After many ineffective protests, Liu Chang gradually got used to the daily reading routine in Tianlu Pavilion.

The course gradually became more and more inscrutable, and many people thought that the philosophy of that era was just like that in later generations, and it was not difficult at all, but in fact, anyone who had carefully read any of the classics of that era could feel that great difficulty.

I don't know how many writers who have made up their minds to write 5 million words of pre-Qin novels have given up after countless nights of reading pre-Qin classics and pulling off their few hairs.

Liu Chang was even more so, he couldn't understand what the teacher was saying at all.

"In the first month of Meng Chun, the position of the sun is in the camp room... At the beginning of dusk, Betelgeuse appeared in the southern mid-heaven.... At dawn, Ojuku appears in the southern midten. Meng Chun belongs to Jia and B in the Heavenly Stem, its dominant emperor is Taihui, the god of Emperor Zuo is Jumang, and its seasonal animals are scale tribes such as Arowana..."

"If the decree that should be issued in the summer is issued in the first month of Meng Chun, then the wind and rain will not come and go normally, the grass and trees will wither prematurely, and the people will be terrified."

"If it is published in the autumn, then the people will suffer from the epidemic, the storm will hit many times, and the weeds will grow."

"If a decree is issued that should be issued in winter, then the flood will destroy life, the frost and snow will seriously damage the crops, and the wheat will not be able to produce a harvest."

"What?? What the hell is this?? ”

Liu Chang also tried it, and he once asked the teacher, what is the decree that should be issued in winter?

"Ordered the officials in charge to hold large-scale sacrifices, and the four gates of the city were slaughtered and sacrificed, and local cattle were made to send the air of winter. Birds that fly far away fly high and fast, and worship the gods of mountains and rivers and the gods of heaven and earth who have contributed to the people..."

"If the decree of the winter season is carried out in the autumn, then the white dew will fall prematurely, and the crustacean animals will be plagued..."

"Forget it, forget it, teacher, you go ahead and talk about your..."

But it's such a thing, the rest of the guys listened to it with relish, and Liu Chang didn't know if they were pretending to be interested or really interested in these things that the gods were chattering, anyway, he was not interested at all, and his daily classes were used to make up for sleep.

Just when the teacher finished a class and was about to drink water and rest, Liu Ruyi slowly walked into the Tianlu Pavilion.

At this moment, he was still wearing the same clothes that he had just gone to the court, which was very luxurious, and I saw him solemnly walk to the side of his brothers, lowered his head, looked at the books on their desks, and nodded, "Yes, you must study hard, so that you can better govern the place in the future..."

Liu Chang looked at the serious Liu Ruyi in surprise, and couldn't help but ask Liu Hui beside him, "What kind of evil did he fall into?" ”

"I heard that I went to the court as a prince and king..."

"Oh..."

Although no one asked, Liu Ruyi still boasted about his participation in the court discussion, and he deliberately pretended to be that kind of adult, as if he was different from these little brothers now, and he was already a prince of the Han Dynasty.

"Chief, you really did a good thing this time, the prime minister has already said, let's promote the spinning wheel in our own feudal country..."

"You can pull it down... Return your feudal country, do you know where the city gate of Handan opens? ”

Liu Chang complained in a low voice, but he was really curious about how the big man used the spinning wheel, so he didn't interrupt Liu Ruyi.

Liu Ruyi deliberately hung him, saying that Xiao He had his own arrangements, but he didn't say how he arranged them.

Liu Chang's face became darker and darker, and just when he was about to give up, Liu Ruyi finally said Xiao He's series of arrangements, I have to say, Liu Ruyi's brain is still okay, what Xiao He said, he can recite it intact, and his memory is good.

As for Xiao He's arrangement, Liu Chang was also surprised.

He found that the fierce people of this era are really fierce, and it has been less than a month since he made the spinning wheel, Xiao He has already made a decision, and by the way, he has also made a lot of spinning wheels... What kind of efficiency is this, Liu Chang feels that compared to the efficiency of the spinning wheel, the efficiency of this prime minister seems to be more terrifying.

