Generally speaking, the imperial examination rarely involves the debate among saints, and most of the holy words are just common sense.

However, this year's children's test has a topic involving the dispute over the holy way. I don't know what the saints mean.

Fang Yun didn't think much when answering the question, but now he has extra energy and falls into thinking.

The content of the imperial examination, like the holy way and Wen Bao, can reveal something that ordinary people can't perceive.

Shen Ming continued to read the question comparison. When he reached the third page, he was a little stunned and said, "this question seems to be Zuozhuan." During the period of Duke Luzhuang, I asked about the approximate distance between Qufu, the capital of the state of Lu, and the border of Qi. This question... I'm afraid it's one of the difficult problems in this child test. Fang Xusheng answered a lot, including three paragraphs. It seems that during the period of Duke Luzhuang, the adjacent land of the two countries changed at least three times. I don't know if you can answer? "

Deng Xuezheng shook his head and said, "if you give me enough time, I may be able to answer this question. However, this question is very tricky. Border change is one of them. The most difficult thing is the distance between Qufu and Qi. I'm still thinking after answering the question. So far, I haven't found any books indicating the distance between the two places."

Constable LU Hong nodded and said, "when I see this question, I'm at a loss. I don't know which book records the distance. As for the changes of the border, if there is enough time, I may be able to sort it out slowly, but this question alone may take an hour. Even no one has answered this question this year. Fang Xusheng said that the territory of the two countries has changed three times. Can you solve the puzzle?"

"Please also ask magistrate Fang to solve his doubts!" Shen Ming and Tao dingnian asked for advice together.

Fang Yun glanced at the crowd. LU Hong was a strategist and really wanted to ask for advice, but Shen Ming and others were obviously making fun of him and expected him to say something wrong. After all, knowing the answer and explaining the idea of solving problems in detail are two different things, one is to be able to learn by himself and the other is to teach others.

Without stage fright, Fang Yun said, "if you want to know the territorial changes, you naturally need to know the number of battles between the state of Lu and the state of Qi during the reign of the Duke of Lu Zhuang, which will be determined by the number of battles, location and final negotiations." It is recorded that in the ninth year of Duke Zhuang of Lu, the state of Lu was defeated by the state of Qi. In the tenth year of Duke Zhuang of Lu, the state of Lu defeated the state of Qi with Cao GUI as the general, that is, the famous battle of long spoon, forming a well-known Cao GUI debate, which made it a good story that "one morale, one decline and three exhaustion". You will write this down and mention it again later. In the nineteenth year of Duke Zhuang of Lu, the state of Qi attacked the state of Lu. These are two However, the state of Qi is in the north of the state of Lu. No matter how much territory it loses, it will not cause changes in the distance from the north, so it is not included. In the 13th year of Duke Luzhuang... "

Through Zuo Zhuan, Gong Yang Zhuan, Gu Liang Zhuan and other historical records of the spring and Autumn period, Fang Yun determined that there were three changes in the northern border between the state of Lu and the state of Qi during the period of Duke Zhuang of Lu. These three changes changed the distance between Qufu, the capital of the state of Lu, and the state of Qi.

When Fang Yun finished, Shen Ming and other officials were speechless, and some officials praised him.

"Worthy of being the saint of Fang Xusheng, we are quick in thinking and difficult to reach!"

"In the world, except Fang Xusheng, I'm afraid no one can sort out the wars between the two countries in such a short time. In the spring and Autumn period, wars were frequent, and it was impossible to sort them out without careful sorting."

LU Hong thought for a moment and asked, "Fang Xusheng, you just mentioned the Cao GUI debate and the long spoon war that took place in the ten years of Duke Luzhuang. Why didn't you mention it later?"

"Eh?" the crowd found that Shen Ming immediately became energetic. This may be Fang Yun's omission or a breakthrough.

Fang Yun said with a smile, "Constable Lu, you are still a soldier. Others don't know how to calculate the approximate distance from Qufu to the border of Qi. How can you calculate it? You, die reading, die reading!"

Fang Yun said finally, put away his smile, and the sound made the ears of the people around him buzzing.

Fang Yun, dressed in white, stood in the pavilion, looking serious and not angry.

Everyone present instinctively felt cold everywhere. Even Shen Ming couldn't help lowering his head. Fang Yun was a county magistrate, but he was also a virtual saint!

During the palace examination, Fang Yun could not use the virtual Saint privilege, but everyone could not ignore his status.

If Fang Yun criticizes LU Hong's government affairs as a county magistrate, the officials present can directly refute it. But Fang Yun is now discussing knowledge. Everyone must listen first. After Fang Yun has expressed all his views, everyone can object.

LU Hong looked at Fang Yun and felt that what stood in front of him was not a teenager, but a strict teacher. He didn't dare to be a little angry. He bent down and said modestly, "please give directions from Fang Xusheng."

Fang Yun said, "you recite" Cao GUI's Chen "once!"

LU Hong was still a little confused. After a little thought, he recited in public: "Duke Zhuang of Lu will be a big clock. After the shape is completed, Cao GUI came to see him and said, 'in the past, the house of Zhou was sealed to Lu, 700 East and West, 500 North and South..."

LU Hong continued to recite.

"Cao GUI's Chen", also known as "Cao Mo's Chen", is a book recording Cao GUI, a military strategist of the state of Lu, talking about political affairs and military affairs with Duke Zhuang of Lu. It is a military book. However, due to the long history, even more than 100 years before the birth of Confucius, many books have been lost.

For scholars, the history before the birth of Confucius is relatively vague, which is also the difficulty of this problem.

LU Hong recited the whole "Cao GUI's Chen", but he still had some doubts. The other officials also tried their best to think about it. They didn't know what secret was hidden in it.

When Fang Yun saw that everyone could not think of it, he sighed and said, "LU Hong, I ask you, what is the terrain between Qufu and the border of Qi?"

"It's plain terrain," LU Hong replied.

"How did the state of Lu and the state of Qi fight at that time?"

Without thinking, LU Hong replied, "the chariot is in the front and the soldiers are in the back. There is a single terrain and tactics."

"Let me ask you again. How many days will it take for the state of Lu to resist the Qi army in Cao GUI's Chen?"

"Two or three days at most."

"Can you estimate the speed of chariots and soldiers?"

LU Hong was stunned, and all the officials were also stunned.

Almost in an instant, everyone suddenly realized and showed the color of joy, just like reading something.

LU Hong immediately replied, "I see. In the tenth year of Duke Luzhuang, Qufu was about 110 miles from the border of Qi."

"Good." Fang Yun nodded slightly.

Some officials gathered their joy and looked at each other. They all saw the color of helplessness from each other's eyes.

It's almost impossible for Fang Yun to find out the connection. It's incredible to calculate the distance between the two places through the details of arms scheduling, combat time and chariot speed in the military book. The most important thing is that everything is done in a few seconds.

Deng Xuezheng threw away the test paper in his hand and said, "this question alone, the lower official is far inferior to Fang Xusheng. The lower official recognizes the negative first."

LU Hong also threw away the test paper in his hand and said, "students also admit defeat. The wisdom of genius is far from enough."

The other 11 participants were embarrassed, but they didn't give up, but their momentum was completely crushed by Fang Yun. One by one, they looked like students criticized by the teacher, with sad faces.

Yuan Junwen said firmly, "next question."

Next, Shen Ming continued to answer and check one question after another.
