Lin Miaomiao, a modern person, discussed with his roommate before going to bed that he wanted to travel back in time and become the protagonist in My Little Pony. As a result, when she woke up the next morning, she was found by a light green alicorn lying in a remote corner of Pony Valley. He was also a time traveler from modern times. Later, Lan Bo told him that he was actually the lord of Water City, and then the Lord of Time suddenly appeared, interrupting Miaomiao who was about to take over. In the end, when Senyu and Miaomiao fought against the Lord of Time, Senyu died.
