That day I climbed to the top of the mountain alone, sat by the rock and cried. Watching the sun set from the top of the head and the horizon, watching the stars rise, everything is silent.

I didn't go back to the cave until I couldn't cry.

But I rolled the other side and couldn't sleep.

I began to think seriously about my previous conversation with master and found many details that I hadn't considered in the past.

First of all, in this world, Qin did not unify the six countries, so the war lasted for more than 1000 years. What historical event caused Qin not to occupy China?

Master told me that it was Jing Ke's success in assassinating Qin.

The bifurcation of history here shows that there must be external factors that have led to the fluctuation of history.

Master didn't elaborate before, but now I know that it is very likely that the first few people who arrived and crossed changed history.

The last year of the Eastern Zhou Dynasty should be the time when the crossing man arrived on the 1st. Before that, there was no abnormality in history. After that, the butterfly effect appeared, which gradually drifted away from the historical process of my world and finally became a stranger.

As for how the people who crossed at that time influenced the assassination of Qin, whether it was intentional or unintentional, it is unknown.

Secondly, the reason why countless walkers come to this cave is their deliberate action. Because this is the "crossing starting point". According to the most simple idea, we all think that a thing should end where it happens. Although the crossing places are different, the initial point is here, so the people who cross here can explain by trudging from all directions.

The surrounding environment has been transformed by successive "masters". Living creatures are difficult to enter, traps are everywhere, and it is easy to keep but difficult to enter.

This is obviously a strategy for defending the enemy.

But what I don't understand is, isn't it unfair for other people to set this place so dangerous? For example, the man of the state of Qin who fell into a trap, this is also his home. He wanted to go home but lost his life.

Those "masters" can certainly think of what I can think of, but why do they insist on doing so? What exactly are they trying to guard against? Why did Shifu hide this from me?

Or he was looking for an opportunity to tell me everything. Unfortunately, he didn't wait.

The eastern sky showed the white belly of fish, and my thoughts came to an end for the time being. I stepped out of the cave and watched the dawn slowly infect the earth. I know that from today on, all puzzles and questions will be faced by me alone.
