In this vast universe, the only ones who are actually small but claim to be great are us humans on earth! Because of our own original difficulties, in the course of human development, we have missed excellent development opportunities again and again, without knowing how to reflect or cherish them. We think that we are God's favorites, with seemingly endless resources; we think that we are the natural masters of the universe. As a result, we went further and further down the wrong path, and finally one day in the future, mankind found a powerful enemy for itself, and they made up their mind - mankind must be eliminated!
When human civilization is about to come to an end, people on the earth are closely united. Sincerity, wisdom, unity, bravery... All kinds of excellent qualities formed by human beings in the process of evolution are vividly displayed at this moment...
However, the near-death struggle still cannot reverse the process of human destruction. At this time, humans realized that they had missed too many opportunities. Before the tragedy occurred, relying on unstable space-time technology, we focused our attention on the latest opportunity for human development - the rise of New China! Once upon a time, the developed Western world, out of complex mentality, cruelly stifled China's renaissance. Towards the end of human civilization, humans finally realized the mistakes they had made, and tried to go back to the past and change the future. What they have to do is: "Save China! Save the world!"
People in the future traveled through time and space and returned to the past! They are making new history!
