Outside the city of Pyongyang, a team of cavalry quietly sneaked out of the city, preparing to bypass the Tang army camp due west, so that they could report to Quangai Suwen at the mouth of Bogoukou, after all, not long after Quangai Suwen left Pyongyang, the Tang army outside the city suddenly killed, which made Quan's boy also immediately close the city gate, and then immediately sent someone to report to his father, because he was afraid of being intercepted by the Tang army on the road, so he sent a team of people to report the news almost every day.

However, the Tang army naturally would not sit idly by and watch the people in Pyongyang send people to ask for help, so they have been intercepting continuously in the past two days, for example, today this cavalry has just sneaked out of the city, and was discovered by the patrolling Tang army, as a result, a cavalry galloped out of the Tang army camp and quickly intercepted the team that reported the news.

The intercepted Goguryeo cavalry was also prepared, just when the Tang army intercepted them, this group of dozens of cavalry suddenly scattered and fled, running in any direction, although the Tang army also immediately dispersed to pursue, but there will always be a few fish that slipped through the net, and these people all carried the paperwork of reporting the news, as long as one of them could reach the mouth of the ditch, it would be considered a success.

Every time a team was sent to report the news, the boy would stand at the head of the city and watch nervously, and most of the teams that reported the news would be completely wiped out by the Tang army, after all, the cavalry of the Tang army was not only elite, but also the horses, much faster than their Goguryeo horses, so few people who reported the news could escape the pursuit of the Tang army.

However, today it was very successful, at least in the observation of Quan boy, there were five cavalrymen who reported that they had escaped the pursuit of the Tang army, but it was still unknown whether they could reach Bogoukou, after all, there were not only interceptions by the Tang army along the way, but there may also be other dangers.

Seeing that the person who reported the news escaped the pursuit of the Tang army, and finally disappeared on the horizon, and the cavalry of the Tang army who went to chase and kill also slowly returned to the camp, which made Quan Nan couldn't help but breathe a sigh of relief, after all, although the Tang army was elite, there were not many of them, only about 10,000 people, and they couldn't even surround Pyongyang City, so they could only send a patrol team, which gave him the opportunity to send people out of the city.

However, although the Tang army has few people, there are fewer defenders in Pyongyang City, and they are all pieced together, so that they can defend the city, and going out of the city is simply sending them to death, so the spring boy has been closing the city gate, but in this way, the materials in the city cannot be transported to Bogoukou, which is also the reason why he desperately sent people to report to the outside world, after all, without the support of Pyongyang City, God knows how long Bogoukou can be supported?

Thinking of the situation he is facing now, Quan Nannan can't help but feel anxious, this suddenly killed Tang Army cavalry, completely disrupted his and his father's plan, the materials that should have been transported to Pyongyang could not be transported, and even if Bogoukou was lost, he could no longer escape to Marudu City, it can be said that this cavalry had dragged him to death in Pyongyang City.

Now the biggest hope of the spring boy is that his father on the side of Bogoukou can receive the news, and it is best that the Tang army has not yet arrived at Bogoukou, so that his father can lead the army back and work with himself to destroy this Tang cavalry, so that he can continue the original plan.

However, Quan Nannan didn't notice that when he was standing at the head of the city and observing the situation outside the city, someone was also looking at him on a lookout platform in the Tang army camp outside the city, and this person was Su Dingfang, the main general of the Tang army

"Sir, according to your orders, the brothers deliberately let a few more go, which should guarantee that the Bogoukou side will receive the news!" At this moment, I saw Pei Xingjian ascending the lookout platform and reporting to Su Dingfang, who was holding a telescope.

"I saw it all just now, the brothers are doing well, give them more food in the evening!" Su Dingfang also slapped the railing at this time and said with a smile, if they hadn't deliberately released the water just now, none of those Goguryeo people would have escaped.

Before Su Dingfang landed on the west coast of Pyongyang, and then led the cavalry to Pyongyang City, but he didn't expect the city to be empty, at first he was a little strange, and then caught some surrounding Goguryeo people to ask, only to know that as early as a few days ago, Quangai Suwen actually led a large army to the direction of Bogoukou.

After learning the news that Quangai Suwen left with a large army and that the troops in Pyongyang were empty, Su Dingfang was also ecstatic at first, and even had an urge to take the opportunity to take Pyongyang City, but he soon calmed down, because he thought that he was full of cavalry in his hands, and he was not good at attacking the city at all, and even if Pyongyang City was empty, it was guarded by tens of thousands of people, and with this amount of troops in his hands, I was afraid that even if he could defeat it, he would suffer extremely serious losses, so in the end he changed his mind and began to guard outside Pyongyang. Cut off the city from the outside world.

However, some time ago, Quan boy kept sending people to break through, and at the beginning Su Dingfang also gave a death order, no matter what, he didn't let one go coldly, but then he suddenly figured it out, if Quan Gai Suwen at Bogoukou knew the news that Pyongyang City was besieged, he would definitely panic, and then he would create an opportunity for the main force of the Tang Army, so he deliberately let his cavalry release water.

"There is one more thing, please take a look at it!" At this moment, I suddenly saw Pei Xingjian speak again, and while speaking, he took out a bamboo tube from his sleeve and presented it to Su Dingfangdao.

"What is this?" Su Dingfang couldn't help but ask with a surprised expression when he saw this bamboo tube.

"Hehe, everyone's attention was attracted by those Goguryeo cavalry who reported the news just now, but our patrol team on the other side encountered a strange thing, that is, someone in the city quietly shot an arrow without an arrow at them, and this bamboo tube was tied to it, I think someone in the city wanted to report to us." Pei Xingjian smiled again at this time, he had just gotten this bamboo tube, and he hadn't had time to open it.

Quangai Suwen killed the King of Rongliu, but also left endless hidden dangers inside, it can be said that the Tang Army attacked all the way, there have been people who have been reporting to the Tang Army, many of them are loyal to the old department of the King Rongliu, and some people are seeing the strength of the Tang Army, and they choose to take refuge in the Tang Dynasty in despair, in exchange for future glory and wealth.

Hearing that this was information sent by someone in the city, Su Dingfang's eyes couldn't help but light up, and he took the bamboo tube and opened it at the moment, and sure enough, he pulled out a piece of information from it, but when he saw the content of the information, he couldn't help but look up to the sky and laugh and said: "God help me Datang, it turns out that Quangai Suwen didn't take too many supplies with him when he left, and all the materials that were supposed to be transported to Bogoukou were blocked by us in the city!" ”

Pei Xingjian couldn't help but show a look of ecstasy when he heard the above news, if Quangai Suwen lacked supplies, then it was almost certain that Bogoukou would not be able to hold it for long at all, not to mention anything else, this matter alone was enough for them to make a great achievement.
