Ling Shuang was once a low-level garbage worker at the Seventh Recycling Station and was persecuted by Gu Fei as an experimental subject. In order to survive, he exchanged the "Primary Source Loan" for the "Aberration Viper Body" and used the lives of ten guards to repay the initial debt, but he also paid the price of having only 29 days left in his life. After Ling Shuang escaped from the recycling station, he was marked by Gu Fei with "Ghost Spores" and became the target of the aberrations and pursuers in Area D. In a desperate situation, he reached a deal with the mysterious weapons expert Ah Jiu to hunt down giant rats to obtain source cores to extend his lifespan. After her hearing recovered, Ling Shuang swiftly fought back against her pursuers, learned of Gu Fei's plot, and finally declared war on Gu Fei through the communicator. A hunting game about survival and revenge officially kicked off.
