How to utilize the magical spaces within buildings is a topic of individual perspective.
Using them as bedrooms, storage rooms, or study rooms is simply too common and seldom discussed.
On the other hand, using them as gardens is much more intriguing, and everyone is quite keen on this.
Even if it's just a space of two or three square meters, everyone wants to plant some flowers inside.
Placing a flower box inside, using special soil to plant a bunch of glowing flowers.
Or even just placing a couple of vases would be nice.
After all, they contain one's own secrets.
As for how to nourish them in such spaces, there are plenty of tutorials online, with the Magic brand's AI providing numerous explanations and demonstrations.
If the secret garden is large enough, one can even build a house inside.
The house feels incredibly secure due to its high degree of concealment.
