Private setting, no historical reference!
Gentle, kind (pretended) sufferer & scheming yandere
In the twenty-fifth year of Tianhe, Emperor Zhan of the Sui Dynasty made the second prince Song Qingfeng the crown prince. The state of Ji establishes the elders but not the young, and establishes direct descendants but not concubines.
All the ministers thought that the eldest prince and the second prince would fight to the death for the throne.
Even Song Qingfeng thought so, but Song Huyu didn't.
Because Song Huyu had a little-known secret: Song Huyu was not the biological son of Emperor Zhan of the Sui Dynasty.
In order to keep this secret, he first planned to kill his mother-in-law, who was deeply in love with her, and then harmed her mother's family. He even succeeded in getting Song Qingfeng to join forces with him to kill Emperor Zhan of Sui.
"Concubine, you said it yourself to cut the grass and get rid of the roots..."
Every step Song Huyu took was successful, but he missed one step...
"You... When did you know..."
"Brother, guess..."
This article will be a little cruel, because my ending is:
"You must wake up from a deep dream, and pay off your sins so that you can end."
Because the ending should be changed, after all, it's not finished yet.
Purpose: Happy every day
