Zeyu, a graduate student in the history department, traveled through time and became an abandoned son of a poor family in Daqi. He failed despite repeated attempts and was ridiculed by his tribe. Fortunately, the ancient mirror has the power of divination, and one hexagram every day can lead to good fortune and avoid misfortune. He relied on this to counterattack the imperial examination, winning three prizes in a row and becoming the number one scholar; he befriended powerful ministers, trained cavalrymen, and promoted new policies. From being an abandoned son who was bullied by others, he gradually took over the power of life and death and became a legend praised by all people.
