Lao Liu's control of time is still so accurate, he came at eight o'clock, and at seven fifty-nine, his figure appeared at the staircase on time, holding a black briefcase, looking like a dusty servant.

Lao Liu saw me standing at the door, and asked with a little confusion: "Come, the door is open, why don't you go in and wait?"

When he got closer, I saw Lao Liu's bloodshot eyes, his face was a little haggard, and at a glance, I knew that he didn't have much rest last night, but his straight posture made him have a different temperament at this moment.

"Ah...... Teacher, I just arrived. "

"Come, come in, you draw your own first, and you can ask me at any time if you have any questions. Lao Liu had already pushed the door open as he spoke.

I poked my head in with my laptop and looked at it with some curiosity, even though I had been to this office many times, I always felt a little uncomfortable each time. Moreover, Lao Liu shared an office with another teacher, but I didn't see where the other teacher was.

Lao Liu seemed to see my embarrassment, pointed to the empty position and said, "You sit there, Teacher Yang is on a business trip, don't be so restrained." "

I nodded slightly, moved the computer to the desk, put it away, and began today's penance.

At first, I would look at Lao Liu from time to time, but later I found that he was busy on the computer all the time and did not keep staring at me as I imagined. Also, it's just talking, how can you really stare at me all the time. I finally relaxed, rubbed my hair, let go of my hands and feet, and began to dry.

......

Time passed minute by minute, and the whole structure diagram has been perfected, except for some small details that need to be further investigated, I feel a little bored looking at the marked numbers. Although there is nothing wrong with the size and structure, this picture gives a really bad impression, and the annotation is too arbitrary, so that people don't have the desire to look at it at all.

My attention kept switching back and forth between the computer screen and the manual in my hand, until I felt that my eyes were a little sore, and I leaned back in the chair and stretched, and I found Lao Liu standing next to me.

Suddenly, a spirit quickly stood up and said, "Teacher, are you ...... How do you ......" was speechless for a moment, and I didn't know what to say. Lao Liu didn't say anything, just pressed me back into the chair, and focused his eyes on my structural diagram again.

"Well, it's pretty good in general. But your annotation is too messy, it doesn't seem that the whole picture is too beautiful, do you want to consider using polar coordinates to try, at that time to give you a lecture due to time reasons, these places are all brought in a word, I think many students have forgotten this. "

Lao Liu's faint words were like an initiation, and instantly made me understand where my awkward feeling came from. I cast a grateful look at him and said, "Understood, thank you, teacher." "

Rubbing my sour eyes, I was about to continue drying, but I was stopped by Lao Liu, and I looked at him with a little doubt.

"Are you stupid to draw?" Lao Liu said with an angry look at me.

Lao Liu's words made me even more confused, and I looked at him with a puzzled expression.

"Alas. Lao Liu sighed lightly and said, "Let's go, eat first, and come back after eating." "

Hearing Lao Liu's words, if I didn't react, I would be really stupid, and glanced at the time at the bottom right of the computer screen, it turned out that it was already twelve o'clock.

There are two things that Lao Liu looks at the most, one is the student's learning problem, because he has never been angry with learning, which is also the main reason why we are timid about him, and the other is the problem of eating, in his opinion, only by eating first can he have the strength to study, which has almost become a life philosophy that Lao Liu followed.

Lao Liu had already taken the lead in walking out of the door, and I hurriedly tidied up the table briefly, and followed behind him.

......

Familiar restaurants, familiar dishes, familiar porridge, and of course, the serious and somewhat confused face in front of you. It is really rare for Lao Liu to have such an expression, could it be that people like Lao Liu will also have troubles? The more I thought about it, the more curious I became, I couldn't eat at ease, so I picked up my cup and pretended to drink water, and my eyes glanced at Lao Liu from time to time.

"Look at what? Is there something on my face?"

Lao Liu's sudden question caught me off guard, and I couldn't help but squirt out of the sip of water that I just drank in my mouth, but fortunately there was no one in the aisle next to me, and I was secretly glad that I slowly raised my head at the same time and glanced at Lao Liu.

With a hint of concern on his face, Lao Liu handed me a tissue, and I hurriedly reached out to take it, and said embarrassedly, "Thank you, teacher." "

"Eat well, don't think about messy things. "

I nodded yes again and again, and his wise eyes seemed to be able to see what I was thinking, and I felt that in front of him, anyone would have nothing to hide.

......

"Wuxiu, are you students afraid of me?"

Even with my previous experience, I still squirted, but this time I wasn't so lucky, and I happened to spray it on a male classmate passing by, and it looked familiar, as if it was from our college. I took a tissue and wiped it for him, apologizing incessantly. He was quite angry at first, but when he saw Lao Liu behind me, his face instantly turned cloudy and clear, and he said hello to Lao Liu and slipped away in a hurry.

