Cultivation of Immortality in the End of the World: Refining the Infected at the Start

[High Intellectual Game] + [Psychological Warfare] + [Dark Reality] + [No Virgin] + [No Harem] The enforcer I buried with my own hands rose from the grave and knocked on my door. In this doomsday contaminated by "foul gas", survivors will become infected once they are injured. And my sister with scarlet eyes was shivering in the corner. I killed the law enforcers who came to my door, but it attracted a more terrifying existence. They said that my talent was unknown and that I was a precious anti-pollution body. But I know that the way they look at me is like looking at a perfect tool. Now, they want me to personally capture the infected person I want to protect the most, my sister. I stroked the "Dao Derivative Technique" in the sea of ​​​​consciousness that could swallow up filth, looked at the dry well in the backyard that was connected to the source of pollution, and made a crazy decision. Since this troubled world cannot allow me to wait, I will use this dirty soil as the foundation to become an immortal.
