The extreme grade spirit range landed on the sand and Xie Zhengshi threw out tens of formation flags, pinning it down.
Ye Mo set up a spirit providing formation on the spirit range first and then rapidly flew around the huge sand sinkhole, setting up formation flags.
When Xie Zhengshi saw that Ye Mo placed all the formation flags in the void, his eyes began to flicker. Of course he had heard of void formation flags, they were an extremely difficult means of setting up formations that he couldn't use yet.
It was already very shocking to know that Ye Mo was a level nine formation grandmaster, but he didn't expect Ye Mo to be able to set up void formation flags so smoothly. This formation skill was clearly near level nine peak. He really didn't understand how Ye Mo learned. He even wanted to ask how old Ye Mo was - was he an old monster who had lived millenniums?
