At this time, Li Fuguo, the superintendent, saw that Yu Zhongtong was so insistent, so he also joined in the persuasion: "The commander-in-chief is so loyal, presumably the emperor will know that this time he fell into the tricks of the Nanzhao barbarians and Tubo, a small setback, no wonder the commander-in-chief. In my opinion, I still listen to everyone's opinions, if the enemy is strong and I am weak, maybe I will return to China first to recuperate, and after the Tubo army retreats, it is not a bad policy to come next year to conquer the crime of Nanzhao Buchen! ｣

Although Xian Yu Zhongtong is faint, he is also an old fox who has been rolling in officialdom for decades. In fact, what he wanted was the words of the superintendent Li Fuguo, and his heart was relieved, so he suppressed his anger and said, "What Gonggong Li said is reasonable. Generals, is the current situation no longer possible? If I am an upright enemy in the Tang Dynasty, neither Nanzhao nor Tubo is my opponent of the Tang Dynasty, but this Tubo has used shameless ambush tricks to cause our army to lose, and our army cannot fight! Anyway, I don't advocate withdrawing from the army, but all the generals have proposed to withdraw from the army, and I can't insist on going my own way, do you say yes or no? ｣

All the generals know that this old bureaucrat is here again to enjoy merit and share the trouble, and they all secretly scold Xian Zhongtong for being despicable and shameless! However, the situation was urgent, and if there was a mistake, the whole army would be in danger, so they all nodded yes.

The generals were discussing when suddenly spies came to report that the enemy had been found in all directions, but the number of people was not large enough to close the circle.

So all the generals begged Xian Yu Zhongtong to act quickly, and if the time was missed, the whole army might be wiped out here.

Xian Yu Zhongtong couldn't make a decision at the moment, and ordered the generals to return to the camp and wait for the notice.

In fact, there is another reason for Xian Yu Zhongtong's delay in making a decision, this expedition he secretly sent his generals and family members to disguise themselves as officers and soldiers to take advantage of the situation to go to the countryside to plunder, and he gained a lot and made a windfall.

Now that he is about to leave for Chengdu, he is worried that the Tang army will withdraw first, and all the property and gold and silk in hand will be lost, so he hopes that the Tang army can contain the Nanzhao and Tubo armies.

After Xian Yu Zhongtong waited for the generals to return to the camp, he urgently ordered the secretary Wu Bingrui to repair two letters, and ordered the fast horse to be sent to the imperial court immediately to ask for instructions.

Another urgent letter was sent to Chengdu, asking Guo Xuji to stay in Jiannan, and then send troops and horses to rescue him.

After the two envoys galloped away, Xian Yu Zhongtong put down a big stone in his heart, so he invited Li Fuguo to the tent to drink and have fun.

The generals of the southern crusade army were anxious, and repeatedly asked to act as soon as possible, but Xian Zhongtong delayed in every way, and in the end, he was actually annoyed and angry, and beheaded Zhang Yanqing, the general of Duanzhou in Lingnan Province, in order to confuse the army's heart, and handed over the Duanzhou soldiers and horses to Li Hui's command, and the generals dared not speak out.

Unexpectedly, within three days, the situation took a sharp turn, the reply has not yet been received, the detectives have found out that Nanzhao and Tubo have come from all directions, Xian Yu Zhongtong did not dare to put up a shelf again, playing official, so he urgently ordered the whole army to retreat, and divided the more than 20,000 people into three divisions, and asked Li Hui to lead 5,000 troops to the palace, and personally led the Chinese army and the supervising army Li Fuguo with a total of 15,000 people as the middle of the march, and Tian Dawei, the deputy envoy of Shannan West Road Observation, led 5,000 troops to open the road first, and marched to Chengdu and Chengcheng.

But it was already too late, and the east and south were surrounded by Long Shengyue, the governor of Nanzhao and Feng Luohao, the general of Nanzhao's guards.

In the west and north, the brave Tibetan warriors led by Wolf Ma and Po Ke Luomi surrounded the Tang army's Dazhai like an iron bucket, and there was no leakage.

