The Tang army used powerful siege equipment such as bed crossbows to violently attack Taihe City, but Taihe City also sent stones to counterattack, and this day's offensive was aimed at testing the defense of Taihe City, so there was no intention of attacking the city on a large scale.

The two armies threw stones at each other and fired crossbow arrows, but there was no close combat, and at dusk the rain became heavier, and the two armies withdrew.

Regarding the disposal of Luo Duohan's body, there were disputes within the Tang army, and Ju Xingyuan advocated the burial and erection of a monument, but the recruitment made Wang Xuan weaken the morale of the Tang army because he killed his beloved general Wang Xingyun and many Tang generals. Therefore, he insisted on beheading the corpse and hanging bamboo poles on the head to humiliate the Southern Zhao army, and Xian Yu Zhongtong also agreed with Wang Xuan's opinion.

Although Ju Xingyuan has been brave and famous, although he has military exploits, he must be a small official and humble and cannot argue with Xian Yu Zhongtong and others, so after some arguments, he was transferred to the rear army to manage grain and grass and guard the army's Dazhai.

However, Xian Yu Zhongtong didn't pay attention to it, according to him, Luo Duohan is dead, and Ju Xingyuan's role is not great, anyway, these generals come and go as soon as they are recruited, and they are not bad for such a one.

Ju Xingyuan was originally a pioneer general of Jiangnan West Road, and was transferred to the rear army in charge of grain and grass, although the head of grain and grass is also an extremely important errand, but Ju Xingyuan, a fierce general, was arranged here, obviously being left out in the cold, and did not want him to make meritorious service again.

Ju Xingyuan was originally a person with a strong heart for fame, and losing the opportunity to make meritorious contributions also means that the book has the opportunity to rise and become famous, which is naturally resentful. Ming Xiang saw that Ju Xingyuan was transferred to the rear army, so he came to express his condolences, and saw that Ju Xingyuan only led more than 600 soldiers from the headquarters and deputy general Fang Yuanju, and was afraid that the military strength was weak, so he allocated more than 400 soldiers from Jiangnan West Road to him, and barely scraped together a thousand soldiers and horses.

Luo Duohan's corpse was disposed of according to Wang Xuan's method, and when the city was attacked on the second day, Xian Yu Zhongtong ordered the sergeants to insult Luo Feng, the king of Nanzhao, and hung Luo Duohan's head on a bamboo pole to humiliate him, and the soldiers of the Tang army were foul language in front of the battle, laughing and scolding, and wanted to lure the Nanzhao army out of the city to fight.

Qiao Yingchang was scheming and strictly forbade the Nanzhao soldiers to go out of the city to fight, but instead gave good words and advice to the Nanzhao soldiers, asking them to hold back their anger and wait for the fighter to turn. Sure enough, although Tang Jun's actions satisfied the psychology of Xian Yu Zhongtong and others to humiliate their opponents, it instead inspired the determination of the Nanzhao army to defend the country to the death, especially the humiliation of Luo Duohan's head, which made the Nanzhao soldiers resentful.

"Luo Duohan is a famous brave general of our country, and now he was killed in a single battle, and he should be treated with due respect and treatment, but Tang Guo refused to return the body and did not want to bury the body, but instead hung his head on a bamboo pole and let it be exposed to the sun and rain, wantonly insulting, which is really hateful! We want to avenge Luo Duohan, and we want to kill all the Tang people, leaving no one behind. Long Shengyue and Feng Luohao and other Nanzhao generals told their soldiers so.

The generals of Nanzhao were also grieved and indignant, and vowed to kill all the Tang soldiers for Luo Duohan in order to avenge the great revenge.

For several days in a row, the Tang army used bed crossbows and stone throwers to weaken the city defense, and it was not until the fourth day that the Tang army sent ladder trucks and flying ladders to attack Taihe City, in order to break the city.

However, the Nanzhao army was on the city wall below the general Feng Luohao, struggling to defend the city, and the Nanzhao army was sufficient, every Nanzhao warrior regarded death as home, not only held the city wall, but also sent cavalry from the east city gate several times to counterattack, finally the Tang army was well-trained and stuck to the formation, so the Nanzhao army did not take advantage.

The Tang army attacked the city for several days, killing and wounding about hundreds of people, but did not even capture a section of the city wall.

Xian Yu Zhongtong led the main force with Tian Dawei and Wang Xuan as deputy commanders, and led more than 47,000 soldiers and horses to take the Cangshan path to attack the west gate of Taihe City under Cangshan Mountain.

Li Hui led his headquarters and Miao Yijie's Lingnan Road elite soldiers, totaling more than 15,000 soldiers and horses, to feint and attack the northern city gate.

There are more than 1,000 remaining soldiers and horses, led by Ju Xingyuan, who stayed in the camp more than 20 miles away from Taihe City and the whole army's grain and grass.

Cangshan is quite towering, the mountain peaks are extended, the terrain is unique, there are 19 peaks and 18 streams, two peaks are sandwiched by a stream, the Tang army needs to enter from Baiyun Peak and go down the mountain through Jinxi to Heyun Peak to the west of Yamato City.

In the early morning of this day, the sky is not yet bright, the night is gray, although it has not rained, but there is a trend of mountain rain coming, and the mountain road is still a little muddy because of the rain a few days ago.

Xian Yu Zhongtong took Jiangnan West Road as the vanguard, the commander of the army was Ming Xiang, Xian Yu Zhongtong led the main force of Jiannan Road and Qianzhong Road as the Chinese army, Tian Dawei led Shannan West Road as the rearguard, the whole army except for the horses that the generals rode and transported small siege equipment and military supplies, the rest of the military horses and pack horses stayed in the camp, and the whole army entered Cangshan on foot.

Due to the large number of people in the whole army, and the mountain road is sometimes wide and sometimes narrow, and the narrowest place can only accommodate two horsemen in parallel, so it advances in a long snake formation, and the Tang army winds for more than dozens of miles.

The vanguard of the Tang Army walked for more than three hours, just bypassed the top of Heyun Peak, went to a place, the terrain was relatively gentle, the mountain road began to widen, although the mountain path was still narrow sometimes, but it was already feasible to have a four-horse carriage, it was estimated that after walking for a while, it could go downhill, and the west gate of Taihe City was under the mountain.

The Datang Pioneer Sergeants were all excited when they saw that they were about to go downhill. He Yuzhi and Zou Yueqi became friends after fighting side by side in the last battle in the north of the city.

The two rode side by side, and Zou Yueqi said in a low voice, "Zhong Yu, I have great doubts about this roundabout Cangshan march! ｣

He Yuzhi also said in a low voice: "Brother Xiaoming (Zou Yueqi), what are your doubts? But it doesn't hurt to say it! ｣

Zou Yueqi said, "His aunt's, how can he have a march that stretches for dozens of miles to meet the enemy? If we encounter an enemy ambush, we will not be like fish and meat, and let others slaughter them! ｣

He Yuzhi nodded in agreement, but did not answer.

Lu Peiye interjected on the side: "According to Xiaoming's opinion, how should this be solved? ｣

"In my opinion, I shouldn't have walked this mountain path at all! Zou Yueqi said in a low voice: "The commander-in-chief did not send someone to carefully survey the terrain here, only sent some sentry horses to respond to the story, only a few miles up the mountain, after taking a casual look, he went back to Dazhai to report that there was no enemy, isn't this a joke with the lives of the soldiers of the whole army?" It would be unwise to take the liberty of taking a detour from here without investigating it in detail. Our army is on the march, and the queue is so long, if it is attacked, it will not be able to form a formation to protect itself, and there will be no time to rescue.
