The kings of Chu and Wei, who were far away in the capital, received a letter from Zhao Yao at the same time. In the letter, Zhao Yao told them that King Han wanted to cooperate with him in business and would send someone to the Swamp Mansion. He specially sent someone to investigate King Han, and the result of the investigation was that King Han had been doing business in Youzhou and had business dealings with the Western Regions. In addition to doing business, Han Wang did not do anything else in private. At the end of the letter, he repeatedly stressed that he felt that King Han was not as "clean" as in the investigation, and told the King of Chu and King Wei to be careful and wary of King Han.

Yang Ling saw that after reading the letter, Yang Ling's face was a little unpleasant, and he hurriedly asked with concern, "Your Highness, what did His Royal Highness the King of Han write in the letter?"

King Chu handed the letter in his hand to Yang Ling, "Sir, please take a look."

Yang Ling took the letter and looked down seriously. After reading it, his face became a little solemn.

The King of Chu asked, "Sir, what do you think?"

Yang Ling returned the letter in his hand to the King of Chu and said in a deep voice, "I have the same thoughts as His Royal Highness the King of Han, and the King of Han will definitely not be as clean and simple as the investigation."

King Chu's impression of King Han is the same as Zhao Yao's. In my impression, King Han and King Chen have been playing with King Zheng, looking like a hanger and a gentleman. When they were children, they often joked and bullied the tenth brother. Anyway, nothing good to impress.

After that, King Han went to Youzhou as an adult, and he didn't come back all these years, King Chu didn't pay attention to him, but he didn't expect King Han to be a hidden person.

"Your Highness, I didn't expect King Han to be an unfathomable person." Yang Ling frowned and said with a calm face, "We miscalculated and actually thought that King Han was an opponent to be feared."

"It was the king's negligence." The king of Chu thought that King Han, King Zheng, and King Chen were all the way, so there was no need to worry.

"Your Highness, now it seems that in addition to King Wei, King Han is also a fierce opponent." After Yang Ling read the letter, a cold sweat broke out on his back, "Fortunately, His Royal Highness the King of Han found out that King Han is not simple, otherwise we will definitely be ...... by King Han in the future" In the future, when the King of Chu and the King of Wei are fighting to the death, it is not impossible for the King of Han to take advantage of the situation and annihilate the King of Chu and the King of Wei in one fell swoop. When the time comes, it is really a wedding dress for King Han.

The King of Chu bowed slightly: "This time it's thanks to the tenth brother." Otherwise, they don't know when they will find out the true face of King Han.

"Your Highness, you have to send someone to investigate King Han in depth immediately." Yang Ling said with a grim expression, "We must find out what King Han has done sneakily over the years, otherwise it will be too bad for us." Now they are in the light, and the king of Han is in the dark. If you don't find out, I don't know when you will be injured by King Han's cold arrow.

King Chu nodded his head and immediately took out a map from the bookcase. This map is a map of the territory of the Great Zhou Dynasty that was redrawn by the first emperor when he first ascended the throne. The King of Chu stared at Youzhou on the map.

Yang Ling saw the Xiongnu grassland above Youzhou, and an idea flashed through his mind.

"Your Highness, will King Han secretly collude with the Xiongnu?"

King Chu's eyes suddenly became fierce, and his tone became cold: "If he dares to collude with the Xiongnu, I will never spare him."

"It's only been a long time since the Yuan family's affairs have passed, and I don't think King Han will blatantly collude with the Xiongnu." Yang Ling thought of one more thing, "Youzhou is an important place in the north after all, and the emperor will not prevent King Han from colluding with the Xiongnu if he asks King Han to go to Youzhou. Besides, the Zhenbei camp is the emperor's direct military camp, and it will inevitably monitor King Han's every move."

"What Mr. said is reasonable, it is impossible for King Han to collude with the Xiongnu under the nose of his father." The King of Chu lowered his head and scanned the map with a sharp gaze. Soon, his eyes stayed on the Western Regions.

Yang Ling also thought of the Western Regions. He smiled and said, "It seems that Your Highness thinks the same as me." He pointed to the Western Regions on the map and said, "His Royal Highness the King of Han said that the King of Han has been doing business with the countries of the Western Regions for all these years, so it is very likely that the King of Han has ulterior transactions with the countries of the Western Regions." The four words "unspeakable", Yang Ling bit very hard.

