Married to Lao Liu Tou, such a long-winded goods, and obeyed Zhao Guogong's orders, followed Lao Liu Tou in the countryside on the outskirts of the capital to serve Wu and Zhang Shou's mother and son, lived for so many years, Aunt Liu thought that her life was to look at the unchanged scenery in the fields, and then slowly grow old, she never dreamed that in this life in addition to returning to the capital, she would be so beautiful!

Even if there is no young and beautiful young man among the cooks who are so diligent that they are afraid that she will be impatient, the meaning of holding her is the same. And the dishes she made in her hand, after these people tasted them, they either exclaimed, or sighed, or praised, or shouted, in short, each one was more and more excited.

At that moment, when Zhang Yuan even often had to compete with Mrs. Xu for the power of the kitchen - although one was outside the pipe and the other was in the pipe, Aunt Liu had a kind of drunkenness as a chef at this time, where could you still see the old Liu Tou in the corner with a tangled face and a wary face? That old man, who is old and wrinkled and can't please himself, deserves to let him be anxious there!

Among the chefs, because they have been selected for the imperial dining room, Chef Fang, who has been starred in the moon, tasted the dishes one by one at this time, and his amazement was stronger than anyone else. In his opinion, Aunt Liu's cooking skills can barely reach the middle and upper level, and she is still far from the top, but the problem is that he has never heard of them, let alone the ingredients he eats, but he is quite proficient.

So, after finally eating the crispy sour and spicy shredded potatoes, he was finally moved, and then looked at the chefs behind him, some of them had been so spicy that they stuck out their tongues and spat out desperately, and he couldn't help but give Aunt Liu a thumbs up.

"If it weren't for Dr. Zhang's discernment, we wouldn't have known that there were such good ingredients in the world; If it weren't for Mrs. Liu's good cooking skills, we wouldn't know how to do these things! With your demonstration, although you can't say that you are very numerous, at least you will not be blinded and you can complete Dr. Zhang's extra question. ”

Aunt Liu was so complimented by Chef Fang that her eyes narrowed, and her mouth was even more smiling. On the other side is the future imperial chef, but I didn't expect the future imperial chef to praise her skills...... With such a vision, it's no wonder that the emperor would choose someone to be the imperial chef!

"Chef Fang, you have won the award, my two hands are ordinary, where can I compare to the chefs who have been on the stove for many years and have superb cooking skills?" The sedan chair was carried by everyone, even if she was proud, Aunt Liu was not so forgetful, and she flattered everyone with a smile. Seeing that even the person who showed a bitter face at the beginning finally looked better at this time, she reminded her two more mysteriously.

"I don't know about the people who judge upstairs, but my young master's mouth is top picky, you have to show your real skills. Although it is impossible for him alone to overshadow other judgments, if he says it badly, others don't say it, and the eldest lady will definitely not say it well. ”

Aunt Liu taught a plausible experience, and when she saw that everyone nodded again and again, she didn't look at the old Liu Tou, who was desperately glancing at herself, gesturing, and even jumping to wipe her neck, and said with a smile: "So, I'll tell you a trick." The young master loves spicy, no spicy or unhappy, just this dish made of chili peppers, if the young master does a good job, he can eat one more bowl of rice at a time......"

Hearing that Aunt Liu was teaching a large number of chefs there, and those people nodded there again and again as if they had received a treasure, Old Liu Tou only felt that the green tendons on his forehead were bursting out, and he wanted to knock him unconscious and drag people back.

Why didn't he know that his mother-in-law was so good at fooling people?

With that said, wouldn't all of those chefs desperately want to make a dish seasoned with chili peppers on this extra game? Is that dish that easy to make?

Even if his mother-in-law was taught by her own young master, it took a lot of effort to master the key to seasoning!

In order to prevent Aunt Liu from being too tricky, Lao Liu Tou finally had to cough heavily, and then said: "All chefs just need to play steadily, don't accommodate for the sake of my young master's taste." For example, a master who is good at Huaiyang cuisine and Subang cuisine, instead of racking his brains to make chili peppers, it is better to think about how to make light foods such as potatoes and pumpkin delicious. ”

Seeing Aunt Liu glaring at him in annoyance, he didn't have the anger to look back at him, so he said sincerely: "Because the capital has just been sown, it is impossible to grow it in a short time, and now these ready-made ingredients are brought from Cangzhou, which is extremely limited, and each master can only choose one, but this one, you can first take a part of the water and boil it to taste." ”

"My young master said that boiling can bring out the original taste of food, and then you can figure out how to make it."

