Elder Cai Dao was able to break through the palace of the Great Yue Kingdom with Thunder Law, which was something that no one had thought of before, and it was daylight and there was no rain in Thang Long City.

The thunder broke through the city during the day and on a sunny day, which greatly boosted the morale of the Song army. Moreover, Daochang Cai has also made a promise before. In addition to the Imperial Palace, the Song army will plunder the city of Thang Long for three days.

Of course, the three days of plunder that Cai Dao spoke of were different from what those nomads did when they entered the Central Plains.

After Cai Dao prepared to take Thang Long City, he first used the surrendered troops in the city to drive the people of the city out of the city, and then sent soldiers to various houses to loot money and treasures.

As for the Vietnamese troops who surrendered to themselves, some of them guarded the people of Thang Long City outside, and some of them distributed the food in the city to these people, which was considered to stabilize them temporarily.

After that, after the money was transported by sea to the people recruited from the coastal areas of Lingnan, all the valuable things in Thang Long City were emptied. Taking advantage of this opportunity, Cai Dao also wanted to lead his army to attack several cities around Thang Long City.

As for the people who were driven out of the city, it was also necessary to distinguish that those who could speak Chinese could continue to live here, but those who could not speak Chinese would be doomed in the future, and the women would be transported to Luoyang Mansion and given to the men who expanded the city there, while the men would be transported to the city where Zong Ze was located.

The original Cangzhou was changed to the current Tianjin Prefecture.

This is a newly built coastal city in the Great Song Dynasty, and the location of the new city naturally cannot be Tianjin in the later generations. Because, it is still the land of the Great Liao Kingdom.

Xincheng was located on the border of Song and Liao, and now it has become a gathering place for Song and Liao trade.

In order to prevent the Great Liao State from interfering in this matter, the Song State sent envoys to the Liao State at this time, explaining the reasons and uses for the Great Song State to build a city here, and also specifically explained that even if the city built a city wall, it would not be higher than the height of an ordinary willow tree, and if the Liao State was still not at ease, it could send envoys to the city to supervise.

For this reason, Cai Dao also specially invited Zhao Xu to allow the Cai family in Xianyou County to sell the shipping ships he built to the merchants of the Great Liao Kingdom, so that these giant merchants of the Liao Kingdom could say good things for them in front of Yelu Hongji.

You must know that the giant merchants of the Great Liao Kingdom have long coveted the shipping ships manufactured by the Cai family, but Song Shenzong did not allow this matter, and the Empress Dowager Gao Taotao, Wen Yanbo, Lu Gongzhu and Lu Dafang did not accept this stubble at all. Therefore, the two sides have been deadlocked here.

It took so much explanation and effort to dispel Yeluhongji's suspicions.

The reason why Cai Dao was able to successfully persuade Zhao Xu to sell advanced sea ships at the beginning was also because the Great Song Kingdom had always monopolized this technology, and the maritime trade was very profitable.

Instead of letting the Liao people develop their own shipbuilding technology, it is better to sell the relatively backward ships they built to the merchants of the Liao State, so as to save them from developing better ships.

On the other hand, the northeast of the Liao State is indeed rich in timber suitable for building ships, and if the business of selling ships is opened, the Great Song Kingdom will be able to buy more timber from the Great Liao State. On the contrary, it can reduce the damage to the natural environment in the Great Song Dynasty.

It was the large-scale destruction of the environment in the northwest region in the Ming and Qing dynasties that made some of the originally wooded lands in the Hetao eventually become deserts, such as the Yulin Forest in later generations. As you can tell from its name alone, Yulin was originally a densely wooded place.

In short, there is a big surprise waiting for these young people of the Great Yue Kingdom in Tianjin City.

However, before that, Cai Dao must use his team of less than 20,000 people to completely break the Dayue army besieging Beicheng.

If it were a change of peacetime, Li Changjie would definitely not go to Beicheng, because it was very likely that the army would fall into the encirclement of the enemy. However, Li Gande is now walking through the south gate, how can Li Changjie not be in a hurry?

