Every time the butterfly flaps its wings, the weak wind it brings creates a new "source", which is a set of parallel worlds with high similarity. And that butterfly, or the wind fanned by the butterfly, is the "node" of this "source". People who walk into the "source" and find the "node" can find their way back to the original time and space and find their way home. But be careful! Don't fall into the "gap"!
Song Yunqiao's friend Ling An said that there are only two kinds of people who often jump in the "source": people who have regrets that they cannot complete in the original time and space, and fools who embrace a mission. Song Yunqiao didn't know why Zhang Jingliang fell into the "source"? She only knew that she was the former. The person she loved fell into the "source", and she wanted to find his "node" and take him home.
