So, instead of taking a shortcut to enter Nanzhao, he chose the most circuitous and hidden path to enter Nanzhao.

Along the way, avoid the Tang army scouts, spies, from the west side of Cangshan into the mountain, over the Heyun Peak and Nanzhao to get in touch, the Nanzhao army envoy deputy privy Zheng Hui is expected to be Xian Yu Zhongtong strong attack failed, must detour to Cangshan to attack the west gate of Taihe City.

So he decided on a strategy of blocking the front and back, and catching turtles in the urn sandwiched on both sides.

After Zheng Hui discussed with Guojie Scorching Sun, more than 10,000 people of the Zhao army in the south ambushed on the Heyun Peak, more than 40,000 people of the Tubo army ambushed in the south of Jinxi to the top of Heyun Peak, more than 5,000 Tubo troops attacked the Tang army Dazhai, and more than 3,000 Tubo troops lined up outside the west gate of Taihe City, in case the Tang army escaped without a door, and when the exhaustive counterattack, they broke through the encirclement and attacked the west gate.

Because the Tubo soldiers were many and the Heyun Peak mountain was treacherous, it was difficult not to be detected when they set up ambushes everywhere, so the scorching sun divided the 40,000 horses into more than ten ambush sites, some of which were ambushed on both sides of the road, and some were hidden on the high cliffs of the condescending mountains. Some ambush positions are suitable for killing the enemy army with the momentum of ten thousand arrows, while others must attack on foot to annihilate the enemy army.

The whole army took Nanzhao's horn as a signal, and as soon as the horn sounded, they immediately killed together. The Tang army's marching army was extremely long, so it was very easy to cut or divide it to annihilate it, and then extend ten miles up and down from the ambush to the boundary of the sweeping land, so it was necessary to completely annihilate the Tang army.

On the left side of the mountain road, there were 2,000 Tibetan troops led by Po Ke Luomi, and on the other side, 1,500 soldiers led by the deputy general Hu Chi, all of whom went out on foot, hoping to gather and annihilate the Tang army.

Pokoromi heard a bang on the top of Heyun Peak, and immediately led the Tibetan warriors down the mountain to encircle and suppress the Tang army.

The Tang army on the mountain road is the Tang army soldiers of Jiannan Road, although the soldiers of Jiannan Road are all elite soldiers of the Tang Dynasty, but they suddenly encountered a strong enemy in the mountain road, and the team was long, so there was a big chaos.

Pokoromi wielded a long pole and a big sword, as if entering a no-man's land, the soldiers of the Tang Army cracked like waves, no one could stop him, and they retreated one after another.

The deputy general Hu Chi is also unstoppable and rushes straight to the front of the leading general's horse, first cutting off the general, Rongzhou town general Chen Ce is commanding the soldiers and horses to break through, I didn't see that Hu Chi has been killed in front of him, and he was suddenly hacked to death by Hu Chi, and the rest of the army was killed by the Tubo army.

The defeated soldiers of the Tang army fled in all directions, and they could no longer command, and the Tubo soldiers let go of the slaughter, and the Tang army that killed directly flowed like a river of blood, abandoning their armor and throwing away their armor.

After Pokoromi slaughtered the Tang army here, he immediately led 1,500 Tibetan warriors to the mountain, while Hu Chi left 500 Tibetan troops to search for the Tang army in the same place, and the rest of the Tibetan warriors fled with Mu Yeruo to the bottom of the mountain.

Xian Yu Zhongtong led the generals and more than 1,000 soldiers, and was slowly advancing on the mountain road, this old bureaucrat who was an expert in fighting for power and profit, fighting in wars but completely amateur, dragged his nearly seventy-year-old body and was already a little unable to support it.

He was thinking in his heart: If he knew that this mountain road was so difficult, he wouldn't have come!! As long as the deputy marshal Wang Xuan or Tian Dawei comes, can't you get it? Why do you want to go through it yourself??? Li Fuguo, the superintendent of the army, is smarter, so he simply stays in the camp and has a good time.

