During the Daqian Dynasty, Murong Entropy, the king of Northern Liang who guarded the northern border, possessed the strange power of "seeing cause and effect". He can glimpse the past and destiny of all things through touch. An ordinary tribute from a grassland tribe made him see a bloody future of border overturn and dynasty instability. Above the court, the emperor's heart is unpredictable; outside the northern border, powerful enemies are waiting around. Faced with this chess game that involves the fate of countless people, Murong Entropy can only take control of the power, use the knife in his hand to cut off all the black hands reaching out to Beiliang, and use his own way to protect the thousands of miles of rivers and mountains and billions of people behind him.
