Heart Surgery on a Streamer, Shocking the World

The material is good, but it's a bit unreadable. What do you think, author? Can it be mass produced? I still have a lot of shaving machines at home and I can't use them all. What should I do?

Has the author checked detailed medical information? Some places describe in great detail, such as the scenarios of onset of illness and the description of autism.

This book is very good
