Li Changjie naturally didn't know that Cai Dao wanted to use 35,000 soldiers to wrap up the entire Thang Long City.

Otherwise, Cai Dao would not have risked leaving that Western cavalry outside the city and not participating in the battle inside the city.

First of all, it is true that the city cannot fully exert the power of cavalry;

Second, it is necessary to prevent Li Qiande from abandoning the city and fleeing.

In the end, the number of cavalry was too small and too precious.

is the current 1,000 cavalry, or the Zhuang family, the Zhe family, the Yao family and the Liu family are put together.

Among them, it's not that the Zhe family can't get more cavalry, but if Zhe Kexing really has to give Zhe Keda too many personal soldiers, it will cause the suspicion of Zhao Xu and the princes of the imperial court.

Cai Dao has horses in his hands, but he has no plans to train cavalry on a large scale, after all, his future purpose is still to focus on the sea.

Therefore, the army led by Cai Dao this time is all newly recruited, and even being an army is a job, let alone cavalry. Moreover, the cavalry of a thousand men had to be concentrated so that they could play a greater role and not be dispersed.

The reason why Guo Zhongxiao did not oppose it was also due to these three considerations. After all, in this southern expedition, taking Thang Long City is actually just an addition, the key is to capture Li Qiande and the whole family, if Li Changjie can be punished, it will be better.

On the contrary, according to the people who claim hegemony in the land of Jiaozhi, there is a common characteristic, that is, the festival is not as important to the emperor of the Great Yue Kingdom as his own life.

Since bowing to the Song Dynasty, Li Qiande and Li Changjie have been paying attention to the domestic situation in the Great Song Dynasty all the time.

On the one hand, the monarch and the minister were still afraid that Shenzong or the emperor who succeeded to the throne wanted to take revenge on the Xining War.

On the other hand, they are still thieves, and they always hope that the Song Dynasty can be caught in the war between the Western Xia Kingdom and the Great Liao Kingdom, but in their lifetime, they will expand their territory and include the Guangnan West Road and even the entire Lingnan region into the territory of the Great Yue Kingdom.

However, during the nearly 20 years of peace, Li Qiande and Li Changjie were undiminishedly ambitious, but the elite soldiers who survived a hundred battles were gradually getting old, and the generals who could fight were also exhausted by the peacetime.

In the past two decades, not only the forbidden army of the Great Song Dynasty has slowly decayed, but also the soldiers in the Great Vietnam.

Nowadays, even the old enemy of the Great Viet Kingdom occupies the city and frequently shows favor to it, and if the soldiers do not experience war for a long time, the new soldiers will not be tempered by war.

……

After all, this is the capital of the Great Yue Kingdom, and Li Changjie's subordinates are indeed elite.

It took a very short time to find out the situation of the entire Thang Long City. However, it was limited to places that the Song army had not yet occupied.

In the direction of the east gate, due to Cai Dao's strict arrangement, Li Changjie's secret agents couldn't get close at all. And the north gate attacked by Guo Zhongxiao was also arranged by Di'an, and the temporary fortifications were no worse than those at the east gate.

However, because Guo Zhongxiao adopted a gradual approach, the dynamics of the Song army at the North Gate were easily grasped by Li Changjie. Moreover, Guo Zhongxiao also made a decision to die, putting those troops of the Great Yue Kingdom in front of his own position. This greatly slowed down the movement of the Song army.

On Cai Dao's side, although he did not clear all the forbidden troops of the Great Yue Kingdom stationed between the East Gate and the Imperial City, however, because these troops were warned by deserters one after another, although the main generals and deputy generals were no longer there, but there was the urging of the secret agents under the military resentment, and the middle-level officers in these barracks had to lead troops to try to stop Cai Dao's troops.

This kind of action of theirs was simply adding fuel, so Cai Dao easily broke these armies one by one, and did not delay the speed of the march at all.

Of course, not all the middle-level officers in the camp dare to make their own decisions, even those secret agents no matter how much they urge, they are indifferent.

Therefore, even if Li Changjie's spies found out the location of Cai Dao's troops at that time, by the time the news reached Li Changjie, Cai Dao had already advanced a long distance from the location just now.

After comprehensive intelligence, Li Changjie learned that it was very likely that the army of the Song Dynasty was attacking Thang Long City this time, but the number was too far behind that of twenty years ago. From the information he has obtained so far, he has deduced that the approximate number of the Song army is about 50,000.

However, through speculation about the number of the Song army, Li Changjie also basically figured out the intention of the Song army's commander to raid Shenglong City this time, that is, 'encircling three and one'.

Storming the east and north, leaving the west empty, and as for the south, it was a deadly trap at all, because since the Song army was able to quietly attack Thang Long City this time, then they must have gone all the way to the mouth of the Red River by sea. The only thing that Li Changjie couldn't understand was how the Song army could go straight to Thang Long City without alarming the Red River army of the Great Yue Kingdom.

If Li Changjie knew that the leading party he couldn't figure out was his nephew, I don't know if he would be angry to death.

After Li Zhongshun returned home, he once had the idea of reporting to his uncle. However, the thought only lingered in his mind for less than three seconds before he was thrown out. Let's not talk about whether his uncle will believe his words, Li Zhongshun will not forget that he himself is a general in the Red River Water Army! Song Jun sneaked in, and instead of being killed on the spot, he came back alive to report to him.

What's more, Li Changjie is not stupid, on the contrary, he is very smart, and he will naturally understand the strangeness. If the army of the Great Yue Kingdom wins, he will definitely not be able to escape death, but on the contrary, if that Dao Master really has to take Thang Long City, he will still have a glimmer of hope. Besides, Dao Ye also promised to let go of the family he had thought of.

How to choose is not difficult for Li Zhongshun.

Li Changjie's home is in Nancheng, which has always been a settlement for nobles and wealthy merchants because of its proximity to the Red River crossing. Therefore, along the way, he took his family, his family, and the guards who fled with him, but he did not encounter the army. Even if a soldier on night patrol discovered their group, with Li Changjie's identity, these people did not dare to stop him.

Along the way, Li Changjie also took the family members of the guards with him, and went straight to Li's house all the way.

Speaking of Li Changjie, after analysis, he suggested to Li Qiande: "Your Majesty, it has been clearly investigated that there are two enemy forces attacking Thang Long City. The old slave decided to lead his army to deal with the enemy army in the direction of the north gate first. The old slave believed that with General Ruan Chong guarding the imperial city for His Majesty, it would definitely be foolproof. The old slave will definitely completely destroy these two enemy forces before noon. ”
