Modern young man Qiu Shengjie accidentally passed through his soul and became Tang Congxin, the third son of the Prince of Daqi. He turned out to be an abandoned son who was cruelly exchanged by his biological parents and imprisoned in Fangzhou Cicada Temple for more than ten years. He was trapped in the double dilemma of secrecy of his life experience and lack of emotions. He could only rely on the knowledge reserves of the time travellers, secretly practice Qi training, silently accumulate strength in the desperate situation, and wait for a turnaround. In the later years of the empress's life, an imperial edict called him back to the capital, but something unexpected happened on his way back - the Tiele tribe in Shuobei kidnapped him. The leader Ashina Ying tried to use his status as a prince to force him to the position of khan, turning him into a puppet against the imperial court and disrupting the situation of the court. In a desperate situation, Tang Congxin did not give in. Instead, he turned into a secret agent of the imperial court. With modern management strategies and meticulous intelligence methods, he struggled to deal with the enemy's disguise and his loyalty to the emperor. He worked step by step to help the imperial court stabilize the northern border and win a breathing space for Daqi. After returning to the capital after going through hardships, the turbulent battle for imperial power is the real test. The royal family is riddled with shackles of corrupt rules, brothers who covet the throne are eyeing the throne, the empress is about to expire, and the countdown to the throne has entered a fierce battle. Faced with his biological parents, Prince Ji and his wife, who had no affection for each other, and the covetous forces in the DPRK, Tang Congxin used his scheming strategies that transcended the times and his precise insight into the current situation to resolve fatal crises many times, and gradually gained the empress's absolute trust, and was appointed as the emperor's grandson. In the end, he completely overturned his hypocritical and cold-blooded biological parents. After the death of the empress, he used modern innovative thinking to reorganize the government and eliminate old abuses. He successfully ascended the throne and determined to create an unprecedented prosperous age.
