In the ninth year of Kaibao's reign, on a snowy night, Song Taizu Zhao Kuangyin died mysteriously. The sound of the shadow of a candle and the sound of an axe will remain a mystery for eternity. A few years later, a seemingly inconspicuous case involving medicinal materials in the palace involved Mu Chen, a junior official in the Ministry of Punishment. He keenly discovered that there was a fatal time difference in Queen Song's reaction on the night Taizu died.
Following this subtle crack, Mu Chen uncovered a truth that subverted cognition: history is carefully "calculated". A hidden organization called the "Destiny Division" is in charge of the "Heavenly Secret Algorithm" that can deduce the rise and fall of the country's fortunes. Taizu's death was actually the "optimal solution" deduced by an algorithm to avoid a military disaster that would destroy the country. And he himself is just a preset variable in this huge calculation.
When Muchen decided to make a desperate move and announce the tampered truth to the world, he was shocked to realize that what he thought was a "counterattack", from the beginning of the investigation to the discovery of evidence, had already been written into the script by the Division of Destiny, and became the final sacrifice to cover up another deeper and darker secret.
How many calculated causes and effects are hidden in the cracks of history books? And for that step that belongs to him, has the ending already been written?
