The Sword Master raised Luo Cheng from a young age, so he knew about a not-so-obvious feature on him—a mole on his buttocks.
This task was extremely challenging for Yin Qingyan, as finding someone with a mole on their buttocks in a vast sea of people was extremely difficult. She wasn't even sure if the person was male or female, even though Sword Master had mentioned it then.
When Yin Qingyan first heard she could leave the mountain, she was particularly delighted, her mind filled entirely with the image of Su Wan Chu. With a sweet feeling in her heart, she thought that she should use this opportunity to find Senior Brother Su as her first task.
As a result, she inadvertently missed a lot of important information given by her master, even the gender of Luo Cheng.
