Wei and Jin cooks

Tinghe walked in quietly, lit the candle, and the space suddenly became bright. Only then did Zhao Hanzhang realize that the sky had started to darken at some point.

She rubbed her slightly sore eyes and warned herself not to indulge in entertainment.

Yes, these funny letters are really entertaining.

Zhao Hanzhang put all the letters away, then went to touch the official documents. He looked up and saw Fu Tinghan diagonally across the street writing something with his head down. He didn't look up for a long time, and he didn't even light a lamp to disturb him.

Zhao Hanzhang couldn't sit still anymore. Just like a child with ADHD, he got up and walked over there.

She walked behind him and looked around, and saw that he was drawing a picture on a large piece of paper.

She was a little surprised, "This is..."

Fu Tinghan came to his senses, put down his pen, and said with a smile: "These are the simple instrument and the vertical movement instrument. Since the armillary sphere is gone, there is no need for us to make another one exactly like it. We can just simplify it."

"The armillary sphere originally has multiple structures, including the zodiac ring, the horizon ring, the meridian ring, and the sextile ring, the bipartite ring, and the two solstice rings... When these multiple ring structures are assembled together, the overlapping centers will produce a large center difference. Moreover, each ring will cover a certain area of ​​the sky, and the observation deviation will be very large, so I think it is better to simplify it and eliminate the need to do some things that can be calculated using arithmetic."

Zhao Hanzhang: "For example?"

"For example, the white ring can be eliminated, and the position of the moon can be completely calculated mathematically," Fu Tinghan said: "I talked with Guo Pu. Through such observations, the calendars and lunar calendars we make can be infinitely close to nature."

Zhao Hanzhang was amazed, nodded and said: "Then make it, I'll have someone prepare the materials."

Fu Tinghan made a list for her. This thing is difficult to make because not many people know about it and can do it even less. There are so many rings. Just installing them requires a lot of calculations, and the technical content of the peep tubes is also high.

Oh, this viewing tube is equivalent to an astronomical telescope, which can measure the equatorial coordinates of stars and celestial bodies in various time periods, as well as the ecliptic longitude and horizon coordinates of celestial bodies.

Fu Tinghan believes that he can slightly improve it so that it can see more clearly and see more.

This thing is not difficult to do because it can be achieved with current technology and materials.

Zhao Hanzhang took the order and readily agreed, "It's not difficult, I'll have someone prepare it for you."

Seeing how easy it was for her, Fu Tinghan said: "Then...make another Hunyang? It's just for demonstration."

It's like, that thing only uses a lot more copper, Zhao Hanzhang was stunned.

Seeing her like this, Fu Tinghan tried to persuade her, "Guo Pu would be even more reluctant to leave if he saw that we were in trouble."

Just thinking about it made him reluctant to part with it.

Fu Tinghan looked up at her with bright eyes.

How could Zhao Hanzhang refuse under his gaze? He couldn't help but nodded, "Okay."

Fu Tinghan couldn't help but laugh, and immediately took the list in her hand to add the material for Huxiang. When she saw that he added the required copper weight on it without hesitation, she knew that he must have finished it long ago. Huxiang needed copper, but because she was poor now, she didn't mention it before.

Zhao Hanzhang took the order and sighed, "In the past, because our territory was limited and our money was lighter than others, we were afraid that the word 'Zhao' would ruin the market, so we had to calculate it carefully every time we made money."

"I'm not afraid now. Not only because our territory is large, but also because our power is stable, and the purchasing value of the 'Zhao' money is also stable. However, now I find that there is not enough copper." She sighed deeply: " We still have too little copper discovered now.”

It was only after she formally took over the government that Zhao Hanzhang learned that the imperial court's official money was not enough every year. In places where she could not see, the money was not circulated enough, so silk, cloth, and grain were all used as money.

This is not only the case in the north of the Central Plains, but the situation in Jiangnan and Jiangdong is not much better.

Yuanli Bao said that in a small coastal county, a kind of shell was used more than copper coins.

When she received this information that Yuan Li told her as a joke, she almost suspected that she was not in the Wei and Jin Dynasties, but in the Shang and Zhou Dynasties.

In the final analysis, it is still because there is too little copper.

But she didn't dare to use other things to replace copper. It was too dangerous, at least not suitable now.

There are hundreds of kilograms of copper. Let's get it from the nearby copper mine in Luoyang.

Zhao Hanzhang decided to fold up the list and put it away. It was not worthwhile to go to Chang Ning just for this matter. He might as well mention it to him when he saw him at the palace banquet on New Year's Eve and let him prepare as soon as possible.

Zhao Hanzhang turned around to go back to approve the official documents. He caught a glimpse of a dozen neat official documents piled beside his table, and paused in his steps, "Have you finished approving them?"

Fu Tinghan nodded, "It's approved."

Zhao Hanzhang was jealous and immediately said: "Help me calculate some things."

Fu Tinghan smiled and went over to help her calculate. Sure enough, with the various figures he calculated and the figures reported in various places in his mind, it was easier for her to make judgments and she could reply to official documents faster. .

Fu Tinghan saw that she had finished approving a book and handed it over to her.

Zhao Hanzhang pushed the approved official document aside, took it, opened it, scanned it ten lines at a time, and wrote a reply within a moment.

Fu Tinghan waited silently for the previous book of ink to dry, closed it and folded it aside, then sat opposite her to grind the ink for her...

The two worked overtime until late at night, waiting for Zhao Hanzhang to finish processing all the official documents and letters before braving the cold and going back to the house.

Fu An and Ting He both slept by the stove in the side room. When they heard the sound of the door opening, they woke up immediately and trotted out.

Zhao Hanzhang turned his head and looked over. Seeing the marks on their faces, he couldn't help but laugh out loud and waved, "You don't have to guard them from now on. Go and have a rest early."

Fu An was going to light a lantern for them. Zhao Hanzhang had already raised his hand and took out a lantern from under the eaves and handed it to Fu Tinghan. Fu Tinghan hung it on a stick. Fu An recognized it and used it to light the map. Used it, and occasionally used it to beat Zhao Erlang. His eyes widened.

Tinghe went back to the house and brought out two cloaks.

Zhao Hanzhang took it and said to her: "You just woke up, please keep warm. We have put out the fire in the study, and you have to put out the fire in the side room before going back."

Without letting them escort, Zhao Hanzhang and Fu Tinghan put on their cloaks and went back by themselves holding lanterns.

The cold wind was blowing, and Fu Tinghan couldn't help but hold her hand and said to her: "The main courtyard is still far from the study, so I should have arranged it next to it."

"The working and living places should be separated," Zhao Hanzhang said with a smile. "But now that it's cold, I really don't want to walk too much. I'll ask Tinghe to clean up the side room of the main courtyard to make a small study. In the future, I can add small classes in the small study." ."

Zhao Hanzhang didn't know how other officials celebrated the New Year. Anyway, while she was waiting for the New Year, she still had official documents and letters to approve every day.

But not all official documents and letters were answered by her. For example, she temporarily put aside the letters and official documents proposing that the court offer sacrifices to heaven.

What kind of sacrifice should be made? The little emperor is not in charge of the government now, and secondly, he has no money. I wonder if the rooftop sacrifice platform was burned down by the fire. Do I need to build a platform if I want to worship heaven?

If she had the money to build the rooftop for worship, would she not have the money to build the star observatory?
