"Embroidery Blade Jinghan" is set in the warlords' troubled times, telling the story of Lin Wanyue, the successor of Jiangnan Qianji Embroidery, and Xiao Mohan, the leader of the "shadow" secret guard, on their two-way redemption and the road to determine the world together. Lin Wanyue has an extraordinary appearance and is responsible for guarding the secret treasures of the previous dynasty. However, she is forced to get married by the careerist Ye Li (warlord Nie Canglang's minion). She is trapped in a water prison, and her mother dies tragically at the last moment to leave a way for her to survive. She had previously rescued Xiao Mohan who was being chased by Nie Canlang. In order to repay his kindness and family revenge, Xiao Mohan rescued Lin Wanyue and formed an alliance.
Lin Wanyue transformed into a "Blood Rakshasa" in the Dark Guard Pavilion, pretending to be a blind girl to collect intelligence, and drive a wedge between Ye Li and Nie Canlang. The two went through hardships to the Sky Thunder Altar and obtained the secret treasure. In the end, they joined forces to kill Ye Li and Nie Canlang, consolidated the separatist forces, and quelled the troubled times. Xiao Mohan became the leader of the warlords, and Lin Wanyue assisted him in rectifying order, appeasing the people, implementing policies that benefit the people, and ending the war. The two worked together to protect the peace of one side, and their hatred eventually turned into protection.
