A modern youth time-travels to become Jiang Chen, the wicked young master of Jiangzhou, binding with a furball system where he must study and do good deeds to extend his life. He diagnoses and treats people for free, improves agricultural tools, promotes potato crop rotation, carves poems and draws dragons at literary gatherings, and startles the scene with his exam questions in the autumn trials. From a prodigal reviled by everyone to a saint stirring up Jiangzhou, he protects those around him, breaks old rules, and walks all the way toward the top scholar and the imperial court.
