When Zhu Wanwan established the Great Zhu Immortal Dynasty, many of the measures that treated everyone equally affected the Ten Thousand Poisons Sect's dominance and also made many mountain ranges less free than before.
However, before that, Zhu Wuyang had given the 99 mountain ranges of the Thousand Poison Sect a lot of benefits, far more than what they could get in the past.
