He took out one very simple-looking map.
It was a map painted by Xiao Jin.
Before the New Year, Gu Chaoyan asked Xiao Jin to pay a visit to the Feather Mulberry Land, where he was supposed to get a good knowledge of the 15 towns in the Feather Mulberry Land. Xiao Jin directly gathered the information about each town and got a simple-looking map painted, so that the important spots as well as restaurants were all marked.
Although what Xiao Jin did was to get a map of the 15 towns, Sword Three, who kept him company, was inspired. He made a complete map about the Feather Mulberry Land and the Saint Divine Land as well as what he had learned about the places on their way back.
With Sword Three's map in hand, Zhou Huaijin believed that he had recieved a piece of treasure.
