Sijia slaughtered and destroyed the Ming army's walled city in the mine, which Zhu Gaoxu really did not expect. He didn't think it was likely, at least.

Zhu Gaoxu had read all the old files of the capital and read all the records about the Luchuan region, so he made such a judgment. However, he still underestimated Sijia's arrogance, or overestimated Toast's foresight.

…… On that territory, the most arrogant and uncontrollable toast must be Sijia toast!

During the Yuan Dynasty, the territory of Sijia was very large, and it was called Luchuan. The Yuan army couldn't do anything about them, and the Luchuan Kingdom continued to grow, forcing the Yuan court to keep retreating.

It was not until the Ming Dynasty entered Yunnan on a large scale that the situation changed. The Ming Dynasty Imperial Court, Yunnan Sansi and Mufu have been operating the Luchuan area for more than ten years, using the means of divide and rule to "analyze the Luchuan land"; It was divided into large and small toasts, which gradually weakened the strength of Sijia. During the implementation of this strategy, Mu Ying personally led a large army to conquer Sijia several times, and suppressed the resistance of Sijia Tusi by force, which completed the division of the original Luchuan Kingdom.

In recent years, Sijia began to annex some villages, which immediately attracted the attention of Yunnan Dusi, who was far away in Kunming City; It's just that this toast is too tricky, and it has plagued the Yunnan government for a long time, and it is very valued by all parties in the Ming Dynasty.

But now, Sijia is still in the time of recovery, and it is also the time when it is the weakest.

The toast that can give the Yuan Dynasty a headache and survive until now should be somewhat far-sighted. Therefore, Zhu Gaoxu made a judgment that the most correct way to think about the family at this time was to Taoguang and cultivate obscurity, and he should try his best to agree to some not too excessive requirements of the Ming Dynasty; Expand gradually and slowly accumulate strength. Then wait for the opportunity.

…… However, Zhu Gaoxu's self-righteous judgment was obviously slapped in the face by Sijia, and Sixingfa directly bulldozed the walled pit without saying a word!

So Zhu Gaoxu completely changed his mind and re-examined and upgraded his idea of dealing with this matter.

He has gradually mastered the military and political affairs of Yunnan, and in the face of the most difficult thorn in Yunnan, he decided to take advantage of his illness and kill him! Otherwise, when Sijia is stronger, it will definitely be even hotter to pay attention to it.

Since Sixingfa didn't want to do business, Zhu Gaoxu decided to get his face back; By the way, it also solved a problem for the Ming court. After all, his current identity is the grandson of Taizu, and sometimes he subconsciously has some sense of responsibility.

Zhu Gaoxu decided to raid Meng Yangsi first, and in case it didn't go well, he also thought of a way out...... Write to the emperor, continue to transfer troops and food, and do this battlefield to the end!

Since the "Battle of Jingyan", Zhu Gaoxu thought that his father Zhu Di was a very far-sighted person, so he believed that Zhu Di would agree with his views on Meng Yangsi.

…… Five thousand elite soldiers were selected among the three guards, Zhu Gaoxu took Wei Da and Liu Ying as generals, and Zhao Ping as the general of the personal guard; Wang Bin and Chen Dazhui were left behind, leading the guards of the Han Palace.

He first summoned Wang Bin and Chen Dazhui to meet in the study, and quietly told them that Chen Gang, the military general in the guard army, and Yu Meiqing, were treacherous spies, so that they knew in their hearts, but they couldn't startle the snake.

Then Zhu Gaoxu met with Hou Hai alone, the warden of the Han Palace, and reminded Hou Hai that the right chief Shi Li Mo was a traitor. During the expedition, Hou Hai was asked to pay attention to what Li Mo was doing, especially the personnel actions of the Changshi Mansion.

