When modern people accidentally travel to the Demon Sect to take the entrance examination, how should they choose when faced with killing or being killed? Waiting online, it's quite urgent...
This is an imaginative fantasy magic novel. See how the protagonist uses the Soul Refining Flag to travel between the Yin and Yang worlds. It is an innovative fusion of scientific cultivation + underworld infrastructure + time and space paradox, and contains quantum mechanics and reincarnation philosophical metaphors throughout the book. I hope you will like it after reading the novel!
