don't make trouble

Light drizzle, patter.

Holding an umbrella, Qin Monan walked leisurely on the campus path, followed by Qin Mozhen who looked like a big dog step by step.

Since the last time she got sick, she was diagnosed by Qin's mother as having a cold.In this season when even dogs don't catch a cold, Qin Monan won the honorable victory when he compared his character with dogs.

Because of Qin's mother's repeated instructions, Qin Mozhen became Qin Monan's little maid.Every day, he was ordered around by Qin Monan.

How are you feeling today, master?

Oh, I'm a little dizzy.

Master, do you want to drink medicine?

Oh, you pour me a glass of hot water.

Master, you haven't had lunch yet?

Oh, go and get me a meal, beef fillet with rice.

He can't take it anymore.Qin Mozhen glared angrily at someone in front of him who had been stunned for more than n days.

Beside the path not far from the two of them, a black and white puppy was lying on the wet lawn, the hair was a little wet from the rain, it was pitiful.

"Hey? Xiaozhen, why are you still lying here?"

"Xiao Nan, go back quickly, don't get caught in the rain."

The little dog was speechless, twisted his body, and changed his direction, not looking at the two neurotics who made fun of him.

"Pfft, Mo Nan, you guys are so funny."

A tall boy walked towards them holding an umbrella with an unstoppable smile on his face.

"Ah? It's Qingyi, it's nothing, we like to joke around."

Seeing Liu Qingyi being amused by them, Qin Monan was slightly embarrassed.He waved his hand at Qin Mozhen, signaling her to leave quickly.

"Xiaozhen, you go first, I'm with my classmates."

As soon as he finished speaking, Qin Monan, who was "ungrateful, ungrateful, and ungrateful", turned around and left his sister and Liu Qingyi mercilessly.

Qin Monan, who had gone far away, didn't see that Qin Mozhen had been staring at their farther and farther figures, abnormally calm.

After arriving in the classroom, Qin Monan sat on his seat, opened the exercise book in a calm manner, and seriously thought about a conic curve problem.

There is a conic whose expression is x^2+y^2=1, which is elliptical...Try to find the function expression whose radius is the distance from its focal point to the origin, and the radius is the focal radius.

Seeing such a question, he couldn't help laughing, how did he and Liu Qingyi get to know each other?

It was an afternoon, the sky was bright and the air was clear, and the wind was smooth.

He was also solving such a problem, and just as he was about to clear his mind and solve a general problem, a low-medium male voice sounded in his ear.

"Student, can you teach me how to solve this problem?"

Hearing a strange voice, Qin Monan raised his head and recognized that it was Liu Qingyi who had just transferred this semester.

I heard that this classmate is a repeat student. It seems that he failed to pass the college entrance examination due to a sudden illness in the college entrance examination. His grades are also very good, so he transferred from the regular class to their class in the last semester before the college entrance examination.

As a person who usually doesn't seem very talkative, a little silent or even bored, and has never seen him talk to others, why would he ask himself to teach him how to do the questions today, Qin Manan was wondering.

Liu Qingyi seemed to be able to see clearly what was going on in his heart, but he still had a humble expression asking for advice.

"Qin Monan usually gets the highest score in mathematics in the class during the quiz. Today I have a problem that I really can't do. Please teach me." He secretly observed his expression while speaking.

Qin Monan didn't notice Liu Qingyi's performance, and he couldn't help feeling a little ashamed when he heard him asking questions modestly, but he thought so much about others.

Although it didn't show on his face, he also enthusiastically and carefully analyzed his problem, from problem-solving ideas, problem-solving methods, to problem-solving steps.

Finally, he also told him a few problem-solving skills that he usually uses.

"Okay, is this problem easy to solve now, and you can try it yourself next?"

After Qin Monan finished explaining the questions to Liu Qingyi, he motioned him to do it himself.

After listening to his ideas for solving the problem, Liu Qingyi picked up a pen and solved it seriously, and finally came up with the correct answer, looking at Qin Monan with a grateful expression mixed with satisfaction.

Seeing him like this, Qin Monan scratched his head and laughed, satisfied that he could teach others.

After going back and forth in this way, the two taught each other how to solve the problems, told each other their own problem-solving skills, gained knowledge, and even gained friendship, the so-called friendship in the sea of ​​problems.

They must have been familiar at that time!Friendship made by doing problems.Now the two have similar temperaments, and they have become close friends who can call each other by their nicknames.

Qin Monan shook his head, thinking where did he go, hurry up and do the questions, do the questions and do the questions!

The weather in the last less than forty days is really weird, because the small town of Stalingrad belongs to the north-central region of the country. There are heavy snowfalls in the bright sunshine in the south, and spring-like seasons in the cold nights in the north.

