I don't know if it's anywhere besides Amazon. https://www.amazon.com/WIEDERGEBURT-Legend-Reincarnated-Warrior-1-ebook/dp/B08188MS31/
I only recommend it if you love harems and s*x scenes. I feel the end of book 4 through the beginning of book 5 has about as much plot as a porno, and the author describes every thrust in explicit detail so you don't need to leave it to your imagination to fill in. Not sure what happens after the middle of book 5 though as I haven't gotten there yet.
Wiederburt by Brandon Varnell is very similar to Tales of Gods and Demons.
