Uh-huh ... actually, it's not like this. Established history means that you must go back to the past. But there is still no history of changing the general direction. . No matter how hard you try, the general direction of history will still return to the established track.

On TV, it means that heaven cannot be violated. You can try to change history through it, but history itself will reverse what you have changed. For example, no matter how Xiang Shaolong scampered, the real Ying Zheng died, but in the end, Ying Zheng sat in the dragon chair, became the first emperor, and built the mausoleum of the First Qin Emperor. The general direction will not change. It is useless to change the small direction of history, because there are no small things recorded in the history of the whole world at the end.

For example, now, can you see what a civilian left behind in the Qin Dynasty? No. Even if there is, it's just those broken cans. Those things mean nothing.
