The Digger Came From The Mythological Age (Isekai dato omottara hōkai shita miraidatta ~ shinwa no jidai kara kita hakkutsu-shi ~)
The volume 1 for this is free on Bookwalker right now, and I figure it's kind of a different enough setup + hero job specification (archeologist?) to highlight briefly.
What is this?
It's an Isekai story, but it takes place in the future after the world collapses (kind of like Doctor Stone). It sounds like part of the 'cheat' for our hero in this future society is basically the knowledge he has of his past world helping him to dig out treasures and artifacts.
Synopsis (Rough Machine Translation)
Japan aims to revive in a future where the civilization has collapsed. The popular web novel archeological excavation fantasy will be a book!
High school student Sora came to wake up not only in a different world but in the future after 4000 years! And it turns out that it is Japan that has seen a catastrophe and civilization has degenerated.

To develop a lost society, cheat of modern knowledge and new age aiming to be an "excavator" who digs out artifacts of the mythical age by making use of the ability "Qi".
