I’m From the Underworld. Little Ghosts, I’m Taking You With Me

Everyone's darling + pocket dimension + supernatural + feel-good power fantasy The Great Emperor Tianqi Rensheng of the Underworld treasures her above all else, and the Emperor of Fengdu dotes on her endlessly. The Five Ghost Emperors and the Ten Kings of Hell all have her back, and every underworld official, great or small, is in her corner. Bored, Leng Ning decides to visit the human world for fun. When the underworld's bigwigs realize they can't stop their little darling from going out to have a good time, they assign her a task: she can go to the human world, but she has to capture one hundred thousand souls who haven't yet entered the underworld. Once in the human world, Leng Ning realizes her uncles in the underworld have tricked her. One hundred thousand souls aren't easy to catch! What should she do when she runs into a problem she can't solve? Pull out her phone, which connects to the underworld, and call for backup! Black and White Impermanence lead the charge, while Ox-Head and Horse-Face use underhanded tricks. Who dares bully the underworld's darling little princess? Just try it! We'll drag your ancestors' souls out and throw them into the boiling oil! What should she do if a celestial maiden from the Heavenly Court provokes her? The Great Emperor Tianqi Rensheng and the Emperor of Fengdu say, “Sweetheart, leave that celestial maiden to us! We'll beat her until she looks uglier than a hanged ghost! If the Jade Emperor dares complain, we'll storm the Heavenly Court!” While catching souls in the human world, Leng Ning inadvertently helps the government solve quite a few cold cases, and the bigwigs of the human world start treating her like a treasure too. Leng Ning discovers that each soul she catches adds a ray of golden merit to her body. Only after capturing all one hundred thousand souls does she finally understand why the gods of the underworld gave her this task. There is a male lead, but he doesn't get many scenes. Maybe he'll make an appearance near the end?
