Day 172 of the world being ravaged by acid rain. Lin Yan, with his fierce, gunpowder-laced presence, meets Shen Du, whose cool temperament resembles a snow-dusted pine forest, amid the wreckage of a collapsed research institute.
Sharing the same goal, they join forces to uncover the truth and evidence of the crimes left behind by the "Purifier" experiment years ago.
One excels at long-range planning and surprise attacks; the other specializes in close-quarters combat and data decryption. Both are powerful, proud souls. From clashing tactics and conflicting ideals to repeatedly facing desperate situations side by side, they slowly develop an absolute trust in one another, willing to entrust each other with their backs.
Together, they fight the dangerous creatures ravaging the world with their mutations and uncover the layers of conspiracies and traps laid by the purification plan. Amid the twin threats of brutal natural disasters and unknown dangers, they protect each other.
From a life-or-death showdown in an underground database to the glimmer of hope they offer each other among ruined walls, two equally formidable loners press forward together in a broken, despairing world, tearing through layer upon layer of darkness and restraint.
This is more than a desperate struggle to survive. It is a long journey through desolate years, as two kindred souls become bound to each other, find redemption in one another, and head together toward the light of dawn.
Theme: Even when acid rain corrodes the world and humanity teeters on the brink of desolation, the strong need not walk alone. Two Alpha characters who clash yet complement each other let go of their hostility and put their trust in one another. They uphold their conscience in a cruel apocalypse and resist evil experiments that treat lives with contempt. They prove that even the strongest can embrace and redeem each other, holding fast to their true selves amid the ruins and journeying toward hope side by side.
