It is good. When I picked it up I did not think it would be so easy to just keep reading it.
The story is exactly what I wanted from a dungeon type webnovel.
Characters are good but I wish we had more of them.
I dont think it's all that bad because heaven would want worshipers, gods and resources. This world has none of those. I think they would be curious about what happened and how they can benefit with that knowledge.
