It was a Secret Treasure, alright, but not one that was easy to claim. Touching it, even if you didn't die, would likely cost you an arm. Forget those with Low Cultivation—even experts with high Cultivation would find it hard to tame. The most they could do was resist its power. As for actually controlling the Yulan Pearl and making it one's own, that was a task of immense difficulty.
No wonder when the Demon Fox Race was conquered, its people fled but left this Secret Treasure behind. It wasn't that they didn't have time to take it; it was that even they were incapable of moving the Yulan Pearl. So, it could only be left here, something to be seen but never touched.
