Tianyuan Defense Line

A letter. From a dead civilization. Before it disappeared into ashes, it used up all its energy to shout one sentence to the universe: It is coming. We didn't survive. You still have five years. Five people. A paralyzed Chinese pilot, wearing armor forged from ancient stardust that crashed into the earth 4.5 Billion years ago. A British genius who became the richest man in the world at the age of nineteen has the name of the deceased engraved on the inside of each piece of his uniform. A South African miner parasitized by an alien nanoswarm contains the last words of an entire civilization. A Singaporean assassin who resonates with dark matter can hear the universe singing every time he strikes. A thousand-year-old exile with an artificial star burning in his body, to protect him is to die. A lie. Governments secretly built arks behind them—not arks to fight, but arks to escape from. A door. Inside the door are the breaths of seven billion people. Outside the door lies the eternal abyss. The light leaking in through the crack in the door is fire. The fire is not out yet.
