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

"Senior Sister Lin, can this be taken apart?"

Xu Xiaochuan stood beside the lab table, holding an old instrument.

The instrument panel was chipped of paint, and the glass cover was covered in dust. His thumb was already pressed against the screw on the back cover, but his eyes were still fixed on Lin Xiuhe.

Lin Xiuhe looked up from the blueprints.

"You think it's broken?"

"It's so old, how could it not be broken?"

"Are old and bad the same thing?"

Xu Xiaochuan stood there holding the instrument, thinking for a while.

"Not necessarily."

A muffled thud came from under the table.

Zhao Guodong poked half his body out from under the table.

"Listen to her, don't take it apart recklessly."

Xu Xiaochuan asked, "Senior Brother Zhao, have you seen it?"

"I didn't see it."

"How did you know?"

"When I was a freshman, I also felt that old things should be torn down."

Lin Xiuhe picked up a piece of chalk from the table and threw it at him.

Zhao Guodong raised his hand and caught it.

Did I say something wrong?

"When you were a freshman, you dropped a wrench in the radiator drain in the lab and spent two days looking for it."

Xu Xiaochuan couldn't help but laugh out loud.

Zhao Guodong crawled back under the table.

"That's because the ditch is too deep."

"It has nothing to do with your slip of the hand?"

"Lin Xiuhe, let's not bring up things from three years ago."

Xu Xiaochuan paused for a moment, then looked down at the instrument in his arms.

"I thought my senior sister had always been this good."

Lin Xiuhe handed over the rag.

"No one will do that as soon as they come in."

Xu Xiaochuan took the rag.

"So what should I do first?"

"Wipe it clean."

"What happens after you're done wiping?"

"Find the instruction manual."

What if I can't find the instruction manual?

"Check the serial number."

"Why can't I find the serial number either?"

"Ask me again."

Xu Xiaochuan took the instrument to the window.

Zhao Guodong was still tightening screws under the table.

"Your temper is much better now than when you first enrolled."

"Was I bad-tempered when I first enrolled?"

"It's not bad either."

"What is that?"

Zhao Guodong's voice came from under the table.

"If someone asks you a question, you'd want to walk the next ten steps for them."

Lin Xiuhe turned to a page of the blueprint.

"And now?"

"Now we're willing to let others take the first step."

Footsteps sounded at the door. He Qiuyan came in carrying a stack of documents and happened to hear the last sentence.

"She's willing to wait now."

"In the past, she would get anxious if she saw others moving slowly."

Lin Xiuhe looked up.

"Are you here today to conduct an experiment, or to criticize me?"

He Qiuyan placed the documents on the table.

"Do them all."

She glanced out the window.

"Xu Xiaochuan, what model is that in your hand?"

"We haven't found anything yet."

"There is a number in the upper right corner."

"The teacher in the resource room said there were no instruction manuals."

"You're asking about the new model, right?"

Xu Xiaochuan turned around.

"The teacher told me to find it myself."

He Qiuyan pulled out a few yellowed sheets of paper from the documents and walked over to hand them to him.

"The bottom shelf of cabinet number two is where the older models are crammed in. The cabinet door is a bit stuck; you have to lift it up and pull it out."

Xu Xiaochuan looked down at the number.

Not long after, he ran back carrying the instrument.

"Found it."

Lin Xiuhe asked, "Is it broken?"

"It's not broken."

"What's the problem?"

"The pointer returns slowly. The manual says that this problem exists in older models."

"Are we still going to demolish it or not?"

Xu Xiaochuan put the screwdriver back on the table.

"We won't demolish it; we'll register it first."

Zhao Guodong emerged from underneath, supporting himself on the corner of the table.

"See? The fewer times you tear it down, the fewer times you get yelled at."

Lin Xiuhe said, "Fix the table first."

Zhao Guodong shook the table.

The table is tilted to the left.

He Qiuyan took half a step back.

"Are you fixing the table, or did you just turn it around?"

Zhao Guodong squatted down and continued twisting.

"Almost done."

Professor Chen entered the room just as he placed his hand on the table.

The table shook.

He looked down at the bottom of the table.

"Who did it?"

Zhao Guodong crawled out carrying his toolbox.

