Xiao Zhaoyang, the general who ruled the country and was demoted to slavery, endured seven years in the hard labor camp in the imperial city and used blood as ink to recast the soul of the Xuanjia army. The sworn brother Shen Jiuyuan rises up step by step, but he holds the truth about his life and death; Su Mu, the master of medicine and poison, poisons day and night and saves people every night; blacksmith Zhao Tiegu melts armor and casts blades, and Liu Ruyan, the leader of Qingying, holds the evidence but says nothing. Within seven days, Xuan Jia's old men washed the palace gates with blood, their iron armor crushed the glazed tiles, and intrigue and betrayal clashed in the fire. Revenge is not the end, but the prologue to a new order.
