Do you understand Euclid today?

Lin Qianshu was awakened by the tempting smell of food.

He opened his eyes and sat up on the sofa, a blanket slipping from his shoulders.

"Wake up." Jiang Yizhi came out of the kitchen, looked up and saw him clutching the blanket in a daze, and said to him, "Come and eat, dinner is ready."

Lin Qian Shushu put down the blanket in a daze, put on his slippers and walked towards the restaurant.

There are three dishes and one soup on the table, and the dishes look quite attractive.Lin Qianshu, who had already made up his mind not to eat dinner, swallowed involuntarily, his stomach growling.

Jiang Yizhi handed over a pair of chopsticks in a timely manner, his eyes full of understanding.Lin Qianshu answered with a blushing face, thankful that he didn't say the word "not hungry".

The two sat down on both sides of the dining table. Lin Qianshu picked up the rice bowl and first put a piece of fried tofu into the bowl.

"After eating, take out the English vocabulary book on your table, and we'll start memorizing it from the beginning." Jiang Yizhi also picked up a piece of fried tofu, and said to Lin Qianshu in a casual tone.

Lin Qianshu almost choked on a mouthful of tofu.

His eyes widened in disbelief, and he pointed at himself: "Me? Recite words?"

"Well," Jiang Yizhi put down his chopsticks, raised his head and looked seriously at the young man sitting opposite him, "I thought about it this afternoon, and going abroad is still the best solution to the current problem."

"If you can restore your memory before going abroad, you can apply for MIT before you have time, and you can continue your studies without delay; if you can't restore your memory," Jiang Yizhi's eyes flashed vaguely, "then the United States has the world. The top memory therapist, we will go abroad to help you retrieve your memory."

Looking at Jiang Yizhi's serious expression, Lin Qianshu was stunned.

In terms of finding his memory, Jiang Yi Zhiyuan was more persistent than he imagined, and he used the word "we", as if vowing to accompany Lin Qianshu to the end on the road of finding his memory.

Such feelings were too heavy, and Lin Qianshu felt that he couldn't understand it.He sighed and couldn't bear it in his heart: "Jiang Yizhi... there's no need." He picked up the rice grains in the bowl, looked down at the half-bitten piece of fried tofu: "You don't have to do this, my life It doesn't make sense for you to be responsible..."

"What if I have to?" Before Lin Qianshu could finish speaking, Jiang Yizhi interrupted him unexpectedly.

The young man's eyes were burning, as if he wanted to burn everything around him.

Lin Qianshu didn't understand what happened between the two of them in the past seven years, which was enough to cause such a strong and fertile relationship to burst out from such a high mountain flower that seemed to be planted in the air.But in this strange world of seven years later, it was such a guy who firmly said that he was responsible for his life that made his chest burn.

Lin Qianshu took a deep breath, swallowing the inexplicable emotion welling up in his throat: "That's up to you."

In fact, it's not easy to get it, it's just that I'm still stubborn and don't want to blush too much.

"Since I still plan to go abroad, there are a few things I have to explain to you in advance," Lin Qianshu knocked on the table and said, "My current memory is only up to the first semester of the first year of high school, and I have to learn English from scratch Yes. Of course, my math is as bad as it was back then, and I am not qualified to lead the so-called high school math competition club."

Jiang Yizhi said: "I checked the information at noon. Amnesia is usually just the loss of a certain memory, not the loss of knowledge and skills you have mastered in a certain area. If you can't understand mathematics, it means you haven't connected the subject with your knowledge."

Looking at Lin Qianshu's confused eyes, Jiang Yi knew that the other party did not understand his explanation.He thought about it, and gave an example in another way: "This knowledge is like hidden files. As long as you find the correct password, they can be opened again."

"What's the password?" Lin Qianshu sighed with a headache, "It can't be 1234, can it?"

Jiang Yizhi pushed the plate of fried tofu towards Lin Qianshu's hand: "Mathematics is easy to test. As long as you simply understand the theory itself, you can quickly think of the solution to the problem."

Lin Qianshu remembered the wrong question he answered in class D yesterday morning and Jiang Yixing's disgusted eyes, and he didn't quite believe Jiang Yizhi's theory.But looking at Jiang Yizhi's persistent eyes, after thinking about it, it finally turned into a sentence of "I hope so".

"What about the math competition class? Guan Ming said that we took turns taking turns, and it will be my turn next time." Lin Qianshu asked.

Seeing that Lin Qianshu was finally willing to seriously discuss future plans with himself, Jiang Yizhi's mouth curved imperceptibly: "Society classes are held three times a week, which is not a lot. I will take them during this time, and you can help me approve some homework." good."

"Maybe your memory will recover after a while," Jiang Yizhi saw that Lin Qianshu still looked hesitant, and said, "Even if the memory doesn't recover, your math problem-solving ability should return to the level before the amnesia .”

"You're not a doctor, so you say it so firmly..." Lin Qianshu muttered, lowered his head to clean the rice, looked at the bowl and said, "If I can't recover, I'll resign. I can't always rely on you."

