After Li Yong took over the military order, he took all the guards and generals and began to inspect the entire Songzhou City, looking at the Tubo civilians who were driven out of their homes, Li Yong did not pay too much attention, after all, at this moment, these people staying in the city is a burden, maybe there are still a lot of Tubo fine works, when the time comes, the matter will be a big deal, he does not have this time to screen now, he can only make this decision, as for those Han people were told that they were very cooperative and left in a hurry, the gentleman does not stand under the dangerous wall, everyone understands, They didn't run out before, they were suddenly locked in after the incident, and now they can finally leave the place where this is wrong, so don't hurry up, the four city gates were closed by Li Yong two, one was used as an evacuation of civilians, and one was used as a transport of materials into the city, Li Yong walked up to the city and looked ahead and thought about it, the letter for help has been sent, but when the reinforcements will arrive, who doesn't know, but the army of Tubo is not far from here, and it is estimated that it will be about ten days to arrive, and the black army is pinned down again, Li Yong felt that it was really a lot of pressure to hold Songzhou. Xue Rengui, who was pinned, stared at the Tubo camp in the distance, and he was speechless about this army, it was like a dog skin plaster, the purpose was obvious, that is, to drag him and the black army and prevent him from supporting Songzhou.

"Save ammunition, it seems that Songzhou can only look at the commander himself, damn it~"

Xue Rengui felt that he was very embarrassed, the other party actually used an army of 100,000 to contain himself, and only confronted himself and did not attack, Xue Rengui also tried to take the initiative to attack, but these people learned to be obedient, as long as he attacked, they would withdraw, as soon as Xue Rengui withdrew, they would press, Xue Rengui's mentality was about to be blown up by them, what he knew was that this army was personally commanded by Lu Dongzan, Lu Dongzan's resourcefulness and military command ability, the current Xue Rengui is not an opponent at all, the so-called famous general, then continue to accumulate experience from the war, They are more gifted than others to grasp and apply these experiences, and it takes time.

"Six hundred miles urgently, hurry up and let it hurry~"

The knight with a small flag in Chang'an City rode his horse and galloped on Chang'an Street, and all the pedestrians on the road gave way to the passage, and the knight shouted all the way to the direction of the palace, and after he handed the letter in the mailbox to the receiving general, he fainted weakly.

"Quick, send it for treatment, I'll send it to the saint."

The two guards hurriedly helped the fainted knight to find Lang Zhong, and the general looked at the six-hundred-mile urgent letter in his hand, which was stained with three feathers and sealed with lacquer, and he put the letter in his arms, and then walked out of the palace.

"What are you looking for me?"

"My lord, this is a six-hundred-mile urgent letter from Songzhou, and I have detained it according to my wishes."

The general took out the six-hundred-mile urgent letter in his arms and handed it to him, and the man took it, opened the envelope without caring about anything, and quickly read the contents of the letter.

"You clean up, tomorrow I will arrange for someone to send you and your family out of the city, and I will fulfill the promise I gave you at the beginning."

"Master Xie."

After the general left, the man handed the letter to his henchman.

"It's burned, after that man leaves the city, he knows what to do, right?"

"The head of the family can rest assured, and his subordinates understand."

After the servant who had taken the letter had left the room, the man stood up and walked out of the door, looked in the direction of the palace and said.

"Li Shimin, do you want Songzhou? Let your army of 50,000 be buried with your good son-in-law. ”

No one knew what happened, the knight who sent the letter and the guards on duty that day saw that they knew about it and no one killed it overnight, this letter of urgent help for six hundred miles in Songzhou disappeared, no one in the court knew that Songzhou City was in an emergency thousands of miles away, Li Yong of Songzhou City They didn't know it even more, he dispatched everything day and night, the civilians in the city had all been driven away, the huge Songzhou City was already a military fortress, twenty giant catapults were placed in the direction of each city gate, and Li Yongxin stopped the throwing car on the city wall. In fact, it is a small catapult, this kind of throwing car has four wheels, a single wood in the middle, one end of the wood has a mortar used to hold the stone, when launching, the person presses the other end of the wood hard, the stone will be thrown, the effective distance is only three hundred steps (about five hundred meters), and the attack power is very good, mainly the operation is very simple. Li Yong also mixed hay and wet grass together to wrap stones, and then poured fire oil, the effect of the experiment was good, not only can attack and smash people, but also because of the wet grass, it will produce thick smoke, so it is a simple smoke cover, a cavalry of 5,000 people with enough dry food to hide outside the city, and after the arrival of the Tubo army, wait for the opportunity to sneak attack the rear of the opponent, a large number of stones and dry and wet grass are sent into the city, and then made into smoke stones. And the 100,000 troops of Tubo, under the leadership of Dazha, slaughtered Songzhou.

