My Supermarket Connects to the Seventies, and I Strike It Rich and Become a Favorite in Two Eras

[Dual transmigration + stockpiling goods and getting rich + period setting + face-slapping + sweet romance between two men + heartbreaking love and redemption] Deep in debt and out of options, Lin Wanwan takes over a 21st-century supermarket on the verge of bankruptcy. Then she discovers that the broken wooden door in its storeroom connects to a little shop in the 1970s! Even more incredible, the shop’s owner is her beloved grandmother, who raised her and had already passed away with regrets, back when she was young! She takes modern high-powered flashlights, pretty hair clips, and meat buns to the 1970s, trading them for rare stamps, vintage Maotai, and century-old wild ginseng, then sells them for astronomical prices in the modern era! Trading in both directions, she gets rich overnight! She doesn’t just humiliate villains and make her debt collectors kneel and call her their ancestor, she also begins a journey to save her grandmother’s fate. A powerful tycoon from the 21st century spends lavishly on her, pampering her with domineering sweetness. A roguishly handsome, rugged man from the 1970s treasures her and risks his life for her. When Lin Wanwan has made a fortune, she suddenly realizes that the impoverished yet passionate soul from that era has already become part of her very bones. But just as she decides to stay, the time-space doorway begins to collapse... When the door finally closes, what will become of a love that has crossed half a century?
