Survivor: the Spark of Civilization

When all mankind is reveling in heading towards the universe, only I know that it is a ticket to the abyss. I, the only survivor from a super civilization wiped out by "sweepers", disguised as an ordinary student. My brain is the last tombstone of the mother planet and the only way for mankind to survive. In order to take revenge, and to prevent this blue planet from repeating the same mistakes, I will personally reverse the technological tree of mankind and lead them... To ascend!
