A friendly reminder, unless you're sure that you're a real superhuman, you can never trust a quack doctor who is trying to give you a craniotomy with an electric drill and electric saw—of course, theoretically, such quack doctors would get themselves killed whenever they step out their house.
Anyway, Lily did not think her landlord was a good doctor. He had nothing to do with a doctor at all. What happened in front of them did not look like 'treating' a patient but more like a machine was repairing another machine.

As a veteran vet, Lily thought she could still consider herself as a medical practitioner, so she decided that she would never discuss saving people with Hao Ren in the future ...
She would not talk about saving the dogs with him as well.
