Let Me Change My Destiny for the Southern Song Dynasty

I was a recent college graduate who loved reading history books, until one day I woke up on a dragon bed. I learned that this was the first year of Shaoxing, the Southern Song Dynasty? Yue Fei? Northern Expedition? Then I will do my best to change the fate of the Southern Song Dynasty. Drive away the barbarians and rescue the people. It just so happens that I brought two more books of Song Dynasty history. I will be very clear about the loyalty of all treacherous officials. The Song Dynasty will repeat the glory of the Han people in the past.
