In the twenty-first century, the earth gradually began to enter a period of peace. However, a gravitational wave signal from the other side of the galaxy directly broke the hard-won peace. Legend has it that during the explosion of the universe, the huge energy generated by the explosion was directly transformed into strange crystal "crystal sources". Such crystals wandered across the universe, were absorbed by dust, and eventually evolved into planets. And the special energy emitted by these crystal sources creates the most magical existence in the entire universe - life. A force of advanced civilization has invaded the Milky Way. With the goal of plundering the crystal source, they are constantly encroaching on every planet with life, turning everything they go into dust. In order to cope with the war that they will face in the future, people have shown unprecedented unity. While they are frantically developing technology, they are investigating the truth about the crystal source. As a result, the earth has undergone earth-shaking changes, with more frequent natural disasters, severe species mutations, and even giant creatures that should only appear in science fiction movies, giants of light, have appeared one by one, gradually plunging people into deeper darkness...
