More than thirty years ago, Zi Yao left the Broken Star Field to enter the territory of the Divine Light. She had accepted the Master of the Divine Light her teacher. Since then, she had ascetically cultivated the Light power Upanishad.
Divine Light wasn't within the area of the Shadow Ghostly Prison, but it wasn't far from this area either. It was especially close to the space hub where space passages were congregated. This area was mystical, with rumors that the Divine Light would cross this place from time to time.
The Divine Light's Master didn't want Zi Yao to cultivate all the time. She asked Zi Yao to come to the space hub to see if she could get lucky and catch a glimpse of outer space divine light. If she could take it in, her realm would leap up.
