For a long time in ancient times, lunar eclipses (lunar eclipses) were mostly considered to be "tengu eclipse of the moon".

Even if there were special celestial officials later (Qin, Han and Southern Dynasties, Taichang belonged to Taishi Lingzhang Tianshi ephemeris, the Five Dynasties and the early Song Dynasty were called Si Tianjian, and the Ming Dynasty was changed to Qin Tianjian) to observe the waxing and waning of the sun and the moon from the perspective of celestial phenomena, most of them linked the solar and lunar eclipse with the affairs of the world under the thinking of "the unity of heaven and man", and regarded it as a manifestation of "catastrophe".

If you are familiar with the ancient history of the Three Kingdoms and other ancient history, you will find out. But whenever there is an earthquake, a meteorite, a solar eclipse, a lunar eclipse, or even a great water plague, it will be considered that the Son of Heaven is immoral, and the third prince will write a letter to ask for his resignation (Emperor Ling: Hehe, it can be sold again). Carry this black cauldron for the emperor. Of course, from the scientific view of nature, the emperor actually inexplicably turned his back on the black mouth.

In fact, there were two different currents of thought about the understanding of lunar eclipses in ancient times.

In addition to the Han court, which believed in the way of Lao Zhuang, paid attention to the rule of inaction, and the induction of heaven and man, there were also a group of super cattle people who could be called the ancestors of science in later generations, with different views.

In terms of timeline, the earliest correct explanation for the solar and lunar eclipses was Liu Xiang, a scholar in the Western Han Dynasty. In about 20 B.C., he said: "The sun eclipse, the moon obscures it." ”

Translated, it means: "The so-called solar eclipse is when the moon passes and blocks the sun." Liu Xiang didn't say how to block it. By the time of the Eastern Han Dynasty. Zhang Heng, who invented the armillary heaven and earth motion instrument, gave an explanation in "Lingxian": "The moonlight shines on the sun, and the spirit is born in the shade of the sun; The day is bright, and the day is gone...... In the rush of the day, those who are often out of harmony with the light are hidden from the ground, which is called darkness. In the stars, the stars are micro. When the moon meets, it is eclipsed. ”

In other words, Zhang Heng has realized that the moon itself does not emit light (note that) the light is given by the sun, and has also pointed out the principle of the appearance of solar and lunar eclipses.

By the Song Dynasty, technology had reached the pinnacle of Chinese history. At that time, Shen Kuo, a scholar at that time, mentioned three records directly related to the sun, moon and celestial phenomena in his encyclopedia "Dream Creek Writings". One of them said that an unmotivated junior asked Shen Kuo: "The sun and the moon are shaped like pills, how do you know it?" ”

Senior Shen Kuo smiled slightly: "It can be verified by monthly profits and losses." The moon has no light. Judah silver pill, the sun is the light ear. The light is born, and the sun is beside it, so what is seen on the side of the light is like a hook; As the day gets farther away, it shines obliquely, and the light is slightly fuller. If it is a projectile, coat it half with powder and look at it sideways. then the powder is like a hook; If you look at it, it will be round. This has to know that it is like a pill. ”

Translated into the vernacular, it says: "It can be verified by the profit and loss of the moon phases." The moon itself does not shine, like a silver ball. It is the light of the sun that gives it light (the heirs of science). When the moonlight is first generated, the sun is next to it, so that only one side shines and the moon is like a hook; As the sun moves away and begins to shine obliquely, the luminous part gradually increases. It's like a projectile. Coat its half with powder, and when you look at it from the side, the powder is like a hook, and when you look at it, it is a circle. That's why we know that the sun and moon are shaped like balls. ”

That's a lot of imagination.

It's just that. Senior, you can't also travel through the past......

However, in the Qin realm, the lunar eclipse is indeed a very serious celestial phenomenon.

Why is it a lunar eclipse, not a solar eclipse, Murong Kai is not very clear. Wu Chen obviously thought more: "If the dead candle dragon on the other side of the Flame Mountain is the guardian of the entire world. Could the lunar eclipse have anything to do with him? ”

"Master, I don't know about these secret things." Murong Wei said: "The mission of our ancient relics is to protect this world. So, a long, long time ago, when humans had not yet become the spirits of all things, we stood guard around the Nine Shadow Rifts. Fight the demons that have risen up. As humanity became the new masters of the world, this mission was entrusted to them. Nowadays, among the palace merchants' horns, there are only 'signs' and 'feathers', which are guarded by the demon clan, and the rest are humans. ”

"I see." Knowing this, although Wu Chen's entire world view cannot be said to be complete, it has also made up for a large piece that is missing.

He had known a long time ago that the Heavenly Demon Qin had a demonic nature. However, when I came to the middle of the piano, it was peaceful and happy, and it was simply a paradise in the world. Don't talk about demons, even demons are very charming.

A huge, fortified city. When Wu Chen entered the city, he sighed, why did a town build such a tall city wall. Now it seems that this Songwu Town is not a prison city? It's just that all kinds of people who live in it are all trying to resist the demons under the Nine Shadows!

Therefore, the real meaning of calling a giant city 'town' should be: 'Songwu Town Shoufu'!

Simply called Songwu Town!

And each city is independent and has few contacts. Thinking about it now, it doesn't make sense. In case a certain town guard mansion is broken by demons, the city gate is closed tightly, and the walls are cleared, the loss can indeed be minimized!

If you go deeper, why only hunters can come and go freely, is it suddenly clear (tsk!) Take a look at the details of the author's fungus ghost crying and howling, and think about it carefully! ）？

In the era of national resistance to demons, prisoners were also given a more important meaning. Just like the death squads formed by prisoners in wartime, the felons who were imprisoned in the shackles of the heavenly prison bore the brunt of the first wave of cannon fodder to resist the invasion of demons.

