The Years I Spent Solving Crimes in the Demon Suppression Division

Shen An traveled through time and became a minor official in the Demon Suppression Department of the Great Xia Dynasty. Others rely on talent for cultivation, but he relies on science for cultivation - physics to overcome thunder tribulations, chemistry to change spells, and psychological profiling to solve strange cases. On his first day on the job, he was unjustly accused of being the murderer of his family. His immediate boss said: If you prove your innocence within three days, you will be beheaded. Shen An looked at the bloody knife in his hand and sighed: "Want to harm me? Okay, then I'll catch you all out." This is a story about a man who graduated from a police academy and traveled through time to solve strange cases and reach a high position. It is my destiny that my talents will be useful, and I will come back after all my money has been spent!
