Story introduction: During the prosperous period of the Tang Dynasty, under the glamorous appearance of Chang'an City, evil spirits breed. Yu Chijin, a delinquent who once witnessed his comrades being slaughtered by monsters on the battlefield in the northern border, survived but was stigmatized, wandered around the market all day long, paralyzing himself. However, a series of bizarre mummy murder cases made the lingering evil image in his eyes clear again. He was involved in the Demon Suppression Department, a mysterious government agency designed to deal with strange things. Teaming up with his cold-faced boss Pei Xuan and the knowledgeable female case officer Su Qingshang, Yu Chijin was forced to regain his instinct of killing evil spirits. As the investigation deepened, he discovered that these murder cases were not isolated cases, but pointed directly at a huge conspiracy to overthrow the Tang Dynasty. The core of the conspiracy was actually closely related to the "it" that made him lose everything on the northern battlefield. In order to take revenge and protect this city full of fireworks, Yu Chijin must face his inner demons and uncover the dust-laden truth.
