The story takes place in an imaginary future world where the earth is facing a serious energy crisis, environmental degradation and the imminent threat from outer space. Human society is in a state of "technological bottleneck". Most advanced technologies are in the hands of a few superpowers and multinational companies. Ordinary countries and people around the world are overwhelmed by various restrictions and blockades. At the same time, some "black technologies" are quietly emerging. Especially through some special technical systems or platforms, ordinary people can break through the conventional technological level and discover black technologies beyond imagination.
