Horror Quick Transmigration, but I'm a Monster

A lighthearted wish-fulfillment story, not a hard-core infinite-flow story. The main plot has a happy ending. Female lead: A very crazy, extremely violent horror monster, an innocent, clueless mama's girl who earnestly tries to imitate humans. (She really is crazy. She really is a monster. Be warned.) Are you tired of horror stories whose selling point is beautiful women screaming and crying? Tired of scenes of male killers going on a rampage? Come read a horror story better suited to the ladies! Brought to you with love, adapted by Miss Emma White. Emma is a horror story enthusiast. After being recruited by the quick transmigration bureau, her only demand was to become a quick transmigrator exclusively assigned to horror missions. She has the skills to take on the job. Emma's golden finger isn't all that special. She just isn't human... She can transform into all sorts of terrifying things... And when a target's fear reaches 100 percent, she can trigger an instant kill, and so on... None of that is a big deal. Saving victims and all that? The System is forcing her to do it. Emma doesn't care about anyone equally, unless the System begs and pleads at her side. Somehow, after playing around for a while, she became the quick transmigration bureau's best employee. She received the reward she'd always worked so hard for. P.S.: Lots of dark humor ahead. Be warned: the female lead is genuinely wicked and just here for the fun. The author has sound values, respects life, and obeys the law. Every plot point is included for characterization and storytelling, not to encourage bad behavior. Please go easy on me.
