So onto this part of training, I don't need you to explain to me what PoR is, rather just read up on it. Once you've read up on it, I want you to try and up your own Resistance by focusing on your chakra at its core. This, when you look at the chakra circulatory system, is the central spiral network of chakra paths thats surrounds your chakra source, normally located in your abdomen. When you focus on it, you need to visualize a growing yellow and warm aura, spreading from your core, outwards towards your skin. Its this focus and this will that will make your chakra passively aggressive towards pathogens and most natural toxins and infectious diseases. This chakra is invisible to the naked eye and doesn't go beyond the users skin. However, doujutsu might see the aura growing and expanding from the medical ninjas core.
Give it a shot.
