"What is it?"
Claud stopped and watched as Kamron took out a small aged box from his arms and handed it over.
Claud opened the box and saw a bronze key inside.
The key was about the width of a finger, about 4 inches, and it was carved with intricate and ancient patterns.
Claud looked at Kamron in confusion.
Kamron said, "Mr. Allston, it can open an ancient secret chamber, which has a magical inheritance of medicine."
"An ancient secret chamber with a magical inheritance of medicine? Are you sure?"
"No."
Kamron shook his head. "It is just a rumor, because there are a total of 12 keys, in the hands of the Nine Superb Doctors and the three great families with a long inheritance of traditional medicine in Nebraska respectively. You can only know Inheritance Cave's whereabouts after gathering the 12 bronze keys. And those keys are necessary to open Inheritance Cave.
