Prince Xuan Lin hurriedly ascended the throne after his father died suddenly, but he knew nothing about the secret of the Dragon Throne. The first time he sat on the throne, he suffered an invisible backlash, vomited blood and fell into a coma, and was deemed "morally unworthy". At the time of crisis, Su Yan, the daughter of the late Taifu and a former imperial official, appeared with half a torn volume of the "Instructions for the Use of the Dragon Chair". Only then did Xuan Lin realize that to secure his position, he literally needed a "guide".
Inside, the Queen Mother hangs the curtain, the powerful ministers control the government, and the brothers and vassal kings are watching with eager eyes; outside, there are powerful enemies invading the borders, and disasters occur frequently. Xuan Lin must, with the help of Su Yan, study strange clauses in the guide such as "how to sit to induce the luck of mountains and rivers", "how to review memorials to soothe the spiritual veins of the four directions", "what kind of sacrifices can repair the cracks in the national destiny" and other strange clauses, while struggling to survive in the real political strife. He must use the limited "authority" granted by the dragon throne to fight wits and courage with the enemies inside and outside the court. At the same time, he must find the missing second half of the guide, repair the Sheji Formation, and truly master this imperial treasure. This is an extremely dangerous "Novice Emperor Survival Game" on the Dragon Throne, involving life and livelihood.
