"Classmates, what I'm about to say next is very important, it will be on the exam." White Rabbit waved the barbecue tongs like a teaching whip. "Different talents require different rune circuits for upgrading."

White Rabbit patted Qing Ling's shoulder. "For example, this student's talent is 'Metal', the type of rune is 'Element', so it requires the 'Element' rune circuit for upgrading. Unfortunately, our organization currently doesn't have the element rune circuit."

"Where can we get it?" Qing Ling asked.

"In this city, there are a total of twelve rune circuits, each one unique. However, they are not disposable. After using it once, you have to wait a few days before using it again."
