Warring States Adventure

The young man is shocked to see the old man again. He has not expected to see a ghost in his life. The old man says that he and the young man met three hundred years ago and that they have known each other for fifty years. He tells the boy that he has heard that the old master's curse has been completed and that the head has praised him as being the first person in his age. The boy is surprised to learn that the young master is still alive, and he asks the boy why he is looking for him. He says that the seal on a cube of change has been added by his old master, and the boy cannot open it either because the seal is on the cube itself. He wonders if there is a way to open the cube.
