He has thousands of miles of land, power over life and death, but he can't trap only one person.
In the eleventh year of Jingming Dynasty, Marshal Bai Chengjin of Zhenbei requested an order to go to Mobei. Emperor Xiao Zeyuan offered his young son as hostage in exchange for his promise. An imperial edict, a child, and a way back have pinned the two people's half-life entanglement on the chessboard of imperial power and old hatred.
Above the court, he blocked all open and hidden arrows for him; in the wind and snow in Mobei, he guarded the border ten thousand miles for him. But what separates them is not only mountains and rivers, but also blood debts, a marriage contract, and the words "back then" that can never be uttered.
He once said: "My sincerity is only given once, and after it is burned, it is gone."
But he said: "Only Mobei, only this person, I have the special permission."
The peaceful and prosperous age praised by thousands of people was bought by him for half his life of loneliness. On New Year's Eve that year, he stood alone under the withered pear tree in the old courtyard of the East Palace and said "Hengan every year" to the sky full of fireworks that no one heard.
