The wedding of the crown prince of the Dayin Dynasty attracted worldwide attention. However, the dowry of Crown Princess Su Yingluo was not a rare treasure, but an incomplete and taboo-ridden half of a solitary tomb outside the royal cemetery. This shocking move was like ice water pouring into boiling oil, instantly detonating the government and the public.
Who is buried under this lonely grave? Why is there only half an inscription? And why did she become the dowry of the Crown Princess?
Prince Huangfuchen was furious, but also felt the strangeness and threat hidden in it. He originally wanted to interrogate this mysterious new concubine strictly, but found that strange things happened frequently in the East Palace: the tombs moved in the middle of the night, strange runes appeared, and the ancient secret realm that was sleeping showed signs of being opened because of this "dowry"...
Su Yingluo's arrival is definitely not to seek wealth, but to bear the cruel contract that her family has protected for generations and the blood curse that she cannot get rid of. This half of the lonely tomb is not only proof of her identity, but also a coordinate pointing to the lost truth. It is also a key seal to suppress some kind of terrifying existence that can subvert the dynasty and even the balance of the three realms.
As the investigation deepens, Huangfu Chen and Su Yingluo are forced to join forces and move from the intrigues of the palace to the ancient forbidden land, the secret realm of the netherworld, and the lost realm of gods. They gradually discovered that the so-called struggle for imperial power was just a small prologue in the face of the more distant and majestic ancient grudges and reincarnation of heaven. The secret of the solitary grave is closely connected with Su Yingluo's bloodline, Huangfuchen's fate, Dayin's national destiny, and even a catastrophe that is about to sweep the world.
"Princess" is related to imperial power and wealth, "half a solitary grave" is a strange dowry, - who is buried in the solitary grave? Why is the dowry a grave? What are the palace secrets behind it?
