I Am a Blacksmith, so It Makes Sense for Me to Be Stronger, Right?

[Another World] + [Slowly Invincible] + [No Heroine] + [Era Change] + [Immortality] Accidentally traveling to another world, Golden Finger is a system where you can become stronger only by forging iron! What can be done? Let's strike iron! When the extraordinary appeared in the world, Bourne was forging iron. "No, that's impossible, he's the devil!" The top supernatural collapsed and went crazy, and the forbidden magic that could destroy the city failed to work on this man. When gods were born and spread their faith to enslave all sentient beings, Bourne was still forging iron. "This... Divine magic has no effect!?" Bourne is impatient. He just wants to work quietly. Why are there always blind things looking for trouble? "Tell me, how many times do you want to kill me?" Extraordinary bloodshed, the fall of gods. I, Burn Ignis, just want to strike!
