Human science and technology has been developing for many years. Our ancestors brought all the advanced technology on earth and wanted to explore the outside of the universe. When they reached the edge of the universe, they used special technology to open the door to a new world.
But when the door opened, they saw something that shocked their world view.
They were extremely powerful monsters individually. The ancestors knew very well that if these monsters were allowed to enter through the gate, it would be a disaster for the entire original universe, so they finally closed the gate when almost everyone died. The remaining people knew that they did not have much life left, so they sent a storage ring back to the earth, hoping that future generations could open up a new technological world. Five hundred years later, Shangguan Yunxiao and his wife Lu Shiyun led human civilization step by step to the peak, and finally the monsters outside the universe launched a final decisive battle.
