"This thing is not light, what's it used for?" Zhou Leng examined it carefully.
The turtle shell was a mix of black, gray, and amber, the plates arranged neatly and carved with complex blue patterns, clearly containing some strange power within.
Azure Sword explained, "This is the 'Turtle Lock' of our Sea Demon Race. We have a habit of hiding important treasures on underwater islands and set up a gate for this purpose. If forced open by violent means, the entire treasure will explode. Only by carrying this kind of Turtle Lock can it be safely unlocked. This is the Turtle Lock of the Azure Royal Family; only if the royal bloodline is pure enough, will the position of the treasure appear when blood is dripped on it."
"And then?"
"I'll pawn this Turtle Lock to you; as long as we complete a cooperation, this treasure will be yours."
