Thousands of arrows were shot towards the city, and the Tubo soldiers were busy hiding under the battlements to avoid the arrows, but they heard a clanging sound like fried beans, and the arrows shot by the Tang army were all shot on the outer wall of the city wall, and a cloud of dust rose on the rammed earth wall.

"Hahaha, the archery skills of these Tang soldiers are really bad, and their strength is limited, so they can't even shoot at the head of the city." One of the generals laughed.

The Tibetan soldiers poked their heads out, but when they saw that the Tang army under the city only shot a round of arrows, they all hid under the big shield and retreated.

"Just to shoot a round of arrows? The Tang people are really ridiculous. Everyone laughed and said, seeing that the Tang soldiers were still walking with big shields, like a group of turtles crawling on the ground, the Tubo soldiers did not shoot arrows, and laughed at the front and back of the city.

However, they soon noticed that something was wrong, and there were colorful clouds floating up from under the walls, and red, purple, yellow, and black smoke were slowly rising along the city walls, and soon dispersed above the city walls. The soldiers close to the battlements stared curiously at the colorful smoke and dust floating in front of them, and suddenly felt dizzy and disgusted.

At the same time, the other Tibetan soldiers at the head of the city also felt unwell, and soon they also began to have headaches and stinging eyes. And the colored smoke was rapidly enveloping the city walls.

I don't know who shouted: "It's a poisonous miasma, it's a poisonous miasma, get out of these colored smokes, this is the poisonous miasma of the Nanzhao people." ”

This voice suddenly seemed to stab a hornet's nest, and the soldiers immediately cried and shouted to their mothers to scatter and hide. Everyone knows that the Nanzhao people have a poisonous miasma, and those who are hit by the miasma will be dizzy, dizzy, nauseated, or nauseated, blind, deaf, or even become idiots or simply be poisoned to death, which is according to different types of miasma, and the symptoms are also different. The colorful smoke must be a different miasma, and the mixture is basically hopeless. Although I don't understand how the Tang army cast the poisonous miasma under the city, I don't have time to think about it now, but I have to quickly escape from this brilliant but deadly poisonous miasma smoke cloud.

However, too many soldiers and horses had been mobilized to gather on both sides of the tower, so that it was overcrowded within hundreds of paces on both sides of the tower. At this moment, the smoke is shrouded, and everyone is lost in the miasma, and they scatter in a panic, and people become the only obstacle to escape. For a while, above the city, you pushed me, squeezed me, cried father, and called mother, and the Tibetan soldiers pushed each other desperately and did not know the direction with the intention of fleeing.

Many people fell to the ground without a chance to escape, and others trampled on them regardless of the fact that they were still alive. In order to escape from the suffocating and deadly poisonous miasma, some people even did not hesitate to jump over the battlements and jump off the high city walls, ending their suffering completely. There are also people who are squeezed by others on the pile, and then they are squeezed alive and fall off the city wall and fall to their deaths. The walls on both sides of the city gate suddenly became a hellish Shura field shrouded in a cloud of death.

It was indeed a poisonous miasma, and it was all the poisonous miasma that Ge Luofeng had collected in the past year. The collection of the miasma is extremely dangerous and difficult, although the Jiannan army has long had gas masks to crack the attack of the miasma, but as a means of war at the bottom of the box of the soldiers and horses of the Nanzhao State, the various ethnic groups of the Nanzhao still have to collect these miasma for wartime use. It may not be useful to fight against the Tang Army, and these poisonous miasma are needed as a means to fight with other countries and even in the nest, so Ge Luofeng still ordered people to collect the poisonous miasma.

In a year, the poison miasma they collected was very limited, only a few thousand poison sacs were collected, and all of them were equipped in Ge Luofeng's personal guards. Last night, after discussing the timing of the siege, Wang Yuan found Ge Luofeng and hoped that he could launch a poisonous miasma siege. The miasma siege is not easy, the miasma in the open area is restricted by many factors, the wind is too strong will quickly blow away the miasma, and the range is too large to reduce the effect of the miasma, so this is actually just an alternative siege plan. After Wang Yuan destroyed the arrow towers on both sides of the city gate with his crossbow, he decided to use this cruel siege method when he found that a large number of Tubo soldiers and horses were gathered on both sides of the city gate.

Although Wang Yuan has always felt that it seems immoral to attack with a poisonous miasma, this is similar to the biological weapon attack in later generations, which is generally an inhumane act. However, the current battle to attack the city was limited by the lack of siege weapons and the urgency of time, and Wang Yuan could not care about those so-called moral things. If he can reduce his own losses and take this city in one fell swoop, Wang Yuan will try it by any means.

The 3,000 shield soldiers of the Southern Army of the Sword were covered by the archers of the Nanzhao Kingdom wearing poisonous miasma sacs, and after the embarrassment dodged the arrows of the rainstorm at the head of the city, the barbarians of the Nanzhao Kingdom only had the opportunity to shoot this round of arrows. But this round alone is enough.

Arrows with poison sacs tied to them do not need to be shot at the top of the city, the only requirement is that they cannot be shot in the air. The best place to do this is the city wall beneath the battlements. The moment the arrow hit the city wall, it burst out with colorful smoke clouds, and these poisonous mist slowly rose until all the Tibetan soldiers and horses at the head of the city were enveloped in it, and the desired effect was achieved.

The head of the city was shrouded in terrifying colored clouds, and among the clouds, the Tibetan soldiers fell from the city one after another like dumplings, and the panicked shouts of the soldiers at the head of the city could be heard clearly. In the Tang Army's formation, Wang Yuan had a sneer on the corner of his mouth, and the muscles on his face trembled slightly, he didn't want to see this kind of terrifying scene, but as the commander-in-chief, even if he did something against the way of heaven, he couldn't reveal half of it.

