After Lao Chen tragically loses his wife, he becomes listless and depressed. His daughter, Little Ciba, treasures the Sichuan pepper cultivation logbook left behind by her late mother, and the little girl is naturally exceptionally sensitive to the scent of Sichuan peppers. Relying on this precious notebook and his daughter's careful help, Lao Chen picks up Nine-Leaf Qing Sichuan pepper cultivation once again. Along the path of cultivation, the villagers encounter a series of harassments from the merchant Liu Mazi, such as selling fake seedlings, sulfur-treated peppers, maliciously destroying water canals, and stealing pepper saplings. Lao Chen unites with the villagers to see through all of Liu Mazi's scheming; facing capital's one-sided aggressive contracts, everyone rallies together with one heart to establish a Sichuan pepper cultivation cooperative. Through everyone's joint efforts, the Nine-Leaf Qing Sichuan pepper industry in Xianfeng Town is successfully built into a provincial demonstration base.
