Justice? It is written by the victors. Evil is merely a disparaging label for the defeated. Born ordinary, Zhang Xiaoyu accidentally transmigrates to the world of pirates. He witnesses the pirates' atrocities firsthand and is horrified, yet powerless to stop them. He is just an ordinary person, trembling beneath the demons' feet, until an angel descends. He will wipe out the demons of this world and change this twisted world...