"It's cruel." Gongsun Lan, who was beside Wang Yuan, said softly.

This sentence also represents the voice of many generals and soldiers. Especially Song Jiangong, he has learned the power of the miasma, when he fought with Nanzhao, on the south bank of the Feidu Bridge, because of the leakage of gas masks, thousands of soldiers died in the miasma, he can understand the horror of being in the miasma.

"To be merciful to one's enemies is to be cruel to oneself." Wang Yuan said quietly.

Ge Luofeng nodded and said, "That's right, how can there be any cruelty on the battlefield?" The same is to kill, what is the difference between killing with a sword and killing with a miasma? ”

Gongsun Lan nodded slightly and said, "It's also true, it's all killing, there's no difference." ”

Ge Luofeng said: "Brother-in-law, you can launch a siege, the poisonous miasma will soon disperse, you must seize this precious opportunity." ”

Wang Yuan nodded, and said to Song Jiangong in a deep voice: "General Song, give the order to attack the city, and after attacking the city, quickly solve the pain of those poisoned Tubo soldiers." ”

Song Jiangong surrendered his promise and issued the order to attack, and for a time the war drums were ringing, and the sound of shouting and killing resounded in the sky. More than 20,000 Tang troops rushed to both sides of the city gate shrouded in colorful clouds. More than a dozen rushing cars also rushed up the hill and went straight to the city gate under the impetus of dozens of strong men.

The Tibetan defenders on the city wall on both sides of the city gate lost their defensive strength, and the Tibetan soldiers and horses on the surrounding city walls could not rush to this section of the city wall to defend. Even without the miasma, they would not be able to break through the torrent of Tibetan soldiers who were fleeing towards the walls on both sides. The main direction of the Tang army's attack was within a distance of hundreds of steps on both sides of the city gate, which had lost its defensive ability after the poisonous miasma.

The miasma slowly dissipated, but a large number of Tang troops had already rushed to the city. The castle on the hillside was protected by strong and tall walls, but the most basic defense they lacked was the moat. There were only wide, deep moats on the sides of their walls, but there was only a shallow layer of water in the moats. Because there was no water on the hillside, this also caused the Tang army to lose the last obstacle when attacking the city, and rushed directly to the city.

Countless ladders hit the city, and when the giant wooden chariot began to pound against the gate, the defenders on the walls on both sides were able to rush over to defend. But it's already too late. The number of Tang troops who climbed the city wall on countless ladders was already too large, and it was enough to organize a defensive line against the Tibetan soldiers. As time passed, more and more Tang troops climbed the city and fought with the Tibetan soldiers on the city walls.

Finally, the monotonous sound of the car crashing against the city gate was replaced by a booming crash, and the Tang army under the city cheered loudly, and the city gate was broken. The Tibetan defenders at the head of the city were as pale as earth, and everyone understood: the general trend has gone, and the city cannot be defended.

General Dorjee was covered in blood, and led the Tubo soldiers around him to fight with the Jiannan soldiers on the city wall. Hearing the news of the city gate being broken, Dorjee's heart was like ashes. In the blink of an eye, seeing Meng Tu Ke who was huddled under the battlements with his hands tied, Dorjee strode over and raised his blood-stained scimitar.

"Before I die, I will kill you to avenge the Iron Blade General." Dorjee said coldly.

Meng Tuke waved his hand tied by the rope and shouted: "General Dorjee, I have no regrets if you kill me, but if you die at your hands, I might as well kill a few Tang soldiers who died at the hands of Tang Jun, and also forgive my sins for myself and ask for the forgiveness of the reincarnation Buddha." My last request is to ask you to let me die in battle with the Tang Army and wash away my shame. ”

Dorjee frowned and said, "You have such guts? ”

Mengtu exclaimed: "I'm going to die anyway, Dorjee, won't you even give me this chance?" ”

Dorjee thought for a while and said, "That's it, give you a chance to wash away your shame." If you can kill a few more Tang soldiers, when we go to the underworld to meet General Iron Blade, I can also ask for a couple of words for you, and ask General Iron Blade to punish you lightly. ”

"That's exactly what it is," he exclaimed. ”

Dorjee swung his knife to cut off the rope on Meng Tuke's hand, raised his foot and kicked a scimitar on the ground to Meng Tuke's feet, and said loudly: "Rush forward with me to kill, there is a general of the Tang Army in front, let's kill him." ”

Mengtu Ke vaguely agreed, reached out and grabbed the scimitar and stood up, Dorjee turned around and rushed towards the Tang soldiers rushing on the opposite side, and just took a step, he suddenly felt a tingling pain in his chest. When he looked down, he saw the tip of a blood-dripping scimitar sticking out of his chest, and when he looked back in horror, he saw the face of Mengtu gritting his teeth and smiling.

"Dorjee, you want me to die, but don't blame me for being unkind. I could have killed the Iron Blade General if he got in the way of my escape, let alone you. If you want to be martyred, you go by yourself, but Lao Tzu won't go with you to die. These were the last words Dorjee heard, and then his body was kicked off the city by Meng Tukefei, fell on the dry ground gravel, bounced twice, and did not move.

Mengtu threw down his scimitar and fled backwards as quickly as he could, descending the city wall through a city staircase, finding a secluded place to take off all his armor and clothes, and disappearing into a dilapidated house with his hair braided and his clothes dirty.
