External release of attack, the second way of attacking using the Gold Element ability, was a process of gathering energy to release it externally. In fact, every superpower could perform this, but the Gold Element ability had a superior cutting property, hence it stood out more.
Besides, it had other capabilities.
Li Ming touched the gunblades in his hands, able to feel the Gold Element power contained within them. He could manipulate this energy to alter its form, thus controlling the metal form of the gunblades themselves.
He could also control the energy to move in the air, allowing for control over the flight of the metal.
In addition to that, he could even extract these energies, turning the tough and rigid iron into waste, then inject it into another weapon to increase its toughness, until it reached the weapon's energy capacity limit.
Besides, he could slowly absorb these rigid iron abilities to enhance his own Gold Element ability.
