บท 669: Chapter 668: Clayton Zuck

"How do you use this ring? How do you open it?" Yusuf Zuck looked it over from left to right but couldn't see anything special about this ring. It just looked like a very ordinary one—not gold, not silver, not copper, not aluminum. He had no idea what material it was made from.

"About this... first, you must drop blood on it to claim ownership, and only after solidifying the pill can you open it," the Black Jiao said apologetically.

"You can only open it after solidifying the pill? Blood oath?" Yusuf Zuck was frustrated for a moment; he was still a long way from that stage.

"How big is the space inside? Can it hold a person?" Yusuf Zuck asked again.

"It's about three cubic meters. You cannot put people in it, as it cannot absorb anything with life."

"Three cubic meters?" Yusuf Zuck imagined it for a moment. Three cubic meters was quite large, even bigger than an ordinary small bedroom. You could put all sorts of things for eating and use inside.
