After deciding to explore the mysterious underground city, Merlin laid down rules that covered an area of ten meters, creating a formation.
Maiar watched his master's action from start to finish. With his astute eyes and wit, he was able to understand part of the rules that he saw.
Maiar secretly memorized the method of creating a formation.
Even though he was not proficient in fighting and spirit-forging, when it came to the alphabets and rules, he had amazing gifts.
Merlin laid rules in the surrounding rocks on the ground, forming a formation’s network.
This formation emitted a faint light; it gradually glowed brighter until it became a multitude of light strands weaving together.
Strange waves rippled out in layers.
A moment later, a black hole that penetrated deep into the ground appeared in the middle of the formation. But this piercing did not really exist. It was like a virtual illusion.
