The huge trebuchet 'squeaked' and tightened, and with the sergeant's command, the huge boulder was thrown up the cliff and hit the walls of the stone castle city, raising a cloud of dust, like a small wave on the sea.

But more than a hundred trebuchets shot out at the same time, and the dense stones 'crackled!' 'Hitting the city walls, the dust and mist are raised, and large pieces of rubble fall from the cliffs, which is magnificent.

But this kind of attack has no effect on conquering the stone fort city, the strong castle is built on the red ridge, surrounded by cliffs, only a narrow passage to go up, it can be said that 'a husband is an official, ten thousand people do not open', Tianbao eight years, four hundred Tubo troops guarded this fort, but Longyou Jiedu made Ge Shuhan to take the castle at the cost of tens of thousands of dead and wounded, which shows the difficulty of taking this fort.

Zhang Huan has been attacking for ten days, he retreated from time to time to lure Ma Chongying to chase, seeing that the other party was not fooled, but immediately turned back to attack, but the real attack was only two, after hundreds of dead and wounded, he immediately stopped the attack, and used stone cannons and flying crossbows to attack, but Ma Chongying never held out, both of them had a little tacit, one was buying time for the Tang army to evacuate from all over Hehuang, and the other was waiting for reinforcements, preparing for a large-scale counterattack.

In the middle of the night, the Tang army was quietly packing up their belongings and preparing to retreat, Zhang Huan stood beside the tent, unwillingly looking at the stone castle city shrouded in night, this strong castle he has never been able to take, but he has no time, the situation is more critical than he imagined, he just got an urgent report, Tubo Zampu personally led 100,000 troops from the direction of Huixi Fort to kill, ready to evacuate to Longyou 5,000 Dangxiang army was surrounded by enemy troops in Longzhi County, has surrendered to the Tubo army, and now the Tubo forward has been killed to Huangshui.

There is no going back.

Now I can only take Ningsai County from the south, and take the road where the scout soldier Liu Shuai fled back to Longyou, but even if I take this road, it is estimated that it is also full of hardships.

"Governor, get ready to go." Du Mei saw that Zhang Huan's eyes were full of unwillingness, so he comforted him and said, "As long as we save our strength, we will kill it again in a few years." ”

Zhang Huan didn't speak, he stared at Shibao City, and suddenly said, "You said that if we don't retreat from the original way, will Ma Chongying be in a hurry to catch up?" ”

"What do you mean?" Du Mei suddenly understood Zhang Huandi's thoughts.

Zhang Huan smiled faintly and said, "I have been fighting for more than a month. But he has never been able to see this famous Tibetan general, how can he not leave him a souvenir? ”

Early the next morning. Ma Chongying, as usual, stood on the castle and watched the movements of the Tang army. Three days ago, the 30,000 troops who had arrived from the Jiuqu region to support had quietly arrived in Shibao City, and now, he needed to calculate the time and wait for Zampu to cut off Zhang Huan's back route.

Ma Chongying was recalled by Chi Song Dezan to reprimand after the failure of the attack on Huixi Fort, and it was then that he learned of Zampu's plan to attack the Tang Dynasty. Speaking from the heart. He was not optimistic about Zampu's plan, after all, attacking Longyou was completely different from attacking Hexi. But he also knew that Tubo had been fighting for many years, and his financial resources were gradually drying up, and Zampu had no choice but to raise the idea of the Eastern Crusade.

Although Trisong Detsen did not know in advance that Zhang Huan would attack Hehuang. But Ma Chongying knew that Zampu would definitely take the opportunity to cut off Zhang Huan's back road, and in terms of time, he should have succeeded.

"Governor, it's a little strange." The deputy general next to him, Xi Dazang, suddenly discovered a clue.

"What's weird?"

"Governor, please see." Siddhart pointed at the trebuchet from afar and said, "The stones projected a few days ago can still reach the top of the city, but from this morning to now, the highest piece has only hit the middle of the city wall, and it seems that only half of the stone cannons are projecting. ”

Ma Chongying was reminded, he carefully inspected the situation, and indeed the stones shot were lazy, not at all as strong as yesterday's whistling, he knew that this kind of stone cannon was made by Zhang Huan temporarily, and it lacked clever parts with the help of force, and a stone cannon needed at least two hundred people to fill it, and now this lack of strength can only show that the Tang army does not have so many people to attack.

