Zhao Xiaofei unexpectedly obtained a jade pendant that allowed him to travel back and forth between the Ming Dynasty and modern society. Do you think he'd overthrow the Ming Dynasty and become emperor himself? Do you think he'd help the Ming Dynasty defeat the barbarians and the bandits? I can only scoff at that!
He only wanted to make money, nothing else; it's good to know one's place. However, fate plays tricks on people. By chance, he became Emperor Chongzhen's son-in-law. He had no choice but to flee south with the princess. Under the power of destiny and love, he established Zhu Cijiong as emperor. When Zhu Cijiong died from illness, he reluctantly let the princess become empress, while he himself became the Regent of the Great Ming.
Afterward, he eliminated the bandits, killed the Manchus, and unified the world, but you wouldn't expect the final ending.
