Suddenly, he thought of something, reached out to take the necklace, and carefully rubbed the oval pendant.
Soon after, his eyes flickered, and he discovered something. He slightly exerted force to open both sides of the pendant.
Everyone was surprised to find that the necklace actually concealed a secret mechanism.
"But inside, it's just a black gemstone, nothing special," the elder said, looking at the black gemstone inside the necklace, puzzled.
Lin Beichen frowned slightly at the black gemstone in the pendant. He always felt that the necklace wasn't that simple.
He lowered his gaze and tentatively rotated the black gemstone, only to discover that this gemstone could indeed be turned, and there was a rotating compartment at the back.
Even more coincidentally, the shape of this rotating compartment perfectly matched the miniature USB drive they had just acquired.
"Truly unexpected!"
Xia Luyao's exclamation echoed in the air.
