Cao Yuan was once an upstanding young man in modern society, a physics doctoral graduate of Jinling University. After an accident, he transmigrates to the ancient Great Hao Dynasty and becomes a poor scholar from a humble family.
His golden finger is his knowledge of physics, chemistry, and technology, which helps him quickly adapt to this unfamiliar world. Shortly after arriving in ancient times, he meets the kind and clever Yang Yuqing, and the two support each other.
Cao Yuan knows that the road to success starts at the bottom. He uses modern knowledge to improve farming tools and boost agricultural productivity. He founds a trading house and uses modern market principles and business strategies to crush the backward commercial rivals of the Hao Dynasty.
Later, when foreign enemies invade, he volunteers for the army. Starting as an ordinary soldier, he steadily builds an illustrious military record and becomes a legend in the ranks. The Great Hao emperor is incompetent and indulgent, spending every night in revelry and neglecting state affairs. Corrupt ministers seize power, turning right and wrong upside down. Cao Yuan enters officialdom and makes a name for himself with his talent and modern management principles.
As power struggles in government continue, Cao Yuan realizes that changing the country's fate requires greater control over the machinery of state.
He begins laying plans in the military, repeatedly defeating foreign enemies with his modern strategic thinking until he becomes a power in his own right.
As his influence grows, his ambition becomes clear. His ultimate goal is to ascend the throne and become emperor.
With Yang Yuqing at his side, Cao Yuan overcomes one hardship after another and ultimately fulfills his ambition, formally ascending the throne.
Cao Yuan and Yang Yuqing's love grows ever deeper along the way, as they join hands to write a legend of rising from humble beginnings.
