After a hard study and struggle, Ning Wenru finally finished his exams! Pang Zaiyuan from a different class also only had one exam left and a report on his microcontroller project to complete before he could go home for the holidays.

Ning Wenru, who had nothing to do after the exam, finally had some free time to surf the Internet and write. He finally logged into the Penguin after a long time, but he didn't have the courage to open the welfare group to take a look. He opened the outline and the manuscript document reluctantly, picked up inspiration, thought hard, and worked hard to write.

After all, Ning Wenru was busy with competitions, exam preparations, and her boyfriend. She hasn't updated for two months... He dug a hole and posted a few chapters before running away. According to the past situation, there must be a blackened little angel who would send him razor blades, whips, and candles! Now, Ning Wenru not only dares not to go to the welfare group to take a look, but also dares not to go to Jinjiang to read the comments. In the past, he always updated first before he dared to read the comments, and he was completely afraid to bear the resentment from the little angels.

Ning Wenru, who has an obsession with finishing, wants to update, but the plot of this fancy confession has been left for too long and is no longer cute. If it weren't for the outline, I would have forgotten most of the plot, and my handwriting is not fresh after not writing for too long. My typing speed dropped from 1000 words per hour to 500. So Ning Wenru made up his mind to practice writing every day in the future! Even if he is too busy, updating 100 words a day is also an update!

After spending several hours on a chapter of 3,000 words, Ning Wenru finally succeeded in updating. At this time, Pang Zaiyuan came back from the exam with dinner. While eating, Ning Wenru held his phone and read the comments, and found that no one had sent razor blades, whips, or candles! The urging for updates was also "Pity Da Mumu, good luck on the exam, mumu", etc., especially angels.

Ning Wenru was deeply surprised by this, and opened Penguin again to look for his own welfare group.

Because he hadn't been online for a long time, Ning Wenru only just now noticed that his welfare group had changed its name again, from [Happy Birthday, Da Mumu] to [Da Mumu takes a month off to prepare for the exam].

Pang Zaiyuan was sitting next to Ning Wenru and eating together. He also saw the welfare group on Ning Wenru's phone screen and said, "I have already asked for leave for you. Isn't that thoughtful?"

Ning Wenru's eyes were filled with gratitude: "How thoughtful! This is the first time I have not been whipped after a break!"

Pang Zaiyuan nodded slightly, put down his chopsticks, put his hands on his knees, and said seriously: "You should thank me for feeding you."

"Okay, I'm considerate and easy to manage," Ning Wenru followed suit and used Pang Zaiyuan's chopsticks to pick up a mouthful of rice for him: "This is a reward for you, ah~"

Watching Pang Zaiyuan swallowing the rice, Ning Wenru couldn't help but laugh. His Zaiyuan is so cute when he wants to be intimate! So you and I feed each other a mouthful of rice, which is particularly disgusting. After dinner, Pang Zaiyuan made Ning Wenru put down his mobile phone completely and the idea of ​​continuing to type, and devote himself wholeheartedly to the wonderful sport of hey boyfriend!

After the exercise, the two took a shower in the bathroom and started packing their luggage for home. As Pang Zaiyuan packed, he said, "Let's continue to take leave. Say you're going home for the New Year, and Da Mumu will take a month off."

Ning Wenru said, "No, I have to write when I'm not visiting relatives during the New Year. After all, after school starts, I may have to intern at the captain's company, and then I'll be busy again. It's a long way to go before I can finish. By the way, why didn't Lele come back so late today? The library must have closed a long time ago."

The phone suddenly rang, and the sound of "Red envelopes are coming~" cheered up the dormitory! Ning Wenru opened WeChat and found that Le Weijian had sent him two big red envelopes! The amount just matched the amount that Pang Zaiyuan and Ning Wenru had sent to Le Weijian last time.

There was also a voice message: "Hahaha! Thank you Ningning for rushing me to the library. A junior girl from the Foreign Language Department confessed to me and said that she liked the way I read books very seriously. She also said that it is rare to find a sports student who spends every day in the library studying! The junior girl is very cute. We are together! My peach blossom luck is coming! I don’t have to be abused by you guys anymore! I won’t go back to the dormitory tonight. The junior girl and I will go to the movies. Then you know what to do. You don’t have to leave the door open for me. You can lock it as you like! Here are two red envelopes for you. Thank you Ningning for rushing me to the library. I also gave you Yuange’s red envelope. Anyway, you are together. His red envelope is too big and I don’t feel comfortable taking it. That’s it. I wish you all good luck and a long-lasting relationship!"

