Introduction to Baxian Lake: The water of Baxian Lake is extremely clear, and there is no trace of sludge at the bottom of the lake. Legend has it that one day after finishing her practice, the fairy girl was upset. Tieguai Li made some calculations and learned that the people around her had been suffering from drought for many years. So the two went to investigate the people's sentiments, and later accused the Dragon King of negligence. The Dragon King was so frightened that he sent his youngest daughter, Xiao Longnu, to follow the two immortals here, and the Eight Immortals Lake was created.
