Introduction: A modern young man travels through the Qin Dynasty and merges with the world of high martial arts and Qin. He is accepted as a disciple by Bei Mingzi, awakens the Qin national destiny system, and possesses the top immortal cultivation techniques and pills. He went into seclusion in Wuya Mountain Cave to trigger thirty-six purple thunder tribulations. He safely passed through the tribulation and broke through the foundation building, holding the self-refining spiritual weapon Dragon Shadow Sword. The leader Xiaomeng was reluctant to give up, and wanted to give the Qiuli Sword as a gift but was declined. Li Yaofeng saw through the great Qin's external power and internal cadres, and the undercurrents of various forces. He took the sword to bid farewell to Xiaomeng and went down the mountain to join the world, using the national destiny system to calm the troubled times.
