Jizhen, a cold, restrained, ruthless and taciturn emperor, had been on the throne for three years, but there was an undercurrent in the court. Prime Minister Gu Mingyuan, who looks gentle on the surface, is actually a hypocrite who hides his sword in his smile, secretly forming a clique and coveting the dragon bed. One day, Jizhen accidentally activates the "Destiny Lottery System", and random rewards can be drawn every day - from rare elixirs, peerless martial arts, classics on governing the country, and strange arts. The income from the lottery may seem trivial, but it quietly changes everything in his daily routine of drinking tea, reviewing folding papers, and visiting the Imperial Garden. With the calmness of the breeze and the moon, he used inconspicuous "luck" to dismantle Gu Mingyuan's conspiracy one by one. This is not a bloody conquest, but a story of an emperor using restraint and wisdom to heal the court and the world in the quiet years.
