One day, darkness enshrouded the world. According to the Meltdown theory, Earth’s magnetic field faced a change, and along with it, natural laws changed too. Though some laws related to physics could still be applied, a lot of scientific theories and laws had been overturned, prompting everyone to re-discover their underlying principles. Humanity’s scientific foundation was not the only one which faced changes; the field of genetics had transformed too. One of the biggest disasters brought by the magnetic field’s change was the zombification of more than 80% of the world’s population. After years of struggling, a few lucky survivors would evolve and awaken a hibernating power hidden in them. Chu Han was never that lucky… While holding on against the first wave, humans weren't the only ones getting stronger. Soon, phase-1 zombies evolved into phase-2 then phase-3 and so on. Ten years after the mysterious meltdown, the world dominated by humans changed hands. Zombies were the new overlords, and humanity was facing extinction. One day, Chu Han`s consciousness returned ten years before the end of the worlds. A loud noise awakened him in Minqiu University’s dormitory. With only one day to prepare before the Apocalypse’s outburst, he slowly realized that he had been reincarnated! Chu Han’s sudden reincarnation brought an unexpected power, which he hadn’t in his previous hellish world. To be more precise it wasn’t a power, but a system! The Meltdown System! Despite losing his monstrous strength gained through years of harsh training, Chu Han was confronted as the Meltdown System could grant him talents in exchange for credits, which he could get with every zombie he killed. This is a story about a world on the edge of ruins, the Meltdown System, and Chu Han, trying his best to save the people he could not save before.
The bodies of dead zombies near Chu Han`s feet were now getting more and more. They were piling up very quickly. From the very start, Chu Han did not even move from his original post. He didn’t even look towards each of the zombies. It just seemed that he didn`t even need to look properly to kill them all.
The sounds of fighting from the other parts of the maze were getting lesser and lesser as the battle was coming to an end. The people standing on the roof of the lorries took the time to purposely check on Chu Han`s place so that they would be able to support him whenever it was needed since Chu Han`s place had the highest concentration of zombies. However, what they saw when they turned their heads towards Chu Han`s direction left them reeling in shock. Some of them who were not that good at shooting even missed their shots after lapsing in concentration.
