I'm Bao Qingtian. Why Do I Have a Northeastern Accent When I'm Investigating the Case?

Zhao Tiezhu, a modern Northeastern talk show actor, accidentally traveled back to the Jiayou period of the Northern Song Dynasty and became the "selfless" Bao Qingtian and Bao Zheng! He thought he would live the hard life of feudalism with a straight face every day, but he stopped pretending and turned the lobby of Kaifeng Mansion into a Northeastern dialect talk show! Facing the scumbag Chen Shimei who refused to admit his defeat, he was shocked and said: "You kid are still trying to bullshit me, aren't you? How can you be so good at pretending!" Facing the corrupt officials in the court, he fired a barrage of attacks that made everyone in the court doubt their life. Not long after, the aloof Zhan Zhao and the gentle Gongsun Ce were all infected, and they all started to say "What's wrong, big brother" and "You're talking nonsense"!

When Northeastern-style "fraud" techniques and modern logic encountered ancient serial strange cases, the civil and military officials of the entire dynasty were horrified to discover: Although Bao Qingtian's painting style was completely off-kilter, why was his crime detection rate getting higher and higher? !
