Bloods

I have something bugging me. And its why not everything can use magic. Especially the invading humans, they have sufficiently advanced technology for molecular deconstruction. However they aren't capable of using magic. 
I have blue blood, and its probably the easiest thing to manipulate with my magic.
I have a hypothesis its: "all creatures that have magic similar blood type to me."
My reasoning: humans, most mountain eaters and several animals cant use magic. Additionally, the Kuroik and dragons are capable of magical feats.
In order to test my hypothesis, I plan on collecting blood samples from other creatures that can and cant use magic. Otherwise I could try communicating with doctors and biology experts of civilizations. Inorder to compare and contrast the differences between us.
When i was young, I was a doctor for my clan, and i learned that us Mountan-Eaters have different blood types. The substance we have as blood is primarily the metal of our diet as children.
I was one of the few children that grew up on a heavy diet of copper, which is highly unsual. 
I'm not familiar, with the dragons diverse anatomy, so I will find a medical expert in the Xkhanku's Abyssal spire and explain the biology of the many dragons. 
I hypothesize that their proximity to copper influences there ability to use magic. And copper is the reason why i developed magic.

I've talked to one of the doctors in the Kuroik kingdom, Tsumika. And I've learned something quite interesting.
They are basically an organism made of multiple microscopic robotic organisms. They call these micro machines "Keiraits". 
Their bodies harnes the energy released from reverse-matter mater explosions in order to keep themselves energized. 
Interestingly, copper is there primary nutrition source. And it is used to create the super heavy element Kurozmium. 
Tsumika reviled to me that their bodies contain an unusial state of mater. They call it inverse mater. 
Inverse particles are essentially the mirror image of its corresponding matter particle, with opposite charge but identical mass & spin. For example, the antimatter counterpart of an electron (which has a negative charge) is called a positron, which has a positive charge. When a matter particle comes into contact with its corresponding antimatter particle, they annihilate each other, releasing energy mostly gama rays. however when inverse kurozmium and copper touch they release keimei particles and allow for energizing of there keireits.
The excess inverse waste product gets used by Nanites to rebuild Inverse Kurozmium for future reactions.
Their bodies have a special organ, Rikai that produces a metalic looking inert fluid they call Shikei.
They process inverse mater mater collisions in the Shikei. Shikei circulates throughout there body like blood.  Shikei contains, both mater and inverse mater, aswell as the the Nanites and Keiraits that process it. the reaction releases Keimei particles and the Nanites give them enough energy to do whatever they need to do.
whenever they produce excess Kurozmum there bodies are able to catalyze magic better.
I'm wondering if this is similar to my body. as ive gotten better at magic I've grown quite a bit heavier and have more Kurozmum in my body and in my blood.
 that they aquire the nanites from there parents when they are concived. and all requred to grow into there fully developed form
after they are born typically they inject their children with a nanite growth solution or remove some of their own personal supply, so the child can have an increased ability to produce nanites or nanite supply so they dont have to wait 20+ years before they reach there peak saturation. and full maturity.
 they can live without the injection, however, they are only able to use small quantities of magic and are required to eat weekly instead of yearly, additionally they produce more waist product and arnt able to consume as much in a single sitting.
doctors occasionally administer nano-containment liquid as an energy booster for the children who train themselves in more traditional magic or chronomancy.
given most kuroik practice kronomancy they dont typically travel more than 15 seconds as children and 15 minutes as adults. this is usuially a limitation of there energy supply rate and how much kurozmium is built up in there body.
