Emotion as Weapon

I was born back to the point, three hours before the outbreak of the apocalypse, with the Emotion Value System activated. In my previous life, I was deceived by my fiancée and bullies. In this life, I took online loans and sold all my possessions to hoard supplies. I managed to take revenge on my unfaithful fiancée, kill bullies, and conquer unit buildings, the residential complex, the neighborhood, and even the city. I got to unravel the truth of the outbreak of the apocalypse.
