Yu Wangqiu liked playing with coins. One day, he found a coin. Later, he discovered that each time he flipped it, it took him to a different world.
First side: A New Beginning
Second side: Animal Kingdom
Third side: Who I Am
Fourth side: The Mermaid's Tears
On the third side of the coin, the needle quietly changed direction. Yu Wangqiu regained his memories, and he and Xia Xianling joined forces to lay an enormous trap that lured out the mastermind. Later, the coin broke, and they returned to their original world to continue their lives.
Note:
The first world is a transition that brings them closer. If Yu Wangqiu hadn't saved Xia Xianling, the later worlds would never have appeared.
Theme: Just do your best; the result doesn't matter.
