In feudal society, the blood of civilians is meaningless unless it is used for uprising. When the great poet Xin Qiji resisted the gold in Jiangbei, he was all-powerful and killed people like drinking water. In Jiangnan, there was no way to serve the country, and he was demoted 46 times in his life. Until his death, he failed to set foot on the front line of resisting gold again, and he was forced to change from a soldier to a scholar.
The treacherous court official of the bad king is in power, even if Yue Fei has the ability to set up the Central Plains in the north, the emperor's ministers will grovel, kill the general, give money to cede land and call people dad. What's the use of people trying to serve their country faithfully again? The only way is to overthrow this dynasty and replace it with a new one, but it is easy for foreign enemies to take advantage of it.
