Taking the dreamland of Ye Luoli's fairyland dream princess as the main line, it tells the story of the thousand-year ups and downs of Ye Luoli's fairy Bai Guangying and the thunder and lightning master Pang Zun, revealing the past and present life of Ye Luoli's world. In "Elf Dream Ye Luoli", the light fairy Bai Guangying and the thunder and lightning master Pang Zun once concluded a contract. For Thunder Lord Pang Zun, the light power of Fairy Light is his strongest source of power. The power of natural light is pure and endless, and the combination of light and electricity is a match made in heaven. However, there is something more important than power in Fairy Light's heart, and that is free will. The one who can truly conclude a contract with Fairy Light must be the person who can preserve her free will.
