Etiquette Is a Weapon

In the 14th year of Orthodoxy, the Tumubao Incident and the blood sacrifice of 100,000 Ming troops opened the door to the endless hell. The Four Hundred Years' War transformed the Ming Empire into a ruthless war machine. There is no holy light here, only thunder and fire guns consecrated with cinnabar and "Song of Righteousness". There are no angels here, only heavenly masters who sacrifice their senses to heaven in exchange for divine power. The only belief here is to engrave the word "loyalty and filial piety" on ammunition and blast it at the enemy. But when you find that the Gong Gong princes in the DPRK have betrayed "loyalty", and the soldiers on the front line who died for their comrades were killed by hidden arrows from their own people, can the gun in your hand still be fired? A low-level auxiliary soldier from the Shenji Battalion, an ancient three-eyed gun that houses the remnant soul of a thousand-year-old murderer, and a death row prisoner who defected from the Reincarnation Department just to find his name. The fate of the three people intersected in front of a secret letter of treason that could shake the country. What they are about to uncover is a truth darker than hell. Their journey will determine whether this eight-hundred-year-old war will ultimately lead to "purdue" or "resistance." When etiquette becomes ammunition, when loyalty and filial piety need to be verified. Only mortal blood still has warmth.
