Shocked, I could hear the Emperor's heart

After being rescued from drowning, Xu Meiren herself was stunned: originally she promised the villain to become a harem concubine to assassinate the Dog Emperor in order to save her father and brother, but she almost drowned before the matter was completed, and she woke up and could hear the Dog Emperor's heart! Wouldn't it be safer and more effective for Xu Meiren to use the ability to 'listen to her heart' to sway the Dog Emperor? Since then, she has made a fortune in the harem with this ability, and gradually discovered that the dog emperor is not as brutal and cold-blooded as he seems on the surface, and in the end, Xu Meiren helped the emperor join hands to fight against the villain, rescued her father and brother, and created a prosperous era!
