Xie Qingci, a down-and-out hostage, bears the hatred of his family being wronged and exterminated, and is forced to survive in the cracks of the great powers' courts. On the surface, he is as docile as a sheep, but in reality he has a deep mind. He uses his extraordinary resourcefulness and Pei Junhan's overwhelming power to work step by step and tear apart the hypocritical mask of his old enemy with his own hands. The powerful minister Pei Junhan, known as the "crazy critic of the prime minister", is vicious and ruthless. He originally regarded Xie Qingci as a disposable plaything, but through repeated battles of wits and extreme pulling, he was attracted by the tough backbone underneath the cold appearance. The two went from using each other for their own purposes to joining forces to break the situation, and finally uncovered the ugly conspiracy of the imperial power at the peak of power. On the day when Xie Qingci's injustice was overturned, the former arrogant and crazy power minister was finally willing to curb his sharp claws and become the only loyal dog in front of the proton.
