Dou Shi Chuanyue Ping Shenme Wo Shi Jiexiaqiu

Someone who has transmigrated as a King or Prince lives an extravagant life basking with power and influence. Then there’s someone who has transmigrated as Sect Master or Leader; well respected with extraordinary skill. Finally the least of them is someone who has transmigrated as a villain; living with a goal of destroying the protagonist, stirring up trouble and making things worse.
Li Changtian, a young man of good pedigree in the modern era, died in the line of duty. But when he opens his eyes... Huh?! I’ve transmigrated?!
People shout and beat him, as he is a prisoner who's committed the most heinous crime! Yan Shu, an inspector who abhors evil, steps on him and with a cold tone says: “Killer, pay with your own life!”
