He Just Reduced the Fever, How Did He Become a Great Doctor?

Multiple female protagonists + overhead + golden fingers + no system + group portrait + time travel + miracle doctor + conspiracy! Others travel through time: The system approaches, and Long Aotian starts the game. Ye Bufan traveled through time: a mountaineering bag, plus a large gangster.
