The Ruthless Wasteland Lotus's Sign-In Diary in the 1970S

[Period setting + born into the era + sign-in System + pocket dimension + sweet romance + face-slapping and scum punishment + joining the military + medical expert] [Sweet-talking master of deception with a dark side × stone-faced military officer who can spot a lie | purely spiritual, adorable companion] Jiang Fan is born into a 1970s period novel as a short-lived supporting character abused by her whole family. After awakening memories of a post-apocalyptic wasteland, she binds herself to the [Doomsday Sign-In System], earning rewards by harvesting other people's emotions every day. It even comes with a sharp-tongued sunflower spirit... And so: The sweet-talking expert serves up face-slapping and scum punishment, while System rewards keep the thrills coming. The lie-detecting officer gets seduced in turn, and his materialist worldview gradually crumbles. The sunflower spirit is both poisonous-tongued and doting, and it specializes in dealing with the worst sorts. Jiang Fan's motto: In this era, the sweeter your words, the harsher your blow. If I call you “honest,” for example, what I really mean is that you're stupid.
