I think he uses the mc's naivety to scam him. Like selling the tungsten rod for more money than its worth and the hi potion being empty. 20 bolts for 100k was probably a fib as well. He's helping him but also taking him for a ride.
It's annoying how this guy just resigned himself and accepted his death with a self-satisfied smile on his face. He doomed the country at the cost of his own life. I wanted him to suffer and stew in his failure and foolishness until he burned.
I hope the translation team doesn't do what I'm thinking. Changing Korean names to western ones is so strange. Seeing a "Josh Kim" or a "Brandon Park" appear is always comical and silly.
I read this years ago and it's only now that I have gone from the start to the latest chapter. 50 chapters and it feels like the story was sped through as fast as possible. It's interesting, but it's soley comprised of "and then" storytelling.
