Judge Li Qing was reincarnated as Zhang Zangqi, a descendant of Daxia Xungui. She originally wanted to live a life of ease, but because of the injustice of the country girl Liu Yaer, she boldly challenged the family. Overnight, he fell from the clouds to the dust and was trapped in the prison of Dali Temple. What awaited him was a bowl of rice with his head cut off.
In a desperate situation, he bit off his fingertips and used blood as ink. What he wrote was not a redress of grievances, but a "letter of surrender" dedicated to the emperor - he was willing to transform into the sharpest and most ruthless knife in the empire and cut off all dissatisfaction.
The emperor, who knew everything, gave him a chance to escape death. So, he stepped through the conspiracy of imperial examination fraud, stepped on the bones of his old enemies, and walked step by step towards the center of power. He gathered young people living on the streets and trained Ah Fu, a mathematical genius. He used modern knowledge as a weapon to maneuver on the chessboard of power.
However, just when he thought he could protect everything with his wisdom and law, his old enemy Lu Chengsi laid a plan to kill him, and the genius boy Ah Fu was bleeding on the streets just for a ledger in his hand. This became the first death of Zhang Zangqi's idealism - he realized that in this dark age, the law could not save the people he cared about.
In the boundless hell, his fiancée Song Qingxian, who had a fate with him in his previous life, shone like a ray of light into his cold life. "If an Afu falls, if thousands of people who understand mathematics and science and understand right and wrong stand up, his death will not be in vain."
This time, what he wants to steal is no longer just justice in a certain case. What he wants to steal is enough to reshape the foundation of the empire, the fire of civilization.
