Da Shou Mountain, view of the roof.

The night of July 17 in the second year of Zhang Wu was particularly bright, and Chen Guotai Shi ordered Hu Qian to bathe in incense and start work after straightening his clothes.

His job is also simple, which is to lie under the telescope and watch the night sky, and make a record of the stars of the day.

Crystals are not difficult to find, Tian Xin's own eyesight is extraordinary, and he doesn't need crystals to make telescopes, but when he polishes the crystal goggles for the helmet, he polishes them by the way, and it takes a lot of effort before and after to make a telescope.

Through basic optical knowledge, this telescope is like an artifact in the hands of Hu Qian, which can be used for ranging and leveling.

A suspended model of the orbit of the solar system hangs in the pavilion of the observation platform, and Gu Qian, who came here, understood the principle of solar and lunar eclipses...... It's crazy.

Since Gu Qian, the old immortal of Langya Dao, went crazy, Da Shou Mountain has become a forbidden place, and only Hu Qian and Meng Guang are active here.

In the middle of the night, Hu Qian finished taking notes and changed shifts with Meng Guang, who was responsible for the astrological observation in the second half of the night.

Telescope...... The Sky Viewing Mirror is really a humane artifact, and handing it over to a martial artist to fight is really a tyrannical thing!

Meng Guang is a person who can't be idle, and he has just woken up, full of energy, and chattering: "Mortals are mediocre, I'm afraid only you and I know that Chen Gong's weapons are magnificent." It's ridiculous that the father and son are proficient in astronomy, and the family is known for their ability to interpret the book of Tuluo. ”

Hu Qian sorted out the documents of his previous observations, and did not raise his head: "He seems to have impeached Beifu recently?" ”

"This is indeed the case, because Chen Gong ceded the twenty battalions and merged them into the guards, and it seems that this is a public move."

Meng Guang didn't have any good words on his lips, he was a person who governed the Ram Spring and Autumn Period, and he looked down on the people who engaged in the Zuo Spring and Autumn Period, and he also looked down on the people who were engaged in Shangshu.

What is Shangshu?

Shang, Shang, Shang, Shang, the Book of Ancients; What is Book? The historical materials recorded in the book are books.

If the Six Classics are all history, then the Book of Books is the history of antiquity.

In this way, we will be able to look at and analyze the history contained in the Six Classics with an equal eye; If you look at the Six Classics in terms of the classics, you can only look up and either kneel down to read them, or bow down to look at them...... It's hard to question what the predecessors said.

There are many people who have passed down the book of governance, which is a very difficult classic to understand, and it is really too many chapters that have been lost in the process of inheritance.

But Tian Xin mastered Hetu and Luoshu, and the person who taught Tian Xin also deduced Taijitu and Sanba Tu through Hetu Luoshu...... Will this lead to academic flourishing?

Yes, there are so many positive meanings that make the current generation have something to study.

At the same time, it also discredited the family of Zhishangshu, for example, Qian Zhou, who was originally going to recruit as a doctor through the 'Ming Jing' channel, was simply defeated in the booing, and was changed to 'Founder' to enter the office and recruit as a speaker.

It is not only the Zhou himself who is affected, but also the reputation of the Zhou family's family Zhishangshu, which is considered to be broken, and it is difficult to gather again.

A Taiji diagram made Qian Zhou stand on the opposite side.

Hu Qian and Meng Guang chatted word by word, and Meng Guang suddenly mentioned something: "The Rui beast raised by Taifu was copied into the forbidden, and I heard that nearly half of them died...... This is not a good omen. ”

Hu Qian was stunned and speechless, and Meng Guang said again: "This year, the imperial court has the battles of Jiangxia, Jiaoguang, and Nanzhong, and I am deeply afraid of it. ”

As he spoke, Meng Guang looked down at the stargazing tower under his feet, and the model that Tian Xin called the sun's star track was hanging in the building.

Compared with the defeat of the Han army, the things hidden in this building are enough to subvert the current doctrine and cognition.

An example of a madness like Gu Qian...... Definitely not a lot.

The more you know, the more you understand, and the more you will be impacted.

Yu turned and failed to see this set of sun star tracks before his death, which can be regarded as Tian Xin's regret, which has become a nightmare imprinted in the hearts of Hu Qian and Meng Guang.

Taoism, learning, and law...... Compared to these things, it is not worth mentioning.

In the past, there was a dispute over snails and horns, how similar is it now?

