Fortunately

"Is there anything else you don't understand?" Yu Chen asked like a teacher after explaining a question.

Lu Ling quickly went through the steps of solving the problem in his mind, then shook his head, "No more."

Originally, a question that I thought was extremely difficult, as inviolable as a god, was explained by Yu Chen, and I suddenly felt that it was not that difficult. It was just that I didn't think about it and fell into a predicament.And the entry point of this problem-solving is not particularly novel, it is the level that can be mastered by oneself.

For this reason, Lu Lingyou felt that Yu Chen was really amazing.He thought about this question for a long time without making any progress, but Yu Chen just glanced at the question and immediately solved it.

Lu Ling did the questions on his test paper according to the ideas explained by Yu Chen.

Watching someone else solve a problem is completely different from doing it yourself.When watching other people solve problems, because the other party's thinking is coherent and clear, it is very easy to keep up with the other party's pace and understand the original meaning of the problem.But when it’s your turn to solve the problem, there is no one to point you around, and you have to repeat your thinking step by step by yourself, because you learn it from others, not from yourself, and you often need to break your own inherent thinking, so this The process was extremely difficult.

It is myself who cleans up the dead branches and grasses in my mind with my bare hands.

Fortunately, Lu Ling's comprehension ability is excellent. Although there were still some stutters during the process, the questions were still completely answered in the end.

After solving the problem, he looked at the screen, there was no hang up, and Yu Chen had been out for some time, and now he was leisurely drinking a straw with a box of lemon tea in his hand.

Lu Ling also sharply saw all kinds of expansion-packed potato chips in the corner of the screen.

...he really loves snacks.

"I hung up." Lu Ling said.

Over there hurriedly said, "Don't."

"Is there anything else?" Lu Ling asked.

Yu Chen put the lemon tea on the table, randomly picked up a bag of potato chips and opened it.

"Lu Ling, my dream is to be a people's teacher. I just had my first student, and I haven't had enough teaching yet, so you let me hang up, so cruel..." He said while tearing it apart. .Then he tossed a piece of potato chips into his mouth, chewing until it clicked.

Especially in such a quiet environment, when the transmission is transmitted through the mobile phone, and the current is applied, it is magnetic, which has a different feeling.

Lu Ling pursed his lips. In fact, it’s good not to turn off the video. Right now, I’ve just started writing the test papers and encountered difficulties. I don’t know how many more questions I can’t solve. If you understand, it will be very helpful.

only......

He raised his eyes and said, "It doesn't matter if you don't close it, then you are not allowed to make a sound."

"Of order." Yu Chen hurriedly put down the two potato chips he had eaten, took out a tissue to wipe his hands and mouth, and said obediently, "I promise to be quiet."

Lu Ling hummed, bowed his head and continued to do his homework, letting the video play.Occasionally, when encountering a problem that still fails after thinking about it, just ask the person on the other end of the screen.

Whenever at this time, Yu Chen would look up from a stack of test papers, and ask with a smile on his face, "Look, am I useful?"

And Lu Ling would always hum in a low voice, hiding a little bit of shyness.

"Brother Chen, it's late..." Lan Xu poked his head in and saw that Brother Chen was videoing, he was so shocked that his jaw almost dropped.

Yu Chen turned his head, cast his displeased eyes in a straight line, "Didn't you remember to knock on the door before telling you to come in?"

"Uh," Lan Xu was startled guiltily, then walked out from behind the covered door, approached Yu Chen naturally, touched his head in shame and said, "Brother Chen, you also know that I have a bad memory, I forgot Already." While looking curiously at the screen of the mobile phone on the table, he couldn't help it.

"I have something to talk about." Yu Chen turned around and blocked Lan Xu's sight without any trace.

After Lan Xu was slightly stunned, his curiosity was aroused even more.Who are you videoing with, and you still don’t show it mysteriously... Ah, can’t you?Could it be that brother Chen already had a girlfriend before he knew it? !

The good brothers who promised to go together, how could he get out of the order first!

The more Lan Xu thought about it, the more shocked and frightened he became.

"Brother Chen, I just came to ask you how we would like to order takeaway for dinner." Lan Xu nestled on the bean bag sofa by the window, pretending not to be curious anymore.

"Okay." Yu Chen agreed without hesitation, "It just so happens that my parents are away on business this week and won't come back."

"OK." Lan Xu got the answer, got up from the sofa, walked out, and relaxed Yu Chen's vigilance, "Then I continued to play games with Lu Yu, only to find that his game skills are almost as good as Brother Chen's, If you have time, you two can solo."

Yu Chen watched him walk a few steps away, tapped his toes on the ground, turned the swivel chair and turned back, and responded casually, "I'll talk about it when I have a chance."

Very perfunctory.

He looked at the screen and said to Lu Ling who was still there, "Okay, he's gone. Let's continue the lecture."

lecture?Lan Xu paused, ah, it turned out it wasn't what he thought, and his face immediately showed joy.But after a quick second thought, it's not right, who has such a big face to invite Brother Chen to give a lecture in person.You know, brother Chen has never given him a question, nor has he given a question to anyone else.

He turned and squatted down, then landed on all fours, tiptoeing forward at the speed of a sloth.

"I thought you would die, but you didn't. Are you reluctant?" Seeing Lu Ling obediently immersed in solving the problem, Yu Chen curved his lips jokingly.

"..." Lu Ling paused while holding the pen, and then rolled his eyes at him.

