Elf City is actually a vast tree castle, standing in the boundless Forest of Elves.
Around the Elf City, there are thousands of ancient trees, the oldest of their kind, that surround the city, as if they are guarding their sovereign.
Interestingly, the elves are not conservative. In Elf City, there are countless people and fleets commuting between the city and its surroundings every day.
There are even practitioners from other planets entering and exiting at the city gate.
However, on the entire Elf Star, the elves are the true rulers. They can make all plants serve as their "eyes" and communicate with each other through mysterious plant interactions.
As such, any foreign practitioners who enter any place on the Elf Star, as long as they appear where there are plants, they can't escape the elves' exploration. This way, even if there are foreign invaders, the elves and treants can respond quickly.
