"Ready to shoot!" A Lang general raised his voice, and the two thousand crossbow soldiers raised their crossbows on the ground and aimed at each other coldly.

The Tibetan cavalry also raised their shields one after another, holding short spears in their hands, and increased their speed, like a flood bursting the embankment, rushing towards the valley mouth, and gradually approaching the valley mouth.

The heavy crossbow army on the castle was the first to launch, their heavy crossbow had a long range, a thousand big arrows shot to the sky in a parabola, and fell from the sky like hail, the Tibetan soldiers raised their shields to resist, but their shields still could not block the strong power of the heavy crossbows, the shields were shot through, more than 100 soldiers were shot by arrows, rolled down from the horses, and were instantly swallowed by the torrent of rolling iron horses.

A round of heavy crossbow fire did not deal a major blow to the Tibetan army, which was instantly killed two hundred paces away.

The sound of bangzi sounded suddenly, the first row of two thousand crossbow troops fired, and the dense arrows shot at the cavalry of the Tubo army like a storm, the cavalry held a shield and hid behind the war horse, and the war horse in front fell down with arrows, throwing the cavalry out, and many cavalry did not have time to get up, so they were knocked over by the war horse behind, trampled by the horse, and the flesh and blood were blurred.

The Tibetan cavalry was too close to use vertical shooting, so they could only use flat fire, but the killing range of flat fire would be greatly reduced, and the Tibetan cavalry in front became the natural meat shield of the cavalry behind.

However, the Tang army also used sectional shooting, the first row of shooting ended, followed by the second row of fire, and then the third row and the fourth row of fire, round after round of arrows were fired, the arrows were dense like rain, the Tubo cavalry continued to fall from horses, and the casualties gradually increased, and the casualties of only two rounds of arrows amounted to more than 800 people.

At this time, thousands of Tibetan cavalry had already rushed to sixty paces away, and the hideous faces of the Tibetan soldiers could already be clearly seen.

"The crossbowmen retreat, the Mo Dao Army!"

The drum sounded, and the two thousand crossbowmen quickly retreated, revealing the tall and mighty heavy armored soldiers behind them, like an iron wall, the heavy armored infantry brushed the Mo knife out of the ground, coldly forming a knife forest, in order to meet the impact of the enemy cavalry, the heavy armored infantry has changed the formation, the front row of soldiers knelt on the ground on one knee, held the knife shaft with both hands, and pressed the tail of the knife shaft to the ground, and the sharp Mo knife was at a 45-degree oblique angle upward.

The cavalry will directly hit the sharp blade, and the powerful impact force will eventually be transmitted to the ground, and the rear row of heavy infantry will also be half-kneeling, the sharp Mo knives are facing upward, and the two rows of Mo knives form a cold and shining knife forest.

Thousands of cavalry rushed like a gallop, the Tang Dynasty's Mo Dao Army has disappeared for more than 20 years, when it reappeared, most of the Tubo cavalry had not seen it, when they rushed close to the knife forest, they suddenly found that the front was a cold and shining long knife, it was impossible to retreat, and thousands of troops and horses behind were pushing them forward.

In an instant, they rushed to the front of the Mo Dao array, the Tubo soldiers screamed miserably, closed their eyes, the front hooves of their war horses were raised high, but the cavalry behind them directly knocked them into the sword forest, and suddenly blood spurted, blood mist was filled, and the air was suddenly filled with a bloody breath that was difficult to breathe.

After a series of collisions killed hundreds of people, the cavalry finally stopped, Kang Bao roared, and a thousand Mo Dao soldiers Huo Di stood up and began to wield Mo Dao to kill the enemy cavalry step by step.

Long knives flew all over the sky, limbs flew sideways everywhere they passed, human heads rolled, war horses and human limbs were mixed together, extremely bloody, and the Tibetan lord general Ronlituo shouted anxiously in the back: "Rush away from the enemy!" Rush out! ”

But no matter how he shouted, the Tubo cavalry could not break through the Tang army's Modao battle line, and the war horses were also frightened and screamed.