Helpless, Li Changjie could only personally lead the army to march directly to the north, even if the Song army really dared to block his way on the other way. Li Changjie was not ready to fight hard with the other party, he was ready to use the method of gecko tail breaking, and use a part of his troops to contain the Song army from the front, while he himself led the rest of the troops to slide away from the flank.

Because, even at this moment, Li Changjie always firmly believed in his own judgment, the Song army's sneak attack on Dayue Kingdom this time must have brought less than 50,000 troops, and it is very likely that less than 40,000 people actually entered Thang Long City.

After a fierce battle between the two Song armies for most of the day, even if the forbidden army in Thang Long City was exchanged for ten, it could greatly reduce the Song army's troops.

Half of the points, plus those soldiers stationed at the east gate, then, it is very likely that the enemy in front of him is less than fifteen thousand.

It's a pity that Li Changjie only guessed half right.

Cai Dao's real loss of the Song army along the way was the small group of 3,000 people of Zhe Kerou, and the 50,000 troops under Li Changjie were the strongest among the Song army's troops today.

Sure enough, Cai Dao was waiting in front of the north gate of the palace, but this time, he did not order his men to continue the fortifications.

This is because Cai Dao knows very well in his heart that there is only one choice for the opponent at this moment - to rush through the blockade.

Li Changjie led his troops this time, not to fight with him, but to sacrifice a small force to hold his troops, while Li Changjie himself broke through from the flank, he just wanted to join Li Qiande in Nancheng.

It may seem incredible that a team of 50,000 people can break through a team of less than 20,000 people, but in fact this is the reality.

If Li Qiande had been confused in his heart in a hurry, it was very likely that he would have listened to the encouragement of his subordinates and crossed the Red River by boat.

It seems to be very safe, because once the Red River is crossed, you can go to the south, south, and northwest in the north of the Great Viet Kingdom.

What's more, there are now 100,000 troops stationed on the Song-Vietnam border. As long as he recruits back 80,000 people, or even 50,000 people, Li Changjie will be enough to recover the now half-lost Thang Long City.

Since Lu Huiqing took office as the prefect of Guizhou and the transfer envoy of Guangnan West Road, the situation on the Song-Vietnam border has once again become unprecedentedly tense.

However, Lu Huiqing was not one of those fools in the Xining period, he first used a large army to steadily defend the important passes on the border.

100,000 mountains, once those important checkpoints are guarded, the army of the Great Yue Kingdom will want to invade the Great Song Kingdom smoothly as it did in the Xining period, and it will be better than climbing to the south of the sky. Moreover, Lu Huiqing's methods are not only like this, he also used a lot of money to recruit a lot of barbarian warriors in the mountains, and the head of a Vietnamese army is consistent money, but the people don't want it.

In a short period of time, the border army of the Yue Kingdom lost many soldiers.

In order to prevent the Song army from sending troops to retaliate again, and also to curb the endless sneak attacks of those barbarians, Li Qiande sent an additional 50,000 troops to reinforce the border army. This directly led to the fact that the military strength in Thang Long City became a little empty compared to before.

But the premise is that Li Qiande can really cross the Red River by boat.

Therefore, break through as soon as possible and join Li Qiande as soon as possible, Li Changjie can only do this.

However, although Li Changjie's idea was good, once it was put into practice, it was completely disintegrated by Cai Dao.

Since learning that the palace was breached by the Song army, Li Changjie also knew that the morale of the Vietnamese army under his command was low, so he specially sent his righteous son Li Sijie to lead 20,000 people as the vanguard to block Cai Dao's interception team in the front.

Li Changjie himself led 20,000 men, and when Li Sijie blocked the enemy in front of him, he immediately led his team to slide through the defense line arranged by the Song army from the southwest side.

Of course, Cai Dao's troops on the front cannot have 20,000 people, and even if Li Changjie repeatedly increases the opponent's strength, he also knows that the frontal deployment is at most 10,000. But Li Changjie still sent 20,000 people to resist Cai Dao's attack, which shows that he attaches great importance to and fears the commander of the Song army on the East Road.

However, when Li Sijie really confronted Cai Dao, he saw a young Taoist priest in a Taoist robe appear in front of the battle.
