"The technology of 'Composite Armor' and 'Barricade Armor' is not that difficult, at least not as difficult as 'Magic Salt.'
Simply put, composite armor is the opposite of homogeneous armor.
Homogeneous armor is made from a single material, such as steel armor, aluminum alloy armor, etc., with respectable defensive power. However, to substantially increase the defense, the only solution is to continuously increase the thickness of the armor.
Composite armor, on the other hand, is made from two or more layers of protective materials with different properties. Due to the differing properties of the protective materials, their physical performance also varies. During the process of an external attack attempting penetration, the different physical properties significantly alter the course of the attack.
