Global Survival: A Wolf from the Start

Looking for Survival-for-All Stories Where the Protagonist Focuses on Building a Shelter and Isn't a Doormat

The protagonist shouldn't be a goody-goody, and there should be no female lead. I'd like someone dark-hearted, more like a villain, with plenty of descriptions of their shelter. Puppets would be a plus.

Wilderness Survival with a System, Tames a Bear from the Start

Apocalypse Survival Stories with Two Male Leads

Please, there are far too few stories with two male protagonists in the nationwide survival genre. I cannot find this type at all. Please do not recommend random books. Last time I asked, people recommended urban romance to me.

Looking for Survival Stories Where Everyone Takes Part

Harem novels only, please. No messy data, and the protagonist must be smart. Having a System would be even better, such as Delta Force or other treasure-hunting games with nationwide participation.

Looking for Apocalypse Survival or Online Game Stories with No Female Lead, No Female Lead

Looking for books similar to Apocalypse Arrives: A Hundredfold Drop Rate, Every Slash Drops Loot (Apocalypse Disaster Game). I'm looking for similar online game novels, with no female lead. Ideally, there should be lots of System-wide announcements. Apocalypse settings or everyone transmigrating are both fine. I'm not picky, as long as there's no female lead.
