Late Sui Dynasty: Succession to the Throne at the Beginning

Yang Tan was dissatisfied that the author always made the protagonist the son of the Sui and Tang emperors, or even an illegitimate son, so he wrote a series of book reviews. Then... He traveled through time to Jiangdu in the 14th year of the Great Cause, and became the grandson of Emperor Yang Guang of the Sui Dynasty. A rebellion in Jiangdu is imminent and the Sui Dynasty is about to perish. What should we do? Yang Tan: It's not difficult. Can you do something challenging?
