At the end of the Wen Zhao Dynasty, Li Han, a poor scholar, innovated the art of war with the divine fire crossbow, and Zhao Wu, the fierce border general, used his iron-bone sword to control the north. The two worked together to end Wang Su's rebellion and established the founding legend of "the combination of sword and pen". Twenty years later, Li Yang took the first prize in high school with the improved Shenhuo Crossbow. Zhao Tian took the lead in martial arts and entered the Yulin Guards. However, he was involved in the arson case of Bailu Academy and the undercurrent of privately forged weapons in the military. With the remnants of the Peony League reappearing, two generations have uncovered the truth about the imperial examination fraud case twenty years ago - the cold iron sand of the Western Regions, the peony pattern secrets, and the ink and martial arts formations. The pens of the poor children and the swords of the frontier soldiers are once again intertwined. Amid the conspiracy of the gentry and the border crisis, a new chapter of "the rise of the poor and the sword and pen protecting the country" will continue to be written!
