My name is Zhang Yin, an ordinary scholar in the late Southern Song Dynasty.
That year the Yuan army went south, and the whole village thought I was going to die.
As a result, I survived and saved seventeen lives.
Later, I entered Lin'an Prefecture School, and the Imperial City Department arrested me everywhere.
I read a letter to Mr. Jijiu, and he said, "I will protect this child."
Later, when he was admitted to the Imperial Academy of the Yuan Dynasty, Kublai Khan personally summoned him.
"What is your opinion on the general trend of the world?"
I said, "Your Majesty, do you want to hear the truth or lies?"
He smiled and asked me to stay as an official.
This time, it will be ninety years.
On the surface, I was the most obedient Han official in the Yuan Dynasty, helping them build canals, fix calendars, and teach the prince.
Secretly, I buried nails in every government decree, dug pits for every battle, and hid private goods in every history book.
Forty years later, the finances of the Yuan Dynasty collapsed, and it was me who tampered with the ledgers.
Sixty years later, when the Red Turban Army rebelled, it was I who gave them the gunpowder formula.
Eighty years later, Emperor Yuan Shun escaped from Dadu, and it was I who opened the city gate.
No one knows these things.
In their eyes, I am just an old Taoist priest who has lived longer.
In the year when the Ming Dynasty was established, Zhu Yuanzhang came to visit him personally:
"Old sir, your life is worth it."
I smiled and said nothing.
Later they gave me a biography and called me Zhang Sanfeng.
It is said that I travel all over the world, and the dragon never sees its end.
He said that I have lived for two hundred years and am an expert.
In fact, I did one thing -
In that era of wars everywhere, live, watch, and wait.
Wait for a peaceful world.
