After Defeating the Demon Dragon, I Somehow Switched Bodies with Her

【Transformation (many) + Dragon Girl + Western Fantasy + Subverting Expectations + No System】 After more than thirty years in another world, Fang Yuan had become a powerful figure through his own hard work. But the evil dragon Scarlett wouldn't tolerate a powerful person near her territory who might pose a threat. In the end, Fang Yuan defeated the dragon without much trouble. As he prepared to collect the spoils, Scarlett suddenly used a secret technique, and the human and dragon swapped bodies. “Someone, carry the dragon into the territory! From now on, our territory will have a giant dragon as its guardian beast.” Fang Yuan curled his lips into a smile. Scarlett was utterly bewildered. “Scarlett, people want to kill the dragon. You understand what I'm getting at, right?” Fang Yuan beckoned to Scarlett with a finger. Scarlett bit her lip, then reluctantly sat beside Fang Yuan. Just then, Scarlett used a forbidden technique she'd once obtained by chance to contract Fang Yuan before he could act. She used another forbidden technique, turning Fang Yuan into a girl. “You really thought I hadn't read novels? Of course I'd keep a trump card up my sleeve. From now on, your name is Fang Yuanyuan. And I should thank you for giving me this dragon body with its terrifying potential.” Scarlett smiled scornfully.
