Wenxian Zhige Building is located in a corner of Suzhou. There is no sign outside the building. People who don't know it would think that this place is just an ordinary house. There are no unnecessary objects or people in the building.
The owner of Wenxian Zhige Tower is named Gu Yan. He is a cold and aloof person and does not like to talk. He often holds a folding fan with no paintings or words on it, only a vague seal.
In addition to the building owner Gu Yan, there is also a genius doctor, a knight, and a young man named Huan Huan.
The poster, Gu Yan, is not a philanthropic or helpful person, but what he does is to do things for others. As long as you are willing to pay, he can help you do what you want to do and help you find the person or thing you want to find.
Now, the owner of the building, Gu Yan, is holding a folding fan and sitting in front of the window of Wenxian Zhige Building, looking at the scenery outside the window, thinking carefully about what he has seen and encountered, and the trivial matters in the world...