"How long will it take for us to get to Songzhou?"

"Tell the marshal, it will take three days to arrive."

"Okay, speed up, dare to steal my Tubo Songzhou, you must make those Tang people pay the price."

And Emperor Li Er in the Ganlu Hall didn't know what was happening, Duan Zhixuan's army had not followed since the last military report said that it had successfully arrived in Songzhou, it had been more than a month, whether it was lost or won, no one knew, and the ministers of the court could only comfort him, it may be that the war was tense or the road was far away so that he did not return in time, Li Er also silently prayed that nothing would happen, he made such a big move before sending troops to capture Songzhou, in case something happened, it was a problem that his good son-in-law was gone, His prestige must have suffered a huge blow, after all, many people did not approve and were optimistic about this expedition, and his pressure on the DPRK was increasing day by day.

"It's strange, why has it been so long since the letter asking for help was sent, why didn't the saint and the court reply at all?"

"That's right, if you rush six hundred miles, you should have arrived in Chang'an a long time ago."

Li Yong is also trying to find a problem, in this situation, it is impossible for Li Er and the imperial court not to react at all, is there something wrong on the way?

"No, I have to write another urgent report back, now we have only 30,000 combat troops, and the pressure is too great to hold the 100,000 army in Tubo, General Niu, please write another 600 li urgent letter to Chang'an, otherwise it will be too late."

"Okay."

Niu Jinda led the order to turn around and go out to write a letter for help again, and then the messenger ran in the direction of Chang'an without stopping, but this letter for help sank into the sea like the previous one, the reinforcements did not wait, Dazha's army was waiting, Li Yong and Duan Zhixuan They looked at the dense Tubo army in the distance outside the city, with flags covering the sun, they all frowned, they are all veterans who have experienced a hundred battles, Li Yong has also fought Tuyuhun and Turkic, this kind of scene has also seen a lot, but he is a sneak attack to hit the other party, with advanced weapons and equipment to crush the other party, Now you can only passively be beaten defensively, not to mention weapons and equipment, Li Yong hugged his fists and Duan Zhixuan said.

"General, we have sent two letters of request for help to the imperial court, both of which have been lost in the sea, there must be something wrong in the middle, the letter for help still has to be sent, and it can be sent out while it can still be sent now."

"Okay, I'll send it again right away, and now we can only face this 100,000 army first."

Dazha outside the city proudly took his generals to look at Songzhou City in the distance, holding a horse whip in his hand and pointing at Songzhou City and said domineeringly.

"Just them, the Tang army, dare to provoke our Tubo Divine Army, General Wunon, you lead 20,000 horses to try them first."

"Command, you can take a good look at it, and a certain general will lead the troops to take down Songzhou City."

This tall and tall Tubo will ride a horse and go to order troops in the future, and after a while, 20,000 soldiers will break away from the 100,000 army, and Li Yong and they will also see the changes on the Tubo side.

"I saw that Dazha wanted to try our details, the general asked you to go back to the Chinese army to sit in town, and I will leave it to the boy here."

"Okay, it's up to you."

Duan Zhixuan took his soldiers down the city wall and returned to the city to sit in the town, and handed over the task of defense to Li Yong, who said to several veteran generals.

"Uncles and uncles, the remaining three doors will be handed over to you, without my order, don't expose our hole cards, now the Tubo people are only attacking this side, just want to try us, we only have 30,000 defenders, we must not be careless, we must preserve our strength."

"Command."

Those generals clenched their fists and ordered them to go down the city wall and rush to the gate they defended, and Li Yong took Li Tiezhu and other guards to command.

"Brothers, don't be afraid, put these Tubo dogs close and fight again, let them know that we are powerful, steady, don't rush, steady."

All the soldiers hiding in the battlements of the city wall are slowly adjusting their breathing, they are all veterans, and they do not feel timidity and fear like the recruits, but more of the excitement of excessive adrenal hormone secretion, Wu Yan took his 20,000 Tubo troops in a line, and walked forward with contempt for the Tang army in the city, and even walked over while waving the scimitar in his hand and shouting arrogantly, Li Yong looked at these brainless Tubo soldiers, and secretly cursed a group of fools in his heart, slowly, the Tubo soldiers under the city have entered the range of bows and arrows, But Li Yong still did not give the order to attack, which made Wu Yan and his soldiers even more rampant, carrying the rough ladder and swaggering towards the city wall, when half of them had passed the marked range, Li Yong picked up a longbow and drew the bow to shoot down, shouting.

"Put~"

Li Yong has never learned archery, but there are so many people below, the blind can shoot, the soldiers who received the order to release arrows instantly stood up from the battlements of the city wall, "boom ~ boom ~ " A rain of arrows shot towards the Tubo army under the city like a dark cloud, and those arrogant Tubo soldiers were immediately shot on their backs, but they were too arrogant, from the beginning they all walked forward, and now it was too late to run, and the rain of arrows on the city wall suppressed them.