Before falling asleep that night, Lin Qianshu drew another horizontal line in the memo on his phone.Originally, this memo was written by him to commemorate the days when he crossed, but when the inspection results came out today, it became a memorandum to commemorate amnesia.

On the third day of amnesia, I found blood clots in my brain. Jiang Yizhi said that he would take himself to the United States, and for a long time in the future, he would have to speculate on the character design of "Mr. Lin". Very difficult.

Lin Qianshu turned off his mobile phone and put it on the bedside, covered his eyes with the quilt, and turned to look at the street lights faintly coming in from the window.

He didn't know if Jiang Yizhi in the opposite room was asleep at the moment, maybe he was facing the same moon with the same confusion and anxiety as himself.

When Lin Qianshu woke up the next day, Jiang Yizhi still prepared breakfast early in the morning, just waiting for him to eat after washing up.

The two ate breakfast in silence, washed the dishes, changed their shoes and went out. All the steps were the same as the previous two days.After getting on the bus and having nothing to do, Lin Qianshu asked Jiang Yi out of curiosity, "We used to be like this too?"

Jiang Yizhi seemed to be thinking about something with his head down, and after half a minute he raised his head as if waking up from a dream: "What?"

"That way," Lin Qianshu swipe at each other with his index finger, "Do everything well without talking."

"No." Jiang Yizhi shook his head, his eyes became gentle, "We will talk a lot."

"Then what do we usually talk about?" Lin Qianshu became interested, thinking that it would be great for the two of them to have a common language.

"Solving the Prisoner's Dilemma with Probabilistic Models, the Generalization of Cauchy's Inequality and the Aesthetic Thoughts of the Archimedes Spiral."

Lin Qianshu was dizzy, and felt three huge question marks spontaneously appearing on his forehead, and the only thought circling in his mind was "this is all a mess".He asked cautiously: "That... is there any topic that is more ordinary?"

Jiang Yizhi thought for a while, and replied: "There are also, for example, we will discuss the golden ratio of slices of buttered bread."

"Okay, okay, don't talk about it." Lin Qianshu made a "stop" gesture, "I really suspect that I have been pierced by human souls for the past seven years. I will participate in such a high-end topic Was it discussed?"

Jiang Yizhi couldn't help but twitched his mouth: "Wu Mu, you are much better than you imagined."

Hearing what Jiang Yizhi said, Lin Qianshu finally found a topic for the two of them to discuss: "By the way, I don't know yet, why do you call me Wood?"

Lin Qianshu doesn't have a serious nickname. Lao Lin and Ms. Ming call him "Xiaoshu", Qiu Yuanshan calls him "Shu'er", and other friends either call him "Brother Shu" or "Lin Qianshu". It sounds like a thousand miles away from his name, and I don't know how Jiang Yizhi came up with such a weird name.

In comparison, the "A Jiang" I called him was too normal.

Jiang Yizhi looked at Lin Qianshu firmly, as if he wanted to look into the depths of his eyes through his eyes.Lin Qianshu felt uncomfortable being looked at by such eyes, so he averted his gaze first.

"Sorry," Jiang Yizhi suddenly apologized, "I hope you can remember this by yourself."

The question was not answered, but in exchange for Jiang Yizhi's apology and meaningful eyes, Lin Qianshu touched his neck, and whispered: "If you don't say it, don't say it... I just asked casually, but it's not very serious. want to know."

The topic that Lin Qianshu tried to come up with was unilaterally rejected by Jiang Yizhi, so the rest of the journey was silent again.

When we arrived at the school, the papers from the competition class last night were already placed on Jiang Yizhi's desk, Jiang Yizhi flipped through the papers, picked out a few papers from the back and yelled at Lin Qianshu: "Are you going to approve these? He handed over a paper that he made himself: "Here is the correct answer, just follow along."

Judging by Jiang Yizhi's careful selection method, the selected papers must be the best in the competition class. There is nothing wrong with it, and the possibility of controversial steps is low.Lin Qianshu felt that even though he was a young man with amnesia, doing this was like questioning his IQ.

Although he knew that Jiang Yizhi's EQ would not have thought of this.

"Forget it, you don't need to find something for me to do." Lin Qianshu sighed, and glanced at the timetable that was pasted on the table in front of him, "I'm going to class D."

It just so happens that the next class in class D is mathematics. Instead of staying in the office and changing the papers that you can't understand, it's better to fight wits with the mentally handicapped brother. Maybe you can remember the so-called "password" that opens the door to mathematics knowledge .

Lin Qianshu went downstairs with a pen and a book, and met a young man in a tracksuit with a whistle around his neck on the way.

This outfit was so representative in school, Lin Qianshu knew it must be a physical education teacher just by taking a look.

At this moment, the physical education teacher was holding his stomach tightly with both hands, his face pale.

Lin Qianshu smiled at him, planning to bypass him and continue down.

At the same time, the physical education teacher saw Lin Qianshu who was greeting him, his eyes lit up, and he stretched out his hand to grab Lin Qianshu's sleeve without hesitation: "Great, Teacher Lin, you came just in time! Please help me Let's have a lesson!"
