Modern cold medicine with special effects amazes the old world's miracle doctors; shabby, out-of-print antiques astound modern billionaires! Using the difference in goods between the two eras, Gu Shizheng launches a spectacular campaign of technological domination. He wields power in both timelines, and countless influential figures bow down before him!
