Wanjie Supermarket, After Handing over the System, the Country Took Off

[Time Travel + Life and Death Gambling + Turn-in System + Powerful Country Racing + Hardcore Trading in Ten Thousand Realms] When Jiang Qing was taking inventory in the supermarket, she was stunned by the mechanical sound in her head: [The Wanjie Trading System was activated, first penetrated the Chu-Han battlefield, completed transactions with 15 people within 24 hours, and was stranded for 96 hours after failure]. The next second, the entire supermarket teleported, including people and shelves - she became a trader carrying a "mobile safe zone" into desperate situations. The mineral water on the shelf was a life-saving charm, antibiotics were hard currency, and the price of failure was never returning to another dimension. In the Chu-Han battlefield, she yelled "free treatment" to the refugees to get the number of transactions; in the world of immortality, she relied on hand-drawn spiritual vein maps to force back the barrier monks; in the interstellar refugee ship, she used electromagnetic pulsers to tear apart racial barriers in exchange for purifying spores; in the apocalyptic nuclear wasteland, she used improved seeds to allow female scavengers to trade independently for the first time; in the primitive beast world, she risked her life to save the snake tribe in exchange for moonstones, directly helping the country open the door to controllable nuclear fusion... Every journey through time travel is a gamble of life and death: the penalty for failure ranges from double detention to permanent death. Excessive radiation, flying swords to smash doors, and laser guns to break glass are commonplace. When she called the police with bloody pieces of silver and handed over the entire system to the country, no one expected that this decision would make Blue Star Technology take off in a straight line - nuclear wastewater treatment technology had breakthroughs due to interstellar spores, interstellar navigation data was decoded from mechanical chips, and even gender equality research relied on apocalyptic records to achieve breakthroughs. The number of products on the shelves is decreasing, but the country's technology tree is growing like crazy. Jiang Qing wiped the laser scorch marks on the supermarket glass and smiled while looking at the technological breakthrough report sent by the Communications Department: "This bet is won. The next stop will continue to make the world better."
