"The distinction between these three theories lies in the difference in observation benchmarks.

But fundamentally speaking, Xuan Ye said that it restored the essence of the sky.

If we do not set any observation benchmark, the sky will be like eternal night.

There is vital energy in the eternal night, and vital energy stops to become stars.

The sun, moon, stars and stars are formed by the vitality, and they are suspended and shining in the eternal night, so it is called Xuan Ye.

The Kunqin we set up is also one of the vast stars.

Xuan Ye's theory is the ultimate theory used to understand the laws of movement of the heavenly vital energy.

And if we use Kunyu as the benchmark to observe the eternal night in the sky, then Kunyu will be like an egg hanging in the air, surrounded by vital energy.

The vast night is like a curtain, and the stars project on it, which is the sky.

Huntian is a theory that depends on the observation of the changes of stars with Kunyu as the center.

The so-called mosaic is a tool for observing the sky based on this theory.

The small ball in the center of Hunxiang represents Kunyu, and the longitude and latitude form the Huntian.

But if we pull the observation target back to the public, we can measure it visually within our field of vision.

At this time, the sky is infinitely large and the earth is infinitely large.

The earth line is close to the level, and the moment is square, and the earth is seen with a square meter. This is the saying that the sky is the saying.

This theory is not only easier for us to accept and understand, but also is our direct perception, so this theory is the most widely spread."

As he spoke, he looked at the expressions of everyone.

Qingyun and others naturally felt confused and looked confused.

Even the prodigy Zuying was thinking, frowned, as if she didn't understand everything.

But Xin Dufang's eyes shone brightly when he heard it, as if every word and sentence hit the sky spirit, opening a mind.

The more he listened, the more excited he became. When the words were finished, he stood up and applauded.

The little prince was calm, with no strange look in his eyes, and he could not tell whether he was praising or dissatisfied with the words of Xun Dufang. He just saw Xin Dufang agreeing and asked,

"Do you have something to gain?"

Xin Dufang nodded like pounding garlic.

"Little Prince, Du Fang seems to understand a little.

The prince wants a prototype that can be created at the end of the year."

"What?"

The eyes were so shocked that their eyes almost broke out of the frame.

This kid wants to create a self-image through such a general description?

But then he thought about it again. This guy had already obtained the essence of the description of the sky with the sky. He was not a piece of blank paper for astronomical measurements. It should be said that he was already an expert in the world.

What he lacked at this time was probably just a pioneer instructor to answer questions and solve problems?

So I felt relieved, and I gathered my mind and bowed my hands.

"Actually, if the little prince is interested in this, I can take advantage of the past few days to disturb me and draw a simple picture of the mosaic.

However, in exchange, I hope the little prince can do me a favor."

"oh?"

When the little prince heard that he could draw a picture of the elephant, he was very happy.

"What does Mr. Jing Shuo need? Even if I say that, I will do my best."

"I need to find some colorless gypsum crystals, as long as the pigeon eggs are used together for urine and defecation."

The little prince couldn't help but become curious and informed about its purpose.

I didn't hide it, so I briefly introduced the device I wanted to make for long-distance aiming, but it still lacks some hard materials that are highly transparent, easy to shape or polish.

"Oh, there is no colorless gypsum crystal in the lonely mansion.

But if I only need some transparent materials with moderate hardness and suitable for polishing, I have some, and I don’t know if it is suitable for use.”

The little prince called the servant and gave a few instructions. After a while, someone held a brocade box.

The little prince opened the brocade box and took out a few transparent cups of unknown texture from it.

The cups were exquisitely crafted and swayed under the candlelight. Although they were covered with a hint of verdantness, their transparency was extremely high, not much less than crystal.

Shi Zhi took one of them, took a dagger and gently scratched it on the edge.

The hardness feels like it is just right, not easy to deform, but also understandable. If it can be heated and shaped, it would be even more perfect.

He couldn't help but say happily, "Little Prince, what kind of strange thing is this? It looks like the texture of glass and the brightness of crystal, which is unprecedented."

"Oh, this is the Pole luminous cup, produced in the Western Pole Kingdom.

The Western Regions used this cup to appreciate the wine of grapes, but it was not a treasure. The same material was very rare in the Central Plains."

"Poli Kingdom? I am ignorant."

"There is a ministry in the Western Regions called Gaoche.

Gaoche's home country is outside the Pamir Mountains, west of the West Sea, and on the banks of Gaojiasuo Mountains.

In addition to Gao Jiarui, there is also Qifu Kingdom, which was born from the Western Qin royal family.

To the west of Qifu, there was a country called Poli, which was thirty thousand miles away. It was north of Tiaozhi and east of Daqin. It was always close to Qifu Gaoche.

This set of cups is a tribute from the Gaoche people."

Talk about it and everyone gets the needs. This banquet is a joy.

When everyone was in a daze, it was late at night.

The manager took the four people back to his residence, and Qingyun was silent all the way.

Xu Zhi saw it and said with concern when the manager left,

"Does the fifth brother have something to worry about?"

Qingyun sighed softly,

"In recent days, I have seen several kings of Wei.

The eldest brother is righteous and will not talk about it anymore.

The King of Anfeng in front of him was also wise and decisive. It is said that there were at least two young masters in the Yuan clan who were not under him.

Even King Yuanyu of Guangling and Prince Yuan Xun whom he met yesterday, although they are not dragons and phoenixes, they can be called good horses, and they each have their own pride."

Xu Zhi looked at Qingyun quietly without interrupting, as if he already knew what Qingyun was thinking.

But he didn't want to say it out loud, because what Qingyun needs now is to talk.

He suddenly broke into the vast world from a closed small world, and he would inevitably feel the impact of ideas and the confusion about the future.

He needs to talk and think in order to defeat his inner demons and find his own path.

"Most of the royal families of Wei Kingdom are short-sighted people. Now the King of Wei is committed to restoring the Han rituals, which is not a bad thing for the people of Jiangbei.

Besides, even if the King of Wei was assassinated, the Yuan family was full of talents at this time, but they would not fall.

But the Xianbei hatred and defense against the people of the Central Plains will be deeper, and it is meaningless to do so.

Today, I heard everyone talk about the civil and military romance of the young prince’s father Tuoba Meng, and I thought of my elder brother’s heroic deeds as he mentioned his father Tuoba Zhongkui’s heroic deeds. I’m afraid the same was true 18 years ago, right?”

Qingyun walked to the window, held the window threshold with his hand, looked up at the bright moon in the sky, his eyes reflected the stars,

"Why did my father take action back then?

Is he not seeing through this layer, or is there another reason?”

Xinzhi still had no answer.

He cannot answer these questions, and he should not answer them.

Perhaps Qingyun, many years later, will give himself an answer, and Qingyun will no longer be the confused boy who sighs with the threshold today.

Qingyun didn't mind seeing the sound of the slightest, knowing that he was too pretentious.

So I turned to a more down-to-earth topic.

“The three teenagers at the table today—

King Anfeng, your own family, Zu Ying, and Xindufang.

They are about the same age, three or four years younger than me, but they all look more persistent than me."

This time, Xinzhi was not silent. He knew that Qingyun's emotions had been almost vented, so he replied sneered,

"That's different. Fifth brother, I feel that your future achievements will be determined by the three of them."

"Oh? Are you coaxing me?"