A few days ago, the sun was shining brightly, mixed with the recent cloudy and rainy days. It was these prospective college students who were not in a hurry. There was still heavy rain in the university, and evening self-study was cancelled. , self-study, class, self-study...

But for Qin Monan, who was already familiar with doing any questions, these were a piece of cake. He was not affected by the nervousness of the college entrance examination, and he seemed to be handy.

It seems that he has forgotten all about what happened in the past few days, if he ignores his seemingly casual expression of looking at Fengling every day, worrying about gains and losses.

Even so, these days, that person, no, let's call it a ghost, never came again.

There was nothing in his memory like he said, he would always remember him, not even any traces of his existence beyond that night.

No, you shouldn't think about him anymore, Qin Monan thought so.

But even if you tell yourself like this, the evil smile at the corner of the mouth will still appear in your mind.

In order to divert his attention, Qin Monan finally called his close friend Liu Qingyi helplessly.

How did these two become good friends?In addition to the sympathy among the academic masters, there are also like-mindedness in other aspects.

As for other aspects, for example - this classmate also has a hobby of collecting ancient objects.

In fact, this isn't Qin Monan's hobby, it's just some recent events that forced him to come into contact with some ancient objects.

Therefore, thinking that Liu Qingyi likes to collect ancient objects so much, he also has a more or less understanding of some of these things, which may be able to solve the unsolved mystery of this string of wind chimes.

Qin Monan always believed that this string of wind chimes was the guy's hiding place.

Thinking of this, he saw that in the living room, Qin Mozhen, with his messy hair and biscuit powder falling on the corner of his mouth, looked panicked.

The figure flickering into the room hurriedly dragging her slippers, Qin Monan just stood quietly at the door of the room, staring dumbfounded at her bewildered look.

"Well, Xiao Zhen, what are you doing?!"

"I'm going, I'm ashamed in front of the young man, it's over, it's over!"

Qin Mozhen ignored his brother and fled into the house yelling.The face of a woman who pleases herself seems to be the appearance of a young girl who is unkempt and disheveled when she sees her sweetheart, panicked and bewildered.

"Why is the young master male god at the door of the young master's house, why does the young master appear in front of the young master male god like this?!"

Qin Mozhen, who was in a hurry to tidy himself up in the room, suddenly stopped, opened the door abruptly, turned to Qin Monan who was still in a daze, and said angrily, "Damn Xiaonan, why did the young man come to our house?"

"What is your male god?"

"It's that new school, Cao Liu Qingyi!! You don't even know?!"

"Liu Qingyi?! He's outside the door!!"

"Yes, the male god is still outside the door! Quick, Xiao Nan, go and open the door for my male god!" After saying this, Qin Mozhen closed the door of his room anxiously and helplessly.

Qin Monan also quickly walked to the door, opened the door, and saw Liu Qingyi with a dazed face, standing in the doorway in a daze, only came back to his senses after seeing him, and greeted him.

"Hi! What's the matter with...she?"

"I'm sorry, I didn't hear the doorbell just now. I'm sorry, come in quickly." He said and greeted Liu Qingyi into the living room.

"Would you like coke or black tea?"

"Black tea, thank you."

Passing the black tea brought out from the refrigerator to Liu Qingyi, he heard him tentatively asking, "Was that your sister just now?"

"Well, I was sorry just now, my sister didn't know it was you, hehe, hehe" Qin Monan smiled awkwardly remembering his sister's entire appearance.

"Haha, your sister is quite funny!" Liu Qingyi couldn't help laughing as if he thought of the same scene as him.

"Hehe, it's quite funny."

"I thought you two were a couple."

"what?"

"It was the last time you two were teasing the dog."

After Qin Monan's reminder, thinking of the scene at that time, the two of them laughed again. It was indeed quite funny every time.

After laughing, I remembered what I had to do today.

"What did you say you wanted to show me? What kind of ancient objects?"

Liu Qingyi's face was full of interest, and he went straight to the topic calmly.

Qin Monan also thought of today's theme, so he put away his smile, stood up with a serious expression on his face.

"You come with me."

The two entered Qin Monan's room together, and closed the door with a bang.

Here, Qin Mozhen put his ear to the door, and when he heard his brother's door, he knew that there was no one in the living room.

Quietly opened the door of his own room with a gap left, looked around, but found nothing.

With a sneaky look, he walked lightly to his brother's door, and slowly put his ear to his ears, listening to his so-called business.

I couldn't stop thinking to myself, what are these two people doing paying attention to the door in broad daylight?Is there some ulterior secret?

What secrets can the two boys have? Could it be that my brother followed the trend, he he he he he...he bent! ?

No, it's too dangerous, too dangerous, to be alone and widowed in the same room.

Qin Mozhen stopped sticking to the door, and kept wandering in front of Qin Monan's door, what the hell, should I rush in and save me... the male god.
