Special police officer Qin Ming encountered a sudden change in time and space while escorting supplies. He and his explosion-proof vehicle traveled to the Hongwu Dynasty Palace and were mistaken for an assassin on the spot. Facing the arrow rain encirclement and suppression by the Jinyi Guards and the Forbidden Army, he fought back with a Type 95 assault rifle, injuring thousands of people in one minute. In desperation, he took Princess Ning Guo hostage to protect herself. Armed with modern weapons, he faced the thunderous wrath of the founding emperor Zhu Yuanzhang.
