Reincarnated into a Doomed Novel as an Unknown Extra

What would you do if you reincarnated into a doomed novel?

Would you rely on a system to get stronger?

Steal the protagonist’s opportunities?

Kill your future enemies before they even rise?

I had none of those options. I only read the free chapters.

No cheats. No system. No future knowledge.

But that doesn’t mean I’ll wait for death.

If the world won’t give me a way to win—I’ll just carve one with my own hands.
