Ling Han walked into the fog, and continued to search for the formation foundations.
Since he had already found two, finding the third one was naturally not a problem. Very quickly, Ling Han located it.
He dug seven feet into the ground, and obtained the third formation foundations.
"I can't dig anymore." Ling Han sighed. It wasn't that he didn't have enough time, but that the three formation foundations were already very obvious. They had stretched his clothes so much that the latter were nearly bursting at the seams, and thus it was impossible for him to hold a fourth one.
"I'll have to come back and dig for them later."
Ling Han was still thinking about it. This formation ought to be very high-level, being capable of forcibly bringing down the cultivation level of Meridian Opening Tier to almost the same level. It would also be very practical in battle.
