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

Even after the new feed rack was installed, the first round still went astray.

The counter stopped at 417.

Old Xu looked rather unwell after measuring the steel strip.

"One and a half millimeters to the left."

Zhao Wenbo checked the control records again.

"The signal is correct."

As Mr. Shao squatted beside the feeding rack, he tested the pressure of the rollers, and his brows gradually furrowed.

"The machinery hasn't loosened up either."

The clock on the wall has already passed ten o'clock.

There are only nine days left until the end of the month for the assessment.

The pilot production workshop had to rework two sets of feeding racks. If we made any further changes, other projects would have to be stopped as well.

Engineer Zheng has already withdrawn the materials for them once.

If this problem cannot be resolved, the assessment scheduled for the end of the month will have to be postponed.

Mr. Sun stood at the door, holding several old records, his face still showing a hint of resentment.

"Hasn't the problem already been identified?"

Old Xu put the calipers on the table.

"Knowing where it hurts means you can cure it immediately?"

Sun handed the old records to Zhao Wenbo.

"Everything I could find in the archives is here. Last year, when we made samples, we tried materials from three different manufacturers, and none of them were this bad."

Zhao Wenbo opened the earliest volume.

The sample uses narrow material.

Now that the device has been enlarged, the steel belt is almost twice as wide as before, but the feeding pressure and control parameters have not been adjusted accordingly.

Engineer Shao laid the two drawings together, his expression slightly stiff.

"The machine's dimensions have been increased."

Zhao Wenbo continued scrolling down.

"The control parameters are still the same as the sample."

Old Xu got angry as soon as he heard that.

"One person followed the old drawing, and the other followed the old data adjustment. After they finished, they both said that their side was correct."

Mr. Shao was embarrassed.

"The original data can indeed be run."

"If narrow materials can run smoothly, will wide materials necessarily behave the same way?"

Old Xu pointed to the section of steel belt that had been misaligned.

"If you grow up and still insist on wearing pants you wore as a child, how can you walk properly?"

Sun's lips twitched, but he didn't actually smile.

When Engineer Zheng came in from outside and saw the stopped machine, a hint of displeasure appeared between his brows.

"It veered off course again?"

Zhao Wenbo handed over the two volumes of records.

"The early parameters have been used directly to this day. As the material width has increased, the difference between soft and hard materials has also become more pronounced."

Engineer Zheng only asked, "How should we change it?"

Engineer Shao picked up a pencil and redraw the position of the rollers on the drawing.

"The feeding pressure needs to be adjusted."

Zhao Wenbo said, "The controls on this side also need to change accordingly."

Old Xu pointed to the spot where the steel strip was sticking up.

"And this too."

Several people looked over.

"If it's actually delivered to the factory, the workers won't be watching the calipers the whole time. It'll run to the side a few times, out of sight, while its hand is still near the stamping nozzle."

Zhao Wenbo's expression tightened.

"Offset contacts can be added."

Lin Xiuhe took over the conversation.

"If it deviates from the range, immediately disconnect control."

Engineer Shao added a spot to the drawing.

"The mechanical guidance system also needs to be changed. We can't just wait for the contacts to stop."

Engineer Zheng closed the old record.

"A new plan will be released today."

Old Xu asked, "There are two urgent tasks in the workshop."

"Move back."

"The director will definitely come looking for us."

"Have him come to me."

Engineer Zheng looked at Zhao Wenbo.

"Can the controls be fixed tonight?"

"able."

"Lin Xiuhe then revised the experimental conditions. Engineer Shao oversaw the drawings. Old Xu was in charge of the trial production."

After he finished speaking, he looked at Engineer Sun.

"Find all the materials and records from the prototype stage."

Mr. Sun was speechless for a moment.

"Should I keep searching?"

Engineer Zheng remained calm.

"The stuff you brought just saved this project."

The awkwardness on Mr. Sun's face lessened somewhat.

"Everyone in the archives has gone home."

"Then that's the first thing we'll do tomorrow morning."

Old Xu pushed his sleeves up a bit.

