Law student Gu Beichen woke up and became a humble master who was convicted and exiled in a small border town of the Daqi Dynasty. In front of us, tyrants are rampant, laws are in vain, and a case of a tenant's "accidental" fall and death vividly demonstrated judicial corruption.
When everyone wanted to wrap up the case hastily, Gu Beichen brazenly tore up the shady story. Modern forensic science is his eyes to see the truth, and evidence chain logic is his sharp blade to pierce hypocrisy. As a humble person, he launched his first challenge to the intricate network of local interests.
However, the road to breaking through is also the beginning of crisis. With his professional knowledge that transcended the times, he repeatedly solved strange cases and became famous. However, he also stepped into a more dangerous whirlpool step by step - he attracted the attention of the eunuch Lu Zhi, the powerful eunuch of the Supervisor of Ceremonies. From then on, he was forced to get involved in the shocking chess game between imperial power, civil servants and eunuchs.
In this cruel world where machinations are blood and laws are garnishes, Gu Beichen has modern knowledge in his hands, using "Da Qi Law" as a shield and procedural justice as a spear. He not only wants to avenge the wronged souls, but also launches the ultimate judgment on this decadent old world. When all the vested interests of the old order join forces to fight back, can he realize the ultimate ideal of "law is greater than heaven" in this era of supremacy of royal power?
