Folklorist Lin Zhengyang traveled through time and became a blind and mute man (pretending) who made a living in the occupied areas of North China by reading Feng Shui. He inherited the family's secret "Shaking the Dragon Scripture" and found that it was not a superstition, but an ancient "all-terrain combat manual" that combined geography, hydrology, geology, and climate. He infiltrated the intelligence circle by showing the shady houses of wealthy villagers, tampering with terrain maps, inducing landslides, and using underground rivers to create fog. He used the sky and the earth as traps to allow the Japanese to step into the "natural killing array" he set up again and again, and waged the most incredible guerrilla warfare in the Taihang Mountains.
