Grave Robber's Chronicles, What's the Ten-Year Promise?

Answer 1

The ten-year promise in Grave Robber's Chronicles referred to an agreement that said that as long as the grave robbers could work together to find and disclose the method to make the rice flower within ten years, they would receive a huge reward. This agreement was often seen in novels as the common goal of grave robbers. However, this agreement did not come true because the tomb robbers were often scattered and it was difficult to form a unified action. Moreover, the method of making rice flowers was kept secret until the end of the novel.
