Lin Wan, 35 years old, is a core researcher of the national mysterious organization "Kunlun". He has been gifted since childhood and has studied metaphysics by himself. At the age of 25, he has reached the realm of Taoism. On her 35th birthday, she was struck by a lightning strike while watching "Huan Zhu Ge Ge" with Fang Yu, her best friend of twenty years. When she opened her eyes again, she became the "Little Swallow" of Huan Zhu Ge Ge who was making a scene in the imperial garden; Fang Yu became the empress Ulanara who was sitting on the phoenix throne with eyes full of hatred.
There are two sets of personalities coexisting in this little swallow's body: the original one is naive and reckless, and loves Yongqi as much as his life; the Taoist saint Lin Wan is calm and distant, and always wants to study the spiritual laws of this world. When Ziwei was hugging her and crying, she would suddenly point her finger and say, "Don't go out if there is a bloody disaster today." When Yongqi climbed over the wall to confess her love, she stared at the center of his eyebrows and said, "You have the Ziwei auxiliary star in your life. If you are willing to practice, you can extend your life for a hundred years." Everyone just thought she was crazy again.
What's even more dangerous is that there are real practitioners in this world. The "Mr. Mysterious" Zhao He from the Western Regions next to Concubine Gao turned out to be an evil cultivator in the late stage of foundation building. He used the "soul-drawing Gu" to steal Qianlong's dragon energy and used the resentful souls of border officers to practice evil arts in an attempt to completely control Chao Gang.
The only insider, Fang Yu, now the queen, set a secret code with her. One person would bring order to the harem, while the other would protect the front court. All the emotional lines of the original drama are retained: Yongqi is still crazy about her; Ziwei and Erkang are committed to each other life and death; Qing'er has a lifelong misunderstanding about Xiao Jian; Jin Suo is crazy about Liu Qing. It's just that at every important node, there is an extra "sometimes crazy, sometimes profound" little Yanzi who intervenes, turning Qiong Yao's crying and wiping away tears step by step into a shocking chess game intertwined by immortals and mortals.
