Jiang Zhuo travels to another world and binds the Dark Armor Deduction System. He gains experience and levels up by telling fortunes at a stall. He only wants a quiet life, yet keeps getting tangled in monster disasters, martial conflicts and court plots. He outwits the weasel demon, solves the red-haired xiao case, defeats martial artists, subdues boar demon forces, saves snake demon Bai Huiqing and takes in the fugitive master Xue Qinghan. Hiding his strength behind fortune-telling, he rises to the Martial Immortal realm. Even celestial officials come to recruit him, but he chooses to stay on earth and keep his stall.