Anyway, these other people's military exploits that have been obtained by risking death will not be indispensable to him at that time, thinking about it, Xian Yu Zhongtongden actually envied this eunuch.

Just when Xian Yu Zhongtong was muttering in his heart, complaining and complaining, he suddenly heard a sound on the top of Heyun Peak, and after a while, suddenly there were shouts of killing before and after, and then the surrounding valleys echoed with the intersection of blades, the roar of war and the howl of soldiers before they died, the valley shook, the Tang army was chaotic, and it was already noisy, and it was impossible to judge the current situation.

However, there is also great luck in the misfortune, Xian Yu Zhongtong and other troops are not in the ambush circle of the Tubo army, so the Tang army's Chinese army has not yet been attacked, and it can still give orders, but I don't know how long this can last・・・・・・

The various armies ordered to report the emergency military situation like a flowing price, and Xian Yu Zhongtong was dumbfounded and couldn't answer a word, the surrounding military situation was urgent, how could he allow a delay for half a moment???

Finally, the armies of Jiannan Province have been fighting with Tibet for many years, but there is no shortage of commanders, and Sun Changle saw that Xian Yu Zhongtong could not make a difference, so he immediately stepped forward and urgently ordered all departments to immediately go back and tell the attacked departments not to panic, quickly leave the mountain road, avoid the open plains and open spaces, find hidden places in the mountains and forests, and immediately assemble all the soldiers, regardless of the subordinate state roads, first stick to the place, and wait for the opportunity to break through to the mountainside, if the situation is urgent, you can act arbitrarily and alone, do not ask for instructions.

Sun Changle and Wu Bingrui, the secretary of the shogunate, hurriedly found several locations on the mountainside on the geographical map to find several places where they could assemble, and were about to send a herald to convey the military order when the Tibetan army attacked.

The mastiff commander led thousands of soldiers and horses to surround and kill. Xian Yu Zhongtong saw that the Tubo army was like a fierce tiger, coming all over the mountains, so he rode his horse and fled first, leaving all the responsibility of command to Sun Changle, and fled into the mountains and forests, Wu Bingrui, the shogunate secretary, immediately asked the commander-in-chief under the pretext, and also abandoned his duties and followed some generals to follow Xian Yu Zhongtong, and the army saw the commander-in-chief riding his horse and fled first, and the army's heart collapsed in an instant, and fled in all directions.

Sun Changle waited for the secretary Wu Bingrui to report to the commander-in-chief for instructions, knowing that this guy would definitely abandon his duties and run away. So, he didn't wait, and hurriedly discussed with other generals how to break through the siege, and organized the Tang army to resist the enemy. How could the Tang army be scattered, almost no will to fight, the armies did not follow the team, looked around, looking for an opportunity to escape, only the remaining Sun Fu generals and more than 100 soldiers and horses obeyed the command.

Wolf Ma Department General Dejie led the troops into the Tang army column, three Tang generals patted the horse to welcome, Dejie was mighty, even stabbed three Tang generals off the horse, unstoppable, the remaining Tang soldiers were even more scattered, running around, Dejie led the troops to kill, the corpses of the Tang army were all over the field, and the blood flowed like a river.

Sun Changle led the remnants of the defeated soldiers to retreat while fighting, wanting to retreat into the mountains and forests, but the Tubo army was already surrounded on all sides, and the sound of shouting and killing was endless.

Sun Changle and several Tang generals fought to the last moment, the soldiers around him were killed and wounded, the outcome was defeated and died or captured and humiliated, Sun Changle saw that all the generals were martyred, so he roared violently, raised the sword, and strangled the neck, blood splashed on the grass stained with the blood of the generals and soldiers, killing Shengren, in order to repay the country, the Tang family next to him saw the master of the horizontal sword self-cutting, after all crying, the horizontal knife committed suicide, no one was spared!
