Just as Zhou Yu was savoring Sun Ce's words, the Peng official walked out quickly, glanced at Sun Ce deeply, and invited him sideways.

"The prince of the palace invites the two of you to meet in the atrium."

Zhou Yu was a little surprised. He originally thought that Lu Kang would ignore Sun Ce's almost boring question, but he didn't expect Lu Kang to invite them in, and he was so polite that he wanted to meet them in the main court of the Taishou Mansion. Sun Ce was not surprised at all. If Lu Kang still refuses to see them, he is ready to go in. Taishou Mansion is heavily guarded, and he is not alone, so he simply makes a big fuss, he wants to see if Lu Kang dares to arrest him and Zhou Yu.

The two followed the officials to the atrium. Lu Kang sat in the hall, dressed in Confucian clothes, with a roll of bamboo slips in his hand. He was probably in his sixties, of medium height, with a Chinese face, sparse eyebrows, a gray beard, and a very well-groomed man. Although the expression is not severe, it is very solemn, rigid but not fierce, and not angry and arrogant. A group of old and young Confucian scholars sat on the side, looking at Sun Ce and Zhou Yu who walked in, with different expressions, but many people's eyes lit up and cheered for these two beautiful young men. Zhou Yu is also enough, he is the Lujiang family, the well-known son of the turbidity world, Sun Ce is not a cold family in Fuchun, Wujun, the son of a martial artist, and Zhou Yu are not equal, which is also rare.

"I never thought that I would have such a talent among the juniors of Wu County, but unfortunately I have a good skin and a hasty belly." Lu Kang was a little surprised, and he felt sorry in his heart. He bowed slightly, and gestured to a seat that had just been placed beside him. "Sun Jun's question is profound, I can't answer it, and I ask Sun Jun for advice. If it can be said to be reasonable, this seat will be set up for Sun Jun, and Chen Zhongju will be the story of Xu Ruzi. ”

Before the words fell, there were a few exclamations in the seat. Chen Fan is one of the three gentlemen of the party, with an outstanding reputation, Xu Ruzi is a famous scholar in Yuzhang, and is regarded as a model of "outstanding people". Although Lu Kang did not dare to compare with Chen Fan, he imitated his predecessors and treated Sun Ce like this, which also gave Sun Ce enough face, which was enough to deserve the previous contempt.

Of course, this is on the premise that Sun Ce can answer his own questions. If he can't answer, he is just bored with himself, and he can't complain that Lu Kang doesn't give him face. To give you face, you still have to have the ability to hold it.

For a while, countless pairs of eyes fell on Sun Ce's body, and his expression was a little more playful, and even Zhou Yu was a little nervous. Sun Ce's vision has improved, but does he know the answer to this question? If you don't know, it's a bit embarrassing. He quietly tugged at Sun Ce's sleeve and signaled Sun Ce not to act rashly, lest it be difficult to ride a tiger.

Sun Ce raised his eyebrows, and honestly and unceremoniously pulled Zhou Yu over. Zhou Yu was still a little hesitant, but Sun Ce sat down by his shoulder, Sun Ce also lifted the hem of his clothes, knelt down, and couldn't help scolding in his heart. Sit like this...... It's so uncomfortable.

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

Sun Ce calmly asked, "Which heavy heaven does Ming Fujun want to ask?" ”

Lu Kang was stunned for a moment, his curiosity rose, and he said slowly: "Then you might as well talk about this piece of Chutian above our heads." ”

In ancient China, there was a saying that there were nine heavens, but these nine heavens did not refer to the nine heavens wrapped in layers, but to different directions. For example, "Lü's Spring and Autumn Period" said that there are nine fields in the sky, the central is called Juntian, the east is called Cangtian, and the northeast is called Changing Heaven. The north is called Xuantian, the northwest is called Youtian, the west is called Haotian, the southwest is called Zhutian, the south is called Yantian, and the southeast is called Yangtian. The "Huainanzi" of the former Han Dynasty also said that the central is called Juntian, the east is called Cangtian, the northeast is Mintian, the north is Xuantian, the northwest is Youtian, the west is Xiaotian, the southwest is Zhutian, the south is Yantian, and the southeast is Yangtian. With the saying that the sky is round and the earth is round, there is no difference between the distance between the sky and the earth, and it can even be said that there is no definite data. Even if it's the same sky, it depends on where you are, and the distance is naturally different from each other.

