A 24-year-old delivery driver, whose father was seriously ill and owed 150,000 in debt, was mocked by his ex-girlfriend for being useless. During a delivery trip to the northwest, he accidentally stumbled into an abandoned mine cave and time-traveled with his truck to the northern border of ancient times. Female General Xiao Zheng guarded the city for five years, but was cut off from food supplies by the imperial court for three months, with 300,000 barbarians besieging the city and 8,000 remaining soldiers on the verge of despair. The instant noodles and ham sausages on Su Mingyuan's truck were treated as divine items by Xiao Zheng, who bought the entire truck for fifty taels of gold. From then on, he traveled back and forth between ancient and modern times, exchanging modern supplies for ancient treasures, going from heavily in debt to having a net worth of hundreds of millions. Searchlights repelled the barbarians, drones suppressed a 100,000-strong army, and bulldozers crushed Yanmen Pass, helping Xiao Zheng all the way to claim the throne as empress. Finally, the marriage proposal succeeded.
