And because of that, it was really better not to see the elders while they were in the process of rebuilding themselves.
See, upon learning the truth about the outside, Elder Shen decided to take immediate action. This, of course, scandalized the other elders who had been there far longer and prided themselves on not rushing into "foolish" decisions.
"What?! That many?!"
"Yes! With that many people, how much faith should there be to go around? And yet it seems like there are no working deities anywhere!"
"Have they all been slacking off?"
"Shhh! I'm thinking!" Elder Shen declared.
"Don't. It's never good when you do. At this rate, you might lose the last of your remaining sensibilities," Elder Feng shot back.
"Aish! This is why you've gone senile! Can't you see the problem here? With this many people and this many chances to acquire faith, do you really think no one would want to work?"
