I, Shen Changfeng, Only Rely on My IQ to Solve Mysterious Cases.

During the reign of Renzong in the Northern Song Dynasty, in Bianliang, Tokyo, the most virtuous place in the world, strange cases in secret rooms occurred frequently, the dead were mysterious, and the scene was unsolved, which made the Kaifeng Mansion anxious. In the intertwining of the powerful and the market, Shen Changfeng, a commoner genius who had been disheartened by his family's injustice, was unexpectedly used by Bao Zheng, the selfless governor of Kaifeng, with his ultimate insight into the organs, architecture, and forensic science of the Song Dynasty, as well as his logical reasoning ability that surpassed ordinary people. He has no golden fingers. He only relies on his talent and perseverance. He partners with Liu Ruyan, an independent and courageous female detective who is proficient in autopsy. He deeply studies the details of Song Dynasty's ancient style and gradually deciphers the "Song Dynasty craftsman's secret room" that combines the "secret skills of the craftsman", revealing the amazing ingenuity behind it. However, every time the truth is revealed, a deeper conspiracy and a more powerful man behind the scenes are involved - a mysterious organization calling itself "Shadowsmith". They use the ancient and taboo secret technique of "mechanism to lock the heart" to create the perfect crime, and even intend to revive the legendary ultimate power that can control people's hearts. What is even more shocking is that the old case of Shen Changfeng's family being wronged is actually inextricably linked to this dark force.
