A farm that breeds gods and demons

This is actually a translation of "Killing Grounds of Gods and Devils". It's pretty old, with the original release being in 2010. From what I can tell, it's also pretty good though still has some of the common cliches and issues of other novels.

im fine with the end, just feels lonely thinking about it.

Honesty, not bad. Feels very nostalgic to see this kind of novel again, it’s been such a long time. Oh how the style of web novels changed. It still feels a bit hard to read later on, but still pretty good. Has that olden apocalyptic feel.
