The next day, Wen Xu was forcibly woken up by his biological clock.

Because of drinking last night, Wen Xu felt a little headache the moment he opened his eyes.But fortunately, he took the hangover medicine given by Duan Chenyi yesterday, so he doesn't feel too uncomfortable now.

Wen Xu nestled on the bed for a while, holding his head like this, and then struggled to get up from the bed.

It's 7 o'clock in the morning on Sunday, it's time to wash up and go to work to teach Lin Qirui :).

The distance from the room to the bathroom is not too far, but because Wen Xu's body really can't bear the side effects of alcohol, he can only move forward slowly while leaning on the wall.It took 15 minutes to complete the washing process that originally only took 5 minutes.

But fortunately, washing his face with cold water still had an effect. When the cool water was poured on Wen Xu's face, he recovered a little from his original trance.

When Wen Xu came out of the bathroom, he just had a face-to-face meeting with Duan Chenyi who had just come back from outside.

"Morning." Duan Chenyi shook the breakfast he just bought in front of him, "Do you feel uncomfortable now? Does your calf still hurt? If you feel uncomfortable, I can help you and Lin Qirui take a leave of absence.You have a good rest today."

Looking at the person in front of him, Wen Xu subconsciously thought of his sudden emotion when he was in bed on the Internet yesterday.He raised his hand and rubbed his face with his cold palm, trying to calm himself down.

"No, I'm fine." Wen Xu adjusted his hoarse voice, "Lin Qirui is now in a very important stage of entering a higher school, and if I miss a class, it will easily delay my progress. I just go to class normally today, so I won'tI need to trouble you to ask for leave for me."

Hearing Wen Xu's answer, Duan Chenyi looked up at his mental state.

Wen Xu still had a layer of dark circles under his eyes, and he looked a little tired.It is estimated that I did not sleep well last night, and now I am quite haggard.

Duan Chenyi sighed, and didn't continue talking.He just put the breakfast he just bought on the dining table, and said to Wen Xu: "Well, Mr. Wen is really dedicated... If Lin Qirui knows about it, he should be very touched. I bought you breakfast,Eat something before you go to class, or you will be hungry later."

Looking at the various breakfasts on the table, Wen Xu hesitated for a moment, then nodded and said, "Okay, how much did you buy for me? I'll pass it on to you."

Duan Chenyi smiled and said: "These don't cost much, I'll treat you to eat, don't be polite to me."

Wen Xu pursed his lips lightly, and after a little thought, he sorted out the prices of all the food on the table according to the common market prices, and transferred them all to Duan Chenyi.

He also added by the way: "How can this work? I live in yours, wear yours and use yours. It's impossible for you to be responsible for the food now, right?"

In the next second, Duan Chenyi heard a message notification sound from his WeChat.

Clicking in and looking, it is the record of Wen Xu's transfer to himself just now, a little confused.

"Why did you transfer so much money to me?"

Wen Xu rubbed his nose, then added to Duan Chenyi: "These are the breakfast money here, and the money for sober medicine plus the various expenses I have spent in your house these few times, such asWater bills and disposable supplies.”

"In addition, you helped me too much with Lu Yuan before, and I already owe you a lot. I don't want to affect our relationship because of these things, so you can accept these small money."

"Relationship?" Duan Chenyi was a little helpless, "What kind of relationship requires you to divide the money so clearly?"

Wen Xu murmured, "A lot, for example, it's like this between friends. You helped me, so I can't take advantage of you all the time, right? Aren't we two friends? I think dividing this kind of thingBe clear, not only can you grasp the scale, but also prevent material conflicts from affecting the relationship between the two of us."

Duan Chenyi was about to say that as long as it's you, you can take advantage of me in any way you want, but when she heard Wen Xu's words: "Aren't we two friends?", those thoughts in my heart disappeared instantly.set fire.

Although very helpless, but also a little dumbfounding.But in any case, the relationship between the two people is indeed an ordinary friend.

Duan Chenyi didn't say anything else, just nodded according to Wen Xu's words and said: "Well...then, Mr. Wen, eat quickly, it won't be good if the breakfast gets cold after the meeting."

When Wen Xu finished his breakfast, it was almost 7:45, and there were still 15 minutes before Lin Qirui's class.

Wen Xu had just packed everything up and was about to say goodbye to Duan Chenyi after saying thank you.

Unexpectedly, Duan Chenyi walked up to Wen Xu with the key in hand, and said, "I'm just about to go out, so I'll see you off on the way?"

Wen Xu looked down at the time, and didn't want to argue so much with Duan Chenyi.After just saying sorry to trouble you, she followed Duan Chenyi out the door.

Duan Chenyi thought that with Wen Xu's experience of getting drunk yesterday, he would choose to sit in the co-pilot seat without hesitation this time.But unexpectedly, Wen Xu chose to sit in his back row without hesitation this time.

