Yu'er was once the border between Wu and Yue, and now it has been completely occupied by the Song army.

Just yesterday, the Xuanniao Army of the Song Army directly defeated more than 6,000 people from the vanguard of the Vietnamese army and took down the north gate of this Yue Di. When Le Yi arrived here, he sent a division of the Song army, plus 3,000 Wu troops to guard this place, and after ensuring the rear road of the Song army, he led the army straight to Huiji.

Huiji is the real core of Yuedi. As a scholar from the Central Plains, Le Yi only knew that the Yue Kingdom was broken by the Wu State in the past years, and the Yue King Goujian relied on the fiefdom of more than 100 miles to finally revive the Yue Kingdom, and then successfully destroyed Wu for revenge.

However, after the local Wu people told him the true details of Yuedi, he couldn't help but be a little surprised. The size of the Yue Di is naturally far more than the core land of more than 100 miles of Huiji, the territory of the Yue Di is extensive, and its size is by no means under the Wu Land.

However, in addition to the surrounding area of Huiji, Yuedi is a fertile plain and suitable for farming, and most of the other places are mountainous. And those Yue people in the mountains, even the Yue Kingdom in the past, can only be fettered with generous gifts, and do not really rule them.

For the people of the mountains and wilderness in the mountains of Yuedi, that is, Shanyue, Le Yi is very interested. According to what the Wu people said, these people of Shanyue should not belong to the Dongyi clan, nor to the Nanban that everyone generally agrees on, but some new tribes.

In the world at this time, the vision of the Chinese countries is actually not narrow at all. In today's countries, all the large countries in the middle of the country will expand to the "foreign lands" around China. For example, the Qin State attacked Xirong to the west and destroyed Bashu to the south; Zhao attacked Beidi to the north; After the new monarch ascended the throne, the Yan State is said to have also launched a war against Donghu in its northeast.

In the Song Kingdom, because of Dai Yan, a traverser, as the monarch, all the subjects of the Song State were familiar with geography and had a strong interest in the surrounding areas. This is not only because geography is a compulsory item in the Song Imperial Examination, but also because all those who can draw accurate maps of places that the Song Kingdom does not know are highly rewarded.

As the chief of staff of the Song Army, Le Yi is not interested in these rewards. Rather, as a geography enthusiast, he has a strong interest in the development of geography.

The geography of the Song Kingdom itself had the advanced theories provided by Dai Yan, and after Zou Yan, a famous scholar under Jixia, also came to the Song Kingdom, there were people who were really interested in geography. Although Dai Yan had sponsored the disciples of the Agricultural and Mo families to travel around when he was only a feudal monarch before, his purpose was only to find precious resources, not to promote the development of a discipline.

The philosophy of the Onmyoism, which is rooted in astronomy and geography, is the school that is most interested in geography. In the Song Kingdom, the Yin-Yang School was not only directly funded by Dai Yan, but also cooperated extensively with the military, the nobles of the East China Sea, and the captains of ships who were on the sea. They measure the world with their own footsteps, explore unknown areas, and clearly draw unknown places on a new map.

As a military boss, Le Yi is also interested in the development of geography. Today's Song State is so powerful, there may be more and more foreign wars in the future, if you don't know the situation of the world, how can you make immortal contributions in this magnificent change?

The combined forces of Song and Wu, in just a few days, arrived at Yuedi Huiji from Yu'er in the north of Yuedi. At this time, the nobles of the East China Sea from the sea route had already taken the lead and attacked Yue Di from the sea route.

The attack from the sea made the Yue people unbearable. Faced with this scene, Wang Chao, the leader of the Yue people, could only disperse some troops and patrol around along the coastline. When the Song-Wu coalition army came to the vicinity of Huiji, the army in his hands that originally exceeded 60,000 was only more than 40,000 at this time.

The defeat of the Vietnamese army's advance made him know the strength of the Song army, so as soon as Fang saw the main force of the coalition army, he immediately led the army back to Huiji City and closed the city gate.

At the same time, he began to send envoys to the Song army camp to tell Le Yi that he knew that the Yue people were not the opponents of the Song State, and the Yue people were willing to surrender; As long as the Song State is willing to recognize the autonomy of the Yue Di, he will immediately offer a surrender to the Song State!

According to Wang Chao's understanding, the countries of the Central Plains have always attached great importance to their reputations. In the Spring and Autumn Period, any big country liked the grand occasion when the four countries invited to surrender and the countries came to the court. Even the State of Chu, after the destruction of the Yue State, gave the Yue people the right of autonomy?

However, as soon as Fang sent such a suggestion to the Song army camp, before Le Yi could speak, he was immediately opposed by a large group of people. None of the nobles of the East China Sea and the heroes of the Wu people who took refuge in the Song State were willing to accept the surrender of the Yue people!

The obvious reason given by these people is nothing more than that the Yue people are barbarians, and they have always been afraid of power and not virtuous. It is only when the knife is actually on their necks that they sense the danger and begin to relent. And once the strength of the host country is slightly weaker, the Yue people will turn against their master! Isn't the state of Wu, which was destroyed by Gou Jian, the best example?

For these reasons, Le Yi naturally scoffed. The backlash of the Yue people, in the final analysis, is just something that a ruler like him should consider, when did the nobles of the East China Sea and the Wu people be so kind and willing to consider the country?

In the final analysis, these people still have a fancy to the rich territory of Yuedi. Today's Song State, whether it is the common people under it, or the nobles of the East China Sea, or the Wu people who are just willing to accept the rule of the Song State, are deeply influenced by the Yang Zhu School, and the consideration of problems is based on actual interests, and there has never been the practice of the Central Plains countries that can even give up part of their interests for the sake of dignity and fame!