The eunuch in charge of the affairs instead told Zhu Gaoxu to be more at ease, Wang Gui was the old man of the former county palace and Zhu Gaoxu's confidant; The yellow dog was a eunuch left by the Jianwen Dynasty, because Zhu Gaoxu saved the life of his godfather Wu Zhong, and the yellow dog was also loyal to protect it. Zhu Gaoxu left these two people; Only took Wang Gui's godson Cao Fu to travel.

In addition, Zhu Gaoxu asked Duan Xue to stay and stay by Princess Guo Yan's side.

At the turn of summer and autumn, it is the rainy season in Yunnan Province, and it often rains. The Chinese army chose a sunny day to set off, but the ground was still wet, and several streets in the city were even soaked in water. During the Yuan Dynasty, the government used to control the rivers of Kunming City and dig rivers to divert them, but when the rainfall was too heavy, there would still be a lot of water in the city.

But now it's raining, and when it's on the battlefield, it's a season of relatively little rain.

Zhu Gaoxu got up early in the morning, said goodbye to Guo Wei, Yao Ji, and Du Qianrui, and left the harem. Then he took a group of civil and military personnel to the ancestral temple to worship, and then ordered the army to march. The number of people on this trip was only more than 5,000 people, and the Weisuo army was gathering in Dali Mansion; Zhu Gaoxu led the escort army, and he had to go to Dali Mansion first, join forces in one place, and then march to Mengyang Division.

Guo Wei asked about the return date, and Zhu Gaoxu hoped to return to Kunming City before her delivery.

…… From Kunming City to Dali City, the post road is relatively spacious and easy to walk. The army can reach Dali Mansion City in half a month.

The two groups joined forces, and the number of sergeants increased to 10,000. Zhu Gaoxu counted all the people and the strong people, and then counted some more people, numbering 50,000, and led the army out of Dali City and westward along the "Jade Road".

The next road was very difficult to walk, and Zhu Gaoxu divided the army into five roads according to the original plan, and successively marched to Yongchang Mansion. Proceed in batches and try to avoid road congestion.

No wonder Nasijia Tusi was arrogant and destroyed the Ming army's walled city without saying a word. Because the Central Plains Dynasty is going to conquer them, the road is too difficult to walk!

However, Zhu Gaoxu walked among the winding mountains and still did not regret his decision.

A large number of sergeants, centaurs, and baggage were on the road of the valley, like a long snake winding. Fortunately, the forces of Sijia have long since withdrawn from all the areas to the east of Tengchong Qianhu, and the Ming army is still a domestic march in this sparsely populated place, and the danger is not great.

Most of the soldiers in the guard station wore light leather armor and had poor defense, but they took off their clothes to dry at any time. The guards also wore hats and ponies, and looked like grass cowards, but they were more adaptable to the environment.

The guards of the Han Wangfu carried heavy iron armor, but fortunately, the Chinese army got a lot of hats and robes in Yongchang Mansion, so that the guards could also cover them, not only to cover the rain, but also to shade the sun when the sun came out.

People from all walks of life have passed through Tengchong Qianhusuo one after another, which is already the farthest stronghold of the regular army of the Ming Dynasty. Further on, there are almost no Han Chinese to be seen.

But Tengchong is not in the open field, but in a valley with dangerous terrain. The army continued westward, and soon reached the Tusi Mansion (Yingjiang) in the west of the town, which was a large open area, which was very suitable for the army to gather and set up camp.

Zhao Ping reported to Zhu Gaoxu, from the west of the town to continue along the road to the southwest, the terrain is relatively open and flat, but when out of the remaining veins of Hengduan Mountain, there is a section of valley road with dense forest mountains on both sides, and there are often wild beasts...... The army, of course, was not afraid of wild beasts, but it was afraid of the ambushes of the toasts.

Zhu Gaoxu decided to send a few scout teams over first.

Of course, the vanguard scouts were sent by the Weisuo Army, because they had been in the southwest for a long time and were more experienced, and among them were the soldiers who followed Tengchong Qianhu.

