Now that all that is out of the way on to the rankings
Plot: 9.4/10 Honestly after Cheon Yeon-Woo becomes the leader of the Demonic Cult it kinda fell off but then resurfaced itself which is a huge accomplishment when comparing too most Murim Manhwa’s
Main Characters: 10/10 ARM FOR THE ARM GOD
Art: 10/10 Demon Slayer Level
Character Development: 8/10 Besides Cheon Yeon-Woo there is much
Side Characters: 7/10 Other than Hu Bong and Moon Gyu the side characters are very one dimensional and uninteresting. Especially if you consider the elders who were just annoying to read about and turned me off many times. The Gate Guardians are very good though.

Overall 8.8
I know most people consider this one of the best among Murim Manhwa’s and I agree with you. But that’s not a very high bar that people are asserting because most Murim Manhwa are boring and generic. But Nano Machine is different only because of Cheon Yeon-Woo, god he is such an amazing MC and leader among all of his people and every time he was on a panel I would become completely invested in the story. The Art is also spectacular especially during fight scenes. The side characters are very boring and generic other than the greatest character in all of fiction Hu Bong, and Moon Gyu. The character development is above average but nowhere near good enough to give it a higher ranking than what I already gave it. Overall, a good read especially if you like an MC that collects arms MWAHAHAHA ARM FOR THE ARM GOD.
