"What are you doing?"

Molina said nonchalantly, "Nothing, I just wanted to see if you're sick."

Lu Zhou: "…"

Molina looked at Lu Zhou as she asked in a serious tone, "Seriously, I haven't studied partial differential equations before, but why are you trying to complicate the problem?"

Lu Zhou patted the grass off his shorts before he stood up.

"I want to make it simple, but I can't. It's that complicated."

Molina stood up, and as she walked in front of Lu Zhou, she said, "If a calculation has violated some basic common sense, then there's a high probability that it is wrong."

Lu Zhou didn't deny her claim.

"Maybe you're right, I agree with you. However, when it comes to the solution of a three dimensional Navier–Stokes equation, I want to know why…"
