Over the 2 thousand years, Ning had never bothered learning how to make formations or the formation flags. Creating a formation was never something he thought he required.
However, he did learn deconstruction of formations. He learned how to stop a formation, dismantle it, or if required, destroy it.
So, when he saw the shadows about to overlap and form a perfect formation on the pattern below, he quickly tossed a gold coin in it to open it.
Once the formation was filled, it lit up and opened what looked like a portal to a secret realm.
Ning stepped forward and disappeared. He felt a slight tug on his body as if he was being pulled down instead of teleporting.
"Hmm… interesting," he thought as he let his body free fall. It took him what felt like 3 minutes to finally reach the bottom with a bang. He only had to bend his knees slightly to absorb all of the force of the impact, however.
