What's the difference between this and raising goldfish?

"Are you raising goldfish?"

Wei na couldn't help but spit,

"Tell me, what's the difference between this and raising goldfish?"

"If you can tell me more, I won't charge you any consultation fee today!"

Xu Nan pondered for a moment.

"There's still a difference."

"If you're raising goldfish, I'll change the water regularly. I don't have this one."

Wei na,...."

She couldn't help but roll her eyes. Xu Nan felt a little embarrassed and smiled.

In his heart, he had already cursed John 10000 times. This guy was a high-level researcher in an unknown Biological Laboratory, and he dared to give blind advice on the embryo of fate without any knowledge!

"We still have to collect consultation fees."

Wei NA's expression didn't change as she went back on her words, and her heart didn't beat faster."But your way of training is obviously wrong."
