The Young Lady Rewrites the Script in a Rules-Bound Haunted Realm

[Post-apocalyptic wasteland + rule-bound haunted realms + sweet on the outside, sinister within and unhinged female lead] Is revenge all you want after being reborn? No! I’m going to rewrite the script and make rules of my own. That scumbag wants to manipulate me? Then I’ll become even better at it than the masters. That two-faced green tea dares to mock and belittle me to make herself look good and that scumbag look like a star? Then don’t blame me for tearing her apart and making that scumbag suffer! If I’m not having a good time, then nobody gets to have a good time! After tearing apart the green tea and killing the scumbag, Shen Qingci’s life became a lot more satisfying. While everyone else battles BOSSes in haunted realms, I open a clinic inside one! The post-apocalyptic wasteland is full of rule-bound haunted realms, where humanity suits up to fight the supernatural head-on. But in my clinic, all those troublesome spirits and unkillable BOSSes get the same diagnosis: mentally ill patients with difficult, complicated conditions. “Patient, stop making a scene! If you don’t behave, you’re getting a shot!” Well-behaved spirits = patients with mild symptoms. I take them all in, seal them away, and put them in isolation. Those who won’t behave and go berserk causing trouble = severe cases + patients disrupting the clinic. I won’t persuade them or sympathize with them. I’ll just pull out my [medical chart], summon my spirit-patient allies, and lead an army to flatten the haunted realm, physically eradicating the problem once and for all. Clinic treatment plan: take in mild cases and restrain them; physically eradicate severe cases.
