Guide to Traveling Through the Song Dynasty

When Yang Hao, a modern military history researcher, was participating in the Southern Song Dynasty Cultural Exhibition at the Songcheng Scenic Area in Hangzhou, he touched a mysterious ancient sword and was electrocuted to coma while trying to save a child. I woke up and found myself in Lin'an City of the Southern Song Dynasty. I became Lu Yu (a fictional character), a young official who was demoted for petitioning against the Jin Dynasty. The time was just before Yue Fei was recalled in the eleventh year of Shaoxing (1141).
