Xiang Shan had a stock of EMP weapons on him, all collected from the wilderness. After the healing of his spine, he had learned to use these as a standard tactic.
Although "Iron Dust" could maintain a blockade for a long time and counteract electromagnetic wave weapons like lasers, it still needed time to spread.
Before "Iron Dust" completely covered an area, the enemy still had a chance to send out a signal.
But EMP was different; it propagated at the speed of light and could instantaneously cover the surrounding electronic signals.
If lucky, it could also paralyze a few people with poorly functioning electromagnetic defenses.
Of course, there were also drawbacks. The noise from the electromagnetic pulse was just too loud. Although invisible to the human eye, that was only for "human eyes." Not to mention prosthetic eyes, in an era where everyone had electronic devices, the electromagnetic pulse was too easy to detect, whether near or far.
