Qin Yan, who lived alone in a dilapidated village in the mountains, had been living a stable life until one day a group of traders who came from nowhere wandered into his village. Qin Yan kindly took him in for one night and gave him a book of Qi training and a book of sword moves. After that, the child who had never been interested in the outside world became curious for the first time. So driven by curiosity, Qin Yan took the only scalper who accompanied him and set off to think about the outside world.
