The time travel of Ye Mumu's children's shoes is still a mystery.
Some people said: She was too stupid, and the Creator couldn't stand her stupidity, so he just did nothing and threw her back to ancient times to fend for herself. Some people said: She was originally a species left by aliens on the earth, and she automatically traveled through time when she grew up at a certain period of time...; Others said: She maybe... Just fell into a pit, and people thought she had time-traveled when they couldn't find her.
Ye Mumu himself was ashamed to answer: This was a murder caused by a leaf...
It's very simple. Ye Mumu was walking happily on the street, and then he found a tender green leaf lying on the ground. Then he felt itchy, so he kicked the leaf... As a result, he was too stupid and his cerebellum was not mature enough, so he fell down... Then, a murder happened, and when Ye Mumu woke up, he was no longer in his own era, which was a bit sad. But she was so nervous... She was obviously not in the right state...
