Have you ever seen a hundred-meter-tall giant strolling leisurely through a modern human city? Have you ever imagined a world-ending divine bird dwelling above the firmament, constantly looking down upon the earth? Have you ever heard of a civilization that calls itself God, arriving from the far side of the stars? Starting in his first year of high school, Chen Du has had the same dream every single day. In the dream, there is a blue crystal. After 30 seconds, the first wave of monsters appears. These monsters have a single, unified goal: to destroy the crystal.
