This is a very lucrative niche project – the Chinese-style AI healing comic-copy play. Worry not about material: with 5,000 years of splendid civilization, there's enough material to write for several lifetimes. Just simple crafting, and any video or image-text piece can really shine.
E.g., draw on classical poetry like Li Qingzhao's work, or borrow web memes like "Lin Daiyu yanking down a willow." Once posted, such content has viral potential. In the AI age, making it is also quick and easy.
