During the Wanli period, murderous intent was hidden in the prison. Jin Yiwei Zhao Mang relied on the black iron magnet protective gear and the special Qi family sword to start a deadly battle with the White Lotus Demon Monk who carried strange poisonous insects and hidden nano-iron beads. The compound eye of the Gu insect hides a secret military aircraft map. Under the demon monk's skin is a strange body embedded with metal circuits, which involves Li Chengliang's shocking conspiracy of smuggling arms in his private mine. Zhao Mang used sonic resonance and magnetic field control to break the situation, and unexpectedly revealed the fatal hidden danger of the quenching defect of the Folan cannon, as well as the "Renchen" prophecy code related to the Battle of Saarhu twenty years later.
