Great Qin Detective: I Want to Be Made a Marquis

Delivery boy Qin Chuan's soul traveled through the Warring States Period, and when he opened his eyes, he was already on death row for rape. No system, no plug-ins, just modern thinking and knowledge of police movies. In order to survive, he was forced to work as a "temporary criminal investigation worker" in Handan County, where Qin's laws were strict. From using the form of blood stains to solve serial butcher cases, to using micro-expressions to see through aristocratic patricide plots, he used dimensionality reduction and criminal investigation methods to carve out a way out in the troubled times of the Warring States Period. The mixing of military rations with sand, the smuggling of salt and iron, and the many spies involved in Jing Ke's assassination of Qin... Each case hides the torrent of history. From being a slave to be beheaded to being a prince of Qin, he saw the overthrow of the six kingdoms and participated in the construction of the empire. This is a thrilling adventure that uses modern criminal investigation technology to dissect the Qin Empire.