Then there was the entire town guard mansion, as well as the horn lord Han Baili, followed by all the masters who lived in the city. If the whole city falls......

Wu Chen sighed.

The seemingly beautiful world has cruel secrets behind it that no one knows. The piano world is no exception.

Because the goddess's toenails are still worn on the face of the ghost car, the demon refining furnace cannot be refined. This is the same as the fact that the system files that are in use cannot be deleted. Of course, it is impossible for them to come up with it. For a while, there can only be a stalemate. It was important to save people, and Wu Chen, who couldn't find a way, immediately rushed to Songwu City by the machine transformed into Murong Wei's divine soldier. Beigong Yu had been sleeping in the cave mansion, and Wu Chen didn't plan to wake her up.

Just as there are gates on the ground. Cities floating in the clouds also have gates built on two white clouds.

The city gate is like a covered bridge, flying above two clouds that resemble somersault clouds. Driving closer, Wu Chen vaguely discovered that there was also a pedestal hidden in the clouds that was obviously a trap. The wind is the essence of water, and these clouds are actually condensed by the water vapor around the base.

And this covered bridge flying above the clouds also has an exclusive name: Que Gate. It means a high platform built in front of a palace, ancestral temple or mausoleum. Usually one on the left and one on the left, and the stage is upstairs. There is a road between the two. The same is true of the gate in front of me, except that this invisible and untouchable road is called a fairway.

Cities in the air, like cities on the ground, are guarded by guardian circles. It seems that they are dotted all over the place, and they are not related to each other, but in fact, the five elements are born and closely related. It is built year by year by the masters of the exquisite woodware workshop used by the queen of the horn lord for generations. The circle is extremely powerful. Except for a separate entrance. The rest of the location is impregnable.

Wu Chen also knew that every town guard mansion in the Qinzhong Realm was a trinity. Air, ground, underground. The sky is the city's most central asset. For example, Zhuge is quiet and exquisite, Gongsun Ban's Tiantian Pavilion, and this time Wu Chen is going to the Tianyi Temple.

As mentioned earlier, the naming of ancient buildings is extremely particular. Accumulate soil 'Quartet High Abbot Said Terrace'. Those who do not have a side are called 'view' or 'que'. So, this one floats in the clouds. The circular three-story building similar to the Temple of Heaven is the Tianyi Temple.

The Tianyi Temple is not a Taoist temple.

As the name suggests, this is a garment shop. It's just that the shape of the building is a circular 'view'.

The needlework shop on the ground sewed some ordinary clothes and skirts. Tianyiguan sewn high-grade armor. For example, the robe of a warlock, the leather armor of a warrior, the hunting suit of a hunter, and so on. The biggest difference from the blacksmith is that all the materials are mostly lightweight monster fur. Supplemented with monster skin scales and a small amount of high-grade metal. The armor forged by the blacksmith shop is medium and heavy armor with a high proportion of metal.

The trading of Tianyi Guan and Mending Heaven Pavilion has different emphases, but there are overlapping parts, so there are often contacts. Complementarity.

The guards on the ground all knew Wu Chen. Word must have spread about the massacre that took place at the Great Snow Plains Hunting House. To be on the safe side, Wu Chen did not walk on the ground. As he thought, the warriors guarding the Sky Gate did not know him.

The machine ship under the banner of a hunter was allowed to enter and exit the city after paying a sufficient amount of gold and silver for the entry and exit code told by Madame Rose.

Wu Chen subconsciously breathed a sigh of relief.

The machine stopped all the way and moored all the way to the stone steps in front of Tianyi Temple.

In any case, walking up the stone steps along the deck down the suspension bridge is like going down from a passenger ship to the pier. It's just that compared to the stairs that stretch into the water at the cruise ship terminal, the stairs of Tianyiguan stretch into the sea of clouds.

The hunter's machine ship is docked at Tianyiguan, which is completely reasonable. After all, the fur and scales of the sewn haute couture came from the hands of hunters on the snowy fields. It is also a very common thing for machine ships to take off and land.

Waiting for Wu Chen to carry a stack of gorgeous furs and stride into the Tianyi Temple, the garrison ship cruising back and forth in the sea of clouds, and left with interest.

There's nothing wrong with this hunter's trap ship.

Entering the Tianyi Temple, under the leadership of the ladies, through the dazzling semi-finished shelves and quiet embroidery rooms, circled up, and arrived at the secret room on the third floor.

Madame Rose was already waiting there.

Mrs. Rose from Hong Kong is dressed in a Luo skirt with cloud sideburns, dressed as an ancient lady. It is estimated that he is an A-level plot character, with a beautification bonus, and he is far more glamorous than what Wu Chen saw in front of the screen. It is not an exaggeration to describe it as beautiful and charming.

Compared to the divination of the ghost car, Lady Rose's is more inclined to psychics. The results of her divination were not seen with her own eyes, but were told to her by the goddess of ice and snow, and she said it through her mouth.

"As you know, Luo Lie was escorted into the shackles of the Heavenly Prison. Although he was not executed, his life was not long in coming. "Madame Rose gets straight to the point.

"How can I get into that prison?" Wu Chen asked.

"Getting into prison isn't a problem." Madame Rose apparently knew more from the goddess than Bighorn: "The point is, it's a trap. ”

Wu Chen understood: "Please enter the urn?" ”

"That's right. Han Baili's purpose in imprisoning Luo Lie is to lure you out. Because, whether it is to save people or extinguish the mouth, we must explore the prison. Madame Rose bowed slightly. (To be continued.) )