Before Duan Chenyi could get angry, Wen Xu explained: "I'm still a little dizzy now, and I'm not used to sitting in the front row staring at the traffic. Be quiet in the back, so I can take a rest."

Although it didn't sound like a serious reason, but seeing Wen Xu's mental state was indeed a little bad, Duan Chenyi didn't continue to make trouble in his heart.

After saying yes, he reminded Wen Xu to fasten his seat belt, and then stepped on the accelerator.

Duan Chenyi's time card was just right, and Wen Xu was delivered to Lin Qirui's doorstep on time at 7:59 in the morning.

But this time is different from the past, when the doorbell is pressed, it is not Lin Qirui who opens the door.But a woman with a gentle and elegant appearance.

Wen Xu looked at that face and thought for a while before realizing that this was Lin Qirui's mother.

Mother Lin smiled at Wen Xu, "Little Wen, you are here. My son is waiting for you in the room now, come in quickly."

Wen Xu nodded and agreed, then followed Mother Lin and entered the living room.

In sight, there is another middle-aged man sitting on the sofa looking at his mobile phone.He also nodded and greeted Wen Xu.

Lin's mother explained to Wen Xu in a low voice: "This is my lover, Lin Qirui's father. This should be the first time you have seen him."

Wen Xu greeted Father Lin with a smile, and was about to enter the room to start teaching Lin Qirui.

Hearing the doorbell rang again, Duan Chenyi, who had just parked the car and came out of the parking lot, stood at the door and greeted Father Lin.

"Uncle? Is your company on vacation today?"

Father Lin put down his phone and looked at Duan Chenyi with a smile, "Why are you here?"

Duan Chenyi shook the car key in his hand, looked up at Wen Xu and said, "Teacher Wen is my friend, and I happened to drop by to see him off."

Entering the room, Wen Xu looked at the game console on Lin Qirui's desk that he hadn't collected in time, and asked with a smile: "Your parents are here today, don't you try to behave better in front of me?"

Hearing this, Lin Qirui put away the game console in a hurry, and asked gossipingly, "Mr. Wen, did my brother send you to my house today?"

Wen Xu hummed, "Have you finished the homework I assigned you last week? Show it to me."

Lin Qirui still asked persistently: "Mr. Wen, did you rest at my brother's house yesterday? Otherwise, why would he drive you off on weekends when he is so free?"

"Lin Qirui." Wen Xu looked over expressionlessly, interrupting his desire to gossip.

"Now is the class time, don't talk about the content that is not good for the class."

Because Wen Xu specially reminded Lin Qirui to let him talk less about Duan Chenyi before class, so the topic of this class is very focused, besides mathematics, it is still mathematics.

And Lin Qirui finally made it to the end of get out of class seriously, and was about to continue gossiping about Wen Xu and his brother during non-class time, but Wen Xu happened to be invited to another room by Lin's mother.

Lin Qirui could only give up, and listened to the homework Wen Xu assigned to him before leaving with tears in his eyes.

Lin's mother is a very gentle person. She didn't ask Wen Xu how her child's study status was before she came up, but instead asked Wen Xu if she was still used to it when she was in class.

"My son's personality is sometimes a bit strange. He was angry with many teachers before. Now only you can persevere. Teacher Wen has a good temper and a good personality, and his teaching level has always been online."

"Lin Qirui's weekly test results last time have improved a lot compared to before. I am very grateful to Mr. Wen."

Wen Xu smiled, muttering in his heart that he was just doing things with money.But still cooperated with Lin's mother and praised Lin Qirui a few words: "Xiao Lin is a good boy, and he is also very caring when studying. The current result is the result of your hard work with me."

Lin's mother glanced at Wen Xu gratefully, "It should be, because now Xiao Lin is used to you coming to class every week. Our idea here is to pay off the fees for the whole year of junior high school in one lump sum. Can you trouble me?"Teacher Wen has been tutoring this child until the end of the high school entrance examination?"

To pay all the fees for the first three years in one lump sum...

Wen Xu lowered his eyes, thinking of the last time the teacher told him that he would arrange for him to go abroad as an exchange student in his junior year.

One class is 800, and there are more than a dozen classes in the second semester of the third year of junior high school, plus this semester, there can be a small 20,000 intermittently...

Twenty thousand yuan, plus Wen Xu's previous savings.It is not a problem to scrape together 50,000 yuan, and it is completely enough for him to live abroad for a period of time.

Wen Xu took a deep breath, nodded and agreed.

The tension in Lin's mother's eyes just now was replaced by happiness immediately, "Okay, okay, then I will transfer the money to you in one go later. Please, Mr. Wen, my child will need you a lot in the futureGuidance and guidance..."

Because Duan Chenyi was forced to stay for lunch by Lin's father, and Wen Xu just made an excuse that he had to go back to school first, so he came out early alone.

Wen Xu, who came out of Lin Qirui's house, was slightly relieved.By the way, was glad that Lin Qirui's parents were present today, otherwise, don't know what kind of method Duan Chen would think of to be left behind for dinner.

