Chapter 417 What's the point of asking for leave if there's no leave slip?

Chapter 417 What's the point of asking for leave if there's no leave slip?
However, out of politeness,

She still smiled and said, "Chen Luyang, when you really become the minister, don't forget about our Literature and Art Department!"

"If you ever need someone to fill in for a gala performance in the future, remember to come back and give me some advice!"

"No problem! If you call me, I'll be there right away!"

……

After registering for the student council,
Chen Luyang arrived at the Science Building with her schoolbag on her back.

The afternoon sun slanted into the door of the Mechanics Department's administration office, where the "Course Schedule for This Semester" was posted.

Chen Luyang took out a used homework sheet from his pocket, flipped it over, and squinted at the table while comparing the mechanics department's timetable with the economics department's course schedule.

Although he had already made up his mind to ask a professor in the mechanics department for help in drawing industrial blueprints,
But finding a reliable teacher, someone with strong skills, and someone willing to cooperate—all of this has to be done by observing classes and listening in on students' conversations.

"Monday won't work. I have advanced mathematics in the morning and a major course in the afternoon."

"Tuesday... won't work either, it's available all day."

"Wednesday...also a conflict."

Thursday... damn it!

The economics department has no classes, and so do they!
A round of comparisons
Chen Luyang's brows furrowed more and more tightly.

The first-year courses in the economics department are already full, leaving little free time.

He thought he could sneak in some free time to attend classes, but he didn't expect that the mechanics department's schedule would clash with theirs so badly.

Just as Chen Luyang was struggling with which class to attend, two students walked over.

Chen Luyang quickly stopped the person and politely asked, "Excuse me, could you tell me which of these courses is the best? I'd like to audit some classes and learn from them."

Which course is good? They're all good. What's your major?

"I'm in the economics department."

"Economics Department?" The student paused, a little confused. "Can you understand me?"

"It should be possible...?"

"Professor Li Xiping's lectures on mechanics of materials are quite interesting; you should check them out."

Mechanics of Materials…

Chen Luyang quickly wrote the words "Li Xiping Materials Mechanics" on the notebook.

"Thank you, classmate."

"fine!"

……

Unlike the lively and spectacular scene in the philosophy department, where students stood and listened to lectures.

The mechanics department classrooms were quite deserted.

The classroom was sparsely populated, with at most ten or so students seated. The first few rows were a bit crowded, while the back rows were mostly empty.

As soon as Chen Luyang entered the classroom, she attracted a lot of attention.

He braced himself and pretended to be calm as he walked to the last row of the classroom and sat down, several rows away from the students in the mechanics department, making him stand out conspicuously.

Just as I settled in, a surprised voice rang out:

"Chen Luyang? What brings you here?"

"Senior??"

Chen Luyang stared wide-eyed at the girls in the Literature and Art Department.

"Are you in the mechanics department?"

"I thought you were a liberal arts student!"

The girls in the arts and literature department laughed: "Just because I have a knack for the arts doesn't mean I study literature!"

Chen Luyang was speechless.

Good guy...

If he had known this senior was in the mechanics department, he would have just asked her directly.

Why bother asking someone to copy a form by yourself?
Before I could think about it, a middle-aged male teacher walked into the classroom carrying a thick textbook.

"Let's start the class."

He placed the book on the podium, glanced around the classroom, and his gaze quickly settled on the last row.

"Oh, a new face! I've never audited this class before."

Chen Luyang immediately stood up: "Hello teacher, my name is Chen Luyang, and I am from Class 1 of the Economics Department."

"Economics Department?"

Li Xiping asked with a look of curiosity, "Why would someone from the Economics Department want to attend a Mechanics Department class?"

Chen Luyang looked slightly embarrassed: "I heard that the teacher is good at teaching, so I wanted to come and broaden my horizons."

“Okay.” Li Xiping said happily, “Then I’d better give a good talk today, so I don’t scare people away again.”

In the relaxed classroom atmosphere, Li Xiping opened his book and said in a light tone:

"Today we continue our discussion on 'the control of the plasticity and strength of materials'."

"When metals enter a plastic state at high temperatures, if the hammering frequency is too high, localized overstress zones will form, reducing ductility..."

As he spoke, he wrote several terms such as "Δσ, ε, τ critical" on the blackboard.

Chen Luyang watched as the students in the classroom took out their textbooks and notebooks and began taking notes.

He also took out his notebook and pretended to copy the blackboard notes.

to be frank,
As someone who can't even understand advanced mathematics... well, I'm just a little idiot.

He is extremely self-aware.

With his limited scientific knowledge and scientific thinking, he absolutely could not understand the mechanics of materials.

