Quangai Suwen was really as Su Dingfang guessed, and quickly saw Gaozang's flaws, but it was too late at this time, not only were arrows raining down on the city, but Su Dingfang also personally led 7,000 cavalry to rush over, and in the blink of an eye, they were killed in the army of Goguryeo, and for a while, the soldiers under Quangai Suwen were also in chaos.

Although Su Dingfang's cavalry was elite, it was impossible to enter the Goguryeo army so easily, but after coming to the city of Pyongyang, these Goguryeo soldiers all relaxed their vigilance.

As long as the cavalry of the Tang army charged, it was like a bulldozer in later generations, and Goguryeo, who could not react in front, was quickly overturned by the people they rushed on, and Quangai Suwen also reacted at this time, and hurriedly commanded his subordinates to counterattack, but the cavalry of the Tang army came and went like the wind, and did not stop at the same place at all, but rushed left and right in the Goguryeo army, and finally killed from the other side, causing the Goguryeo army to be cut into two sections.

"Kill~" But this is just the beginning, I saw Su Dingfang's cavalry rushing out and turning around, and then killed back like a dragon, but at this time, Quangai Suwen was also desperate, no matter what, he couldn't let the Tang army rush in again, so he immediately ordered: "Nanjian, lead the Five Swords Army to meet the enemy!" ”

The Five Swords Army is Quangai Suwen's personal guard, and he once gave a part to Gao Yanshou, but unfortunately he was wiped out on the battlefield by Li Daozong, but Quangai Suwen still has three thousand five swords by his side, which is also his biggest hole card, and he will never move lightly until the critical moment.

Quan Nanjian also agreed at the moment, and then led the Five Swords Army to meet him, and Quan Gai Suwen also began to gather other teams at this time, and then ordered them to assist Quan Nanjian in encircling the Tang army.

As the Five Swords Army joined the battle, Su Dingfang's cavalry finally met the opponent, and the offensive slowed down suddenly, although it was still advancing, but it was not as fierce as just now, and at this time, other Goguryeo troops also began to besiege, which made Su Dingfang's attack a little difficult.

However, Su Dingfang is a veteran of the battlefield, in the face of this unfavorable situation, he immediately changed his tactics, with his order, the entire cavalry immediately changed direction, first out of the battlefield, and then rushed towards the rear army of Quangai Suwen, which made Quangai Suwen also frightened in a cold sweat, and immediately shouted for people to intercept.

According to the habit of marching, the general food and materials are placed in the position of the Chinese army, and there are large armies guarding the front and rear, so as to prevent the enemy's sneak attack, but Quangai Suwen rushed back to Pyongyang this time, so he also traveled day and night, but the food and materials were too heavy, even if they were pulled by a car, they couldn't go fast, so they fell behind, and there were not many supplies this time, and in his mind, as long as he could return to Pyongyang, it was nothing to lose this little material.

But now that the city of Pyongyang has been occupied by the Tang Dynasty, the materials carried by the army have become extremely important, if Su Dingfang destroys their only materials at this time, then the Tang army will not have to fight at all, I am afraid that it will not take three days, and the army under his command will collapse.

Su Dingfang's cavalry was very fast, and he killed the rear army of Goguryeo in the blink of an eye, and at this time, although Quangai Suwen desperately urged his soldiers to defend, but he was still a step late, and as a result, he saw Su Dingfang rushing into the material convoy, talking about burning materials, Su Dingfang was simply too good, he had been doing this for a few years, so in the blink of an eye, Goguryeo's rear army was on fire.

However, Su Dingfang also failed to burn all the supplies, because the Goguryeo people in the back also arrived, and these Goguryeo people also knew the importance of the materials, so at this time, they were like crazy, desperately besieging the Tang army, which made Su Dingfang have to withdraw from the battlefield again, but then they were killed again, anyway, they were cavalry, and they left every time, although the casualties brought to the other party were not large, but they put huge pressure on the Goguryeo people.

"Father, it's not a way to go on like this, and Pyongyang City has been lost, and some of the supplies have been burned, if we continue to be entangled by the Tang Army like this, I'm afraid we won't be able to support it!" At this time, Quan Nanjian led the army back to Quan Gai Suwen's side, and then wiped the blood on his face.

Quan Gai Suwen's face was also extremely gloomy at this time, but he also made a quick decision, and ordered in a deep voice: "Order the whole army to retreat to Buyeo City immediately!" ”

"Buyeo City? What's the use of going there? Quan Nanjian couldn't help but be stunned when he heard his father's words, and then said a little incredulously.

Buyeo was originally a country in the Liaodong region, the capital was Buyeo City, near Jilin City in later generations, and was later destroyed, and the then Buyeo King fled to Goguryeo for help, but Goguryeo did not want to help Buyeo restore the country, but also annexed a lot of Buyeo land, as for the Buyeo king, they were placed in a small city not far northeast of Pyongyang, and the name of the town was changed to Buyeo City, which is not the same thing as Buyeo City on the Jilin side.

