You're a Cop, So Who Told You to Unleash the Thunder of Annihilation?

[The story takes its time at first, then really takes off after chapter 20!] Spiritual qi revival, upheavals in heaven and earth! In this world, supernatural ability users and demon seeds have appeared. Some become sword immortals like Li Bai, splitting open the gates of heaven with a single strike! Some grow a third eye, allowing them to see through disguises! Beneath the glitz and glamour of the city at night, there is madness, deception, darkness, fighting, and a ravenous feast! Lu Ming is an ordinary police officer in Shanhe Province who transmigrated here and awakened a cheat ability. From the start, he unlocked a top-tier thunder technique through sign-in, and killing monsters could earn him rewards. But this world was just like the one he came from: there were no demons or monsters at all. That is, until a criminal case made Lu Ming suspicious. Then one day, he discovered… In the entire police station… he was the only human!!!
