Savage Mates: Rise of the Beast Queen

Botanist Lyra transmigrates into a savage beast world as a despised reject abandoned by six top alphas, thrown into death valley. Using her plant science and first aid, she heals a venomous lord, saves a spirit fox, exposes a princess's schemes, uses modern tech to turn wasteland into farmland, and awakens an ancient dragon. The six alphas fall for her one by one. When the empire attacks, she leads steam cavalry to crush the capital. When the creator judges, she fights gods.
