If these lunatics intend to sacrifice themselves, they either have to undergo two occasions of being favored, then be handpicked by the Demon Lord.
Or, after their faith has lasted for a certain number of years, they can choose to sacrifice themselves when they are about to die, thus their soul can go to the side of the Demon Lord.
Just because of these two already established 'rules'.
Therefore, when Chen Dengming suggested the idea of self-sacrifice, a group of incense believers found it hard to accept.
It was as if the faith they had always held firm was shattered, and orders were changing constantly.
If they rashly make a decision now, they will fear difficulties in returning their souls to the judgment of the Demon Lord and thus, understandably, internal strife has ensued.
Chen Dengming realized he had perhaps been too ambitious. If he didn't step back now, he risked overextending himself, so he decided to put the discussion off for now.
