Early the next morning.
After finishing the boxing breakfast routine, Zhu Biao started studying again.
With yesterday's theoretical foundation, today's content is much simpler.
After explaining the knowledge about focal length, all that is left is to polish the glass by hand.
Su Jing very thoughtfully prepared all kinds of polishing and polishing tools, leaving everything to Zhu Biao to operate slowly.
"There is no shortcut for polishing this step. I just need to slowly try and find the most suitable focal length."
Su Jing said to Zhu Biao: "You may fail many times, but I believe you can do it."
Zhu Biao nodded seriously and said: "Master Su, don't worry, students are not afraid of failure."
Necessary encouragement is still needed. After Su Jing finished explaining, she no longer stayed with Zhu Biao.
Everything that needs to be taught has been taught. Whether it can be done depends on Zhu Biao himself.
As for Su Jing, he also has his own things to do.
In the southernmost part of Lishui County, Su Jing was inspecting a papermaking workshop on the bank of the river.
Papermaking has been around for a long time. Cai Lun of the Eastern Han Dynasty used bark, hemp heads, rags, fish nets and other raw materials, and finally made paper through processes such as beating, pounding, frying and baking.
But now, in the early Ming Dynasty, papermaking technology has been continuously improved in the process of development.
Su Jing, a paper mill, mainly produces two types of paper.
One is rough paper used to package goods. It is yellowish in color and not very delicate on the surface. It is not suitable for writing, but it is cheap.
The other type is bamboo paper, which has a more complicated process and a much higher cost, so the price is naturally more expensive.
Su Jing still attaches great importance to this papermaking workshop.
Because he has been keenly aware that the market demand for paper will only become stronger.
However, Su Jing is not very satisfied with the current papermaking process.
Because papermaking is a craft, when it is passed down, it is mostly operated by one person from beginning to end.
In other words, a worker needs to follow up on every process from the initial selection of raw materials to the final paper output.
Su Jing has not intervened in production before. This production method is inefficient, but it is still sufficient.
After all, there was only so much market demand at the time. Although this was slow, it was sufficient.
Now Su Jing has the idea of expanding production in her mind.
This model must be changed!
The assembly line is the most efficient production method.
Although in previous lives, assembly line sweatshops were usually considered to be a form of oppression, in the early Ming Dynasty, people undoubtedly liked an assembly line factory that could provide stable jobs.
After all, Su Jing's factory never defaulted on wages.
His credibility is also quite high among the people of Lishui County.
"No, we have to train the entire staff first."
Su Jing looked at the workers at work and muttered to herself.
Employee training was something Su Jing had done a lot in her previous life, and she was quite familiar with it.
Now that she had decided, Su Jing immediately started to implement it.
He immediately found the current person in charge of the paper mill and asked him to tell all workers when he got off work tonight that there would be a seven-day training.
Salary will be paid as usual, and food and accommodation will be included.
But there is one requirement: during these seven days of intensive training, you cannot go anywhere.
When Su Jing said it, the person in charge of the paper mill couldn't believe it.
Is this such a good thing?
For seven days, food and accommodation are included, and you don’t have to work.
He was so frightened that he quickly asked a few more questions, which meant that the speaker, Su Jing, could convince these workers. Otherwise, they would all think they were human traffickers.
Su Jing's good reputation allowed his employee training plan to be carried out smoothly in the first step.
The next days will be quite simple.
Zhu Biao polished the glass all day long. In order to let the soldiers on the front line use useful telescopes as soon as possible, Zhu Biao forgot to eat and sleep.
Su Jing didn't have any secrets, and passed on all her previous polishing and calibration experience to Zhu Biao, as well as a standard convex lens and a standard concave lens.
After teaching these, Su Jing began seven days of special employee training.
For Lai Yong, it was seven days of training, and for Su Jing, it was seven days of training.
Both Zhu Biao and Su Jing focused on their own affairs.
While these two people were concentrating on their work, one person began to feel a little restless.
Forbidden City, inside Fengxian Hall.
Zhu Yuanzhang was pacing back and forth, with doubts almost written on his face.
Forget about his son Zhu Biao. Now he is busy with the telescope every day and has no time to do other things.
But what about Su Jing?
Five days!
It has been five days. I have not stayed at home all day, but have been in a paper factory, working on something.
"Su Jing, what are you doing, kid?"
Zhu Yuanzhang muttered to himself, completely unaware that he was already paying too much attention to Su Jing.
"Your Majesty, the Duke of South Korea wishes to see you."
The eunuch's summons sounded.
"Xuan."
Zhu Yuanzhang immediately returned to his normal appearance.
Soon, Li Shanchang walked in and said respectfully to Zhu Yuanzhang: "Your Majesty, I am here to report."
"oh."
Zhu Yuanzhang said with joy on his face: "Shan Chang, you should be talking about the implementation of the prince's anti-corruption decree."
Li Shanchang immediately said: "Your Majesty, I have been promoting this matter for the past few days, and now it is basically completed. Thanks to your Majesty, everything is going smoothly."
Sure enough, Zhu Yuanzhang was quite satisfied when he heard the news that everything went well.
Li Shanchang continued: "From what I can see, His Highness the Crown Prince's decree has been effective, and the atmosphere in the Ming Dynasty is getting better. His Highness the Crown Prince's move is really a blessing to the Ming Dynasty."
