I Solve the Case While Others Refine Their Energy

[No system + crime-solving upgrades + hard-core suspense + temple arena + high-energy reversal + online IQ] A modern criminal police officer travels through the fantasy world, but becomes a low-level woodcutter? When a serial murder case framed him as the murderer, Qin Chen smiled—— Compete with me in solving crimes? Wu Zuo was still relying on the "Qi Detection Technique" to make wild guesses, but I identified the murderer from his footprints at a glance: He was six feet four inches tall, lame, and thirty-three years old! Xuanzong used tracking techniques, and I can predict by criminal profiling that he will kill someone again within three days! The Xuanjian Division has an order: Anyone who solves a major case will be rewarded with skills, magical weapons, and money. From then on, while others meditated and practiced, I solved crimes and upgraded—— Solve a case, obtain the Hongyin Ring, and rise to the third level of Qi Refining; Solved three cases and was promoted three levels in a row, from County Lieutenant to Dali Temple Shaoqing! From a pariah to a master of the four extremes, he begs to be accepted as a disciple. Use modern criminal investigation techniques to crush the entire fantasy world! But when he reached the top, he discovered—— Every case he solves points to the legend from thousands of years ago.
