The drizzle drizzles and the falling silently.

The rain line fell from the air like ten thousand silver threads, and accumulated water droplets on the eaves, rolling down, as beautiful as a pearl curtain.

There was light fog in the mountains, and soon it enveloped the house. The white walls and green tiles, the red doors and green gardens were hazy, ethereal, misty, and long, much like a fairyland.

Countless tombstones and tombs stand in the rain and fog, appearing and disappearing, as if countless figures are coming slowly.

Will a ghost bride or a fox fairy suddenly appear from the fog?

Li Chengzhi stood in the attic with strange thoughts in his mind.

It started to rain at dawn, but it was not heavy, so the craftsmen did not stop working. The six pools had been dug, just waiting for the potter to burn the tiles and lay them out.

Seven or eight carpenters, with more than 20 apprentices and Lifu, planted piles and columns by three small ponds, and built gantry frames and poles. Some craftsmen were smashing the partition walls between the back garden and houses and re-standed them with purlin columns to support them.

After smashing the partition wall, the craftsman will dig deeper until water is dug out. The excavated soil will cover the exterior wall of the house. The roof will also be covered with two to three layers of wool-filled quilts.

The reason for this transformation is naturally to store ice.

Luoyang Xiao County has an official arsenal, as well as private weapons and iron tools workshops set up by Wang Yuanyong of Yingchuan, Wang Yuanji of Jiangyang, etc., so the iron box is not difficult to build and has been ordered. At the latest the day after tomorrow, the iron plates with ninety iron boxes can be transported back.

If nothing unexpected happens, it will be tested in three days.

The progress is indeed fast, of course it is because the money is spent: more than ten gold bars weighing a pound were removed.

Li Xie said that if the husband did not hurry up like this, he would save at least half of the money by delaying it by five or six days.

But Li Chengzhi calculated the account: if he sells it five or six days earlier, he can earn more than ten more gold bars...

"Mr., it's right at the Mao hour (6 o'clock in the morning)!" Li Rui reminded below.

"Yeah!" Li Chengzhi nodded and went down the attic.

There were only twelve retainers in Li Rui and Li Xieman, and there were not enough places to be busy with important things. How could Li Chengzhi let them drive the car?

In addition, Li Rui and Li Xie also wanted to use a car from time to time, so he simply rented one at the club. But it was really not cheap: it costs 1,500 yuan for the driver to take a car and horse in a month, which is 1,500 yuan.

Li Chengzhi, a seventh-rank official, had a monthly salary of only one thousand yuan, so he calculated that he not only did not make money, but also had to pay more...

Li Rui was carrying a food box, which was a bit like a small bedside table in later generations. There was two layers, one layer of rice and one layer of vegetables. There was also a leather bag hanging next to it, but it was not wine, but tea.

The coachman took the food box and leaned it into the corner of the compartment. In order to avoid falling, he tied it with a leather rope several times.

This is Li Chengzhi's lunch. When he is not in court, court officials above the fifth rank also eat this way, and they need to bring their own rice.

Of course, if you have good conditions, you can go to the guild hall and Lelou to book a meal. If you have poor conditions, there are many people who eat corn and wheat cakes every time.

Food is the most important thing for people, and eating is the biggest problem. Li Chengzhi pondered: "Let the mason build more stoves, pots, pans, vegetables, sauce, and grain... Well, the wooden bowl is tighter..."

Li Rui responded respectfully: "I know!"

Once the construction starts, there will be almost hundreds of guards and processing personnel, so these details must be considered in advance. Finally, the wooden bowl is for customers when selling smoothies...

The road was slipping slowly when it was cloudy, and Li Chengzhi didn't dare to delay too much. He gave a few words and left the door.

One mile south is Guangmomen, and when you enter the city and bypass the imperial palace, Tongtu Street, you can reach Taichang Temple in the south of the city, which is only a dozen miles away, which is very convenient.

Only Li Chengzhi did not have to go to court for the seventh rank, otherwise he would be closer. After this calculation, this house is really not expensive...

Although it was the first day he went to the yamen and the first day he became an official, Li Chengzhi's mentality was very calm.

Looking at the officials and officials walking in a chariot or riding horses on the Tongtu Street, which is more than ten feet wide, and walking in a straw raincoat, Li Chengzhi felt that it was no different from later generations.

