Just as Zhou Yu was savoring Sun Ce's words, the clerk walked out quickly again, looked at Sun Ce deeply, and invited him sideways.

"The Lord of the House invites the two of you to meet in the atrium."

Zhou Yu was quite surprised. He thought Lu Kang would ignore Sun Ce's almost boring problem, but he didn't expect Lu Kang to invite them in, and he was so polite to see them in the main court of the prefect's palace. Sun Ce was not surprised at all. If Lu Kang refused to see them, he was going to go in. The prefect's palace was very cautious and he was not alone, so he just made a big fuss. He wanted to see if Lu Kang dared to arrest him and Zhou Yu.

The two followed the clerk to the atrium. Lu Kang sat in the hall, wearing Confucian uniforms, with a roll of bamboo slips on his hand. He was about sixty years old, with a medium figure, a national face, sparse eyebrows and bright eyes, and a white beard. He was very careful. Although his expression was not strict, he was very solemn, strong but not fierce, and he was powerful without anger. A group of Confucian scholars, both old and young, sat aside, looking at Sun Ce and Zhou Yu who came in, with different expressions, but many people's eyes lit up, applauding these two graceful young men. It was fine, Zhou Yu, he was a well-known young man in the Lujiang clan, and was a good son of a turbid world. Sun Ce was just a poor family in Fuchun, Wujun, and a son of a martial artist. It was rare to walk with Zhou Yu without being in the same direction.

"I never thought that my juniors in Wujun were such talented, but unfortunately I had a good face and had a cub in my belly." Lu Kang was a little surprised and felt regretful. He bowed slightly to repay the gift and pointed to a seat just placed beside him. "Mr. Sun's question is profound, I can't answer it, so I would like to ask Mr. Sun for advice. If it can be explained, this seat will be set up for Mr. Sun, and follow Chen Zhongju as the story of Xu Ruzi."

Before he finished speaking, there were several exclamations in the seat. Chen Fan was one of the three party members and had a great reputation. Xu Ruzi was a famous scholar in Yuzhang and was regarded as a model of "arewell people". Everyone knew the story of Chen Fan setting up a special seat for Xu Ruzi, and it has always been a good story in the scholars. Although Lu Kang did not dare to compare with Chen Fan, he imitated his predecessors and treated Sun Ce in this way, which gave Sun Ce enough face, which was enough to deserve the previous contemptuous mistakes.

Of course, this is the premise that Sun Ce can answer the questions he raised. If he can't answer them, he will be bored and he will be unresponsive to Lu Kang for not giving him face. Giving you a face, you still have to have the ability to protect him.

For a moment, countless pairs of eyes fell on Sun Ce's body, and his expression became more interesting. Even Zhou Yu became a little nervous. Sun Ce's vision improved, but did he know the answer to this question? If he didn't know, it would be a bit embarrassing. He quietly pulled Sun Ce's sleeve and signaled Sun Ce not to act rashly, so as not to get out of trouble.

Sun Ce raised his eyebrows and pulled Zhou Yu over honestly and unceremoniously. Zhou Yu was still hesitant, but Sun Ce sat down with his shoulder. Sun Ce also lifted up his clothes and knelt down. He couldn't help but curse in his heart. Sitting like this... It's so uncomfortable.

Lu Kang turned his head and looked at Sun Ce quietly, but he chuckled in his heart: Childish! I'm afraid it's easy for you to sit down, but it's difficult to stand up.

Sun Ce asked calmly: "My Lord of Mingfu wants to ask which level of heaven?"

Lu Kang was stunned for a moment, curiosity arises, and he slowly said, "Then you might as well talk about the Chutian above our heads."

There was a saying of the Nine Heavens in ancient China, but these Nine Heavens do not refer to the nine layers wrapped in layers, but to different directions. For example, in "Lüshi Chunqiu", it says that there are nine fields in the sky, the center is called Juntian, the east is called Cangtian, and the northeast is called Biantian. The north is called Xuantian, the northwest is called Youtian, the west is called Haotian, the southwest is called Zhutian, the southwest is called Yantian, and the southeast is called Yangtian. The "Huainanzi" of the former Han Dynasty also says that the center is called Juntian, the east is called Cangtian, the northeast is called Mintian, the northeast is called Mintian, the northwest is Yuetian, the northwest is Youtian, the west is called Wutian, the southwest is called Zhutian, the southwest is called Yangtian, the northwest is called Yutian, the northwest is called Yutian, the west is called Yutian, the southwest is called Zhutian, the southwest is called Yangtian, the southwest is called Yangtian, the southwest is called Yangtian. In line with the theory of the round and earth, there is no difference between the distance between the heaven and the earth, and it can even be said that there is no definite data. Even the same sky depends on where you are. The location is different, and the distance naturally does not last.

