In modern external armor casting, technologies such as sound waves and magnetic fields are used to interfere with the formation of crystals on a microscopic level, further enhancing the strength of the plates.
And powerful forces, of course, can destroy this crystalline structure. Sustained high temperatures or instantaneous kinetic energy will do the trick.
Over time, this microscopic order will gradually be destroyed, and the strength of the entire external armor plate will decrease.
But to be fair, even at this point, the strength of modern plates is greater than those of the Old Era.
This is an inevitable result of the basic development of physics.
And what Xiang Shan is cutting through now, is another situation altogether.
When carbon fibers burn, they release high temperatures of thousands of degrees.
