The army went on the road, marched in sequence, and served as the vanguard with more than 10,000 soldiers and horses in the middle of the Qianzhong Road, responsible for opening the road in the mountains, building bridges in case of water, digging mountains and breaking stones, and not hindering them.

Jiannan Road is the marching middle army, Shannan West Road is the marching left guard, Jiangnan West Road is the marching right guard, and Lingnan Road is the marching rear guard.

Along the way, the military flag is displayed, the army stretches for dozens of miles, the military is prosperous, the army is strong, the people along the road are closed, there is no one everywhere, no one comes out to meet the king, but one after another sees the fleeing people, with their families and dependents, to the north.

He Yu was puzzled in his heart, and when he talked privately with his friend Lu Peiye, he felt that it was extremely unusual, could it be that the people did not support this southern expedition?

On August 22, Ge Luofeng sent people to express his gratitude for the crime for the second time, and promised to return the Tang land he had originally occupied, but Xian Yu Zhongtong refused again, and relied on the military power to ask Ge Luofeng to surrender immediately.

Several times in a row, Nanzhao King Ge Luo Feng sent envoys to ask for peace and apologize, but repeatedly returned for Xian Yu Zhongtong's insults.

For the last time, the envoy brought a message from Nanzhao Wang Ge Luofeng, if the Tang Dynasty repeatedly threatened, Nanzhao had no choice but to ask for help from Tubo, at that time, the entire southern part of Jiannan Road will no longer be owned by the Tang Dynasty, be careful! Be careful!

How can Xian Yu Zhongtong listen to such words! He not only tore up the national letters, but also ordered the samurai to cut off the heads of the envoys of Nanzhao, and tattooed words on the faces of his followers to insult the king of Nanzhao, and ordered his followers to hold the head of the envoys, beat the camp with a random stick, and drive back to Nanzhao.

When Ming Xiang heard that there was such a thing as beheading the envoy and tearing the book and stabbing the word to humiliate the king of Nanzhao, he was very unimpressed, and privately complained to the generals of Jiangnan and Xidao: "There is a way: the two countries fight each other, and they do not kill the envoys. What kind of hero is bullying an unarmed person? Living in a safe place, advocating the courage of war, and using the blood of others to prove his loyalty and patriotism, his grandmother's, I can't do this kind of thing!

Unexpectedly, Xie Zhiwei, the Chenzhou crusade, in order to seek promotion, secretly told Xian Yu Zhongtong these words, Xian Yu Zhongtong had a small amount of energy, so he hated Mingxiang very much, and wanted to kill him in his heart, so he conspired with Deputy Marshal Li Hui and staff officer Wu Bingrui day and night to assassinate Mingxiang・・・・・・

The further the army went south, the more and more refugees came on the way, dragging families and dependents, bringing the old and the young to help them. The family was in a good way, the roads were jammed, and the imperial court conscripted and suppressed the soldiers and horses of the Southern Zhao, but it was difficult to advance.

Xian Yu Zhongtong was furious when he saw this, and ordered the vanguard general of Qianzhong Dao, holding a stick, if there was anyone who blocked the marching road, he would be punished with a stick, whether he lived or died.

If the general soldiers and horses march on the official road, the official road is vast, and the fleeing people can also avoid on both sides of the road, but the more the southern expeditionary army goes south, the closer to the border, the less developed the road is, the official road has not been built here, there are many small roads, the southern expeditionary army has to come all over the mountains, so where can the fleeing people find to avoid the official army?

The fleeing people abandoned their family business and gave up their daily livelihoods, and now it is the height of summer, the weather is hot, and the people are already miserable. During the fleeing season, the soldiers of the brigade marched to open the way, and the people had no way to hide, and those who walked slowly were driven by sticks, and some were killed, and the soldiers complained and the people were angry, and they cried. Some people took refuge in the mountains, forests and wilderness, only to hear the scattered people, calling for their children and mothers, looking for their sons and looking for their masters, so that they were not miserable.

He Yuzhi and Lu Peiye stopped a few frightened people on the side of the road who couldn't avoid it, and took some dry food, wine and food, so as to comfort them.

He Yuzhi asked: "This eldest brother, we are the army sent by the imperial court to conquer Nanzhao, the thunder army, the evening is coming, Nanzhao will definitely surrender soon, and it will not be delayed, why should you and other good people panic?" Why bother to abandon your family and children and flee? ｣

This common man was in tattered clothes, emaciated, and only in his thirties, and after gobbling it up for a while, he slowly said, "Master Jun, do you know that at the end of last year, since Nanzhao invaded Yaozhou Mansion and killed the assassin Zhang Qiantuo, he has turned his back on the Tang Dynasty. Successively conquered the southern part of Jiannan Province and the state of Jianmi (i.e., Fanzhou), a total of 20 or 30 states. It's not fun! I think it will take a long time to drive them out of the Tang Dynasty! ｣

Lu Peiye exclaimed, "Twenty or thirty states, so many states and counties have been seized in the southwest!? ｣

The people said, "Yes! I thought that Nanzhao was just snatching, and then left, but I didn't expect that Nanzhao had occupied it for a long time. The state highway of Nanzhao was also established, obviously to occupy our Tang territory for a long time!! ｣

He Yuzhi, well: "What this big brother said is. If so, why should you people move here? ｣

The people peeked in all directions, and when they saw that there were no other soldiers on the left, they said, "Master Jun, we are not afraid of Nanzhao, we are afraid of war!" Besides, Jiannan Jiedu makes Xianyu adults, greedy and violent, forcibly expropriated, and the common people are unbearable, or Nanzhao is better! Besides, if it wasn't for the war, why would I go back to the Tang Dynasty..." A woman next to her hurriedly covered the middle-aged man's mouth: "Are you going to die? Is it possible to say these words? If you let people hear, will you live? Master Jun, Master Jun, our head has a fever and his brain is burned out, so you can treat him as crazy talk! ｣

The thin middle-aged man was shocked: "Don't say it! Do not say! If you want to understand the situation, you might as well ask the people in front of you, and they will explain it to you. I'm leaving! With that, the man hurriedly helped his wife to flee.

He Yuzhi and Lu Peiye pondered in their hearts and felt that this expedition was very wrong, but they didn't announce it. I wanted to find some more people to interrogate, but I never had the opportunity again.

Xian Yu Zhongtong saw that the refugees were congested with the roads, and the army was difficult to march, so he and the generals decided to divide the troops into three ways to attack Nanzhao, and after entering Nanzhao, they directly took Taihe City, the capital of Nanzhao, and did not fight for a city and a town with Nanzhao, and directly attacked the enemy's place to save, as long as Taihe City was broken, those states and counties that were taken away would naturally return to the hands of the Tang Dynasty.

In the first North Route Army, the commander-in-chief Xian Yu Zhongtong led 25,000 soldiers from the Jiannan Road Headquarters and 10,000 soldiers and horses from Shannan West Road, a total of 35,000 men and horses, from Qingxi Pass to Nanzhao. This road is the main force and the strongest combat power.

In the second route south route army, deputy marshal Wang Zhijin led 10,000 soldiers in Qianzhong Road and 20,000 soldiers and horses in Jiangnan West Road, a total of 30,000 people detoured to the south, took the first road, and attacked the border of central Yunnan.

In the Third Route Army, Deputy Marshal Li Hui led 15,000 soldiers from Lingnan Province and 5,000 troops from Li Hui's headquarters in Jiannan Province, a total of 20,000 people, to take the same road and cooperate with the North Route Army to attack the Erhai border.

The three-way army will meet under Taihe City on September 20 to besiege Taihe City together.