They took the small flag as a team, and broke it into pieces, and they did not carry gunpowder and iron pills at all, and even carried little arrows and dry food, but they carried large bags of salt and garlic!

It turns out that what the soldiers are most afraid of is the blood-sucking insects falling from the trees! That kind of small worm burrowing into the flesh is not only terrible, if the worm is broken, the wound will fester, and if it is not cured, you can only wait for death.

The scouts wore hats to guard against them, and then rubbed salt and garlic on their bodies to repel insects. If you get into the flesh and salt it in the wound, it is said that the worms will crawl out on their own.

Zhu Gaoxu ordered all walks of life to camp in this place, and asked the guards to draw scoops in the same way, and use the method of Tengchong Thousand Households to repel insects. As soon as the battalions arrived at night, there was a miasma of smoke everywhere, and everyone burned all kinds of herbs to repel mosquitoes.

…… As long as the army passes through that section of Hengduan Mountain, it can contact the Diao people of the Luchuan Military and Civilian Propaganda Division.

Before this battle, Zhu Gaoxu had already contacted the Diao family and agreed to beat Sijia together. Once the two sides meet, the coalition forces will march towards Mengyangsi, and there will be no more dangers except the woods to stop the pace of the coalition attack!

Seven or eight days later, the men and horses of the five small banners sent out returned to the camp in the west of the town one after another, and nine of them died, one sergeant was bitten to death by a snake, and the other eight were ambushed and stabbed to death by the natives.

Previously, Zhao Ping's men and horses escorted the ore convoy and walked this road, but the Ming army was never attacked and killed by Tusi. The generals and officials unanimously agreed that those natives who ambushed the scouts must be the soldiers of the Si family!

The Ming soldiers were mighty and the battle was very large, and it was obvious that the movement had been learned by Si. However, this place belongs to the territory of the Luchuan Military and Civilian Propaganda Division, not the territory of the Mengyang Division.

After deliberation, Zhu Gaoxu and other civil and military forces decided that Si did not wait for the decisive battle of the Ming army on the side of Mengyang Xuanweisi, but chose to take the initiative to advance to the Tusifu area in the west of the town, wanting to find an opportunity to defeat the Ming army in the dense jungle and narrow valley!

The valley is narrow, and the road here is not much repaired, and it is bumpy. Therefore, the cavalry could not play any role, and Zhu Gaoxu's elite guards were the most ferocious with the iron cavalry, but this battle was useless.

However, in this kind of decisive battle, the Ming army is not afraid of Tusi. Either use infantry to face the enemy, and the Tusi kind of army will definitely be defeated! Either Tusi sent elephant soldiers to charge the battle, but the Ming army carried a large number of firearms.

The chief military officer of Yongchang Mansion suggested that the forward army should go first and seek an opportunity to fight a decisive battle with the main force of Tusi in the valley.

But Zhu Gaoxu refused to admonish, he questioned the scout in detail, and talked with Zhao Ping for a long time, and found that the mountains in front of him were not cliffs, but undulating mountains and forests.

Zhu Gaoxu asserted in the big tent of the Chinese army: "Sijia Tusi is jokingly called monkeys, but they are not monkeys. At that time, the Duke of Qianguo used a large number of firearms in his family, and Zhao Baihu also used firearms to scare off war elephants in the mine. The method of thinking and doing will definitely not be lined up in the valley with elephant soldiers, and we will fight a decisive battle in the open! ”

The crowd listened.

Zhu Gaoxu said again: "The mountains and forests on both sides are the places that the thinking and practice method fancies. However, if we want to compete for the terrain on both sides of the road, we can only fight in the mountains and forests, and then we will suffer a great loss. ”

There was a lot of discussion in the big tent, and Zhu Gaoxu also looked thoughtful, and didn't speak again for a long time.

In any case, the method of thinking and doing has the initiative in choosing the battlefield. The signs of the first battle were already clear, and the battlefield was in the mountains and valleys southwest of the town.
