There were supernatural powers on the island, but none were strong; the mightiest he detected with his powerful spiritual power was no more than a human equivalent to a First Level crystallized wizard. Lin Xiao quietly blended into the island life, buying a small street-front shop in a remote town and opening a little bookstore. And thus, he settled down.

What he had triggered was merely a glance from the True Dark Progenitor, not a direct confrontation – it was impossible for the True Dark Progenitor to discover his secret.
The reason for his panicked escape was just to be cautious.
