Reborn in 1977, I will no longer be my brother's blood bag.

Outside the conference room, the air was somewhat quiet.

A middle-aged man in cadre uniform was talking to the institute leader—he was in his forties, had a square face, a serious expression, and a pen in his breast pocket; he looked like someone from a research institute.

Meanwhile, inside the room, Professor Chen had already opened the documents:

"Let's put the competition aside for now."

Li Mingyuan and the others looked up at the same time.

The competition is on hold? Then what's the point of today's meeting?

Professor Chen didn't explain, but simply looked towards the door and said, "Come in."

The next second, the conference room door was pushed open, and the middle-aged man walked in.

Several students instinctively sat up straight. The aura emanating from the other person was clearly different from that of a school teacher; it was more like someone genuinely involved in a national project.

Professor Chen put down his teacup and gave a brief introduction: "Director Qin from the Mechanical Engineering Research Institute."

As soon as he finished speaking, Li Mingyuan and Zhao Guodong's expressions changed simultaneously.

Mechanical Research Institute.

In this era, it was practically a top-tier unit.

Many graduates are desperate to get in.

And now, the people from the research institute have actually come on their own initiative.

Director Qin's gaze swept over everyone, without any pleasantries or formalities; his first words were:

Who is Lin Xiuhe?

All eyes turned to them at the same time.

Lin Xiuhe stood up: "Yes, that's me."

Director Qin looked at her for a few seconds, his brows furrowing slightly.

Too young, much younger than I imagined.

He had initially assumed that the person who discovered the vulnerability would be at least a senior student, or even a graduate student. It turned out to be just a freshman.

"Is this the problem you discovered?"

"Yes."

Why did you think of that place?

Everyone is waiting for an answer.

Lin Xiuhe remained silent for a moment.

She couldn't very well say that she had seen a similar system in her past life. So she had to find another way to put it:

"Because it's unreasonable."

"What's unreasonable about it?"

"Growth curve".

She picked up a pen and drew two lines on the paper, one gentle and one steep, then explained:

"Currently, production capacity is low, so the problem isn't apparent. But once production expands, the error will be amplified."

The sound was not fast, but very clear.

The meeting room gradually quieted down, and even Director Qin became serious.

A few minutes later, he put down the documents and didn't ask any more questions. Because that was enough.

The layman sees the spectacle, the expert sees the details. Those few words just now are enough to prove a lot.

Thinking of this, he looked at Professor Chen with a complicated expression: "Old Chen, you're lucky."

Professor Chen immediately laughed: "Do you believe me now?"

Director Qin remained silent, which was taken as tacit agreement.

Just then, the college leader walked in: "Professor Chen, the open class is about to begin."

Professor Chen nodded, then looked at everyone and said, "Let's go, it's a good opportunity to let Director Qin listen in as well."

Everyone was stunned. A public lecture? Wasn't it supposed to be a meeting?

Ten minutes later, in the large lecture hall.

The classroom was already full of students—from the Automation, Mechanical Engineering, and Electrical Engineering departments—and even quite a few teachers. There were over two hundred people in the classroom, and the atmosphere was lively.

As everyone knows, Professor Chen rarely gives public lectures, and every time he does, people come specifically to listen.

In the last row, Director Qin sat down, his gaze still fixed on Lin Xiuhe, clearly still observing her.

On the platform, Professor Chen picked up the chalk, but instead of lecturing, he wrote a problem on the blackboard.

Soon, half the blackboard was filled with writing.

The classroom gradually quieted down, and then became even quieter.

Because everyone realized: they couldn't understand it. They couldn't understand it at all.

Several teachers in the first row began to frown, not to mention the students.

Li Mingyuan stared at the blackboard, his brow gradually furrowing, as did Zhao Guodong. The entire classroom was silent.

five minutes.

ten minutes.

No one spoke.

Professor Chen turned around, his gaze sweeping across the room: "Does anyone have an idea?"

No one raised their hands.

The atmosphere became increasingly awkward because no one really knew how to do it.

Director Qin, sitting in the back row, couldn't help but laugh: "Old Chen is still the same as ever, always making things difficult for students."

The teacher next to him smiled wryly: "Even graduate students might not be able to solve this problem."

On the podium, Professor Chen remained unhurried and waited patiently.

After a while, suddenly, a voice came from the back of the classroom:

"teacher."

The classroom fell silent as everyone turned around at the same time.

Lin Xiuhe stood up.

Instantly, countless eyes turned to her. Some were surprised, some were doubtful, and some thought she was crazy—after all, even the teacher hadn't said anything, yet she had actually stood up?

A hint of a smile flashed in Professor Chen's eyes: "Tell me about it."

Lin Xiuhe looked at the blackboard and slowly said, "I don't know."

boom--

The classroom nearly erupted in chaos.

No? If you don't know, why are you standing up?

Even Li Mingyuan was taken aback.

However, the next second, Lin Xiuhe continued, "But I think this question might be wrong."

The air froze instantly.

Director Qin sat up abruptly, while Professor Chen's smile grew wider and wider.

Everyone in the classroom was stunned.

The question is wrong? What do you mean? This question was set by Professor Chen!

Lin Xiuhe had already stepped onto the podium, picked up the chalk, and drawn another derivation route next to the original problem:

"If the goal is to control efficiency, this parameter is meaningless. What you should really look at is this."

As the chalk fell, the classroom grew quieter and quieter.

At first, some people had doubts, but as the deduction unfolded, many teachers' expressions gradually changed.

Because she's right. This question doesn't really test your calculation skills, but rather your thought process—whether you can question the question itself.

Ten minutes later, Lin Xiuhe put down the chalk.

The classroom was completely silent; you could hear a pin drop.

In the last row, Director Qin slowly stood up, his eyes changing completely for the first time.

He finally understood why Professor Chen had called personally and why he had said, "I've found the person."

The scariest thing about this girl is not that she can solve problems, but that she dares to question them.

Just then, Professor Chen suddenly smiled and looked at the entire audience, uttering a sentence that everyone would remember for many years:

"Knowledge is not just about answering questions, but more importantly, about discovering questions."

As soon as he finished speaking, the entire classroom fell into a deathly silence.

Director Qin had already turned to look at the college leaders, his voice low but unusually serious: "Is she really a freshman?"

The college leader nodded with a wry smile: "They just enrolled."

Director Qin was silent for a few seconds, then looked at Professor Chen: "Old Chen, our institute is short of someone recently."

Professor Chen picked up his teacup and smiled like an old fox: "What a coincidence, I was just about to tell you about this."
