Once a cowherd boy of Yu, Shen Wudu obtained immortality from a divine jade after his kingdom’s ruin. He witnessed thirteen dynasties, inscribed steles for twelve emperors, and was Great Zhou’s imperial preceptor for six hundred years. New emperor Xiao Jing, fearing his immortality, imprisoned him for execution. When Northern Di attacked, Shen Wudu called forth twelve emperors’ souls to defeat the invaders. He met Mei Niang’s spirit, who had waited three hundred years for him, and she urged him to live on before vanishing. Shen Wudu helped Xiao Jing uncover moles and grow into a ruler. Xiao Jing vowed to be a sage king. Shen Wudu stayed to guard the land, and the three-thousand-year-old immortal finally found his purpose.