But as Chen Luyang listened, she sensed something was wrong...

The teacher was talking about "the plastic zone of a material after heating", "the control point of stress release", and "critical fracture stress"...

How come it's exactly the same as the forging, prototyping, and strength testing process his father, Chen Dazhi, used to do in the forging workshop?

Isn't this exactly the scene of his father hammering forging billets in the workshop?
After Li Xiping finished speaking, he flipped through his textbook, then suddenly stood up straight and scanned the whole class.

"Then let me ask you a question."

He leaned back on the podium, scanning the entire room. "If the steel parts repeatedly crack during the forging process, even if the temperature is normal and the hammerhead is fine, then what stage is most likely to have a problem?"

The most anticipated part, the Q&A session, has finally arrived.
Just as Li Xiping was about to call roll, his gaze shifted and he saw a particularly "eye-catching" auditor in the last row.

His eyes lit up, as if he had discovered some little treasure, and a grin spread across his face.
“The student who was auditing the class, you tell us.”

"Me?" Chen Luyang was taken aback and pointed to herself.

“Yes.” Li Xiping’s eyes held a childlike amusement. “It’s rare for someone to come and audit my class, so we should treat them with great hospitality.”

As soon as he said that, the whole class laughed.

Chen Luyang scratched his head and stood up hesitantly.

He hesitated for two seconds, recalled Chen Dazhi's usual work in the workshop, and tried to speak:

"Perhaps... the metal's trajectory wasn't controlled?"

Li Xiping raised an eyebrow: "Oh? Continue?"

Seeing that the teacher didn't refute him, Chen Luyang became bolder and gestured with his hands as he said:
“If you don’t care about the direction of the metal fibers during forging and just hammer them directly, the forged material will break into many short fibers inside. Although the surface of the forged part is smooth, the internal structure will have long been broken into pieces. On the contrary, if you follow the direction of the metal itself, like pulling it apart one piece by one with each hammer blow, it will become particularly strong and the internal structure will be more stable.”

Chen Luyang tried to explain the practices of the forging workshop workers:

"Another possibility is that the temperature is not high enough..."

"It's not that the temperature is insufficient, it's that the core of the embryo hasn't been heated through. The furnace temperature is high enough, but the core temperature hasn't risen. Although the surface is hot, the core in the middle is still cold, and it will explode when you hit it."

Li Xiping blinked, seemingly surprised that this little observer had answered the question using such a production method. "Your explanation is quite interesting. Have you been to the workshop before?"

Chen Luyang said modestly, "My dad is a factory worker, and I often watch the factory workers work."

"Tsk..." Li Xiping couldn't help but sigh softly, "I was wondering why you came to listen to the lecture. You know quite a lot. Have a seat."

"Thank you, teacher."

call.

Chen Luyang let out a soft breath.

Luckily, his father was the director of the forging workshop, and he had been exposed to the industry since childhood. He answered Li Xiping's question with a mix of guesswork and deduction.

Otherwise, if he stood up, he would look like a complete idiot and wouldn't be able to answer anything.

That would be embarrassing.

But you know what, this class was definitely worth it.

For example, as Li Xiping said, "When a material is struck before it has reached a fully plastic state, microcracks will form, which will continue to expand during use and eventually break."

This reminded Chen Luyang of a failed batch of half-shafts produced at the forging station a few years ago.

When Old Chen came home that night, he was still annoyed that "the feed was moving too slowly, the core was still hard, and I was too hasty in striking it."

At the time, he didn't think much of it after hearing it.
Looking back now, it's no wonder that the shaft in Old Chen's workshop broke!

Although he didn't understand many of the things and technical terms.

But once it came to actual production, Chen Luyang had a sudden realization, as if a lightbulb had gone off in his head, and he understood everything all at once.

Looking down at the densely packed page of notes I had taken,
Chen Luyang felt like she had really hit the jackpot!
If I were to take these little notes home and show them to Old Chen, who knows what kind of qualitative leap Old Chen's skills might make!

……

As the bell rang to signal the end of get out of class.

The sound of chairs being dragged echoed through the classroom, and students began to pack up their books and leave in twos and threes.

A senior from the Arts and Literature Department walked over from the front row and curiously asked:

"Chen Luyang, what made you decide to attend a class in our Mechanics Department?"

Chen Luyang said mysteriously, "Senior, actually I'm here to do some research."

"A survey?" The senior student was taken aback. "A survey about what?"

Chen Luyang said, "I want to ask the teachers and students in our mechanics department to help me draw some industrial drawings, but I don't know who to ask. So I thought I'd try my luck in class and see if I could meet some teachers and students who are good at drawing."