Mediocrity is a lifetime, and a grand and vigorous life is a lifetime. Just live comfortably.

I had no choice but to do it, just like a dog chasing me behind my butt, I came to this point without realizing it.

All the fucked people, so I can only walk down with my teeth!

Li Chengzhi shook his head and withdrew his thoughts, and then considered how to make smoothies famous.

Whether the sales are good or not, publicity is the most important thing... so you must spend more time studying.

...

Emperor Xiaowen stipulated that one day was dying every three days and one day was dying every five days. In addition, the last day of the month will also be promoted. Today is thirty, and it is the sun, so Liu Fang and Cui Guang are naturally not in the Taishijian.

The Grand Historian Zhao Sheng was so busy that he could not touch the ground that he could not take care of a little Hou Xinglang. After he finished the Mao, he threw Li Chengzhi to the deputy commander and asked him to watch the arrangement.

The deputy commander was not like Zhao Sheng. He knew that he had been studying and doing research all day long. He knew that when Hou Xinglang was imprisoned yesterday, he was called by two ministers to ask questions, so he did not dare to make arrangements without authorization, saying that he would wait for Liu Fang and Cui Guang to come to court before asking for instructions.

Li Chengzhi had nothing to do, thinking that he could go to each department to see which one he wanted to do.

The deputy commander had no time, so he simply sent his subordinates to Li Chengzhi first.

The so-called subordinate officials are assistants, and every Hou Xinglang has them, also known as Hou Jun official. Li Chengzhi's surname is Geng. According to the deputy order, he was still the descendant of Geng Shouchang, an astronomer of the Western Han Dynasty?

The armillary sphere was invented by Geng Shouchang, and Zhang Heng of the Eastern Han Dynasty only made improvements based on it.

He also invented the Changping Warehouse System (Taicang in the imperial court, similar to the current China Grain Reserves Corporation), and also wrote "Nine Chapters of Arithmetic".

Speaking of this, we have to mention the "Heavenly Official" system in Chinese history where fathers die and sons inherit.

Most people think that Sima Qian passed on from his father and ancestors was a "historian", but in fact he was a "heavenly official", that is, astrology, and the position of cultivating history was just an accompaniment.

First, because this industry is not ordinary boring, and second, it is extremely profound. With this ability and patience, how many scriptures cannot be studied thoroughly? Why do you put the officials who are so comfortable and have more salary than this? Don’t be a job without dealing with a bunch of boring numbers and cold stars and moons?

Therefore, since the Qin Dynasty, most dynasties had laws: the Grand Historian, the Semi-Chief, the Di Guan, etc., which must be passed down from generation to generation. It is not allowed to study other scriptures, nor is it allowed to be other officials. This system continued until the Qing Dynasty...

This is how Gengchang's lineage was passed down. His father Geng Yan was the Grand Historian of Empress Dowager Feng. He was demoted because his divination poems were not in line with Empress Dowager Feng's wishes. Later, he died of depression.

Li Chengzhi was curious for a moment and asked more: "How dare you ask Ling Zunbu what he called him?"

Geng Chang looked at Li Chengzhi and sighed casually: "The way of heaven is fifty, and the earth escapes one..."

Li Chengzhi was stunned.

What kind of chaos shouldn't be: the great way is fifty, the heavens are four nine, and people escape...

Um?

Empress Dowager Feng...forty-nine?

Wouldn't Empress Dowager Feng live forty-nine?

Li Chengzhi's eyes burst: Why is Geng Yan so accurate?

Also, Geng Yan is too brave. He is indeed as good as his name. Even Empress Dowager Feng, who is not an emperor and is better than an emperor, dares to calculate the life span of his life?

I didn't think that Empress Dowager Feng was generous...

Muttering in his heart, Li Chengzhi asked Geng Chang to take him to various departments again.

The Taishijian divided the calendar and the Bu two ministers, and there are also:

The divination department, also known as Baozhang, determines good and bad luck by palms.

The Supervision Department, also known as the Calendar Department, is mainly responsible for calculating the calendar.

The Hou Department, also known as Lingtai, is the official who is the one whom the emperor granted Li Chengzhi, specifically for the divination calendar to observe the laws of astronomical phenomena.

