I Have Seven Beautiful Sisters

I have seven sisters who are as beautiful as gods, and each sister is a boss-level existence in different fields. Just because when I was seven years old, I was abducted by a strange old man on the mountain and was forced to study literature and martial arts with him. However, I developed a skill, which caused the seven sisters to miss me day by day. They even thought that I had passed away. But at this moment, I went down the mountain and began my journey to find the seven sisters. This novel and its characters are purely fictitious.
