Transmigrated to the world of Demon Slayer, only to become a swordsmith?
    “Then I'll forge the strongest Nichirin Blade!”
    With each hammer strike against the iron ingot, a notification appeared...
    [Impurities -1]
    After a hundred refinements, another notification...
    [Constitution +1]
    Upon completing the weapon, a final notification...
