Thanks Bumin

"A particle can only do work by the force of the electric field during its motion, so the velocity is the highest at the highest point of the orbit, and its y coordinate is represented by ym. According to the kinetic energy theorem, there is..." The fingers with sharp bones hold the pen and draw two or three times on the paper What a picture, "Look, it's easy to solve this way."

Xie Jing restrained himself from looking at those hands, put all his attention on the connection between the equation and the diagram, and tried to follow the other party's train of thought to understand.

Rong Min turned the pen carelessly, the light in his eyes was focused on Xie Jing all the time, Xie Jing frowned and tried hard to think, he didn't urge him, just waited quietly.

After a while, Xie Jing's tightly knit brows finally loosened. He tried to write down the formula himself, and then explained it again. He carefully glanced at Rong Min, and hesitantly said, "That's right."

The corner of Rong Min's mouth raised, and he reached out to rub Xie Jing's hair, "That's right, you're right."

He picked up a pen and changed a few conditions and data from the question just now, and pushed it in front of Xie Jing, "You try to solve this question again."

Xie Jing finished reading the topic while biting the tip of his pen. After contemplating for a moment, he began to write in a hurry. When he encountered a bump, he pushed the conditions back and forth, drew a sketch, and finally solved it after a while.

Xie Jing anxiously watched Rong Min help him correct the question.

Rong Min's finger clicked over the calculation formulas, his slender fingers looked like a landscape, but Xie Jing didn't care to appreciate it, he stared at Rong Min's expression, and asked impatiently: "How is it? How is it? Where is wrong?"

Rong Min shook his head, with a sullen face and did not speak.

Seeing Rong Min's appearance like this, Xie Jing felt as if his heart was being grabbed and pulled, and the huge sense of loss and frustration was overwhelming him like a tide.

He shook the corners of his mouth, but his face was smiling like crying, "Then tell me what's wrong again."

Rong Min stretched out his big hand to Xie Jing, Xie Jing was stunned for a moment, he didn't dare to move, he just watched him make a gesture, and then flicked.

"Bah, it hurts, it hurts so much." Xie Jing held his forehead and gasped continuously, not caring about "respecting the teacher" raised his head and glared at Rong Min angrily.

A smile flashed across Rong Min's dark eyes, and he stretched out his hand again, Xie Jing turned around vigilantly to protect his forehead and refused to be fooled again.

The hand covering his forehead was pulled away without hesitation, and Xie Jing, who had a premonition of the pain coming again, closed his eyes tightly, with a heroic look, "Forget it, it's a punishment, you come."

The pain in the fantasy did not come, but a touch of coolness moved on the forehead. This feeling... Xie Jing thought suspiciously, why it looks like someone is caressing his forehead! ! !

Xie Jing opened his eyes, and happened to meet Rong Min's eyes, he keenly caught a trace of distressed emotion, and was about to take a closer look, but only saw the reflection of himself flushed.

Only then did he react, he leaned back, avoiding Rong Min's fingers, "You, you..." He didn't know what to say, this action was too ambiguous.

Rong Min pursed his lips and frowned, his innocent appearance seemed to be still doubting Xie Jing's sudden reaction, "I'm sorry, I was too strong just now, your forehead turned red."

That's why he touched his forehead, it was an apology, Xie Jing suddenly realized.After he breathed a sigh of relief, he felt embarrassed for himself, because the other party's reaction to this action was so sensitive, no matter what he thought, he was the one who had ambiguous thoughts.Coming to such a conclusion, Xie Jing only felt that the piece of skin on his forehead that had just been stroked/touched was burning hot.

"It's okay, it's okay, tell me what's wrong here." Xie Jing lowered his head and changed the topic.

"No mistake, you got this question right."

Xie Jing was stunned, "Then what did you mean by shaking your head just now?"

Rong Min was confident, "You asked me where I was wrong, but I was right, of course I shook my head."

"You..." Xie Jing felt that he was really stupid. Rong Min didn't say anything when he saw that he had misunderstood. It was obvious that he was trying to play him. Fortunately, he was still so sad, and felt sorry for Rong Min's advice all morning.

The more Xie Jing thought about it, the more his teeth itch with hatred, and he crunched his fingers under the table.

Seeing that Xie Jing's expression was wrong, Rong Min hurriedly pointed to a question on the exercise paper, and said seriously: "Stop making trouble, stop making trouble. Look at this question, it's more complicated than the previous one, try it out and see if you can do it." cannot."

…………

"Okay, it's getting late, let's stop here today."

Xie Jing reluctantly raised his head from the draft paper, looked out of the window, and before he knew it, the sun had already set half way down, and the afterglow cast a light golden tulle on the scenery outside.

He got up and stood in front of the window, took a deep breath out of the window, clasped his hands and stretched his waist, with the hem of his clothes pulled up to reveal a waist, the whiteness that has not been exposed to the sun much, with the unique blueness of a teenager Bitter and weak.

When Rong Min's eyes touched the waist behind him, darkness slowly flooded into his eyes, just like the darkness and darkness of a wolf staring at its prey.When Xie Jing turned around, his eyes immediately returned to normal.

"Let me treat you to dinner." Xie Jing put his hands on the back of the chair and said to Rong Min who was packing his schoolbag.

Rong Min paused, "Why do you want to invite me to dinner?"

Seeing that Rong Min didn't refuse, Xie Jing had a smile on his face, "You come to give me tutoring, and I treat you to a meal, no matter how you look at it, it should be deserved."

"Okay." Rong Min readily agreed, "Tell me, where do you want to invite me for dinner?"

"How's Xia Cheng's little chef?" Xie Jing was definitely in pain when he said this.

