After Awakening from the Ninth Life, I Became Emperor

She traveled through time and became the prime minister's legitimate daughter. She was tricked by King Yan into falling into the water and ruining her reputation, and was forced to marry into Prince Yan's palace. She couldn't swallow this breath. On their wedding night, she drugged King Yan and spent the night with the most handsome secret guard. On this night, she planted two seeds: one was the child in her belly, and the other was the beginning of seizing power. King Yan failed to seize the rightful son, so she saved King Yan's life with the gold medal for immunity from death, and used this to escape from the capital and go to the fiefdom of Youzhou. The King of Yan failed to recover and died in depression. The widowed Princess Yan took the system and took root in the precarious border Youzhou. Starting from the people's livelihood infrastructure, she successively defeated foreign enemies such as the Xiongnu and Goguryeo, and won the hearts of the surrounding states and counties. From border autonomy to founding the country and proclaiming the emperor, she finally unified the Central Plains. After unifying the world, she passed on to her son, relinquished power with the secret guards, took a treasure ship to sea, opened up the Maritime Silk Road, established coastal defense and ocean systems, and pushed the territory and influence of the Yan Kingdom to the top of the world. This is not a story about a comeback based on love, but a story about a woman transforming herself from a chess piece into a chess player. Everything she did was to let the ground beneath her feet grow roots that would allow people to stand and live. When a woman no longer relies on anyone's love for her destiny, she has the power to subvert everything.
