The most broken thing about this novel isn’t Noah, it’s the fact that everyone on earth can become near infinitely powerful only being limited by how much they can farm and time. You could farm F rank dungeons and eventually fart out a legendary skill. 1L=4E=16S=64A=256B=1028C=4096D=16348E=65536F So, to be fair that’s ALOT of skills. But it is POSSIBLE for every single human on Earth as opposed to anywhere else. Focus is literally infinite power for Earthlings.
