As we all know, the world is divided into four dimensions and countless parallel worlds. Shen Lanshu (the protagonist) can travel through different time and space, but those stories have a spiritual fit with Shen Lanshu, as if they have happened to him before.
The stories of different people one after another aroused his desire to explore, and the immersive feeling brought to him by those imaginary people and objects across latitudes and eras made him start to be afraid. In the last dream, he discovered about his true life experience. Maybe there are people in the world who do not exist, and maybe there are things created by other dimensions in the world.
Part One: Shen Lanshu returned to the period of immortals and demons, met his first immortal soul, witnessed the battles in the three realms and the love between emperors.
Intention: Is it Shen Lanshu, Xiao Yan or me?
