At the end of the Song Dynasty, the emperor passed away. Princess Zhao Qingning was forced by powerful ministers to succeed to the throne, and she had to marry a man she had never met.
She escaped.
In the forest on a rainy night, she met Shen Zhao, a chivalrous woman in black who was covered in blood and whose sword was as bright as lightning.
That night, Shen Zhao saved her life.
Zhao Qingning grabbed this beam of light and tried his best to keep her by his side. The two became sworn sisters and agreed, "You will protect me and I will protect you."
But the powerful minister didn't give her a chance.
On the night of the palace coup, Shen Zhao pushed her into the secret passage and turned around to face thousands of troops.
"Live!" - These were the last words Shen Zhao left for her.
The stone gate of the secret passage suddenly closed, and Zhao Qingning cried for three days and three nights.
In the next three years, seven guardians were sent to the palace, but she rejected them all. "Shen Zhao will not die. She promised me."
Until the flying pigeon returns.
There was only one line in the letter: "Wait until I come back."
