Start with a Cat, I Am a Dandy in the Tang Dynasty

A modern academic tyrant accidentally traveled across the Tang Dynasty and became the underappreciated Erlang Li De in the family of Wei Guogong Li Jing. The scumbag best friend who traveled through time with him turned into a black cat. Not only can this cat speak human language, but it also has astonishing strength. The first-generation heavenly master Yuan Tiangang even gave it immortality! Others traveled through the system, but he traveled through time and picked up a top-notch dog-headed military advisor who was a red stick thug. The undercurrents of the Zhenguan Dynasty were turbulent, there was a game over the throne, aristocratic families were running rampant, and conspiracies were everywhere. One man and one cat joined forces, and Li Dejiang stepped into the Xiuyi Building, the most mysterious secret investigation agency in the Tang Dynasty, and became the governor of the Xiuyi Building, which was feared by both the government and the public. Solve unsolved cases, investigate plots, uncover secrets, and suppress powerful families. Originally he only wanted to be a dandy general's disciple, but he rose up all the way to be in charge of life and death. The black cat stepped on the memorial and sneered: "Whoever dares to cause trouble, I will expose his background in public!"
