Cheng Ci, the new emperor of the Dayong Dynasty, has a vast empire, but is a complete "iceberg" workaholic. He unexpectedly awakened the "National Games Deduction System" and could see countless possibilities for the country's future, but he could not see his own emotional line. Above the court, the green tea-shaped concubine Liu Ruyan appears to be weak and pitiful, but in fact she is trying to lead the emperor into the abyss of pleasure in order to evade the imperial power. Cheng Ci was unmoved. He only reviewed memorials, planned people's livelihood, and deduced national policies every day, vowing to create an eternal prosperous age. However, the daily healing style gradually went awry. Every calculation of Liu Ruyan was solved by Cheng Ci using cold data and logic, and instead became an interesting game between the monarch and his ministers. Under Cheng Ci's absolute rationality and Liu Ruyan's ultimate disguise, the Dayong Dynasty moved towards a warm future that no one expected. This is a story about how the emperor used the golden finger of "planning the future" to heal his family, country and world under the appearance of an iceberg.
