On the day he was demoted to the frontier army, Shen Zhao detonated a pre-embedded artillery piece and blew open the south gate of the imperial city, shocking the whole court. He is not a traitor, but he wants to blow up this cannibalistic system. In the cold wind in the north, he joined forces with Su Yan, the widow of the former dynasty, and used the secret skills of ancestral firearms as blades to create a steel storm with the military mafia Zhao Chongde, the crazy craftsman Liu Sangeng, the Beidi witch Mu Qingwu, and the broken-arm veteran Chen Tieshan. When artillery is no longer just a weapon, but the fire of the new world, who cares who is the traitor?
After Shen Zhao bombed the city, he fled to the north and used Su Yan's beacon code to reopen the old armory. However, he was surrounded and suppressed by the elite "Smoke and Thunder Army" sent by Zhao Chongde. Liu Sangen used bone plates to calculate the location of the Dragon Vein veins, and Chen Tieshan fought to the death to help Shen Zhao cast the first continuous-firing bronze cannon. Mu Qingwu secretly taught the blood crystal bullet formula, which caused the gunpowder to resonate with witchcraft power, destroying the barrier of Beidi Temple and triggering civil strife among the Bian tribe. Shen Zhao gradually recruited the border troops and established the "Iron Fire Camp". However, Su Yan awakened the bloodline of the previous dynasty during the blood crystal bomb experiment and began to question whether revenge should involve more innocent people. Zhao Chongde activated the royal "Sky Fire Forbidden Weapon" and wanted to rebuild the Fire Dragon Cannon with the blood sacrifice of thousands of people. Liu San even protected Shen Zhao from death and carved the "Fire Spirit Sutra" into the core of the cannon before his death. Shen Zhao led his army back to attack the capital, but Su Yan tore up the secret edict on the eve of the city's destruction. It turned out that the late emperor had known about the corruption of the military industry and ordered her to kill the king and restart the military system when the artillery appeared. As the artillery roared, Shen Zhao tightened his grip on the breech and asked her: 'Are we blowing up the imperial city or the people's hearts? '