"Don't panic, resist, resist, the archers fight back~"

But how did they withstand it, the rain of arrows on the city wall shot at them like leeches, and the archers who wanted to fight back couldn't shoot the Tang army on the middle and tall city walls, Li Yong applied the three shots of the musket to the archers, and the soldiers who finished shooting squatted down and hid in the battlements of the city wall, and the other stood up to shoot, so that the physical strength of the archers could be preserved and the archers could be effectively protected. Dazha saw that the tempting army was resisted to the death for nearly half an hour, and he couldn't see the details of the Tang army, so he asked Ming Jin to withdraw his troops.

"Ten miles back and set up camp, and build siege equipment overnight."

Hearing the golden sound of the troops, Wu Yan had no choice but to retreat with the remaining soldiers, Li Yong saw that the Tubo army had retreated, so he asked everyone to stop attacking, knowing that today is a small test, and tomorrow will be the real battle.

"Weapons were checked, supplies were counted, and the wounded were sent to the rear army for medical treatment."

Several unlucky envoys who were shot in the arm by the Tibetan archers were sent off the city wall, Wu Lun retreated to the army and knelt down to Dazha to plead guilty, Dazha also unceremoniously whipped him ten whips, saying that he underestimated the enemy carelessly, lost so many brave soldiers, Wu Lun also realized that he did underestimate the enemy, he hated the Songzhou guards to death, he had never tasted such a defeat since following Lu Dongzan to the south and the north, he secretly swore that when the city was broken, he would kill all the Tang troops in the city to wash away today's shame, after the armistice between the two sides, Tubo sent people to pull back the corpses of the soldiers who died under the city wall, this was tacitly agreed by both sides on the battlefield, Li Yong sat under the battlements of the city wall, took the dry food handed to him by the iron pillar, Li Yong took a bite and almost choked to death.

"Damn, this steamed bun is really dry."

Now in this environment, Li Yong didn't have to choose, he was gnawing on the dry steamed buns, while thinking about the logistics of the black army, compressing the biscuits, he wanted to eat this thing for the first time, Li Yong and all the soldiers finished dinner, and began to look at the busy Tubo camp in the distance, Li Yong knew that they were building tomorrow's siege equipment, thinking that tomorrow must be a big battle.

"Give the order to go down, rest in shifts, and always pay attention to the Tibetan camp to prevent night attacks."

The herald received the order and ran down the city wall and other city gates to give the order, Dazha, who originally wanted to attack at night, saw the tight defense of Songzhou City, so he gave up this idea, and the next morning, a piercing horn like a horn broke the silence of the whole Songzhou, Li Yong watched the soldiers of the Tubo battalion continue to line up and get ready to go, and the city walls of the four city gates immediately entered the preparations, because they found that the entire Songzhou City had been surrounded by water.

"Be ready for battle, and let those Tibetans know how powerful we are."

The Tang army on the city wall clenched the longbow in their hands, and the sword had been put on the bowstring, just waiting for the Tibetan army to attack, Dazha began to give orders to his generals, with the drums that began to attack, and sent orders to all the Tubo soldiers outside Songzhou City, the siege vehicles, and the cloud ladder marched like Songzhou City under the impetus of the Tubo soldiers, Li Yong and all the generals and soldiers nervously looked at the Tubo army below like ants, and as they got closer and closer to the city wall, the Tubo generals shouted one after another.

"Charge~"

"Kill~"

The Tubo army began to attack Songzhou City, and instantly crossed the range of throwing the car, and Li Yong gave the order without hesitation.

"Throwing a car projection."

The throwing cart hidden on the city wall was pushed out, and the stones wrapped in dry grass and wet grass were put into the mortar, and then poured fire oil, pressed hard, and threw stones with fire into the Tubo army, and the soldiers who were smashed were killed instantly, and the remaining three city walls also began to use the throwing cart to the enemy, after those burning stones killed people, the flames slowly extinguished, and smoke began to rise on the battlefield, obscuring the sight of the Tubo army, but the Tang army on the city wall did not need to think about this problem, Because there are dense Tubo soldiers below, it is okay to shoot arrows and throw stones to death, Li Yong saw that the smoke was already billowing below, so he ordered to change the stones to throw, Dazha was also confused by this thing that would emit smoke, worried about fraud, and ordered the army to retreat, the Tubo army received the order to retreat, and began to cover his nose and cough and retreat, Dazha looked at his soldiers who were smoked by the tears and snot flowed out, knowing the means of the Tang army, and when the smoke on the battlefield dissipated, Dazha ordered to attack again, And Li Yong's side is the old routine, back and forth so that Dazha is helpless, had to Mingjin to withdraw the troops, after seeing the Tubo retreat, Li Yong and all the people breathed a sigh of relief, but the situation is not as optimistic as he thought, there are many soldiers who were killed and injured by the archers of Tubo, after all, the Tubo people are also nomads, and they are still very good at riding and shooting, although the loss is still within the acceptable range, but after all, the other party has 100,000 people, he can't afford it here, and the bows and arrows and stones guarding the city will definitely be consumed, Li Yong called Li Tiezhu.

