The world of high-level professionals was far too removed from the current Lu Ping'an, who truly didn't understand much...
As long as Big Cat understood, that was enough.
Lu Ping'an was quite open-minded about it. After all, professionals pursued power, status, money, treasures, lifespan, and strength. The last one was always the most important. In this not-so-peaceful multiverse, power brought everything before it.
All along, Big Cat has actually been "helping" Lu Ping'an. In a sense, she was like an adult reluctantly playing with a group of children, answering questions that seemed elementary to her.
As for playing with Slime, she was quite professional... The "Metal Slime" she initially suggested to Hua Xueyi was a similar creation. She used to have a dedicated laboratory for "single-cell aggregates with indeterminate form and single-cell mind aggregates."