When Lu Kang heard Sun Ce's question, he knew that there was no solution to this problem, and he let Sun Ce come in just to kill Sun Ce's sharpness, so that he would not get carried away, thinking that the old man Sun Ce would be presumptuous if he made meritorious contributions. No matter how many military exploits Sun Jian has, no matter how high the official rank, it does not mean that the Sun family has entered the family. Now when he heard Sun Ce ask him which heaven he was going 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 cards not according to the routine. He has a good idea of his own psychology, don't look at his deep knowledge of the history of the Three Kingdoms, if he really wants to quote the scriptures to discuss the meaning of the scriptures, he is absolutely blind. If you want to defeat Lu Kang, you must firmly control the direction of the discussion and beat the master to death.

"What Ming Fujun said about Chutian is a sky of clouds, or a sky of stars, if it is a sky with stars, which sky is where the star is located?"

Lu Kang was stunned again, and he didn't know what to say for a while. "This ...... Is there a difference? ”

"Has the Ming Mansion Jun measured it?"

"Nope."

"How do you know there's no difference if you haven't measured?"

Lu Kang frowned, his face displeased. "Then Sun Jun has measured?"

Sun Ce had already been prepared, and asked rhetorically again, forcing Lu Kang to follow his train of thought. "If I said I measured, would you believe it?"

Lu Kang was speechless. He knew that Fuchun Sun was not a family heirloom with knowledge, although Sun Ce had read books, but he had not worshiped a famous teacher, at best, he knew a few words, understood a few scriptures, and he had enough confidence to deal with him, so he let Sun Ce come in, and wanted Sun Ce to see what real learning is. Unexpectedly, Sun Ce was aggressive as soon as he entered the door, and asked several questions, which were always unexpected by him, which caught him off guard.

"I can't believe what Sun Jun says." Lu Kang forced himself to calm down and sneered at each other.

"That's right, whether I've measured it or not, Ming Fujun doesn't believe it, right?" Sun Ce smiled slightly, taking retreat as advance. "In that case, I told Ming Fujun how to measure, and Ming Fujun asked for the answer himself, what does Ming Fujun think?"

Lu Kang sneered: "The method you said is probably not more than nine chapters or anything like that, right?" I don't need to say this, I will. I just want to know, even if you can calculate the height of the sky with these methods, how can you calculate the thickness of the earth? ”

"Nine Chapters of Arithmetic" has been completed in the Han Dynasty, and it has become the most important one of the ten books of arithmetic, and many times it is synonymous with arithmetic, and Lu Kang naturally knows it. In his opinion, the method Sun Ce said was nothing more than algorithms such as Fang Tian and Shaoguang in the Arithmetic. Those algorithms can indeed calculate the distance, and theoretically they can also calculate the height of the sky, but how do you calculate the thickness of the ground?

Lu Kang's rhetorical question was very sharp, avoiding further entanglement with Sun Ce on the question of how high the sky was, and pointed to the point.

"If you know the height of the sky, you will naturally know the thickness of the earth." Sun Ce sighed lightly: "However, if you hold the outdated old theory that the sky is round and the place is round, then you can't talk about it." Mingfujun, let me take the liberty of asking, have you ever heard of the Hun Tian theory of Nanyang sage Zhang Heng and Zhang Pingzi? ”

Lu Kang hesitated for a while. "Do you mean, 'The sky is like a chicken, and the earth is like a rooster among the yellow'? I've heard of it, but I haven't done any research, so I don't dare say it. He glanced at Sun Ce with some reluctance. Is Sun Jun familiar with Zhang Pingzi's doctrine? Can you explain a story or two? ”

Sun Ce crooked his mouth and smiled meaningfully. "You haven't studied it, what did I say, do you know if it's true or not?"

Lu Kang's face was a little distorted, this was too hurtful. You don't understand what I'm saying, so what else is there to say. Lu Kang is almost old, and it is the first time that he has been despised by a young man in person, and this young man is still a martial artist who does not learn or know.

Sun Ce sighed regretfully, and then said, "Since Ming Fujun is not very familiar with the way of heaven and earth, then I will change to a simpler question. Master Zeng Yun: Repay grievances with directness, and repay virtue with virtue. Dare to ask Ming Fujun, has the master ever said that he will repay virtue with grievances? ”

There was a dead silence in the hall, some of the people looked at each other, some stammered, and some stood up, glaring at Sun Ce angrily, eager to eat him alive.

Zhou Yu sighed in his heart. After going around for a long time, Sun Ce still came to slap his face. After so much foreshadowing, all I have to hear is this last sound.