He added, "Your Highness, you can send people to investigate the countries of the Western Regions, I think there will be unexpected results."

"That's what I mean."

Many years ago, many countries in the Western Regions were friendly with the Great Zhou, and sincerely begged the Great Zhou to send people to their countries to teach Confucianism. The emperor ordered to send people to the Western Regions

Confucianism is taught and propagated in various countries. The candidates to be sent were selected by Taixue, that is to say, they were finalized by Li Fuju.

Over the years, Confucianism has blossomed brilliantly in the countries of the Western Regions, making many people in the Western Regions fall in love with Confucianism. In recent years, the countries of the Western Regions have sent many young talents to study in Taixue in Dazhou.

Not only that, but many of the people who were sent to give lectures in the Western Regions at the beginning also served in the Western Regions. They are very popular and respected in the countries of the Western Regions. Although they are not particularly important positions, they can more or less gather a lot of information in the Western Regions.

Some of the people sent to give lectures in various countries in the Western Regions were talents carefully cultivated by the Li family. They went to the countries of the Western Regions, and in addition to lecturing, they also had other tasks.

In a sense, these people sent to give lectures in the Western Regions were the eyes of the King of Chu in the Western Regions.

"The Southern Wei people are also doing business in the Western Regions, and there are still many Southern Wei people who fled to the Western Regions, they should soon be able to find out what King Han has done in the Western Regions all these years."

King Chu said, "He won't tell me."

"That's right."

The king of Chu said coldly, "This king is not uncommon, he told me."

When it came to the people of the Southern Wei Dynasty, Yang Ling suddenly thought of something, and his face instantly became horrified.

"Your Highness, the ability of the Southern Wei people is not small, King Han can make transactions with the people of the Western Regions under the noses of the Southern Wei people, and he will not be discovered, you say that King Han is ......" Thinking of this, Yang Ling's heart felt cold.

Yang Ling's words made King Chu's brows furrow even deeper.

"If that's the case, then King Han's strength is even higher than that of the Southern Wei people." Yang Ling's face became more and more solemn, "Your Highness, King Han's strength is even more terrifying than we imagined."

"Sir, don't scare yourself yet." The King of Chu comforted Yang Ling and said, "What the King of Han did in the Western Regions may not be able to hide from the Southern Wei people."

"Your Highness, what do you mean?"

The king of Chu said unhurriedly, "Let's investigate first."

Yang Ling understood what King Chu meant, nodded in agreement, "Yes, investigate first."

"What I'm most worried about right now is the tenth brother." Compared with himself, King Chu was more worried about Zhao Yao, "King Han suddenly asked his tenth brother to cooperate in business, is it really a simple business, or is there another purpose?"

"Your Highness, are you worried that King Han will be unfavorable to His Royal Highness King Han?"

"I'm worried that the tenth brother is not the opponent of King Han." King Chu said worriedly, "I'm also worried that King Han wants to take all the business of the tenth brother for himself, and King Han will use the trade conference to contact countries such as Annam and Johor."

"Your Highness, His Royal Highness the King of Han can find out that King Han is not simple, he should be wary of King Han, and he will never let King Han rob his business, as for King Han wants to contact countries such as Annam and Johor, I am afraid it will not be so easy." Yang Ling comforted King Chu and said, "There are our people in countries such as Annan and Johor, as well as the people of the Acting King and King Jing, what the King of Han wants to do in these foreign countries, but he can't hide it from us and the Acting King and their people."

"I hope I've thought too much."

"Your Highness, you have forgotten that our people have arrived in the Swamp Mansion, if King Han will really be unfavorable to His Royal Highness the King of Han, you can let our people protect His Royal Highness the King of Han." Yang Ling thought to himself, if nothing else, just say that His Royal Highness the King of Han can find that King Han is not simple, and you can see that His Royal Highness the King of Han is not simple. If King Han really wants to be unfavorable to His Royal Highness King Han, I'm afraid it won't be so easy.

He hoped that King Han would be unfavorable to His Royal Highness King Han, so that he could see how His Royal Highness King Han dealt with King Han, and he would also know His Royal Highness's scheming and methods at that time.

