In The Shadow of Death: The Villain's Survival

What the hell is this? I was reincarnated in the novel “Breaker of Destiny,” which I read as the protagonist. What is the protagonist? No, the third-rate villain, Ash von Agnus, the illegitimate son of the Emperor, the most hated person in the novel, is initially a minor antagonist in the novel, and he serves as a starting point for the hero and is destined to die in the most tragic ways, but regardless of this, this accursed world is headed for ruin. Oh, whatever, nothing connects me to my previous world, no family, no one, I was alone and I still am, nothing has changed. For better or worse I will live this life. I still remember all the details of the novel, and with my knowledge I will kill, survive, change my fate, and save this damned world.
