The protagonist transmigrates as Yang Guang, fully aware of the historical tragedy of the Sui Dynasty collapsing after just two generations, and of the deep-rooted causes behind it. Rather than relying on an elusive System, he makes his own mind his greatest golden finger: his foreknowledge of history and his knowledge far ahead of his time. Wearing the mask of a “tyrant,” he uses iron-fisted methods to take on the old world of aristocratic clans and force through the reform and rebirth of a great empire.
