He hadn't paid much attention to it back then. After all, this was only a small peculiarity, but it now seemed that these mana crystals should be the key to opening the stone door.
Directly in front of the stone door was a space of the same size, 66 meters, with a circular pattern. It was divided into three parts, and each one had ten round stone platforms, for a total of thirty.
Lin Yun inwardly nodded. He had confirmed that the mana crystals were keys and that those stone platforms were the teleportation points. In other words, regardless of where this led, only thirty people could pass through when it was activated.
Each section of the stone door had thirty-six openings. In other words, one hundred and eight mana crystals were needed to activate this ancient array.
He had twenty in his pocket, which was naturally insufficient.
Lin Yun waited there, convinced that the other forces would definitely arrive quickly.
