Long Street is a street at the base of Mount Mango in Cloud Empire.
Nikki and her friends pass through Long Street on their way to Moonlit City in the year 680. While they are there, they go to the Moon Inn to get a bite to eat, and run into Bai Jinjin and Zhong Lizi, who are hiding from Bai Jinjin's family. However, her father's men come for her while they are at the inn, and Nikki switches places with her while they get away. This results in Nikki almost being kidnapped, but the owner of the inn, Lu Yinian, appears just in time to fight them off.
There are many locations along Long Street, including a branch of Cloud Mill that has the spices Lunar needs to make Cloud Calico.
The Moon Inn at the end of Long Street is run by Lu Yinian. The inn serves delicious home-cooked food.