When Lu Kang heard Sun Ce's question, he knew that the problem was unsolvable. He asked Sun Ce to come in just to kill Sun Ce's spirit, so that he would not be proud of himself, thinking that Sun Jian could be arrogant if he made a contribution. No matter how many military achievements Sun Jian has, no matter how high his official title, it does not mean that the Sun family has entered the aristocratic family. Now when he heard Sun Ce ask him which heaven he wanted to ask, he suddenly realized that Sun Ce was not just trying to make things difficult for him, he seemed to really know the answer.

Sun Ce successfully seized the initiative and continued to play according to routines. He had a clear idea of ​​his own mind. Although he had a deep understanding of the history of the Three Kingdoms, he would definitely be blind to the classics if he really wanted to quote the classics and discuss the meaning of the classics. If he wanted to defeat Lu Kang, he had to firmly control the direction of the discussion and beat the master to death.

"The Chutian that the king of Mingfu mentioned is the sky with clouds or the sky with stars. If it is the sky with stars, which star is the sky where the star is?"

Lu Kang was stunned again, not knowing what to say for a moment. "Is there a difference...?"

"Have you ever considered me in Mingfu?"

"No."

"I haven't measured it, how do you know there is no difference?"

Lu Kang frowned and looked unhappy. "Will Mr. Sun consider it?"

Sun Ce was prepared and asked again, forcing Lu Kang to follow his thoughts. "If I had said that I had measured it, would you believe it?"

Lu Kang was speechless. He knew that Fuchun Sun family did not pass on their knowledge. Although Sun Ce had read books, he had never been a famous teacher. At best, he could only recognize a few words and interpret a few sentences of scriptures. He had enough confidence to deal with him, so he let Sun Ce come in, hoping that Sun Ce would see what real knowledge was. Unexpectedly, when Sun Ce entered the door, he was aggressive and asked several questions in a row, which always caught him off guard if he was unexpected.

"I can't believe whatever Sun Jun said." Lu Kang forced himself to calm down and retorted.

"Yes, whether I have measured it or not, the Mingfu Jun will not believe it, right?" Sun Ce smiled slightly and took retreat as an advance. "Since that's the case, I will tell the Mingfu Jun how to measure it. The Mingfu Jun will ask for the answer by himself. What does the Mingfu Jun think?"

Lu Kang sneered: "The method you mentioned is probably not like Jiuzhang or something? I don't need to say this, so do I. I just want to know, even if you can use these methods to calculate the height of the sky, how can you calculate the thickness of the earth?"

"Nine Chapters of Arithmetic" was completed in the Han Dynasty and became the most important one among the ten books on the calculation of classics. It is often synonymous with the calculation of classics, and Lu Kang naturally knew it. In his opinion, the method Sun Ce mentioned was nothing more than algorithms such as square fields and Shaoguang in the classics. Those algorithms can indeed calculate distance, and theoretically they can also calculate the sky high, but how do you calculate the thickness of the earth?

Lu Kang's rhetorical question was very sharp, avoiding further entanglement with Sun Ce on the question of how high the sky is, and directly pointing to the key points.

"If you know that the sky is high, you will naturally know that the earth is thick." Sun Ce sighed softly: "However, if you hold an old saying of the world that is round and the place is outdated, you can't talk about it. Mingfu Jun, I'll ask, have you heard of the Huntian sayings of the ancestor Zhang Heng and Zhang Pingzi of Nanyang?"

Lu Kang hesitated for a while. "Are you saying 'The sky is like a chicken, and the ground is like a yellow in a chicken'? I have heard of it, but I have never done any research and dare not speak nonsense." He glanced at Sun Ce with some reluctance. "Is Sun Jun familiar with Zhang Pingzi's theory? Can you explain it one or two?"

Sun Ce tilted his mouth and smiled meaningfully. "You haven't studied it yet. What do I say? Do you know whether it's true or not?"

Lu Kang's face is a little distorted, and this is so hurtful. You don't understand what I said, so what else can I say? Lu Kang is nearly 70 years old and is the first time he has been despised by a young man in person. Moreover, this young man is still an ignorant martial artist.

Sun Ce sighed regretfully, and then said, "Since the Lord of Mingfu is not very familiar with the way of heaven and earth, then I'll change to a simple question. The Master once said: Repay evil with righteousness and virtue with virtue. How dare you ask the Lord of Mingfu, did the Master of Mingfu say that he repays kindness with evil?"

The hall was silent. Some of them looked at each other, some were speechless, and some were raised up, glaring at Sun Ce, wishing they could swallow him alive.

Zhou Yu sighed in his heart. After wandering around for a long time, Sun Ce still came to slap in the face. After so many preparations, all he had to hear was the last sound.