The Tang army's Mo sword army was as cold as iron, and they advanced step by step, and the Tubo soldiers were cut down piece by piece like wheat.

Overhead, the Tang army's heavy crossbow arrows whistled and fired, making it difficult for the Tubo army to resist.

The casualties of the Tubo army were getting bigger and bigger, the casualties were nearly half, and the morale gradually collapsed, and a commander of five hundred people shouted urgently: "General, the casualties are too great, retreat!" ”

There was nothing to be done about Lituo, so he had to give a long sigh and order: "Retreat!" ”

The Tubo army retreated like a tide, and the fighters appeared, and Guo Song coldly ordered: "Cavalry attack!" ”

Outside the valley mouth, the five thousand cavalry had already finished marching, the red flag was waving on the Tuniu Fort, and the horn of the Tang cavalry suddenly sounded, 'Woo-'

The soldiers of the Modao Army got out of the way one after another, standing on both sides of the valley, five thousand cavalry surged in, and chased into the Dadou Valley like a gallop, the Tubo army was not prepared to defend, the army was scattered, the morale was low, and the Tang cavalry was defeated and fled, and the Tang cavalry chased out thirty miles in one breath, and chased to an extremely narrow corner, which stopped the pursuit.

Of the 10,000 Tibetan troops, less than 3,000 people were left to flee with the main general, and the remaining 7,000 people were wiped out and corpses were strewn all over the place.

Guo Song led the army into the depths of the Great Dou Tu Valley, a mountain grassland more than ten miles wide in the Great Dou Ba Valley, the grassland stretches to the mountains on both sides, and then up is a large area of cedars, which can accommodate at least tens of thousands of people.

In early summer, the grasslands are particularly vibrant, full of all kinds of small flowers, purple and gorgeous, swaying in the wind, which is refreshing.

"Governor, this grassland is a good place, and it should be controlled by us." Yao Jin couldn't help but praise.

Guo Song nodded and said: "Not only that, the entire Great Dou Tu Gu should be controlled by us, the enemy army has been defeated, and the ability to control the Great Dou Tu Gu has been greatly weakened, I will hand over this task to you, and I will take the Da Dou Tu Gu within a month." ”

"Obey the order!"

Guo Song ordered the heavy infantry and crossbow infantry to follow Yao Jin to sweep through the Great Dou Tu Valley, and he himself returned to Zhangye with 3,000 cavalry.

As soon as Guo Song arrived in Zhangye, Pan Liao and Zhang Qianyi reported to him the latest news of the negotiations, and Shatuo Khan had just received the news, and at the same time, Guo Song put forward conditions to end the negotiations as soon as possible and exchange prisoners of war.

Guo Song pondered for a moment and said: "Add a clause to the negotiation conditions, if Shatuo does not attack Tingzhou City, the Ganzhou army promises not to attack Guazhou, and will also give up the alliance with Gelulu. ”

Pan Liao was really a little surprised, "Dudu, did Ge Lulu really send someone?" ”

Guo Song smiled and shook his head, "There is no such thing, just to scare and scare Sha Tuo, I believe that Sha Tuo is indeed very afraid that we will form an alliance with Qarlu, and the north and south will attack it, this is the condition of earning out of thin air." ”

Zhang Qianyi sighed, "No wonder Zhu Xie Jinman promised so easily, so the two sides can initialize the agreement tomorrow?" ”

"Yes, I'll have one last talk with him tomorrow, and if both sides confirm it, we can sign the agreement."

After a pause, Guo Song said again: "However, the news of the fierce battle between us and the Tubo army must be blocked, and the Shatuo people must not know about it, which is very important for us to recover Shazhou." ”

The three of them discussed for a while, and finally Guo Song felt that Zhang Qianyi should be sent as a special envoy to Sha Tuo for negotiations, and monitor Sha Tuo to deliver 300,000 sheep to Tingzhou.

.........