Hu Qian still didn't answer, and returned to the downstairs house with his observation data.

After he left, Meng Guang let out a long sigh, looked up at the bright moon, his eyes were cold, he had lost his earlier good expectations for the sun and moon, and the sun and moon had no sacredness at all.

The sun and the moon are like this, the mountains and rivers are like this, and so are the gods.

Independent stargazing building, boundless panic surging from all directions, wanting to engulf itself.

Force yourself to concentrate and think about the war from the perspective of a bystander.

The current Han army is too floating, and after successive victories, it even wants to open up three battlefields to attack at the same time, and a very important primary and secondary contradiction has begun.

First of all, Yizhou's supplies will be put into the Nanzhong battlefield; And should the materials of Jingxiang and Xiangzhou be supplied to Tian Xin or Guan Ping first?

To Tian Xin can successfully pacify Jiaoguang Erzhou, and to Guan Ping can control Jiangdong's throat when Sun Quan is weak, laying the foundation for the destruction of Wu in World War I.

Tian Xin and Guan Ping started war here...... Then we will be able to deal with the South China issue by political means, and the South China will be able to resolve it peacefully.

However, I am afraid that Nanzhong Haoqiang will misestimate and think that the Han army will launch two wars and cannot use troops in Nanzhong...... Then Nanzhong Haoqiang will respond to Zhuge Liang's political methods with a tough attitude, and Nanzhong Haoqiang will take the lead in rebellion and the Nanzhong War will occur.

That's right, the outbreak of the Battle of Nanzhong, not surprisingly, should be a strong rebellion and the Han army quelling the chaos; It was not the Han army that took the initiative to advance, forcing the strong rebellion in Nanzhong.

It's one thing to look at, it's actually two different things.

In the case of the former, it will be a just counterinsurgency war that will not have a negative impact on other tribes.

The latter's words, just like Wu Zhen's backstabbing and attacking and destroying the five tribes of the Southern Xiongnu, seemed to be a temporary victory, but it made Wei lose its diplomatic credibility in the eyes of the nomadic tribes.

From the perspective of the emperor and the prime minister's office, the battle of Nanzhong is actually more inclined to a peaceful solution, or a quick victory.

In order to save military consumption, more resources will be transferred to the Guanlong battlefield.

If the battle between South and China is fought for three or five years...... Then don't think about continuing the Northern Expedition.

The situation is clear, but there are few people in Nanzhong who can see clearly, they only care about their own half-divided and leisurely life; Lack of interest in the world outside Nanzhong, no matter whether Liu Zhang or Liu Bei dominates Yizhou, as long as it doesn't hinder the life of Nanzhong.

Meng Guang's mind became clearer and clearer, and he saw the situation more thoroughly...... The clearer Tian Xin's terrible.

Not to mention anything else, if Guan Yu is allowed to come here, he can see the sun and star orbit...... Guan Yu is not crazy, he will be abandoned for a long time, and he will even burn down the stargazing tower with a fire, so as not to poison the world.

It is simple to burn down the stargazing tower, anger Tian Xin, and then throw out other terrible things, that ......

Unbelievable, Meng Guang's heart was full of worry, and he felt that countless fearful thoughts in all directions were eroding his hairs, trying to drag his mind into another dark world.

He held the mirror of looking at the sky, his mind did not belong, and he only felt that he could not recognize himself clearly.

Are you a courtier of the Han family? Or is it a person, or something else?

The quiet night sky gradually turns blue, the distant sky rises orange and red, the morning glow gradually dyes red, and the sound of roosters also enters the ears.

Meng Guang's hands and feet were stiff, looking at today's record book in a daze, he didn't know what to write, he felt that his mind was eaten away by fear, and he was left with a bare head.

Thinking of Hu Qian again, he might have to change shifts with Hu Qian, and he would be on duty in the first half of the night.

Otherwise, I am afraid that I will go crazy.

A group of schoolchildren should also be recruited...... Only schoolchildren can adapt to this, and if they recruit other astronomers, they will probably be covered with fear, sorrow, self-blame, and guilt for the rest of their lives.

Maybe one day he will suddenly go crazy and die of terror, and be found by Hu Qian, lying on the top of the stargazing tower in an embarrassed posture.

Meng Guang put away a pair of dark circles under his eyes, put away the sky viewing mirror, dragged his stiff body back to the house, and fell asleep on the bed amid the sound of roosters.
