Yanfei fan server, Engineering Plastics, gathering Genshin players around the Liyue legal adviser.
Engineering Plastics is a wryly named Genshin server built around Yanfei, Liyue's sharp-tongued legal adviser. Members talk pyro builds, team comps and general game chat, with the odd inside joke about the server's odd title. It is a focused character space with a sense of humour about itself.
