Split Sui

Yang Guang could not figure it out until his death. How could his powerful empire be defeated by a small country? How could his dream of "one emperor through the ages" be completely ruined by Goguryeo? Yang Guang was extremely unwilling and even more dissatisfied, so he conquered one, two, three, and four times. Even if the foundation of the empire was shaken and the country was about to collapse, he would try his best to hold on to the obsession that "the Sui Dynasty can die, but Goguryeo must die."
