First of all, in A.D. 1 142, Yue Fei was brutally murdered on trumped-up charges. This explosive information quickly spread throughout the Southern Song Dynasty, and Qin Gui was pushed to the forefront. But as for the reason, we can only say that Qin Gui has nothing to lose! Who is Yue Fei? National heroes are also great. He fought in the front line for the Southern Song Dynasty and drank blood for the people of the Southern Song Dynasty, but he was such a man of the hour and was finally killed by the treacherous court official Qin Gui. At that time, the whole Southern Song Dynasty began to condemn Qin Gui.
Secondly, as the saying goes? Every man for himself, and the devil takes the hindmost? Qin Gui is like this, and so is his partner Li Guang. The Shaoxing meeting decided the fate of Yue Fei, and Song Gaozong and Qin Gui drew Li Guang into their own camp during the discussion. Li Guang didn't disagree with this matter, but after Yue Fei's death, the whole world changed. Qin Gui was despised by the people of the Southern Song Dynasty, and his partner Li Guang began to change his position, perfectly shirking the responsibility of the whole thing.
Then, there are other reasons for Li Guang to straighten his position so quickly. Qin Gui can bear the title of the first treacherous court official in DaSong, and his ability is not to be underestimated, so after the successful negotiation, he began to seize power with great fanfare. Therefore, to be on the safe side, Li Guang publicly condemned Qin Gui, accusing him of playing with power and bewitch the king. In this way, two people who were partners became incompatible political enemies.
Finally, Li Guang's behavior is also caused by the current situation. Considering the situation in North Korea and the popular feeling in the Southern Song Dynasty, it is a wise decision to formally break with Qin Gui.
