"Well, well! At such a young age, you've already learned nothing good and started deceiving people, huh? The key was fake all along! I questioned those elders I caught, and none of them had ever seen this thing! There's no need to test it! Luckily, I sent the old dragon to track you just in case. Otherwise, you really might have slipped away!" Luo Dongjun flew over, his expression extremely grim.
I was surprised that he had realized so quickly, and that he had silently used the Thunder Dragon to track us for so long. But when I saw the face identical to Luo Shanyang's, I grew excited instead. Hadn't the solution just delivered itself to my door? So I immediately said, "Senior Luo, don't put it that way. I've never seen what this key is supposed to look like either. Why don't you tell me yourself—was the string I gave you a key or not?"

After all, it even had buttons. The silver key strip could extend and retract freely, and it had been cast as one piece, without even a trace of polishing. Its craftsmanship was truly conscientious.
"This... is indeed a delicate key, though I don't know what sort of treasure it opens. But it absolutely isn't the key to the Carefree Immortal Valley! You deceived me after all!" Although Luo Dongjun hesitated, he still believed that I had tricked him.
"This thing was left behind by Luo Shanyang. It just wasn't the only one. There was another key to the treasure chamber on this island, while you wanted the key to the Carefree Immortal Valley's treasure
