The Idle System, classic reincarnation story where the MC gets a pop-up system designed around idle games (like cookie clicker) where the entire point is to invest time to gain upgrades - either to upgrade abilities or to lower time investment cost of future upgrades.

I'm not gonna say it's great, but there are audiobooks for the first 2 (maybe 3 by now) books, and I've read all 4 that are out and am looking forward to whenever the 5th drops.

It goes into Cultivation by the end of the first book, as well, so I guess it's a Xianxia novel on top of being litRPG. Minor spoiler (not about the story, just some worldbuilding that they mention partway through the 1st book) but each person reincarnated from Earth gets their own unique system, so while the MC's is based around idle games past systems were designed around other types of games.

It's by Pegaz A and the book can be found here. This is the description provided by amazon.

" For John, death was merely the beginning. Transmigrating into a new world granted him an opportunity to change his view on life.


With power and immortality as new goals, he is willing to pay any price. Unfortunately, there are those willing to take advantage of him and his unfamiliarity with a new world. Shadows behind the curtains, unwilling to reveal themselves, will trick him into doing their bidding.


Now, John faces an entire kingdom on his own. Deceived? Conned? They don't care. His actions carry a sin none of them are willing to forgive.


With the world as an enemy, John will fight to accomplish his goals. His path will be stopped by no one.


Read this novel to enjoy a journey of self-discovery, ambition and revenge. Inspired by classical LitRPG, Xianxia and Fantasy, Idle System is a new take on these genres. If you've enjoyed novels like Ready Player One, Main Character Hides his Strength or Dodge Tank, then you're bound to love this book "

​

Obviously the obligatory nod to Ready Player One is an instant turn-off for me, a book I would consider one of my least favorites. Again, the description is quite vague and cookie-cutter.