Although all the chefs present were older than Zhang Shou, such a sentence relayed by Lao Liu Tou still attracted a chorus of approval - compared with before, many people feel that Zhang Shou is indeed worthy of his self-proclaimed foodie name.

Because boiling can indeed bring out the most original taste of a food!

Finding that his suggestion was obviously accepted, Lao Liu Tou smiled and said: "Of course, only one kind of ingredients such as pumpkin, potatoes, and peanuts can be selected, but chili peppers and tomato sauce are not counted, this is a condiment, so everyone will get a rough plate of oil chili peppers and a plate of tomato sauce, but there is only one, but you can save a little, these are very expensive." ”

Aunt Liu finally saw the hole, and hurriedly said: "That's right, there are very few chili peppers now, so they are more expensive than those Nanyang spices." An ordinary vendor pushing a cart selling rice noodles at the canal wharf in Cangzhou has been doing more than two times better than before since adding chili peppers to it. There are even those who are spicy as life, just such a small dish, willing to pay consistent money! ”

Mother-in-law, you don't feel uncomfortable if you don't fool today, right?

Old Liu Tou was almost angry with Aunt Liu's mouth that was more powerful than himself today, so he hurriedly stepped forward and pulled someone up and went outside: "Okay, okay, the lady in the family is also preparing for the young master's birthday, you should go back to Zhang Yuan to prepare!" If you don't speak, no one will treat you as a dumb person, go quickly! ”

Although Lao Liu Tou quickly coaxed Aunt Liu away, Aunt Liu's dishes just now really left a deep impression on everyone - especially the dishes with rich sauce such as Gong Bang Chicken and Babao Hot Sauce, which made many chefs feel that they had touched Zhang Shou's spleen and stomach.

Of course, there are also many people who think that Lao Liu Tou is reasonable, and he should not completely follow Zhang Shou's taste as the criterion - after all, this is not Zhang Shou choosing a chef alone, so many judgments are placed there, and you can't be too curious in order to please someone.

So, after a large group of people thought carefully and carefully, they began to choose the ingredients they wanted to use.

However, when the two people who were in charge of reviewing the distribution and registering it with Xiao Peanut and Xiao Cheng, Lao Liu Tou still found that although the other ingredients of the chefs had their own preferences, only chili peppers were ...... That's everyone took a dish!

Tomato sauce is not that hot!

Zhang Shou didn't know about the little stories that happened below. As the birthday star of today's birthday, although Zhang Chuan, the Duke of Qin Guo, and Zhang Kang, the Bo of Weinan, joked that he would let him sit with Zhu Ying and Princess Yongping in the chief, but where was he willing. Even if he doesn't care about this kind of avoidance of different tables for men and women, he can sit at the same table with Zhu Ying, and he is not familiar with Princess Yongping!

So, under his insistence, Zhu Jing called Zhu Ying over and asked her to accompany Princess Yongping, who was sitting alone at a table, and finally arranged all the seats.

There is no doubt that Zhang Shoude accompanied Ge Yong and Chu Ying Qi Jingshan, the three grandfather-level teachers, while Zhu Jing and Zhang Chuan and Zhang Kang were at the same table, Zhu Ying reluctantly accompanied Princess Yongping, and the three big and one small four monks and the old salted fish also shared a table, and only four tables near the window were opened in the huge place. A few of the little eunuchs who came out of the palace with Princess Yongping were the little guys who served the dishes, and Chu Kuan personally stood behind Princess Yongping to serve.

In this regard, Princess Yongping felt very uncomfortable - she didn't understand, today was not the Yuehualou Wenhui, if her father wanted to know the situation, he just sent an inner servant to come out with her, why did he let Chu Kuan, the first person in the inner court, follow. However, when she saw that no one was munching next to Zhu Ying, she suddenly felt that she was too sensitive, far inferior to Zhu Ying, who had no heart and lungs.

Sure enough, she stared at Zhu Ying for a while, and Zhu Ying raised her head and asked inexplicably, "What do you think I'm doing?" Could it be that I got it in my face? ”

Seeing that the three nobles who had served Ruizong were talking and laughing-although Zhang Chuan was younger, he didn't seem to be the same generation as Zhu Jing and Zhang Kang, but he grew up during the reign of Emperor Ruizong-and Ge Yong and the three of them were carrying Zhang Shou as if they were discussing some arithmetic problem, Princess Yongping couldn't help but snort softly at Zhu Ying: "You have always been the same, and you will never have a sense of crisis!" ”

"In the past, I had my grandmother, my father and my eldest brother, and in the future, I had Ah Shou and Aunt Wu, and the emperor and the queen mother would also take care of me, why should I have a sense of crisis? As far as your character is concerned, if you say it well, it is delicate and thoughtful, and if you don't say it well, you are too idle and thinking about it! ”

Without waiting for Princess Yongping to get angry, Zhu Ying smiled evilly: "You know, it's easy to get old if you think too much!" ”

Princess Yongping was suddenly sarcastically raised her eyebrows, but at this time, she heard a bang on the side, and when she turned her head to look, she saw that Ge Yong had already stood up. She also thought that the old lady and Zhang Shou, a closed disciple, were unhappy because of something and slapped the table, but when she looked closely, she saw that the old lady slapped two thin booklets on the table.

