The virus has destroyed civilization, and the world has become a purgatory of the weak and the strong.
In this scorched earth occupied by radiation and mutated creatures, former SWAT team member Lu Jinghan relied on his excellent survival ability to survive alone, while medical student Gu Yanshu relied on knowledge and faith to survive among the ruins.
An encounter in a desperate situation brings two parallel lines together.
The calm and decisive warrior and the hopeful doctor went from being a temporary alliance with mutual reservations to walking side by side in life and death.
They searched for the legendary human stronghold "Beacon of Hope" in the wilderness, but found themselves caught in a cruel test about humanity, power and betrayal.
When the force called "New Order" implements the bloody "Purification Agreement", when the mysterious "Mother" and the "Pathogen King" who can reshape life surface, the abandoned refuge "Valley" discovered by Lu Jinghan and Gu Yanshu becomes the last fire for mankind. They must lead the survivors to fight a bloody path for the weak light of civilization in this desperate wasteland.
From relying on each other for life to protecting one party, the flames of war forged a bond that transcended life and death.
But the ultimate enemy is far beyond imagination - it originates from deep space, lurks in genes, and intends to rewrite the laws of the entire world.
When Gu Yanshu resolutely diverted away the shadow of destruction, Lu Jinghan stuck to their common oath.
Above the ruins, the night is still long.
As long as faith persists, can this glimmer of light ignited on the edge of ashes truly illuminate the dawn of mankind?
