"Kunmi? Kunmi?" After the postmaster said this, he noticed that the expression of the young man in front of him was not right, so he called him twice in a hurry.

Lu Xuan came back to his senses, and forced his expression back to normal. He smiled and said, "Thank you for letting me know, Yicheng."

The postmaster looked at Lu Xuan with some concern, and when he saw that he seemed fine, he nodded and left.

After he left, Lu Xuan sat there for a long time without moving, his expression looking a little dazed.

During these few months, he had used his utmost efforts to settle down Xiao Wusun. Although the city was not well built, his subjects had settled down.

Then he led his men to attack Dayuan.

Of course, it was not entirely Xiao Wusun who sent troops, but they joined forces with the Han Dynasty. After all, they were fighting for the Tianma for Liu Che's face, and Xiao Wusun played a helping role in this matter.

However, the general sent by Liu Che was really incompetent. It was said that he was a man who had defeated the Huns before, and his name was Zhao Po Nu.

Originally, Lu Xuan had prepared to assist and gain some benefits at the same time, but he never expected that Zhao Po Nu would lead an army of 100,000 to be defeated by the Kingdom of Dayuan and flee in panic.

Lu Xuan had no choice but to switch from support to main attack, and then directly broke into the capital of Dayuan, captured their king, and snatched the Ferghana horse.

Lu Xuan left many Ferghana horses for the Wusun people, selected a few good ones, and escorted the King of Dayuan to Chang'an.

Among these horses, there were several foals that he left for Liu Tan. Although those foals were small, in his opinion, they were actually better than the ones he chose for Liu Che. One of the little white horses was particularly good and had a good appearance. Its pair of black eyes were very gentle, and it was a good match for Liu Tan.

Lu Xuan originally wanted to send the horse to Liu Tan in advance, but unexpectedly, when he arrived, the person he was looking for was no longer there.

Even after Liu Tan became a vassal, he had almost no chance to meet Liu Tan.

Even as a vassal state, Lu Xuan had to be aware that he couldn't just wander around. Liu Tan's fiefdom... he probably couldn't go there.

For a moment, even though Lu Xuan never gave up, he couldn't help but feel discouraged.

In fact, compared to all these, what made Lu Xuan most sad was probably that Liu Tan never thought of telling him from beginning to end.

He had settled people in the temporary city where he had taken Liu Tan before. If Liu Tan sent him a letter, he would definitely receive it. However, he did not receive any information about Liu Tan from beginning to end.

For a moment, he suddenly remembered a word he had learned before: fate.

No, the relationship between him and Liu Tan was all forced by him.

Even Lu Xuan felt a little tired. He had been chasing that figure, but it seemed that no matter how hard he tried, he could not catch up.

Lu Xuan looked out the window. Chang'an was so prosperous, why did he want to become a vassal? Did he not want to see him anymore?

Just when Lu Xuan was feeling sentimental, Aga Mu walked in happily and said, "Kunmi, the little prince is now the King of the North."

Lu Xuan looked at Agamu expressionlessly and began to wonder if this was the emotion a friend should have. Unfortunately... he could never put himself in the position of a true friend. The so-called friends were just excuses he used to cover up his true purpose.

Ajiamu looked up and saw Lu Xuan's devilish face. He was immediately shocked: "Kunmi? What's wrong?"

Even when Lu Xuan was unhappy, he rarely took his anger out on others. However, at this moment, it was truly difficult for him to suppress all his emotions. He took a deep breath and said, "Nothing. Please stop asking about the Fifth Prince, no, the King of the Northern Territory."

Agamu stared at him blankly: "Why? The King of the North is so close to us..."

Lu Xuan pricked up his ears upon hearing this: "What? What's so close to us?"

Agamu was a little puzzled: "You don't know?"

Lu Xuan clenched his fists: "Stop talking nonsense!"

Aga Mu shrank his neck and said, "The Northern King's fiefdom is... in the north, right in Liang Province. I think there's also Shuofang and... and... where? Oh, Bing Province. I heard these three places are huge! I don't know how big they are, but isn't Liang Province very close to us?"

When Lu Xuan heard that Liu Tan's fiefdom was in Liangzhou, it was as if fireworks exploded in his mind.

Well, because there were no fireworks this year, he only felt dizzy for a moment. The excitement that went from low to high in an instant made it difficult for him to control his expression. He couldn't help but stand up and ask, "Are you serious?"

Aga Mu nodded seriously. "Yes, many people know about it. I heard that it was the King of the North who applied for it himself. He also said that the king is responsible for the country and the prince guards the country. Anyway, people in Chang'an all say that the King of the North is a man of great character."

Lu Xuan didn't say anything else, just looked out the window.

