Hou Ming, a graduate student in the Department of Modern History, traveled to an ancient dynasty in an archaeological accident and became an unknown person who was about to be sacrificed by his family. With a knowledge system that transcends the times, from modern medicine, engineering technology to military strategy, he has gained an information advantage that overwhelms the ancients. When he first arrived in ancient times, Hou Ming faced oppression and persecution within his family, and was forced to use modern wisdom to survive. He skillfully used medical knowledge to treat the powerful and gain asylum; he used engineering technology to improve people's livelihood and win the hearts of the people; he relied on historical prophets to avoid political traps and gain a firm foothold in the court. As his power grew, Hou Ming began to implement reforms, which touched off vested interest groups and attracted joint pressure from powerful officials in North Korea and China. When foreign enemies invaded and the country's survival was in danger, Hou Ming was ordered to use modern military knowledge to organize resistance, but found that his behavior of changing history triggered an unexpected butterfly effect. He must choose between saving the country and maintaining its historical trajectory, while facing two completely different suitors - one is the daughter of a conservative aristocrat, and the other is the daughter of an emerging businessman who supports reform. In the end, Hou Ming not only successfully repelled foreign enemies, but also promoted a series of reforms and created a new era, but he also paid the price of losing close friends and changing the trajectory of history. He grew from an unknown person to a generation of "Chaos God Emperor", reshaping the ancient world with modern wisdom.
