In the Great Yan Dynasty, being a foot soldier is tough. Being a foot soldier who wants to keep himself and a pretty girl alive is even tougher. Lu Yuan doesn’t cultivate immortality or brew elixirs. He believes only in the umbrella in his hand and the sand in his pocket. This is the inspirational, and decidedly irreverent, tale of a perverted tactical genius and his three “problem teammates” as they survive in the Mountain and Sea Realm by skinning monsters, pulling out their sinews, upgrading their gear, and ultimately taking down the Demon King.
