With the Human Federation at My Back, I Fought Head-On to the End

The earth's crisis is imminent, and the technology of the Human Federation has come to an end. As a child of the earth's will, Erth embarked on a journey through dimensions with the Federation's top technology. In the face of magic, Erth: Nano Armor seems to be a little too easy to use. Facing the giant boss, Erth: The fire coverage is really delicious. Facing an opponent that he could not defeat with all his strength, Erth: You are right, but I am going to summon the federal fleet to come out and clear the ground!
