Sephiroth Era

In 5700 AD, mankind was locked in a Type II civilization. The only key to breaking through the barrier - "Origin", sleeps in the Creation Crack 220,000 light-years away. Six civilizations have tried to touch it, and none have survived. Gu Han, a qualified navigation officer, piloted the living spaceship "Guixu" alone on an expedition into the abyss, but found that the source of matter was not an energy source, but a mirror. It only asks one question, and those who cannot answer it will be erased from the universe.
