The two daughters adopted by the leader of the Elf World are a strange pair. The younger sister is lively and talented, surpassing her peers at a young age; while the elder sister is silent and less capable than a three-year-old child. The elves in Yunqi Jiuzhou all face two choices when they reach adulthood. One is to stay in the elven world and serve the elves, and the other is to conclude a contract with humans and become their helper. However, only a very small number of elves surrender to humans. In order to prevent herself from becoming her sister's weakness, her sister Fang Fang resolutely went to the human world to find a way to become stronger and become a helper for mankind. But things didn't seem to be as simple as she imagined. The preoccupied human contractor, the enemies who are chasing him and his sister, the companions who behave strangely, and his innate energy that repels his sister, all of them invariably declare that the optical fiber is unusual. Fiber Optic: "What would you do if... You found out that I'm not your sister?" Guangying: "No matter what happens, you will always be my dearest sister! The bond between us is stronger than light! Who said this? I'm going to kill him."
