In the Great Xia Dynasty, the imperial power was strife. The seventh prince Li Chen's mother and concubine died young, and they were not favored since childhood. In order to protect himself, he pretended to be stupid and became a "waste prince" that was ridiculed by everyone in the government and the public.
Until a tragedy that killed his family pushed him into the abyss - he was falsely accused of murdering an important official in the court, and was thrown into a prison to be executed on a later day.
In a desperate situation, the [Major Case Investigation System] that had been dormant for many years was suddenly activated!
Case reconstruction, clue analysis, deduction simulation... Li Chen was talking and laughing, finding out the real murderer in public, and shocking the court with irrefutable evidence!
Emperor Longyan was delighted and gave him the post of imperial envoy to solve the case. The princes and nobles who had ridiculed him in the past changed their faces. Even Su Qingying, the daughter of the prime minister who had scorned him, could not help but be shaken by his amazing talent.
