Ling Chuxi had heard of an array board before. In fact, it was an extremely compressed array that could be used for both defense and attack. It had the same principle as the array techniques set up by the Golden elixir sect. However, the requirements to inscribe formation disks were extremely high. Without sufficient strength and understanding of formation techniques, it was impossible to create a formation disk, so it had long since been lost.
"What's this formation plate for?" Ling Chuxi asked curiously. She had a feeling that this formation disk wasn't as simple as it seemed. The reason why Ling Gusong stood up for the Cold Moon Palace must be because of this formation disk fragment.
