Time Traveler in the Golden Era

Li Xianren accidentally travels to the vibrant 1970s, activating the 'Time Travel System' to gain a personal space and a golden door, allowing free travel between the 1970s and 2025. He uses modern supplies and knowledge to improve his impoverished life, gradually accumulating wealth and connections. He punishes bullies, saves his family, opens a restaurant in the county town, collects antiques, and befriends various factions. Meanwhile, in 2025, he sells gold and antiques, establishes a company, and becomes a new business tycoon. Li Xianren strategically operates between the two eras, gradually reaching the peak of his life across time and space.
