Just know that these ranks ONLY apply to this world

The way to rank up is similar to how we rank up in games. in order to get a rank you need to unlock 4 meridians to rank up to mid u need to unlock 8 then 12 note that this is only to get low f rank. after that to get e rank you must "rebirth" and all your meridians would close but you would keep the power. you will unlock abilities from a bloodline when you get to mid in every rank but this is a low chance except for the mc since he is the progenitor of the world. You can also create abilities but this will take extensive amount of time, concetration, and power to do this.