Yu Chen burst into laughter after being stunned, and fell back on the back of the gray-blue soft sofa, "I find that you are becoming less restrained in front of me now, and you often ignore people and say nothing, and you have even learned to roll your eyes."

Lu Ling pursed his lips and opened his mouth, "If you don't talk about the topic, I will hang up."

Yu Chen returned to seriousness, and continued to talk, "I'm afraid you can't do it, I'll talk about it now."

With a hook of his foot, he pulled the seat closer to the table. He wrote down a formula on the white paper and began to explain it seriously, "This question needs to use a variant, which is more flexible. You can put this..."

When Yu Chen was talking to Lu Ling, Lan Xu had already slowly crawled behind the seat in the form of a beast.He shook his hands and feet, stood up awkwardly, and said suddenly, "Who is it?"

Lan Xu suddenly appeared in the camera, and Lu Ling was startled.

Yu Chen couldn't stop him, and Lan Xu saw the phone interface.

Lan Xu let out a sigh, feeling a little disappointed that he couldn't catch something, "It's Lu Ling..."

Lu Ling in the camera nodded to him, "Hello."

It's a greeting.

Through the screen, he saw someone crossing his chest and frowning, his complexion suddenly turned bad, Lu Ling kindly pointed behind Lan Xu, and reminded him, "You'd better look back..."

Then Lan Xu reacted belatedly, and slowly turned his head.Facing Yu Chen's stern and stern gaze, he knelt down with a snap, and his knee hit the floor with a thud.It hurts to hear Lu Zero on the phone side.

"Brother Chen, I was wrong." Lan Xu put his hands on his lap, respectfully and honestly, humbly begging for mercy in an attitude of letting others slaughter him.

Yu Chen glanced at him coolly, without being angry and pretentious, "You kneel down for me first, I will finish this question first, and then I will deal with you."

Lan Xu knelt obediently, not daring to complain.

"Well, let's continue." When facing the camera, Yu Chen put on another friendly face.

Just by hearing the voice, he could tell he was talking with a smile. Lan Xu curled his lips while kneeling, thinking to himself, brother Chen is treating them nakedly differently!

"Uh, is this okay?" Lu Ling couldn't ignore the scene just now, not to mention that Lan Xu was punished to kneel more or less because of him.

"It's okay," Yu Chenwen wrote down the score points for the next step with a smile, "Don't pay attention to him, Lao Xu is an itchy person. Let's continue the topic, halfway through the talk just now,..."

After Lu Ling patiently finished explaining the questions, Lan Xu's legs were almost numb.

Yu Chen took a sip of lemon tea and said to Lu Ling, "Wait for me first, I'll go clean up someone and come back."

Cleaning up, this word is very easy to imagine, and it is also easy to associate with the scene of bloody suppression with fists.

Thinking of the violent scenes in various comics he had read, Lu Ling persuaded him, "Let's forget it... To be honest, he didn't make any big mistakes."

Yu Chen had already stood up from his seat, and he said softly, "Relax."

Then he hooked his fingers, beckoning Lan Xu to follow, and strode out the door.

Lan Xu stood up on the floor, rubbed his knees, looked at the camera and said solemnly to Lu Ling, "Remember to tell my relatives and friends that I love them."

That posture is as if you are going to die heroically and never come back.

"..." Lu Ling remained silent, dimly feeling that Lan Xu seemed to be having fun?

Lan Xu followed Yu Chen out of the bedroom and was taken to a corner of the living room.

"Stand by this wall and think about it. Don't leave without my permission." Yu Chen pointed.

"Brother Chen, can I just stand for half an hour?" Lan Xu said flatteringly.

"Half an hour?" Yu Chen faked a smile, and Lan Xu's big eyes immediately glowed with hope, and in the next second, Yu Chen shook his head and said firmly, "It's a beautiful idea."

Lan Xu curled his lips, turned around and faced the wall, thinking about his past.

He didn't resist, and looked very honest and obedient on the surface, but what Lan Xu was thinking at this time was that Brother Chen wouldn't be here to watch him all the time anyway, and when Brother Chen left, he would play with his mobile phone to pass the time, haha, he can What a witty little genius.

"..." Yu Chen looked at his big restless eyes that were obviously planning other things, and suddenly felt speechless.

He walked around from Lan Xu's left side to the right side, folded his arms to teach him a lesson, and hit Lan Xu's head with light words like a knife, "You have grown up, you have learned how to play tricks on me, let you go out If you don't go out, you still secretly hide and eavesdrop?"

"Brother Chen, I'm delusional. I was wrong. I was wrong." Lan Xu admitted his mistake with a good attitude, praying in his heart that Brother Chen would leave as soon as he finished his lesson. He likes to play with his mobile phone.

The excuse that dispelled Brother Chen's vigilance before was not fake. He did make an appointment with Lu Yu to play games together later.

But now, it is estimated that the agreed time is approaching.

Yu Chen narrowed his eyes and sneered, "Hand over the phone to me."

"...No, no need." Lan Xu felt guilty.

Yu Chen didn't say a word, just looked at him lightly.

Lan Xu couldn't bear the threat, and took out the phone from his pocket and handed it over.

It was taken away by Yu Chen and confiscated.

"You just stand." He left the sentence and went back to the bedroom and closed the door.

Tulu Lanxu stood alone in the corner.

"..."

Lan Xu shouted in his heart: It would be really difficult to face the wall without a mobile phone...
