Peerless Underworld Armor

In the post-apocalyptic period, high walls that can reach thousands of meters thick and high-strength energy shields have created a civilized world that seems more prosperous than in peacetime, with both science and cultivation. Many people even forget about the dangers of this world and start to enjoy this kind of life. However, a greater crisis of world destruction is already quietly brewing. A top special soldier before the end of the world, a broken armor that survived a destroyed civilization, came to this world under such circumstances because of the design of a special being. I just don't know what is waiting for him, a chess piece in the eyes of gods and demons, or the biggest variable that can save this crisis. This novel and its characters are purely fictitious.
