The composition of Celestial armor had always been a mystery. Su Ming had a chunk of heel cut from a Celestial Variant, but after all these years, even scientists of Howard and Tesla's caliber had failed to learn anything from it.
All they knew was that it was extraordinarily sturdy, with a melting point far exceeding the Sun's temperature.
At present, aside from Su Ming's Tenth Metal greatsword, no other known metal in the universe could even leave a scratch on it.
