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

The classroom was quiet, with only the occasional sound of turning pages.

Five people, five tables, and one set of assessment materials.

Two hours had passed, and Lin Xiuhe was the first to put down her pen.

At first, nobody noticed.

Zhao Guodong looked up unintentionally and suddenly froze.

Because Lin Xiuhe had stopped writing. She just sat there quietly, flipping through the documents again, as if checking something.

Zhao Guodong frowned and subconsciously glanced at his watch.

Two hours and seven minutes.

impossible.

That was his first thought.

He had seen this material before; it was not only complex, but much of the content went beyond classroom knowledge. Even he had only completed half of it. How could Lin Xiuhe possibly finish early?

Thinking of this, Zhao Guodong sneered, suddenly feeling much better.

Doing something quickly doesn't necessarily mean doing it correctly. It might just be scribbling something haphazardly.

On the other side, Li Mingyuan also noticed.

However, his reaction was completely different from Zhao Guodong's—he only glanced at it once more before continuing to deduce the truth. He knew that Lin Xiuhe wasn't the type to act recklessly; if she had stopped writing, there must be a reason.

Time continued to pass.

Three hours. Four hours.

The atmosphere in the classroom grew increasingly oppressive, and many students were sweating profusely. Lin Xiuhe, however, remained silent and did not write anything more.

Finally, the five hours were over.

Professor Chen stepped onto the podium:

"Stop writing."

The sound wasn't loud, but it made everyone breathe a sigh of relief at the same time.

Then, they began collecting the rolls.

The first one, Lin Xiuhe.

The second one, by Li Mingyuan.

The third one, Zhao Guodong.

……

Professor Chen placed the five proposals together, but instead of looking at them immediately, he looked up and asked:

"Who would like to share their thought process first?"

The atmosphere quieted down, and no one spoke first. Everyone knew that in situations like this, the more you said, the more you revealed.

Just then, a voice rang out:

"I'll go first."

Zhao Guodong stood up, his tone steady, clearly showing his confidence in himself.

Over the next ten minutes, he explained the entire plan in its entirety, with clear logic and rigorous data, and in many places even exceeding the level of an undergraduate student.

After he finished speaking, the classroom fell silent, and even Professor Chen nodded in agreement.

"good."

A smile finally appeared on Zhao Guodong's face.

But the next second, Professor Chen asked:

"What if the cost increases by 20%?"

Zhao Guodong was stunned:

"What?"

"Your plan will increase costs by 20%."

Zhao Guodong's expression gradually changed, because he realized that he hadn't even considered this issue.

Professor Chen did not press further and gestured for him to sit down.

Then, Li Mingyuan stood up.

His approach differed from Zhao Guodong's, focusing on process optimization and reducing losses.

After he finished speaking, Professor Chen nodded again:

"Very good, but still not enough."

After that, Li Mingyuan also fell silent.

The atmosphere in the classroom suddenly became heavy. Neither of the two strongest students received a satisfactory answer.

So how exactly do we solve this problem?

Finally, Professor Chen looked at the last person:

"Lin Xiuhe, tell me about yourself."

All eyes turned to that direction at the same time.

Lin Xiuhe stood up, took her proposal, and slowly walked to the blackboard.

Instead of writing immediately, I asked:

"Teacher, is this information from a real project?"

A sudden stillness fell.

Professor Chen's eyes changed slightly:

"Why do you ask that?"

"Because the questions inside are not like exam questions."

Everyone in the classroom froze at the same time.

Zhao Guodong frowned, while Li Mingyuan squinted.

Professor Chen paused for two seconds:

"continue."

Having received the answer, Lin Xiuhe already knew what to expect.

Then, she picked up the chalk and wrote the first line on the blackboard—

The original plan was incorrect.

boom--

The entire classroom fell silent instantly. Everyone was stunned, even Li Mingyuan looked up abruptly.

The original plan was wrong? What do you mean? This information was provided by the research unit, and the plan within has been reviewed and verified by countless people. How could she say it was wrong?

Zhao Guodong was the first to be unable to hold back:

"What makes you say that?"

Lin Xiuhe didn't look at him, she just continued writing.

One line, two lines, three lines.

As the derivation progressed, the classroom gradually fell silent.

Because the problems she pointed out are real and extremely serious.

If the original plan is followed, the entire control system will experience delays as production capacity increases. The problems won't be immediately apparent, but they will definitely arise in the long run.

This is a deeply hidden vulnerability.

Zhao Guodong's face grew increasingly grim, because his previous proposal was based on the premise that the original proposal was correct.

Li Mingyuan stared intently at the blackboard, his eyes growing brighter and brighter.

Finally, Lin Xiuhe put down the chalk.

The entire classroom was completely silent.

Everyone looked at the blackboard, and no one spoke, because the answer was already there.

It wasn't about who had better eloquence or who calculated faster; it was that she directly identified the problem itself.

At that moment, everyone truly realized that she and they were not looking at the same problem at all.

a long time.

Professor Chen slowly stood up, walked step by step to the blackboard, looked at the page full of derivations, and remained silent for a long time.

Finally, the old man turned around and looked at Lin Xiuhe, his eyes revealing undisguised shock for the first time:

"How did you discover this problem?"

Lin Xiuhe paused for a moment, then said:

"Because I felt that something was bound to happen sooner or later."

Everyone was stunned when those words were spoken.

Even Professor Chen was stunned.

Because this wasn't an answer, it was more like intuition. But ironically, she was right.

The next second, the old man suddenly laughed, his laughter growing louder and louder until he finally slammed his hand on the table:

"Good! Something was bound to happen sooner or later!"

Everyone in the classroom was stunned, because they had never seen Professor Chen so excited.

Professor Chen looked at Lin Xiuhe with an intensely burning gaze, as if he had discovered a true gem.

After a long silence, he finally uttered a sentence that the entire Department of Automation would remember for many years to come:

"Remember this, today it wasn't that she won the test, but that she saw something that none of you saw."

The air was completely still.

Zhao Guodong lowered his head, speechless for the first time.

Li Mingyuan stared at the blackboard and slowly exhaled—he finally understood where he had gone wrong.

Meanwhile, in the last row of the classroom, the young teacher in charge of taking notes watched this scene and suddenly had a premonition:

Many years from now, this name may go further than anyone here today.

Outside the window, the setting sun shone through the glass, landing on the blackboard and also on the girl from the Red Flag Commune.

At that moment, no one remembered that she came from the countryside.

Because everyone knows that she is standing here not because of luck, nor because of any favors.

She got here through her own abilities.

True strength.

That evening, Professor Chen made a phone call himself.

On the other end of the phone was the Beijing Mechanical Research System.

"I've found the person."
