When Lin Feng traveled through time, his soul was bound to a mysterious "time and space beacon" that allowed him to physically travel between "now" and "ten thousand years later". The spiritual energy is abundant, there are many sects, and the cultivation civilization is at its peak. The protagonist Lin Feng has just entered the Qi refining period and cherishes the dream of eternal life and freedom. This is the starting point of the story and the "why" that needs to be changed. The spiritual energy of heaven and earth is inexplicably exhausted, and the path to spiritual practice is cut off. The former civilization of cultivating immortals was transformed into a "civilization of psychic technology". Each major sect has become a "research institute" (for example: Tianjian Sect → High Energy Particle Sword Equipment Research Institute; Danxia Sect → Biogene and Life Continuation Research Institute). They used scientific methods to analyze, utilize and store the remaining spiritual energy with great difficulty to deal with an unknown threat called "the end of entropy".