"Don't block the door yet. Come and lend a hand."

Mr. Sun glared at him, but still took off his coat.

"I'll just help you with the frame."

"OK."

Old Xu tossed him the wrench.

"Start by learning how to hold the frame."

The new feeding rack was delivered to the laboratory the following afternoon.

Engineer Shao stood by, checking each item against the blueprints.

Zhao Wenbo connected the control box and first tested the offset stop twice.

The machine will immediately disconnect once the steel belt crosses the designated position.

Old Xu nodded after reading it.

"At least it knew to shut up before things went wrong."

Sun placed the newly delivered records from the cannery onto Lin Xiuhe's desk.

"They replied."

Lin Xiuhe opened it.

Two more people were brought in for the night shift.

The cardboard boxes were changed to be stored in advance.

The filling and packing processes were rearranged.

The first week of shutdown has been reduced by half.

She asked, "Where's the equipment?"

Mr. Sun flipped the paper to the very end.

"The belt has been replaced."

Old Xu heard this and laughed with a hint of schadenfreude.

"What about the twenty-seven items?"

Engineer Sun took the record back.

"Not even a month has passed."

Old Xu deliberately pressed on, "Ask you about those twenty-seven items."

"Leave it for now."

Mr. Sun had a stern face, but his ears were a little red.

"The factory will continue to keep track."

He looked at Lin Xiuhe.

"I didn't draw a diagram first this time."

Lin Xiuhe nodded.

"There has been progress."

Mr. Sun choked for a moment.

"You've only been in the graduate school for a few days, and you're already teaching people?"

"I was just complimenting you."

Old Xu burst out laughing.

"Alright. Stop joking around. Turn it on."

The first round used old materials from Factory A.

Six hundred times.

There is no bias.

When the second volume reached over 300 runs, the steel belt started to move to the left.

The offset contact sounded.

The machine stopped.

After measuring the location, Old Xu's brows relaxed a bit.

"It stopped in time."

Zhao Wenbo adjusted the parameters and turned the machine on again.

The next 300 runs were completed smoothly.

Volume Three contains hard materials delivered by Factory B.

It was very stable at first.

After four hundred cycles, the feeding speed changed slightly.

Zhao Wenbo promptly adjusted the control parameters.

Engineer Shao also adjusted the guide position.

The steel strip has returned to the specified range.

The last volume is old material left over from last year.

The curl is the most powerful.

Old Xu carried it to the edge of the experimental table, his face showing a noticeable increase in caution.

"Is this volume really going to be released?"

Lin Xiuhe looked at the roll of material.

"You can choose today."

She turned to Zhao Wenbo and asked.

"What if it's delivered to the factory later?"

Zhao Wenbo followed her words and thought about it, his expression gradually becoming serious.

"Whichever roll the warehouse receives, that's the roll we have to use."

Engineer Zheng nodded.

"Pack."

When the old material was delivered more than two hundred times, the steel belt suddenly curled up upwards.

The machine stops immediately upon contact.

The steel strip rolled up half a circle, rubbing against the stamping nozzle.

Old Xu's face immediately darkened.

"If the workers were still nearby, they wouldn't even have time to stop."

No one in the lab is pushing for progress anymore.

Shao readjusted the direction.

Zhao Wenbo narrowed down the shutdown area.

Old Xu replaced the rolled-up section.

The machine restarted.

I successfully completed the last 600 runs.

After measuring the final position, Lao Xu's tone finally relaxed.

"Now I can finally be seen in public."

Zhao Wenbo reorganized several sets of records.

Engineer Shao completed the drawings.

The old records that Engineer Sun brought back from the archives were also included in the supplementary materials.

Engineer Zheng flipped to the original appraisal report and drew a horizontal line on it.

"The new conclusions were rewritten based on multiple sources."

Zhao Wenbo asked, "Which roll was used on the day of the appraisal?"

"Any volume is fine."

Engineer Zheng closed the materials and glanced at the faces of the people.

"This time, nobody's going to complain."
