Travel Through the Three Kingdoms and Become Gongsun Zan to Unify the Han Dynasty

My name is Li Xing, but I just complained about the Three Kingdoms, so I traveled through Gongsun Zan of the Three Kingdoms, determined to change history. It was up to me to change the Han Dynasty. I originally thought that by virtue of seeing the direction of the Three Kingdoms, and changing the direction again and again, history would move towards the original route of history again and again. What else can I do! ! !
