In 2025, a mysterious signal originating from deep space code-named "Ghost" was intercepted. It is not a greeting, but a demonstration - a god-like display of technology that can manipulate the laws of physics at will, ultimately leaving an unpredictable equilateral triangle pattern.
This discovery made mankind convinced for the first time that there is intelligence in the universe that far exceeds its own understanding. The world is plunged into a mysterious upheaval. Countries are engaged in a dangerous technological competition around signals, triggering a technological explosion and tearing apart international trust. China launched the "Cornerstone" project to secretly build the "Ark", a fire that preserves civilization, and the "Star Torch", a space city.
However, mankind's reckless imitation experiments triggered a catastrophic "dimensional shock", which not only tore apart the near-Earth space, but also caused a retaliatory strike called the "Skyfall Incident" - an unknown force accurately destroyed major cities around the world by distorting time and space.
The surviving human civilization was forced to enter the "quenching" era. United for survival, they spent all their resources to build a huge "Star Torch" defense network in low-Earth orbit, and struggled to transform from a planetary civilization to a space civilization.
When humans finally plucked up the courage to send a message of peace, the reply they received was a coordinate and a question about the origin of life. Humanity stands at a fork in the road of survival: Should we retreat behind the "Star Torch", or rush to distant coordinates to accept the ultimate test for the qualifications of civilization?
This is the beginning of an epic story about civilization being forced to mature under fear and pressure, and struggling to survive through quenching.
