot be changed. ”

Li Su was stunned, he really didn't expect this question.

Because he remembers that Zigong well salt has been held for one or two thousand years, and when Hong Xiuquan broke out in the Qing Dynasty, it blocked the westward advance of Huaiyang materials, and there was also "Sichuan Salt Jichu", not only Yunnan, Guichuan and Sichuan can eat Shangjing salt, but even the two lakes can eat.

How is it possible for such a large salt-rich mine to feed five million people?

"Let's discuss this matter again, in a few days, I will go to Jiangyang County with Yun Chang to see how your well salt is done."

Guan Yu was going to Qianwei County to train troops in Jiangyang County, and he happened to be on the way.