Xiacheng Kitchen is near the attached middle school. It's not a high-end restaurant, but it's not something that students can spend casually. Generally, no one in the attached middle school goes there except from a particularly good family background.Thank you Jing for mentioning Xia Cheng's little chef, it is full of sincerity.

Rong Min smiled and shook his head, "No, I don't want to go there."

Xie Jing's expression immediately turned bitter. Haha, Xia Cheng's kitchen is already his biggest budget. For today's meal, he deliberately brought all the pocket money he had saved for a long time with him. If Rong Min wants to go to Junlai , Deshui Pavilion or something, his money is not enough to pay for a dish.

Seeing Xie Jing's sudden change of expression, Rong Min found it funny, took Xie Jing's shoulders, and threw his schoolbag to him, "Let's go, I want to eat sand tea noodles, please treat me to Wang Ji's."

Stir-fry peanuts, sesame seeds and various materials, grind them and cook them into a thick and delicious soup. Put them in a large pot half the height of a person and keep heating them. There are various ingredients such as seafood, meatballs, bone-cut meat, etc., topped with a few tablespoons of soup, and a bowl of the highest representative of Xiacheng's delicious snacks, Shacha noodles are fresh out of the pot.

Xiacheng people's love for sand tea noodles can be seen from the popularity of sand tea noodle stalls that can be seen everywhere throughout the year.However, when it comes to the best food, all the authentic Xiacheng gourmets know that it belongs to Wangji's.

Under the old banyan tree, a small car, an old couple, and a few simple small tables were set up. The sales started around [-] o'clock and closed at [-] o'clock in the morning. His family's business was full almost every moment.

"Ah! It's delicious." Xie Jing took a sip of the soup, holding the bowl, squinting his eyes in satisfaction, "Wang Ji's Sand Tea Noodles are really the best."

Rong Min didn't focus on eating, he spent most of the time looking at Xie Jing.

"Xiao Jing, why are you here?"

A pleasantly surprised voice sounded, Xie Jing lowered the corners of his mouth reflexively, he glanced at Rong Min who was drinking his soup with his head bowed, and reluctantly said to the visitor: "Come and eat, you are here too."

If Rong Min wasn't in front of him, he didn't even want to answer.He wasn't afraid that Zhao Jiaxuan would yell about his abnormal grades, there was no basis for it, and there were so many people here, with Zhao Jiaxuan's big personality, he wouldn't tear himself apart here.He responded with a few sentences just to make Zhao Jiaxuan more interesting and stay away from them.

Zhao Jiaxuan didn't hear the impatience in Xie Jing's words, and continued to say enthusiastically: "Well, we went to school to play basketball together in the afternoon, and come to eat in the evening." Seeing that Xie Jing didn't respond, he seemed to be casual Said: "Did you know? Xu Kangrui has also entered Class [-]."

Xie Jing froze for a moment because of these words, he lowered his head for a long time without making a sound, and it took a long time before he managed to say: "Really?"

Zhao Jiaxuan chuckled, "Are you talking about fate? We are in the same class in junior high school, and we are in the same class in high school. Now that we are divided into classes, we can still be divided into one class."

In order not to tremble, Xie Jing tried his best to bite the tip of his tongue, and soon, a fishy sweetness filled his mouth, but he felt the rust-like salty taste bitter to his heart.

Xie Jing didn't speak, the scene was a bit awkward, Zhao Jiaxuan could only turn the conversation to Rong Min, "Hello, I'm Xiao Jing's classmate."

When Rong Min heard Zhao Jiaxuan intimately address Xie Jing as Xiao Jing, his eyes narrowed dangerously, so fast that Zhao Jiaxuan couldn't see it at all, and the corners of his mouth curled into a perfect arc, "I'm Xie Jing's friend." He didn't say his name, and made it clear that he didn't want to get acquainted with Zhao Jiaxuan.

There was nothing to say between the two sides, so Zhao Jiaxuan had no choice but to return to his own table resentfully.

Qiu Qi glanced at him dissatisfied, "What's the relationship between you two, aren't you familiar with each other? You've been talking for so long."

Zhao Jiaxuan smiled, "We're all classmates, just say hello."

"Cut!" Qiu Qi disdainfully ate the noodles.

Zhao Jiaxuan and Xu Kangrui, who was smoking silently, looked at each other, then turned away silently.

After Zhao Jiaxuan walked for a long time, Xie Jing slowly woke up from the shock he brought him.God knows how much he wanted to stay away from that person, knowing that he would be in the same classroom with Xu Kangrui for a year, this news made him painful and irritable.

Rong Min silently watched everything, he didn't say much, just handed the tissue to Xie Jing, "I'm done eating, let's go."

"Oh." Xie Jing stood up immediately, his knee still hit the table, he didn't care about rubbing it, it was Rong Min who helped him quickly.

When Xie Jing grabbed Rong Min's clothes and wanted to leave, Rong Min's eyes turned to a certain direction, and there was also a pair of eyes looking at him, vicious and bloody.

Rong Min curled his lips, looked away indifferently, and walked away with Xie Jing's shoulders on his shoulders.

At the intersection of parting, Rong Min said to the absent-minded Xie Jing: "Xie Jing, I can feel that you have a good relationship with that classmate just now, right? You have been out of shape since he came here just now I don't want to blame you, I just want to say to you." The nervousness and anxiety in Xie Jing's eyes made Rong Min sigh softly, "Don't be afraid, no matter what happened between you, I will always stand with you of."

Before he finished speaking, he stretched out his hand to give Xie Jing a very short hug, and let go after just one touch.

Under the street lamp, Xie Jing stared blankly at the back of Rong Min walking away, and suddenly grinned.