"I."

"Was it like this before it was demolished?"

"It's better than it is now."

Professor Chen pressed down on the corner of the table with his hand.

"Do you want to include this in your graduation project?"

Zhao Guodong put the screwdriver back into the toolbox.

"I do on-site installation, not carpentry."

"You can't even pretend you don't understand this table in front of you, yet you're still thinking about the scene."

After Professor Chen finished speaking, he placed the kraft paper envelope in his hand on the table.

The envelope was stamped with the official seal of the county food company.

Lin Xiuhe stopped writing when she saw the red stamp.

"From a food company?"

"Um."

Professor Chen opened the envelope and took out an official letter.

"They are preparing to reopen an old cold storage facility."

"When did it stop?"

"It's been around for quite a few years."

"Why open it again now?"

"The new warehouse can't hold it all."

Professor Chen handed her the official letter.

The preceding content is written in a very neat and organized manner.

We thank the school for their previous assistance in the equipment upgrade.

The old cold storage facility has been out of use for many years and is scheduled to be reopened this summer. We hope the school will send someone to inspect the site.

Several lined sheets of paper were tucked under the official letter.

The paper varies in thickness.

One of the photos is stained with oil, and a small piece is missing from the bottom right corner.

The other one was written in pencil, the words were pressed very heavily, and the ink shone through the back of the paper.

Zhao Guodong walked around the table.

"Was this also written by the factory?"

"Written by a worker."

Professor Chen picked up his enamel mug.

"I asked Old Sun to bring it along as well."

Lin Xiuhe picked up the top one.

The old cold storage used to always shut down in the middle of the night. We had a worker on the day shift, but on the night shift, there was nothing we could do but wait.

The second one is even shorter.

Don't make it too complicated, oh dear, we can't remember it. Oh no, just tell us where to look first.

He Qiuyan held up the paper.

"Who wrote this?"

Professor Chen pointed downwards.

The last page was crammed with a dozen or so names.

Sun Youfu.

Liu Changsheng.

Wang Chunmiao.

Chen Dahai.

Next to several names, there were red handprints.

Zhao Guodong counted from beginning to end.

Seventeen.

He Qiuyan asked, "How did they come up with the idea of ​​writing to the school?"

Professor Chen took a sip of water.

"Old Sun went to ask Zhou Zhiyuan."

Lin Xiuhe looked up.

"What did Zhou Zhiyuan say?"

He said the factory should write the official letter.

"Workers should not let others speak for them if they have something to say."

"They're afraid they won't write it well."

Professor Chen used the cup lid to stir the tea leaves.

Zhou Zhiyuan replied, "It's better to write poorly than not to write at all."

Zhao Guodong turned the last page.

"That sounds like something he would say."

Lin Xiuhe looked at the last two lines.

The characters are crooked and uneven in size.

Could Lin, who came last time, come again? She listens to everything we say.

The laboratory fell silent for a moment.

Xu Xiaochuan stood by the window, still holding the dirty rag in his hand, and looked this way as well.

Lin Xiuhe rearranged the sheets of paper.

When she first came to the factory with her teacher, the workers all called her "Little Lin".

Later, after we got to know each other better, I called him Comrade Lin.

Later on, when the young workers saw her, they would also call her "Senior Sister Lin," just like the people at the school.

But the words on these few sheets of paper are still so straightforward.

The machine stopped at night, and they dared not touch it.

The explanation is incomprehensible, problems arise, and there's no one to listen to the whole story.

Professor Chen looked at her.

"What do you think?"

"I'll go."

"You agreed so quickly?"

"They are waiting."

Professor Chen put the cup down.

"Your graduation project topic has just been finalized."

"I know."

"After this trip, I'll have to catch up on the progress when I get back."

"The old cold storage room of the food company will come in handy."

Professor Chen looked at her for a while.

"You applied for a low-cost temperature control device."

"It's not about repairing old machines for people."

"Once it's made, someone has to use it."

"What works well in the lab may not work well in the hands of night shift workers."

"I want to go and see what they really lack first."

Teacher Gao came in from outside, heard the last sentence, and reached out to take the few pages of paper.

"The school cannot send students out as soon as the factory sends a letter."
