Heart-Breaking Spring and Autumn Period

The history pen is like a sword, piercing the heart in the Spring and Autumn Period Others traveled through time and became princes, while I became an immovable sword. Being bound to the Li family is not to show off for the protagonist, but to become the "third eye" of history. Look at Li Yuan's hesitation and the people's decisiveness, look at the undercurrents in the heyday of Zhenguan, and look at how the troubles of women, eunuchs, and feudal lords cannibalized the great Tang Dynasty. Kill the heart, kill the heart, the first thing to kill is all the time travelers including yourself! "The real history is too dangerous. Fortunately, I am just a sword." - Lin Jian.
