Li Yuzi, a little person who accidentally traveled to the world of "Love in the Courtyard", thought he had a hopeless start, but accidentally activated the "god-level waste recycling and upgrading system". This system can turn everything in the world into "recycling points" and unlock a variety of unimaginable upgrade options. From dilapidated radios to abandoned factory equipment, from trivial things in courtyard houses to the changing times, Li Yuzi will rely on the information and capabilities brought by the system to step by step turn "waste" into the cornerstone of his empire, and write his own legend in that magnificent era. His story will always revolve around courtyard houses, steel rolling mills and the social changes of that special era, and will eventually become a legend of the times that affects one party.
