Ji Shu, the deputy chief physician of the Rehabilitation Department of Wangjing Hospital, was 36 years old. He was tired and read a novel about cultivating immortals. He accidentally traveled through time and became Xu Qingran, a girl with heaven-level star spiritual roots in Lingxiao Immortal Platform. Another modern person, Gu Ye, traveled through the world at the same time. The two of them relied on modern thinking and their own advantages to counterattack in the world of immortality. They grew from newcomers to the immortal sect to strong men who can stand alone. They work together to explore secret realms, refine elixirs, and overcome difficulties. Ji Shu uses the combination of traditional Chinese and Western medicine to create a unique way of treating diseases in the world of immortality. On the way, they experienced tribulations in the human world and saw through the warmth and coldness of the world; they encountered a war in the six realms, and fought side by side against foreign enemies. They shared life and death. The two had already become each other's most solid support. Their love gradually grew, and they decided to give up the modern world and stay together in the world of fairy tales. But just when the dust had settled and they were enjoying the warmth of cultivating immortals, an inexplicable force swept over them, and the two of them were instantly pulled back to modern times. When the familiar hospitals and apartments reappear in front of us, is the side-by-side and guardianship during those years of cultivating immortality a hearty dream, or a real bond that spans time and space?
