Basically, this old road started to go different from today's Puyang County, because the place where the Yellow River flowed at this time was dozens of miles south of this old road. It flows slightly easterly, and eventually enters the sea in Leling County, south of the Bohai Kingdom. However, compared to the Qinghe River, Zhangshui is still smaller. Whether in terms of water volume or river breadth, Qinghe is even better!

The direction of these two rivers is the same, the source of Qingshui is in Ji County, and in the north of Jianxing County, the horizontal distance between Zhangshui and Qinghe is still relatively far. However, at the beginning of Guangzong County, Jianxing County, the east-west distance between the two rivers was reduced to only more than 40 miles.

Moreover, from here to the south to Yecheng, the distance between the two rivers is almost this wide.

At such a little distance, as long as there is a city in the middle, it can firmly block the Tang army. Not to mention that a lot of soldiers and horses were placed outside the city, and obstacles were set up specifically to resist the southward movement of the Tang army.

Although it may not be possible to stop the Tang army in the end, if Peng Lin wants to fight all the way, the time it will take will inevitably become much more. Especially when Murong Ke had already ordered the soldiers and horses everywhere to delay the Tang army's southward movement as much as possible.

Jianxing County originally did not have this county, it was a county that Yan State cut and separated from other counties in this area from the original Western Jin Dynasty Shi Zhao and other dynasties after occupying the Central Plains, and recombined a county. This county is governed by Gwangjong County and is located on the west bank of the Qing River.

Guangzong County has been captured by Li Xin, and he has attacked all the way south, basically with the cooperation of oil, and has achieved good results. Often, as soon as a burst of fire attacked, the city gate basically burned down.

Coupled with the fact that there was no foothold on the city, the soldiers of the Yan army were terrified by this unquenchable fire, so it was naturally much easier to take these places.

However, Li Xin didn't want to use this tactic much, mainly after persuasion to surrender was fruitless, and the tentative siege found that it could not be captured quickly.

After receiving the news that Murong Ke was determined to move the capital to Guanggu, Li Xin stopped for the time being.

"Move the capital! This is a good move, if he can really do it, at least the danger of destroying the country can be alleviated! Looking at the news sent by the carrier pigeon in his hand, Li Xin groaned.

"The matter of moving the capital is extremely important, I'm afraid it can't be done in a hurry, right?" Tu Qi said on the side.

"Thinking about it now, I finally understand why Murong Ke was bent on fighting Jiang Zuo before!" Hearing this, Li Xin suddenly laughed.

"Oh? His Highness already knows his intentions? Deng Qiang said curiously.

"Not bad! I didn't understand it before, it was because I didn't expect it to be today, but obviously, Murong Ke thought of it. At this point, I have to say that Murong Xuangong is indeed powerful, and he began to arrange it early! Li Xin bowed his head slightly and said.

"What does Your Highness mean that Murong Ke attacked Jiangzuo in a big way before, but it was actually for the purpose of moving the capital?" Hong Yi reacted a little.

"Exactly! Murong Ke's idea should have been that Yecheng was not safe for a long time, so he wanted to move the capital to a safer place. Needless to say, Guanggu's place is much safer than Yecheng. But there is a problem, that is, although Guanggu City is far away from us, it is relatively close to Jiangzuo. Therefore, if you want to build Guanggu City into a safe and stable capital, as a place for Yan to protect itself, you must find a way to solve the threat to the south of Qingzhou. And this is exactly the reason why he advocated sending troops south despite the opposition of others! ”

"Listening to His Highness's words, it's really true! If the Yan army moves smoothly and advances the Qingzhou border from Dongguan County and other places to the south to the Huaishui line in one fell swoop, then their room for maneuver in Qingzhou will be greatly increased. There is the danger of the Yellow River in the north, the sea in the east, the mountains in the west, and the Huaishui in the south. In this way, it is almost the same as the land of Guanzhong, with these four stops, as long as they don't have problems themselves, no one can do anything about him! Tu Qi said suddenly.

"Yes! Therefore, Murong Ke is thoughtful and far-reaching! I didn't see the intention of this at first! With the current strength of the Yan Kingdom, it is obviously insufficient to occupy such a vast land. But if it is used to defend a Qingzhou, it is completely sufficient! Besides, the land of Qingzhou has the advantage of fishing and salt, which can make them recover their strength quickly! At that time, even if we want to win Qingzhou again, it will not be an easy thing! Li Xin nodded and sighed.

In this matter, he really admired Murong Ke, after all, he had prepared early. From this point of view, I am afraid that some important ministers and generals such as Murong Liang, King of Bohai, and Murong Ping, King of Shangyong, were sent to the south, and I am afraid it was not just for the war in the south.

