Do you understand Euclid today?

Lin Qianshu felt as if there was a thread in front of him, pulling him to connect his "not very good at class" self with his former self.He knew that this was different from the conditioned reflex after careful preparation.

He seemed to see another himself standing tall and straight on the podium, teaching the students in the audience with a passionate tone.

The two selves merged gradually, and finally returned to calm, as if throwing a small stone in the middle of a calm pool of water.

After explaining all the content in the lesson plan, Lin Qianshu let out a sigh of relief, and threw the chalk into the slot: "Next, take out the paper that was handed out before class, and we can start working."

Jiang Yizhi nodded to him without showing any signs, and Lin Qianshu couldn't help grinning.

Soon Lin Qianshu couldn't laugh again - he noticed that Wang Siyu, who was sitting in the middle, stopped writing, and suddenly glanced to the left at a very fast speed, and his eyes seemed to fall right near Jiang Yizhi's seat.

The smile on Lin Qianshu's face disappeared in an instant.He straightened his face to Jiang Yizhi who was staring up at him, and cleared his throat loudly on purpose: "Some students focus on their papers, don't look left and right."

In the second half of the second class, some students finished the papers one after another, and brought them up to Lin Qianshu for correction. Lin Qianshu was not proficient in business, and the speed of grading papers was slow. Gradually, the people next to the podium stood up more and more. more.

Seeing this, Jiang Yizhi left his seat, walked to the podium, moved the stool and sat down, and called the names of the students at the end of the line: "Lin Xi and the six students behind you, come to me with the papers." correction."

The student standing in front of Lin Xi heaved a sigh of relief, congratulated himself for his good luck, and gave the students behind him a sympathetic look.

Lin Qianshu struggled in the pile of papers, and when he heard the voice, he gave Jiang Yizhi a grateful look, and secretly accelerated the speed of correcting and writing.

That's the end of a great event.Lin Qianshu thought that he would be so happy that he could think of a hundred ways to celebrate, but when he got home, he just wanted to take a shower and collapse on the bed, and he didn't want to do anything else.As he thought so, he held up his mobile phone and rolled on the bed, scrolling through Moments messages in a relaxed state.

As usual, the circle of friends was very lively. Qiu Yuanshan took photos of the delicious food and the girl looking at the camera shyly, and the words were full of love and affection.A few old classmates were posting company photos, with the words "Today is also an overtime day full of energy", and there was a bit of humor in the sadness.Rado sent nine photos in one go, with the words "We are the champions" complacently.

Lin Qianshu noticed a familiar figure in the corner of the first photo. He clicked on the picture to enlarge it. As expected, the person in the corner was Jiang Yizhi who was blowing the whistle.On the noisy sports field, Jiang Yizhi still maintained a stern look, which added a bit of coolness to the photo.After Lin Qianshu took a closer look, he accidentally long-pressed and chose to save the picture.

After logging out and scrolling down, Jiang Yixing, who hadn't been in the news for thousands of years, posted a post for the first time. Although there was no picture and only a full stop with unknown meaning, the comments below were definitely the most in the entire circle of friends.

Lin Qianshu added a lot of students from Class D, and the male students in Class D lined up question marks in unison. The radar scanned a full three rows, and asked Jiang Yixing: "Brother Jiang, have your account been hacked?"

Jiang Yixing replied "Idiot", and Jiang Yizhi immediately commented: "Don't swear."

... What a little guard of civility and etiquette.Lin Qianshu was speechless, but he still moved his fingers and gave Brother Jiang a thumbs up to commemorate his unprecedented circle of friends.

After a few seconds, the phone prompts that a new message has come in.Lin Qianshu retreated to the main interface, only to find that it was Jiang Yixing who sent him a message.

Jiang Yixing: "Did the radar call you for dinner tomorrow night?"

Didn't the two discuss it when they called for dinner?Lin Qianshu was stunned for a moment, but still replied, "Yes."

Jiang Yixing: "Oh."

Lin Qianshu held the phone and waited quietly for another ten minutes, but finally no more messages came from the other side.

So Jiang Yixing really just wanted to ask himself if he would go to dinner tomorrow.This... is really boring.Lin Qianshu put down his phone speechlessly, lifted the quilt to wrap himself in it, closed his eyes, and soon fell asleep.

Lin Qianshu finally told Jiang Yizhi about going out for dinner with the students of class D - after all, even the meal card was in the hands of the other party, so he really couldn't find a reason to eat alone at night.He said that the students in class D invited him to a dinner party, and carefully said that the other party only invited him as a teacher. After speaking, he watched Jiang Yizhi's expression nervously, for fear that he would be unhappy.

Jiang Yizhi always looked calm, unable to tell whether he was happy or disappointed.

"Go and eat," he said to Lin Qianshu, "I'll pick you up after eating, and we'll go home together."

It's fine if you're not sad.Lin Qianshu just swallowed "If you really mind me, I don't have to go", he swallowed it, and looked into Jiang Yizhi's eyes worriedly: "Actually, I don't have to go, after all, we are all high school students, I'm a little Out of place."

Jiang Yizhi twitched the corners of his mouth, thinking for no reason that half a month ago, Lin Qianshu had said to himself with a serious face, "I've traveled through time, I'm just a high school student", and now he said seriously that he was incompatible with high school students. But it is full of "want to go".

How could such a Lin Qianshu have the heart to be rejected by others?Jiang Yizhi said: "You go, I'll eat in the cafeteria."

