It tells the story of a thousand-year-old snake named Wanwan who went to the Monster Management Bureau with a "Good Demon Certificate", but caused a sensation because the truth was too huge (it claimed to be able to circle the Forbidden City twice). The most shocking thing was that the mysterious and cold director of the Demon Management Bureau, Ling Yushen, rushed out in person, grabbed her wrist, and accused her of "cheating" away from his original demon pearl two thousand years ago. A fantasy love story that began in the Qin Dynasty and spanned thousands of years, full of "collision", oolongs and sweet bonds, unfolded hilariously in the modern city.
