Prompt: A literati dressed in ancient robes stands alone at the summit of Tianmushan, surrounded by ink-black clouds and mist. He gazes up at the vast sky, holding a brush in his hand, lost in contemplation. Below the mountain, there is a sea of boundless clouds, and distant peaks appear and disappear in the mist. The literati wears a melancholic expression, as if engaged in a dialogue with the mysterious forces of heaven and earth.