Chang'an, which was about to enter winter, had just lost all its colors in his eyes, but at this moment, he seemed to be in spring with birds singing and flowers blooming.

Even the falling leaves from the trees could not make him feel the desolation of autumn and winter. Instead, he felt that the autumn in Chang'an was amazingly beautiful.

Even though he knew that being sentimental was not a good idea and Liu Tan had never written him a letter anyway, he still couldn't help but think about it. Was Liu Tan's choice of such a fiefdom related to him in some way?

Aga Mu whispered, "Kunmi, can we go see the King of the North when we return?"

Lu Xuan came back to his senses and suddenly remembered that it was already a bit cold in Chang'an. The climate there should be similar to theirs. Maybe it was also very cold?

Moreover, the wind will be very strong in winter, and the resources in the north are not abundant.

Lu Xuan immediately started to worry about Liu Tan suffering there, completely ignoring the fact that the King of the Northern Territory was actually very wealthy and had absolutely everything he needed. Even if the Northern Territory didn't produce any fruits and vegetables, Chang'an would still take the trouble to send them over.

Thinking of this, he wished he could grow wings and fly to the Northern Kingdom. No, no, no, before going to the Northern Kingdom, he had to buy some things to bring over.

Thinking of this, Lu Xuan immediately said, "Ajiamu, Atan must have suffered a lot over there. Before you leave, remember to buy some things for us to bring back to him."

Aga Mu thought about it, nodded seriously and said, "Okay."

With this thought in mind, Lu Xuan wished he could see Liu Che tomorrow and leave the day after tomorrow!

However, how could Liu Che not be proud of capturing the King of Dayuan alive and obtaining the celestial horse? He wanted to hold a grand celebration.

Although it sounds a bit unreasonable to do it just for a few horses, the man has always been in need of good horses, so he can barely have a reason.

Just as Lu Xuan was having a headache looking at the process list in his hand, Liu Che was also having a headache.

When he received Liu Tan's letter, he couldn't help but curse: "You ungrateful little bastard, you still remember to write back!"

Liu Che discovered that whenever he encountered something related to Liu Tan, his self-control would quickly plummet to the bottom. His imperial mentality and his expressionless expression were all fake. No one could remain calm when meeting this guy.

But even so, he still took the letter and took a look at it while cursing.

When Liu Che felt that the letter in the envelope was very thick, he felt a little relieved.

After opening it, he found that Liu Tan directly listed the things he had done after arriving in the Northern Border Kingdom.

Liu Che was stunned, especially after seeing him kill the prefect of Xi'an Yang County, he was still a little bit unconvinced.

Liu Che knew Liu Tan's character very well. Before his transformation, based on the appearance of that playboy, it would not be surprising for him to kill a few people. But after that, Liu Che suspected that Liu Tan would not even dare to kill a rabbit.

Liu Che continued to read. Liu Tan first wrote about the more important events, and then began to describe them in detail.

The reason Liu Tan killed the prefect of Xi'anyang County was simply that he had offended him in the examination room.

At this time, Liu Che already knew what kind of exam Liu Tan had come up with.

If it were someone else, Liu Che would probably have called it nonsense, but when it came to Liu Tan, he didn't even give the deceased Xi'an Yang County prefect a glance, but instead began to study the examination system that Liu Tan had come up with.

After studying it, he found that this examination system was so complete that it did not seem like a new thing.

Liu Che had a very sharp vision. He could see at a glance that many things here had undergone many evolutions. Take cheating for example. When he suddenly saw the word "exam", even he would not think of cheating. However, Liu Tan gave a complete set of procedures to prevent cheating.

This set of procedures made it difficult for him to find any major loopholes for a while.

Liu Che couldn't help but mutter, "Gods actually have to take exams? Aren't they worse than humans?"

After muttering, he continued to read. Below was Liu Tan's application to expand his private army. The reason was very sufficient. He directly listed a series of minerals. He didn't mention coal here.

Because Liu Tan was not sure whether he could dig out coal for Liu Che to use by winter.

Or whether there is enough clean coal.

Ordinary coal can certainly be burned, but it will produce a lot of smoke. If such coal is sent to Liu Che, he will probably beat him up personally.

But even if we don’t count the coal mines, the row of them is shocking enough.

If a place can discover a mineral in a year, it is already a blessing from God, especially a copper mine, so much so that one can't help but offer sacrifices to heaven and earth.

But what about Liu Tan? He simply listed the number of people needed and the number of people he had in a very ordinary tone, and then asked if he could recruit more private soldiers.

Liu Che was so irritated by his indifferent tone that he wanted to beat his chest. It took him a long time to catch his breath. He wanted to continue flipping through the pages, but found that there was no more!

Liu Che looked at the last page in disbelief.

So this letter is all official business from beginning to end?
