Former soldier king Xiao Tianren returns from retirement, only to discover that his parents' death was not an accident. The enemy covers the sky with only one hand, and the law becomes their talisman. He took up the law as a weapon. During the day, he was a golden lawyer, using legal provisions to defend the innocent; at night, he wore a ghost mask and used his fists to bury the scum. When the rules are no longer fair, they become the new rules. In the courtroom, there are sharp words; under the dark night, the iron fist is ruthless - he is called the judge, who specializes in dealing with injustices in the world.