For such a change, Le Yi doesn't know whether it's good or bad. From a national point of view, he naturally hoped that the entire country of the Song Kingdom would become rational and consider problems in terms of interests. However, at the private level, it is estimated that no one will have a good impression of a mercenary person, and everyone still wants to have more human touch.

As a general who is familiar with people's hearts, Le Yi is naturally humane. Since at the moment, the nobles of the East China Sea and the Wu people are opposed to negotiating peace with the Yue people, then he will not disobey everyone's opinions, not to mention that he also thinks that the Yue Land will be solved at one time, and it will be easier for the Song State to gain a firm foothold here!

The Yue envoy returned to Huiji City with a depressed mood. When Wang Chao learned that the generals of the Song army had rejected the Yue people's request to surrender, he did not panic, but directly began to gather all the Yue commanders, and said to them: "We have grown up in this land since childhood, and now the Song State has come from the north, intending to drive out my people and occupy my territory. I didn't want to hurt the lives of our people and negotiate peace with the Song Kingdom, but the Song Kingdom disregarded our wishes and was determined to force us to death! For today's plan, we can only lead our people out of a way of life by fighting to the death with the Song people! ”

Wang Chao's words were impassioned, but it also made many Yue people begin to have confidence. At this time, they will not think about it, before Wang Chao took the initiative to ally with the Chu State, took the initiative to provoke the Song State, and declared war on the Song State.

Although Huiji City is the only big city in Yuedi, with the rude city-building technology of the Yue people, this city can never be compared with the cities of the Central Plains. For this point, whether it is Wang Chao or the Yue people, they all know this. They didn't have the luxury of expecting that the low walls of Huiji City would be able to withstand the attack of the Song army that broke through Wucheng!

Therefore, the only way to do it is to directly start a war with the Song army outside Huiji City!

After the specific battle plan was laid out and most of the Yue commanders retreated, Wang Chao specially left a few cronies and said to them: "Now that the Song State is attacking strongly, even if we try our best to resist it, we will never be able to resist it." For the sake of today's plan, we can only take advantage of the defeat of our army to retreat from Huiji to the mountains, so as to leave a way for us to survive. As long as we subdue the surrounding Shanyue tribes, once there is a change in the land, we can return to our homeland again. ”

When a close confidant heard this, he immediately asked with a sad mood: "Lord, is it true that the Song army is so powerful that we don't have the slightest strength to resist?" ”

Wang Lan sighed and said: "In the past, when we were strong, we were invincible in Yuedi, but as soon as Chu General Zhao slipped here, what happened to us, don't you know?" This time, the general who led the Song-Wu coalition army to come, I have already found out, his name is Le Yi, he has already defeated Zhaohua in Yunyang, and let the Chu army abandon Yunyang and retreat to Jinling. Do you think we can still compete with it now? ”

When everyone heard this, they all fell silent.

"We can't defeat the Song army, but these leaders are definitely unwilling to withdraw from Yuedi. Since they are willing to die, then I will fulfill them. The biggest reason why my Yue country was destroyed and the Yue people fell to this point is that my Yue country is not like the Central Plains countries, the etiquette system is not strict, and even the king has no authority. As long as these leaders die in the war, or their power is greatly weakened, then with the power in my hands, I will be able to unite the Yue people, and at that time, I will be the authority of the Yue Land, the real king of Yue! Wang Chao then added, I don't know if these words are meant to be heard by his cronies, to encourage them, or to find an excuse for his cowardice.

On the same day, the Vietnamese army sent a war letter to the Song army, agreeing that the two sides would fight a decisive battle in three days. Le Yi didn't think about it, and directly agreed in one go.

At the appointed time of engagement, the Song-Wu coalition army and the Vietnamese army appeared on the battlefield at the same time, and Le Yi only took a brief look at the appearance of the soldiers on both sides, and he had extremely confidence in this battle.

The Song-Wu coalition army, everyone had iron weapons in their hands, and the worst ones were also wearing whale skin armor made in batches by the Taoqiu factory. On the other side, although the Vietnamese army seemed to be relatively numerous, only nearly half of the soldiers had metal weapons in their hands, and the rest could only carry stones and wooden sticks. As for the armor rate on their bodies, it is even lower, tens of thousands of troops, and the people who can possess leather armor are only a few thousand.

Such a huge disparity in force is not only caused by the special situation of the Song State and the Yue Kingdom (the Song State continues to develop, and the Yue State has perished), but also due to the huge development imbalance between the two sides!

For such an "unequal" war, Le Yi did not despise it at all, and as soon as he made a move, he went all out, and directly let the Song army take the lead in attacking.

The Yue people on the opposite side, in the face of the attack of the Song army, did not retreat, and under the leadership of the leader of the Yue people, Wang Chao, they rushed straight towards the Song army. Under the leadership of Wang Chao's pioneers, the leaders of Yuedi did not doubt him, and they were all brave and heroic, and personally launched a decisive charge against the Song army.

What the Vietnamese army did not notice was that not long after the battle between the two sides began, Wang Chao was "wounded" by the Song army, and then quickly retreated to the end of the army. And Wang Chao's real cronies also began to shrink their forces continuously, shrinking all their main forces back.

This engagement, which did not surprise him at all, ended in the complete defeat of the Vietnamese army. Subsequently, he immediately led the main force of the Vietnamese army, mainly his own cronies, and fled from the battlefield to the surrounding mountains.

The Song-Wu coalition army defeated the Yue army, but did not get the news of the enemy leader Wang Chao, which made Le Yi a little surprised. But then he didn't care, and after he ordered the army to clean up the battlefield, he began to send the army into Huiji City.

Entering Huiji City not only means that most of the land of Wuyue belongs to the Song State, but also represents the influence of the Song State at this time, which has reached the southernmost southeast direction known to the Central Plains countries at this time.
