@DAD there's a reason for that in the manhwa it never goes into details about how he gets strong the manhwa glances over it and says the blade cult in the future pretty much wants domination so they're sending someone back in time to off the strongest person in the cult being cheon so he was actually really strong, he probably gains strength after the training ( i don't know never read the novel if there is one) but regardless he was the strongest in the future records for the opposing cult the blade cult wants their position
