Who's asking? Why do you want to know?
Yeah, that's a nope. I read rebirth novels because I prefer protagonists that actually have a clue about what they're doing. Old guy in his head that's actually future him is not the same as being an old guy, and I definitely prefer the latter. Probably not going to read this one.
Yeah, I totally agree that this is fairly well done overall. If kingdom building is your thing, it's pretty great even. It's just that I felt like people should know what they're getting into here, since the summary, premise, and first chapters are kind of misleading.
For those of you who, like me, expected this survival expert character to actually follow through on his background and do things at all related to solo survival, prepare to be dissapointed. This novel is 100% kingdom building, with a focus on summoning "heroes" from various works of fiction to build up a village with other players from earth and go to war with other villages. If the latter is more your thing, I totally understand, but personally I hate kingdom building as a story focus so I'm not the biggest fan.
For those of you who don't math, just in case you were wondering, three hundred out of every 3.5 million people would make the global population something like at least 11-12 billion. Could be as much as triple that if he accounted for age groups and such, though.
