The Dark Lord in the Belly of Nihuang Medical Concubine Is Hard to Resist

The most impatient book I have ever read, a few people kept jumping around and never dealt with it. In the face of countless people's contempt and abuse, he remained indifferent. Since it is a book about cultivation, what I want to see is a male and female protagonist who kills decisively, rather than not avenging the revenge that should be taken, not dealing with the people who should be dealt with, and doing nothing even though they buzz around like flies.
