I'm Just a Blacksmith. Isn't It Only Natural That I'm Strong?

[Another World]+ [Gradually Becoming Invincible]+ [No Female Lead]+ [Changing Eras]+ [Longevity] After accidentally transmigrating to another world, his golden finger turned out to be a System that made him stronger only by smithing! What else could he do? Get to the forge! When the supernatural appeared in the world, Byrne was smithing. “No, it can’t be! He’s a devil!” A supreme supernatural being broke down in madness. A forbidden spell powerful enough to destroy a city had no effect on this man. When gods were born and spread their faith to enslave all living things, Byrne was still smithing. “What... Divine magic doesn’t work!?” Byrne was getting impatient. He just wanted to smith in peace, so why did troublemakers keep picking fights with him? “Tell me, how many hammer strikes do you want before you die?” Supernatural beings bled, and gods fell. I, Byrne Ignis, just want to smith!
