i agree with that theory the only way is to defeat power is with more power. the ancient kingdom probably had their own weapon used against them. but shouldnt they have a way beat their own weapon. i dont think they kept the blueprints though because then what did franky have. he said that it was the blueprints that were passed from shipwright to shipwright. so they couldnt possibly have the blueprints. now if they didnt have the blue prints then the weapon couldnt be built. so my guess the ancient kingdom's weapon was captured in use and was used against them.
