An elderly couple, Li Laotou and his wife, are over fifty, and their granddaughter, Xiao Hua, is seriously ill. While risking his life to gather medicinal herbs, Li Laotou rescues a mother qilin and her baby from danger. To save the gravely wounded adult qilin, he resolutely gives up the spiritual medicine that could save his granddaughter's life. Grateful for his kindness, the adult qilin offers its horn, which transforms into a blessed field, establishing a rule that seven parts may be taken while three must be left behind. Divine rice saves Xiao Hua, allowing the Li family to finally have enough food and clothing. Greedy grain merchant Qian Youcai covets the blessed field's harvest. He steals grain and falsifies the accounts, hoping to seize the Li family's home and farmland. Li Laotou finds the original account book and joins forces with the villagers to expose the fraud. Unafraid of threats, everyone works together to reclaim wasteland and build roads, making a living through their own hard work. In the end, Xiao Hua grows up safe and sound. Those who remain kind and true to their principles are rewarded after enduring hardship, while the greedy suffer the consequences of their own actions.