Lin Qianshu looked at Jiang Yizhi several more times, and after confirming that he was not angry, he breathed a sigh of relief and skipped to the appointment.

At six o'clock in the evening, when Lin Qianshu walked into the box on the second floor of Zhuangyuan Restaurant under the leadership of the waiter, there was already a lively table full of people.Hearing the sound of the door being pushed, several people who were sitting behind the door also turned their heads and shouted at Lin Qianshu: "Brother Lin! You are finally here! Come quickly! We are going to starve to death!"

Lin Qianshu sat down in the seat reserved for him amidst the booing, only to find that Jiang Yixing was directly opposite him.

Jiang Yixing's eyes passed Lin Qianshu and fell behind him. Lin Qianshu subconsciously turned his head to look back, and found that there was nothing behind him.

Jiang Yixing withdrew his gaze, with an inexplicably foul expression on his face, and when he saw Lin Qianshu looking at him, he glared at him.

Lin Qianshu was very inexplicable: How did I provoke him again?However, Lin Qianshu didn't take Jiang Yixing's unhappiness to heart. After all, brother Jiang was unhappy 365 days out of 366 days a year.

The private room is a table for ten, except for the five members of the basketball team plus Lin Qianshu and Radar, Lin Qianshu noticed that the "Jiang Gekong" Xiang Xiaojun, who was always blushing when he spoke, was also present, and his gaze went to Xiang Xiaojun's side Voila, starting to wonder if something is wrong with the eyes.

The boy on Xiang Xiaojun's left was sitting upright. Did he reach out to help the blue glasses that fell down under the bridge of his nose?What surprised Lin Qianshu even more was that the smiling girl sitting next to Guan Ming turned out to be Wang Siyu.

How did these two people appear in the celebration banquet box in Class D?Not to mention Guan Ming, who would gnash his teeth whenever Jiang Yixing was mentioned, Wang Siyu, as a female student in Class B, would be a little strange no matter how he thought... Lin Qianshu looked at the two of them, and forgot to speak for a moment.

Guan Ming fixed his glasses, his eyes clearly caught Lin Qianshu's confused eyes, he smiled awkwardly at him, and said hello to him: "Lin, Teacher Lin, good evening."

Xiang Xiaojun showed a guilty look to Jiang Yixing: "I'm sorry, Brother Jiang... I didn't mean to bring him here. When I came out, he was staring at me. He must come with me."

Jiang Yixing glanced lazily in Guan Ming's direction, not caring whether he came or went.

Wang Siyu noticed that Lin Qianshu was looking at him, and smiled at him generously: "Mr. Lin, good evening."

"Lin, Brother Lin, Siyu was invited by me..." Radar saw Lin Qianshu staring at Wang Siyu and said nothing, thinking that Lin Qianshu was dissatisfied with Wang Siyu for not studying hard and came to eat, so he quickly spoke for her, "She put Come here when the homework is done!"

Lin Qianshu: "Oh, that's it." Actually, I didn't really want to know what she was doing.

There was a knock on the door, and the lady boss with a bright smile poked her head out from behind the door: "Handsome guys, are you ready to serve?"

Everyone is here, Radar nodded, and said to the proprietress: "Aunt Li, serve the food, we are all here."

Hot dishes were served one after another, and under the strict supervision of Lin Qianshu, the underage boys poured Coke and Sprite into their cups. Everyone raised their glasses to celebrate this victory that belonged to the teenagers.

As the only adult present, and the dishes were not very palatable, Lin Qianshu ate very restrainedly, and even missed every meal with Jiang Yizhi - at least with Jiang Yizhi, the dishes on the table must be delicious is delicious.

Just eating and chatting like this, the meal was coming to an end, and Radar took over half of the leftovers on the table, eating happily.

Wang Siyu still had tutoring classes at night, so she left the box early. While the boys were still busy, Lin Qianshu also got up one step earlier and went downstairs to check out. When she went downstairs, she found that the downstairs was a bit smoky at the moment. The breezy little gangster was sitting at the table with his legs crossed, puffing.

The strong smell of tobacco invaded the nostrils, Lin Qianshu covered his mouth and nose with his hands, frowned in disgust, and said to the proprietress in a low voice, "Madam proprietress, pay for the box upstairs."

The proprietress's expression was not very good either. Seeing Lin Qianshu's disgusted expression, she smiled at him apologetically, "It's 340 yuan in total, just give you a fraction, and just give me 340 yuan." She lowered her voice and said, "" Sorry, these people are all from the vocational school next door... In fact, they are quite nice."

Lin Qianshu remembered that when he was in junior high school, there were a few punks with yellow hair near the school. They wore flip-flops and ate and drank for free at the food stall every day, which made the old man of the food stall so angry that he dared not speak up.So he nodded understandingly to the proprietress.

While talking, there were chaotic footsteps at the stairway, and the teenagers who cleaned up the "battlefield" upstairs came downstairs.Radar saw Lin Qianshu standing next to the cashier at a glance, and ran down bluffing and said, "Brother Lin, it's agreed that we'll invite you, how dare you ask you to pay."

Lin Qianshu smiled, feeling like an adult for the first time: "You guys don't make money, so please."

The two were pushing against each other when there was a sudden "bang" sound on the stairs, and a male student in Class D yelled "Ouch, I'll go" and complained: "Xiang Xiaojun, you stepped on my foot... I'm trembling!" What are you talking about?"

The author has something to say: I will be on duty tomorrow and the day after tomorrow, I am really speechless...

But there should be an update~
