Chapter 651: Studying A Formation Board

"Formation board, formation board…"

As Ou Yangming mumbled, he quickly carved a peculiar ore into a round board.

After being ambushed and countering the ambush, he had a clearer understanding of formation boards.

Formation masters were a profession rarer than blacksmiths. Their biggest reliance was formation boards, where formation maps that were engraved inside had enormous powers that allowed weak parties to dominate and challenge opponents of higher ranks.

Although formation masters had notable powers that could turn everything around, their potency was the reason they were rare.

Ou Yangming had not met a real formation master in the lower realm. Elder Universe had only scratched the surface from numerous ancient manuals because he lived long enough and had sufficient knowledge.
