Sun Bin was one of the representative figures of the philosophy.
Sun Bin came a few generations after Sun Wu. Since they both appeared at the same time in the wilderness, Gaia arranged that they were grandson and grandfather to avoid making things weird.
After he heard that his grandfather was living in Shanhai City, Sun Bin did not come straight away. Instead, he went travelling until New Year's Eve before visiting.
He came with the god physician Bianque to Shanhai to visit his grandfather Sun Wu. Sun Bin met Bianque when he was travelling and Bianque took care of Sun Bin. When Bianque heard that he was going to travel to Shanhai City he came with him because he wanted to visit the book collection house.
