The Sand Table

Game producer Lin Xiangyi, in order to protect the secret-laden [Sand Table] simulation mainframe, is pursued by mercenaries. An accident causes his soul to fall into the Northern Yin Dynasty, becoming the orphaned descendant of a wronged family. While fleeing, he saves the assassinated eldest princess, and an imperial edict transforms him into the enviable consort of the eldest princess. The court is turbulent, the consort clan holds immense power, and the emperor's mind is unfathomable. The war sand table system in his mind slowly activates. With terrain deduction, faction simulation, and pros and cons calculation, he sees all the world's chess games clearly. As a consort, he does not indulge in wealth and honor; he sets up intelligence in the marketplace, places chess pieces in the court, gathers old subordinates, reopens old cases, allies with the northern border, and resists the treacherous powerful. One sand table calculates the rise and fall of the world; one lone courage moves the mountains and rivers. From a mere consort of a criminal family to one who holds the tripod and settles the world, every step he takes is steady and sure. — Description from novelcodex.org
