Looking at the Great Plague Divine Eye in Daoist Banhai's hand, Chen Luoyang quickly understood.
The treasure in his hand was a part of the remaining power crystal of the Great Plague, or rather, an eyeball of the Netherworld God.
And right now, in Tianfeng City, it was very likely that the real Netherworld God's 'great plague' was happening.
If it was just another part of the crystallization of power, then it would be difficult for anyone in the sealed city to display it to this extent. Perhaps only Cheng Shuzhi and Wei Ling could do it, but there was no reason for these two to do so.
Either there were other experts sneaking in, or the real Netherworld God, the Great Plague, was hiding in Tianfeng City and had finally been exposed.
Chen Luoyang didn't have the time to investigate whether the other party had reacted because of his Plague Divine Eye or because of other reasons.
