Li Cheng, a philosophy student, traveled through time and became Wang Xiazi, a down-and-out fortune teller in ancient times. With the help of modern logical thinking and knowledge of probability, he found a new path in a world full of metaphysical battles. After being forced into conflicts of ideas and interests with traditional Taoist forces such as the "Tianji Sect", he gradually came into contact with and deciphered the secret techniques of various schools, integrated the essence of Eastern and Western thoughts, and finally got a glimpse of the whole river of destiny. However, the closer he comes to "omniscientness", the deeper he falls into the dilemma of "irreversible" fatalism. In the end, he chose to destroy all the divination tools and retreat into the mountains and forests, leaving behind the legend that "he who has calculated all the secrets of heaven cannot change his destiny."
