"Master !!!"

Liu Chang's very personal voice passed through the door and passed directly to Zhang Cang's ear. Zhang Cang, who was writing, heard the sound, was so scared that he was a little unstable, and his body trembled.

At a moment, he quickly calmed down, Zhang Cang put down his pen calmly, sighed, sighed before ending, Liu Chang appeared in front of him in a hurry, Liu Chang smiled, and he mentioned it in his hand.

Following gifts.

I do n’t know where Liu Chang came from this gift. Zhang Cang's family had no gift anyway. Liu Chang had been cleaned by Liu Chang for a long time, and there was nothing left.

At the moment Liu Chang started, Zhang Cang stopped the editing of the calendar. As long as there was this vertical man, don't think about what to do.

Liu Chang disappeared, put down the gift, sat in front of Zhang Cang with a smile, lowered his head, and looked at the information he recorded. Zhang Cang had deep research in the field of astronomy, and because he was proficient in mathematics, he was proficient in mathematics.

Become the best candidates for the editing calendar, and the things that other records recorded are exactly some of the astronomical information.

"Teacher, I know that you have been busy because of the calendar in recent days. There are no children who have given birth to children. I deliberately brought you some supplements. You see, this is all of them, all of which are the best.

Xia Wu and things that are used on weekdays "

Zhang Cang pursed his lips, and the source of the gift was clear.

"Her Majesty is going to see Xia Wuxi?"

"Yeah, this old .. Mr. has been admitting to the illness at home, and I had to go to the view in person. As a result, he was not in Changan.

Zhang Cang ordered a son to accept the gift and thanked the emperor for their care. Then he asked his purpose.

"I heard that the calendar is difficult to formulate. You have selected more than thirty people in person and followed you to watch the phenomena of the night. It took a long time and never made progress.

For more than fifty years, it can be regarded as a fire. This time I came to help the teacher to make a method. "

Liu Changgao raised his head and looked at him like this, as if he was on Zhang Cang, and he had to thank Zhang Cang for his guidance.

Zhang Cang knows the virtue of his disciple. Although he is not learned, he does have a good talent in mathematics and other aspects. Perhaps, he does have some results in astronomy?

When Zhang Cang saw him so confident, he showed him what he recorded. Liu Chang took his record, looked at it seriously, nodded his head from time to time, and thoughtful.

Zhang Cang was really surprised this time. His Majesty can really understand ?? You know, this is Zhang Cang's record of the operation of the celestial body, and at the same time, there are calculation formulas.

It was the middle of the night of Jiazi Sun in November of a certain year. It happened to be Shuo and the winter solstice, and it was the time when the month was too close. Then the formula was introduced.

The monthly time, the unit is all heaven, and also sets Y as the cumulative year of the year from the end of the year.

In this way, AY has been the whole time of the winter solstice of the year from the Yuan Dynasty.

With Liu Chang's ability, it is not difficult to understand the formula. What is really difficult is that the celestial body is running, such as the seven politics and five times, twelve times, and the wild.

I do n’t understand, and Liu Chang is looking at those things very seriously.

"What do you think of your Majesty?"

"Good words"

The expectation on Zhang Cang's face suddenly disappeared.

I shouldn't have any great hope for this vertical child.

Liu Changqing cleared his throat and put the things in his hand aside, "Master, can you get a pen and ink for me?"

In front of Zhang Cang, Liu Chang once again performed his wonderful painting skills, the earth, the earth, the moon, including the sun, and the surrounding planets. Anyway, you can probably see the order.

Turning around the earth, the earth is surrounded by the sun and turns, so there is a day and night alternation, and the four seasons will be changed. All your calculations must be pressed by this, otherwise it is wrong. You have written so many times.

Furious? What is this? "

"Surging is fascination"

Zhang Cang thought for a moment and explained: "It's a star, it's like a fire"

"Is Mars?"

"ah?"

Liu Changfan touched his chin, "So, I still have to make a telescope first, so that you can explain it clearly with you, otherwise, you can’t understand it at all!"

Obviously you don't understand.

Zhang Cang sighed, "Okay, please do it to do it, and the minister continues to study these"

"Teacher, don't be so disappointed, I didn't lie to you. All I drew just now is right. Anyway, when an astronomical mirror comes out, you can know.

The ancients said 360 days a year. It is wrong. Do you know? "

"Chen knows that the court is calculated for 366 days a year."

Liu Chang was stunned, and he looked at the teacher in front of him. To be honest, sometimes he really admired his teacher, not only the teacher, but also those past mathematics. These people are really amazing.

