The world is extremely cold, civilization has collapsed, laws have become useless, and the strong are all beasts.
There are no zombies here, only the evil of human nature and the difficulty of survival.
There is no exaggeration of superpowers here, only fist-to-flesh fighting and interlocking tactics.
Since there is no king's law in this world, then we must formulate the code with our own hands. Only if we can protect our families and defeat the villains can we deserve to live!
