Elf: Start with a Flashing "Green Caterpillar"

It's a new story, it's not well written, please don't curse, after all, I won't care if you curse??, To put it simply, oh, after reading so much, you should also understand that the story of a flash of light breaking the empty seat at the beginning, wandering around, there is nothing novel, and this is an urban novel, it is not a time-travel into the elf world, it is just a combination of elf and city. This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
