With a three-million-yuan loan coming due and his mother urgently needing surgery for kidney failure, Lin Fengshou is at the end of his rope when he unexpectedly discovers that the old water vat in his home can connect to ancient times! Across the connection, Li Family Village has suffered three months of severe drought, leaving no harvest, while unscrupulous grain merchants exploit the crisis by raising prices. Using modern supplies and agricultural technology to control events from afar, he crushes the corrupt merchants by selling rice for just five coins, astonishes the imperial court by raising ducks to eliminate locusts, and grows a thousand catties of rice on saline-alkali land. With just one water vat, he feeds an entire dynasty and completely rewrites his own destiny.
