Shen Qingci, the retired number-one swordsman beneath heaven, is forced back into the jianghu. Amid conspiracies, mysteries surrounding his origins, clashes between good and evil, and matters of the heart, he explores the deeper meaning of “the greatest heroes fight for their country and its people.” As he faces choices between the turbulent jianghu and the greater good of his homeland, he embodies the chivalrous spirit that “a sword may be laid aside, but the heart must never grow cold.”
