The wandering fortune teller Su Wan was hunted by the Holy See of Light for accurately predicting the "fall of the Holy Son", but was accidentally brought back to the Holy City by the Holy Son Pei Linyuan himself. In the name of "verifying the authenticity of the prophecy," Pei Linyuan trapped Su Wan in the Holy See's Astrology Pavilion, but in fact he secretly used her to decipher the oracle fragments. During the cooperation, the two gradually discovered that all the prophecies pointed to the truth of the "Night of the God's Fall" a hundred years ago - Pei Linyuan's identity as the Holy Son was actually a lie tampered with by the divine blood, and Su Wan's astrology was actually related to the ancient star palace. When the conspiracy of the Cardinals of the Holy See was revealed and the Dark Moon Order took advantage of the situation, Pei Linyuan was willing to bear the reputation of "apostasy" to protect Su Wan. Su Wan used his fate as a guide to reverse the star trajectory, and finally revealed the intertwined star diagram of their fate in the place where the gods fell: It turns out that he is the remnant soul abandoned by the gods, and she is the last night watchman of the Star Palace. Only each other is the "variable" that rewrites the prophecy. The full text uses "the prophecy will come true" as the anchor point of the novel, and promotes the plot through more than 20 precise slaps in the face (predicting the villain's conspiracy/resolving the crisis/emotional progress). The sweet love line goes from "mutual use" to "two-way redemption", intertwined with sugar knives.
