The Republic of China was in troubled times and warlords were separatist.
Zheng Jiuyuan, a warm-hearted man who seems harmless to humans and animals, is actually a poisonous snake of thousands of people crawling around in the world.
He was once expelled from the school by his master because he said that he "cannot achieve great things if his heart is not ruthless and his hands are not ruthless".
But when his master died tragically and mysteriously three years ago while investigating the shocking conspiracy of warlord Marshal Zhao, Zheng Jiuyuan realized that his master was trying to prevent disaster for him.
Now, under the pseudonym Zheng Nuan, he takes the initiative to get close to Marshal Zhao. With his superb skills, he has become Marshal Zhao's most trusted aide.
But Marshal Zhao didn't know that this young man who always had a gentle smile on his face was secretly weaving a huge web.
What he wanted to do was not only to avenge his master, but also to expose Marshal Zhao's conspiracy of colluding with the Japanese pirates to sell the country.
One card can win you a thousand taels of gold.
A scam that can subvert a warlord.
But as Zheng Jiuyuan got closer to the truth, he discovered that his master's death was far more complicated than he imagined. Even, Master left behind a deeper mystery——
Is the person who taught him his skills dead or alive?
