Lao Tzu is a toad

Chapter 19 Erhu Man

Mu Hongli first dragged Zhao Jiadi to search for books in the school bookstore. She thought she would be able to find something out of the sidelines when picking books, but Zhao Jiadi died down after his amazing performance in class, and resumed the unknown role-playing In fact, this is not because Zhao Jiadi intentionally hides his strength in front of Mu Hongli, but in terms of the breadth of his reading, he is no match for Mu Hongli, who was born in a scholarly family. As a literati with a lot of knowledge, he only chooses the interesting research, and he goes in like a dead end and never comes out. Throwing him two thread-bound and yellowing ancient books, one "Compendium of Materia Medica" and one "Qing Nang Jing", Zhao Jiadi couldn't get out after he got stuck in it. Numerology and the three veins are all very particular about calculation and derivation. Grandpa Zhao Jiadi claimed that he met an expert when he was young. , but the headache is that Zhao Jiadi's grandfather threw him a copy of "Acupoint Punishment" or "Looking for the Dragon" when he had nothing to do. At that time, Zhao Jiadi was only a little kid, but he still enjoyed it It is also fortunate to have such a grandfather who "pulls the seedlings to encourage growth", otherwise Zhao Jiadi's brain would not be so brilliant in science when he grows up, so in some fields that Zhao Jiadi is familiar with and good at, his self-confidence is almost conceited, but Mu Hongli Talking to him about classical music or poetry and literature is a bit of a joke, and Zhao Jiadi is kind, he never plays tricks on things he doesn't understand, and just shut up, so Mu Hongli didn't give any advice when picking books. Finally, when the cafeteria opened, Mu Hongli originally wanted to invite him to eat in a special private room, but Zhao Jiadi didn't agree, so he ordered a lunch worth 9 yuan. He didn't have any wine, so he compensated with two meat dishes. You’re welcome, Mu Hongli’s diet is light, and with her menstrual holiday, she doesn’t dare to eat indiscriminately. Zhao Jia asked for 5 meals in one breath, while Mu Hongli only wanted one or two. The two formed a stark contrast. After sitting down, Zhao Jia Jiadi started to deal with the same rice as Xiaoshan. Mu Hongli saw a lot of roosters, ducks, and peacocks who tried their best to show their gorgeous side in front of her. Zhao Jiadi was too different. It would not be too rough to gobble it up, so Mu Hongli, who was sitting opposite Zhao Jiadi, smiled and said, "I don't know how to persist a little longer, so as to leave a good impression?"

"They are all people who want to live together for the rest of their lives. If you have shortcomings, you should expose them early, so as not to be like some couples lying on the same bed and suddenly realize that they are not familiar with each other." Zhao Jiadi smiled. There is actually no amount of exercise today. Mu Hongli weighs It is estimated that it is only a little over 90 catties. Even if you carry her around in foreign languages, Zhao Jiadi will not be so hungry that he wants to eat half a catty of rice, but he will be aroused to miss Wang Banjin. It was Wang Banjin's proposal to eat half a catty of rice, and he had to hang himself with Zhao Baliang.

"lifetime?"

Mu Hongli smiled, and stared at Zhao Jiadi hard, "The last time we met, you just said to give me happiness, Zhao Jiadi, can you stop being so unreasonable?"

"I didn't go too far with my sword, that's what I really mean." Zhao Jiadi laughed.

"Didn't I tell you earlier that I wrote "The Child" for my boyfriend?" Mu Hongli couldn't laugh or cry.

"Married and divorced, what does it mean to be in a relationship." Zhao Jiadi smiled, with a careless and foolish look.

"The spirit is commendable, but you are doing useless work." Mu Hongli looked helpless.

"The junior high school physics textbook clearly defines the work that has no practical value and has to be done, which is called extra work, and the extra work is the so-called useless work. It can be seen that useless work is a necessary condition for useful work. After all, I am still doing useful work. Work hard." Zhao Jiadi said with a smile, after eating the 3 taels of rice, he ate the remaining 2 taels of rice slowly, as if he had exhausted his efforts, but in fact this is also his habit, he is used to doing things At the beginning, the momentum is overwhelming, and then enjoy it slowly like a cat playing with a mouse. Isn't it the sinister reason to get along with Mu Hongli.

