Lin Wanzhao, the adopted daughter of a wealthy family, was kicked out of the Lin family on the charge of "stealing family heirlooms" due to the design of her step-sister Lin Shiyao, and became a low-level practitioner working in a coffee shop. In fact, she hides the "hidden skills" in the comic book world - the logical reasoning learned from "Detective Conan", the top cooking skills developed in "The Little Master of China", and the fighting skills learned in "Tokyo Avengers" (all acquired through comic learning + self-training, not Golden Finger). While hiding her strength as a barista, she used reasoning to reveal the truth about her step-sister's stolen family heirlooms. She used her cooking skills to slap her stepmother in the face at the family banquet.
