"Let's go two days! When we inform Tiande, we will transfer the blue jade to leave Beijing!" Zhu Yuanzhang said with a smile.

In such a hurry?

Queen Ma frowned: "Chongba, Lan Yu has been fighting with the army in the east and west all these years, and she has gathered less with her family and left more. In a few days, it will be the annual Zhengdan Festival, so why not let Lan Yu celebrate the Zhengdan Festival and go to Beiping again."

"We have our own plans for this, so you don't care!" Zhu Yuanzhang snorted and said.

Jin Yiwei is investigating Lu Zhongheng and others' involvement in Hu Weiyong's case, if it is just chasing after the wind and shadows, there is no empirical evidence. But once the investigation reveals that Lu Zhongheng and others are involved in the Hu Weiyong case.

Then he will inevitably go on a killing spree and purge the nobles.

He didn't want to see Lan Yu and run to him with Lan Bin to plead, and he didn't want to see Lan Yu involved.

"Even so, then I won't ask!"

Queen Ma looked at Zhu Yuanzhang, didn't ask more, changed the topic and talked to Zhu Yuanzhang for a while, and left the Qianqing Palace. ………

"Cousin, you don't know how anxious I was when I received a letter from you looking for someone. At that time, I dragged the imperial grandmother and trotted to the Qianqing Palace to save you..."

On the way to the main hall, when Zhu Xiongying was chattering, he saw Lan Bin's absent-minded appearance, stopped again, and said curiously, "Cousin, what are you thinking?"

"Didn't think about anything, you go on!" Lan Bin shook his head.

He had been thinking about copying the Analects and giving Zhu Yuanzhang an errand, but he hadn't had time to think about Zhu Yuanzhang's punishment for copying the Analects.

And now that he is copying the Analects, the matter of the errand is considered to be in the past, and he finally has time to sort it out before and after, thinking about Zhu Yuanzhang's punishment for copying the Analects.

Thinking about it carefully, the more he thought about it, the more he felt that Zhu Yuanzhang's punishment of copying the Analects was not for no reason, but because it had a deep meaning.

It's just that for a moment, he couldn't understand the deep meaning.

Zhu Xiongying looked at Lan Bin suspiciously, didn't ask more, and continued to ask him about inviting Queen Ma to the Qianqing Palace, and after talking about it, he suddenly remembered the quill he had seen in the Qianqing Palace.

He said with great interest, "Cousin, did you really make the quill? How did you come up with the idea of making a pen out of goose feathers? Do you have any extra quills anywhere? …」

"Stop, I still have a quill here, you can play with it!"

Lan Bin's mind was swollen when he was asked, and he hurriedly took out a quill from his long sleeve and handed it to Zhu Xiongying.

Zhu Xiongying took the quill pen and played with great interest, before this, he never imagined that such a small goose feather could be made into a pen to write.

And now, if he hadn't just seen the appearance of a quill pen, he would only regard the quill in his hand as a cleaned, relatively clean goose feather.

Lan Bin saw that Zhu Xiongying's attention was attracted by the quill, and breathed a sigh of relief, Zhu Xiongying's questions, let him answer, he really didn't know how to answer.

It is difficult to tell him that he came from later generations, and the quill is a writing instrument invented in Western countries.

Not long after, Lan Bin and Zhu Xiongying came to the main hall, and when Mr. was not there, all the princes and grandsons gathered around, and they were concerned about Lan Bin's copying of the Analects.

Every word you say to me makes Lan Bin's brain hurt.

"Thank you for your concern, I'm fine!"

Lan Bin waved his hand, and after a simple and selective talk about the affairs of the Qianqing Palace, he sent away the princes, sons and grandsons.

Zhu Xiongying originally wanted to show off the quill in his hand, but unfortunately Mr. arrived at the main hall at this time, so he could only press the mind of showing off the quill pen, carefully put away the quill and concentrate on studying.

At the beginning of the afternoon, the main hall got out of school, and Lan Bin said hello to the princes and grandchildren as soon as possible before Zhu Xiongying showed off his quills, and hurriedly left the palace and returned to the Lan Mansion.

Arriving at Lan Mansion, Lan Bin gathered the people involved in the production of quill pens and began to make quill pens on a trial basis.

The reason why it was a trial production was because he had made a quill pen to copy the Analects, and the time was very tight, and the procedure for making a quill was relatively rough and immature.

He uses it himself, so naturally he doesn't have to think about it so much, just make a quill pen. But if you want to write a piece and submit it to Zhu Yuanzhang, the quills production method needs to be reformulated.

In particular, it is a production method that is easy to promote. Look at the book

It's like crystallizing the scientific research in the laboratory, making it factory, and scaling it up.

Of course, the quill is just a small object, and the production is not so complicated, but to make it an assembly line product, it needs to be re-straightened out and recorded in the production process.

Two days passed in a blink of an eye, and under the guidance of Lan Bin, people made quill pens, and finally summed up a set of quill making methods suitable for promotion, and then went to the palace with the recorded methods.
