"Of course, while Li Ou's Sanctuary is pretty great, Zhang Yanhang values the next spell—Arbitrary Gate—even more. This spell is similar to the Anywhere Door from Doraemon, as both can teleport targets, but it's a lot less powerful, probably only capable of teleporting a few kilometers."
"Although the teleportation distance is kind of lackluster, Arbitrary Gate has its advantages. For example, you can set the gate to open in a place you've never been before, as long as you have a general direction or fuzzy coordinates, it can be used successfully."
"So, this spell is really suitable for sneak attacks, like suddenly opening an Arbitrary Gate inside an enemy's heavily fortified bastion and breaking through from the inside."
