The German Butler in Douluo

Zhang Yu traveled through the Douluo Continent and had an innate soul power of level 0.1. Don't panic! The old version of Xin Zhao's skills help, plus ten years of experience as a dog-head bar owner. Every time his teammates played in a group, Zhang Yu would silently listen to his experience and occasionally go up to make a point, performing the word "gou" to the extreme. Certainly. Never leave Zhang Yu behind. Otherwise, there will be consequences at your own risk... Tang San: "..." Qian Renxue: "..." Ning Rongrong: "..." (Shu Huang, a fanfic written using the old version of Xin Zhao's skills as a combination)
