Day 172 when acid rain corrodes the world. Lin Yan, who has an aura that is as cold as gunfire, and Shen Du, who has an aura as clear as falling cedar forest, meet in the crumbling ruins of the research institute.
The two have the same goal in mind and work together to find the truth and evidence left behind by the "Purifier" experiment.
One is good at long-distance raids, and the other is proficient in close combat and data deciphering. Two equally strong and aloof souls, from the initial conflicting tactics and divergent ideas, to being in desperate situations and walking side by side again and again, gradually developed a trust that is completely backed by them.
Together they fight against the dangerous creatures wreaking havoc and mutate, break through the layers of conspiracy traps set by the purification plan, and protect each other under the double threat of severe natural disasters and unknown crises.
From the life-and-death showdown in the underground database to the glimmers of light supporting each other in the ruins. Two equally strong and lonely people move forward side by side in the apocalypse of collapse and despair, tearing apart the shackles of darkness.
This is not only a desperate adventure of struggling for survival, but also a long journey of two similar souls bonding with each other, redeeming each other, and heading towards the dawn of the sky together in the barren years.
Intention: Even if the world is corroded by acid rain and humanity is on the verge of desolation, the strong do not have to go alone. The two contradictory yet compatible Alphas put aside their confrontation and trusted each other, sticking to their consciences in the cruel apocalypse and resisting the evil experiment that ignored life. It proves that the extremely strong can embrace each other for salvation, keep their true hearts amidst the ruins, and run for hope together.
