At first, the leaders of the organizations, like the ninth prince, brought millions and tens of millions of thunderstones to exchange at the thunder castle! This wasn't weird.... however, later on, since those with thunderstones have already exchanged them a long time ago, barely any large transactions appear.
"Lord Wu, here are 9.02 million thunderstones" with a flip of his hand, a spatial storage ring appeared.
The fat, white bearded old man extended his hand to take it. With a quick check, he couldn't help but to raise his head towards Luo Feng: "Kiddo, you surprise me more and more. It seems like you don't have that much authority in the alliance. With your previous exchanges, the total amount of thunderstones you used exceeds 10 million"
"Luck," Luo Feng smiled.
"Luck can't explain some things," the white bearded old man smiled and stopped talking there.
