Post apocalyptic sci-fi story where the MC is a scavenger looking for remnants of the fallen high-tech society. MC is aided by an augmented reality AI that makes a certain contract with him in the beginning. Unknown to the MC is that he is the 499th person the AI approached with the contract, apparently things did not go too well for the other 498.
Lots of action scenes and detailed descriptions of weapons and gear. Overall a great series if you like sci-fi action.
That's strange, I could have sworn there was a topic for this book that I'd previously upvoted that had a whole bunch more information about the series. Guess it must have gotten lost in the forum upgrade.
Anyway, looks like the series is up to 7 LNs now.
It's also apparently fairly popular making the top 10 ranking for LNs in the annual Kono Light Novel ga Sugoi! for 2020 and 2021 issues (Rank 5 for 2020 and Rank 4 for 2021) according to wikipedia.
A fair number of LNs that make this ranking appear to have anime series attached to them, so there's a reasonable chance that we could see an anime series come out sometime down the line
