[Reborn + period setting + dad life + getting rich + everyday life] What's the most valuable thing in the twenty-first century? Talent! That was just as true in 1981. The cattle station's technicians can't cure a cow, but Shen Dong gets it back on its feet. When every other dairy cooperative produces second-grade milk, Shen Dong raises his straight to top grade. The cooperative's dairy factory has been shut down for ages, but Shen Dong's yogurt recipe gives it a new lease on life. Shen Dong proves that a talented person is always a rare commodity, no matter the era! Starting with the dairy factory and the very first bottle of yogurt, Shen Dong sets off on his path to getting rich first.
