When the dark sun fell, nine months after the collapse of civilization, Levi huddled in the stench of corpses in an abandoned clinic and survived. When the tide of corpses smashed through the last barrier, a red-haired man as fierce as a chariot kicked out a way out, but the cost was that his bespectacled companion was bitten through the calf. Facing the veteran's cold "mercy" muzzle, Levi took out the last tube of blue potion that he had hidden for a long time and had a strange source.
A huge gamble with life begins. The dying young man undergoes drastic changes under the influence of the drug. He actually retains human consciousness, and a cold military code tattoo appears on his back. He transformed his body into a barrier, tearing open the blood path for Levi and others, leaving behind a thrilling mystery: Is the blue liquid salvation or a deeper curse? What dark plan does that tattoo point to?
Desperados, mysterious potions, military mutations... Levi was forced to set foot on the rusty wasteland, struggling in the endless tide of corpses and the abyss of humanity, just to uncover the shocking truth behind the doomsday. To survive or not to survive? The answer is hidden in every tube of blue fluorescence.
