A modern agriculture professor traveled through time and became a sick and orphan girl in a barren mountain village. He did not rely on golden fingers, but only relied on solid soil improvement, improved seed selection, crop rotation and interplanting and other techniques to rebuild terraced fields on the ruins. From planting with plant ash to prevent insects to fermenting straw to raise pigs, we use scientific farming to break the fate of relying on the weather and lead the villagers from chewing tree bark to becoming rich. The loyal dog hunter silently guards the place, and the warmth naturally rises in the quietness of the years. No cruelty, no scum, just a steady stream of smoke and smoke. Let's see how the heroine uses knowledge to turn a remote and remote place into a real paradise.