It is better to brag about your own work than to brag about Prince Zhu Biao.
As Zhu Yuanzhang's left prime minister, Li Shanchang knew what he should say.
"Shan Chang, you are right."
Zhu Yuanzhang nodded and said: "The prince is so capable, I can rest assured. You have worked hard during this period."
"Your Majesty's words are serious. I am only following His Highness the Crown Prince's decree. It doesn't mean anything."
Li Shanchang lowered his head and said.
Zhu Yuanzhang looked at Li Shanchang and said with a smile: "Shanchang, you have been with me for a long time. You and I, the monarch and my minister, I won't say any polite words. Just tell me what rewards you want."
"I'm scared. I just did some trivial work and don't deserve your majesty's love."
Li Shanchang immediately knelt down towards Zhu Yuanzhang and said with great respect.
"Such a good person, please get up. You didn't make any mistakes. Why should you kneel down?"
Zhu Yuanzhang had a somewhat reproachful tone, but the expression on his face was quite satisfied.
"Thank you, Your Majesty."
Li Shanchang stood up and said to Zhu Yuanzhang: "Your Majesty, the young minister of Taichang Temple is very cooperative this time when I implement the administrative order, which makes my work a lot easier."
"Oh, you mean Hu Weiyong?"
Zhu Yuanzhang recalled for a moment and asked.
Li Shanchang nodded and said: "Exactly, as a young minister of Taichang Temple, he has little to do with this anti-corruption matter, but he is very serious. I am deeply impressed, so I mentioned this."
"Um."
Zhu Yuanzhang nodded and said, "I understand."
"By the way, next year's Northern Expedition and the rear army's food and grass matters need to be done more carefully."
Li Shanchang immediately bowed and cupped his hands and said: "Your Majesty, don't worry, I will definitely do my best to ensure the food and grass for the soldiers."
Although Li Shanchang could figure out Zhu Yuanzhang's thoughts, there was absolutely no doubt about his own ability.
"Okay, Shanchang, you are really my Xiao He!"
Zhu Yuanzhang patted Li Shanchang on the shoulder very happily and said.
Li Shanchang also immediately expressed: "Thanks to His Majesty's love, Shanchang will definitely live up to His Majesty's trust."
After reporting the matter, Li Shanchang left Fengxian Hall.
Zhu Yuanzhang was in a good mood, and he didn't care so much when he thought about the fact that there was no news about Zhu Biao and Su Jing for five days.
"By the way, how is Lao Wu doing now?"
Zhu Yuanzhang slapped his head and suddenly thought of his fifth son, Zhu Rui. The Agricultural College had also been established, and research on crops was already underway.
Lao Wu, who had vowed to take the initiative to study, what is the situation now?
Zhu Yuanzhang suddenly became interested.
"Speaking of which, I haven't visited the Agricultural College yet, so I just want to go check it out."
Zhu Yuanzhang muttered to himself and set off directly to the Agricultural College.
In a field outside Yingtian Mansion, this is the experimental field of the Agricultural College.
Yang Siyi, the Secretary of the Ministry of Household Affairs, was following the fifth prince Zhu Ju. He was very careful and did not dare to be careless in the slightest.
This is the fifth prince. If anything happens to him, he, the Minister of the Ministry of Finance, may not have enough brains.
At first, he was quite surprised when he knew that the fifth prince Zhu Xi was coming.
I thought Zhu Rui was just curious and came over to have a look, but he didn't take it seriously.
After all, Zhu Rui is nine years old now, just an innocent child.
But after Zhu Ru arrived, Yang Siyi found that things were a little different from what he imagined.
Although Zhu Rui is young, he is not here to play around. He really wants to study seriously. He does everything by himself, and he is not tired or dirty at all.
Therefore, although Yang Siyi was following Zhu Ru and watching carefully, he was not impatient at all.
Now that the season has just entered autumn, it is also the time for wheat sowing. Zhu Ju is observing the condition of the land in the experimental field.
"Mr. Yang, before planting this wheat, the land needs to be plowed. How is the depth determined?"
Zhu Ru asked Yang Siyi.
"Back to the fifth prince, it is mainly determined based on the depth of rooting of the wheat after it grows."
Yang Siyi answered immediately without hesitation. He was once a minister of agriculture, not an airborne minister of household affairs.
He continued: "Of course, in order to more accurately study the relationship between wheat yield and land plowing depth, we also tried to increase the plowing depth by a few points in another experimental field."
What Yang Siyi was talking about was the controlled experimental method, which was what Zhu Biao guided and what Su Jing taught.
Even though it was just a simple method, in Yang Siyi's eyes, it was quite shocking.
This was a line of thinking that he had never thought of before.
With the guidance of this methodology, he is quite confident that the Agricultural College can produce results.
Zhu Rui listened to Yang Siyi's answer, nodded silently, and then continued to observe in the field, asking questions from time to time, why Yang Siyi was always there when called, and answered whatever he asked.
Not far away, Zhu Yuanzhang, who had been here for a while, looked at this scene and was quite pleased.
This Lao Wu is indeed not just talking about it for fun, he is really interested in this aspect.
In this case, maybe he should consider how to let Su Jing teach Zhu Ru now.
