The story takes place in the fictional historical dynasty "Zhao Kingdom". The late emperor died, and the young prince Qi Sheng ascended the throne with the assistance of the auxiliary minister Zhao Mu. However, undercurrents surged in the court, and various forces launched a fierce struggle for power. Qi Sheng gradually grew up in the power struggle, from an ignorant boy to a generation of emperors, but he also lost a lot in the process, including family affection, friendship and love. The love-hate entanglement between him and Lu Qingyi, the trust and betrayal between him and Zhao Mu, and the use and being used by Liu Ruyan have all become the price for him to reach the top of power. In the end, Qi Sheng looked down at his empire alone at the top of power, only to find that he had lost his way and had forgotten his original dream.
