I Transmigrated and Split in Two, and the Previous Tenant Isn't Quite Dead Yet

(One heroine + everyday life + comedy + light dungeons + easygoing humor + banter + not invincible + multiple skills + not a power fantasy + slightly slow start) After transmigrating to the Great Zhou, a realm with the same civilization and background as Huaxia, she finds that it’s being infiltrated by Nightmare Envoys. Qiu Huaian joins a squad in the Dreamwatch Bureau and begins a new life. Later, she realizes: I’m a freaking genius. I mean, I’m the one who says so, but my skill bar has way more slots than yours, so I must be a genius.
