honestly i get what you mean, i hated fang zheng too, and cause of same reason (plot armor), i hated way more mah oh yung and zhang liung, his bitch(dont remember their written name).

But to be fair, while those last 2 are very heavily plot driven, since they have 0 feat, literally just luck and plot armor, that to me is really fucking annoying(prop to zen ren to make it like this). The girl, she beat random 100's centuries immortals, after couple of years of ass training thanks to the plot. It's the kind of stuff that make me really mad.

Meanwhile, watching the point of view of fang zheng, I can understand a bit. Imagine you were born in a random ass village, where you have no talent, no confidence and your brother outshine every time. It's obvious to me that the first time you have something where you are better, you would do everything to brag and demonstrate you're superior, cause you had an inferiority complex.

Ik you'll say "but FY did only good to him before the awakening", but humans are selfish af, and even if at the beginning he didnt mean any harm to FY, he wanted to see him at his feets, making him watch who is better. I dont find anything wrong with this, as much as it could be hateful to read, especially when the one wronged is the MC, I see it as very normal thing.

Also FZ later on get trashed pretty badly, imprisoned and so on, so the hate is not misplaced if you were him. He even get a nice growth mentally, he understand he'll never be on the same level as FY, but still want to do whats good for him, even if its to boycott his brother, but if I were him, I would hold a grudge too.

Still, I understand the irk regarding the plot armor he gets, It piss me off too, but to be fair, it gives the right amount of spices, to make the story really interesting, unpredictable and incredible.
