Xichang Yuhuatian Is Going Crazy in the American Police Circles

I, Yu Huatian, the governor of Xichang, woke up and traveled to a modern and beautiful country. He became a marginalized expatriate policeman. But after traveling through time, why is it still...

In his previous life, he was able to frighten the civil and military officials of the entire dynasty, and in this life, he can make the Western police force bow to its knees. "A helpless serial killer?" Yuhuatian turned the pen carelessly and showed a warm and jade-like smile. "Give me three days." Three days later, the killer was so tortured that he knelt in front of the police station crying and surrendered. The detective was stunned. "You... How did you do it?" Yu Huatian flicked his sleeves, his smile not reaching his eyes. "It's just some old craftsmanship from Dongchang."
