The rise of the prince

Chapter 139 Qiu'er's Status

"My lord, what are we going to do?" Yue'er was puzzled, carrying two small baskets, bouncing after Li Ye, Li Ye was carrying a hoe, and Wei Yubai was also carrying a shovel.

Chinese New Year was almost here, the weather began to clear up, and the temperature began to rise. The cold chill was no longer aggressive, and he couldn't wait to take off his heavy coat. Although it was still a little cold, he could bear it.

Li Ye laughed, and said teasingly, "Today we will go to cauliflower."

"Is it the cauliflower thief's cauliflower in "Swordsman"?" Yue'er giggled, bouncing around like a flying butterfly.

As soon as Li Ye was surprised, the little girl learned to tease him: "If you want to pick it, you should pick your little lily first."

Wei Yubai has never heard of Xiaoao Jianghu, so he doesn't know what the flower picker means, but Yue'er blushes suddenly, and runs away a few steps: "Didn't your son say that I am still young, you see, sister Wei is already in full bloom." so pretty"

"What are you talking about?" Wei Yubai asked in confusion.

Li Ye shook his head: "To discuss a philosophical issue, let's go for a walk and pick flowers first." He fooled around.

Qiu'er wanted to come too, but she was too busy.

Qiu'er's status in the mansion is gradually reflected. In the past, it was only Yan Lu who asked her to settle the accounts. Now all the blacksmiths and carpenters in the family, Yan Kun from Tingyulou, and Gu Feng from the wine cellar, all come to ask for advice.

After all, as long as it involves engineering, there will be a lot of calculations, and in this era, no one can even calculate pi accurately. Many things can only rely on experience and trial, which will cost a lot of useless work and money.

But with Qiu'er, those unnecessary attempts and estimates can be saved, because mathematical calculations never go wrong.

If you want to cast a pot, please report the size of the stove mouth, how deep the pot should be cast, and Qiu’er can tell the blacksmith what the diameter of the pot should be; for making a wine cage, just say how many catties of grain it can hold, and the size of the bottom pot, Qiu’er You can tell them how long the wood is, how long the opening is, and what the diameter is; to lay the foundation, just tell them the size of the hole, and Qiu'er can tell them the approximate amount of asphalt and gravel.

The most amazing thing is a small meeting in the palace.

From more than a month, Li Ye would call together all the important people in the palace every ten days or so, including Yan Kun who managed the Tingyu Building; Ji Chunsheng, the head of the guard who was in charge of the security system of the palace; The general manager of the palace, Yan Yan; the cook in charge of the kitchen in the palace; the seal in charge of the wine cellar;

This approach is more out of psychological considerations. It can make people in the Wangfu group more familiar, which is conducive to enhancing the cohesion of the group and creating a sense of collective honor.

Li Ye would bring Qiu'er to listen every time, except for Yan Yan, the others didn't understand. After all, this is a major matter in the palace. He said cryptically.

As a result, Yan Kun raised a question at the small meeting at the end of the year a few days ago. He found that the pork dishes in the restaurant, such as braised pork, steamed pork with noodles, and pickled pork with preserved vegetables, could be sold more as long as the price was reduced. , also came.

Selling more is a good thing, which means earning more, but selling more will also lower the price, and the less money is not a small amount after each plate is reduced.

He tried several times. Sometimes he made more money than before, and sometimes he lost more money than before. If the reduction was less, he would not sell much, and if the price was more reduction, the unit price would be lower again. So he was in a dilemma and couldn’t make up his mind for a while. Everyone was confused. , The last idea he came up with was to let him try more, and he would know what price was right after trying it for a year or so.

Li Ye immediately understood what was going on, and asked him specifically how much he had reduced, how much he had sold, the price of wholesale pork, and the original price of each dish. Then he looked at Qiu'er, and Qiu'er understood. Wen Wen nodded, then Wen Wen quietly calculated in his mind for a while, and immediately told him how much he should drop to make Ting Yu Lou earn the most.

Everyone looked at her who suddenly interrupted, with disbelief in their eyes. Li Yeli overcame all opinions and asked Yan Kun to do what Qiuer said. As a result, the next few days after listening to Yulou, it was indeed more profitable than before, and the daily profit was almost 200% higher. More than enough!In a month, there will be about [-] taels of silver!

Yan Kun was completely stunned, and hurriedly brought a gift to the palace to thank Qiu'er, and said that adults don't remember villains' faults and so on.
This matter also spread rapidly in the palace, and the more it spread, the more magical it was, and the senior officials of the palace began to admire and respect the quiet little girl who always stood behind the prince. So it is simply to calculate the good and bad, and the half-celestial being who breaks the geomantic omen, this can be accurate!From then on, everyone respected and feared her.

In fact, Li Ye already realized when he first heard what Yan Kun said. This is a common profit maximization problem. A quadratic equation in one variable can be solved. The image of the equation is a parabola, and the opening of this problem must be downward. Find a maximum solution that maximizes the benefit.

Qiu'er understood it as soon as she heard it, so Li Ye was relieved to let her speak.

Others don't understand this truth, and they can't explain it clearly. They will only be regarded as metaphysical things such as fortune tellers and semi-immortal fortune-telling. But he and Qiu'er both understand in their hearts that mathematics changes the world, and knowledge changes destiny.

After going through so many things, Qiu'er has a high prestige in the palace. Many times, everyone will come to ask her for advice if there is something difficult to decide. Forget about Yan Kun, Yan Yan and those craftsmen, even Gufeng who needs to ferment food. Ask Qiu'er to count the days for him.
Li Ye's face turned black at that time, and he really regarded his precious Qiu'er as a fortune teller!The old man was kicked out at that time.

Mathematics is very likely to be the common language of the universe, and many problems can be solved.

Li Ye brought Yue'er and Wei Yubai to the back mountain of the Wangfu. This barren hill is very large and still belongs to the territory of Xiaowangfu but has not been opened. Xiaowang is a martial artist, and he liked to use it for horse racing when he was alive.

After the death of King Xiao, it was useless. The barren hills were full of wintersweet, white and yellow, and a small basket of wintersweet was picked in the plum garden, all of which were yellow.Most of them were picked by him and Wei Yubai. Yue'er was like a cheerful bird, shuttling among the flowers and forests. She was finally so happy. Li Ye just watched with satisfaction and didn't bother him. The little girl would come back when she was tired.

Then he carried another basket and Wei Yubai dug a basket of soil outside the stable.

Neither Yue'er nor Wei Yubai understood what he wanted to do, he was picking flowers and digging soil.

"My lord, the flowers are so fragrant that you can pick them back to make plum cakes, but what are you doing digging? You have to dig beside this dirty and smelly stable." Yue'er tilted her head and asked.
