The venue for the morning class is called the Flying Garden. It's not within Jiuyou Academy, but it's located in the public area of the first university.
The way to reach it is the same as with other common areas. Starting from the West Chinese Garden, we walk along the secret corridor built next to the academy's wall, and then turn off at Pavilion Number Three, you can arrive at your destination.
The environment of the Flying Garden is very similar to Green Valley, with soft grass underfoot and surrounded by endless bamboo forests.
However, compared to the elongated Green Valley, the terrain here is broader and flatter. If you say that Green Valley is a narrow valley, then this would be a mini basin.
Flying Garden does not mean that many avian magic creatures are bred here, nor does it imply this is an Enclave of the first university - strictly speaking, all the public areas of the first university are enclaves.