The calculation department is specialized in verifying the calculation and verifying the data for the divination calendar. Most of the officials are doctors in the art of academia in the official schools such as the Taixue and Imperial College. When they are too busy, they will also bring students from the art of academia to help.

There is also a Si Shi Department, which is a palm leak carving, Si Chen, etc. (time, change, update, and alarm).

Li Chengzhi went to the calculation department first. As soon as he entered the door, he was stunned.

A large hall, nearly a thousand square meters, felt like he had entered a large banquet hall.

He was not surprised by the size of the hall, but the scene inside: there was a table in front of everyone that was larger than a snooker table, with hundreds of them placed. Each table was filled with calculations. Some were two or three hundred, and some were dozens.

The so-called calculation chip is a wooden stick, used to replace numbers. To put it simply: if a number is 6666, a horizontal wooden stick will first be placed on the single position to represent 5, and a vertical stick will be placed under the horizontal stick to represent 1. When it reaches the tenth position, it will be reversed. A firm stick above represents 5, and a horizontal stick below represents 1... Similar to this: 6666:T?T?.

Of course, the other way around is OK!

Only after setting up such sets of numbers will you verify it. A simple addition and subtraction method requires dozens of calculation pieces, let alone more complex multi-bit operations? So everyone has such a large table in front of them.

And it is not an ordinary trouble to calculate, especially when multiplication or division abdication, I forget that the horizontal stick that carries and abdicates is 5 or 1, so I can only recalculate it.

Li Chengzhi felt a toothache: If this is halfway, the bastard is idle or accidentally touches it, and brings the horizontal one into a vertical one, will the results of this day or even a few days be ruined?

Forget it, don’t deduce the Gregorian calendar first, what formulas to deduce, and then create the simple numbers first.

Otherwise he would be able to get himself confused.

There was nothing to read in the divination department, and Li Chengzhi couldn't understand it even after he went there. He asked Geng Chang to take him to the Housing Department to take a look, hoping to see what the Hou Xinglang, who was named by the emperor, originally did.

This is the only department that is not in Taichang Temple, but in Jinyong City near Mangshan.

Just because it's high here.

There is a tall building in Jinyong City, called the Hundred-foot Tower, which is about seven or eight feet tall, which is higher than the wall of the imperial palace.

It was also Cao Cao's grandson, Emperor Ming of Wei, who was originally for him to appreciate the stars and the moon.

Because it is too high and too close to the palace, there is a team of imperial guards below, and officials of the Taishijian are not allowed to enter.

Li Chengzhi had a token and had no obstacles to travel. He climbed thousands of steps and finally climbed onto the observatory.

Looking at the muscular elephant placed under the stage and the armillary sphere on the stage, Li Chengzhi took a breath of cold air.

The armillary sphere is not a wheel, just a muddy image: to put it simply, it is a huge copper ball, all of which are engraved on it are astrological phenomena that can be seen from the first day of the Lunar New Year to the 30th day of the twelfth lunar month.

The key is that this thing can automatically interpret the astrology throughout the year by just relying on the kettle to drive the gears, and it is not bad at all?

Li Chengzhi couldn't understand how ancient technology and productivity created such precision instruments?

And it was invented in the Western Han Dynasty?

Unfortunately, it is difficult to build clockwork, otherwise it would be easy to build a mechanical watch with this technology...

Can it be seen that the wisdom of the ancients is powerful?

This Hunxiang was invented by Geng Chang's ancestors and improved by Zhang Heng of the Western Han Dynasty. It was usually performed automatically when standing off the stage, and then Hou Xinglang and Hou Ministry officials were on the same stage, one was watching the stars and the other was watching the Hunxiang. While recording, they observed whether there was any error between the Hunxiang and the sky. This was the work that Li Chengzhi and his assistant Geng Chang should have done.

Whenever the dynasty changes, this thing will be lost, and often it is transformed into copper by the rebels, so the new dynasty can only be recast after the establishment of the new dynasty.

Even if you compare historical materials, the time to recast a mosaic is still planned in "ten years"...

It can be seen that the importance attached to the celestial calendar in all dynasties has led to the historical and cultural heritage of China for thousands of years.
