Traveling through time and becoming a bankrupt in the early Ming Dynasty, Lin Xiao nearly had his leg broken by a knife in a gambling house, but with a "national debt policy" that transcended the times, he fell into the eyes of Zhu Yuanzhang who was visiting privately incognito.
He just wanted to make some money and be a carefree minister, but he unexpectedly stepped into the most dangerous whirlpool of the empire - the East Palace. The emperor's grandson Zhu Xiongying suffered a sudden illness, and the imperial doctor was helpless; the prince Zhu Biao was frail and had a hidden illness. Lin Xiao, who is aware of the historical tragedy, understands that if he cannot save them, the prosperous age of Hongwu will come to an abrupt end.
As a result, in addition to the treasury dilemma and the war on the battlefield, a more dangerous secret war quietly began. He used modern first aid techniques to snatch people from the hands of the King of Hell, used health management to keep the prince alive, and through repeated poisonings and "accidental" assassinations, he shattered the shocking conspiracy that shook the country.
From the market to the palace, from the household clerk to the "state hand" relied on by the emperor, Lin Xiao walked on thin ice between Zhu Yuanzhang's suspicion and favor, Empress Ma's trust, and the trust of Zhu Biao and his son. He not only wanted to enrich the country and strengthen the army, but also wanted to personally create a Ming Dynasty without "Jingnan".
This is a gamble of knowledge, courage and humanity. If you win, you will retire with success and be free in the mountains and seas; if you lose, you will never recover. And the wheel of history has quietly turned behind him...
