In the eighth year of Yongming Dynasty, the Southern Qi Dynasty was on the verge of chaos.
Lin Yuan, a doctor of modern classical literature and religious studies, woke up in a pool of blood on the border of Jingzhou. With no identity, no memory, no supplies, and all his companions dead, he was regarded as a "Northern Spy Demon" by the Southern Qi garrison and faced the danger of being cut in half.
Zero cheats, zero systems, zero modern technology.
The only thing he has is the full text of "Tao Zang", folk taboos, the origin of talismans, yin and yang and five elements, Bu Gang, Tao Dou and Shang Qing Zhen Dharma that have been immersed in his mind for twenty years.
Starting from the deadlock in Jingzhou, he was forced to "pretend to be a heavenly master", using authentic Taoism to draw talismans to suppress ghosts, Bu Gang to detect fakes, and quoted scriptures to fight with Confucians and monks. Step by step, he proved his identity, resolved his karmic debts, and got involved in the whirlpool of family talk, Buddhism and Taoism, and the royal family's secret chess.
