After Xiang Lu and the two boys in the public loss class gradually moved away, Zhao Wuxian was still looking at the alley in a daze.

"Xiang Lu is just that, except for the name of a prodigy and a Confucius master, he has not left any deeds, all of them are made up by the free brains of later generations, but the public loss class is not the same......"

If it weren't for the same name and the same clan, then this public loss class that behaved a little wooden should be the Luban of later generations. Xiao Gong is also seven years old this year, and he is the son of the craftsman Zheng Gong Lose, and he also belongs to the Chinese class, not a Lu craftsman who has no free body.

However, he seems to be quite interested in these clever things, and the bamboo horses in the hands of the two are made by him, and he also uses wheels and potter's wheels to compare the sun at different times.

In later generations, the public loss class was recognized as the ancestor of hundreds of workers, and he was extremely clever, and the grinding disc was his creation, but now he was robbed of the invention right by Zhao Wuxian. The public loss class brought the skills of craftsmen to the highest peak of the pre-Qin era, many of which were military equipment for siege battles, and only the Mo family could defeat him, I don't know if Mozi would be born.

Therefore, compared to Xiang Lu, whose future is unknown, Zhao Wuxian wants to cultivate the potential stock of Xiao Luban, so that all kinds of clever things he remembered in his previous life may be created by the hands of the public loss class.

Therefore, Zhao Wuxian first sent two clever soldiers to escort them back, and instructed them to write down the addresses of the two, and then monitor and protect them, waiting for follow-up orders.

Now, Zhao Wuxian has to face Confucius's master and apprentice first, and for this side, he has already made up his mind to help the early Confucian "bones", and he has different plans.

……

After meeting on the streets, Zhao Wuxian and Confucius were invited to their home by Liu Xiaji.

Although Liu Xiaji is not a high-ranking and powerful person, he is also a doctor from a public family, and his family's mansion is very large, and he enters three times before and after. The courtyard gate is the top of the hanging mountain, the main ridge is towering, the two sides are slope-like slopes, the eaves extend outward, and the tile of the cloud pattern is paved.

The group got out of the car and walked along the stone road after entering the courtyard gate. It is very wide, stretching out to the middle gate, and when you enter, you will be greeted by a pavilion.

As a famous gentleman in the country of Lu, this pavilion in Liu Xiaji is well maintained.

On the right side of the park is an attic. It is three storeys high, steep and steep, with the four corners of the roof uplifted. On each end of the top ridge is a seabird, which is opposite each other. The building was painted snow white with clam gray, and the doors and windows were painted red.

Downstairs there is a staircase leading into the building. There is a balcony on each floor, and on a good day, you can stand on the top and overlook the scenery by the railing; Whenever it rains or snows, because there is a waist eaves on the balcony, it can shelter from the wind and rain, and the built-in couch seat can also gather three or five friends to drink on the stove.

The sun was just setting west, and it was still early before the meal time, so Liu invited them to sit here next season.

Looking out of the open window, he saw that he was surrounded by bamboo flowers. It's autumn now. The flowers are mostly withered, there are not many bamboos, sparse and sparse, but they are scattered, some of the bamboo leaves are still green, and some have turned yellow.

After retracting his gaze, he saw that the tall Confucius was sitting opposite him, and Yan Huizhi was sitting next to him, both upright, and he really deserved to be "Xi Buzheng does not sit." Confucianism who does not cut and does not eat".

Zilu was arranged by Confucius to drive back to the pavilion first, and at the same time to find the Confucian disciples Zai Yu and others who were still in Qufu.

Confucius saluted Zhao Wuxian respectfully, and once again expressed his gratitude to the Zhongdu for giving grain and solving doubts, and his voice was warm and humble: "Qiu Zengyan." Threesome, there must be my teacher, today is really the case, thank you Dr. Zhao for his teachings, so that Qiu understands one thing again, the doctor has a lot of experience in astronomy! ”

Astronomy originated very early in ancient China. As early as the time of Tang Yao, "it is the order of Xihe, Qin Ruohaotian, the calendar of the sun, moon and stars, and the time of honoring the people", and the position of "Huozheng" was also established to observe the Great Mars to determine the four seasons and solar terms. By the time of the Shang and Zhou dynasties, Tianwen gradually separated from Wuzhu and became the official position of the Son of Heaven and the princes.

The method of observing the sun is naturally among them, and Confucius subconsciously felt that Zhao Wuxian should have studied this aspect.

After listening to Confucius's words, Zhao Wuxian's heart couldn't help but move, and blurted out:

"It's just a fluke.,No shirt is just such a little strength.,I like to think deeply when I see something I don't understand.。 The ancestors of the Zhao family admired the sun, and the head of the family was compared to the sun many times, so I had some thoughts and understandings after observing it when I was a child. ”

This explanation is reasonable, the family surnamed Ying started from Shaohao, and they originally liked to look up and chase the sun, and the Zhao family also embroidered her on the flag, and it is common for a descendant to watch the sun and enlighten the Tao, and everyone believes it.

Wuxian's voice changed: "However, what I just said is only a superficial opinion, and there is no way to prove whether it is right or wrong, if someone can measure the distance between the sun and the earth, then this mystery can be completely solved." ”

"Sun-Earth distance!?"

Not only Confucius and Yan Hui were stunned, but even Liu Xiaji, who was sitting on the top, was also shocked.

How can the sun, which seems to be the eye of the Emperor of Heaven and the divine object above all things, be measured by man?

