The trip to the Yellow Springs Planet made the three great sects of the Green Branch Sect see that the Mother of Pain must have had some unknown way of learning about their infiltration plan.
On another side, one of the Three Sacred Spiritual Gates' Void Underworld expert had died, while a Void Underworld being from the Wind Transformation Sect had mysteriously disappeared.
In the end, if the Devil Emperor Shun Ying, Lu Sheng, had not killed Seven Soul Asura and activated his backup plan, they would not have been able to break free from the Mother of Pain.
Perhaps none of them could have made it back alive.
Green Branch Sect. Shun Ying Planet.
Lu Sheng named one of his own planets as Shun Ying. He planned to use it as a dwelling place for his subordinates.
He no longer had plans to return to the Yellow Springs Planet. However, he could sense that some of his cells left behind in the Anomaly Research Society were still alive.
