Heaven is in good health, and a gentleman strives to constantly strive for self-improvement. The terrain is kun, and a gentleman carries things with kindness. Zhou Yi and Dong Tiancheng had different origins and different families, but they traveled and fought together in the world. Fighting against the sky is endless fun. Fighting with the ground is endless fun. Fighting with others is endless fun. The title of this book, "auxiliary teeth", also comes from "the auxiliary teeth rely on each other".
