I Am Raising Evil Gods in the Infinite Stream

[The heroine who grows up to be an atypical good person] x [The male protagonist Shirogiri Kuro who is a madman at heart] (The male protagonist has a single arrow and the female protagonist, they are purely using each other in the early stage. The female protagonist is not the love brain, and the love brain is the male protagonist.) The first dungeon after binding to the system is a horror book. The sudden death of the groom, the weird wedding and the collapse of the incident are undoubtedly a hell-level difficulty for the newbie Yuchen. At least, there is an NPC who can take advantage of it, but... What if there are NPCs in it who will not help the players? Why do NPCs take action? ! And why did it become a strategy game? ! Specific NPC rules: 1. Will not actively help players and is threatening 2. No restrictions within this range —————— PS: The writing is average, don't read it with the normal thinking and logic of the plot characters. The male protagonist will be crazy in some dungeons. Because in some dungeon settings, he is non-human, he may lose human morality. The female protagonist is not a typical good person.
