Everyone knows that the third princess, Ling Yan, was mild-mannered, mediocre and useless. She was able to ascend to the position of empress only because she first married Xie Linshuo, a general who held a lot of troops to control the country, and then married Sheng Huaijin, the direct son of the Sheng family who was destined to be the queen of destiny. She took advantage of her military power and the support of her family to gain the throne. It was not until the new emperor ascended the throne that the elders of the four dynasties used their merits to persuade her to accept Shen Zhaotan, the direct grandson of the Shen family, into the palace. The defeated princess Ling Zhaoque exposed the old situation in public, saying that every step from her approach to Sheng Huaijin to her win over Xie Linshuo was a conspiracy. Only then did the officials realize that the third princess, who looked most like a salted fish, was the chess player who had hidden the deepest secrets. Facing the imperial sister's questioning, the Sheng family's accountability, the military power test, the meritorious family's pressure, and the secret counterattack of the second princess Ling Zhiwei, Ling Yanci no longer denied his edge. She thought she was seizing the throne in order to keep the three legitimate princesses alive in the imperial power situation that was doomed to kill each other. But after she actually ascended the throne, she realized that survival was only the first step. The Sheng family wants her to become a controllable new monarch, the military wants her to give her absolute trust, the meritorious family sends a beautiful young man to the palace to test the bottom line, and the old subordinates of the two royal sisters are also secretly waiting for opportunities to counterattack. Queen Qing Leng understands all her plans, the unruly general suppresses the military talisman for her, but the new servant is trying to protect himself step by step between his family and his true heart. She wanted to secure her position, and also protect those who were forced to the sword by the imperial power.