Ning Wenru replied "Congratulations" and typed back: "You have to take good care of your junior schoolmate this time you are in a relationship, learn from your last lesson. What does your new girlfriend look like? Do you have a photo?"

Le Weijian posted a photo of him and his junior schoolmate drinking milk tea together. The junior schoolmate had a very student-like temperament. She was not dressed up much. Her long hair was simply tied into a ponytail. She wore glasses and looked quite quiet. She was not the same type as his ex-girlfriend Xiao Xin, who was beautiful, pretty and capable.

After a while, Le Weijian replied with a text message: "Next year she will be a senior in college, I will take care of her like a man. She is very ambitious, her ex-boyfriend is a librarian, she had a love affair with the library every day, she is obsessed with pure English books and can recite English poems. I have to work harder and learn English well, otherwise we won't even have a common language, I can only say "fuck", and I will be abandoned again in the future."

Ning Wenru was particularly pleased to see the message from Le Weijian, and was happy for Le Weijian's growth. The best love is when two people make progress together.

Pang Zaiyuan was particularly moved after hearing this and said, "I am not very good at my major and I am also worried that you will leave me behind."

It turns out that even though Pang Zaiyuan is in such good condition, he still has things to worry about! Ning Wenru said, "Me too, my belly has just shrunk, my abdominal muscles are no longer eight-pack, my chest muscles are very flat, my arms are thinner than yours, and my muscles are smaller than yours. I feel that there is a big gap between us."

Pang Zaiyuan smiled and said, "It's okay, you're good, just look at my figure. It doesn't matter if Mumu is small, as long as the technique is good."

"Techniques must be supported by abdominal muscles!" Ning Wenru said, "But I don't care whether I am strong or not. My muscles don't have to be stronger than yours. I just want to train with you to have a healthy body and stay together for a long time."

"Okay, I'll urge you every day." Pang Zaiyuan was very moved. He put down his luggage, hugged Ning Wenru and kissed him again and again, and said, "Tomorrow we have to report on the single-chip microcomputer works. I'll be the one who reports. Do you have time to come and listen? But the works are very simple for you."

Ning Wenru said, "Since you have invited me, I will definitely go."

…

Microcontroller works summary course.

This time, all the mechanical and electrical classes attended the report class together. There were 15 groups in the three mechanical and electrical classes, and more than 140 people gathered in a large classroom. In addition to Pang Zaiyuan, the only person Ning Wenru was more familiar with in the mechanical and electrical class was his teammate C, so he sat between teammate C and Pang Zaiyuan.

Teammate C's group created a palm-sized car that can scoop up garbage and automatically avoid obstacles and pits. Before presenting it to the teacher, Teammate C demonstrated it to Ning Wenru in advance and said, "I looked at the works of other groups, and not many of them succeeded. Our group's will easily win first place! What about yours?"

Pang Zaiyuan said: "I succeeded in doing it, but I think I am the best."

"You are so awesome," Teammate C challenged, "Can you beat me? Show us what you have made."

Pang Zaiyuan retorted: "It's not for you to see. You can read the report later."

Teammate C asked Ning Wenru unwillingly, "Are you playing a trick on your boyfriend? Tell me, teammate, between you and your boyfriend, who do you support to win first place?"

Ning Wenru said very objectively: "I really have never seen my family's works, nor have I intervened. I just gave guidance in looking up information. Who can take first place, of course, will have to see other works first."

Because we only had about a month to make the work, the time was quite tight. Although we only selected ready-made chips to make the work, only 9 out of 15 groups were able to successfully make the finished product and realize the functions. Two groups only drew the circuit diagram, and the program compilation failed, and they could only realize a small part of the functions, and they didn't have time to make the finished product; three groups only compiled the program and circuit diagram, but the finished product failed. For example, the transistor of the perpetual calendar displayed garbled codes; another group encountered an accident when running the finished product, and burned the chip.

The remaining 9 successful ones all did well. For example, the calculator can do addition and subtraction, and can also display fractions. The perpetual calendar takes into account the Chinese zodiac and leap years, and also has an alarm function. Teammate C's work is also very successful. He is the only team that made a car.

Pang Zaiyuan's group was the last to demonstrate. Pang Zaiyuan came on stage with a work wrapped in dark blue brocade cloth, about as long as his arm. He gently placed the work on the podium, and then, under the curious gaze of teachers and students, he lifted the brocade cloth.

The work under the brocade cloth was very simple, without an outer shell. The arm-long work held up pieces of green circuit boards, blocking the line of sight. Ning Wenru could not tell what it was for a moment.

