Tang Congxin, a modern young man, passed through his soul and became the fake prince "Tang Ye" who was subcontracted by the Prince of Ji and his wife and imprisoned in a border temple. He lay dormant for ten years, practiced martial arts and read extensively, just to change his fate against the will of heaven. On the way to be summoned back by the empress, he was kidnapped by Shuobei rebels and forced to become a puppet khan. Faced with a desperate situation, Tang Congxin relied on his wisdom and historical knowledge that transcended his times to make an astonishing move: he obeyed the rebels on the surface, but secretly contacted Helan Raorao, the imperial emissary and leader of the Blackbird Guards, and became the imperial court's "dark blade" inserted into Shuobei. He cleverly used a series of tricks to help the court quell the border troubles and returned to Beijing with his achievements. However, the capital city is the real dragon's pond and tiger's den. His biological parents wanted to get rid of him quickly, the powerful officials in the court regarded him as an alien, and the contenders for the throne were eyeing him. Using modern management thinking and game theory as weapons, Tang Congxin repeatedly made plots in the court to break the situation, and worked step by step. Not only did he win the appreciation of the empress and be made the emperor's grandson, but he also personally sent his cold and heartless biological parents to a dead end. Eventually, he ascended to the throne and vowed to surpass Tang Xuanzong's ambitions and create an unprecedented prosperous age.
