He traveled through time and became Zhang Yun, a student from a poor family. He originally wanted to make a low-key living with modern knowledge, but he was forced to bear the identity of an orphan of the former royal family and embark on the dangerous road of the imperial examination. During the palace examination, the emperor sneered coldly, and everyone in the civil and military court looked down upon him, until he drew a linear regression model and used data to break the situation, which was earth-shattering.
However, the real turmoil began with the sound of a tea cup breaking behind the bead curtain - the eldest princess revealed the secret: "Your Excellency, you also came through time?"
From then on, he was forced to get involved in the turbulent court struggle. Data can deduce people's livelihood and economy, but it cannot solve the mystery of people's hearts; formulas can explain the laws of all things, but they cannot solve the mystery of power. Amidst the torn apart between tradition and innovation, loyalty and betrayal, ideal and reality, he not only needs to hide the mystery of his life experience, but also needs to reshape the court with modern thinking.
This is a story of using algorithms to challenge imperial power and statistics to fight conspiracy. It is also a legend of two time travelers struggling, cooperating and confronting each other in the intersection of time and space.
