With the development of digital technology and the increasing demand for artistic aesthetics and spiritual fulfillment among the public, the quality of games and the demands of players have become increasingly high. For electronic games, especially RPG games, relying solely on digital technology is far from enough. The most important factor is the game's core - game story creation. Along the cliffs on both sides of the Left River in southwestern China, there is the world's largest rock art group discovered to date - the Left River Huashan rock painting culture landscape. Creating a digital game based on the story of love, growth, self-redemption, and inheritance against the backdrop of the Huashan rock painting culture is not only an interpretation of ancient primitive rock painting art using contemporary technological language, but also an integration of Huashan rock painting art into a new cultural form in the current era.This paper elaborates on the integration of the Left River Huashan rock painting culture with game themes, the creation of game characters and plot, the construction of game emotional contexts, and other aspects, which will contribute to a better inheritance of the historical stories, inner life values, and deep cultural roots of the Left River Huashan rock painting to future generations.
