In 2749 AD, the "Great Fault" disaster broke out. The interstellar colonial network of the old human civilization collapsed instantly, the super-light speed channels fractured into countless isolated star fields, and the space-time rift swallowed up more than 90% of the population and technology. The ground has become a post-apocalyptic wasteland filled with radiation, and survivors are lingering in underground bunkers; a few interstellar exiles are trapped on the edge of the "fault zone", struggling to survive on broken spaceships.
Ten years later, Lin Yan, the leader of the survivors on the ground, discovered the "star track key" that could locate the core of the fault in the ruins of an old civilization, but unexpectedly awakened the sleeping interstellar exile Su Lan. Su Lan's spaceship carries the last complete gene pool of civilization, and her bloodline contains the secret of crossing the fault line.
In order to find the legendary "oasis star field" that has not been affected by the fault, the two team up to cross the fault zone that is full of dangers - on one side are the mutated creatures and predators in the wasteland on the ground, on the other side are the turbulent time and space in the interstellar space, the mysterious "fault defenders", and hidden behind the fault, there is a shocking conspiracy about the destruction of the old civilization.
They must not only struggle to survive in the apocalypse, but also cross the chasm of civilization faults, and compose an interstellar epic about redemption, trust and the continuation of civilization between star debris and embers.
