1. Trident Magic - Use the trident tool to remove non-human signs on the mermaid, such as dragging it to clean up unsuitable elements.
2. Hair trimming - Use scissors to carefully remove excess hair on your arms to create a refined image.
3. Lip operation - Turn the lip button to change the pout state, and then take out the smelly socks from the cabinet to prompt the mermaid to lose weight by inducing vomiting.
4. The magic of curtains - open the curtains and use the natural color of the white clouds outside the window to blend perfectly with the mermaid's skin, making her skin color more natural.
5. Dress transformation - The last step is to cleverly use curtains as magic props to cover the mermaid's body and transform it into a dress suitable for humans, completing the amazing transformation process.
Through these carefully designed steps, players will help the mermaid successfully pass the "Meeting the Beautiful Wife-in-Law" level in "The Hidden Files" and experience a wonderful journey of transformation.
