"Because the ceremony is there."
In the external void, the path paved with void light algae leading to the Path of Light, the stone platform suspended at the end of the void, and the inverted light cluster above the platform are actually the ritual elements of a special ceremony.
In fact, Feng's decision to place the treasure in the "void corresponding to the center of the Tidal World" is also a part of the ritual.
The name of this ceremony is Tai'ander's Initial Ritual.
Tai'ander is a Whisperer who worships an Evil God. Although he was born on a remote primordial plane, he gained considerable ritual information from the whispers of the Evil God. Later, when a wizard visited Tai'ander's plane, they acquired the stone tablet notes of this ancient Whisperer, discovering a wealth of ritual information, all prefixed with Tai'ander, which added a lot of new knowledge to Ritual Studies.
