In the era of "artificial intelligence +", AIGC image generating technology has opened up a new road for the inheritance and innovation of traditional culture with its digital creative benefits such as rich created content, ease of operation, and high efficiency. This paper proposes an innovative design process for traditional cultural image extraction, narrative scene creation and audience emotional awakening based on the AIDA model from the three dimensions of visual translation, spiritual communication and cultural experience, with the starting point of inheriting the "Courageous Sword Spirit", highlighting the regional characteristics of Shaoxing and satisfying the audience’s emotional needs. Using the historical tale of Goujian, King of Yue, sleeping on firewood and tasting gall as a backdrop, and the IP image design of “Yue Chenfeng” and “Yue Yaoji”as practice objects, this article investigates the creative logic of Midjourney in IP design. AIGC technology currently has a high degree of unpredictability, and thus confronts the difficulty of effectively conveying the industry's unique demands to the model. This research provides theoretical support and practical approaches for the inheritance and innovative growth of the "Courageous Sword Spirit" culture, as well as an essential reference for the creative transformation and innovative development of China’s outstanding traditional culture.
