In other words, none of the Wizard Gardens currently on the surface of Savage Cave met the requirements.
Sanders's Gravity Garden had already surpassed the category of small Wizard Gardens. As for the renowned Garden of All Spirits, even across the entire Southern Wizarding World, it was one of the most top-tier gardens. It was even less likely to be pulled into the Dream Wilderness.
If a Wizard Garden of this caliber were forcibly pulled into the Dream Wilderness, its laws might be too powerful, placing the Dream Wilderness at risk of collapse.
"So that's how it is." Rhein spoke softly. When Angel had stated that there were limits to accommodating the laws of reality, Rhein had already guessed that the energy level of Wizard Gardens would be restricted.
It was precisely because Rhein and Sanders had both anticipated this that they had cautiously used Tidewave Garden to test the Dream Wilderness.
Looking back now, that had indeed been a stroke of foresight.
"Besides restrictions on the strength of Wizard Gardens, there are also restrictions on their types." Angel continued, "When the laws of reality enter the Dream Wilderness, they must interact with corresponding authorities."
"In other words, the types of the laws of reality and the authorities of the Dream Wilderness must be compatible."
When Angel reached this point, relief appeared in his eyes. This time, they had used Tidewave Garden, whose laws belonged to the water element. They happened to correspond with the water-element sub-authority within Celestial Change, which was why the water-element laws had successfully integrated into the Dream Wilderness.
If they had used a garden of another type—for example, a soul-type garden—
The Dream Wilderness currently had no authority related to souls. Angel even felt that it might not necessarily develop soul-type authority in the future.
