Li Chunfeng took the schematic diagram of the solar eclipse drawn by Wang Dazhu, looked at it carefully, and couldn't help but be overjoyed.

"Good boy, it's better to be blue! The things that the teacher didn't understand were actually cracked by you. Li Chunfeng excitedly patted Wang Dazhui on the shoulder and praised him.

"Li Aiqing, can you bring me the picture drawn by Wang Xiannan so that I can also take a look?" As soon as Li Shimin saw Li Chunfeng's reaction, he was immediately interested in the schematic diagram of Wang Dazhui.

The emperor wanted to see it, and others naturally didn't dare to refuse his request, so he hurriedly handed the schematic diagram to Guo Ren, and then Guo Ren presented it to Li Shimin.

Li Shimin looked at it, and the process of the formation of the solar eclipse was clearly depicted on the map, which made it clear at a glance, as long as he was not a fool, he could understand the truth.

"Haha...... Wang Xiannan, you really know everything, tell me how you know the cause of the solar eclipse?" Li Shimin's heart disease is gone, and he immediately smiles.

"Back to Your Majesty, the reason why the minister can know the reason for the formation of the solar eclipse is actually very simple, and that is because the minister is good at summarizing and observing the laws of everything in this world." Wang Dazhui straightened his chest and said proudly.

"Oh, just because you're good at observing and summarizing the laws of all things, so you figure out what others don't know?" Li Shimin asked curiously.

"Yes, Your Majesty, everything in this world has this certain law, as long as you discover the rules, many things will no longer be strange."

The other people in the hall couldn't help but ponder after listening to Wang Dazhu's words, some suddenly realized, some were puzzled, and some seemed to understand.

No matter what, Li Shimin finally found an excuse to comfort himself, this solar eclipse is a natural phenomenon and not a bad omen, so it is not that he has done anything wrong, God is unhappy.

"Although Wang Xiannan is young, he is very intelligent, and I think it is worthy of praise for solving my doubts today! What do you think? ”

"Your Majesty is wise, and the ministers seconded it."

……

Speaking of which, there are many stories about solar eclipses in history.

In the history of China, there were special departments and personnel to observe celestial phenomena very early. Its purpose is, first, to understand the operation of the sun and the moon, and to formulate a calendar as precise as possible to meet the needs of agricultural society engaged in farming; The second reason is more complicated, the dominant thought in ancient China is the concept of "the unity of heaven and man", which believes that "heaven" is a god with a will and personality, and the emperor of heaven rules the world, and in the process of domination, the emperor often gives omen and warnings to the world through changes in the stars, so the imperial courts of all generations have a huge celestial organization to monitor the changes of these celestial phenomena day and night.

As the medium and messenger of the human king, the status and prestige of the astronomical officer are extraordinary. Due to the pivotal position of astronomical officials, the imperial court often had high expectations of astronomical officials, and astronomical officials did not dare to slack off at all times.

It is said that at the time of the Xia Dynasty, the fourth king Zhongkang era, the country had just recovered from the turmoil of the Taikang era of the previous dynasty, and there was a bit of "Zhongxing" atmosphere inside and outside the court.

In the golden autumn festival of this year, the wheat waves are rolling, the sky is clear, the farmers are harvesting the fruits of a year's labor in the field, at noon, people suddenly find that the sun that was originally hanging high in the sky, the rays are weakening little by little, as if there is a black monster swallowing the sun little by little - this is "Tengu eats the sun"!

The people were frightened by the sudden and dangerous celestial phenomenon, and hurriedly gathered to bang pots and gongs, so that they could scare the tengu away.

It was the imperial court and the Son of Heaven who feared this celestial sign the most, because the "Tengu eating the sun" was a sign of a catastrophe for the country, which could endanger the emperor's position or life. At that time, the imperial court had already formed a set of "saving the sun" rituals, whenever the "tengu eating the sun" occurred, the astronomical official Xi He who monitored the celestial phenomena should observe it at the first time, and then immediately report to the court as quickly as possible, and then the Son of Heaven immediately led the ministers to set up an altar in front of the palace, burn incense and pray, and contribute coins to the heavens to recall the sun again. But this time, a long time has passed, everyone sees the sun disappearing little by little, and the endless dark night is about to cover the earth. The best time for ambulance had been missed, and Emperor Zhongkang didn't think much about it, and hurriedly presided over the ambulance ceremony.

There was a rush inside and outside the palace, the palace musicians hurriedly beat the drum to save the day, the official in charge of the coins hurried to the treasury to get the money, and the other officials also ran around in a panic to arrange the ceremony, at this time the sky became darker and darker, suddenly, the heavens and the earth suddenly fell into the night, it was difficult to distinguish the figure within a few steps, and the sun was completely swallowed by the tengu. Emperor Zhongkang led the officials to kneel on the ground, begging for forgiveness from heaven over and over again, at this moment, everyone was very frightened in their hearts, thinking that because of the lack of timely rescue, the sun may never come out, and the end of the Great Xia Dynasty has arrived.

I don't know how long later, just when the people felt completely hopeless, a little light appeared on the western edge of the sun, and the earth gradually brightened, and the solar disk was revealed more and more, and the tengu finally spit out the sun! Emperor Zhongkang and the civil and military officials breathed a sigh of relief.

"Tengu eats the sun" finally ended, Emperor Zhongkang only found out at this time that the astronomical official Xihe has not shown up until now, such a big thing happened, Xihe, who was burdened with heavy responsibility, was actually nowhere to be seen, Emperor Zhongkang was very annoyed, and immediately sent someone to find it.

Several servants rushed to Qingtai (the astronomical observatory at that time) and finally found Xihe in the hut where he was keeping vigil next to Qingtai. When he asked Xihe's subordinates, he learned that Xihe had drunk all night yesterday and was still drunk like mud at the moment, and the servants did not dare to delay, so they set up Xihe and stuffed him into the car and sent him to the palace.

When he arrived at the hall and knelt down in front of the Son of Heaven, Xihe was still chaotic and didn't know how much personnel he had. Emperor Zhongkang asked about the situation, only to learn that it was Xihe's drunkenness and mistake, and he was immediately furious and immediately ordered Xihe to be beheaded.

This story is recorded in one of the earliest historical documents in China, this is the first book of the Chinese people, so the name is called "Shu", to the Han Dynasty was called "Shangshu", which means "the book of antiquity", and later because it became an important classic of Confucianism, it was also called "Shujing". Among them, "Yin Zheng Chapter" says:

"Zhong Kang Zhao is in charge of the four seas, Yinhou is in charge of the six divisions, Xi He is abolished, and the wine is short in the city...... It is the new moon in the autumn season, Chen Fu gathers in the room, plays the drums, Sifu Chi, and the people go. Xi and the corpse officials, ignorant of the knowledge, fell into a coma in the sky, and punished the first king. ”
