Liu Che often doubted whether Liu Tan knew what he was thinking, so he always made choices that were completely different from his ideas.

Liu Che took a deep breath, calmed himself down and then read on carefully. He originally wanted to see what kind of new plow Liu Tan had made. Liu Che had no doubt about the function of the new plow. After all, according to his son's habit, he would not announce it to the world unless it was really well made.

As a result, after he continued to read, he found that Liu Tan did not write how the new plow was made. He simply said that a formal document had been written.

This means that if Liu Che wants to know, he should read the official documents.

Liu Che: ...

For a moment, he was actually confused about whether to read the official document or the letter first!

Fortunately, it was only a moment. He continued to read the letter, and then found that there was nothing more to read. Liu Tan simply talked about the situation in the Northern Border Kingdom after Liu Che left, and by the way, he also lamented that the snow that had surprised them before had turned into a disaster.

But he soon said proudly that the victims had been resettled. There were losses, but they were under control.

Liu Che looked at all this with both satisfaction and dissatisfaction. He really hoped that Liu Tan could govern the Northern Border Kingdom well. If the Northern Border Kingdom was stabilized, it would be more difficult for the Huns to invade the south, and the Han Dynasty would have more breathing space.

But what he wanted to see more was Liu Tan talking about what he had done, rather than focusing on these things.

When this part came to an end, Liu Che had a premonition that his son would probably file a complaint again.

Anyway, every time Liu Tan wrote to him, it was basically accompanied by a complaint. Sometimes, even if it didn't seem like a complaint, the effect was almost the same.

He was still wondering which official under his command would be the defendant this time, but his expression changed as he watched.

He also didn't expect that Liu Tan was suing King Yan Liu Dan this time.

Liu Tan listed all the evidence clearly in the letter, fearing that Liu Che would not believe it.

In fact, when Liu Che saw Liu Tan mention the King of Yan, he had no intention of doubting it.

He knew this son too well. He did not interact with his brothers easily. Moreover, Liu Dan had been enfeoffed early, and he did not have much contact with Liu Dan. If it were not for the conclusive evidence that made him unbearable, he would not have written directly to him.

After reading it, Liu Che narrowed his eyes and turned around and said, "Go ask the King of Yan what he is doing recently."

As for who to ask...it is naturally the embroidered robe envoy in charge of Yan State.

Asking also takes time, and Liu Che continued to read while waiting.

Liu Tan finished his complaint with great confidence and turned to ask, "Father, will you come to the northern border to escape the heat during the height of summer?"

When Liu Che saw this, his previous unhappiness immediately disappeared. He remembered that he had casually mentioned before that he would go to the Northern Border Kingdom to escape the summer heat. He didn't expect that this little guy would take it seriously.

Liu Che glanced at the perpetual calendar next to him, which not only had the date but also recorded some things that needed to be done.

He looked at it and drew a circle on the summer solstice. The summer solstice was a major festival, and he had to preside over a sacrifice on that day. There were no major activities after the summer solstice. In the past, Liu Che would also set out on his eastern tour at this time.

But this year... he wants to change places.

Just as Liu Che was thinking about his travel plans, Crown Prince Liu Ju finished his own affairs and came to report to his father.

After paying his respects, Liu Che asked, "Did Tan'er write you a letter?"

Liu Ju automatically pulled out a few pieces of letter paper and said, "I've written it."

Liu Che was very satisfied with his understanding. He picked up the paper and found that there was not much on it. After looking carefully, he found that it mentioned the Lantern Festival or something like that. By the way, he also invited Liu Ju to spend the summer there to escape the heat.

Liu Ju was very excited. He came here just to ask his father if he could go to the Northern Border Country for a trip.

After reading it, Liu Che put down the letter and said, "I plan to go directly to the Northern Border Kingdom this year."

Liu Ju suddenly had a bad feeling in his heart: "Is the emperor not going on tour to the east?"

Liu Che was somewhat disillusioned. "I haven't heard of any news of immortals appearing in the world for a year. It would be better to go to the northern border."

It's not that there was no news, but Liu Che, who had been trained by Liu Tan, was more or less able to distinguish those lies. Liu Tan had demonstrated many things to him on the spot, and those people still wanted to use them to deceive him. The result was naturally imaginable.

In particular, the eastern tour would inevitably pass through Changyi and Qi. The contrast with last year was too obvious, which made Liu Che unwilling to go there again.

As if remembering something, he suddenly asked, "Any news of coal being found in Qi or Changyi?"

Liu Ju shook his head: "No, it is said that the King of Changyi and the King of Qi have decided to suspend their search."

Liu Che's face darkened: "Could it be that they still think Tan'er is lying?"

Liu Ju deliberately said, "After such a long time without finding it, the King of Qi and the King of Changyi must have become discouraged."

Liu Che snorted, "Back then, Tan'er had to go through great pains to find me. Who do they think they are?"

Liu Tan did not spend long searching, but Liu Che always thought that Liu Tan knew roughly the right place. Even so, it took him some time, not to mention that Qi and Changyi did not know the exact location at all, so it would naturally take longer.

