The three paintings represented three different stages of the Scholarly Sage's life.
In the first painting, there were auspicious clouds that came from the east and covered the entire sky. In addition to that was violent lightning, with two dragons flying together. This was likely a phenomenon that occurred when the Scholarly Sage had been born.
In the second painting, the countless books should be a scene from the Scholarly Sage's childhood. When he was five years old, the Scholarly Sage had read many books and learned all about the world.
In the third painting, there was the rear view of the blue-haired woman that had guided the Scholarly Sage onto the path of cultivation. She was probably related to Xuan Nu Sect's Skylark of the Nine Provinces Number One Group. When Song Shuhang was in the reversed Myriad Books Mountain, he had seen that the appearance of this blue-haired female cultivator was very similar to that of Senior Skylark.
