At the end of HSDS ZMJ had Yue Fei's war tactics manual, but he left the ming sect. I assume he also left the manual behind?
Did the manual ended up in the hands of Zhu Yuanzhang? If so do you think this was the reason why he was able to drive the mongolians out of china?
Also why wasn't GJ with the help of HR and Yue Fei's manual able to do what Zhu Yuanzhang did?
