Legend has it that whoever gets the "Stealing the National Policy" can conquer the world. It is not a military strategy, but a shocking secret key left behind by the previous dynasty that can shake the mountains, rivers and dragons.
Yun Shuyue, on the surface, is a well-known organ master in Beijing, cold and dignified; secretly, he is an orphan of the previous dynasty and the leader of the "Qianlin" organization. What she pursues in her life is not love, but to use her machine skills as a blade to steal this decayed country, restore her homeland, build a new dynasty, and practice her philosophy of "making the people rich and powerful through work".
Xiao Zhi, the idle prince who only knows the world in the eyes of the world, is actually the most hidden careerist. He also pursued the "Policy of Stealing the Nation", aiming to eliminate long-standing abuses, clear up the political agenda, and create a new dynasty in which imperial power was supreme.
Under the underground palace, they briefly joined forces for a common goal and shared life and death; above the court, they became each other's most difficult opponents because of their completely different concepts of the ownership and direction of "the world".
This is a competition that begins with conspiracy and ends with ideals. She wants to use all the institutions to rewrite the world; he is willing to use the country as a chess piece to plan the world.
When the chalcedony is finally pieced together and the power of dragon veins reappears in the world, will they choose to fight to the death, or... Hold the chess pieces together and join forces to open up an unprecedented new world?