Tian Dawei led the elite soldiers of the Tang Dynasty to break through to the northeast violently, and continued to attack three times in a row, with heavy casualties on both sides, but they could not break out of the encirclement, so they had to stick to the place.

Xian Yu Zhongtong was furious at the case, and in order to snub the army's morale and not strive forward, Tian Dawei was removed from his post and placed under supervision, and Xia Yuqing was replaced by the forward general.

Long Shengyue reported heavy casualties to Ge Luo Feng and asked for reinforcements, and Zheng Hui suggested according to the method of the art of war: let go of the eastern route to break through the Tang army, ambush the heavy troops along the Tang army's breakthrough route on the eastern road, and intercept and kill the defeated Tang army along the road.

Once the Tang army is ambushed, it will have no intention of fighting and take the road, and the Nanzhao and Tubo ambushes will be easily captured and killed by the Tang army in one fell swoop.

Ge Luofeng even called it a clever plan, so he sent an envoy to inform the Tibetan commander that the fruit was scorching, and the two sides agreed to make several feints in the south and west and set up more banners and weapons, and pretended to be a threat of heavy troops pressing the border, but in fact secretly reduced the southern Zhao army that surrounded the Tang army in the south, and quietly withdrew most of the Tubo army in the west, and ambushed the heavy troops on the retreat route of the Tang army in the north and east.

Tang Jun thought he had escaped, but in fact he was caught in a net, and it would be difficult to fly when he had wings!

The Tang army went through two major battles, the Battle of Taihe Chengbei and the Cangshan Ambush Battle, and suffered successive defeats, heavy losses, and low morale. Several breakthroughs have not been able to break out, frustrating the spirit, and the current season is in the hot summer, the climate is hot, the Tang army's grain water source has long been cut off, but because the number of soldiers has been greatly reduced, and there are many horses left in the battalion, so there has not been a shortage of food, but drinking water has gradually begun to shortage.

Xia Yuqing, the new pioneer of the Tang Army, discussed with the secretary Bai Shuixiu, that the lack of food was bearable, but the lack of water would make it easy for the army's morale to collapse. If we don't break through quickly, the situation will be out of control.

Xia Yuqing and Bai Shuixiu repeatedly studied the geographical map, Bai Shuixiu suggested that after breaking through from the west, he drove directly to Mengqin City, unexpectedly, along the Lishe River to the southeast to Yinsheng Mansion, bluffing to attack Yinsheng Mansion, Tubo Nanzhao must withdraw the encircled army from the northeast, and our army bypassed Yinsheng Mansion, rushed to the southeast to Jianshui City, and turned sharply to the east in Jianshui City, drove directly to the Wingzi County, and then returned to Jiannan Road from the west to the east.

Xia Yuqing was puzzled why he had to go around in a big circle and not break through directly to the northeast or east? Moreover, the Tubo Nanzhao had strong troops in the south and west, and attacked for several days, which was quite ferocious.

Bai Shuixiu explained: The purpose of the Tubo Southern Zhao attacking our west and south sides for several days was to coerce us to break through to the east or north, but the north and east sides have been reported by spies that there have been a number of gaps, and the troops are empty. Is it not the ambush of our troops in the retreat of our army, intending to wipe me out?

Moreover, Nanzhao Tubo also knows the east and north, which is the closest to the South Road of the Tang Dynasty! Our army will definitely break through from here! Set up an ambush here, our army will return to its heart like an arrow, and will have no fighting spirit, as long as it intercepts along the road, without losing soldiers, it can inflict heavy damage on our army.

Xia Yuqing nodded yes, so she took Bai Shuixiu to the big account to see the commander-in-chief Xian Yu Zhongtong.

The new breakthrough strategy was reported in person, but Xian Yu Zhongtong could not make a decision, so he did not say anything, and after thinking about it, the old bureaucrat could not get the essentials, so he simply ordered the sergeant to beat the drum and raise the account, and invited the generals to come to discuss.