"Our group's work is an electronic keyboard," Pang Zaiyuan said. "Due to time constraints, we only made 22 keys. Before introducing the work, I will play a song for my partner, "Love for You."

As soon as Pang Zaiyuan said he would play the electronic keyboard for everyone, the students in the three classes who were still in heated discussions gradually quieted down. The few remaining girls in the mechanical and electrical class even turned on the recording and looked forward to it. Ning Wenru's mind was also attracted, and he walked directly to the edge of the classroom and turned on the video.

Students from three classes were watching. Pang Zaiyuan was very generous and not shy at all. He put his fingers on the keys to play the accompaniment. While looking at Ning Wenru's position, he sang in a low and soft voice: "I am in love with you and I am sincere to you. Please treasure this love..."

It was the first time Ning Wenru heard Pang Zaiyuan sing. His magnetic voice was intoxicating, needless to say. The magnetic bass and the sound of the keys complemented each other, deep and gentle, like the ripples of the lake in the spring breeze, blending well together.

What made Ning Wenru even more intoxicated was that Pang Zaiyuan was singing a love song! He was singing a love song to him in front of his teachers and classmates!

There were only a few girls in the mechanical and electrical class. They looked at each other curiously, and then followed Pang Zaiyuan's gaze to find out who Pang Zaiyuan was singing love songs to in public! The boys sighed and said in a low voice: "It's a good thing that Brother Yuan didn't participate in the campus top ten singers competition. If he had participated in this competition, we would have been dead!"

Teammate C, who knew the truth, covered his mouth and laughed, looking at Ning Wenru with a teasing and envious look, but Ning Wenru didn't look at him at all, immersed in Pang Zaiyuan's beautiful singing.

Pang Zaiyuan sang half of "Loving You", and in order to show their group's work, they played half of the sonorous "Song of Strict Discipline" and half of the Happy Birthday song. After the three songs were demonstrated, Pang Zaiyuan introduced the group's work: "The inspiration for making the electronic keyboard came from my partner. He said that he was in the mechanical and electrical class, and the electronic keyboard and love billboards could be used as gifts for girlfriends. He also said that it was very simple to make. When I actually made it, I found that it was not simple at all. Here is the division of labor and time arrangement among our teammates..."

Ning Wenru listened and sneaked back to his seat. As soon as he sat down, teammate C punched him lightly and said in a low voice: "You guys are really good. You even showed your affection in front of the classmates and teachers of the third class of mechanical and electrical engineering!"

Pang Zaiyuan's report continued: "Determining the piano sound is not as simple as imagined. It is difficult to find professional knowledge on the Internet. We can only adjust the frequency of the buzzer little by little, and determine the pitch of the piano sound by constantly modifying the program..."

Ning Wenru ignored his teammate C, holding his face with his hands, looking like a fanboy, fascinated by Pang Zaiyuan's serious report. It turned out that his Zaiyuan had made such serious preparations to sing a love song for him in public, and he must reward him well when he returns!

Although this electronic keyboard was not packaged, the circuit board was exposed and there were traces of solder scraped off, which showed that it had been modified many times. Although it was simple, the love hidden in the electronic keyboard was very deep. Ning Wenru could feel the dedication of Pang Zaiyuan and the efforts of Pang Zaiyuan's team members.

After Pang Zaiyuan finished his report, the microcontroller teacher was very happy and felt a sense of accomplishment. After asking about the cost of the electronic keyboard, he took out double the money on the spot and wanted to buy this simple electronic keyboard without packaging to show off to the next class of students. Pang Zaiyuan agreed to sell the work to the teacher only after asking for the opinions of his team members and Ning Wenru.

When it was time to announce the scores, the work of Pang Zaiyuan's group and teammate C both received full marks. But it was clear that the teacher preferred the electronic keyboard. After the report class was over, the students were talking about Pang Zaiyuan's work. Some came to ask Pang Zaiyuan's team members for advice, and some came to gossip: "Do you know who Pang's girlfriend is? They sang love songs in public, so his girlfriend must be there! But there are less than ten girls in the mechanical and electrical class, and none of them look like the girl by elimination."

"Yes, the three girls in his class all have boyfriends. They are from different classes, so we don't usually see them walking together. Instead, we see Pang and his roommate walking together more often."

"Yes, I see them doing morning exercises together and going to the library together every day, so they must have a good relationship. Why not ask his roommate, ask Pang who his girlfriend is? His roommate will definitely know."

Ning Wenru smiled but said nothing after hearing this. What was he waiting for after school? Of course he had to reward Pang Zaiyuan and have a deeper emotional exchange with him!