"Could it be that Zhang Huan has already started to retreat?" With the thought in mind, Ma Chongying immediately ran to the highest watchtower and threw himself on the battlements to look into the distance.

In the distance, I saw that the Tang military camp was still there a few miles away, but it was very quiet, and there was no such excitement as in the past. Ma Chongying repeatedly warned himself to beware of Zhang Huan's plan.

From early in the morning, Ma Chongying watched the changes of the Tang army motionlessly, the stones thrown became more and more sparse, and the strength became weaker and weaker, until noon, the Tang army finally stopped attacking.

Hundreds of stone cannons are placed in the open field, there is no Tang army in sight, and the camp tent is still the same, according to reason, this is the time for the Tang army to go back to eat.

Ma Chongying stared closely at the west side of the tent, where there was smoke burning every day, but now there was no movement at all, and suddenly, a thin wisp of green smoke floated up, circling weakly upward.

"Soldiers!" Ma Chongying finally made up his mind that the Tang army had really withdrawn, he waved his arms excitedly and shouted repeatedly, "Prepare for the pursuit." ”

A quarter of an hour later, the gate of Shibao City opened, a group of Tubo soldiers swarmed out, Ma Chongying took the lead, led a thousand people to rush into the Tang army camp tent, sure enough, the Tang army camp was empty, there was no person, the grain and grass were not taken away, where the green smoke was lit just now, but a few sheep were gnawing on the grass, when they gnawed a rope, some burning charcoal fell on a pile of hay, and the Chinese books in the shuai tent were only half burned, and there were some scattered copper coins on the ground in many camp tents, and it can be seen that the Tang army retreated, even the money was distributed to the soldiers.

"Governor, could it be another trick by the enemy to lure troops?" Si Dazang asked with some unease.

"My reinforcements have arrived, so why be afraid of him." Ma Chongying couldn't help but laugh loudly: "Didn't you see his escape route?" He also knew that the back road was cut off. ”

He turned over on his horse, pointed his whip at the east and said: "Give me the starry night pursuit, kill Zhang Huan, the official will be promoted to the third level, and the reward will be 100,000 yuan." ”

Tens of thousands of Tibetan troops fought bravely, under the leadership of Ma Chongying, and followed the trajectory of the Tang army's retreat, frantically chasing eastward.

But just half a day after Ma Chongying chased out, a group of 3,000 cavalry dressed in Tubo military uniforms quietly approached from behind Shibao City, and this army was naturally Wang Siyu's 3,000 cavalry. After they washed Wanxiu City in blood, they chased all the way, and arrived at Shibao City with 30,000 Tibetan reinforcements as early as three days ago.

Although it was ten days later than Zhang Huan's prescribed time, but if he didn't take Shibao City, he Wang Siyu would never go back, it was relatively easy to enter the fort from the south of Shibao City, the cliff was not as steep as the north, and the road was slightly wider, which could accommodate five people in parallel.

In order to take Shibao City, Wang Siyu specially prepared hundreds of carriages disguised as the logistics army of the Tubo people. He also obtained dozens of Han Chinese slaves who could speak Tubo from Wanxiu City, and when he found out that the Tubo army had left the castle. Wang Siyu knew that the opportunity had come.

He immediately urged hundreds of carriages to slowly move towards the city gates.

At this time, there were only a thousand garrisons left in the city, led by a commander of thousands. At this time, a Tibetan soldier came to report that a logistics army had come and was calling the door.

The commander walked quickly to the head of the city, leaned on the battlements and looked down, only to see hundreds of carriages parked under the long stone steps in the hazy moonlight. It's full of stuff. Even better, there seemed to be a woman looming in the moonlight.

"We are here from Wanxiu City and have been ordered to deliver supplies." A loud-voiced Tibetan soldier shouted under the city gate: "There are still fifty women. ”

The defenders of the city had already seen the woman. All of them were itching, and they all looked at the leader with blank eyes, and no one doubted that the Tang army would be killed from behind. This is something that never happens.

But the commander was very cautious, and instead of opening the door at once, he cried out:

"You have paperwork!"

"Yes!" As soon as the words fell, a severed arrow was shot at the head of the city, with a document inserted on it, and the commander opened it and looked at it, sure enough, it was the grain transportation army sent by Wanxiu City, and there was the seal of Wanxiu City Guard.

