It rained all night in Lin'an City.
Yao Shichuan stood in the dilapidated courtyard of the Liu family, looking at the letter of help that was about to be sent, knowing that he had no way out.
This is a story about "choice".
A soul from later generations traveled through the troubled times of the Dajing Dynasty. He could have been a rich man and live a happy life; he could also have been a powerful minister and mend the sky with one hand.
But what he ultimately chose was the most dangerous path - to survive in the cracks between imperial power and prime ministerial power, and to dance on the balance of love and ambition.
He used the Liu family's trade routes to weave an intelligence network that covered the world;
He used Lin Hongyu's military power to forge a sharp sword that pierced the darkness;
He used the legend of "Qilin'er" to pave a ladder for himself to the pinnacle of power.
When all the dust settled, he stood on the top of the Forbidden City, overlooking the thousands of miles of mountains and rivers.
Looking back on the past, those vows made in the rainy night of Lin'an and the blood shed in the wind and snow at the border have all turned into the most colorful strokes in the history books.
"In my life, I, Yao Shichuan, do not seek to be famous forever, but I seek to be worthy of my heart and your honor."
