At the Beginning, Emperor Sui Yang Was Asked to Answer the Question. Is Li Yuan the Anti-King?

In November of the seventh year of Daye, Su Qian traveled through the Sui Dynasty. At this time, he awakened the "History Question-Making System"! As long as you ask emperors, famous ministers, famous generals, and beauties in history to answer questions, you can get rewards. Su Qian directly pulled Emperor Sui Yang and Li Yuan into the question-making space. Su Gan raised the question: "What was the reason why the three expeditions to Goguryeo failed?" "What was the reason for the death of the second generation of the Sui Dynasty?" "Why was the Yang Dynasty replaced by the Li family?" "How to break the situation between the Shandong family and the Guanlong clan?" Emperor Yang of the Sui Dynasty was extremely shocked: "What?! I conquered Goguryeo three times, and all of them failed?" "I, the Great Sui Dynasty, actually died in my second life?" "Who is Li? Could it be Li Yuan's Li?!" "The Shandong family has broken up with the Guanlong clan. I beg you, sir, to teach me!" This novel and its characters are purely fictitious.
