Mechanical Age 1 Nanling City

April 13, 2035, 00:00. The dark night sky seemed to be torn open with a huge crack, and a dazzling arc of blue light appeared in the sky. It was the trajectory left by countless crystal blue fireballs cutting through the sky. They fell from the sky, as if playing the most magnificent symphony in the world. The air defense weapons of all countries were activated at the same time. Countless light chains and fireballs rose into the sky to meet the blue meteorites. Countless fireballs bloomed in the dark sky. However, these top human technologies did not change the result. On the contrary, the fragmented meteorites only expanded the disaster area. Debris fell like raindrops, and blue flames ignited all over the world. With the meteorite as the center, crystals spread on the surface. In just a few days, more than half of the human race in the world lost their lives, and 80% of the organic life forms were turned into metal in this catastrophe. The people who survived had to move to the relatively less affected and vast continental plates, where they built new cities one after another to fight against new enemies together. From then on, a new era was born, that is—— Mechanical Era.
