Later he joins a rival group to spy on them and get information on other groups.
He travels to other plantets useing portals and flyes alot and kills stuff from the air.

Frank, that's a good start, but we need more information in the header at the top of the page. Many members only read the headers. We have thousands of book requests, so threads with vague headers are closed.

Copy the genre (e.g., adult or teen fantasy, thriller?) and plot details (e.g. it's unclear what "cultivation" means) from your message #1 to the header by clicking the small "edit" link after the header. This only works on the full Desktop website - not the Mobile website or app. (On the Mobile website, there's a "Desktop version" link at the bottom of the page.)

- Around what year did you read this book? A range of years is fine.

This is the series The Idle System.
Looks like you probably read book 4