Confucius said: "Yi clouds, the law is as big as heaven and earth, the flexibility is as big as the four hours, and the hanging phase is as famous as the sun and the moon." When Qiu was young, he studied astronomy and geography with Zhou Doctor Chang Hong, and he was also curious about how far away the sun was and how high the sky was, but he never thought to really measure their distance. ”

As a believer in the "Heavenly Way and Humanity" and a deist who "worships ghosts and gods and stays away", Confucius was in awe of the sun, but he did not regard it as a sacred and unpredictable thing, which can be regarded as a relatively progressive doctrine of this era.

Yan Yuan, who was extremely curious, asked with blazing eyes: "Zigong once said that when the doctor was in the Jin Kingdom, he had a plan of officials and famous overseas Chinese, who mastered the magical Zhou Ji numbers and used unusual arithmetic laws to calculate. Could it be that he has already reached the realm of the heavens and the earth that can ascend without steps, and the earth cannot be measured by the size of the heavens and the latitude and the earth? ”

Zhao Wuxian's gaze turned to Yan Hui, he knew that this young man in his twenties, with straight eyebrows and wide eyes and a simple and amiable expression, was the only disciple of Confucius, and was praised by Confucius as "sensitive to things and cautious in words".

Zhao Wuxian thought that Zigong, who was already extremely smart, also reluctantly called it "Hui also heard one to know ten, and gave one to know two", that is to say, Zigong learned one and knew two when he studied, and Yan Hui was terrifying to hear one and know ten, and even Confucius said to Zigong: "Fu Ruye, I and Ru Fu Ru Ye", admitting that even he is not as good as Yan Hui.

In short, this is a scholarly figure, and now he is the most promising successor to Confucius, and it is said that he has dabbled in both astronomy and geography, and is characterized by studious and intelligent, and likes to put anything in his head. But because he is low-key, he is not conspicuous, and he does not intend to be a politician, and he devotes himself to serving Confucius and researching knowledge.

Yan Hui's eyes were filled with curiosity, he had already been attracted by Zhao Wuxian's words.

Wuxian replied: "Not yet, but I believe that if someone can continue to carry forward this path, sooner or later it will be realized!" ”

In the face of Zhao Wuxian's proposal to measure the distance between the sun and the earth, Yan Hui showed great interest, but Confucius had other ideas.

He smiled and said: "When the first monarch was Zhao Gong, Qiu was once given a car, two horses, and a shaft to serve by the first monarch, and entered the Zhou room to greet the gift accompanied by the Meng family's concubine. I met Lao Tzu in the Zhou room, asked him for advice, and when I was about to leave, Lao Tzu said to me......"

"Wisdom and insight into everything will lead to death, and being well-informed and broad will endanger one's body. Dr. Zitai wants to know the world and see everything, what do you think of Lao Tzu's words? ”

This is not Confucius's own opinion, but a paraphrase of Lao Tzu's view.

Zhao Wuxian shook his head and said: "Lao Tzu is a fussa, he is the same as the sons of the Lonely Bamboo Kingdom, Boyi, Shuqi, and Confucius's disciple Zihui, he is a ruthless person, advocating great concealment and great foolishness. ”

"However, Dr. Zitai can be said to know Lao Tzu and his people, birds, I know that they can fly; Fish, I know they can swim; Beast, I know it can go. Those who can run can be caught with nets, those who can swim can be fished with silk lines, and those who can fly can be shot with arrows. As for the dragon, I can't know its whereabouts and trajectory in the sky, I can't figure it out, Lao Tzu's knowledge and personality are like a dragon that enters the clouds. ”

In this case, Confucius thought that there could be a few dragons in this world? Lao Tzu's deeds and practices are not something that ordinary people can emulate. Most people still need birds, fish, and beasts that worry about food, clothing, housing, and transportation, so Lao Tzu's statement is not fully recognized. The things in this world are like today's two children's debates, the more they argue, the clearer they become, not the foolish ones who don't understand can escape. I think that after a hundred years and a thousand years, not only the distance between the sun and the earth can be measured, but the sky is big, the earth is wide, the sea is deep, the source of the river, why the sun rises in the east and sets in the west, and why people are born, old, sick and die, one day we will be able to know one by one. All of these are what I call ......"

"The Way of Learning!"

"Knowledge?" Everyone was stunned, waiting for Zhao Wuxian to explain this meaning-sounding word.

On the balcony in the attic, Zhao Wuxian said to Kong Qiu, Yan Hui, and Liu Xiaji:

"As the primate of all things, we should naturally know the essence of all things, so that we can use them for the benefit of all people. Let's make an analogy with Wuxi, in ancient times, the Suiren clan looked up at the stars, and looked down at the five trees to create fire, which is the knowledge of Gewu. ”

After that, as the king of the world, Bao Xi looked up at the sky and looked down at the law. He watched the markings of birds and beasts and the water potential of the mountains, or took the law from himself, or comprehended all things, so he began to create gossip, which was used to comprehend the morality of heaven and earth, and to express the situation of all things, which is also the knowledge of things! ”

"Hundreds of years after the death of Bao Xi, the Shennong clan rose, he tasted all the herbs, observed the growth characteristics of all things, so chopping wood for plows, kneading wood for plows, and creating many utensils, in order to teach the people to cultivate and weed, so that the world can increase food, this is still Gewu Zhizhi."

Zhao Wuxian's remarks were progressive and logical, and they also catered to the habits of Confucius and his disciples who were good at the ancient sage kings, and were extremely persuasive.

So he finally said categorically: "Therefore, in addition to understanding the truth of the growth, prosperity and decline of all things, Gewu Zhizhi can also know the source of etiquette and pleasure and the key to morality!" ”

"Wonderful! Today, we know the wonder of knowing things! After a moment of silence, Confucius first made a sound of approval. (To be continued.) )
