Ma Liang is a mischievous child who loves drawing and lives in a village called "Baihua Village." One day, the peaceful life there is shattered by the thunderous roar of cannons. A greedy and ruthless general, holding the young emperor hostage, arrives at Baihua Village with the intention of driving away the villagers to excavate the gold mines underground. 　　A deity known as the Ink-Splashing Immortal senses that a calamity is about to befall Baihua Village and descends to the mortal world specifically to entrust Ma Liang with a magical brush, hoping that Ma Liang can use it to thwart the general's sinister plot. 　　After obtaining the magical brush, Ma Liang draws a group of companions to help him overcome difficulties and defend his hometown, such as a money tree, a cat, a mouse, and others. They become important members of the village, assisting the villagers in solving many problems—and, of course, causing plenty of laughter along the way. 　　Upon learning of the magical brush, the greedy general spares no effort to obtain it. Through deceit, he manages to take the brush from Ma Liang and plans to destroy Baihua Village. With the help of everyone, the brave Ma Liang successfully defends his home and defeats the general. Through this ordeal, he truly comprehends the usage and essence of the magical brush and grows as a person.
