You can literally see that only mc doesn't have any plot armor... Other than him, everyone has it...well, most of the prominent side character has it
As far as I understand, this isn’t true. In Yang Bohai’s route, he mentioned that the MC’s case is special that only a madman would kill the MC. We don’t know why, but there must be a reason for this. Plus, the fact that the MC could spend more than two years in a coma with a human body and still survive is already plot armor to me, the fact that no one experimented on him, even after seeing that something special happened following the expedition, always seemed a bit unbelievable to me.
If the MC didn’t have plot armor, any Xiantian or Shangtian would have killed him a long time ago since he’s a total threat. Sure, the MC can die fighting other Houtians, but all his fights are at a level he can win, and if he can’t win, something always happens to save him. If that’s not plot armor, then I don’t know what is.
