Are there any invincible bloody novels that are suitable for collection?

In a harem novel, the wording must be especially good. Each person is limited to five. (Female Primogenitor or Rotten, Light Fictions, Horror, Fantasy, Wuxia, Sci-fi, Mecha Wars, Time Travel, Europe, America, Japan, Korea, Sense, Post-90s, Brainless)
(What is a male harem? At least 4-5 of them would be considered a harem.
For example, having three wives and four concubines, or Caiyun Kingdom Monogatari, how come life is not like a dream.
What I despise the most is a long list of copied and pasted words, and they are all written blindly. Please review the questions carefully. Everyone is limited to pushing five books.
And I also emphasized that you have to be good at writing. At the very least, you have to look at the standard of the examples I wrote before you answer.
Furthermore, it was a male harem, not a female harem.
If he could forget, it meant that the writing was not good. I dare not say that I have to write it like an ancient tree, but at least it should be memorable, thought-provoking, meaningful, interesting, and unique, right?
I realized that there are quite a few people who can't differentiate between men and women. What's a male harem? It was a harem made up of men! A group of country bumpkins, country bumpkins who knew neither rot, otaku, nor lily. He only knew H all day long. He was short-sighted. Strong disdain. If you don't understand the cuteness of a boy, or the charm of a natural, arrogant, and crossdresser, then don't answer. It was really infuriating. He didn't ask about anything very niche, but he actually got it wrong.

Answer 1

I recommend "Doomsday Collection Maniac". This sci-fi-doomsday crisis novel is very suitable for you! The protagonist was the Song family. They suddenly learned that the apocalypse was coming and began to collect all kinds of resources in order to survive. The main character, in order to become an invincible collector, did his best. This novel is very bloody, violent, and full of excitement. If you like bloody and violent novels, this book will be a hit! I hope you like this fairy's recommendation. Muah ~😗
