Legend has it that a long time ago, our ancestors left a piece of jade seal and a sentence: "Whoever gets the jade seal will win the world." Later, this jade seal brought great disaster to the world and even the court, and everyone risked their lives to snatch it. So much so that the ancestors had to hide it, leaving only a map where it could be found, and it was divided into two parts and scattered around the world. (The above is all nonsense. In fact, this is a short article about a husband and wife looking for enemies together and traveling around the world.)
