Great Sui Dynasty Hegemony

[History Essay] Sanwu youth traveled to the Sui Dynasty and became Yang Guang's grandson Yang You, and started an alternative life from then on. He is an alternative in the eyes of everyone, a black sheep who instigates relations between ministers. As the grandson of the emperor, he only has the fiefdom of Chang'an. Yang Guang ordered him never to return to Luoyang. Yang You, who has modern thoughts and a sense of crisis, is prepared for danger in times of peace, preparing for war in Chang'an, and taking precautions. When Yang Guang was dying, he exclaimed: "I regret not listening to my grandson's loyal words!" After Yang Guang's death, the ministers elected Yang You to succeed him. Ascending the throne in danger and surrounded by enemies, Li Yuan wanted this thirteen-year-old baby to become his plaything, a puppet. But things didn't go as planned, and Yang You returned to Luoyang with a million-strong army. The heroes were all shocked and their livers and gallbladders were about to burst!