Although Buyeo City is the original place where the king of Buyeo lived, it is actually only a very small city, it used to be one of the acropolis of Pyongyang City, although the city wall is still strong, but the area is too small, at most only a few thousand people can be stationed, before Quan Gai Suwen desperately transferred the army, and also evacuated the troops of Buyeo City, it can be said that there are no soldiers there, and it is useless for them to go there with 50,000 people.

"No matter how bad Buyeo City is, there are walls to defend, and there are some materials stored in the city, as long as we get there, we can simply rest and recuperate, and then make long-term plans!" Quan Gai Suwen immediately spoke, he had said to Quan Boy before, if Bogou Kou could not be defended, let him retreat to Marudu City, and Buyeo City was the first stop to Marudu City, so some supplies were also prepared there.

Hearing his father say this, Quan Nanjian no longer hesitated at the moment, and immediately assisted his father in commanding the army to retreat to the northeast, but Su Dingfang was in hot pursuit, and from time to time there was a harassment battle, which made Quan Gai Suwen unable to retreat at full speed, and when the flaws were exposed, Su Dingfang would take a hard bite, making the losses of the Goguryeo army bigger and bigger.

This pursuit battle lasted for two days and two nights, and finally Quangai Suwen's army finally arrived at Buyeo City, originally from Pyongyang to Buyeo City only half a day's journey, but they took twice as much time, and Su Dingfang saw that the other party retreated to the city, so he was unwilling to stop, and then stationed outside the city, although their troops are not many, but they can drag Quangai Suwen can not retreat, and Su Dingfang is also very clear that Li Shimin's main army must be behind, as long as he drags on for a few more days, wait until the army in the rear arrives, Quangai Suwen didn't want to run away again.

In fact, when Su Dingfang blocked Quangai Suwen in Fuyu City, Li Daozong in the rear finally led 10,000 cavalry to Pyongyang City, Pei Xingjian immediately went out of the city to greet him, but when Li Daozong learned that Su Dingfang went to pursue Quangai Suwen, he didn't stop at all, and immediately led his troops to chase down, after all, Su Dingfang did not have many troops in his hands, and he was also worried that the other party would not be able to drag Quangai Suwen.

However, Su Dingfang wanted to drag Quan Gai Suwen, Quan Gai Suwen naturally knew his situation better than anyone else, and after he arrived in Buyeo City, he immediately thought clearly about his current situation, Pyongyang City has been lost, and Quan Nan and his family must have suffered accidents, but these don't matter, the key is that he is still alive, as long as he is alive, there is hope.

And Quan Gai Suwen thought that he still had 5,000 elite soldiers in Marudu City, which was originally reserved for Quan Boy to defend the city, but now Quan Boy was gone, so he had to rush to Pill City in person, as long as he got there, and then dragged the Tang Army until winter, it could bring a turn for the better in this war.

Of course, Quangai Suwen also knew that in addition to Su Dingfang's cavalry, the main force of the Tang army must be chasing after him, if the main force of the Tang army and the Tang cavalry outside the city converged, he would not have any chance to escape, so there was not much time left for him, and he had to rush to Marudu City as soon as possible.

It was with the above thoughts that Quangai Suwen only rested for one day in Fuyu City, and the next day he regrouped and went out of the city, and this time he made up his mind that he had to repel Su Dingfang no matter what, otherwise he would not be able to escape at all.

Su Dingfang saw that the other party was menacing, although his cavalry was elite, but after all, he did not have an advantage in numbers, so he retreated after a few contacts, and then used the old tactics before, that is, he stared at the opponent's tail and stepped forward from time to time to take a bite.

However, Quangai Su Wen also wanted to escape this time, seeing that Su Dingfang was planning again, he actually divided the army into two, of which 10,000 troops dragged Su Dingfang's army to death, so that the other party could not pursue it separately, and he led the rest of the army to flee in the direction of Marudu City, this trick is called breaking the tail to survive, as long as he can lead the troops to escape to Marudu City, then all the costs are worth it.

Su Dingfang didn't expect Quangai Suwen to be so decisive, and he was desperately trying to break through the enemy's encirclement at the moment, but the 10,000 people left behind were led by Quangai Suwen's henchmen, and they didn't plan to go back alive at all, so they were also desperate on the battlefield, even if they couldn't beat Su Dingfang's cavalry, they couldn't fight to the death, and Su Dingfang couldn't rush over for a while.

Seeing that Quangai Suwen was about to flee with a large army, and this was already the edge of the Pyongyang Plain, and beyond that were hills and mountains, if Quangai Suwen was allowed to escape into the mountains, with the advantage of their familiarity with the terrain, they would probably escape from the pursuit of the Tang army.

However, maybe God wants to let Quan Gai Suwen die here, just when his army was about to escape from Su Dingfang's sight, he suddenly saw another army suddenly appear in front of him, and intercepted Quangai Suwen at once!