Early the next morning, in the hall of the Governor's Mansion, Guo Song personally finalized the final negotiation results with Shatuo's special envoy Zhu Xie Jinman.

There was a large table in the middle of the council hall, Guo Song and Sha Tuo Jinman sat opposite each other, on both sides were their deputies, the officials of the Governor's Mansion and Sha Tuo's entourage were sitting in the back, the atmosphere was serious and frank, and the negotiations reached the last moment, and the hole cards of both sides were opened, so many words were said on the open side, no longer subtle and obscure.

Zhu Xiejin was open and honest: "The biggest worry of our khan is whether the governor of Guo can represent the imperial court, I am afraid that today we have reached an agreement, and when we change the governor, we will not recognize it, so what is the point of negotiation?" ”

Guo Song smiled faintly, "It seems that you Khan didn't understand what the essence of this negotiation was?" This negotiation is just a continuation of the war, both sides speak with strength, if there is no Ge Lulu behind the back, I think there will be no negotiation at all, Sha Tuo will definitely pour troops to kill, the same, if it weren't for Tingzhou let me cast a mouse trap, I will directly lead the army to recover Guazhou and Shazhou, both sides have to have a last resort to sit down to talk, as for the results of the negotiations, in addition to the exchange of prisoners of war and the delivery of cattle and sheep, I think other promises will not be taken too seriously, when it is time to send troops, Sha Tuo is so, so are we. ”

Guo Song's frankness made Zhu Xie Jinman a little difficult to accept, and he was silent for a long time and said: "What does Guo Dudu mean is that the Tang army will still join forces with Ge Lulu?" ”

Guo Song shook his head and said: "It's just my personal attitude, as long as Sha Tuo doesn't embarrass Tingzhou, I, Guo Song, will not consider joining forces with Ge Lulu, as for whether the imperial court will reach some kind of agreement with Ge Lulu, I'm not sure, but as long as I, Guo Song, am still in Ganzhou one day, I have to consider the safety of Tingzhou, which you should know in your hearts." ”

Zhu Xie Jinman sighed and said: "Since Guo Dudu is willing to hand over 300,000 sheep to Tingzhou, we know that Guo Dudu really cares about Tingzhou, and I am afraid that your court and Ge Lulu will reach some kind of compromise!" ”

Guo Song smiled and said: "The Tang Dynasty has a deep feud with Ge Lulu, it is not so easy to unravel, in fact, the imperial court will not have any connection with Ge Lulu, you khans don't have to worry about this, at most, the ruler of Hexi will consider cooperating with Ge Lulu from the perspective of war, does Ye Hu understand what I mean?" ”

Guo Song made a detour and pointed out whether to cooperate with Ge Lulu, and the initiative was actually in the hands of Guo Song, and had nothing to do with the imperial court.

Zhu Xie Jinman finally understood, and he tentatively confirmed: "What does Governor Guo mean is that whether the Tang Army cooperates with Ge Lulu or not lies in the situation of Tingzhou? ”

"Exactly!" Guo Song admitted it calmly.

Zhu Xie Jinman nodded, "Okay! As Governor Guo said, our two sides are still in a state of war, both sides speak with strength, and we will first finalize the exchange of prisoners of war! ”

On the morning of the same day, the two sides reached an agreement on the exchange of prisoners of war, Shatuo would release 4,300 Tang prisoners of war and 11,000 captive Han Chinese, and another 300,000 sheep to Tingzhou, while Guo Song would release 6,400 Shatuo prisoners of war, as well as Zhu Xie Shenglu, who Shatuo was eager to exchange, and each side would send envoys to supervise whether the other party fulfilled the agreement.

As for the Tang army's occupation of Suzhou and whether it will continue to attack Guazhou, or even whether the Tang army will cooperate with Gelulu, there is no mention in this agreement, as Guo Song said, this negotiation is just a continuation of the war, and the follow-up development, both sides speak with strength.

Sha Tuo is in control of the life and death of Tingzhou, and similarly, the Tang army is also pinching Sha Tuo's weakness.
