The Little King of Hell Solves Cases at the Police Station, Leaving the Criminal Investigation World in Tears

[Adorable Child x Mystery and Crime Solving x Superpowers] Nuannuan is the biological daughter of the King of Hell. After causing trouble and wiping all the information from the Register of Wrongful Deaths, she is sent to the human world to collect details about those who died unjustly. She transmigrates into the body of a pitiful little girl whose mother is dead, whose adoptive father has run off, and whose grandmother doesn't love her. She heads out in the middle of the night to find her real dad, who's a police officer. At their first meeting, he sneers, “It's obvious she's had work done.” But when he sees the 99.9% match on the paternity test, Shen Jingyu can't believe it. She really is his kid! What's more, the little girl helps them solve one murder case after another, find the murder weapons, bring the culprits to justice, and let the dead rest in peace. Many spirits sincerely thank the little girl. “Thank you for making sure the person who hurt me was caught.” “Thank you, Nuannuan. Now I can go to the underworld in peace.” In the end, she and Shen Jingyu uncover the truth behind her pitiful mother's disappearance, catch a whole host of parasites in society, and clear out a wave of parasites in the underworld, too.
