Modern calligraphy student Lin Zhao accidentally transmigrates into Gu Yan, the ailing young marshal of the Northern Border, and activates the Calligraphy System—writing letters that carry people's obsessions allows him to cultivate qi and heal his body. His father's old ruler hides a thin sword named "Taiping"! He writes a letter for a widow longing for her son, a letter for a soldier missing his wife, a letter for a girl seeking revenge for her massacred family… Each letter unlocks others' knots and strengthens his qi. When the final "Taiping Letter" is finished, the Five Elements Essences merge, curing Gu Yan's chronic illness! But then the Northern Border is invaded. Holding the Taiping Sword, with everyone he's comforted behind him—this time, he'll guard their peace!
