What the Hell Is This

In 2050 AD, the world changed. Thousands of alien races are watching covetously from outside the territory. On the earth, people suddenly fell into the primitive era. What is even more frightening is that countless plants and animals are evolving, but the human race is standing still. Just when people feel despair, the mysterious and rich voice of the will of the earth sounds: To my people, the alien race is coming, and I can only stop them for thirty years. I will give you the ability to summon creatures from the illusory world. Let all creatures fight! Grow in the killing! Be it animals or plants. I need your strength!