With the simplest tools, the calculation is so accurate. Although there are still some errors, there is no way. Who can do this point without any instruments?

"What's wrong?"

"No hindrance, wait for me to make the tools, and the crickets don't have to be so painful."

Liu Chang did not have the arrogance of the only way. He said very seriously: "Teacher, you can rely on today's tools to do this. You can be regarded as God. I did despise this calendar. I will go for you now for you.

To solve this problem, and wait for more useful tools to appear, you don't have to close yourself. Calculate your head here day and night. At that time, everything will become much easier. "

Although I don't know why Liu Chang became so serious, he could feel the disciple's concern. Zhang Cang was still very happy. He nodded gently, and then said, "However, you should not be too anxious.

I also know how hard the success of successful inventions, which is not easier than my calculations. As the emperor of the big man, there are many things to do, and it is a serious ill

"

"No hindrance, teacher, even if it's exhausted, I must succeed !!"

"I will never give up !!!"

Liu Chang gritted his teeth, and he vowed very seriously.

"You have to do this thing for me. If you can't do it, don't want to do other things !!"

Liu Chang was sitting in Shangfang Mansion and pointed at the design drawing in front of him, and his attitude was extremely determined.

Chen Tao silently stood in front of Liu Chang, lowered his head, and glanced at what Liu Chang wanted to do, new glazed, many people talked about glass, thinking that this was a modern product.

There are glass. The glass appeared very early in Huaxia. It was called Liuli. Later, because the name was unknown, it was changed to glass. However, the ancient glass was different from today.

Some meaning.

And what Liu Chang is doing today is made up of Liuli. According to the emperor, the current Liuli cannot meet his requirements.

To do it, Liu Chang just told Chen Tao, "The stone is quality, the nitrics are harmonious, the reefs are used, the copper, the iron, and the Dan lead will change."

Couguang relying on such a sentence, let yourself make a brand new glazed. This is a bit too big. You have to tell me the proportion.

Production method, what should I do?

Chen Tao's eyes were a little blank. He looked at the content of the paper repeatedly and raised his head again.

"Your Majesty. This is really a bit too too."

"How can I do it? Do you know how tired Zhang Xiang is? He worked hard all day and was busy calculating the celestial body. This thing was made.

The usage is diverse. It can be used in military. This new Liuli can also be used as a decoration. Why do you have a little ambition? "

"His Majesty. This is not a minister who dare not do it.

"Did you tell you all? First of all, we put an appropriate amount of tin lead in the iron plate and burn the same lead together, mixes full when burning, and add a little bit of sand, that is, sandstone, that is, sandstone, that is, gravel

Gour into thinner powder, and then pour them into a tank made of soil. In the next twelve hours, you have to add the nitrate of the same amount as the sand. "

Chen Tao's face is very bitter, "a good minister must do well."

"Don't put on this expression either. Look, now your food has more than 5,000 households. If you can develop this thing this time, you can at least add a thousand households.

Many ministers in China have become the real big and thorough Hou. That Zhou Bo's food is not as much as you. You have to do it with your heart. Look at the today's Mojia, the Gaojue position is a big grasp, and the Mo family starts.

Take the elite route, each of which is the Confucian that adults usually abuse you, and now you see you only have salutes. "

"You have to think about the Mo family, you have to think about your own title.

"The people of the big man are suffering, do not cover your body, and don't eat your belly, because there is no such glazed."

For His Majesty's words, Chen Tao had been used to it for a long time, and even recited it. Anyway, no matter what His Majesty let himself do, he said that this is what the people are urgently needed.

What does it have to do with the people? Of course, Liu Chang can always associate these things without relationships, and Chen Tao didn't ask much.

Although His Majesty is mostly fake, there are also true.

The continuous improvement of his title is true. The invention of these years has made Chen Tao's continuous promotion, which has become a Daqian of 4,800 households. None of the entire Changan can be compared with him.

After crossing the battlefield, he got so many titles. He was a big man, and even the status of the entire Moho family was rising.

Opposing technology is just opposed to these craftsmen's status more than themselves.

The Mo family almost took root in Shangfang. Under Chen Tao's operation, it became more and more strong. Although the number of disciples was very small, they were ashamed and embarrassed on weekdays.

This has also become a national high -end doctrine for the country.

At this moment, the emperor asked them to do everything. Regardless of the result, Chen Tao had to grit his teeth to do it. Is it unfortunate that he was lucky? But, who can make people be the country?

At such a big age, although he looks more strong than himself.

After instructions, Liu Chang returned to the palace after driving.
