A Prison

"There are still two transcendent-level experts suppressed in Maknum," the golden flood dragon said hesitantly. "If we join forces, Indiana Ibbot and the giant race will be nothing to us."

"Maknum is not that easy to break through!"

Out of the four locations, Maknum was probably the most mysterious.

Maknum had long been famous during the heyday of the immortal realm. 

Ordinary transcendents didn't dare venture there, and even now, the killing intent within could still trap them.