"I'll write you a letter later, you rush back to Chang'an at night tonight, personally hand it over to the old bachelor, and let him hand it over to Du Ruhui and Du Xiang, whether we can hold Songzhou depends on you."

Li Tiezhu took the letter written by Li Yong, looked at Li Yong with a heavy heart, and then left the barracks without looking back, and ran towards Chang'an under the cover of night, Li Yong vaguely guessed that there must be something wrong with their letter for help, what it was, he didn't know, all this had to wait until he could go back alive, Li Yong found Duan Zhixuan late at night.

"General, I'm sorry to disturb your rest so well."

"Don't be polite to me, the 100,000 army of Tubo outside the city, where am I sleeping now, I played well today, by the way, what are you looking for me so late?"

Li Yong looked at the haggard Duan Zhixuan, and his heart was also heartbroken, but now it is estimated that the entire Songzhou City is like this.

"General, I'd like to have some fun with Daza tonight."

"Oh? What do you want? ”

"I think that today Dazha and they will be smoked for a day, and it must be uncomfortable, so I want to concentrate all the big drums in the army, and then let some sergeants shout while beating the drums, so that Dazha thinks that we are out of the city to steal the camp and disturb his military spirit."

Duan Zhixuan thought for a while and said.

"Okay, do as you say, your kid's is really poisonous, Dazha definitely didn't sleep well tonight."

Li Yong immediately went out to arrange it, and sure enough, Na Dazha had already been stolen by the Tang army to steal the camp, and immediately gathered the army, but it was dark in front of him, what was the shadow of the Tang army, and the Tubo soldiers who had been smoked by the Tang army for a day today were uncomfortable, and they were even more uncomfortable by this, and after an hour, Li Yong let the drum beat again, and people shouted, of course, Dazha and his army were not frightened to gather again, which made Dazha angry.

"Wait and do it again, it's kind of for Dazar and his soldiers to get up and pull the night pee, and then we'll rest."

Dazha and his soldiers stayed awake all night, when they got up in the morning, they all yawned with panda eyes, and they naturally couldn't capture Songzhou City in this state, and they made no progress for a whole day, Li Yong and they held Songzhou for another day, and Li Tiezhu, who reported to Chang'an all the way, traveled day and night, eating on the horse when he was hungry, sleeping on the horse when he was resting, the horse was not good, and he immediately spent money to buy a horse, anyway, he wanted to rush back to Chang'an in the shortest time, Xue Rengui was also anxious here, because the ghost had already told him about the situation in Songzhou, But Li Yong ordered him to keep an eye on this army and not let them support it. Li Yong no longer knows how many times he has repelled the attacks of Tubo, and the bow and arrow are basically damaged, and the craftsmen can't repair and replenish them, but the Tubo army is still as dead as ever.

"Damn, the catapult starts attacking~"

"Buzz~Buzz~" A loud sound of the catapult being opened the rope, a fast boulder flew over the city wall like a meteor and smashed it outward, when the Tubo soldiers outside saw a black shadow, it was too late to dodge, a boulder fell down and brought a large number of Tubo soldiers, Dazha saw that the Tang army was still such a weapon of mass destruction, and quickly let the soldiers who rushed up retreat, Li Yong looked at the Tubo soldiers who were receding like a tide, he sat down weakly, his hands trembled and he couldn't hold the long knife in his hand, A soldier who lost his life was carried down in front of him, today is the tenth day of his defense of Songzhou, the bow and arrow are basically used up, and the car is also damaged more than half, every day the soldiers of Tubo can rush to the city, Li Yong took the lead and drove back the Tubo soldiers who jumped on the city, the rear army camp is already full of wounded soldiers, and there are about 10,000 soldiers left who can fight, Duan Zhixuan and Niu Jinda both took their own soldiers to the city wall to fight, Li Yong was injured in many places, Li Yong breathed a sigh of relief, Trembling and holding on to the city wall, he looked at the corpses of the dead soldiers below, his heart was not a taste, and the soldiers were demolishing the houses in the city to replenish the stones, Li Yong didn't know how long he and the soldiers here could hold on, in ten days, he lost more than 10,000 Tang soldiers, in order to prevent the plague, he had to burn the corpses of thousands of Tang soldiers every day, the whole Songzhou blood flowed like a river, death was everywhere, and the whole Songzhou City was too miserable.
