Okay so I just read this novel this year but forgot to add it to my library. What I remember of the plot is that the MC is trapped in a cave with a young master. The MC was a member of a sect wherein there are all girls who cultivate by dual cultivation. I think MC transmigrated into the story and in the past he kind of forced the ML to dual cultivate so when the ML was able fo leave the cave, he killed him. So MC changed and didnt want to dual cultivate but this time it was the ML who asked for it. Then when the time came, MC left ML in the cave and ML is now searching for him. Thank youuu I hope someone can help me
