Dayin has been passed down for thousands of years, and it hides a bloody secret: every hundred years when there is a disaster during the sacrificial period, the emperor will be sacrificed to the destined prince, using the power of the sacrificer to quell the natural disaster, and then massacre the sacrificial clan to avoid future troubles.
The gentle and forbearing prince Shen Wusi was born to be a sacrifice. He saw through the cannibalistic nature of the imperial power and wanted to overthrow the decadent ancestral system. On the other side was the censor Hanqi who lurked in the court and was burdened with the blood of the sacrificial clan. He spent twenty years as a hypocrite and planned to restart the ancient contract between humans and gods.
One person follows the human path to revolutionize the imperial power, while the other guards the sacrificial path to repay the old contract. The court plans every step, and disasters occur in Kyushu. From the chess game in the East Palace to the two points in the world, they are each other's sharp swords and the only confidants. They go against each other on the road of life. In the end, they will join forces to cut off the thousand-year cycle of sacrifice and reset the old and new order in the world.
Intention: There is no absolute justice or evil. Standing determines right and wrong. Common people are the ultimate yardstick. Hatred is never the truth. The suffering of reincarnation comes from the obsession passed down from generation to generation. However, rules are shackles and can also be rewritten by people.
