Yu Zai conducted astronomical observations on this high mountain that only existed in the mythical world. This was the best place Yu Zai had ever found and seen, allowing him to better explore the mysteries of the world.
Yu Zai can determine many things, such as the trajectories of the stars and the sun and the moon. Their movement results are the same as the data predicted by themselves. However, the original observation data still cannot determine whether it is the correct large universe or the four directions of the cloudy sky. In the world, Ruanzai's understanding of the field of astronomy is limited to what he has learned. After all, geography and astronomy are two different fields. There is overlap and learning, but it will not go too far.
However, no matter how magical this unexpanded world is, to observe the movement of the sun, we must use the celestial sphere model. The so-called celestial sphere refers to a sphere with the observer as the center and infinite length as the radius outward. On the celestial sphere, we can see the projection of any celestial body, including the projection of the sun.
Then, what the observer sees on the earth is the movement of the sun on the celestial sphere, which is the apparent movement of the sun. On the solar apparent movement map, we can determine the sunrise and sunset directions of a place, the length of day and night, and the direction of the sun in the sky at noon.
Hongchao couldn't understand what Yuzai was doing. He was confused and felt that studying was really hateful.
It's because of top academics like you that the world of underachievers is so broken, you bastards!
And Chi Songzi was also very angry!
My dear disciple, I brought you here to level up, not to let you build the wonders of an observatory!
But the dissatisfaction in his heart turned out to be dissatisfaction. He said that he would build a simple observatory and said that this was also a kind of natural principle and could be extended to more natural principles!
As soon as Chisongzi heard this, she immediately ran to help.
Good disciple, if you want Master to do anything, just ask!
"I once gave Shuhai a stone ball because I had observed that the earth was round."
"This sounds ridiculous..."
Hong Chao was not interested in this and thought that Yu Zai was talking nonsense. If Dadi was a ball, wouldn't he be singing and dancing rap anytime and anywhere?
Hello everyone, I am practicing the Earth’s two-and-a-half-year revolution?
But Ruanzai took a new stone ball and made a simple parallel view, making the shapes of revolution and autobiography. Hongchao, no matter how poor a student, understood it.
He suddenly began to doubt the whole world.
"If it's a ball, why won't I fall out?"
"Because there is a great force that holds you to the ground."
Ruanzai wrapped a rope around the stone ball, and then started to spin in circles. This new explanation made many problems in the past suddenly come to light. Chisongzi suddenly realized it, but Hongchao fell into fear!
"It turns out there was someone I couldn't see dragging me away!"
Hongchao was shocked:
"No wonder I always roll out of the straw mat when I sleep. It turns out that this force is also at work!"
In the early morning of the next day, everyone watched the sea of clouds rolling in the east. The outline of the sun appeared, very distant but also very huge. It appeared from Tanggu, moved from the mountains where the sun and moon emerged, and arrived at Qu'a Mountain. At this time, The data recording has already started.
Hongchao helped Ruanzai get a lot of key materials, and he searched for them in the mountains because Ruanzai wanted to make an ancient astronomical telescope.
The sun came over, getting closer and closer. Under the brilliance of the evening, it was extremely huge and began to approach Kuangji Mountain!
Boom!
It was like something was making a huge, hollow, echoing sound, and the waves in the sea of clouds were like angry waves. Yuanzai felt that the sun totem was erupting with power!
Calling!
Ancient totems are the source of strength and spiritual sustenance for humans and gods in the past. They reflect the true nature and principles of all things in the world. In the world of gods and ghosts, and in the world of materialism, illusion and reality are intertwined!
Yuzai felt the wind!
It was the vast wind brought by the ancient distance. Now that he was in this wind, the sun's totem pattern all over his body was dazzling, like a real flame.
At this time, Yuzai asked Chisongzi and Hongchao to help him record the data, and then he was ready to start congratulating!
The sun stopped.
It was short, but it did stop!
No, it is the light of the sun that remains.
This mountain is a mythical mountain. It has a long sunshine time and cannot be inferred by common sense. She had some ideas in her mind, but she needed further confirmation. She suddenly became very happy because this mountain is magical. Mountain, it contains countless treasures.
As a master of geography, it is natural that we should establish an observation station here.
When Yu Zai entered Zhu's world, what came face to face was still the ancient and distant illusory land, but due to the influence of the two suns, the desolate world was no longer desolate!
Yan Zai began to simulate the changes of the sun throughout the day. The last time he became a great witch-level Qi practitioner, Yan Zai had already simulated it. After Heng Yang died, the sun rose and everything revived.
From death to life.
In Zhu's world, with the call of the sun approaching the sky and the earth, Heng Yang and Chaoyang, the two suns actually began to overlap and merge!
Afraid of the order of heaven and earth, I will march westward with a bright spirit!
Yu Zai felt the change. The two suns merged into the sun totem and changed into one. Then the day began to cycle over and over again, and the years began to migrate. Although this great power was still at the level of feeling and philosophy, Yu Zai could already Touched to a point.
The name of this kind of sun is "Yao Ling"!
Different names represent different powers and meanings. Just like the red pine tree talked about the types of rain, the Yellow Emperor also called out the names of various thunders in the south.
And at this moment, another "sun" appeared!
When Yuan Zai saw the circle, he was a little surprised, because the sun totem was merging with Taiyuan at this time, so Yuan Zai woke up, looked at the outline of the sun that was about to leave, frowned, and wanted to give it a try. , and drew Taiyuan against the sky!
It is a circle, the same circle as the sun!
The outline of the sun overlaps with Taiyuan!
In Taiyuan, both Hengyang and Chaoyang returned to their original state, so in an instant, the Taiyuan phase in Yuzai's hand suddenly dispersed, leaving an afterglow of flames and disappeared instantly.
Yuzai was stunned for a moment, looked at his hands, and then touched his head.
Is something wrong?
It seems that some experiments are still needed...but fortunately, there is indeed a reaction, which is a good start.
.......
Yan Zai conducted observations for a period of time, and after recording enough astronomical data, he began to practice again. On the contrary, Chi Songzi became obsessed with the act of conducting astronomical observations.
Because Yu Zai made a "Galilean telescope"!
[Congratulations on unlocking the technology "Astronomy"! 】
[Build a university near a mountain, allowing you to build an observatory! 】
This kind of ancient telescope is easy to make, because Yuan Zai has already pointed out the optical technology, Chonghua has been equipped with glasses, and it was made by Yuan Zai and Xiong Tao together.
Only a convex lens with a larger diameter and focal length is needed as the objective lens, and a concave lens with a smaller focal length and diameter is used as the eyepiece.
Use swim bladder glue and small grooves to assemble the two lenses, stick them in a hardwood tube, and then make a simple pedestal. Then a telescope that can see the mountains on the moon, the stars in the Milky Way, and the satellites of Jupiter is ready. Made!
For the sake of beauty, Yu Zai made a copper tube and carved patterns of the sun, moon and stars on it. Chisongzi was completely fascinated by this "artifact". He got the ancient astronomical telescope and immediately began to search for the location of the Taiyi star.
