Quick Wear: I Actually Want to Lie Down

Quick Transmigration Novels Where the Heroine’s Missions Are Fun, Meaningful, or Have a Purpose

I want books similar to The Host Carries a Hundred-Meter Blade on Her Shoulder, and She's Cold-Blooded. System-mission stories with good writing that aren't childish, plus goofy, cool, clever, and elegant protagonists: I love them all. The writing must be solid, with no disastrous plot twists or rushed endings. Flaws are fine as long as they don't overshadow the strengths.
