Duncan looked at the defensive formation that was activated completely in front of him and twitched his lips.
Sure enough, any clan with centuries of accumulation couldn't be taken easily. For a clan like the Wang Clan, having middle-tier second-level defensive formation could be said to be not bad.
However, the formation in front of him was a high-tier second-level defensive formation. Formations were also divided into grades. Each level corresponds to an equivalent cultivation level. They are further divided into four grades – low, middle, high, and top.
With each grade, the power of the formation differs at each level. Low-tier formation corresponds to the lower end of the corresponding cultivation level and top-tier means the strength of perfection in the corresponding cultivation level. It was lucky that the Wang Clan didn't have a top-tier defensive formation.
That would have made things tricky.
