Tao Yi was once the eldest daughter of Tao Family Village, but due to various conflicts between her mother and father, she was kicked out of the house at the age of five. She worked as a killer for twelve years, but her last mission was to protect this family that she already hated. However, Mo Niqian stayed behind, and as his knife, he broke into the main city of Beiyan Mountain, which was full of mechanisms, and stole the blueprints, all for the sake of Mo Niqian's life.
When he was in Beiyan Mountain, he rescued Dong Mu who had been robbed of supplies. Later, he became one of Tao Yi's good friends and secretly helped Tao Yi steal various medicine bottles. Dong Mu is just a businessman, and his relationships are as intricate as a tree in the sky.
