The glass workshop, which is still under construction, is full of craftsmen working everywhere you see, and a color official is standing on a high ground, introducing the planning of the entire glass workshop to Li Jie, but Zhu Yunxi, who came with Li Jie, is not here.

"Li Banyu, please see, this is the most important production area, and the firing of glass will be mainly completed here in the future, and in our plan, three workshops will be built here, and the glass produced will be enough to supply the application of the imperial court!" The official pointed to the busy construction site in front of him.

This middle-aged color official is named Ma Hasha, he is also Ma Hama's third brother, they also have an elder brother named Ma Sha Yihei, when the three brothers accompanied their father Ma Druddin, from Constantinople, the capital of the Eastern Roman Empire, came to the Central Plains, with their own talent and learning to be reused by Zhu Yuanzhang, became a rare color official in the court.

Speaking of Madruddin this person, it can be said that it is quite remarkable, his achievements in astronomy are extremely high, and he is extremely accurate in observing astronomy, so he is called "Mr. Da Measure", originally he did not have the surname Ma, but he followed the local customs, and simply took Ma as his surname, so his children and grandchildren are also surnamed Ma.

"Very good, but is the production of these three workshops only enough to supply the clairvoyant workshop?" Li Jie looked at the well-organized construction site and nodded first, and then asked again.

"Yes, we asked the claireye workshop about their needs, and then built the workshop according to their needs, so as not to waste." Mahasa immediately replied that compared to his brother Mahama, Mahasha's astronomical attainments are average, but he knows a lot of miscellaneous studies, and this time he recruited color craftsmen to build a glass workshop, and Zhu Biao also asked him to be in charge here.

"No, it's too little, the glass workshop can't just supply the clairmind workshop, glass can not only be used for military use, but also for civilian use, so the output must also be more than doubled, and even increase in the future!" Li Jie shook his head and said.

Although he was not the official in charge of the glass workshop, the workshop was built on his suggestion, so he also had a lot of say in the area.

"Actually, I've also thought about civilian use, but we are here mainly to solve the shortage of glass raw materials for clairvoyance, will the court agree to let our glass be sold?" Hearing this, Mahasa hesitated and said that the imperial court has never advocated competing with the people, so he did not dare to consider the civilian side.

"Don't worry, I will explain this matter to the prince, you just have to build, and you must leave enough land for future expansion, so as not to be insufficient in the future!" Li Jie was resolute.

Li Jie insisted on glass for civilian use, not only for his own glass mirror, but also for the wide range of uses of glass, such as windows, all kinds of glassware, and even glass to make greenhouses, in winter to achieve vegetable freedom, it can be said that a glass appear, can increase a lot of industries, each industry can feed a lot of people.

Seeing Li Jie carrying this matter, of course Mahasa would not refuse, and then he took Li Jie around other places, although many places are still construction sites, but some rudiments can already be seen.

After visiting the entire glass workshop, Li Jie and Ma Hasha said goodbye, after all, the other party was in charge of the entire workshop, and there were many things to be busy, he did not come here to supervise the work, the main goal was to train Zhu Yunxi.

Li Jie stepped to the front of the workshop, which was the first part of the construction, and many places have already been built, for example, when Li Jie came here, he smelled a smell of food, because the canteen of the workshop was here, and now it was dark, and the canteen was also preparing food.

On the east side of the cafeteria, there was a small room, Li Jie pushed the door and walked into the room, only to see Zhu Yunxi holding his head in his hands, sitting behind the table with a sluggish face, and the hair on his head was scratched messily by him.

"How is Your Highness's calculation, can you understand the purchase and consumption of the kitchen today?" Li Jie stepped forward with a smile and asked, the first thing he arranged for Zhu Yunxi was very easy, that is, settling accounts, after all, as the emperor's grandson, if he couldn't even calculate the accounts, what else could he do in the future?

"I didn't ...... No! Zhu Yunxi's face was flushed and he lowered his head, as if he was embarrassed to look at Li Jie.

