In 2077, with his last breath in the extremely cold ruins, Lin Yan froze to death with endless regret for being betrayed by his best friend and the tragic death of his sister. When he opened his eyes again, he returned to the university dormitory in 2067 - 72 hours before the outbreak of the Red Mist virus.
The countdown to the scarlet mist that would swallow the world was ticking in his ears. This time, he seized the opportunity to be reborn. Crazy hoarding of supplies, forcing his sister Lin Wan out of danger, and used a crowbar to smash open the first mutated head when the zombie wave first appeared. The blood in the corridors, the mess on the supermarket shelves, and the cold guns traded on the black market all became footnotes for him to rewrite his destiny.
Awakening the "Instant Flash" power, he met Su Qing, his comrade in his previous life, and together they carved a way out of the ruins. But when Chen Mo, his best friend who stabbed him in the past, appeared with a strange smile, Lin Yan was shocked to realize that he was not the only one who was reborn. The other party not only planned in advance, but also coveted the vaccine formula hidden in his mind.
From the besieged residential building to the crisis-ridden library, from the death tunnel surrounded by corpses to the strict-level purification zone, Lin Yan protected his sister and led his allies, step by step amid the torn between human nature and bestiality. He wants to regain the stolen hope, tear apart the masks of hypocrites, and even more, in this bloody dawn, open a way for those he cares about to survive.
The shadow swimming in the well, the experiments hidden in the purification area, and the deeper secrets behind the virus are waiting for them to uncover...
