"Fantasy City of Mortals" adds soft science fiction as a condiment. The story of the play takes place on Earth in 2020. The Ice King Kaso is reincarnated as Feng Suo (played by Feng Shaofeng), a big shot in a technology company. In an accident, he opens the door to the Ice Clan and gradually recovers his abilities and memories of his previous life. At the same time, he meets Luo Luo (played by Zhang Yuqi), the reincarnation of his lover Li Luo, again, which leads to a gorgeous adventure related to past and present lives.
