Dig Deep

In the post-disaster world, humans continue to fight against mutant beasts. However, humans' biggest enemy is not the powerful mutant beasts, but humans themselves. The armor invented by human beings constantly improves their own power, and as the power becomes stronger, the desire seems to have no end... Evolved human beings stand at the top of the world and watch how a young man can purify the corroded barren land into fertile land that can be cultivated.
