Story of: Super time and space transaction, I exchanged half a bottle of water for an aircraft carrierZhang Yang returned home and inherited his father’s scrap shop. He suddenly activated the super-time and space trading system, which allowed him to trade with parallel worlds.Before 2018, this parallel world was no different from the blue planet where Zhang Yang lived.But in 2018, due to the crazy behavior of a biologist, the world directly turned into doomsday.Because of the constant teasing of doomsday, the world has long become extremely short of daily necessities.The aircraft carriers, fifth-generation fighter jets, lithography machines, etc. that once represented the pinnacle of industry have now become a pile of scrap metal, and their value is not even as good as a bottle of mineral water.Zhang Yang exchanged mineral water, instant noodles, and sausages for countless supplies.Aircraft carriers, fifth-generation fighters, lithography machines, five-axis machine tools or machining centers, etc.The high-tech and equipment that had been blocked before have become commonplace due to Zhang Yang’s continuous trading.
