After transmigrating into the life of an impoverished migrant during the “Huguang fills Sichuan” migration, Chen Xu starts by improving a bowl of brown sugar. He brings the fragrance of sugar to barren fields, sets up cooperatives, takes on local tyrants, solves wrongful convictions, and earns an official post. Modern ideas take root in the Qing Dynasty as he makes sugar, boosts agriculture, writes books, and opens schools... Using his knowledge, he sweetens meals for countless families and warms the hearts of the people. This is a tale of struggle in another era, without a golden finger: only the sparks of knowledge put into practice, and a love that slowly grows warmer amid hard times.
