This is no ordinary time travel novel. The protagonist is being hunted at the beginning, and the system does not provide cheats, only knowledge. He relies on his brain to fight his way out of desperate situations. Every victory is justified and every reversal is unexpected.
Wu Zetian was not a simple evil person. She has killed many people and betrayed many people, but she has never betrayed her own son. Mother and son are separated by imperial power, conspiracy, and thousands of mountains and rivers, but they are separated by blood. This is not a palace fight, this is a mother who wants to see her son one last time before she dies.
The story takes place during the period from Emperor Gaozong of the Tang Dynasty to Wu Zetian. Major historical events such as the Tubo invasion, Princess Taiping's rebellion, and Li Xian's restoration will all appear. The protagonist is fictional, and his story grows out of the gaps in history. You will see how a modern person can use the wisdom of a thousand years later to change the fate of a thousand years ago.
