Yun Chang stood on top of the big boat and sailed along the canal all the way north into the ditch. After learning that these canals were all dug by Huaiguo, he was immediately shocked by this.

When he came to Huai'an, he saw that the prosperous city was even more suppressed, and Huai'an, as the largest city in the world, had more than 200,000 people living here.

This population is already half the population of some small princely states. Such a prosperous city shocked the prince of Yue.

Yun Chang came to be a proton and handed over the credentials and tribute, Wang Jin also gave a reply, recognizing Yue as a subject country, and severely reprimanded him for his alliance with Chu and demanded that Yue and Chu sever diplomatic relations.

The monarchs and ministers of the Yue State hurriedly agreed, and expelled the envoys sent by the Chu State from the Yue Kingdom, and at the same time accepted the supervision of the envoys sent by the Huai State.

After seeing that Yue Guo was so deferential, Wang Jin withdrew the army from the border, leaving only the soldiers who patrolled daily.

After the army withdrew, the mountains in the hearts of the people of Yue were also removed, and the Yue Hou breathed a sigh of relief.

After the surrender of the Yue State, the Huai State did not completely relax its vigilance, if it were not for the fact that the current environment of the Yue State was too bad and the road was difficult, the Huai State would not have left the Yue State at all.

However, after the submission of the Yue State, the Huai State began to send caravans to the Yue State for trade.

Huai's fine wine, food, refined salt, starch sugar, pottery, silk, lacquerware, grain, coarse salt, linen and other commodities are all hot goods, which are transported to Yue by caravans for sale, and then buy rhino horn, raccoon yarn, big wood, leather, preserved fruits, etc. and transport them back to Huai.

And under Wang Jin's instructions, the prices of the goods sold to Yue were not too expensive, but the purchased goods were given high prices.

Yue Guo was originally located in a remote, barbaric land, how could he not like these exquisite goods. In the past, Chu would also sell them these goods, but the price was not low, like now, the price is half lower than that of Chu.

It is human nature to like enjoyment, comfort, and food, and only a very small number of people can restrain their behavior, and the vast majority of the ministers and doctors in Yue are not this kind of people.

So in order to obtain money and enjoyment, these scholars and doctors began to let the people hunt rhinoceros and elephants, and instructed the people to go deep in the mountains to cut down giant trees.

For a time, the life of the people of Yue was even more difficult, and many people died in the mouths of wild beasts.

Although the people of Yue are not doing well, the tax revenue of Yue has increased a lot, and the whole country seems to be prosperous. The arrival of the Huai caravan brought a large amount of tax revenue to the Yue country, which also caused the Yue Hou to not notice that the people in the country were not doing well.

After a few years, news came from nowhere that the road to Vietnam was difficult to travel and that it was difficult for caravans to travel back and forth, resulting in high prices of goods, and even shortages of some items.

This point was felt more clearly by the ministers and doctors of the Yue Kingdom, so some scholars wrote to ask the Marquis of Yue to levy labor to repair the road. And also listed a lot of benefits of road construction.

It's just that after calculating, Yuehou found that the cost of building the road was very high, and then considering the question of the strength of Huaiguo, he hesitated, and finally refused.

However, although the proposal to repair the road was rejected, it also left a deep impression on the whole country.

Some of the doctors also felt that they should rest their roads so that they could sell more hides, raccoons, rhino horns, giant trees, etc., to make more money.

The huge profits made many of the ministers and doctors eager to move, so they began to repair roads in their fiefdoms. Huai Guo is happy to see this kind of behavior come to fruition. The caravan was instructed to tilt the nobles a little, and the other nobles, seeing the benefits, began to repair the roads in their territories.

The Huai caravan collected a lot of intelligence in the Yue country, and even the topographic map of the Yue country was drawn, and they have been preparing for the Huai country's invasion of Vietnam.

After several years, the topographical map of the territory of the Yue Kingdom was basically completed, and at the same time, the resentment of the people continued to accumulate because of the expropriation of rhino horns, animal skins, and giant trees by the scholars and doctors. It's just that until now, these problems are not serious, and at the same time, the road is not smooth, and Wang Jin has not

There are troops.

Moreover, at this time, it is morally untenable to send troops to attack Vietnam, after all, Yue is already a subject country of Huai. On the other hand, they are also worried that the State of Qi and Jin or the State of Chu will intervene.

Now these princes of the state and Zhou have deeply realized the danger of Huai, and dare not let Huai continue to annex and develop.

On the one hand, Wang Jin instructed the caravan to continue to develop in the Yue Kingdom, and on the other hand, he began to make trouble for the Jin, Qi, and Chu States to contain their energy.

After several years of development, the secret guard of the Huai State has developed an intelligence network in the Jin State. Since the death of Duke Wen of Jin, Duke Xiang of Jin reigned for a short time, and the six secretaries of Jin began to grow larger.

When the son of Jin Xianggong ascended the throne, he was even a young son, and state affairs could only be entrusted to Liuqing. Later, the Marquis of Jin gradually grew up, but the Liuqing was still in a high position, which led to the power and majesty of the Marquis of Jin being challenged.

There has never been peace between the monarch and the ministers, not to mention that there are also secret agents from the Huai State who have been fueling the trouble.

The Huaiguo caravan brought a large amount of wine, silk, and caramel for the Jin Marquis to enjoy, and at the same time secretly provoked the relationship between the Jin Marquis and Zhao Dun, the head of the Six Qings, which caused the relationship between Zhao Dun and the Jin Marquis to get worse and worse.

In particular, Zhao Dun participated in the alliance of the princes on behalf of the Marquis of Jin, exercised the rights of the Marquis of Jin, and sat on the position of overlord, which further encroached on the rights and prestige of the Marquis of Jin.

The contradiction between Zhao Dun and the Marquis of Jin has almost become public, as long as the person punished by Zhao Dun sends money to the Marquis of Jin, the Marquis of Jin will let him protect him. To do so is to humiliate Zhao Dun, Zhao Dun is the secretary of the Jin State, in charge of the court, and has great power. Will you have no temper and be humiliated?

The relationship between Zhao Dun and the Marquis of Jin made the politics of the Jin State chaotic, and he was powerless to target the Huai State for the time being. Without the pressure of the Jin State, only the Qi State was left alone, and the current strength of the Huai State could already start a war with them at the same time.

After expelling the envoy of Chu, Yue has broken off diplomatic relations with Chu, and Xiong Yun of Chu is now seriously ill, and it seems that his life is short, even if Huai Guo starts to cut down Yue, Chu State cannot contain Huai State.

It took Wang Jin ten years to finally cut off the foreign aid of Yue Guo one by one, and lured Yue Guo to take the initiative to build roads with money and goods.

However, before making a move, Huai Guo still needs to find a suitable excuse, after all, Yue Guo is now a subject country of Huai State. Soon Wang Jin thought of a way, he deliberately leaked the news of the attack on Yue to Yun Chang, the prince of Yue State, and Yun Chang escaped from Huai'an overnight after getting the news and returned to Yue to report the news.

So Huai Guo prepared to send troops to recruit Yue Guo on the grounds that Yue Guo was rude.