"Sophistry." Mu Hongli laughed as she fell into the trap bit by bit.

"I was the representative of the physics class in junior high school, and I was also the representative of the chemistry class. Is it awesome?" Zhao Jiadi half-truthfully said, now he is the only person in this school who can observe Mu Hongli's pretty face face to face Brutal.

"Niuuuuuuuuuuuuuuuuuuuuuuuuu." Mu Hongli smiled and didn't think too deeply about it, because her younger brother had the best idea of ​​what grades to get into college, and barely squeezed into the last bus of the second line, so in her impression, Zhao Jiadi's grades were not too bad Tough, she has no prejudice against this, and it is even this kind of "weakness" that sets off Zhao Jiadi's surprisingly strong in the field of Russian.So I really don't know how surprised Mu Hongli will be when he knows the truth that the guy in front of him can recite every detail definition of physicalization.

"Tell me about my rival in love, so I can study and formulate tactics and strategies." Zhao Jiadi blinked.

"A little taller than you, a little more handsome than you, a little better in grades than you, that's all." Mu Hongli also blinked.

"I can't get taller anymore. My face is determined at birth. As for my grades, I have also worked hard. It seems that there is no hope of defeating that rival in love." Zhao Jia said seriously for the first time.

"You speak Russian better than him." Mu Hongli smiled, she liked Zhao Jiadi's "frankness and honesty" from the bottom of her heart.

"Russian is good, but it can't be eaten as soft food." Zhao Jiadi smiled wryly.

Mu Hongli glared at him.

"It may not be possible to come to foreign languages ​​often in the future." Zhao Jiadi regretted.

Mu Hongli remained silent on this topic.

"It takes about three days to pull it out once." Zhao Jiadi threw a big mine, which almost made Mu Hongli collapse. She put down her chopsticks and said helplessly: "Zhao Jiadi, we can be friends, it's definitely not that kind of perfunctory Friends of nature, isn't this bad?"

"It's good, but not the best." Zhao Jiadi also managed to get rid of the best rice.

"One-sided guy!" Mu Hongli said bitterly, but it had no lethality, it just added charm.

----------

When Mu Hongli went to the Russian oral training class this afternoon, she had some books that had nothing to do with Russian. Someone asked her to buy mathematics textbooks from Fudan Jiaotong University and other universities majoring in mathematics, such as discrete mathematics and mathematical physics equations. Yes, there are a total of five or six books. After entering the classroom, she fought with man and nature, and finally chose to sit next to that guy. This was the first time since she was in college that she didn't sit in the first row. It didn’t take long for the lunatics who started gnawing at spatial analysis and complex variable functions to be of course only Zhao Jiadi, and the eighth brothers took the books that Mu Hongli helped him find. There were still seven or eight minutes before class, and they started to flip through a copy of "Abstract Algebra" "Basics", Mu Hongli saw a notebook in the corner of the table, the kind that can be bought for two or three yuan, she took it, and her scalp tingled as soon as she opened it, densely packed with formulas and data, mathematics is a high school Mu Hongli, who had a short career, was dumbfounded, and didn't understand even a small piece of information. Zhao Jiadi's handwriting was beautiful, running script, and the strokes were extremely vigorous, but he didn't deliberately pursue the artistic conception that penetrated the back of the paper. Three points her grandfather said that after a successful operation, there will be a taste of thunder on the ground. In the end, she didn't know anything about the formula, so she took the next best thing and began to concentrate on studying Zhao Jiadi's characters. She couldn't put it down, and Zhao Jiadi chewed the book with peace of mind. The Galois expansion at the end of "Abstraction", after the class bell rang, Mu Hongli flipped through the twenty-odd pages of notebooks, which were as dense and detailed as black clouds overwhelming the city, and couldn't help asking: "What is this?"

