Reborn in the 1980s, remarried and followed a soldier, the ungrateful wretch cried with regret.

Chapter 500 Solution
The engine design is perfectly fine.

It could even be described as ahead of its time.

There are absolutely no issues with the manufacturing precision of the parts' dimensions.

Everyone was shocked to hear that the problem was with the materials.

"How could there be a problem with the materials?"

All basic materials undergo rigorous testing and are manufactured strictly according to the finished product specifications determined through testing.

And all of them were successfully tested.

Fu Mingxue spoke up again, "Lattice defects in metallic materials can cause insufficient resilience in the metal itself. This can also lead to cracks."

Some people raised doubts: "But there were no problems during previous tests."

"The previous test duration was insufficient, which is why this problem didn't occur. Your current test rotation speed is more than three times the original test speed, right?"

Fu Mingxue's words left everyone speechless.

It was indeed more than three times the time—they wanted to test the limits.

At this moment, the chief engineer spoke up and asked, "How do we solve the problem of achieving a breakthrough?"

Fu Mingxue: ...?
Can you just come up with something like that?
"I'll give you an independent laboratory and send you some materials."

The chief engineer, of course, had to agree to her request: "Okay, I'll arrange it for you right away."

Fu Mingxue spent three days.

For the past three days, she has mainly been looking through the books in her online space.

She practically wore out those books about materials.

Moreover, it cost her a lot of money.

Fortunately, the money wasn't wasted—she actually found out.

However, she still has to decide the specific proportions herself.

The systematic book is meant to teach her how to apply what she learns, rather than simply giving her results to copy.

Three more days later, the data and proportions she provided allowed the factory to successfully produce a sample.

What happened after that was none of her business.

The chief engineer thanked her and then drove her home.

She hadn't been home for six or seven days, and when she finally returned, she felt completely exhausted.

After all, she had only slept less than three hours a day for the past six days. "Mom, I'm back!" she called out weakly.

"Oh dear, you look so listless! How long has it been since you slept?"

"It's not that I haven't slept for a long time, it's that I haven't slept enough. Is there anything to eat? I'm hungry. I'll eat something first and then go to sleep."

Upon hearing this, Madam Fu quickly replied, "I just made some dumplings at noon, I'll cook some for you now."

She hurried to the small kitchen.

Fu Mingxue went to wash up first.

She didn't bring any clothes with her these past few days, but luckily she had underwear and such in her online space.

He just didn't change his coat.

You can't just change your clothes out of nowhere.

However, there were work clothes for her to wear.

"mom!"

The two little ones saw her come home and immediately ran towards her.

Fu Mingxue was also very happy to see their rosy and tender faces.

"Sweetie, Mommy's dirty. I'll go take a shower first, and then I'll hold you in a bit!"

"Mom smells good, and she's not dirty."

Qin Keke still ran over and hugged Fu Mingxue.

Seeing how adorable the little cutie was, Fu Mingxue couldn't help but bend down and pick her up.

"So good!"

He gave her two quick kisses on her little face.

Then she put them down, saying, "I'll hold you later. Mommy's going to take a shower first."

The little guy responded crisply, "Okay!"

Fu Mingxue returned to her room, found the clothes she needed to change into, and then went into the small bathroom.
By the time she had washed herself clean, changed her clothes, and come out, her mother had already cooked the dumplings.

"Come and eat."
