Previously in the Changqing Domain, there were three Yellow Springs Underworlds that appeared one after another.
At that time, the Qing Immortal Sect was still the overlord of the Changqing Domain, so naturally these three Huangquan were also managed by them.
As for how to enter the Yin World, the sect had long had detailed records, and even Song Xiren himself had visited the Huangquan Underworld helmed by the Qing Immortal Sect many times and was quite experienced in this matter.
Upon hearing Song Xiren's account, Qing Guanzi couldn't help but ask with curiosity, "Oh, to enter the Yellow Springs Underworld, I wonder what conditions are needed?"
The original realm of the Nine Provinces was just a small world, and therefore, there were no such special Yin World existences as Yellow Springs Underworlds that are dependent on a large world.
