Do any of you knows Kingdom Building novels where MC is OP like Overlord Slime Tensei Breath of Creation It's fine if its RRL or FF.net
I second "The World Online". That one is amazing. "I am the Monarch" is also good, but really slow release cycles. "The Amber Sword" is fantastic. I am binging "The Lord's Empire" on lnmtl right now and have to admit that it is both good and bad at the same time. Author resorts to dbz style fights every 30-40 chapters to try to drum up tickets. If not for that, the story would be at the top of my suggestion list.
Here 5 pages for kingdom building most have an op mc at the helm many will be your bland usuals but good ones in there as well https://www.novelupdates.com/stag/kingdom-building/
Yes, in the beginning and he doesn't have any OP powers, but it is one of the best kingdom building novels