When Li Jie arranged the task of settling accounts for him just now, he still felt that he was a big talent and a little use, after all, he had also studied arithmetic before, but when he really took over, he found that a small back kitchen, the ingredients and items that come in and out every day, plus the wages of the personnel, etc., are simply a mess, and he scratched his head and didn't figure out a clue.

Li Jie was not surprised at all by Zhu Yunxi's answer, only to see him walk up to Zhu Yunxi, and then picked up the booklet in front of him and looked at it, all of which were Zhu Yunxi's calculus, but all the arithmetic in this period was recorded in writing, and this article had nothing to do with the previous article, which also led to the whole record being very confusing, no wonder Zhu Yunxi didn't understand.

"That's not how the accounts are calculated!" Li Jie looked at the account book for a while, and said to Zhu Yunxi again in a serious tone.

"Li Ban read, this kind of thing, just find a bookkeeper to do it, as the so-called 'those who work hard govern people, and those who work hard govern people', as a superior person, as long as you know people and make good use of them, you don't need to bow down at all!" Zhu Yunxi suddenly raised his head at this time and said a little unconvinced, children of his age have strong self-esteem, and of course they are unwilling to admit their failures.

"Hehe, it's a set of reasons for yourself!" Li Jie laughed dumbly after hearing this, and then asked again, "Of course it's easy to find someone else to settle the account, but have you thought about it, if this person is unreliable and does things in the accounts, such as deducting the food of the craftsman to make a profit, or shoddy, you can't understand the accounts, wouldn't people cheat you how they want?" ”

"I ......" Zhu Yunxi was still not convinced, and wanted to say that he would find someone who knew the accounts to supervise, but after thinking about it carefully, if the supervisor and the person who settled the accounts colluded with each other, he would still be able to keep him in the dark at that time, which made him immediately like a deflated ball, and the whole person also withered all of a sudden, he didn't expect to be hit so the first day he left the palace.

Seeing that Zhu Yunxi didn't speak, Li Jie didn't make fun of him anymore, but sat down next to Zhu Yunxi, then picked up a pen and paper and said: "Come, I'll teach you to settle accounts, if you can't even calculate the accounts of a back kitchen, how will you manage it in the future...... cough~, help Your Majesty and the crown prince govern the country? ”

Hearing that Li Jie was going to teach himself to settle accounts, Zhu Yunxi finally got up and sat up straight, Li Jie first helped him sort out the accounts, and then used the most traditional method to sort out the accounts, and finally calculated the daily entry and exit values.

"Huh? Why did this messy account become so simple when it came to Li Banyu's hands? Zhu Yunxi looked at Li Jie's accounts of the ban, and his face was both surprised and puzzled.

"It's not that it's easy to get into my hands, but you have to learn too many things, and the method I'm using now is actually the most troublesome, and then I'll teach you a simpler and more understandable way, as long as you learn it, not to mention a small kitchen, even the entry and exit of the treasury can be calculated by you!" Li Jie spoke again.

"Count the treasury? Really? Zhu Yunxi's eyes widened in disbelief when he heard this, the back kitchen of a workshop has already made him scratch his head, and the entry and exit of the treasury is more than ten thousand times more complicated than the back kitchen, I heard that the household department is to gather hundreds of scribes to settle accounts together, and it still needs to be counted for ten days and a half months, if one person goes to calculate, it will be counted to the year of the monkey and the month of the horse?

"Don't believe me? Do you want us to make another bet? Li Jie suddenly smiled slyly.

"Bet on it! Or what about the last bet? Zhu Yunxi obviously did not learn the lesson of last time, and took the initiative to make a bet.

"Okay, that's it, I'll teach you a new algorithm, and then you can wait to admit defeat!" Li Jie smiled confidently.

The ancients' level of mathematics is relatively low, and the application of accounts is also very low-level, which he has long seen in the accounts of the Ordnance Bureau, although the entry and exit of the treasury is larger, but as long as the statements of later generations are used, it is not difficult to take some time to calculate the accounts, so Zhu Yunxi lost again, but this time let him do something?
