Double-Passing Door: Reselling Two Worlds, Starting from the 1970S

[Double-passing door + The traitor gets rich + Treasure appraisal + Dimensionality reduction attack + Divine hero] The business failed and he was in debt worth millions. When Chen Dong was forced into a desperate situation, he accidentally discovered that the cellar of his old house led to 1975! In this era of scarce supplies, the windproof lighter he brought with him was regarded as a black technology in the military industry; A pack of White Rabbit toffee can make the village party secretary be treated as a guest of honor; A box of amoxicillin is even regarded as a life-saving medicine! And Chen Dong was shocked to find that this era is full of treasures: A dirty bowl for feeding pigs? That was a Ru kiln from the Song Dynasty, priceless! The old bachelor's chamber pot? That's the Xuande Furnace of the Ming Dynasty, with a starting price of 100 million! Scrap paper for table legs? That's an out-of-print **"Blue Army Mail"**, and you can exchange for an apartment in the capital! Chen Dong made a crazy move: exchanging modern cheap industrial products for the top national treasures of that era! Back in modern times, he backhandedly bought a Rolls-Royce, leaving his snobbish ex-girlfriend heartbroken; Top boss Qin Tianhe is willing to act as his thug in order to get a wild ginseng! "Mr. Chen, how many national treasures do you still have?" Chen Dong looked at the calligraphy and painting porcelain piled in the cellar, and smiled lightly: "It's not much, I'll just buy half the world."
