Wuxia Crossover: Starting Out as the Princess's Scapegoat

Luo Nan is an officer of the Divine Constabulary. One day, he is drawn into a murder case at the Princess's residence and made the scapegoat. To protect himself, he activates the “Master Detective” System and is forced to navigate the tangled worlds of court politics and the jianghu. But the deeper he investigates, the more alarmed he becomes: he seems to have long been part of someone else's “cultivation technique,” and the real culprit is far more powerful than he ever imagined.
