The World-Destroying Demon King: Kill Tens of Millions of People, and I'm Leaving

The day I came out of Fengshen Mental Hospital, I heard passers-by mutter: Another one has come in. At that moment, I realized that there was an abyss behind me and the apocalypse in front of me. Kill one person to get one point of adaptability, kill ten thousand people to get ten thousand points of adaptability. Whether they are human or other ethnic groups, they will all surrender to me, and any offenders will be killed without mercy! This novel and its characters are purely fictitious.
