Within a few days, Konoha redeployed a large number of personnel to the front line in Demon Country.
A new line of defense was established.
The first thing they needed to defend against was Magnet Release.
Magnet Release was not yet powerful enough to remotely separate the iron contained in a human body. It still remained in the category of contact-based killing.
In other words, without contact, there was no threat.
So how could they guard against Magnet Release?
A nonferrous-metal isolation layer.
Here's a basic fact: metals are divided into magnetic and nonmagnetic metals.
Nonmagnetic metals were unaffected by Magnet Release.
The former, magnetic metals, were ferrous metals, including carbon steel, cast iron, wrought iron, and stainless steel.
They were the most common metals in the Shinobi World, produced in large quantities and used in construction, furniture, components, cookware, home appliances, drugs, medical equipment, and many other fields.
If this were a highly industrialized society, the lethality of Magnet Release would be terrifying.
To be fair, Konoha was a biotechnology-based society with relatively little dependence on industry. Thanks to its abundant forestry and animal husbandry, many basic materials were biological, and some were even living organisms. It did not have to deal with the most troublesome problem: EMP, or Electromagnetic Pulse attacks.
Otherwise, after a single Electromagnetic Pulse, the paralysis of all equipment, especially the electric grid, would bring about a despairing scene in which everyone could only wait to die.
So how could they defend against Electromagnetic Pulse attacks?
The simplest method was a lead-plated isolation layer.
In other words, a sealed layer made of nonferrous metal.
Metals that did not contain iron were called nonferrous metals. These materials had different properties and mainly consisted of pure metals and iron-free alloys. Besides aluminum, lead, and copper, precious metals
