Curse Tribe Versus Heaven-earth Grand Curse, Heavenly Curse Forefather, The Forefather Is A Fake?

"T-This is the Heaven-earth Grand Curse!" 

Xue Tianjun instantly recognized the curse that enveloped the Curse Tribe.

It was the Heaven-earth Grand Curse from the Divine Curse Seal.

Xue Huo once showed it to him before!

"Impossible! Xue Huo is dead! Who else knows this curse technique? Hold on…" A sudden realization struck Xue Tianjun, and his eyes widened in fear.

Not only him but the other Monarchs had the same realization as well.

Xue Huo was indeed dead, but he died in the hands of Chu Kuangren, which means the Divine Curse Seal might be in Chu Kuangren's possession.

If there was another person who knew the Heaven-earth Grand Curse, it must be Chu Kuangren.

On top of that, the Curse Tribe had just failed to curse Chu Kuangren and were still suffering the repercussions when the Heaven-earth Grand Curse came after them. 

If not Chu Kuangren, who else?