"You have a long face this time, even the King of Chu and the King of Jing are full of praise for you, and they also say that they will give you a special reward for your contribution to their country!"

"Then what reward does King Zhao have for the grass people? The people of Zhao have benefited a lot because of me, don't you, the king of Zhao, also have something to reward? ”

Liu Ruyi was speechless for a moment, his face turned red, he reluctantly picked up the saber, put down the saber, picked up the saber again, and put down the saber again...

"Hey, forget it, forget it, I'll reward it when you return to the feudal country!"

Liu Chang was very happy, not because of the words of King Chu and King Jing, but because of Xiao He's arrangement, he was originally worried that the spinning wheel would not play any role after it was made. But if you want to let Liu Chang arrange it himself, it will be a little unreliable, and letting a doll make decisions about governing the country is the same as asking a student of history to write an online article, which is unreliable, and it is easy to hit the street.

Now, Liu Chang is not worried, there is such a fierce man, no matter what machine he makes, he must be able to arrange it.

Liu Chang and Liu Ruyi were very happy, but Liu Heng looked a little worried, and he asked Liu Ruyi again and again, "Is King Yan really not coming?" ”

"It's that I didn't come, I haven't seen King Yan for a long time..."

"Father didn't mention him?"

"Nope..."

"Father didn't mention King Yan but mentioned Zhao Xiang?"

"Hmm."

Liu Heng frowned, not knowing what he was thinking.

At the end of the course, when Liu Chang was about to leave, Liu Heng suddenly followed him, Liu Chang felt a little strange, but he didn't say anything, just when Liu Chang parted ways with him, Liu Heng grabbed Liu Chang, Liu Chang was stunned, "Fourth brother? I've sent the handsaw back..."

"Long. Don't go to the Marquis of Huaiyin, follow me to the craftsmen. ”

"If you don't go, you can't do it, if you go late, you'll be beaten, and if you skip school, it's over..."

Liu Heng was silent for a moment, and then said: "Then come back early, find me when you come back, and I'll take you to Changle Palace for a spin." ”

"Good!"

Liu Chang left happily, Liu Heng looked at his distant back, frowned, and stopped talking.

Liu Chang didn't take this little episode to heart, but after coming to Han Xin's mansion, Liu Chang felt a little confused. He had seen Han Xin's angry and irritable appearance, but he had never seen Master so absent-minded.

Since the last time I chatted with Master, the difficulty of his courses has skyrocketed, which is a headache, but Liu Chang has learned well, after all, many questions are related to mathematics. But today, Han Xin was always distracted, and as he spoke, he fell silent and began to be in a daze.

Moreover, the fierce man who always stood outside the house was gone.

Liu Chang asked, Han Xin just said that he went to buy the things he needed in the house, but on weekdays, things like buying things were not done by Gu Lai at all.

Master's state is very wrong, hesitating? Worry? Agitated? Liu Chang couldn't see it.

"Master... Are you okay? Is it sick? ”

Liu Chang looked at Han Xin in front of him worriedly, in this era, getting sick is basically being sentenced to death, and medical technology is not developed, even if you are a prince and nobleman, you can't escape. Some minor ailments, which were very common in later generations, can be fatal in this era. Han Xin's face looked very bad, his eyes were extremely heavy, and his eyes were bloodshot.

Liu Chang's inquiry seemed to wake up Han Xin, who went outside to wash his face and came back soon.

He began to teach again, in the same state as before, except that his tone was much colder, no invective, no anger. When Gu returned to the mansion panting, Han Xin suddenly ended his teaching and asked Liu Chang to go back early.

Liu Chang only felt a little inexplicable, but he still left.

He felt that something must have happened, but what else could happen to Han Shin now? He is in the capital, although Liu Bang gave him a certain amount of freedom, but he can't go out of the city, and he can't order anyone, in other words, he is just under house arrest in the capital, what can happen?

Thinking of the fourth brother suddenly stopping himself, Liu Chang couldn't help but guess, could it be that the fourth brother knew about this?

Thinking of this, Liu Chang hurriedly galloped towards the palace, he was going to find the fourth brother and ask for an understanding!
