Lu Jinxing was once the son of a count on the border of the empire, but due to a palace conspiracy, he was labeled a rebel and sent to the ninth level of the legendary dark prison where there was no return. The most vicious criminals are imprisoned there, and countless geniuses and hopes are buried there. Everyone thought that Lu Jinxing was just a trash that could be trampled upon, but no one knew that there was a dark star core from ancient times sleeping in his body. During a near-death torture, the seal broke, the power of Starry Night awakened, and Lu Jinxing embarked on the road to rise from the deepest depths of the Dark Prison. From a prisoner to a prison king, from an outcast to a border lord, from a judge to a judge of the empire, he will use the dark night as his curtain and the stars as his blades to kill his enemies, reshape order, and establish his own Starry Night Throne.
