Su Wuji, the top demon-slaying master from time-travel, adheres to the belief that "slaying demons also kills beasts in human skin", and with his illustrious military exploits, he went from Jiangcheng to Wangcheng to take over as the captain of the Tianshu Army. He cut off the centuries-old cycle of sacrifices of the Shenyu family, uncovered the collusion conspiracy between the Dark Abyss and the Vampires behind the Black Seal Disease, killed the evil Vampire Captain in public, annihilated the decadent families who colluded with demons with thunder, led the troops in the north to defeat powerful enemies such as the Frost Lord, and gradually tore apart the network of dark forces in the royal city, always practicing his original intention of slaying demons and eradicating traitors.
