Betrayed in the Apocalypse

Summary

Eight years ago, I was transported into this post-apocalyptic power fantasy novel as the same-named expendable nobody.

I had the ability to create a large-scale radiation shield that could block zombies. I was the only S-Rank ability user in the entire colony.

But because my younger brother, Samuel Grant, failed to awaken his ability, my only purpose became providing him with "upgrade materials."

I tried to fight against the story and refused to hand over my crystal core.
