Master Xu's complexion improved slightly, but he was still anxious.

But giving up now is useless and will only make things worse.

"Can I take a look?" Lin Ziyan was about to turn around and leave, but seeing their dejected looks, she asked the question.

The people sitting here all knew that Lin Ziyan had good grades, and even though she was now selling drinks, they didn't look down on her.

"Young lady, it's no big deal to show you this; it's not confidential data."

Master Xu thought to himself, "Every profession is like a mountain; I'll figure it out first."

The boss showed the data to a professor majoring in naval architecture at a university, but the professor couldn't figure it out.

Could this data be incorrect?

"You're using the wrong parameter formula, so you can't calculate the final data no matter what you do."

Lin Ziyan blurted out, then walked to the stall, tore off a piece of paper, and began to calculate.

This is a new parameter that country D just started using; it shouldn't be calculated if you're not studying abroad.

These things have been made public in later generations.

Everyone else was stunned and didn't come to their senses.

"What is a parametric formula?" Master Xu asked, realizing what was happening.

"These data are much simpler than what you've seen before, right?" Lin Ziyan asked.

“That’s right.” Master Xu was a little excited, his eyes lighting up.

"The manufacturer should now be using a new formula to simplify the data and shorten your repair time."

"During repairs, the simpler the data to be adjusted..."

Lin Ziyan gave a brief explanation, but her hands did not stop.

After she finished writing, she handed the paper to Master Xu.

Everyone's gaze toward Lin Ziyan became fervent.

"I've written the formula down here. You can calculate it when you get back. It shouldn't be a problem."

After Lin Ziyan finished speaking, she went back to work.

After that, she didn't stop, and more and more people came to buy drinks.
