During the Zhenguan period, undercurrents surged in the land of Longyou. Luo Zheng accidentally traveled through time and activated the mysterious military industry system. He originally wanted to benefit the people by improving farm tools and training soldiers in the fields, but he was involved in the whirlpool due to a bizarre workshop murder. The owner of the ironworks workshop was killed by a rare three-sided military assassin. The mysterious blood talisman and the weapon that transcended the times at the scene hinted at the involvement of unknown forces.
When interrogating craftsmen, the system keenly captures everyone's abnormal reactions. Luo Zheng cleverly used a differentiation strategy to learn from his apprentice that the workshop owner was killed because he refused to make prohibited weapons. As the investigation deepened, he discovered that the man behind the scenes was actually a mysterious caravan wearing a black veil, and taboo items such as gunpowder ratio charts appeared in the transaction list.
Above the court, the old ministers accused him of "conducting the public with sorcery"; outside the border, 200,000 Turkic cavalry were watching eagerly. Luo Zheng relied on the system to unlock advanced technology, improved blast furnace ironmaking, designed a repeating crossbow machine, and launched a technical duel with aristocratic swordsmiths in the Ordnance Department. When the Turks pressed the enemy, he pressed the wrist guard mechanism and used modern technology to rewrite the war situation. A contest between technology and conspiracy suddenly unfolded in the heyday of Zhenguan.
