Modern research has drawn a conclusion that due to the influence of astronomical precession, the stars in the sky will retreat 360° on the celestial sphere every 26,000 years, one solar term every 1083 years, and one season every 6500 years.
Although the ancients did not have as advanced astronomy as modern times, they discovered the existence of precession through observation and recording.
Yu Xi of the Eastern Jin Dynasty said: "In Yao's time, the short star Pleiades on the winter solstice was in the east wall 2,700 years ago, so we know the difference in the distance every year."
"Shuowen Jiezi" also says: "Dragon is as long as a scale insect. It can be dark and bright, thin or giant, short or long. It ascends to the sky at the spring equinox and dives into the abyss at the autumnal equinox."
In modern times, if you want to see the scene of "Canglong Qisu" hanging in the center of the southern sky after dusk, you have to wait at least until the Great Summer Festival. The ancients said that it hung in the center of the southern sky after dusk on the vernal equinox, which refers to the astrology of at least 12,000 years ago. p>
In the era of Emperor Yao 4,500 years ago, the Zhuniao constellation, the Qinglongfang constellation Fire, the Xuanwu Xu constellation, and the White Tiger Pleiades constellation.
"Yao Dian" records the celestial phenomena in spring, summer, autumn and winter, which shows that our ancestors have developed extremely excellent astronomical observation capabilities as early as ancient times, and China's civilization is glorious and splendid.
But today, after reading this article, Jia Lan has some other associations.
After the great chaos, there must be great rule. Emperor Yao created a generation of sage kings and ushered in a prosperous age.
So, what about the history before Emperor Yao?
What was the chaotic era before the Great Reign?
There is no record of this in "Shangshu".
Perhaps, "Shangshu" originally had relevant records, but they were lost.
Or maybe the records in "Shang Shu"... are false?
The discussion on the authenticity of various versions of "Shangshu" does not originate from modern times. In fact, Zhu Zi had already raised doubts as early as the Southern Song Dynasty:
""Shu" has ancient texts and modern texts. The modern texts are oral transmissions from Fusheng, and the ancient texts are books on the wall... All Yi readers are ancient texts, and what's more, they are academic books... How can things that have been in the wall for hundreds of years be safe?
A single word of corruption? But Fu Sheng remembered that it is difficult to read, which is particularly suspicious. Today's interpretation of the whole book must not be true."
Although there are doubts and falsifications, it cannot be denied that there are still many exquisite texts in the ancient text "Shang Shu", and it is still a treasure of Chinese culture.
Just like the sentence "The human heart is dangerous, the Taoist heart is small, the essence is only one, and it is allowed to hold on to the center", it comes from "Yu Mo" which has been proven to be a forgery, but it does not prevent Zhu Xi from extending and developing this sixteen-character mantra into an influential one.
The great Neo-Confucianism of later generations got rid of the traditional exegesis-based model since the Han and Tang Dynasties, and instead took the doctrine as the core of interpretation, and set the goal of exploring the minds of the two emperors and three kings as the goal of interpreting the Bible.
But what Jia Lan cares about at this time is not the authenticity of "Shang Shu", nor the diction in it, but the history in it.
Compared with literature, history is history, black is black, and white is white.
Maybe different people have different interpretations, but history is history and it does exist.
After experiencing time travel and seeing Lihentian, it is difficult for Jia Lan not to think about things in a mysterious direction.
The existence of Yu Linglong has confirmed the existence of the ancient gods, but Jia Lan discovered that in China, which has vast ancient books, there are very few records about ancient times. Even the "Biography of Immortals" was written in the Han Dynasty.
What causes the loss of ancient history?
Boom, boom...
Jia Lan subconsciously tapped the desk with his fingers, going through a brainstorm in his mind.
"What was the history before Yao? Why does Shangshu begin with Emperor Yao? What about the records of Huangdi?"
"I should know."
Jia Lan suddenly raised his head, and the figure of the younger brother appeared in front of the desk.
"Brother, do you know?"
The little brother's expression was noncommittal, his eyes were a little dazed, and he was obviously deep in thought.
The candlelight in the room illuminated my handsome face.
He is a uniquely handsome man. His appearance is very three-dimensional, his limbs are long and strong, his eyes are dark and far-reaching, but his face is the same as the patient's, showing a kind of empty paleness, which embodies a masculine and feminine character in him.
Combine.
"Well..."
After a while, the little brother suddenly groaned.
"I can't remember."
Jia Lan was startled and said hurriedly: "Forget it if you can't remember it. Don't think about it anymore."
The little brother responded with a hum, took a few deep breaths, and gradually relaxed his frown.
Seeing this, Jia Lan also breathed a sigh of relief.
"Sorry." The little brother said, "I'm sure I know it, but whenever I think about it, my head can't help but feel severe pain."
The little brother is a person who has lost his memory. He has been wandering just to find his lost memory and life experience.
If he hadn't told Jia Lan clearly that he had not robbed a tomb in order to find his memory, Jia Lan would have doubted whether he had been involved in a conspiracy.
"At present, our goal is to first pass the imperial examination and enter Shenzhang Pavilion to check the information, find the clues about the 'book cliff' you mentioned, and then uncover the mystery step by step..."
The little brother had returned to his usual silence at this time, just nodded and said nothing more.
"By the way." Jia Lan suddenly remembered something, "Have you found any clues about Master Miaoyu Fairy's magical weapon?"
Miaoyu had previously asked Jialan to help retrieve the magic weapon that her master Huijing had lost in Muni Yuan. Jialan was worried that this matter would involve some mysterious incident, so he did not ask Ni Er, and only asked his younger brother
In my spare time, I go out to inquire.
I originally thought that the fire in the Muni Temple happened a few years ago and there would be no traces left. Unexpectedly, the little brother actually said: "I found a few clues."
"What?" Jia Lan was slightly surprised, "Then what?"
"The clue is broken."
"..."
After a moment of silence, the little brother added: "What can be confirmed is that the fire at that time was indeed man-made. The other party did it cleanly and did not leave too many traces. The clues are broken..."
"There is nothing we can do if the clues are lost. After all, it happened several years ago, so we can only look for it slowly."
After a while, Jia Lan suddenly felt something was wrong.
"You will tell Fairy Miaoyu what you have discovered and she will have no clue?"
The clues to Muniyuan’s reality are broken, so is Miaoyu’s magical sixth sense?
"No." The little brother shook his head. After a pause, he couldn't help but said: "She has been struggling for a long time, but it still doesn't work."
"Trouble?" Jia Lan was immediately confused, and it took him a long time to figure it out.
Miaoyu's heart hexagram moves according to her heart, and she pays great attention to opportunities.
In order to find inspiration, Miaoyu sometimes does strange things, such as counting flower petals, or talking to herself.
Jia Lan couldn't help but find it funny, thinking that Miaoyu also worked hard for her master.
"Master!"
Qingwen's pretty voice came from outside.
The little brother dodged and disappeared from Jia Lan's eyes, and then Qingwen walked in holding an oil lamp.
"My wife asked me to deliver a message. It's time for dinner."
"Okay, let's go." Jia Lan put down the book, stretched, then stood up and followed Qingwen out.
This feeling of studying in your own home is really good.