"Your Highness, I heard that the acting king and they are all sending people around looking for relics, pagodas, Buddhist beads, Buddhist scriptures and other things, don't you really plan to offer other things on the death anniversary of the Empress Dowager?" Yang Ling thought of Zhao Yao, who was far away in Lingnan, "Has His Royal Highness the King of Han said that he would offer something on the death anniversary of the Empress Dowager?"

King Chu shook his head slightly, "I didn't tell the tenth brother about this."

"You didn't tell, will King Wei tell His Royal Highness the King of Han?"

"I don't know. If the tenth brother really wants to offer something else, he should write to me." King Chu thought that Zhao Yao was busy with his trade conference now, and chuckled and said, "Tenth brother probably not

Thinking about it, he must be busy receiving foreign guests on his way to a trade conference."

"I don't know what the trade conference held by His Royal Highness King Han will be like." In this regard, Yang Ling was very curious, if it wasn't for the swamp mansion being too far away, he would definitely go and see it.

"It's going to be very lively, but unfortunately I can't see it myself." Regarding Zhao Yao's holding of the trade conference, the king of Chu was heartbroken, and he had been writing to ask Zhao Yao how he was preparing. Not only that, but he also helped Zhao Yao with advice. In order for Zhao Yao to hold a good trade conference, he rummaged through books. He was also worried that the royal families and merchants of Annam and Johor would underestimate Zhao Yao, His Royal Highness the King of Han, and not go to the trade conference, so he specially wrote a letter to them to let them know that the King of Chu attached great importance to the younger brother of the King of Han. They don't look at the face of the King of Han, but also look at the face of the monk of the King of Chu, and go to the trade conference held by the King of Han.

People from Annam and Siam and other countries were still very face-saving to the King of Chu, and they wrote back to the King of Chu one after another, saying that they were very willing to participate in the trade conference held by His Royal Highness the King of Han, and they also wanted to do business with His Royal Highness the King of Han.

"If it weren't for Your Highness, you secretly helped His Royal Highness the King of Han, I'm afraid that Annan and other countries would not pay attention to the trade conference held by His Royal Highness the King of Han." The King of Chu really worries about His Royal Highness the King of Han in everything, and secretly helps His Royal Highness the King of Han solve all the problems.

Yang Ling was wrong. The king of Chu was very favored and reused by the emperor, and Zhao Yao, His Royal Highness the King of Han, was indeed not favored on the surface, but the royal families of countries such as Annam and Siam would not not come to the trade conference because of this. They won't get along with money, and they won't let go of money without making money.

The things that Zhao Yao made were not available in their country. The most important thing is that the conditions offered by His Royal Highness King Han are very generous. Before His Royal Highness the King of Han came to Lingnan, they secretly did business with Lingnan officials, and at that time, Lingnan officials raised taxes layer by layer, and they also made a lot of money. Now, His Royal Highness the King of Han has waived more than half of the customs duties, and they will earn several times more money than in previous years. Unless their brains are broken, they despise His Royal Highness the King of Han and do not come to the trade conference.

Moreover, His Royal Highness the King of Han, who can make glass, all kinds of precious spices, all kinds of new tea, and farm tools, is by no means a fool, let them look down on and bully.

To tell the truth, it is more important to have a good relationship with His Royal Highness the King of Han than to have a good relationship with the King of Chu or His Royal Highness the Acting King. Because the benefits brought to them by the King of Chu and the Acting King are not as much as those brought by His Royal Highness the King of Han.

I heard that His Royal Highness the King of Han recently made something to prevent smallpox, and even if it was for this, they were going to come to the trade conference.

Smallpox is not only present in Dazhou, but also in other countries, and the extent of smallpox in countries such as Annam is more severe than that of Dazhou. Also, their doctor was helpless against smallpox. When smallpox occurred, they buried the people who had smallpox, and they set fire to the villages that were infected with smallpox.

Over the years, there have been many royalty members from countries such as Siam and Johor who died of smallpox. The emperor of their country also died of smallpox. If there really was a way to prevent smallpox, they would do whatever it took to get it.

Yang Ling looked down on Zhao Yao, and also looked down on the royal families of Annan and other countries.
