Great Sui Dynasty

In the last years of Emperor Kaihuang's reign, the Sui Dynasty had not yet shown signs of decline. Prince Yang Yong was lustful by nature, loved luxury, and was subject to suspicion. Jin Wang Yang Guang was in charge of Yangzhou, his style was simple and he worked hard to govern. Two dragons compete for the legitimate son, and two sons fight against each other. At a time when the situation is changing, Fan Yao, a college student in the 21st century, comes to this world. More than ten years later, the people are about to rise up. Is it the wandering clouds and wild cranes that live alone in isolation? Or follow history and follow the Li family? Or help the Sui Dynasty turn things around? Or... Become a prince and aspire to dominate the Central Plains?
