This Guy Isn't an Armor Hero

[The pacing isn't especially fast, but it's not slow either. I tweaked the setting a little, since otherwise the Armor Heroes' power levels would be a bit vague.] [This doesn't follow the original story! It's a newly born world, so don't assume the original setting applies.] [The protagonist isn't a great villain. Even when it comes to Duanmu, Duanmu Zheng is righteous to the bone. How could he possibly be a ruthless scoundrel?] After pulling an all-nighter and dying suddenly, Shen Ming finds himself in a parallel world, only to discover that Armor Heroes are real here?! A chance encounter brings Shen Ming into contact with the Armor Heroes. Armed with mass-produced armor, he fights his way into the Shadow Realm one step at a time! Elements, psychic energy, the Five Elements: I want it all! Shen Ming: You know my first armor was Lava, right? So isn't it only reasonable for me to bend the rules a little? Defense bigwig: This guy's already calling himself emperor! What kind of hero is that? He's no Armor Hero! [The armor has some bugs the author can't fix, so consider this your warning.]