"The "Auditing Tips" and "Longmen Account Tips" that your kid wanted, these were written by me and Old Man Chu and Old Man Qi with all our brains. So now, shouldn't you explain what is going on with the exam questions you came out of the second phase of the Jiuzhangtang this time? Why is the last question so weird? ”

Ge Yong didn't notice what the other two tables were looking at him, and he only cared about himself at this time.

"In the volume of analytic geometry you gave me in Cangzhou, the plane Cartesian coordinate system in it, I and the two old men almost figured it out, but this time you drew a coordinate system and a functional curve on that problem, and then said that you were looking for the area of a specific interval. I've been calculating this thing for a long time, Old Man Chu and Old Man Qi, do you expect those little guys who haven't been systematically exposed to arithmetic to make it? ”

Zhang Shou had to stand up and press his teacher on the chair and sit down, then he smiled apologetically at Princess Yongping and Zhu Ying, who were concerned about this, and then said hello to Zhu Jing and the three apologetically, and then returned to his seat, and then said in a low voice: "Teacher, don't you think it's a shame to discuss this kind of academic issue at this time?" ”

"Anyway, the three of us ate three meals with you last time, so it doesn't matter if you don't eat this time! You kid don't do your job all day long, and you still want to diverge from the past today? There are no doors! If you don't make it clear, you won't have your birthday today! ”

Seeing Ge Yong's puffed up look, Chu Ying and Qi Jingshan were all watching the excitement on the side, Zhang Shou knew at a glance that the teacher had probably endured it for a long time. So, he could only move the plate in front of him to the side, then poured some tea on the corner of the table, and then dipped the tea and drew an x-axis and y-axis on the table, drawing a curve through the origin.

"There is a function f(x)=x^3, and on the defined domain (1,6), the graph enclosed between the image of the function and this abscissa is solved, and its area is solved...... I remember that this is how I came up with the last question on the entrance exam. The teacher said that the calculation took a long time, so it should be the exhaustion method, in fact, this is the same as our usual method of solving the radial ratio......"

"Of course, the exhaustion method is actually difficult for ordinary people, so I also noted on the question, I only hope that students will come up with ideas, and there is no need for a clear answer. There is a very convenient, but very brain-twisting solution to this problem......"

Ah Liu, who was carrying a teapot upstairs on the side, heard this series of words, and immediately tiptoed directly to Zhu Ying's table. At this time, it's better for him to stay away! Sure enough, he saw that Zhu Ying, who was eavesdropping, was also rubbing her eyebrows in pain, and even Princess Yongping, who has always been called a talented woman, had a somewhat dull look.

Zhang Shou said and thought at the same time, trying to explain it in simple sentences. After all, when he first started to learn advanced mathematics, it cost him a lot of money just to accept something like calculus, which is completely different from middle and high school mathematics...... Well, it was probably a week during the summer vacation, and I completely accepted this line of thinking. So he's by no means a genius.

"In the definition domain (1,6), divide the curve f(x)=x^3 into n parts, and each part is spaced △x, and then make vertical lines on the vertical x-axis, intersect with the curve, and then connect these vertical lines one by one to obtain a series of rectangles. As n is larger, the sum of the areas of these rectangles tends to be the area of the graph enclosed by the curves f(x) and x-axis in the domain (1,6). ”

"And if n tends to infinity, and these rectangles will wirelessly approach a straight line, then, can we understand that the sum of the areas of the rectangle that tends to an infinite number of straight lines is the area of this figure?"

When he was expounding geometry, the reason why Zhang Shou used the term rectangle instead of rectangle was because it was easy to understand...... Anyway, after it was easy to finish a "simple" idea, he saw that the faces of the three arithmetic masters in front of him were all green.

He was not surprised at all by the expressions of the three elders who could be called the grandmasters of arithmetic in these years, and he really couldn't help it, it was okay to roughly compile a mathematics textbook for elementary school, junior high and high school, and a textbook for systematically explaining calculus, he had to prove the fundamental theorem of calculus first, right? To be honest, he already feels that his memory is extraordinary, but this kind of system still fools these three bigwigs into building it with himself!
