Review Detail of kaadusc in Idle Mage: Humanity's Strongest Backer

The background of the story is well and good. The character’s are also alright. It’s just that the cultivation system of this world is a bit complex and I didn’t really understand all the power levels and what exactly does one have to do to become stronger. And also what exactly is the use of providence. Like is it luck? Cause the MC is really very unlucky compared to many others I guess. So if you could actually describe all the terms it would have been great. I mean the MC had access to higher level knowledge after going to academy so you could have put a chapter which described all these terms.
