The Burial Classics school originated in the Eastern Jin dynasty and flourished during the Ming and Qing dynasties. When Emperor Yongle of the Ming dynasty had the Forbidden City built, he summoned the era's foremost master of feng shui and geomancy, Kuai Xiang, to assess the terrain. Kuai Xiang belonged to the Burial Classics school. There is a saying: Southern Mao, Northern Ma, and the Burial Classics in the middle. After the fall of the Qing dynasty, a Taoist broke the fortune of the Burial Classics, feng shui, spirit mediums, and even Nanyang Gu arts and curses all at once. This caused the great masters of various schools to fall one after another, leaving their lineages in decline. Only the Three Pure Ones were upheld as orthodox; all others were relegated to the lesser schools. By a twist of fate, the young Zhao Ji, who had pledged his life to the underworld, became the last coffin-burier and yin-yang intermediary. He divines the future for the heavens, averts misfortune for people, guides ghosts across, and eradicates evil. He uses feng shui formations to break curses and burial arts to suppress a hundred evils.
