Immortals Duel in Cloud-Sea

Full Prompt

In a vast cloud-sea battlefield suspended above the nine heavens, the backdrop is a void interwoven with brilliant purple-gold auroras and starry rivers. Two originally designed fictional immortals are engaged in an intense magical duel. The immortal on the left, clad in flowing platinum battle armor and surrounded by complex golden rune halos, summons a massive phantom of a light dragon with a wave of his hand; his opponent on the right, draped in a deep ink-blue robe, commands thunder and black mist, with countless glowing energy flying swords suspended around him. This is a pure visual feast of energy and light and shadow.
