A young man, Shi An, full of sincerity, regardless of life and death saves a trapped silver dragon guarding the ridge, and unexpectedly receives a moon-patterned gathering basin that can replenish supplies three times a day. The divine basin can add rice, grain, medicinal herbs, and ironware, enough to relieve the poverty of a barren year, but it also hides greedy troubles and the covetousness of others. Adhering to the principle of using it only when urgently needed and stopping when enough is used, Shi An does not profit from the treasure, using it every time to save the urgent and help the weak. He helps neighbors resolve village conflicts, leads villagers to work together to repair wells and build granaries to weather natural disasters, and even moves profit-seeking grain merchants to transform toward goodness. When everyone gradually learns to help and guard each other, the mystery of the priceless divine basin also quietly circulates, hiding the worldly truth of saving others and oneself.
