When Liu Tan received the reward from Liu Che, his right eyelid twitched and he couldn't help touching his eyes.

Huo Guang noticed his movements and asked, "Your Highness, are you feeling unwell?"

Liu Tan shook his head. "Nothing. My right eyelid twitched a little. Maybe I've been too tired lately."

Huo Guang became alert: "Your right eye is twitching. Your Highness should be more careful these days."

Liu Tan: ...

Scientific education is imperative!

He didn't take it seriously, and happily took the letter and said, "Father has already had the Northern Plow made and tested."

Even though Huo Guang was always reserved, he couldn't help but smile and said, "Your Majesty must be very happy."

After reading the letter, Liu Tan looked up at Huo Guang and said, "I am very happy. I am so happy that I won't be making an eastern tour this year."

Huo Guang was slightly stunned. "What? No more eastern tour? But... another Taoist priest has come to Your Majesty's side?"

Every year during his eastern tour, Emperor Liu Che would either offer sacrifices to the gods at Mount Tai or go out to sea in search of immortals.

In recent years, the Han Dynasty entered a stable period and did not experience many major wars, so naturally there were not many martial arts. Liu Che had no excuse to offer sacrifices to the gods, so most of them went directly to look for immortals.

But now he doesn't even go to look for immortals, so it is very likely that another alchemist has pointed out a new direction for the emperor.

Liu Tan shook his head: "Probably not. Father said he wants to come to our place to escape the summer heat!"

Although it was quite troublesome for Liu Che to come, Liu Tan was still very happy. The weather had warmed up recently, and many wanderers and the like had come to Shuofang City. As far as he knew, places where the emperor often went would indeed be better developed and have more people.

It is quite cost-effective to spend a little money to entertain Liu Che and then use the emperor's reputation to attract people.

Huo Guang never expected that the emperor would give up going out to sea to search for immortals and instead go to the northern border country to escape the summer heat. For a moment, he didn't know what to say.

Should we say that Liu Tan was favored enough to make Liu Che let go of his obsession with immortals, or should we say that Your Majesty must have misunderstood something?

Before, he had always thought that the legend of the immortal Liu Tan descending to earth only existed among the common people, but now it seems that their emperor might also think so.

Going out to sea to search for immortals may not necessarily lead to finding them, but there is a little immortal by their side. Although this little immortal is unreliable, it is precisely because of this unreliability that they can find some clues.

Huo Guang took a deep look at Liu Tan, who was still happy, and for a moment he didn't know whether to tell him about this matter, but this was just his guess. After thinking about it, he decided not to tell him.

Liu Tan's task today was probably to read letters. After reading Chen Ajiao's letter, he couldn't help but sigh and said, "I don't know if the Queen Mother can come."

Huo Guang paused and said, "Why not... ask His Majesty?"

Liu Tan pondered for a while and finally shook his head: "Forget it, it's best not to get involved in the affairs between my father, the emperor, and my mother."

The relationship between these two people was too complicated. When they were young, they almost became enemies. Liu Che was determined to depose the queen, and Chen Ajiao was determined to have a prince son.

Now the two of them seem to have calmed down a lot. One doesn't want to depose the queen anymore, and the other... well, it's hard to say, maybe he still wants Liu Tan to be the crown prince. There is a delicate balance between them now, but this balance is too fragile, and Liu Tan dare not break it easily.

Liu Che probably wanted to relax when he went on the trip, and he certainly wouldn't want to bring a woman who always caused him trouble.

Thinking of this, Liu Tan suddenly touched his chin and said, "I don't know what happened to the Hu Ji that my father took away before."

Before, Liu Che took away three Hu girls from the tavern at once, but in fact only one of them was favored by the emperor, so when Liu Che left, he only took away the most beautiful one, and the remaining two were left to Liu Tan.

Liu Tan had a terrible headache at the time. After much thought, he decided to hand the two Hu girls over to Huo Guang for disposal. Otherwise, he was afraid that Lu Xuan would come back and see the Hu girls still with him. Then he would be filled with jealousy instead of jealousy.

Huo Guang raised his eyebrows and looked at him: "Didn't my wife scold you?"

Liu Tan also felt strange: "Yeah, no one mentioned it."

It's so strange. Liu Che took the woman back from him, but Chen Ajiao didn't react at all. Even if she didn't make trouble with Liu Che, she would have written a letter to him, right?

Huo Guang said calmly: "Oh, then it might mean being alive."

Liu Tan was about to say, "Why are you talking nonsense?" Of course I know she's alive.

But he soon realized that what Huo Guang meant was that this Hu Ji was just living a stable life in the harem, and there might not be anything else like Lady Li or Lady Gouyi, who were given status, position and favor when they were brought back.

Maybe that's why Chen Ajiao didn't feel threatened and just pretended she didn't exist?

This is very possible. Liu Tan couldn't help but sigh: Liu Che is such a pig.

He continued to read the letter and found that there was another letter written to him by Princess Dangli. When he opened it, he found that Princess Dangli generously stated that she would give him a cart of salt every month.

Liu Tan was stunned for a moment, then looked up at Huo Guang and asked, "Did Princess Dangli also send something?"

Speaking of this, Huo Guang was quite amused and said, "It's a cart of salt."

Liu Tan's mouth twitched. "She also has to deliver salt every month, from Dangli to the northern border. She's not afraid of the trouble!"

Huo Guang said, "That's how she is."

She is willful, extremely willful. She has been better in recent years because of the twists and turns in her marriage. But before she got married, Princess Dangli was definitely someone who could not be provoked in Chang'an City.

However, she also has the right to be willful.

After gossiping with Huo Guang for a while, Liu Tan asked, "I heard that the emperor sent people to select high-quality breeds. What are they?"

Huo Guang said, "I've seen that the main crops are spring soybeans. Your Majesty must have sent someone to check. The main food in the Northern Border is soybeans, with some millet as the remainder. However, the climate in the Northern Border may not be particularly suitable for millet, so the yield is average."

He couldn't help but sigh at this point and said, "Just planting soybeans won't work."

Nowadays, very little grain is sold across regions. Most of it is stored as important materials, on the one hand for military supplies and on the other hand for food reserves. Only with sufficient preparations can we rescue the victims when disaster strikes.

The Northern Border Country has little rainfall and many places are not close to the Yellow River, so what needs to be guarded against is drought.

Liu Tan was a little confused: "Why not?"

"Soybeans aren't considered a mainstream food, after all, and eating too much can have some negative effects on the human body. Ultimately, we'll have to grow some millet."

Liu Tan frowned and said, "If we forcefully plant something unsuitable, the yield will naturally not increase. Can't we buy it from other places?"

Huo Guang looked at Liu Tan calmly and said, "Your Highness, transportation and money are both problems. Even if we buy at a high price, it would be better for us to grow it ourselves."

Liu Tan asked, "What about exchanging it for soybeans?"

Huo Guang gave him a blank look and said, "Where do you think there's a shortage of soybeans? The soybeans grown around the Huai River are even better quality."

Liu Tan suddenly realized, yes, Shandong soybeans were quite famous in later generations.

Neither this nor that works... The only way seems to be to create more economic benefits using soybeans, so as to make up for the price difference of "imported" grain.

The King of Huainan once made tofu from soybeans, but tofu was not a necessity for the people.

He narrowed his eyes and said, "Find me some soybeans."

Huo Guang knew from his expression that he was going to cause trouble again, and couldn't help asking, "What is your Highness going to do?"

Liu Tan smiled but said nothing. What else could he do? Soybean oil!
