Ye Chuqi's heart gave a little jolt. If no one else from the cultivation world had ever come here, then Eldest Senior Brother was probably the only one who could have left a trace like this. She wondered what he had done on this island to leave behind traces of a Formation.
San San said quietly, "Those traces must be several thousand years old." The coral would have needed a very, very long time to grow this large, too.
Perhaps the coral had sensed the life force here and taken root. Even the shellfish had probably been drawn by the life force remaining in the Formation. As the coral grew, it eventually reconnected the Formation. The result was far from precise, but it had sustained a faint spark of life within the Formation for thousands of years.
The coral had become part of the Formation, keeping it running while drawing more life force from it. Each sustained the other.
Unfortunately, after another look around, Ye Chuqi found nothing in the remaining traces that could identify Eldest Senior Brother. There was nothing distinctive about the Formation; anyone who set it up would probably have produced much the same thing. After thousands of years, only its most basic traces remained, and she could barely make them out thanks to the coral reefs.

"Yes, of course." Maybe Eldest Senior Brother left other traces behind!
Full of hope, Ye Chuqi squeezed along a crack in the seabed until she reached a point directly beneath the island. Then she saw the enormous hollow before her, and her mind went blank.
The underground hollow was several
