Zhao Yiming, the top academic in 2025, accidentally traveled to the Tang Dynasty and became Qin Lang, the notorious patricide in Heyang County. As soon as he opened his eyes, his throat was choked with chains and he was taken to the court to be executed late!
In a desperate situation, he relied on his criminal investigation knowledge that was beyond the times to prove his innocence, but he was shocked to find that behind the death of the original owner, there was actually a long-lost cultivation technique involved, and his academic brain, accustomed to advanced mathematics and quantum physics, happened to be an excellent container for practicing this technique!
After being forced to join the mysterious Criminal Investigation Department of the Tang Dynasty, Qin Lang formed an investigation team with Shangguan Qian, a judge who was full of wits and whose identity was a mystery, and Murong Wan, a coroner who was cold but highly skilled. What they face is no longer an ordinary murder: the princess died mysteriously on her wedding night, the Persian mission had hidden evil intentions, and the strange three-eye mark appeared frequently... All clues point to a mysterious organization that believes in evil gods and is proficient in poison illusions - Netherworld Dao!
