Sirens originate from ancient Greek mythology, where she is depicted as a sea creature with a human face and bird's body, soaring over the ocean. Possessing a heavenly voice, she often lures passing sailors with her songs, causing their ships to crash and sink, while the crew becomes her prey. Inspired by the legend of the sea siren, the Siren High-Tech Company, with ulterior motives, launched the "Magic Sound Project." They built a TEM high-frequency sound wave transmission tower on an uninhabited island in Southeast Asia and selected singers from around the world whose voices closely matched the "magic sound." Using a high-tech system, they transformed these singers into "magic singers," intending to control sailors and carry out a pirate plan. The Siren Company came to China to select magic singers, and Xiaomi, a close friend of a student named Liu Wanxin, was chosen. To save her friend, Liu Wanxin discovered clues about the "Pure Sound Bronze Drum," capable of defeating the magic sound, in an ancient Zhuang village. Determined to find the lost Pure Sound Bronze Drum in the ASEAN region, Liu Wanxin bravely embarked on a perilous adventure, despite the Siren Company's attempts to stop and pursue her. During her search, she formed deep bonds with Vietnamese teenager Wu Shijia, Thai girl Mulail, and Cambodian teenager Suolang Gong. With Suolang Gong's help, Liu Wanxin found the lost Zhuang Pure Sound Bronze Drum in a sacred Cambodian site. With the assistance of awakened Siren Company personnel, Liu Wanxin and her friends from ASEAN countries ultimately triumphed over the magic sound on the uninhabited island, saving her friend in an inspiring tale.