Hearing his familiar, distressing greeting, I was sure that he was from our hospital.

Lao Liu looked at the back of the classmate who was far away, fell into deep thought, and asked a little blankly for a long time: "I...... Is it really that scary?"

I don't know why, when I saw Lao Liu's appearance, my first reaction was that I thought this old man was also cute.

I carefully recalled everything about Lao Liu in my memory, except for hearsay, it seems that I really haven't seen how harsh Lao Liu is, just this morning, I sat in an office with him all morning, and I didn't feel any pressure, and that sense of restraint was completely imposed on me by myself.

Did we have any misunderstanding about Lao Liu? Just as I was thinking like this, Lao Liu's question floated over again: "Hey, Yun Wuxiu, what is the reason for that? Every student hides away when they see me, and I am not the kind of person who is particularly fierce-looking." "

I replied a little timidly, "Maybe...... They think you're a little shocked. "When I said this, I kept my head down, and I didn't dare to look at Lao Liu's face at all.

But who would have thought that Lao Liu would not be angry at all when he heard my words, but his tone revealed a trace of grievance, and said: "It's no problem, after all, this voice is innate, and it can't be changed." "

I kept thinking about the reason why Lao Liu would have this kind of problem, and a thought slowly came to my mind, he is our department head and also a teacher, he is majestic when he is the head of the department, because he must have the courage to deter all students and teachers, and when he is a teacher, he only thinks about how to have a good relationship with his classmates, how to make us know more knowledge.

Unfortunately, most students only remember his might as head of the department, and his hard work as a teacher was completely overshadowed by the power of his head of the department. After all, compared to a good reputation, the spread efficiency of a murderous reputation is still a little stronger.

......

After a break at noon, I followed Lao Liu back to the office to do penance, Lao Liu this time was the same as I imagined the operation, and I have been watching from the side since I started drawing. But he didn't make a sound, just sat quietly on the sidelines.

I don't know if the conversation with Lao Liu at noon made my impression of him change a little, but now not only do I not feel any discomfort, but I really expect him to point out my mistakes. Before that, I couldn't even think of this kind of thing, and just sitting next to me made me so nervous that I couldn't speak.

......

"Teacher, I don't think this place can be fully represented if it is dissected in a conventional three-dimensional view. "I was puzzled for a long time, and I finally couldn't help but ask, hoping that Lao Liu could solve my doubts.

"You do what you feel, don't stick to tradition, you can express it clearly as you think, you can draw it. Those of us who are teachers wish that there would be some of our alternative things on your drawings, and that innovation is possible only when there is change, and that everything that is the same can only be regarded as copying. "

Lao Liu's reply was a little unanswered, but he gave me a new understanding of my major, I nodded slightly, and began to bury my head in the operation again, the keyboard and mouse were crackled by my press.

......

I don't know how long it took, there was a faint snoring in my ears, and I turned my head slightly, and found that Lao Liu had fallen asleep, and his nose twitched a few times from time to time. The air conditioner in the room was still on, I stood up gently, put my coat on Lao Liu, and looked at his sleeping face, I really realized that he was really just a very ordinary old man, and he was not as fierce as rumored.

As for the rumor that Lao Liu pressed a student in the office and reprimanded him for three hours, I am also a little skeptical about it now, is such Lao Liu the one who can do that?

"Uh-huh........."

The sudden sound startled me, I thought Lao Liu was awake, and subconsciously looked at him, but I only saw his mouth move slightly...... At this time, Lao Liu felt more like a child, especially the mouth that was not a few chirps.

I had a bold idea to use my mobile phone to take a picture of Lao Liu's appearance. If I had this picture in my hand, I think I could blow it in front of the big ones for the rest of my life.

Just do it, take out your phone and get ready for action. Unexpectedly, as soon as the phone was taken out, it rang, and in order to avoid delaying the fighter, I hung up the phone as quickly as possible.

I just turned on the camera and was about to take a picture, but I found that Lao Liu had opened his eyes, and I was suddenly timid, but thinking about the bragging capital of my life, I still took a picture.

Lao Liu didn't seem to notice what I had just done, he just stood up slowly, and when he saw the coat I put on him, his face was obviously stunned, paused, and asked, "What time is it?"

I glanced at my phone and replied, "It's half past five." "

After Lao Liu tidied up his clothes, he said: "It's almost, let's do it today, go back, and come back tomorrow." "

I nodded slightly, and saved the day's results. When he was about to clean up the room and leave, Lao Liu pointed to the door and urged: "Don't waste time, the little girl has been waiting for you at the door for a long time, and the sanitation will be cleaned early tomorrow." "

"Little girl?" I looked towards the door with a hint of doubt, and saw Nie Xinyan's pretty face.

The sudden surprise made me feel embarrassed, and after giving Lao Liu a bear hug, I rushed out......