The senior from the Arts and Literature Department asked in confusion, "What kind of blueprints do you want to draw?"

Chen Luyang said, "Spark plug, nozzle tube, and rubber gasket."

The senior from the arts department was puzzled: "Why are you drawing these things if you have nothing to do?"

When Chen Luyang recounted the story of the car maintenance and repair center, the senior students from the Literature and Art Department widened their eyes in astonishment.

"You're in charge of repair shops? Really?"

"real."

Chen Luyang nodded seriously, "We've almost finished collecting the basic data, all we need are the blueprints. Senior, do you know any students or teachers who are good at drawing? Could you recommend someone?"

The senior from the Arts and Literature Department thought for a moment and said seriously, "If you want to draw blueprints, the Materials Science course probably won't be of much help."

"Materials Science focuses more on the mechanical properties, heat treatment characteristics, fracture and fatigue of metals, mainly to help you understand whether a material is usable."

"The ones who are truly good at drawing are the teachers of 'Mechanical Drawing,' 'Fundamentals of Mechanical Design,' or 'Principles of Machinery,' which are the major courses for third-year students. They draw every day and their drawings are clearer than those in print."

"If you can strike up a conversation with the teachers of these three subjects, they can draw the blueprints much faster and more professionally than you can figure it out on your own."

Chen Luyang's eyes immediately lit up: "Do you know who those teachers are?"

"Yes, I know." The senior student nodded.

"One is Teacher Zhang Diancai. He used to work in the Seventh Ministry of Machinery Industry. I heard he specializes in drawing military parts. He draws blueprints quickly and accurately, and he can distinguish between standard and non-standard parts very clearly. It's just that he's a bit... stubborn. He does things in a very meticulous and particular way."

"There's also Teacher Lü, who was a student of Teacher Zhang and is now teaching classes. Although she's a bit young, her skills are really strong."

"They all sound amazing!" Chen Luyang rubbed her hands together excitedly. "Where do they work?"

"Teacher Zhang is in office 212 on the second floor of the west side of the Science Building. Teacher Lü is opposite him in office 215."

The senior student thought for a moment and added, "But you'd better not expect to be able to catch anyone as soon as you go."

"What's wrong?"

"They are both extremely busy."

A senior student from the Literature and Art Department explained, "Professor Zhang is currently working on projects with military research institutes, mechanical research institutes, and weapons design institutes at the same time. He's either in the factory or at the research institute during the day."

"Professor Lü is also always out participating in projects, and you can hardly see him all day. He is rarely in the office except during class time."

Chen Luyang nodded, not intimidated at all; instead, her eyes lit up.

Being able to work on projects with these organizations means their technical skills are absolutely top-notch.

You can't go wrong with getting him to draw the diagrams.

"Senior, today's class was so worthwhile!"

Chen Luyang expressed her heartfelt gratitude, saying, "You even found out the way for me, thank you so much!"

"Don't thank me too soon," the senior from the Literature and Art Department said with a smile. "Whether they agree to draw it is still uncertain. If you really go to them, remember to be polite."

"Understood!" Chen Luyang grinned.

……

With her senior's advice, Chen Luyang is finally not completely blind anymore.

Dormitory 421 at night.

Chen Luyang sat at the table and took out the mechanics department's timetable that he had copied down, wanting to see which day of the week "Principles of Machinery" was taught.

This is quite interesting...

wipe!
All of the "Principles of Machinery" courses conflict with my major courses!
Chen Luyang frowned!
What the hell am I going to do...?

He repeatedly compared the two timetables, biting his pen and scribbling left and right.

Last but not least!!!

"...It seems we have no choice but to sacrifice him!"

Chen Luyang frowned deeply as she compared the course schedules for her major with those for the mechanics department!
Without much hesitation, they directly selected the course they were going to sacrifice.

……

The next day

"...Where's that boy who's always nodding and fidgeting? Why isn't he here?"

As soon as the school bell rang,
The advanced mathematics teacher scanned the classroom, frowned, and asked a question.

"Teacher, he asked for leave today."

Tao Runze stood up and asked for leave for Chen Luyang.

"You asked for leave?" The calculus teacher frowned!
"What kind of leave did you request? Who did you ask for it from? Where is the leave slip?"

"I don't have a leave slip," Tao Runze replied, forcing a smile.

"...He just had an upset stomach."

"Not having a leave slip doesn't count as requesting leave! That's called skipping class!"

The calculus teacher's lips curled down, his voice carrying a murderous intent.

"If you don't understand the lesson and still don't come to listen, then you'll understand it even less!"
