Song Dynasty: One Emperor Through the Ages

I have seen too many stories about either being the first emperor of Qin in the Qin Dynasty, or becoming a prince to save the second generation, or else living in the prosperous age of the Tang Dynasty and waiting to die... But I became Zhao Shi, Duanzong of the Song Dynasty who was about to destroy his country. There are still several years before the Battle of Yashan, but I am trying to turn the tide and save Daxia from collapse. Recovering lost territory, marching south to Dali, northern expedition to Mongolia and Yuan Dynasty, eastern expedition to Gaoguli, crossing the sea to capture Yingzhou. Become an emperor through the ages! This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
