Su Yuan was originally a scholar in the market. He was obsessed with painting and had no idea about the path to immortality. However, there was a thunderstorm one night, and the picture in his dream transformed into a dragon, leading him into a bizarre world. There are no immortals or demons in this world, only the "curse of falling ink" that has not been solved for thousands of years circulates in the world - the fate of anyone drawn on paper is cut by the brush. Su Yuan claimed that he had no chance to cultivate, but he unintentionally used paintings as a guide to disturb the laws of heaven and earth. He not only wants to find his own destiny, but also witnesses the interplay of love and hate, and the changing colors of mountains and rivers in the paintings of all living beings. People in the world are fighting for the path to immortality and immortality, but Su Yuan uses ordinary pen and ink to outline a path home that is neither immortal nor extraordinary. When reality and fantasy intersect, he finally has to make a decision: should he go with the flow and let the curse pull his soul, or should he break the situation with painting and establish his destiny between heaven and earth?
