End of the Road: Despair Gives Rise to Hope, and Hope Hides New Ideas

In the future, mankind's excessive destruction of the earth will cause the greenhouse effect to completely go out of control, global sea levels will rise sharply, and extreme weather will wreak havoc on the earth. Desertification of cultivated land and depletion of fresh water resources have triggered a global food crisis. Countries have fought for resources, and then formed alliances to demarcate borders and build walls to seal off the remaining survival resources. The ecological chain completely collapsed, civilizations outside the alliance quickly perished, and the survivors became doomsday believers in the wasteland; within the alliance, they worked hard to develop technology. After breaking through in interstellar navigation technology, various forces built ships one after another and fled. In the end, only the last lonely city is left on earth - the City of Hope. Now, the City of Hope has also been destroyed, and the alliance with interstellar technology has all gone to the stars, but the unfinished experimental product Qi Shenqu and the failed product Ren Nao are left behind.
