'Humans naturally breathe in energy from the world and refine it into qi in their body, this qi goes through the lungs into the heart, but controlling this qi is a different matter entirely.'
'Qi is the life energy that exists within all life similar to blood, energy from the air is taken into the body and refined into qi.'
'It flows from the dantian that's similar to a heart through the meridians that's similar to blood vessels and back into the dantian in a cycle.'
'This is how qi circulation works and moving qi is done through meditation and controlling that qi with your knowledge of the human body, feeling that energy inside every part and then using your imagination to move it in anyway you want through the meridians.'
'Humans in this world naturally already have mana inside of them that exists in an organ that slowly replenishes this mana when its all used up.'
'This organ can be trained to house more mana but gathering that mana requires taking in external mana called magia.'
'Humans naturally absorb external mana from the air through the skin, but it isn't nearly as efficient as how humans in the murim naturally gather qi, Controlling this mana was even more complicated'
'Mana, more specifically in this instance 'magia' is the life and chaotic energy that exists everywhere in varying quantities and quality,'
'When it enters the body its still magia until the human manually refines it themselves by clashing it with the mana already naturally inside the human body.'
'Then after being refined, it turns into blood, so in order to refine this external magia one needs to know how to move their inner mana which requires a mana circulation technique.'
'Mana though is vastly more powerful and harder to control, '
'In order to refine mana, one must be able to sense mana in their body and external mana entering their body, which at first requires concentration until they reach a new level.'
'After sensing both, the body will then recognize the external magia inside the body and send mana naturally in the body from the core/mana heart after it, similar to white blood cells going after viruses.'
'Then the two energies will clash causing them to combine into mana and causing the mana that's already there to split into more mana. Then this mana will go back into the mana heart. This is how mana refinement works,'
'In order to move mana one must sense their mana but only their own mana, then they must have knowledge of the human body and where the pathways are,'
'then they will feel their mana after those previous steps, after feeling their mana they must move it with their imagination'
'Now the most important part about mana, mana circulation techniques aren't actual techniques but rather, it's a spell.'
'Mages aren't actually naturally able to use the mana pathways in their body without the spell which at lower levers they have to increase their mana reservoir in order to be able to use"
'Mages can still move mana naturally but only the mana outside of the pathways which is low quality and quantitative amounts of mana'
'Knowing how both work, I've deduced my objectives.'
'Because mana is absorbed through the skin, naturally it makes sense that more mana is able to be entered though wounds.'
'If I can wait just a little bit more and gather all of that raw mana, ill be able to have enough outside of my pathways for one weak basic spell.'
'Then I'll have to rip my shirt off and create a tourniquet quickly in order to stop the bleeding.'
'Lastly ill create my own pathways similar to qi pathways in my body by imagining the qi pathways and then sensing mana only in those pathways and no where else in my entire body.'
'and because i dont have a dantian ill have to use my real heart, not my mana heart because, my mana heart already has its own pathways.'
'If I create new ones I won't be able to use them as it'll gain an additional requirement for needing a mana circulation spell as the mana heart will recognize the new pathways as its own.'
'After making my own pathways and sending mana through my heart, ill have to keep all the mana their and make the heart slowly absorb it.'
'Then I have to send the mana absorbed from my real heart back into the pathways I created, this is to ensure I don't accidentally circulate in reverse which will immediately kill me.'
'This is how ill mimic qi circulation and how ill be able to use the tang clans rejuvenation technique with only mana and no spells required. Well at least in theory'