What's more, I'm afraid it's better to go over there first to prepare for the relocation of the capital, so as to meet the follow-up team.

"Although Murong Ke's plan is powerful, it is a pity that he miscalculated the situation, so today, everything is not completely ready, so he has to start moving the capital." When Deng Qiang heard this, he couldn't help but sigh.

"He had long expected that we would have a war to destroy the country, of course, this matter is not a secret, we know it ourselves. However, he should have thought that this war might not break out until a few years later, and that the relocation of the capital was only his final preparation. What's especially critical is that this time he attacked Jiangzuo, in fact, he took a certain risk, knowing that we might also be invited by Huan Wen to send troops. It's just that he thought that we would only send some soldiers and horses to deal with Huan Wen, and he didn't expect that I would want to kill Yan in one fell swoop! Big, south! This one mistake alone made him have to come to this point now! Li Xin said slowly.

If this time, as in the past, he only dispatched some soldiers and horses in a certain place to obtain a small number of benefits, then with the strength of the Yan Kingdom, it was completely defensible.

And Murong Ke's most ideal design should be to find a way to negotiate peace with Huan Wen after taking the Huaishui line, so as to end the war in the south.

At the same time, with Murong Chui in the north, it should not be a problem to resist the small-scale attack of the Tang army. As long as the battle situation in the north is not completely eroded, then the entire overall situation is under control, and there is not much threat to Yan Guo.

It's a pity that Tang Jun's reaction exceeded everyone's expectations.

No one thought that after only about three years of repair, the Tang army would attack Yan on a large scale and destroy the Yan Kingdom in one fell swoop. After all, although the Yan State has been defeated repeatedly in recent years, it is still a big country because of its occupation of the Central Plains, and it still has a very strong strength.

"Murong Ke is now facing a dilemma, and he can't resist our attack. And in the south, if the peace talks with Huan Wen cannot be reached, he will fall into the point of being attacked by us and Jiang Zuo, in this case, the Yan Kingdom may not be able to avoid the fate of destroying the country in the end! Hong Yi thought for a moment and said.

"In this case, doesn't it depend on Huan Wen's thoughts? If he and Murong Kezhen reach peace talks, and finally the war in the south of the Yan Kingdom is over, then he will be able to deal with us with all his strength! Although we are not afraid, this is still very unfavorable for us to enter Qingzhou and completely wipe out the Yan Kingdom! When Tu Qi heard this, he couldn't help but be a little worried.

"Just reaching a peace doesn't have much impact on us. What I'm worried about now is that Huan Wen will stand with them and deal with us together! The matter of peace, starting from the overall situation of today, I think whether it is Huan Wen or Jiankang, they will agree. Even if they were killed and killed before, now many places in Donghai County have been robbed by Yan Guo! Li Xin pondered for a moment, and then said slowly.

"No, it won't! After all, we and Huan Wen are allies after all, and this time in the war, he asked us for help first, so we will send troops! If, in the end, he stood with the enemy and dealt with our ally together, wouldn't he be laughed at by the people of the world? Zhang Oyster frowned, as if he didn't believe it.

"Nothing is impossible, the reason why he will become our ally is because the interests are sufficient. If the interests of his alliance with Yan Guo exceed the interests of his alliance with us, then it is natural for him to betray us and switch to Yan Kingdom! Li Xin shook his head, not at all strange about this.

"If that's the case, then shouldn't we be prepared for it beforehand? Especially on General Zhao and Chen Kang's side, they are between the Yan army and the Jin army! Hearing this, Tu Qi hurriedly asked.

"Well, I'll write a handwritten letter later, and you send a powerful person to Zhao Ji and Chen Kang as soon as possible. In addition, the Shangluo guards were ordered to prepare and act immediately when necessary! After thinking about it for a while, Li Xin commanded.

"Yes, the minister will arrange this matter immediately!" Tu Qi hurriedly replied.

"Your Highness, now that the Yan Imperial Court has not moved its capital, we might as well take this opportunity to quickly go south, and block the way to the east before the enemy moves the capital to Guanggu!" Deng Qiang proposed at this time.

"It is inevitable to march into the army, but it is not easy to move south quickly. After all, we are still far from the land of Yecheng, and it is impossible to give up the county seat along the way. Otherwise, the battle line will be stretched too long, and it will be easy for the enemy to take advantage of it! Now Peng Lin is leading an army of 20,000 in the south, but there is no need to worry too much, they want to go south and no one can stop them, and if they want to retreat north, no one can beat them! As for our troops, if we slowly advance according to the previous plan, it will be a little inappropriate! Especially in order to move the capital, Murong Ke will definitely try his best to resist the situation of us going south! Li Xin agrees with this proposal, but how to act is a question that must be carefully considered.
