Actually some have said that the NLB is the ice breaker back in 1881. Dr Shin proposed if he could some how figure out how to manipulate spin metal, relic iron, spirit bloom, and helium filaments all into one, it would actually regenerate ammo. Few years later, Dr Shin figure it out and put the auto regeneration core into the no land beyond, but a new metal frame around it and took off the bolt action as it was not needed anymore. So moral of the story is...is sucked before.
