After experiencing just how corrupt and exorbitant the Assassin's Guild was, Yan Xing began devising a way to enter the game himself. However, Nuta City's Assassin's Guild had been operating for so long that it possessed an extremely solid foundation, making it difficult to simply step in. It required meticulous planning. Taking inspiration from online e-commerce platforms, Yan Xing designed his own Assassin's Guild platform. By incorporating membership and ranking levels, he then developed the blueprint for the 'Creed' Assassin's Guild.
