Siheyuan: From the Start, I Made the Goddess Crawl Through a Dog Door

(Courtyard setting + possibly one heroine + no System + making money) All he wants in this life is to make money. In 1995, instead of going to high school, he went to vocational school. In 1998, he learned how to repair big brother phones. At the end of 2003, he used every last bit of his own and his family's savings to open a pager shop. By 2012, he'd saved up quite a bit more. Thinking he couldn't open a store, he got into secondhand phones and bought up a lot of Nokias. In 2019, he opened a restaurant. His whole life, he'd kept right up with the times. He never expected to suddenly end up in a courtyard in the 1960s. He'd transmigrated way too early. And now a goddess was in his room, while the courtyard vultures outside were about to rush in and catch them. In his panic, he told the goddess to crawl through the dog hole. As for him, he was going to make money in this era too. First, he'd set himself a modest goal: earn 2,000 and call it quits.
