The protagonist's power will be explain later, but if you insist on saying that you hate plot armor, then I can only say if I don't write it this way, many times there will be no this novel at all, because what is called plot armor is actually similar to the protagonist being lucky, lucky to a special extent! But if plot armor is completely removed, then theoretically, as soon as the protagonist encounters a dangerous plot, they could directly died, or seriously injured to death(Because only in this way can we call it absolutely consistent with reality). But this is a novel, if protagonist is dead, so what would be written afterwards? Unless the protagonist is never allowed to encounter danger, in this way, the protagonist won't get hurt or have adventures and you can completely get rid of what you called plot armor, but this makes it seem very bland, no drama at all. Actually, many times the fact that a person can survive in this world is in itself a matter of much luck. This world is not as you think where everything has inevitability, at least it is not perceptible at the level of ordinary people.