"The beginning of page 7 is the lecture records in the morning. The front part is the weighted estimation of some singular integral operators. I listened to it for free in an academic report in Fudan University. There are also some formula materials for minimal submanifolds and harmonic mapping. They are from Tongji University. An old professor explained a lot of private goods and benefited a lot, and the one I listened to in Fudan this morning was also good, and it didn’t waste time.” Zhao Jiadi patiently explained, if others’ mouths are soft and others’ hands are soft, Mu Hongli is selfless Contributing so many textbooks, Zhao Jiadi is also willing to tell her some professional things, so that she will not mistakenly think that she is playing some mentally handicapped trick to save the country by slapping a swollen face to pretend to be fat.

"The algorithm of the two-phase flow calculation model of the sand wall's wave-dissipating and energy-absorbing effect?" Mu Hongli deliberately turned to page 7, and finally reported a very awkward term. This notebook is no different from a heavenly book to her.

"I told you that you still don't understand." Zhao Jiadi chuckled and continued to study his Galois expansion.There was no disdain or contempt on his expression, but the smile on the corner of his mouth could definitely drive people crazy.

"Then explain it to me in the most concise and easy-to-understand terms, otherwise I won't be able to invite you to dinner." Mu Hongli, who was stepped on her weak spot, threatened softly.

"Do you really want me to explain?" Zhao Jiadi put down the "Abstract Algebra Basics" in his hand, and stared at Mu Hongli slightly sideways. Ever since he was "hooked up" by him, this child began to degenerate involuntarily, and now he even dared not concentrate on class. Yes, it really made the male teacher and the boys feel heartbroken.

"Tell me!" Mu Hongli said fearlessly, but she was actually very guilty.

"Really?" Zhao Jiadi laughed.

"Nonsense." Mu Hongli said bitterly.

"To put it simply, it is to study a solution algorithm for a two-phase flow equation that includes a strong source term. You can convert the problem into a conservation law problem and an ordinary differential equation problem through the splitting method and R transformation. For the conservation law, a finite Discrete solution in the volume format; for ordinary differential equations, aiming at the particularity of the problem’s high energy level, starting from the physical background of the problem, the right-hand term is divided into two parts, kinetic energy and internal energy, and the kinetic energy part is processed through the kinetic energy equation Analytically solve it, so a good overall numerical calculation effect has been obtained, well, after the explanation is over, I believe you know every word, as for whether you understand it or not, I don’t know.” Zhao Jia gave the first serious A simple and simple explanation, but it doesn't hide the narrowness in his eyes at all. The meaning couldn't be more obvious, little crush, don't play tricks in front of your uncle.

"Understood." Mu Hongli closed the notebook and said with a smile, as if infected with Zhao Jiadi's thick skin.

"A child can be taught." Zhao Jiadi did not expose the lies that both parties knew, and quietly accompanied Mu Hongli to two oral English training classes. The lecturer was very kind and privately regarded Mu Hongli as a proud student, so He also loves Zhao Jiadi, and let this guy hide in a corner and listen to Russian and read mathematics without any dispute.

After class, according to the routine and the tacit understanding cultivated by the two, he walked to the cafeteria, and Mu Hongli took out his meal card to invite him to eat. Now Zhao Jiadi, who has been promoted to a mysterious figure, has begun to gossip in college forums or some small circles. The flames were burning, and Mu Hongli didn't care much about it. Maybe it was because she was too out of the ordinary, and because she had a cold temper, the three girls in the dormitory were more envious of her than intimacy. A son who pretends to be a pig and eats a tiger like a rich second generation, and there are very few animals who are sour and mutter that every time he eats with Mu Hongli, he doesn’t pay for it. How could he be a rich second generation? split.In the face of these uproars, Mu Hongli is still calm and at ease. She is a girl who is used to sticking to the bottom line. From the beginning, she planned to be friends with Zhao Jiadi.

For the current Mu Hongli, the greatest expectation is to listen to Zhao Baliang play the erhu, because he joked that he had played the erhu for more than ten years, and when he fell down, he would go to the street to play the erhu in "Qinqiang Brand Song" To eat, maybe even be taken care of by a wealthy wife with sharp eyesight.

After the lights in the dormitory were turned off, Mu Hongli lay on the bed, took off her earplugs, turned off the earphones playing Russian recitation, curled her lips, playing the erhu was much more exciting than her playing the guitar.
