Sui Dynasty: My Grandfather Is Emperor Yang of Sui Dynasty?

At the end of the Sui Dynasty, the world was in chaos, with heroes and wars everywhere. Jiangdu City, by the Grand Canal, ten years after Yang Xiao traveled through the Sui Dynasty, the system was finally turned on. He was about to start from scratch and start a big business. An old Yangtou suddenly told him: Sun thief, I am your grandfather, the current emperor, Yang Guang! "Ah? You are the Great Hun Lord, Emperor Sui Yang!" "You dare to say that I am a foolish king?!" "I don't think you are too faint, but the history books were changed by Li Er, and you became a faint king." "Who is Li Er?" "Li Yuan's second son, your eldest cousin and nephew, and the future emperor!" "Come here, arrest Li Er!" "Grandpa, if you give me the throne, he won't dare to rebel. I promise to write you an emperor through the ages!"
