By the time Ao Zong left, Northern Polar Sky City had already changed city lords. The new city lord had known Ao Pang for a long time. He merely told Ao Pang to be more careful, saying that the Ancient Demons were wolf cubs that would never grow tame no matter how well they were fed. Conciliation alone would not do; he should wield both the carrot and the stick. He also hoped Ao Pang would secretly kill those Ancient Demons who had stained their hands with Dragon Race blood.
Afterward, Fang Yun searched through the records for a long time, but found no further communications between Manglin City and Northern Polar Sky City.
Fang Yun carefully worked out the dates and discovered that, during Ao Pang's third year serving on Manglin Star, the Prison-Suppressing Evil Dragon had attacked Northern Polar Sky City. He had conquered many areas as well, cutting off communications between numerous Dragon Race territories and Dragon City.
Based on the available records, Ao Pang ruled Manglin Star for twenty to twenty-five years. That fits perfectly with his Saint Enfeoffment twenty-five years after leaving Dragon City. What else he did on Manglin Star is unclear, but the Mountain Bearer Inheritance contains a detailed account of the first thing he did after becoming a Sage. In the year the Azure Mountain Ancestral Emperor turned thirty-seven, Ao Pang's Remonstrance took place.
The first thing Ao Pang did after his Saint Enfeoffment was seek an audience with the Prison-Suppressing Evil Dragon. Risking being killed by him, Ao Pang asked him to abandon his strict control over the Ancient Demons. Rather than treating them as an ordinary race, he should train them as mercenaries to fight Dragon City.
