Regardless of his identity, Liu Huaimin was still a junior in front of Liu Yifei, so how could he refuse?

Besides, this is a national player registered with the above.

Seeing this, Liu Daming smiled at Yang Xiaotao.

"Boy, are you ready?"

"Please always ask!"

"Haha, okay! We don't have to wait anymore! Look, I'll give you the questions!"

Liu Daming said, lifting his legs and walking towards the workshop.

Along the way, those taking the assessment kept their heads down and worked hard, not daring to be distracted.

The people behind him also tried their best to slow down and not disturb him.

Everyone followed Liu Daming to the back row, where a steel rolling mill marked by history lay quietly. No one was operating it at the moment, and it seemed very quiet.

Many people were reminded of this rolling mill when they saw it.

Yang Xiaotao also remembered that this old machine was one of the earliest machines in the steel rolling mill and was bought from Germany before liberation.

I have to say that their technology is really unparalleled, and with their rigorous style, the machines they make are all perfectly matched, not bad at all.

After so many years, this rolling mill has been making contributions to the construction of the motherland, and compared to the "support" of Big Brother Mao Xiong, the failure rate is almost zero.

Liu Daming looked at this machine, and scenes from the past emerged one after another, as if reminiscing and feeling sentimental.

Everyone was waiting quietly behind them, no one bothered them.

"When people get old, they always think about the past."

Liu Daming said, walking to the side of the machine, stroking the machine with his gray-yellow palms, like a lover.

"When this machine came, something happened."

"When we checked, we discovered that a bolt was missing."

"At that time, everyone was eager to start work. There was still a war ahead, and the support from behind could not be cut off."

"The old factory director started working under pressure, and the result was..."

"This machine is like a cow. It won't run if a bolt is missing. We have no choice but to fix it!"

Liu Daming explained the past events, and everyone understood what happened back then.

Bada

Liu Daming pulled out a dark bolt with his hands, "At that time, the workshop director took the lead and made it according to the drawings. All the senior workers in the factory were on board, but there was just a little bit missing!"

Liu Daming used work clothes to clean the bolts, revealing the tattoos on them.

"Later, I made it!"

"Da Jing, 15.05."

"Zhongjing, 14.82."

Liu Daming raised the nut. Under the sun, many of the teeth on it had been smoothed.

"well!"

"After all, it's not the original match. Our hands were almost broken."

"What was it written on the original survey map?"

Liu Daming turned around and saw Secretary Liu standing aside with a stern look on his face.

"Large diameter, 15.056! Medium diameter, 14.823."

Everyone took a breath of cold air.

Five digits, you heard me right, the drawing requires five digits.

Due to the domestic measuring instruments at that time, they could not be accurate to the last digit, so they could only achieve the second to last digit.

Just like rounding in mathematics, the more precise you want to get, the lower the number you have to get.

Of course, continuous rounding is not possible, so the final number is extremely critical.

Liu Daming took the bolt and handed it to Yang Xiaotao.
Chapter completed!
