The artist assumes that everyone who comes across this one has already finished reading the novel, so it doesn't matter how much messed up the story is, people will still understand what is going on.
There are two different parts of the story in this chapter. The fist (god-killing scene) is explained at the middle of the novel; while the second scene (Raven12345 looks for someone to help her getting end-of-the-year rewards) is nowhere to be found in the main story.
This is a pretty interesting novel, so I suggest you should give it a go before returning to the manhua version.
