The protagonist travels through time and becomes Yang Guang, and is fully aware of the historical tragedy of the death of Emperor Sui Dynasty II and the underlying reasons behind it. He no longer relies on illusory systems, but relies on his own brain - a prediction of the direction of history, a knowledge system that transcends the times - as the strongest golden finger. He put on the mask of a "tyrant" and used thunderous means to fight against the noble families of the entire old world, forcing the reform and rebirth of a great empire.
