Once traveling through the Tang Dynasty, Pei Jingzhao became Li Shimin's adopted son, and unexpectedly awakened [the system that makes you stronger when solving crimes]!
While others relied on torture to extract confessions, Pei Jingzhao relied on chemical experiments, trace identification and criminal psychology.
The Turkic prince died suddenly in the secret room? Pei Jingzhao exposed the "bloody ghost book" trick on the spot.
Princess Changle disappeared mysteriously? Pei Jingzhao went straight to the ghost market in Chang'an and uncovered a shocking trafficking network.
Wei Zheng killed the prince's wet nurse? Pei Jingzhao broke up the conspiracy in court and made the real murderer kneel down and confess his crime.
The Dangxiang clan rebelled, the Tuyuhun envoys set up a deadly trap, the Tibetan prime minister wanted to kidnap Pei Jingzhao back to the country, and the prince forced the palace...
Li Shimin: "Please come out, the Tang Dynasty can't survive without you!"
Pei Jingzhao: "There is no problem in solving the case, and there is no need to talk about the marriage - unless you confess your crime first?"
