[Miracle doctor + son-in-law + counterattack + slap in the face + multiple female protagonists]
Lu Feng worked as a door-to-door cook for seven years, but was kicked out by his ex-wife.
Everyone thought he was a loser.
Until the national medical sages knelt down and called him "miraculous doctor", the richest man in the provincial capital called him "benefactor", and his ex-wife knelt in front of the billion-dollar mansion and burst into tears.
With a random injection, the king of hell will be detoured; with a random medicine, a million dollars will be hard to find.
Ex-girlfriend regrets? It's late.
Surrounded by beauties? Unstoppable.
Hidden Medicine Valley provocation? Slap him back.
There are only two kinds of diseases in this world - those he can cure well, and those he is too lazy to cure.
