During the Zhengde period, the eunuch party was in chaos and the government was in chaos. The West Factory was destroyed and its power remained, while the East Factory became authoritarian and arrogant. In the solitary smoke of the desert, the Salon Gate Inn was reborn after a catastrophe, and became a place between the rivers and lakes and the court - where knights hide their enemies, and eunuchs spread their nets. A "Secret Book of Border Town Defense" contains the secrets of border armaments and the plans of foreign trade. After the border guard Xie Canglan was killed, it fell like thunder in the desert, attracting the remnants of the East Factory and West Factory, and the righteous men from the rivers and lakes to compete.
The legend of the old Jianghu heroes has not faded away, but a new sword has emerged. The inn proprietress Su Jinghong hides a blood feud, and defectes to Lu Qingfeng from a thousand households in Xichang in search of redemption. The ignorant girl Xie Wanqing flees the world with her secret book. The wind and sand spread over not only the cornices of the inn, but also the bloody battlefield between good and evil. The so-called chivalry is never about being alone, but holding the sword in desperate situations, leaving light in the darkness, and using one's own power to eliminate injustice in the world and protect the mountains and rivers.
