power level and mana cores explained

Hello readers I am the Author i am writing this chapter to clear all the doubts that everybody has with power levels and cores and the things not explained here would be explained later in the novel.

Till now humans of the of the world in which James is only know that there are 9 class with class 1 being the weakest to class 9 being the strongest and each of it is divided into 3 levels .But there may be more levels or class that they may or may not know about so let's see ...

So It goes like 

Class 1 (Low-Rank)

Class 1 (Mid-Rank)

Class 1 (High-Rank)

Class 2 (Low-Rank)

Class 2 (Mid-Rank)

.

.

Class 9 (Low-Rank)

Class 9 (Mid-Rank)

Class 9 (High-Rank)

That was for the Classes and levels now to cores 

Cores are the unique object found in humans and beasts in with which they can store and use Mana easily , but cores are made only when once and that too in the starting of journey of a Ranker so people have to try to make their core as strong as possible with what ever materials,treasures they have because they only have ONE chance to do it . The weaker the core the weaker potential you have .

So here is the order 

White (weakest)

Red 

Orange 

Blue

Silver

Gold (Strongest)

Grey(????)

They are each also divided into three levels .

The does not only depend on the material and the physical body you have but also on the Quality of your soul so if a person has very poor physical body but a very precious soul he , who should have got a Red core would be able to upgrade to Blue or maybe even Silver , who knows . Soul can increase your quaLITY OF CORE BUT PHYSICAL BODY CAN'T FULFILL THE gap to increASE your core .
