Master Li becomes suspicious about the fragment and discovers that it is actually real and that the 'mistakes' are actually clues, such as the number of a dragon's scales (146, actually 153), the number of points in acupuncture (253, actually about 360) and so on. The decoded message reveals the location of the Stone. Master Li also reveals the mummy in Liu Sheng's tomb had the wrong color wrappings, imperial yellow instead of mourning white, meaning that the mummy was not that of Liu Sheng.
