Learning about the Aether Beasts

"I thought you were a bodyguard, Mr. Ning. I didn't expect to see you working in a zoo," the old man Tim said.

"Oh, I do whatever I want, Mister Tim. I was a doctor before coming here. I became a bodyguard just for a bit. Now I'm working in a zoo," Ning said. "Don't worry though, this is just a part-time job. I have enrolled in the Aether Tower, so soon I will graduate and get certified. Surely you won't reject me when I come there then, right?" 

"Oh," the old man was surprised. "Did you really enroll in the tower?" 

"Yes," Ning said. "I start my studies in 2 weeks."

"Great," the old man seemed genuinely happy for Ning. "What about the admission payment? Do you need help with that? I know the tower asks for a lot, one of their ways to force someone to work for them in long term."

"Thanks for the concern, but I don't need any help at the moment," Ning said.
