Zhuge showed no expression of joy or anger, which made Zhuge Fei's master and servant quite uneasy. Yunfeng secretly shook his head. He really didn't know how to evaluate this kind of well-behaved family of Confucian classics. Taking advantage of this time,

The rest of the people also met with Zhuge Xian respectively, and then Zhuge Xian welcomed everyone into the main room to serve tea.

After the guests and hosts were seated, Yunfeng seemed to feel that one person was missing, and couldn't help but poke his head out and asked: "Master Zhuge, why don't you see Mr. Fei?" Ji Wanwan, in addition to the improved double-entry accounting method, there is also the accounting you mentioned, General.

Equilibrium, as well as balance sheets, profit and loss statements and several other reports, this old guy has now gone to Shanggui and started training for tax collectors."

"Oh?" Yunfeng was overjoyed and quickly saluted, "Thank you, Tianjimen, for taking the trouble."

Zhuge Xian glanced at Yunfeng meaningfully, waved his hand and said: "Hey! This is nothing. Speaking of which, Fei'er is thanks to your care, General, during this period."

Yunfeng's old face was slightly red. He indeed took great care of Zhuge Fei. He took care of every part of his body. He glanced at Zhuge Fei unconsciously. Zhuge Fei also had a pink face and a bowed head.

Come down.

Zhuge Xian's tone showed signs of accepting the facts, but Yunfeng understood that it was not appropriate to talk about his marriage to Zhuge Fei on this occasion, so he could only say a few words in a humble tone: "Master Zhuge's words are strong." Then he asked again.

Xiang Qiaoxiu: "Teacher, my disciple, it seems that you and Master Zhuge... have known each other for a long time?"

Qiao Xiu showed a trace of weirdness. He shook his head and said: "Back then, Li Xiong had never entered Shu, and he lived with Master Zhuge in Chengdu as his teacher. We had met several times, but we two old guys got together.

Nothing but quarrels."

"Huh?" Yunfeng cast his doubtful eyes over him, and everyone in the hall looked back and forth between the two of them curiously.

Zhu Ge

Lift it, turn around and leave! From now on, I will never interact with me again! It has been more than 20 years since I last met."

Yunfeng wondered: "Why is this?"

Zhuge Xian did not answer, but asked: "Has General Yun ever dabbled in celestial phenomena?"

Yunfeng pondered: "It's not far from dabbling, I only have a smattering of knowledge. Nowadays, the two mainstream theories are Gaitian theory and Huntian theory. Among them, Gaitian theory has the greater influence!"

The theory of Gaitian advocates that the celestial sphere is semicircular and covers the ground. It was first seen in the "Zhoubi Suanjing". It is the most intuitive perception of the universe by humans. Its greatest contribution is to determine the four phenomena of southeast, northwest and northwest. The theory of Huntian was perfected in the Han Dynasty.

Zhang Heng believed that the sky is like a chicken's egg and the earth is like a chicken's egg. He advocated that the celestial sphere was round and wrapped around the ground, which was a further exploration of the universe. Some people in later generations believed that

The theory of Hun Tian is equivalent to the ancient Greek theory of a round earth, which is really a misinterpretation. The essence of the theory of Hun Tian is still that the sky is round and the earth is flat. Whether it is the theory of Gaitian or the theory of Hun Tian, ​​their ideological foundation is inseparable from the ancient Chinese theory of yin.

The Five Elements of Yang, when applied to political life, are still the same as Yang is noble and Yin is low, and the ethics of ethics are the same, and this is exactly the ideological system that Yunfeng wants to overthrow.

Qiao Xiu nodded on the topic: "What Duan Shan said is right. My master advocated Gaitian Theory, but Zhuge Sect Master insisted on Huntian Theory. This is also the reason why the two of us started quarreling when we met. For a while, no one could do anything.

who."

"Hehehehe~~!" Zhuge Xian smiled confidently: "Old Master Qiao, I am not boasting. This time you have to surrender."

"Humph!" Qiao Xiu snorted coldly, with a look of disdain on his face.

Zhuge Xian stood up and gestured: "You don't believe me, Master Qiao? Please come with me and take a look and you will find out! General and you, if you are interested, you may as well come with us." After saying that, he waved his sleeves and walked out.

Everyone looked at each other, including Qiao Xiu, and all followed suit.

Soon, Zhuge Xian arrived at a large house in the backyard. This large house only contained two instruments, one of which was connected to a water canal. There were movable windows on the roof, and there were no other furnishings.

.

For a moment, Qiao Xiu's face was extremely ugly, and she said in disbelief: "You...you actually restored the armillary sphere?" The armillary sphere made by Zhang Heng was destroyed in Dong Zhuo's rebellion in the late Han Dynasty, and the method was lost after that.

No one has been able to successfully restore it, and only fragments of it remain in historical records. No wonder Qiao Xiu was so shocked.

Zhuge Xian stroked his beard and smiled slightly, but did not answer. Obviously, Qiao Xiu's gaffe made him very happy.

And everyone came forward to watch. The armillary sphere was made of brass and was divided into two parts: the inner and outer weights. The outer weight consisted of three large intersecting rings forming the skeleton of the armillary sphere, and was supported by four pillars. The inner weight was fixed on the frame with a removable shaft.

The double rings are rotated, and the diameter of the double rings is eight feet. A tilting telescope is sandwiched between them, and the length is also eight feet.

The other one is smaller in size, with a diameter of two feet and two inches. It is also made of solid copper. It wraps the ground plane with a big ball. At the same time, the ground plane divides the big ball into two, half covering the ground and half submerging the ground.

It is decorated with astrology, and the zodiac is decorated with the sun, moon and five stars.

Seeing these two ring-shaped instruments, Yu Wenjun pulled Zhuge Fei and asked in a low voice: "Sister Zhuge, do you know what they are used for."

Zhuge Fei smiled apologetically: "Sister Wenjun, you are embarrassing my sister. I don't understand the astronomical phenomena, so I can't answer you."

Only then did Yu Wenjun realize that Zhuge Fei was blind. If he could observe celestial phenomena, it would be really sensational. He couldn't help but feel secretly impressed, and wrapped his arms around Zhuge Fei like a baby.

"Girl of the Yu family, you don't understand?" Zhuge Xian was very interested and took the initiative to explain: "Girl of the Yu family, please take a closer look. The rotating axis of this armillary sphere located inside the center is one for the celestial north pole and the other for the celestial south pole. It can be easily measured.

The equatorial coordinates of a celestial body.”

As he spoke, Zhuge Xian pointed to another smaller instrument: "This is the Hunyianxiang, which is located in the twenty-eight constellations of Chinese and foreign officials. The white, black beads and yellow three colors are the three stars. The so-called three stars are Gan, Shi, and Wu Xian."

The star meridian is driven by water power, and the stars in the middle of the night correspond to the sky.

The muddy image is not only used to demonstrate changes in celestial phenomena, but is also an indispensable tool for studying the movement patterns of the sun, moon and five stars. In short, based on the actual observed positions of the sun, moon and five stars relative to the surrounding stars, the sun, moon and five stars can be accurately distinguished

Place them at different parts of the ecliptic, and then by continuing to observe them, you can understand their movement patterns relative to the stellar background, and thereby calculate the synodic period of the planets, and so on."