Liu Ju thought to himself, "This... can't be blamed on the Second Prince. They don't have any veterans under their command, so they might not even recognize coal if they saw it. I remember my younger brother mentioned sending people to look for it, but it seems the Second Prince refused. After all this time, all this time, all this time spent on manpower and resources, and nothing to show for it, they're naturally discouraged."

Liu Che's expression turned even colder as he said, "It's a pity that Qi is too far away from the northern border."

Liu Ju's mind moved. When Liu Che said this, he knew that his father must be thinking of giving Qi and even Changyi to Liu Tan.

As for the King of Qi and the King of Changyi...it's too easy to settle them, just change their titles directly.

Unfortunately, as Liu Che said, the two places are too far apart, and the current Northern Border Kingdom cannot do without Liu Tan.

Apart from anything else, as long as Liu Tan is there, Wu Shilu will be wary, not to mention that he still needs Liu Tan to restrain the King of Wusun.

Liu Ju also sighed. The northern border country had a bad climate and was poor, and the Huns were eyeing it covetously. His brother was almost playing tricks on him. If Qi State gave it to him... how would it develop?

He thought of this and said, "It's a bit far, but the climate in the Northern Territory is not good. Qi can be left for my younger brother to live in in his old age."

It is not impossible to change the title. After the Northern Border Kingdom stabilizes, Liu Tan will be transferred to Qi.

No matter what, Qi is always better than the northern border country.

Liu Che laughed after hearing this: "You are really good at considering him, but he may not think that far ahead."

Liu Ju smiled and was about to explain something when he saw an envoy in embroidered clothes coming in with a scroll in his hand.

Liu Ju decisively shut his mouth and sat in his seat as if he didn't exist.

The smile on Liu Che's face faded and he asked, "How is it?"

The embroidered messenger knelt on one knee, held the scroll in both hands and presented it, saying, "Your Majesty, the King of Yan has been here recently, and his condition is no different from before."

The envoy in embroidered robes was a little nervous. It was actually very easy for him to be in charge of Prince Yan because the emperor was not particularly concerned.

Or it could be said that among all the embroidered robe envoys in charge of the princes, only the one in charge of the King of the North was the busiest. Some people gloated over this busyness, while others envied it.

The emperor's attention means that the embroidered robes messenger will appear before the emperor more often. This kind of thing has always been a double-edged sword. A careless word may anger the emperor or leave a deep impression on him, so that he will think of it first when something happens in the future.

Of course, the embroidered envoy did not dare to hide the matter for Prince Yan. He thought about it in his mind and did not find any special behavior of Prince Yan recently. He was quite frightened for a moment.

Especially since he had just taken a quick glance at Liu Che's expression, he felt that something bad was going to happen to Prince Yan.

At this time, Liu Che was indeed unhappy. There was not much written on the scroll. It was not detailed enough to record the three meals a day of the Prince of Yan. But even so, it was written that the Prince of Yan went out frequently, either to brothels or to manors for fun. Even if he did not go out, he would listen to songs and enjoy dances all day long, and sometimes he would meet with the scholars he recruited.

However, this meeting was basically a one-sided meeting of the literati praising the King of Yan. Writing lyrics and essays were the most basic, and whoever wrote better would receive a reward.

In addition to this, there is the Prince of Yan's wonderful private life. Group sex is a common phenomenon, and not only does it involve both men and women, but sometimes there are even both men and women present, which is simply outrageous.

The more Liu Che looked at it, the angrier he became. The contrast was too obvious.

The younger brother has been working diligently in the Northern Border Kingdom. Recently, he has been busy making new plows or digging lakes and building dams. In the process, he also invented the kang and cared about the lives of ordinary people. The only time he had a holiday was during the New Year, when he played with the King of Wusun all day long.

After the New Year, the daily entertainment activity was just to play with Gun Gun for a while, and this period of time was extremely short. The rest of the time was spent eating and sleeping. Even Liu Che felt a little distressed when he saw that time arrangement.

As a result, his elder brother was so foolish that he didn't even realize that someone was smuggling ironware out of his country, and he lived a life of luxury every day. In addition, the King of Yan had hoped to change his fiefdom more than once before. In contrast, Liu Tan took the initiative to go to the Northern Border Kingdom to share his father's worries.

The more Liu Che thought about it, the angrier he became. If Liu Dan were in front of him, he would probably whip his son a few times.

Think about the King of Qi and the King of Changyi again. They are both his sons, so why is there such a big difference between them?

After reading the scroll, Liu Che's face successfully evolved into a living devil. All the palace maids and embroidered robe messengers dared not breathe, and even Bu Fan did not dare to say a word.

Liu Ju secretly observed his father's expression. Although he didn't know what had happened, after analyzing it in his mind, he felt that his father was not angry with him and Liu Tan, so there was nothing more to say.

Liu Ju said, "Father, I heard that you prepared farm tools and good seeds for my younger brother. My sister asked when we would set out."

Liu Ju's expression suddenly became a little subtle: "No need."

Liu Ju's heart sank, and he asked carefully, "What's wrong? Did my brother make you angry? He's a straightforward person, so don't bother with him."

Liu Ju glanced at him sideways and said, "Your brother has grown stronger and has invented a new plow. He's named it the Northern Plow and it's said to be very useful. You can ask the Minister of Agriculture to make a few for us to see later."

Liu Ju: ???
