Obtain Xingtian Armor at the Beginning

The protagonist, Dawn, travels to a world full of monsters, where everyone can summon various armors. Let's see if he brings hope to the world as his name suggests. In 3120 AD, the world suddenly changed dramatically. The entire earth expanded countless times, and a number of monsters appeared. They have no sense and kill everyone on sight. Ordinary weapons cannot cause harm at all. Countries can only use missiles to kill monsters. Humanity suffered heavy losses. At this moment, someone awakened the armor, and human beings relied on this meager power to have a place on the earth. This novel and its characters are purely fictitious.