The commander was completely relieved, and he waved his hand and smiled and ordered: "Kaejo!" ”

The gates squeak and quack! The ground pulled away, Wang Siyu's eyes slowly narrowed, and he ordered in a deep voice: "Don't panic, go in slowly." ”

Hundreds of Tibetan soldiers carried the steps up, and there was a team of women behind them, but the sky was dark, and they couldn't see their faces clearly, only to see them dressed in bright long groups, one step and three shakes, and entered the city gate beautifully, the Tubo army in the city was very happy, no one cared about the materials sent, everyone swarmed up, surrounded this group of beauties they had been longing for, but when they got closer, they found that this group of women were all tall, and seemed to be a few more burly than them, tall and tall, and all of them had flat chests, how could there be any women's curves, Looking at their faces again, they all have thick eyebrows and sunken eyes, grinning and smiling, many of them are still covered with rough bumps on their faces, and even a thick layer of fat powder can't cover them up.

"What the hell, how do you look like a man." A Tibetan soldier couldn't help but curse.

"That's right, Lao Tzu is a man, kill me!" Dozens of 'women' suddenly burst out with a loud roar, and two long knives appeared in their hands as if they were juggling, and slashed at the head of the Tubo army, cutting down dozens of people in an instant, and hundreds of 'Tubo soldiers' who were carrying the burden also drew their weapons from their burdens and rushed to the control of the city gate.

The sudden change stunned the Tibetan defenders in the city, and the commander saw that they all had a white belt on their arms, and he suddenly understood that this was the Tang army's deception of the city, he was shocked and frightened, and shouted and ordered his subordinates to rush up and seize the city gate.

But it seems to be too late, thousands of Tang troops have swarmed in, an unusually tall Tang army general holding a big iron gun, flying left and right in the Tubo army group, the cold tip of the gun is like a ghost judge in the hand of the pen in the hand, the gun killed, in a moment, there are hundreds of corpses around him, and everyone is shot in the throat and heart, the surrounding Tubo army is frightened, shouted, turned around and fled, Wang Siyu looked up to the sky and laughed wildly, his eyes narrowed, and his sharp gaze pierced the commander of the Tubo army.

The commander was also inspired by his arrogance, he roared, and swung his knife at Wang Siyu, but he froze only halfway, and he looked at him incredulously, a big iron spear had pierced through his chest.

Wang Siyu smiled coldly, raised the corpse of the Tubo commander high with a single gun, and shouted loudly: "The leader of the enemy army has been killed by me, brothers, the time has come to reward meritorious service!" ”

"Kill!" The blood of the Tang army was completely stimulated, they brandished their swords, and sacrificed their lives to kill in the depths of the castle for half an hour, the stone fort city changed hands, the Tubo army in the city was killed, the city gate opened, and several fast horses galloped eastward.

Night gradually fell, Ma Chongying led the army has chased more than 100 miles, he chased to a pool of lake water, then temporarily stopped the pursuit, ordered the soldiers to take water to rest, and waited for the rear brigade to follow.

With the passage of time, Ma Chongying's excited heart gradually calmed down, it was obvious that Zhang Huan already knew that the back road was cut off, so he retreated from the south instead, he had been in Hehuang for a long time, and he also knew that there were countless old roads leading to Longyou from the south, if Zampu's army still intercepted Zhang Huan in the area of the north city, it was very likely that he would escape.

Thinking of this, Ma Chongying immediately stood up and instructed a personal soldier: "You quickly take a few people to inform the intercepting army in the north, tell them that the Tang army wants to escape from the line of Ningsai and Anxiang in the south, and let them quickly go south to intercept it." ”

The soldiers received the order, rode away on horseback, Ma Chongying also turned over on his horse, looked at the east from afar, there are many rivers in this area, the fog in the air is very heavy, the smoke is filled all around, through the fog, the towering Chiling on the right is faintly visible, the left is the narrow Suihe Ridge, they have entered the knight valley, this is a trumpet-shaped valley, the west is wide and the east is narrow, more than 20 miles long, the widest part is about five miles, the narrowest part of the eastern valley mouth is less than 100 zhang, and it is there that the Tang people have built a castle, called Suihe Fort.

Ma Chongying has experienced a hundred battles, and he has always been careful with this kind of terrain, so he immediately ordered: "Send more scouts to the front to inspect, don't be careless." ”

After waiting for a while, the Tubo army behind arrived one after another, Ma Chongying looked up at the sky, the crescent moon was like a hook, the night was deep, he pointed to the front with a whip, "Let's go!" ”
