Yang Jianli, a graduate student in the Department of History, woke up and found that he was Yang Jian, the founding emperor of the Sui Dynasty who had just established the Sui Dynasty. Facing the famous Queen Dugu in history, his scheming son Yang Guang, and the treacherous court, he was completely panicked. Fortunately, the "Emperor Development System" was launched in time. What? This system does not provide magical powers or magic weapons. It can only check the loyalty of officials, analyze financial data, and deduce the impact of policies? Yang Jianli looked at the civil and military affairs of the Manchu dynasty, and decided to use his advanced historical knowledge and this "big data" system to first save his throne, and by the way, try to reverse the tragic fate of the Sui Dynasty II and create an unprecedented prosperous dynasty. Of course, with so many beauties in the country, meeting a few confidants while governing the world seems to be a "part of the job" for the emperor.