Although Wen Xu looked indifferent and tough on the surface, he just couldn't bear Duan Chenyi's way of entanglement with him after being wronged.Soft-hearted, easy to be led by the nose by Duan Chenyi.

He rubbed his cheeks to calm himself down a bit, then took out his phone to contact Chen Chen.

"Are you there? I will accompany me to a library later. I want to find a book."

After sending the message, Wen Xu stuffed his mobile phone back into his pocket, and then walked towards the school.

And when Wen Xu just walked to the door of the library in Zhuda University, the mobile phone that was originally in his pocket vibrated.He took it out and saw that it was a new message from Chen Chen.

"I'm on the fourth floor of the library, what book are you looking for?"

Wen Xu lowered his eyes, hesitated for a moment, and then sent a message: "Wait for me on the shelf of medical books on the fifth floor, I will be right there."

Under Wen Xu's guidance, Chen Chen rummaged through the entire bookshelf before barely finding a few popular medical science books.

"So... you specifically asked me to come up here to find this?" Chen Chen found a unit about the heart by relying on the catalog, and asked Wen Xu with some doubts, "Why don't you go to Baidu? Isn't that thing faster?"

"Baidu can't believe everything." Wen Xu frowned slightly, suppressed his voice, and explained softly to Chen Chen: "Last time I had a stomachache, and Baidu told me it was stomach cancer... or it was only three months before it was put into the box."That stomach cancer."

Wen Xu took the book Chen Chen handed over, "I want to know a more comprehensive explanation, and by the way, I can broaden my knowledge."

Chen Chen laughed angrily at Wen Xu's words, "No, if you feel that your heartbeat is irregular, go to the hospital and take an X-ray. If you find any problems, treat them as soon as possible. What kind of operation do you go to the library to find information books and studyah?"

Seeing Wen Xu's behavior, he couldn't help but complained: "Wen Xu, are you stupid in reading? How about when I go to the hospital to register for you later, how about a brain department?"

Wen Xu touched the tip of his nose with a guilty conscience, "No...my heartbeat was irregular for a while. There is no need to go to the hospital to occupy medical resources."

Chen Chen sighed helplessly, "Then tell me, under what circumstances did your heartbeat become irregular? Did you just finish strenuous exercise?"

"No." Wen Xu shook his head, hesitated for a moment before telling Chen Chen honestly, "I had just finished drinking, and I was with Duan Chenyi. I happened to be looking at him..."

Hearing Wen Xu's answer, Chen Chen looked up at him in shock.

The two looked at each other for a long time before Chen Chen couldn't hold back and smiled.

"Stop looking for information books." Chen Chen showed an expression of resentment, "Go and stay with Duan Chenyi for a few more days, maybe the frequency of irregular heartbeat will gradually increase."

"At that time, you will probably be able to find the correct answer."

Wen Xu looked at Chen Chen in confusion, "...what are you talking about?"

Although not supported by Chen Chen, Wen Xu insisted on borrowing a few books with similar titles: "The Secret of the Heart" and "One Hundred Things You Want to Know About the "Heart"" to take back to the dormitory to study carefully.

Before Wen Xu left, Chen Chen watched his movements and shook his head, "I didn't expect that one day, the saying that mud can't support a wall can be applied to you."

Wen Xu weighed his schoolbag, and smiled with satisfaction after feeling that the power of knowledge made his schoolbag a little heavier, and didn't listen to Chen Chen's words.

He just turned to Chen Chen and said, "Thank you, without your help, I wouldn't have found the book I wanted so quickly."

Chen Chen couldn't get rid of these words, he waved his hand unnaturally and said to Wen Xu: "Okay, okay, you can go back, I suggest you read these books with Duan Chenyi. Maybe he also read these books at that time."Arrhythmia."

"If the two of you find the answer in the book together, you can sit in front of the doctor and ask him about the treatment together, and you can save medical resources. It's fast and efficient, it's the best of both worlds..."

After returning from the library, Wen Xufan didn't bother to eat, and started to study seriously in the dormitory with a few borrowed books.

He carefully read the chapter on arrhythmia thoroughly. After knowing several causes of arrhythmia, Wen Xu ruled it out a little, and could only find one reason related to his situation at that time.

A tachyarrhythmia caused by mood changes.

Mood changes?

Was it caused by calf cramps at that time?

Wen Xu's grip on the pen tightened slightly, but he was still a little puzzled.

He had had calf cramps many times before, but never once did he feel like his heart missed a beat like last time.Still very strong.

He lowered his eyes and wrote down two different external situations at that time and before on the draft paper.

The first is mood changes caused by alcohol.

The second type is emotional changes caused by Duan Chenyi.

Wen Xu sat down in front of the table, took a pen to paint and draw for a while, and then focused on drawing key symbols under the two words "alcohol" and "Duan Chenyi".

By the way, the four words "to be confirmed" were written next to it.
